It’s academic

by screamingmoist   

An aging professor falls prey to a former student.

Hank watched the young man lap him for the second time, seemingly no worse for the wear. The spry young man was shirtless, showing off a ripped, deceptively built torso. At first glance he could be mistaken for skinny until you saw the defined pecs, six-pack, and arms that doubled in size at the slightest movement. He had on a pair of small, thin running shorts that showed off his long, toned legs and perky bubble. The younger man had no idea he was in a race, which was good for Hank. Hank was giving it his all and coming nowhere close to keeping up. He understood on a logical level that as he got older it was going to get harder to keep in shape. The fact that he was still as built and fit as he was at 46 spoke to his dedication when it came to diet and exercise. When it came to looks and athletic ability he could still hold his own with these kids half his age, but he’d be lying if he said he didn’t resent the hell out of them for making it look so easy. He toughed it out until he hit the nine-mile mark before throwing in the towel. He told himself it was all his extra muscle that made it harder for him than the lithe young stud who’d run circles around him.

“I thought that was you out there!”

Hank turned from his locker to see the source of his ire standing behind him. The young man’s damp frame was clad only in a towel, the dripping water further accentuating his lean, shredded frame. He wasn’t bulky, but each of his wiry muscles popped with definition. Hank looked him up and down. He hadn’t noticed on the track, but standing face to face the broad grin and shaggy hair looked familiar. “Josh,” the young man said before Hank could ask. “I was in your afternoon class last fall.”

“Oh, Josh! How are you?” Hank forced a smile in return and shook the outstretched hand. Josh had been one of his best students, but something about him had always rubbed Hank the wrong way. Josh was one of those smart, smug students who always gave the impression that he was laughing at a joke only he was in on. Hank knew that feeling well since he had a tendency to do it too. He crossed his much larger arms over his burly chest and puffed himself up slightly, flexing in an unconscious attempt at superiority. All Hank had on was a pair of red boxer briefs, and while he normally wasn’t uncomfortable by a lack of clothing, the way Josh looked at him made him uncomfortable. He wished he’d used the faculty gym that afternoon. He wouldn’t admit it, but he liked using the student gym because it made him feel young. “Weren’t you going on to grad work?”

Josh nodded eagerly. “Just started this semester. I got into the chem program here. I could’ve moved on, but I guess I’m stuck here for a bit longer.” He moved over to a locker a few spaces down and let his towel drop, showing off his tight bubble and long, thick hose between his toned legs.

Hank couldn’t help but wince. Not only was Josh in better shape, he was hung, too. Hank had been thinking back to their class, and he didn’t remember Josh looking so good. He tended to pay more attention to how his female students looked, but he remembered Josh as being wiry and bony. “Looks like you’ve been working out,” Hank said with a raised eyebrow.

“Yeah,” Josh grinned, sliding on a pair of small black briefs. He reached into his locker and tossed Hank a water bottle. “I figured I wasn’t getting any younger, so I’d better get to it.”

“Thanks,” Hank said, draining the bottle in one go. “Whatever you’ve been doing, it looks like it worked.”

“It’s not just the gym…I’ve been working on my own supplements. It’s what I’ve decided to focus my grad program on. So far so good,” he said, flexing a solid arm and motioning to his six pack abs.

“I’d say so,” Hank whistled. “Got any extra?” He laughed, making a joke, but Josh’s face was suddenly serious.

“Actually,” Josh cocked his head to the side and looked Hank up and down, “if you’re seriously interested, I’m looking for participants. Some of the guys in the house volunteered but I need someone a bit older.”

Hank shook his head. “I don’t know if I’m your guy…”

“It’s one hundred percent safe. You can talk to the other guys before making your decision if you want.”

“I appreciate the offer, but I think I’ll pass.”

“Oh, yeah, no problem. I just saw you struggling out there on the track and thought you might be interested.” Hank bristled. He couldn’t tell through Josh’s cordial tone if that was an intentional dig. “I mean, not that you need it,” Josh continued quickly, seeing Hank tense. “I mean, look at you! You’re a stud, clearly. This would just be a boost.”

Hank had no idea why he was even considering it. He didn’t particularly like Josh, and he didn’t like the idea of home-brew, experimental steroids. And yet, the longer he looked at Josh’s shredded physique and thought about how easily he loped around the track the more curious he became. “All right, all right,” Hank sighed. “You’ve got me interested. I’ll at least come talk to the guys and look it over, but no promises.”

Josh was elated. He grinned from ear to ear and let out a deep breath he’d been holding. “Oh man, I’m so glad to hear you say that. You won’t regret it! Trust me…as soon as you see the results and the safety data you’ll…” he broke off, shaking his head. “Sorry, I’d go on all night. We’ll talk later.” Josh jotted down his address and they made plans for Hank to come by after his evening class. Hank finished dressing when Josh left, suddenly wondering why he’d been so quick to agree.

By the time Hank reached Josh’s house that evening, he’d already decided to back out. He thought about just not showing, but his pride wouldn’t let him. He’d go, politely decline, and then forget it. His plan lasted until the door opened.

“Uh, hi…I’m looking for Josh?” Hank couldn’t help but be taken aback by the adonis that opened the door. He was as straight as they came, but the young, shirtless man in front of him was objectively beautiful. He had trim black hair, a lantern jaw, and cheekbones that could cut glass. His thick, broad shoulders flowed into a matched set of huge, granite arms that framed his sculpted pecs. His shredded stomach was boxed in by deeply cut obliques that disappeared into his stuffed gym shorts. Looking at the large bulge was unavoidable as the shorts were plastered on his wide, solid thighs. The young man didn’t appear to have an ounce of fat on him.

“Oh, hey, are you the prof?” He asked with a bright smile, seemingly oblivious to Hank’s staring. “Come on in.” Hank couldn’t help but gawk at the large, shifting globes straining out the back of the man’s shorts as he followed him in. “I’ll grab him for you.”

Hank looked around the house while he waited in the entryway, still reeling from the unexpected vision of perfection that opened the door. It was clear that a group of college guys lived there. The furniture was mismatched, it looked like the cleaning schedule was inconsistent at best, there was random clutter and articles of clothing scattered around, and the entire place was covered in the unmistakable smell of sweat and cheap cologne. He remembered these days fondly, but thinking about his own large, immaculate home, he didn’t exactly miss them.

A motion at the top of the stairs caught his eye, and Hank looked up in time to see another surprisingly buff man coming towards him. Like the first man, all he had on was a pair of small gym shorts that left his equally impressive frame on display. Whoever he was, he wasn’t as tall as his friend, but he was every bit as built.

“Hi, are you Professor Hank?”

“That’s me,” Hank said, shaking the man’s wide, firm hand. Even though he was a good five inches taller, he felt small next to the man’s broad, solid body.

“I’m Bill. Josh said you’d be coming by. You’re interested in his program?”

“Uh…maybe? That’s what I’m here to talk to him about.” Hank was still unarmed a little from the two men. Unlike the first man, Bill’s broad, burly body was covered in an ample dusting of wiry brown hairs that matched the mop on top of his boyish, handsome face. Hank was discovering that it wasn’t just their looks; the two men had an undeniable presence about them that he wasn’t used to. Or at least he wasn’t used to being on the receiving end of it. “Are you one of the people he already roped in?”

“Yep!” Bill grinned from ear to ear and broke into a double bicep pose, his furry torso exploding outwards in a display of thick, striated muscles. “If you could believe it, three months ago I was just a short fat guy. Don’t worry,” he said, cutting off Hank’s response, “Josh has all the pictures. Bryan didn’t look like this either. He’s the one who let you in.”

It sounded too good to be true. “But…how? I mean, even with steroids there’s no way you’d get from a “fat” guy to where you are now in that time.”

Bill just shrugged his broad shoulders. “I leave the science to Josh. I just know it works.”

“Sounds like good timing,” Josh said, rounding the corner. “I see you met Bill. And this is Bryan,” he said, motioning to the walking sculpture next to him. Bryan’s smooth, tan skin practically glowed. He smiled at Hank’s stunned expression. “See? I told you you’d be interested.”

Hank let out a sigh, shaking his head. “That’s one word for it.” He followed Josh down to the basement, feeling like he’d stepped into another building altogether. The rest of the house may have been a typical bachelor pad, but the basement looked like a legitimate laboratory. None of the many beakers or vials looked out of place and the entire area was spotless.

“Don’t let the upstairs fool you,” he said, reading Hank’s expression. “Down here it’s all business.”

“Josh…level with me. Those guys up there….did they really…?”

“See for yourself.” They sat on a pair of stools and Josh pulled up a file on his laptop. “These aren’t the official pictures and videos. I’ve blurred out everyone’s faces for those, but I want you to be convinced.” On screen, a short, hairy, slightly overweight, and very naked man walked into frame. He was clearly uncomfortable at being naked in front of the camera.

“And you swear you’re going to blur the faces out and not use anyone’s names, right,” the man on screen asked. The voice cemented it. It was hard to tell with the rounder face, but this was Bill. Not the shredded, burly man he’d just met, but the dumpy, out-of-shape version.

“Dude, for the last time, yes,” Josh said from off-camera as Bill turned in a slow circle, arms outstretched. “Now are you ready?” He didn’t wait for an answer. He came into frame and stuck a needle into Bill’s doughy behind. The naked man laughed and winced.

“Is that all?” Bill asked on camera.

“Until tomorrow,” Josh said, leaving the frame again.

