Unintended transformation

by Mr. Muscle lover

Doug is a nerdy 32-year-old accountant who is desperate for sex. He finds a website selling a secret formula that leads him down a path of unexpected change and insane growth.

Doug had just reached the age of 32. He was in pretty good physical condition due to his love of CrossFit and had an athletic build. He was Asian with short black hair and glasses which made him look a bit nerdy. The years of CrossFit had not seemed to change that, and his poor vision demanded some thick glasses which did not help with his nerdy aesthetic.

Doug considered himself to be 100% gay always lusting after the hot guys in his CrossFit class. He loved to steal glances at them as they got sweaty from working out. Watching their clothes get wet and showcase their bulging muscles was a major turn-on for him. A few of the more confident guys would even take off their shirts, showing off their big, meaty pecs. It gave him almost unlimited jerk-off material, and he would often pleasure himself to the images of the guys after his CrossFit classes.

Along with his nerdy Asian aesthetic he also had a smaller manhood, with it only measuring a tad over five inches. He was very self-conscious about it, especially in the gay community. All of the guys in his CrossFit class also seemed to have large bulging packages, which did not help with his self-esteem. He liked bottoming, though, and had a large collection of dildos, with one measuring almost 12 inches. He figured his ticket to hooking up with a hot guy would be to power-bottom. Unfortunately, years of messaging these guys on Grindr had resulted in no responses. He could occasionally get a hookup with a less desirable, out-of-shape guy, but it was always very unsatisfying especially when he lusted after muscles.

He started to do some online research; maybe if he could get bigger muscles and look more like a bodybuilder he could attract some more hot guys. He first looked at some steroid sites, but the side effects seemed scary to him, so he quickly moved past that. He eventually stumbled upon a website that looked very dated. It was probably from the beginning of the internet with its basic design. The main page read, “Looking to fulfill your desires? Try one of our packages today. One small injection will give you the results you could only dream of.” The site was otherwise plain; he had expected it to be filled with before-and-after testimonials like many of the other sites selling you crap. The simplicity intrigued him. So, he placed an order; surprisingly, it was only $100. He figured at the very least it would be a good jerk-off fantasy. He then jumped on to his favorite muscle growth site and jerked off to some hot guys before going to bed.

He woke up the next morning to a notification that the package had arrived. He was surprised at how quick it was. He was currently on a staycation, so he had the next two weeks off to relax. He got dressed and walked around his condo. His accounting career has been going well, so he had a large condo with high ceilings and his own workout room with a squat rack and tons of weights.

He put on some clothes and then went down to the concierge desk to sign for the package. He then raced upstairs eager with the anticipation. As he got back into his condo, he opened the package and found two syringes. One red and one blue. There was also a small booklet with a ton of detailed writing in it he could barely read. He was starting to get extremely horny at the thought of what the syringes could do, so he decided to just grab the red one and inject it. He had a bad habit of throwing caution to the wind when he was aroused. He waited for several minutes, expecting something to happen like in one of the erotic fantasies he read where all his muscles would explode in size. Unfortunately, nothing occurred; he quickly jerked his cock at the thought, though, and shot a big load into his hand. He cleaned up, then placed the package into a drawer, resigned to the fact that it was probably a scam and that he just injected himself with colored water like an idiot.

The rest of the day was uneventful with him running some errands and attending a few appointments. He got back somewhat late, so he just headed straight to bed.

The next morning, he woke up to a painful erection, like he had not cum in several weeks. He had to jerk off three times before it finally subsided. He made himself some breakfast and was surprisingly hungry, so he had several large bowls of oatmeal and some protein shakes. After all the food he felt extremely energized, so he decided to attend a CrossFit class. He quickly ran there, arriving just in time for the eight a.m. class.

He noticed right away that several of the hot guys he had lusted after were in the class today. He quietly made his way to the back. He pushed through the workout with relative ease. He was able to increase the weight on all his kettlebell exercises and the split jerks. He kept glancing over at some of the hot guys who had begun to get sweaty and take their shirts off. Strangely, his eyes lingered on their amazing round asses. He had never been much of a butt guy, but the way some of them were moving was getting him hard. He loved watching the guys in short shorts doing squats and seeing the shorts ride up showing the details of their muscular asses.

He quickly left after the fitness class; he was feeling extremely horny, so he raced home. He decided to take the stairs up the 15 floors since he did not want to wait for the elevator. He lunged up them quickly and then burst into his condo. His erection was aching again like this morning and he proceeded to jack off several times standing in the living room, shooting a big load all over the floor. He cleaned up the mess and surprisingly still felt energized, so he decided to go to his home gym.

He walked into the gym room and decided to continue with legs since they were already warmed up. He loaded up his squat rack with four 45-pound plates and started to do some slow squats straight to the ground. He knocked out 12 with ease—which was surprising, since this was currently his max weight. He added two more 45-pound plates and began his next set. This one felt a lot more intense with him having to push hard after the 4th rep. On the 6th rep he felt like he should stop, but his dick started to get hard again, so he kept on pushing. Each rep he completed felt orgasmic as he could feel his legs growing and his shorts getting tighter. He got to rep 13 and as he finished it his dick started to spasm as he orgasmed in his shorts from the intensity. He looked at himself in the mirror and could see his legs looking pumped to the max, and there was a huge wet spot on his shorts.