“I spliced together a time lapse,” present-day Josh said, bringing up another file. It was the same routine: a naked Bill would enter the frame, turn in a circle, and Josh would stick him with a needle. At first it didn’t look like anything was happening, but Hank couldn’t hold back a gasp when the changes kicked in. All of a sudden it was as if the fat was melting off the naked man. As he slowly rotated, his body changed with each revolution. He looked like he was being drawn into himself at first, before he started expanding again. Only now it was his shoulders that pushed outwards while his stomach drew inwards. His chest and arms gradually grew larger while his thighs took on more and more definition. Bill didn’t look nervous or awkward anymore. He was positively beaming as he stood proudly naked in front of the camera, flexing his large, now-solid ass and grinning from ear to ear. He thought it was just the weight loss, but Hank also noticed Bill’s formerly smallish cock growing noticeably longer throughout the progression until it swung slightly as the newly formed stud turned in his circle. “See? Impressive, right?”

“I don’t…” Hank stammered. “I don’t even know what to say….”

“Check out Bryan.” Josh pulled up another time lapse, this time of a tall, somewhat doughy and awkward looking young man. Like Bill, the first few rotations showed a clearly uncomfortable Bryan bashfully turning in a circle, but like before, he quickly started filling out. Unlike Bill, Bryan didn’t have as much to lose, so he started expanding almost from the start. His flabby midsection melted away to a solid eight-pack while his back and shoulders pushed outwards into a perfect V. His enlarging arms started to hang at an angle and his bird-like thighs started pushing towards each other. He’d had no ass to speak of in the beginning, but now he had a set of large, meaty globes. He’d been fairly well endowed to start, but that didn’t stop his cock from widening to match the rest of his perfect proportions. As impressive as Bryan’s body was, Hank was most surprised by the changes to his face. He’d had an asymmetrical, ungainly appearance before. His lips were thin, his nose was long, and he’d had no chin. Now he looked like he could be a model as the Bryan on-screen casually sauntered naked in front of the camera.

“So there you have it,” Josh said proudly. He pulled up a series of charts while Hank stared in shocked silence.

“What…what am I looking at?” He finally said.

“All the other relevant figures. Liver enzymes, kidney function, EKG results, cholesterol, blood pressure…all perfectly healthy. If you look,” he said, tracing a line, “you’ll see that they actually improved across the board. Like I said: perfectly healthy.”

“Okay, I’ll admit it, I’m impressed,” Hank said with a wry grin.

“So are you in?”

Hank didn’t know what to think. His head was swimming from what he’d just seen. It all seemed too good to be true, but he couldn’t argue with the results. And he found himself wanting to agree with Josh. Like the two men upstairs, his former student had a commanding presence that was both overwhelming and disarming. The more time he spent around him, the more he wondered why he’d ever been uncomfortable around him. Finally, Hank shrugged. “Sure. Why not?”

“Great!” Josh clapped Hank on the shoulder excitedly. “You’re going to love it.”

“So what’s the plan? Do I come back later? When did you want to get started?”

“We can do it right now if you want.”

Hank hadn’t been expecting that. “Uh, yeah, okay.”

“Perfect!” Josh eagerly went about setting up the camera and a series of syringes. “Go ahead and get undressed while I get everything ready.”

Hank felt an unaccustomed rush of nervousness at the idea. He and Josh had just been naked around each other earlier that afternoon, but after what he’d just seen and the two men upstairs he was suddenly insecure. He bit it down and peeled out of his tight polo and slacks. He started to pull down his boxer briefs but decided to leave those until absolutely necessary.

“Okay! Let’s get to work.” Josh went about taking a series of measurements: weight, height, body fat, and various circumferences. “You’ll need to lose the shorts for the rest,” he said gently. “This part’s a bit intimate.”

Hank slid them down, trying to hide his nervousness. “Whoa!” he laughed when Josh grabbed his package to take the measurement. It wasn’t a long, thick hose like Bill or Bryan, but the stout, wide cock filled Josh’s hand. “A little warning next time.”

“Sorry, I get on autopilot,” Josh said as he wrapped up the measurements. “But we’re done with that. Now I just need to take a baseline blood sample and then we can administer.”

Hank stood still while Josh pricked his arm and filled a small tube. He was impressed with his former student’s clinical approach. Instead of feeling awkward, Hank felt like he was in a doctor’s office.

“All right…if you can go stand in front of the camera and give us a slow turn, we’ll do the shot.”

Despite himself, Hank blushed. “I get why Bill and Bryan looked so uncomfortable,” he said gruffly as he turned.

Josh laughed. “Those two, yeah. But you’re on another level compared to where they started.”

Hank swelled at the compliment. It was what he needed to hear. He knew he looked good. His shoulders were broad and his beefy arms were solid. His chest was a slab of muscle above his firm, flat stomach, and his trunk-like legs sported an ass that was still round and tight. Like Bill, he was covered in a slight coating of wiry blonde hairs that matched the unfortunately thinning ones on his scalp and accentuated each of his impressive muscles. With a ruggedly handsome face, he was the picture of masculinity. He braced himself when he felt Josh’s hand on his ass. It suddenly occurred to him that he was naked in a student’s basement about to be injected with a strange drug. Before he could change his mind he felt the needle stick.

“Slight pinch and a little sting is all you should feel,” Josh said as he pushed the plunger down. “All done!”

Hank just blinked. He didn’t know what to expect. “I probably should have asked before, but any side effects I should look out for,” he asked when his head finally cleared.

“No major ones have been noted so far. It’s hard to tell with a bunch of guys in their twenties, but the most we’ve seen is increased energy, elevated mood, and a bump in libido.” He shrugged. “I mean, whether that’s the drug, or just some horny guys being happy about their new look is up in the air.” Josh went about putting his equipment away while Hank got dressed. “In your case, the variety of supplement should kick in quicker than with Bill and Bryan. You’re already in better shape than they were, and I’ve learned from their results how to hopefully speed it up a little.”

“So when do I come back,” Hank asked, feeling a little overwhelmed. This had all happened randomly and quickly, which still made him nervous.

“Daily. That’s important. We need to maintain a pretty strict dosing schedule, but otherwise go about your day as usual.”

Hank was still hoping he hadn’t made a mistake as he followed Josh upstairs.

“Since you guys were down there so long, I take it that means you’re in,” Bryan asked, sprawled out on the couch. He’d swapped out the gym shorts for a pair of small, stuffed green briefs. Bill was similarly dressed and draped in a chair next to him.

“Looks like it,” Hank said, marveling at the changes he’d seen in the two of them.

“Awesome! You won’t regret it, man.”

“Welcome to the club!” Bryan reached up a hand for a loud high-five.

Bill nodded toward the baseball game on the TV. “You wanna stick around and watch the game?”

“Maybe next time. I’ve gotta be in the office bright and early tomorrow. Full day of classes.”

“We’ll see you tomorrow, then,” the hairy man said with the same bright grin.

Hank woke the next morning feeling better than he had in years. He came to gradually, stretching his bulky frame contentedly on his large bed. Hank had grown used to a constant mix of dull aches and pains as he’d gotten older, but he felt none of them. Knees, back, shoulders; everything felt great. The only thing that ached was his solid, throbbing cock. He couldn’t remember the last time he’d woken up with wood like this.

“Increased libido is right,” he laughed. He kicked his sheets off, surprised to find that he was naked. Usually he slept in his underwear but for some reason he’d stripped down. He didn’t actually remember going to bed. His memories of the previous night were hazy at best, but he told himself it was just from being overwhelmed by the possibilities of Josh’s drug. He reached down and grabbed his eager pole, gasping at the unexpected intensity of what he felt. As soon as he made contact a jolt ran through him. “Geez!” He sighed, feeling his muscular torso with his free hand while he stroked. Nothing seemed different. Not that he’d expected it too. It had taken a while for things to kick in with Bill and Bryan. And even though Josh said it should happen more quickly, he couldn’t expect a dramatic change overnight. He thought back to how Bill and Bryan had looked at the start of their treatments, contrasted with the underwear-clad hunks he’d seen when he left. “Ooohhhh!” Hank moaned and arched off the bed, his cock erupting in a geyser as he thought of the other two. When he was finally done soaking himself and the sheets he told himself it was just bad timing that he’d been thinking of the two men when it happened.

He went about the rest of his morning and into the office feeling like a new man. He had so much energy he didn’t even stop for his standard morning coffee. He was in such a good mood that he was actually looking forward to his first Advanced Micro-Economics class, instead of slogging through it like he usually did. Even for someone with a doctorate in finance, advanced economics was a chore first thing in the morning. But now he flitted around the room, surprising his tired students with the sudden burst of energy. His good mood lasted until halfway through the class.

Part of the reason Hank liked to pace around the room while he spoke was because it helped him think. The other reason was that it let him check out all the twenty-something coeds in the room while those same ladies got to check him out. He was dressed in a tight button-down that showed off his powerful torso and a matching pair of equally fitted slacks that drew attention to his taut rear end. As he went around the room, he kept finding his eyes drifting to the sleepy brunette in the front row. He liked brunettes, but he didn’t usually like them to have dicks. The sleepy student he kept going back to was a lean, wiry junior named Tristan. The young man’s thick brown hair was still messy from bed, his cheeks were still covered in prominent stubble, and his dreamy eyes were struggling to stay open. Hank tried to focus elsewhere, but he kept going back to the way the young man’s tight shirt showed off his lean torso, and the way his thighs spread together in his mesh shorts while he sat. Hank wondered if the rest of him was as hairy as the rocky calves and long, flip-flop-clad feet that stuck out from under the desk.

It was as he was thinking about all this that he felt his cock twitch. It happened so suddenly that he barely managed to turn towards the whiteboard and make his way back to the podium, praying that no one saw and cursing himself for wearing such tight clothing. The second half of the class took all of his concentration, both to ignore the now-rigid cock in his pants and the urge to continue walking around. He stayed behind the podium until the class was done. He’d answered the few questions from the stragglers after the bell as casually as he could, but all he could think about was what would happen if one of them saw the hard cock outlined in his pants. As soon as the room was empty he grabbed his bag, slung it in front of his crotch, and tried not to run to his office.

“Professor Fitzgerald, you’re first appointment’s here.”

Hank silently cursed the receptionist and his waiting student as he hurried past them. “Sorry, I’ve got an emergency call waiting. It’ll just be a minute.” He shut and locked the door, sighing as he leaned back against it. For the first time, he was glad his office didn’t have windows as he fished out his aching cock. He couldn’t believe what he was doing. He’d hooked up with a student in his office once, but he’d been so paranoid afterward that he’d sworn never to do it again. And now here he was about to jerk off. He started to reach down but stopped, remembering the explosion from that morning. The last thing he needed was a cum-stained office. Hank was frantic as he dug through his spare gym bag and pulled out an old t-shirt, his face burning even harder as he felt his solid cock wagging around exposed in his office while he did so. He pumped into it a few times, barely managing to bite down on his fist in time to stifle his moan when he abruptly came. He stood spasming, his knees weak, while his cock sprayed stream after stream, soaking the shirt.

“Definitely need to talk to Josh about that,” he panted, dropping in his desk chair. Despite his humiliation, he felt wonderful. It was deeper than the typical afterglow; like his whole body was liquid. He quickly stuffed the shirt back in the bag and sprayed on cologne to mask any smell, feeling like a teenager trying not to get caught by their parents. When he finally softened enough he stuffed himself back in his pants and tried not to think about it.

Hank made it through his morning and most of his afternoon classes before it happened again. He made it a point to stay behind the podium for each of the lectures so he wasn’t left scrambling, but as the day went on he found himself increasingly focused on his male students. It was the end of the day before he realized he hadn’t even given his female students a second thought. He went through the same motions as earlier, locking his office door and pumping into his damp shirt like a jackrabbit. He told himself this would all level out. If not, he’d have to keep a steady supply of rags in his office.

Surprisingly, he was less worried the second time. Despite feeling awkward and slightly embarrassed, his good mood hadn’t cracked as the day went on. And while he was confused by his behavior, he couldn’t bring himself to be overly concerned. He was too busy feeling better than he had in years.

After his classes, Hank breezed through his workout. Usually he had to strain to the point of exhaustion, but he actually felt refreshed when he went back to the locker room to get cleaned up. Like in his classes, he was having a new experience at the gym. Especially in the locker room, surrounded by fit men in various states of undress, he felt overwhelmed. He was so focused on the men around him that he didn’t even realize he’d stripped naked, with his thick, solid cock as eager as ever and on display until he finally caught a glare from a passing student. His whole body blushing, he kept his towel firmly in front of his crotch and scampered into a shower stall. He was mortified, but not so much that he didn’t spray for the fourth time that day.

He didn’t know what to think as he made his way to Josh’s house later that evening. Part of him wanted to discontinue the treatments. He knew something wasn’t right. But at the same time, he couldn’t deny how good he felt. He had none of his aches and pains, he wasn’t dragging at the end of the day, and he was still just as horny. True, there had been some embarrassing moments during the day. He could have done without the awkward scene in the locker room especially, but it also felt good to feel so virile again.

“So you decided to come back?” Josh had a warm smile and clapped Hank on the shoulder when he ushered him inside and down into the basement. “How’re you feeling?”

“Great! Better than I have in ages, actually…”

“I sense a ‘but’ coming.”

Hank blushed. “You weren’t kidding about that libido part.”

Josh went from friendly to all business. “What do you mean?”

“I’ve, uh, jerked off four times already today and it feels like I could four more times,” Hank said awkwardly. “There was almost an embarrassing moment in front of my morning class, and I kinda lost track of things at the gym.”

“I’m confident that’ll even out. It’s just a matter of adjusting. Like I said, you’re our oldest test subject so far. Given that libido drops after a certain age, that’s probably hitting the hardest. A lot of hormones and receptors are suddenly reactivating. But I’ll totally understand if you wanna call it.”

Hank was silent. Being back in the house brought back the memories of Bill and Bryan and their transformations. And Josh had been so excited when he’d said yes. “No, let’s keep going. I mean, I feel like a new man otherwise, and that was only after one day.” Hank couldn’t help but return Josh’s eager smile.

“Awesome! I think you made the right choice. Go ahead and get undressed so we can take the measurements and get your dose.”

Hank stripped naked without even thinking about it. He was kicking off his boxer briefs before it even occurred to him that he could’ve waited until absolutely necessary for that part. He shrugged it off. Josh had already seen everything and the young man was good at putting him at ease. And, he was surprised to realize, it just felt good. He hadn’t noticed how confined he’d felt in his button-down and slacks.

Josh came over and started going through the measurements as he had the day before. The difference this time was that as soon as he touched Hank, the older man’s still-eager cock rocketed to attention.

“Shit…uh…sorry,” Hank stammered, his whole naked body flushing.

Josh was unfazed. “Don’t even worry about it. The other guys had the same issue. It actually helps when we measure down there.”

Hank wanted to make small talk to distract himself, but he was already plenty distracted. Every time Josh’s hand made contact with his bare skin he felt a shiver run through him, surging straight to his aching cock. Hank started to wonder if he was just imagining Josh touching him more than the day before. He told himself the extra sensitivity just made it seem that way. He tried not to think about it when Josh’s hand started reaching toward his crotch. He hoped what he knew was coming wouldn’t happen. “OOHOHHHhhhh!” Josh’s hand had barely come into contact with his throbbing organ when he exploded. There was no time to stifle his cry or to try and contain himself. All he could do was spray like a fire hose and try not to fall over while he groaned like he was being tortured. He clutched at Josh’s surprisingly solid arm and stared at the young man with wide eyes. “Oh…oh god…I’m so sorry. I didn’t…I couldn’t stop myself from…” Hank stammered, panting and beet red.

“Easy there, Prof,” Josh said calmly. He put a hand on Hank’s shoulder and felt the older man relax. “Don’t pass out on me,” he laughed. “This is actually really useful data. Did you always produce that much,” Josh asked, motioning to the ample fluid on the ground.

“No, never like that. Especially not after so many times,” Hank said, still mortified. “Jesus, I made a mess didn’t I? At least let me clean that up…” he grabbed a roll of paper towels off a nearby table and dropped to the ground to wipe up his mess. That small part of his brain that had tried to warn him was trying to get his attention again. It was screaming at him that he was naked on all fours in a student’s house wiping up his cum. It was begging him to get out of there. The confusing feeling that ran through him when he looked up and saw Josh staring down at him drowned it out entirely. He sat up on his knees, coming face to face with Josh’s crotch. “I, uh, think I got it all.”

“Thanks, man, I could’ve gotten it,” Josh said, watching the older man stare at his crotch.

Hank shook his head and stood. “Least I can do,” he said, clearing his throat. “So we ready?”

“Yep. You know the drill.” Hank took his place in front of the camera and did a slow turn like the previous day. “It’s going to be hard to tell when this kicks in…you really are in great shape, Prof.”

Hank swelled at the compliment. He puffed his meaty pecs out and felt himself flexing his perky cheeks. He drew his flat stomach as tight as he could. “So is this going to give me abs?”

Josh laughed. “Not that you need ‘em, but yeah, it should.” He came over and stuck the needle in, giving Hank’s ass a squeeze afterwards this time. “All right stud, all done.”

Hank reluctantly got dressed. He knew he had to, but suddenly he didn’t want to. “Same time tomorrow,” he asked as they made their way upstairs.

“Yeah, if that works for…”

“Hank!” Bryan’s eager voice cut Josh off. Like the night before, the sculpted hunk was sprawled on the couch in a pair of tiny briefs. “I didn’t know you were here, man. I would’ve come down and said hi.”

Hank blushed at the thought, not sure if he was glad that Bryan hadn’t seen what happened, or if he felt disappointed. “Just wrapping up,” he said, trying not to stare at Bryan’s huge bulge.

“Aww, don’t tell me you’re leaving already? The game’s just about to start. Bill’s gonna be home in a minute. You should stick around!”

“I’m not sure I…”

“Dude, you bailed on us last night,” Bryan said, sitting up and fixing Hank with a mock-glare.

Hank was surprised by how much he actually wanted to stay. “Okay, what the hell…I don’t have an early morning class tomorrow.” He felt his stomach flutter at Bryan’s smile when he agreed. He was twice the young hunk’s age, but it felt like Bryan was the one with the authority.

“I’ll grab some beers!” Bryan hopped up and scampered into the kitchen with Hank’s eyes glued to his broad back and bouncing cheeks the whole time. Josh excused himself to go work on the evening’s data and Hank settled into the couch when Bryan came back with the drinks, falling quickly at ease with the other man. He listened to Bryan complain about his classes that semester, noticing for the first time how deep and smooth his voice was. It was relaxing to the point that Hank had to force himself to pay attention to keep from drifting off.