He continued to do squats for the next several hours slowly progressing up to four 45-pound plates. He finally decided to stop for some food and looked down at the puddle of cum that was on the floor and dripping down his leg from his shorts. It was strangely erotic.

He cleaned up the mess and then headed to the kitchen. He made a huge meal of chicken and rice and started to chow down. As he is eating, he remembered the box. There was definitely something in that injection, he thought. He opened the box and started to read through the pamphlet; soon he got to the portion about what each vial would do. The blue one labeled “the ultimate bottom” encouraged muscle growth, ass growth, and increased libido, and allowed the user to take extremely large penises. The red one labeled “the power top” encouraged muscle growth, dick growth, hyper-libido, hyper-cum production, and height growth. It also noted that only one injection could be taken, since the two would cancel each other out if both were taken. There was also no way to reverse an injection once taken. Two vials were sent to ensure that the person taking the “the power top” injection had a suitable bottom available, since un-injected men would likely not be able to handle them.

He felt a bit of panic after reading the last sentence. It was hard enough to get anyone to hook up with him when he was bottoming; there was no way in hell anyone was going to let him top. His mind started to race, but he calmed himself and decided to head to bed. It had been a long day, and he was pretty tired from all the training. He would think about what to do in the morning.

He awoke the next morning with another painful erection as his dick throbbed and stuck straight in the air. He rubbed his eyes and put on his glasses and was shocked at the size of his penis. He removed the sheet to reveal a large throbbing eight-inch cock that was quite thick. He reached over to grab it to assure himself it was real, and one modest stroke caused him to shoot a massive load all over himself. He was so horny he just kept jerking through the post-orgasm sensitivity shooting several more loads all over himself. He got up and stumbled to the bathroom. As he glanced in the mirror he was shocked by his reflection; looking back at him was not his usual athletic, nerdy self. Instead, there was a jacked-looking bodybuilder with a huge dick. The image of it caused him to orgasm again, shooting several ropes of cum over the mirror. He wanted to go shower, but his dick would not relent. He kept thinking of the hot guys’ asses at his fitness class and how much he wanted to fuck them.

He decided that he needed to fuck someone as soon as possible. With a body and a cock like this he should be able to find someone. He took a few new pics showing off his new assets and then hopped on Grindr. His torso pic got him plenty of messages, and he was able to find a hot muscular Latino man that wanted to come over right away. He would normally have gotten dressed and entertained the person, but he decided against that since he wanted to skip the small talk and get to fucking since his dick was beginning to ache again.

He heard a knock at the door about 20 minutes later. He put a towel around his waist and answered the door shirtless with a clearly visible erection through the towel. The man was super sexy and looked better than his pics. Upon seeing Doug in his aroused state, he immediately stripped off his clothes, and they started making out. The Latino man then bent down and started to suck on Doug’s dick; he was struggling a bit with the size and was only able to get the head in his mouth. Doug then guided them to the bedroom, eager for the action to start. He got out the lube and started to finger the Latino man’s muscular ass. His dick throbbing at the sight of it begging to fuck it. After several minutes of fingering the guy’s ass he positioned his dick on the ring of the hole and slowly started to insert his dick. He kept trying to push but could not get more than the tip in. The guy was much too tight. He tried pushing harder, but then the Latino man interrupted him saying he did not think he could take it.

Doug screamed in his head; he desperately wanted that ass and was tempted to just keep going. But he relented and pulled back. The Latino man apologized and then said he had to go, quickly leaving Doug’s apartment and also leaving him with the biggest set of blue balls in existence. Doug was livid; he finally found a hot guy to hook up with, and he could not even take his dick. He went from being too small to being too big in one day, just his luck. His dick pulsed, the ache still present.

He logged on Grindr again, determined to find another guy. Maybe this guy was just too tight. He responded to several of the messages from hot guys enjoying his torso and would respond with his dick pic. He received rejection after rejection. Everyone was saying it was super-hot and sexy but that they did not think they could bottom for him. Many offered to suck him or jerk him off, but that did not appeal to him in his current state. After several hours of failed attempts, he decided to go to his personal gym to work off some steam.

He wanted to focus on his upper body today since he did legs yesterday. He started with the chest press, loading up the bar with two 45-pound weights and two 25-pound weights. Slightly higher than his previous max. He was able to knock out 15 reps with ease. He decided to be aggressive and added another 45-pound weight to each side. The first rep felt super challenging, and he almost re-racked it but felt his dick throb and decided to push through. He pushed the weight up with all his might, finally reaching the top and feeling a massive explosion of cum in his shorts. He started on the second rep, and it already felt easier; by the 12th rep he was having no problems.