“Hey, the Prof stuck around!” Bill was just as eager to see him when he came through the door. He tossed his bag aside, kicked off his shoes, and then immediately peeled his skin-tight t-shirt off, exposing his hairy, beefy pecs and washboard stomach. “Game start yet?”

“Nope! Just about to,” Bryan said, tossing him a beer. Hank watched while Bill casually undid his equally tight jeans and squirmed out of them with his one free hand. The young man’s thick, hairy thighs flexed and shook while he struggled to kick them free.

“Uuugggghhh, that’s better!” Bill sighed and kicked the jeans next to his shirt, stretching his thick arms overhead. “I couldn’t wait to get the fuck outta those all afternoon.” He snapped the waistband of his briefs and adjusted his stuffed pouch as he dropped into the chair next to Bryan with a soft thud. “Dude, Prof, you can relax here.” He laughed at Hank’s confused look.

“You’re a little overdressed, is what he’s saying,” Bryan said, tugging on Hank’s shirt sleeve.

“Oh! Uh, nah, I’m…” Even as he started to say he was okay, Hank could feel his skin crawling. Seeing Bill undress had been like dying of thirst and watching someone take a drink of water.

“Hey man, you’re in the club now, it’s cool,” Bryan said as he clapped Hank’s thigh. “Probably not an issue for you, but after years of looking like we did, me and Bill aren’t in a hurry to cover up so much anymore.” He leaned back on the couch, spreading his meaty legs and settling in. “We got it, so we’re gonna flaunt it.”

Hank couldn’t argue with their logic. And they did seem more comfortable than him. “All right then,” Hank said, hopping up. He unbuttoned his shirt and tossed it aside, feeling like a weight had been lifted.

“Damn, Prof!” Bill whistled from his chair while Hank undid his slacks and let them drop. “Josh wasn’t kidding. You are a stud.”

Hank grinned and broke into a double bicep pose, feeling surprisingly happy at the way Bill and Bryan were checking him out. He’d thought he’d be self-conscious in front of their perfect bodies, but it wasn’t like that. He felt relaxed and free, like he hadn’t felt in years. They made quite a sight, the two young men with their perfect bodies and Hank with his older, bulkier frame, all nearly naked.

“Welcome to the club,” Bryan said by way of a toast. They chugged down their beers and Hank flopped back down on the couch. As the night went on he felt more and more like a college student again and less like a professor. He forgot how much he missed just hanging out with the guys like this. He lived alone and typically viewed other guys as competition. This wasn’t like that. Around Bill and Bryan he felt totally at ease. He dropped his guard and didn’t even think twice about what was going on. He was happy just being around them.

Hank was so caught up that he entirely lost track of how long they were all hanging out until Bill let out a loud yawn. “Damn,” the burly man said, standing and scratching his hairy abs. “How is it almost three?”

“Shit!” Hank yawned and stretched, trying to force himself up off the couch.

“Dude, just crash here tonight,” Bryan said.

“Yeah, for real man, it’s fine. Just crash on the couch if you want.”

Hank didn’t really want to leave anyway. “You sure it’s cool?”

“Of course!” Bill reached down and tousled Hank’s blonde hair when he said it, eliciting a sleepy giggle that surprised the older man. “Just make yourself at home.”

“G’night dude,” Bryan waved, clicking off the light as he and Bill went upstairs. Hank sprawled out on the couch, feeling totally content. He tried to remember the last time he’d actually slept on someone’s couch as he drifted off to sleep.

Hank stirred slowly. His first thought on opening his eyes was that he had no idea where he was. He was face down on a couch that wasn’t his own.

“Mornin’ sleepy head.”

Hank turned his head, squinting against the bright sunlight and saw Bryan sitting in the chair. The young man’s hair was still messy from bed and he had a thick stubble on his lean cheeks. He was drinking coffee with one hand and checking his phone with the other. Despite his confusion, Hank smiled at the sight of the other man, the memories of the previous evening slowly coming back. “Mornin’,” he yawned, sitting up on his elbows and trying to blink the sleep from his eyes. Despite his awkward position, he’d slept like a rock. “What time is it?”

“Just after nine.”

Hank was surprised. Even when he stayed up late he didn’t sleep much past seven in the morning. As he’d gotten older, sleep was harder to come by. He sighed and forced himself upright, noticing for the first time that he was stark naked. “Whoa!” he laughed, blushing. Like the previous morning, his eager cock was sticking straight up between his burly legs. Also like the previous morning, he didn’t remember taking his underwear off during the night. He looked around quickly for his discarded clothing but didn’t see anything. “Uh…do you know where my clothes are?”

Bryan looked over and shrugged, not at all fazed by Hank’s nudity or rigid pole. “Josh probably picked ’em up with our stuff and threw it all in the laundry. He’s picky like that,” Bryan said, rolling his eyes.

“Do you know where my underwear got off to?”

Bryan shook his head. “You were like that when I came down. Don’t worry, dude. You can borrow some of ours. Josh and Bill are already gone but we can track your stuff down later when they get back.” Bryan stood and Hank saw the other man was still in the same briefs as the previous night. His already hard cock throbbed even harder when Bryan’s stuffed bulge passed inches from his face when the other man walked by. “You okay,” he asked, grinning down at Hank.

“Yeah, yeah, just out of it,” Hank said awkwardly. “Not used to waking up like this.”

“Then you need to have more fun,” Bryan said, pulling Hank to his feet. The older man blushed as he felt his solid cock bouncing while he followed Bryan upstairs. Instead of being embarrassed, he felt a thrill at being naked in a strange house. “I’ll grab some stuff from Bill…it’ll probably fit you better. Shower’s in there if you want to wash up.”

Hank slid the glass doors open and cranked the shower on. He stood under the warm water, feeling more loose and relaxed than he should for having spent the night on an old couch. He felt stiff when he slept on an expensive king bed, but waking up face down on a worn-out couch left him feeling like a million bucks. He didn’t even think about it when he wrapped a hand around his cock and started stroking. Unlike the previous morning he didn’t have an instant explosion. This time he had a bit longer to think about the previous night. Without meaning to, he thought back to how Josh’s hand had felt when he was being measured. Then he started to wonder what it would feel like if Josh was the one jerking him off instead. Then Hank started to wonder what Josh’s dick would feel like in his hand instead of his own. “UUUUUnnnnnnnn,” he grunted and bucked his hips, dousing the wall of the shower.

“Sounds like that felt good.” Hank froze at the sound of Bryan’s voice as the other man came into the bathroom. He started to panic, but never got beyond a few rapid heart beats. Why should he care that Bryan saw that? “Looked like you needed it,” the younger man said with a cocky grin.

“I sure did,” Hank sighed. “Been happening a lot lately.”

“Oh, I know. This stuff makes you super horny, especially at first. You get used to it. It’s actually pretty cool…makes messing around a whole lot more fun.”

Hank turned the shower off and slid the door open, taking the towel from Bryan as he stepped out. He was surprised when the other man shucked his briefs, his long, thick hose bouncing half-hard out of the tight underwear. “I’m gonna jump in too.”

Hank had a hard time looking away from the naked adonis in the shower to the pile of clothes on the counter. He felt a thrill at sliding on a pair of Bill’s bright, tiny briefs. He wasn’t sure why the thought that he was wearing another man’s underwear turned him on as much as it did. He wiped the steam from the mirror and blinked in surprise at what he saw. He looked younger. The wiry coating of hairs had disappeared from his body, save from a dusting on his arms and legs. He reached up and ran a hand through his hair, his blonde locks feeling thicker than they should. It could have also been the lighting, but he thought it was a lighter shade of blonde than he was used to. Beyond his hair, his face was noticeably less wrinkled. The creases on his forehead weren’t as deep and he looked less weathered in general. The effect wasn’t anything that couldn’t have been achieved at a spa, but he took it as a sign that things were working. He pulled on the tight t-shirt next, shivering at the foreign feeling of the soft cotton on his now-smooth skin. The thin material made each of his ample muscles pop noticeably like he wasn’t wearing anything at all. The small blue shorts he pulled on did the same with his lower half, bulging out in a noticeable lump at his crotch while the back was wedged between his two solid globes.

“Lookin’ good, Prof!” Bryan stood in the open shower doorway, toweling himself dry while he watched Hank inspect his reflection.

“Yeah?” Hank didn’t bother to try and hide the fact that he looked Bryan’s naked body up and down while the younger man dried off.

Bryan threw the towel over his shoulder and did the same to Hank. “Look at these fuckin’ pecs, dude!”

Hank shivered when Bryan’s huge hands reached up and grabbed the bulging slabs of muscle. Bryan’s hands running across his nipples, even through the shirt, was so intense his knees almost sagged. Being so close to the naked hunk hit Hank like a wave. He was acutely aware that Bryan’s thick cock dangled mere inches from his hand. When he found himself fighting the urge to reach out and grab it he turned away, crimson-faced. “I, uh, should get going. I’ve gotta go get some real clothes at my place before heading to the office. Tell Bill thanks for me. I’ll bring these back tonight.”

Hank’s mind was racing as he drove across town to his house. He felt fantastic, even better than he had the previous day, but he was more than a little confused. The increased arousal was something he could handle, but increased arousal towards other men wasn’t something he was ready to sign on for. The problem was compounded when, every time he tried to think about it, he instantly lost his concentration whenever he thought about Bill or Bryan or Josh. His anxiety about being so turned on by other men was always overwhelmed by the arousal itself, leaving him back at square one until he finally just gave up. He’d have to remember to bring it up with Josh later.

Hank sighed when he entered his house. By all standards it was gorgeous. For what he paid, it should have been. It was spacious and luxuriously furnished, but walking through it just felt lonely. The expensive trappings that used to make him feel superior now made him sad. The worn, stained couch at Josh’s house was suddenly infinitely preferable to his pristine leather sofa. His bedroom felt the same, and instead of being grateful to be home he just wanted to leave.

He hurried to change, pausing again to inspect his reflection when he’d stripped down to the tiny yellow briefs. He couldn’t bring himself to take those off. “Damn,” he whistled, flexing his pecs in the mirror. Bryan had been right to notice. It wasn’t just Bill’s shirt making them look bigger; they’d actually grown. He turned to the side and came to the same conclusion about his ass. This was confirmed when he finally forced himself to pull some pants on and found that he could barely get them on. They were precariously tight around his thighs and backside. His shirts were worse. Even his largest button-down wouldn’t close around his prominent chest. He opted for a polo, which made his enlarged pecs pop even more and showed off the size of his arms against the straining sleeves. He checked his reflection again, blushing at how tight the clothes were. He felt a swell of pride at just how much he filled them out, but the flip side of that was the knowledge that they left nothing to the imagination. When he walked the lines of his briefs were visible against the tight pants, and while the polo showed off his pecs nicely, he couldn’t do anything to get rid of the two lumps where his sensitive nipples strained against the fabric. “Can’t do anything about it right now,” he sighed, grabbing his gym bag. Remembering what happened the previous day he shoved a few extra shirts, blushing harder at the thought that he was taking cum rags to his office, and headed out the door, praying his clothes would make it.

His prayers went unanswered. Hank’s morning had been relatively uneventful. Just about everyone in the office commented on his appearance, either to harass him about shrinking his clothes or to compliment him on his apparent progress at the gym. He took them both in stride, enjoying that he was getting so much attention. Especially from his male colleagues and students, who he found increasingly captivating. He kept drifting off in his first class, finding it harder and harder to not be distracted by all the young men in the room. He still hovered by the podium, but unlike the day before, he made it through most of the class before finding it necessary to stay covered behind it. It didn’t seem like any of the students had noticed a change in his behavior, but Hank knew they eventually would if he couldn’t get a handle on things soon. He used the break between classes for relief. Locking himself in his office, Hank still couldn’t quite believe he was actually doing what he was doing. Bill’s briefs didn’t have a fly, and his pants were so tight that he was forced to pull both of them down for the access he needed. Standing hard and bare assed in his office, Hank tried not to think about what would happen if someone walked in while he quickly bucked his hips into one of the many spare rags he brought. Surprisingly, he fell into a routine. Class, jerk off, class, jerk off.

By his last afternoon class, Hank felt confident enough to venture farther from the podium. He was halfway through his lecture when disaster struck. While writing on the board in the front of the room, Hank twisted to reach for a marker when his pants finally gave out. There was a loud rip and a sudden breeze. It wasn’t a small rip, either. The entire back blew out, giving the whole class a clear view of the tiny yellow briefs barely concealing his growing cheeks. The room erupted into laughter as Hank quickly scampered back to the podium.

“That’s what I get for not dry cleaning these,” he laughed, trying to make a joke. He let the class go, but he was still forced to awkwardly scramble back to his office using his bag as best he could to cover the blown-out backside.

The walk back to his office had been painful. There was no way to fully cover himself, so he had to scamper back with his ass hanging mostly out. The few people he’d passed only snickered quietly to themselves, but Hank knew they had to be enjoying this. He had a reputation as “the hot professor” to begin with. He was all too happy to feed that reputation by using the student gym and wearing his form-fitting clothing, and he knew more than a few of his students and coworkers had thought about what was underneath his fitted pants. While he was happy to make people wonder, he was significantly less happy to answer their questions by exposing himself.

After enduring more ribbing from the office secretaries he once again found himself locked in his office. He kicked out of the shredded pants and leaned his head against the wall. He’d never felt more humiliated. Not only was he wearing another man’s much more revealing underwear, he’d just shown that underwear to an entire room full of grad students. That last part made him pause. Yes, he was mortified. But the more he thought about it, idea that he’d just shown his solid bubble to so many people started to turn him on. He pictured himself in front of the class, his sculpted body on display in just the tiny briefs with his solid cock tenting them out. The thought was horrifying and humiliating but he barely had time to pull down his briefs before cumming on the spot. His face burned as he watched the sticky fluid spray onto his office wall. He’d been so focused on his embarrassment that he hadn’t felt it building. Hank cleaned it up as best he could in a stunned haze, the shock bringing him a moment of clarity. He was a college professor. He had a Ph.D. He shouldn’t be jerking off in his office between classes. He shouldn’t be getting hard thinking about his male students. He shouldn’t be getting off on thoughts of debasing himself in front of people. He picked up his phone to call Josh and tell him he was done.

“Hey Prof, everything okay?”

“No! No, everything is very much not okay. I just blew out my pants in front of my entire class because my ass has gotten too big for my pants and I’m…”

“Whoa!” Josh cut him off. “You’re already seeing physical progress? That’s fantastic!”

“I…but I’m…” Hank’s sails abruptly lost wind. Just the sound of Josh’s voice had calmed him down, and now that he sounded so excited, Hank suddenly couldn’t bring himself to disappoint him. “I’m just not…there’s a lot going…” Hank tried, but physically couldn’t get the words out.

“Don’t worry, we’ll talk about everything tonight, okay?”

Hank missed the condescending tone in Josh’s voice. “I…okay…” he stammered, hanging up. Hank sat and stared at his phone, wondering why he’d been so worked up in the first place.

The rest of his day was filled with a growing excitement at the thought of going back to Josh’s house. He skipped the gym in favor of reluctantly buying some new work clothes. He hated the very idea of putting them on, but he knew he didn’t really have a choice since he was currently forced to wear the clothes he’d borrowed from Bill. Hank typically didn’t wear gym gear outside of the gym, and Bill’s was more revealing than what he was used to, but it just felt better. Part of him felt like he was too old to be traipsing around in bright, skimpy workout gear, but when he caught sight of his reflection he didn’t look like he was pushing 50. He was starting to look like he wasn’t even pushing 40.

When the time came to head to Josh’s he could barely contain himself. He practically bounded up the sidewalk from the driveway. All the reluctance and desire to quit he’d felt earlier had vanished.

“Hey!” he said, grinning from ear to ear when Josh opened the door. The lean young man just had on a pair of tiny running shorts and a baggy tank top. Hank’s smile grew when he saw the look of surprise on Josh’s face.

“Damn! Look at you!” Josh ushered him in, walking in a circle around Hank. “You weren’t kidding when you said you got bigger.”

“Hi Hank!” Bill came out from the kitchen, his hairy torso bulging out from underneath a purple muscle shirt while his lower half was only covered by a pair of bright red briefs. “Shit man, lookin’ good!” He joined Josh in looking Hank up and down.

“Let’s not stand around up here…let’s go get these measurements,” Josh said eagerly. Hank started stripping as soon as they got to the lab.

“I need to give these back to you anyway,” he said, tossing the shorts and t-shirt to Bill, who’d followed them down. “These, too,” Hank grinned, peeling the briefs down and throwing them over. It wasn’t until he felt his rigid cock bounce in the open air that he even thought about what he was doing.

“Still having the increased libido, I see,” Josh said as he started taking measurements.

“You can say that again,” Hank sighed. He felt himself blushing while he stood exposed and hard under Josh and Bill’s gaze. The awkwardness he felt only turned him on more. “Did, uh, this happen to you too,” he asked Bill sheepishly.

“Oh yeah,” Bill nodded. “Best to just deal with it and move on.” To that end, Josh handed Hank a wad of paper towel.

“What am…oh!” Hank’s face burned harder when he realized what Josh meant for him to do. “This is…uh…a little weird…” he stammered. It never occurred to him to say no, or to at least ask for some privacy. While Josh measured and Bill watched, Hank reached down and started tugging. He’d never done anything like this in his life. He’d never jerked off in front of anyone before, not even former kinky girlfriends. Fortunately, he didn’t have long to think about what he was doing before he was holding a damp, sticky wad of paper.

“There you go, big guy,” Bill said cheerfully. “Feels way better, yeah?”

“Does it, uh, always happen that fast?”

“Your stamina will increase, that’s just a current side effect,” Josh cut in. “Well, you’ve definitely started growing. Your chest and backside are both noticeably larger, as are your thighs and arms. Your waist has gone down a bit, with your abs starting to show, and I can see that your hair has started filling in on your head, but seems to have vanished everywhere else.” Josh looked him up and down again. “Other than the libido, still feeling good?”

Hank nodded eagerly. “Yep!”

“Okay, then you know the drill.” Hank did his turn in front of the camera and let Josh stick him with the needle. “There we go.”

Bill came over to Hank while Josh put his equipment away. “So you sticking around again?”

“Uh, yeah, sure, if that’s cool,” Hank said, hoping he didn’t sound desperate.

“Dude, of course it is! We like having you around.”

Hank’s stomach fluttered at the compliment. “I like being here!” He started to follow Bill upstairs, but froze. The hairy younger man was still holding Hank’s discarded clothing, leaving him with nothing on. “Uh, whoops,” he laughed. “I, uh, didn’t bring any other…”

Bill grinned and shook his head. “Come on,” he said, giving Hank’s bare ass a swat, “we’ll get you fixed up with something fresh.”

For the second time that day, Hank sauntered naked through the house as he followed Bill upstairs to his small, sparsely furnished room. There was a double bed in one corner and a dresser with a TV on it across the room. It was worlds away from Hank’s bedroom, but he didn’t want to be anywhere else.

“All right, let’s see what we’ve got,” Bill said, taking his time while he dug through his dresser. He would occasionally look over his shoulder at Hank with a mischievous grin. “These should work.”

Hank caught the small wad of thin lavender fabric and blushed. He’d never worn anything like them. The pouch was just barely big enough to hold him, and the thin fabric outlined his package to the point where it might as well have been see-through. Aside from that, there was a small patch of fabric in back that left more of his ass exposed than covered. “I think you got ripped off,” Hank laughed bashfully. “They didn’t sell you a whole pair of underwear.”

“Beggars can’t be choosers,” Bill said smugly, clapping him on the shoulder. “So Bryan’s out and Josh is going to have his nose in a book all night…wanna just kick it up here?” Hank nodded quickly. He didn’t care what they did, just so long as he was there. “Cool, we can bring some beers up here and watch a movie or something.”

“I’ll grab ‘em,” Hank said, eager to contribute. He hurried back down the hallway, noticing for the first time how much his larger cheeks bounced as he skipped down the stairs. On the way back he stopped in the bathroom to check out his reflection. His heart raced a little at the memory of where a naked Bryan had stood that morning. It raced even more at what he saw. Hank was stunned. He barely recognized himself. His formerly thin blonde hair was now thick and full, and noticeably lighter. His features had continued to soften, losing nearly all of his wrinkles by this point and making him look at least a decade younger. The changes from the neck down were just as impressive. His pecs weren’t just more defined, they were bigger and were standing up off his body, forming a shelf of muscle between his wide, broad shoulders. He understood why his shirt fit the way it did when he saw that his nipples had puffed into two hard, prominent nubs. Beneath this, his increasingly ripped stomach tapered inwards before blowing outwards again at his ass and solid thighs. Hank couldn’t believe it. He looked less like an academic and more like a professional bodybuilder. He kicked himself for ever thinking that he should have stopped this. He was still grinning when he got back to Bill’s room.

“Check yourself out on the way back? I know that look.” Bill grabbed a beer and flopped down on his bed. He patted the spot next to him and Hank dropped down.

“This is just…I mean…wow…” Hank stammered.

“I remember how it felt when it first started working for me. I don’t know how Josh did it, but I’m sure glad he did.” Hank nodded in agreement. He was too focused on how close he and Bill’s bare legs were to each other to say anything.

Bill put on a movie while they drank and talked. Bill did most of the talking. Like the night before, Hank felt himself relaxing just being around the other man. His firm voice made Hank feel safe and content. Hank wasn’t used to letting other guys be in control around him, and he wasn’t prepared for how disarming that feeling was. He followed the conversation as best he could, but soon he started drifting off.

“Huh?” Hank opened his eyes and jerked upright. He was still leaning against Bill’s wall, but he’d clearly fallen asleep at some point. “Oh, shit, sorry…”

“Guess I’m not exciting company?”

“No! It’s not that!” Hank said quickly, feeling terrible at the thought of Bill being disappointed in him. “It was just a long day and…”

“Whoa, whoa,” Bill laughed. “I’m just fuckin’ with ya. I’m wiped too.” He got up and turned the TV off, stripping out of his muscle shirt before he hit the light. Before Hank could say anything Bill was clambering back in bed. “Figure this is more comfy than the couch downstairs, unless you want that?”

“No, no, this is fine,” Hank said, thrilled at spending another night, and even more excited to be doing it in Bill’s bed.

“Good!” Without saying anything else, Bill draped an arm over Hank and settled in. “You mind being the little spoon?”

At their size, there was no way they could comfortably share the double bed without being on top of each other. Hank wasn’t usually one for cuddling. He liked having his king bed to himself. Or so he thought. Now, shifting around and nestling back against Bill, there was nowhere he’d rather be. The other man’s furry chest was soft against his back and Bill’s wiry leg hairs prickled Hank’s now-smooth thighs as their legs tangled together. Hank’s mostly exposed ass made a perfect resting place for Bill’s stout, meaty package, and there was nothing he could do but press back against it. What he enjoyed most, though, was the strong, heavy arm that Bill had thrown over him, holding him close against the hot breath on his neck.

“G’night dude,” Bill yawned.

“Night,” Hank said, lying in the dark and basking in the strange new feelings.

Hank and Bill shifted during the night. When Hank woke up, Bill was on his back and he was draped across the other man. Hank had his face nestled against Bill’s neck with an arm thrown across the other man’s hairy chest. Hank’s leg was draped on top of Bill’s and he could feel his solid cock digging into the other man’s side.

Hank didn’t move. He watched Bill sleep, feeling the rhythm of his beefy chest rising and falling under his arm. He loved the way the other man’s pouty lips looked against the rough stubble on his cheeks and started to wonder what they’d feel like against his own. His cock twitched at the thought and he noticed Bill’s equally hard member had escaped the confines of his briefs. Hank stared at the wide, thick organ, licking his lips. He was moving before he even realized. Trying not to wake Bill, he slid down as gently as he could. He was surprised that he didn’t even hesitate. He dropped his face, relishing the way the warm, solid pole filled his mouth and felt against his tongue. He quickly fell into a rhythm, his head bobbing up and down while his lips formed a vacuum seal.

“Mmm…good morning to you too,” Bill laughed sleepily, running a hand through Hank’s hair.

Hank froze and looked up to see Bill smiling down at him. “Sorry…oh man…I don’t know why I did…”

“Dude, I wasn’t complaining,” Bill said, folding his meaty arms behind his head. “You’re doing great.”

Instead of questioning his behavior, Hank was eager to get back to it. Now that Bill was awake he pulled the other man’s underwear free entirely, running his tongue over the heavy, hairy balls before swallowing the glistening cock again. Hank imagined what he must look like: his tiny waist squirming, wagging his round, even larger ass that stuck up in the air while the muscles of his broad back rippled and flexed with his bobbing motion. The thought of himself, the accomplished, older professor, moaning like a dog in heat around the oozing dick wedged in his mouth, eagerly drinking in the musky, sweaty smell of the young man was humiliating. This wasn’t how things usually went for him, and not just because he was blowing a man for the first time. Hank knew he wasn’t the one in control. He didn’t even want to be the one in control. He writhed and grunted, wedging his tongue in every crease and crevice of Bill’s crotch, the knowledge that he would do whatever Bill wanted, no matter how debasing, driving him on harder.

“Fffffffuuuuuuuuu……” Hank was so worked he up he only dimly heard Bill’s strained grunt before his mouth was suddenly full of a warm, salty liquid. He swallowed as much of it as he could, but the bulk caught him by surprise and went running down his chin. “Not bad,” Bill panted with a cocky grin.

Hank sat back on his knees and stared down at Bill’s burly, hairy frame with still-hungry eyes. He could feel the young man’s cum running down his neck to the pecs that, he noticed for the first time that morning, bulged even further than the day before. While Bill’s wide, thick cock softened across one of his furry thighs, Hank’s stood achingly hard. “Did I do okay,” he asked bashfully.

Bill motioned for him to lay back down. “Lose these,” he said, snapping the waist of Hank’s skimpy underwear. Hank eagerly hoisted his thickened thighs into the air and pulled them free while Bill stroked the underside of his smooth, meaty leg. Without saying anything the younger man reached down and grabbed Hank’s throbbing pole.

“Uuuuuuuhhhh!” Hank groaned at the touch, a spasm running through his whole body. Bill kept his gaze locked with a condescending grin while he stroked Hank’s cock and tugged roughly on his balls. It was less romance and more like he was being milked, but Hank loved it. He couldn’t look away from Bill’s handsome, stubbled face with its smug expression. He knew his own face was wide-eyed and desperate while he whimpered pathetically until he came. At first all Hank could do was gasp wordlessly while the world around him seemed to explode, but his silent gaping was quickly replaced by a shrill shriek as he unleashed a raging torrent all over himself. Bill angled his cock so that the deluge splashed all over his huge new chest and face. Hank was mortified at the sounds he was making while being soaked by the sticky rain, but still he couldn’t look away from the young stud next to him. “Oh…oh god…” he panted.

“Geeeeez…sounded like someone was getting murdered in here.” Hank discovered that it was possible to feel even more humiliated when he craned his neck and saw Bryan and Josh standing in the doorway. He was naked and covered in cum in front of the entire house, but instead of trying to cover himself all he could do was stare at Josh’s lean, ripped body in nothing but his tiny underwear while Bryan was just naked behind him.

“So…sorry,” Hank said, sitting up and immediately regretting it. He turned a deep shade of purple as it felt like he was getting slimed all over again when the fluid ran down his torso.

“Holy shit, man!” Bryan pushed past Josh and came over to the bed, his semi-hard cock wagging inches from Hank’s face. “You look great!”

Hank was pulled to his feet and he could see his reflection in the mirror on Bill’s dresser. He didn’t even recognize himself. He looked like he was barely out of his twenties. His once-thinning dirty blonde hair was now a shaggy, platinum mop. His prominent, hawkish nose had started to resemble more of a button than a beak, and his thin, stern lips were noticeably puffier. And they weren’t the only thing that had inflated overnight. Hank’s chest had continued to change, turning his ripped pecs into a matched set of solid, juicy mounds of muscle with large, firm nipples. The rounded slabs competed for space so much that he could barely bring his hands together in front of himself, and they looked impossibly large above a waist that had pulled further inwards. Top heavy as he was, Hank was in no danger of toppling over as the tiny waist was supported by a set of wide, inviting thighs and a now-mammoth ass. Like his impossible chest, the huge, round cheeks constantly fought with each other for space, shifting and flexing with the slightest step. He couldn’t see his softened cock over the bulging shelf that was his chest, but in the mirror Hank watched his cock settle into a long, semi-hard banana hang. “What…holy shit…” He watched his thickly muscled arms inflate while he prodded himself, not sure what to think. Despite all his ample new muscle, Hank felt far from masculine. Bryan and Bill, even Josh’s smaller but ripped frame, looked athletic and powerful. Their muscle looked functional and broken in. Hank’s was starting to look less so.

“Look at this fuckin’ chest!” Bryan came around behind Hank and reached up under his arms to grab the new lumps of muscle.

“Whoooaaa!” Hank spasmed when an electric shock ran through him, causing him to shove his bare, ballooning cheeks back against Bryan’s cock. The feeling of the other man’s thick hose wedging between them sent another powerful jolt through him. Bryan didn’t let go, which caused Hank to squirm even more and more as he felt Bryan’s cock starting to harden between his solid globes. He gasped, wide-eyed, at Josh and Bill, but they made no move to intervene. Hank kept squirming, unsure if he was trying to pull away or work Bryan in deeper. The other man was fully hard now, and was even moving his hips in time to Hank’s squirming. It happened so fast Hank barely registered it. He’d leaned forward, pressing against the firm grip Bryan still had on his sensitive new chest when he felt a quick, sharp stabbing. When he squirmed again he was hit with a wave of pleasure so intense his knees buckled. The sculpted young man was inside him.

It was like nothing he’d ever felt before. Whatever changes were happening to his body made him a natural bottom. His virgin ass should have felt like it was being torn apart, but the occasional pain that he felt only made the pleasure more intense. And unlike when he’d just blown Bill, he didn’t have to imagine what he looked like. He watched his shocked, crimson expression panting and gasping in the mirror while he writhed on Bryan’s dick. “GGGnnnnnnnnnn!” Hank grunted and came, spraying all over Bill’s dresser. The speed and the amount with which he came wasn’t helping Hank feel more masculine or in control, and every time it happened he felt like a bit more of himself slipped away. A few minutes later he came again and felt the same hammer blow to his old self. The confident, arrogant Hank was gradually being whittled down to a horny, eager fuck boy. When Bryan gave a final thrust and filled his insides, Hank was actually disappointed.

Instead of being furious about the semi-consensual fucking he’d just received, Hank blushed and looked at the sticky mess he’d made. Bryan’s cum was dripping down his legs, making his face burn even harder. “Uh…sorry about the mess…” he said bashfully, scratching at his thickened scalp. He could feel that he needed to say more. It felt important. There was something just under the surface that he couldn’t get out. Under the smug, arrogant gazes of Bill, Bryan and Josh he could hardly focus.

“Whatever man,” Bill said, finally climbing off the bed and slapping one of Hank’s sore cheeks. “You can clean it up later.”

Hank had already missed his first class by the time he finally drug himself out of the guys’ house. He’d squeezed himself into the new clothes he’d bought the day before and hurried out in a daze. Hank was glad he’d gone shopping because even the larger clothes he’d bought were stretched tight across his changing frame. He had to leave the top button of his shirt undone and the sleeves barely held together around his huge biceps. His pants were even tighter, creeping between and accentuating the beachball-sized ass, but they didn’t feel like they’d give in.

Hank tried to process what had happened that morning, but any thoughts of the guys quickly devolved into distracting fantasy. And he was having a hard enough time keeping it together as it was. He had to double-check the schedule on his phone to even remember what class he was about to teach. He wouldn’t have time to go to his office first, so he hoped he could hold out.

“Good morning, everyone, sorry I’m late,” he said, scurrying into the room a few minutes after class should have started. He dug through his bag to pull his materials out with his back to the class, oblivious to the quiet gasps that spread throughout the lecture hall. He was so focused on remembering the points of his lecture that he also missed the subtle phones being pulled out to snap his picture.

The class didn’t go well. Hank kept trailing off mid-sentence, losing his place. Material that he’d taught hundreds of times no longer made sense, and every time he looked out at the class their stunned expressions only made it worse.

A voice from the hallway saved him. “Okay folks, let’s call this class early.” Hank was relieved to see his fellow professor Ted come swiftly into the room. They weren’t exactly friends, but they’d hit the gym or the golf course together on occasion. Hank was just glad to be bailed out. “You’ve all got a syllabus, so you know what chapters to work on. Professor Fitzgerald isn’t feeling so great today, clearly,” Ted said, positioning himself in front of Hank until the students were gone. He went over and shut the door, his face furious when he turned back around. “What the fuck is wrong with you, Hank? What is this?! I barely recognized you.” Ted kept looking Hank up and down in disbelief. “Did you lose some kind of weird bet? I know how you are about the gym, is this a steroid thing?”

Hank didn’t understand why Ted was so furious. “I just…I don’t know why I couldn’t figure out the lesson…”

“The lesson?! Christ man, that’s the least of your problems!” Ted pulled out his phone, his face going pale. “Goddamn students already have it all over the internet.” Ted held out the phone and Hank’s stomach dropped at what he saw. His clothes didn’t exactly fit after all. It wasn’t just his top button that was open, but almost the entire top half, leaving a large swath of his meaty new chest on display, with his enlarged nipples sticking out obviously underneath where the shirt managed to cover. Worse, though, was the long, obviously hard and clearly outlined cock straining against his skin-tight pants that didn’t even cover all of his rotund behind. The top of his globes, barely covered by the tiny lavender underwear, hung out above the waist of his pants while the back of his shirt rode on top like his cheeks were a shelf. He’d been walking around rock-hard with his ass hanging out and hadn’t even noticed. “Tenure or not, you could lose your job over this,” Ted said grimly.

“Ted…I…I don’t know what I’m doing…I…” Hank wanted to tell him about Josh and the supplements but he couldn’t get the words out. He was too stunned by what he saw on the phone. Not only did he look a few decades younger than someone his own age, he looked nothing like a professor. He was a doe-eyed, overly built, hyper-sexed freak. The shock of the situation and his distance from the guys was enough to let him see himself clearly. His exaggerated proportions weren’t anything close to what he’d ever want. The solid, athletic body he’d worked so hard to maintain had been replaced by a disproportioned gym bunny twink who only sculpted very specific parts of himself. His ass wasn’t just prominent, it was obscenely huge. Watching one of the videos that had already been posted, he hadn’t noticed the new waddle to his step or the awkward angle at which his thick arms hung. He had to get Josh to fix this.

Before Hank could say anything else, Ted ushered him towards the door. “Look, Hank, you need to get out of here. Now.” Ted looked out to make sure the hallway was mostly empty. “Before the classes let out. I don’t know what’s going on with you, but laying low is your best bet. Go to a doctor. Say you’re going to rehab. Anything that will give you an excuse for this. Crazy is better than…” Ted trailed off, shaking his head. “Go!”

Hank ran, or at least scampered the best he could with his awkward new lower half. He tried to ignore the way it made his pants rub against his still painfully hard dick or the way the air felt on his increasingly exposed ass. He had to hold his pants up as the bouncing motion finally caused them to drop below the crest of his ample mounds. It looked less like he was running and more like he was twerking his way forward. He squirmed out of them when he got in the car, unable to stand how confining they felt on his legs. It took all of his concentration to drive to the house. He was determined not to let his focus slip, no matter how much his cock begged for attention. Still without pants, he bounded up the drive and let himself in, oblivious to the people passing on the sidewalk out front. The instant he saw Josh in the kitchen he felt his resolve slip.

“Whoa!” Josh’s grin, sinister now, still melted Hank on the spot. Josh walked over and looked Hank up and down slowly. Hank’s long hose had escaped from the small underwear and bobbed freely, while his top-heavy torso bulged half out of the button-up shirt. “What happened to you?” Josh laughed.

“You know what happened!” Hank managed to at least raise his voice. “What did you do to me?”

Josh was calm, his firm, thin fingers slowly undoing Hank’s remaining buttons. “Only what you wanted.”

“I didn’t want this! I’d never want this!”

“Oh, come on. Look at you. You’re young and hung,” Josh said, squeezing Hank’s oozing rod.

Hank fought to maintain what little control he had. “You…you turned me into a freak!”

“You might think so. Someone else might think you’re perfect.” Josh pulled the shirt free and tossed it aside. “Okay, I’ll admit, I wasn’t completely honest with you. I’ve already completed the original supplement. That’s what Bill and Bryan were for. But don’t get jealous. They started as partners, but then I asked myself why would I want to share my profits when instead I could just have two dumb horny beefcakes who’d do whatever I said?” Josh’s smile was as triumphant as it was evil. “They’re not still in classes here. I just had them pretend so you wouldn’t get too suspicious too quick. I didn’t know how long it would take before you crossed over. Imagine my surprise when you agreed right away. Remember that water bottle I gave you in the gym the other day? It had a formula in it to make you more agreeable, but I had no idea if it would actually work or not.”

Hank felt a flash of rage. All of the confusion he’d been feeling over why he’d agreed to any of this made sense. He’d been drugged from the start.

“Given the exaggerated nature of your changes I expected a last breakthrough right before the end. I honestly thought it would’ve been this morning with the pounding Bryan gave you, but I can see how exposing yourself to an entire class would do it. I already saw the video,” Josh said, patting Hank on the shoulder as he continued. “No, with you I was interested in something more…specific. You’d be surprised how much of a market there is for putting someone in your position. Can you imagine? Corporate rival? Slip them a few doses and you’ve got a slutty little moron to do with as you please. What’s more, no one would even recognize them.” Josh circled behind and wrapped his arms around Hank’s thin waist, resting his chin on a broad shoulder. “Hell, someone could even weaponize it. That would be interesting. Slip it to an enemy army? Or an unsuspecting city?” Josh dug his crotch against and Hank’s ass and laughed at the whimper the other man tried to suppress.

“O…okay…” Hank said through gritted teeth. He wanted so badly to pull away. “Now that you know it works you can undo this.” He winced when Josh’s hands drifted down to palm each of his enormous cheeks. He could feel himself slipping.

“Sorry, Prof. This is a one-way trip.”

“You can’t leave me like this!” Hank wanted to sound commanding but came off as desperate.

“I’m not going to leave you like this.” Josh laughed when he felt Hank tense as the unseen needle stuck his backside. “That was the last dose, but you’ve got enough serum in you that it’ll probably be a couple of weeks before everything settles into place. Don’t worry, when it’s all said and done you won’t care about much at all. This formula enhances the important parts, like pleasure responses and how to use this new body of yours to its fullest…” Hank squealed when Josh pinched his enlarged nipples and his whole body spasmed, “…and gets rid of all that other stuff like memory and critical thinking and aggression.”

Hank started shaking in Josh’s grip at the thought of what was coming. His difficulty focusing, his inability to remember the lesson earlier; all of it was just going to get worse. “No! You…you can’t!”

“Don’t worry,” Josh said gently, stroking Hank’s ripped stomach. “You’re not going to be a vegetable or anything. I mean, Bryan and Bill got dumbed down from where they started too. Granted, they’re most likely going to look like geniuses compared to you, but we’ll take care of you.” Josh spun him around to face Bill and Bryan who were waiting on the stairs. Hank searched their faces for any hint of help, but all he saw was his own intense lust reflected back at him. He looked towards the front door. He could make it. There was nothing stopping him. All he had to do was walk through it. Hank felt a surge of hope as he started walking towards it, but that only lasted a few steps. Instead of walking through the door he turned and let the two men take him upstairs.

“Ooooohhhhh! click here!” Hank’s lustful wailing drowned out the sound of the bed frame slamming against the wall as he bounced up and down. He was on his knees, his smooth, meaty legs straddling Josh while he bounced his giant ass, impaling himself on Josh’s long, solid pole. Hank’s ample biceps flexed as he ran his hands ecstatically through his shaggy platinum hair or across his bouncing, bulging pecs. His oozing cock slapped against Josh’s abs over and over with the motion while Hank gazed longingly down at the lean hunk between his legs.

Josh’s original assessment had been fairly accurate. It had taken another three weeks for the serum to fully absorb. The first few days after the final injection had been a nightmare for Hank. He was still coherent enough to know what was happening, but too far gone to do anything about it. He’d spent the next two days completely out of control, constantly bouncing between the three of them in a lustful haze. While his body was in overdrive, his brain was slowing down exponentially. By the third day he couldn’t hold a coherent thought for more than a few minutes at a time, and he was developing a goldfish memory. By the end of the day, he could barely remember how it started. He still had his long-term memories, but even those were quickly filling with holes. Even if he’d been able to escape, he had no idea how to get to his house anymore. Laying on top of Bryan or Bill in a small room on a tiny, cum-stained mattress he could still remember his giant king-sized bed. He just couldn’t remember where it was. And calling for help was out of the question. The one time he’d been left alone by a phone, he didn’t know what any of the buttons meant. He knew he should know, but the symbols on the screen didn’t have any meaning. It was the same when he looked at pieces of paper in the house. He knew he should know what the markings meant, but he was clueless. Every time it happened he would start to panic. His stomach would drop and his heart would start racing, but after a few minutes he couldn’t remember why he was upset. And by the end of the first week, even that stopped. Hank still remembered that he had a life before all this, but it took a herculean effort to recall any details.

If he was left alone in front of a mirror long enough he could start to remember. The barely 21 year old staring back at him would start to look like a misshapen stranger. His shaggy hair, the dimly innocent, doe eyes and button nose, the full, flushed cheeks and puffy lips all looked wrong. His broad shoulders and round, juicy pecs shouldn’t have been as big as they were. His waist shouldn’t have been so tiny. His ass shouldn’t be that size; no one’s should. And the long, ample cock dangling between his legs shouldn’t always be so close to hard. He knew no one else was shaped like him, at least not outside of drawings he’d seen in some of Josh’s books. Hank would always just end up confused. He didn’t understand why it felt wrong if it made the other guys so happy. He wanted them to be happy. He needed them to be happy.

By the end of the second week that was what occupied the few fleeting thoughts he’d have during the day. All he wanted was to please the guys, Josh especially. He couldn’t do much to help out around the house because of how easily he got confused, but he could do simple things. He liked to work outside, but they yelled if he went out without at least putting some underwear on. Hank didn’t like that part, but he did like the way people looked at him when they saw him outside. Josh took lots of pictures of him, too, and said that helped. He’d dance or flex for the camera, and Josh would film him and the other guys all the time. He said people paid a lot of money to watch, which would make Hank happy, even though he didn’t have much of a concept for what a lot of money was anymore. By the end of the third week Hank no longer had any idea of how much time had passed. His days existed largely independent of each other. He could spend one day with his face buried in Bill’s ass, tongue bathing every inch of the hairy behind, and eagerly do it again the next day.

After a month had gone by, not that Hank knew, Josh started taking him out of the house. Hank didn’t like it, but if Josh wanted him to, he’d do it. He had to wear clothes, which he rarely did anymore, and driving through town made him start to feel the same panic he used to feel. Not that he could explain it. For someone who used to deliver lectures, Hank’s vocabulary had diminished considerably. The best Hank could do was say he didn’t like how it felt. They usually wound up in some old building where Josh would talk to some other people and make him take his clothes off. Hank liked the way the other people would check him out and touch him. He didn’t understand a lot of what was said, but the other people usually seemed happy to look at him. Josh also brought his computer, and he’d show videos of an older naked guy. Hank thought the guy was super manly and hot, and the other people must have too because they were always surprised to see whoever it was. But sometimes when Hank looked at him he felt funny, like he knew who it was. He’d seen pictures of the man before when some angry looking people had come around the house asking questions about someone. Hank couldn’t follow most of it, and they didn’t seem to like his lack of clothes as much as he did. They came around a few times to ask about the old guy going missing, and all Hank knew was at some point they stopped coming around. Josh said he took care of it, so Hank didn’t worry.

The one thing Hank did like about the outings was that Josh would give him a treat when they got back. The current bouncing he was doing on top of the other man was a reward for just such an outing.

“Don’t…forget….” Josh said as Hank’s bouncing increased. As soon as he said it, Hank grabbed the end of his flopping dick just in time for a steady flow of cum to ooze out between his fingers. “Good job,” Josh said like he was talking to a dog who just rolled over. Hank kept bouncing, rubbing his cum soaked hand all over his chest. He knew Josh didn’t like it when he sprayed all over him. Hank didn’t understand that. He loved it when the guys would do that to him, but if Josh didn’t like it, he wouldn’t do it. He kept bouncing, his insatiable lust barely lessened. Josh still hadn’t cum, so he had to keep going.

“Mmmmmmmmmmmmmm….!” Hank arched his back and purred when he felt Josh unload inside him. He grabbed the cock with his dexterous hole and made sure to squeeze every drop out, loving how it felt. “That was fun!” Hank beamed down at Josh, who was now the older of the two by almost ten years.

“It sure was,” Josh panted, pulling Hank down on top of him and kissing him roughly. The addled blonde had no way of knowing how much Josh loved their new dynamic. It wasn’t just Hank’s impossible new body and eager attitude, either. Josh had already made deals with half a dozen clients for more money than most people could even imagine. “Hey, tomorrow night you and the other guys are going to go meet with some new people who are having a party. They saw your guys’ pictures and wanted you to come.” Josh laughed and kissed Hank’s button nose at the other man’s sour expression. “It’s not like the meeting tonight. You guys are going to have fun. You won’t have to wear anything.”

That was all Hank needed to hear. “Good! I hate it when I have to. It feels weird.”

Josh grinned, thinking about how the old Hank would have reacted to being told he was going to be whored out at a party. He reached down and bounced Hank’s still-solid cock before throwing his legs over the edge of the bed. “All right…why don’t you go play with Bill? I’ve gotta get some work done from the meeting tonight.”

“Okay!” Josh was shaken on the rebounding mattress as Hank eagerly bounded out of bed. The now-young blonde hurried down the hall like an excited puppy, already forgetting what Josh had just told him. He knew it didn’t matter. He trusted the other guys to take care of him.

“You finally wear Josh out?” Bill and Bryan were in Bill’s room, sprawled out on his bed in a pile of sculpted muscle.

“Yep!” Hank said proudly.

“Good job!” Bryan and Bill exchanged glances. “So, is it our turn?”