He racked the weight and looked up in the mirror. His chest looked super pumped and was resembling one of those jacked bodybuilders he always jerked off over. He stood up and marveled at his body and huge hard cock. It was a shame there was no one here to enjoy it. He quickly pushed that thought away and decided that he could enjoy it himself. He started doing bicep curls, looking at himself in the mirror. Watching as his muscles swelled and got pumped was so erotic and caused him to cum several times in his shorts. He continued this process for several hours until he finally got tired. The puddle of cum seemed to have grown larger from yesterday as he cleaned up. He made himself a huge meal and then headed to bed. His cock finally satisfied from the lifting. He quickly drifted off.

He woke up the next morning with another throbbing erection. He removed the sheet and did a measurement noting that it had only grown about an inch reaching just above nine inches. It was also slightly thicker at about five inches around. He wondered if focusing on his lower body caused his dick to grow quicker. He then went to the bathroom to inspect the rest of his body. He gazed in the mirror, his eyes first looking at his big, meaty pecs, which were huge and had grown so large he now had pec cleavage and a deep valley in-between each pec. It was so fucking hot, he started massaging the huge pecs and came instantly. The huge ropey load fired from his cock all over the mirror. He wiped it off and continued to inspect his upper body. It was mesmerizing, like he was a real-life pumped bodybuilder. He lifted his biceps and began to lick the huge muscular mounds, firing another load all over the place. Fuckkk… he thought. His body was really turning him on as he became more and more like the morphed images he had always jerked off to.

His dick started to ache again lusting for some hot muscle ass. He cursed to himself; he needed to find something to fuck badly. He remembered the second injection. If he could find the right guy maybe he could transform him into “the ultimate bottom” the pamphlet had talked about. He thought they were exaggerating about normal guys not being able to take a “the power top” but seeing his growth over the last couple of days and his insane libido he understood why. He needed to find someone who was into muscle growth for this to work. The flaky guys from Grindr would not cut it, and he only had one shot he could not afford to waste.

His mind drifted back to his ex. Well, he would not even call him an ex; it had been more of a situationship that lasted for a couple of months. They originally met on a muscle growth site and had exchanged some hot messages. They eventually met and proceeded to start hooking up. His name was Chris, and he was a six’one athletic white guy with a decent-sized cock at seven”. The sex was excellent, with Chris being a total top and fucking Doug whenever he felt like it. After a dozen or so hookups, Chris had seemed to get bored and stop messaging Doug. This had really bummed him out since he was getting into the guy and felt like he was just being used. Oh well, a fuck is a fuck, I suppose. Chris lived pretty close, about a 10-minute walk, and had actually given Doug a spare key he never asked to be returned.

He knew Chris liked big, freaky muscles since they had traded many pics of their fantasy guys. The thought of turning him into a muscle power bottom also made his dick ache. All the times Chris had fucked him without care made him eager to do the same to him. This scenario was getting so hot in his head he started to jerk-off and quickly shot another load thinking of Chris as a hot muscle bottom riding his dick.

He started to come up with a plan on how he could inject Chris with the serum. He had some extra sleeping pills available that were super strong from when he was sick. If he could knock Chris out, he could probably inject him without issue. He also had a bunch of small cameras he had bought for a side project. He could install them around Chris’s place so he could monitor his progress. He figured if the blue serum worked anything like the red one, in four or five days Chris would be so hungry for a massive cock he could simply walk into his apartment and he would be begged to be fucked. The scenario made his dick ache with anticipation... He smiled, knowing he needed to do it.

He proceeded to get dressed; due to his recent growth most of his clothes no longer fit him, so he settled for some extra-large gym clothes. He walked over to Chris’s place and snuck up the stairwell. When he got to the apartment he put his ear to the door, listening for any movement. Chris usually hung out in his room when he was home. He did not hear anything, so he quietly entered.

As he came in, he could hear Chris humming from his master bathroom. There was a drink on the table freshly poured. Just his luck... He quickly ran over and dropped the pill in the drink. He then quietly walked to the second bathroom to hide. He knew Chris never used it. Several minutes later he heard the movement of Chris coming out to grab his drink and then heading back to his room. He figured he had to wait maybe 30 minutes, and then Chris would be out cold. His dick started to get hard again aching for release, but he pushed it down, not wanting to make any noise.

After 30 minutes he quietly left the bathroom and then slowly walked to Chris’s room. He could hear some light snoring and carefully entered the room. Chris was face down on his bed completely out of it. He walked over to Chris and pulled down his shorts, revealing his hot ass. He forgot how great of an ass it was, and his dick throbbed at the sight of it, desperately wanting to fuck it. He again calmed himself with all his self-control.

He took out the serum and proceeded to inject Chris with it. There was no reaction from him, so he took the opportunity to feel his ass a bit more. It was so fucking hot and he felt like cumming. He needed to get out of there quick, though, so he finished placing the cameras throughout the unit and snuck out. He raced home and sprinted to his unit his cock throbbing the whole way.

As he got into his unit, he burst in a massive orgasm all over his shorts. The experience had gotten him so horny, and he was deep in his fantasies. He cleaned up again and then made a huge breakfast. As he was eating, he started thinking about his dick: it was already huge at nine inches, but he could probably make it freaky like those obscene muscle morphed pictures. The pamphlet did say the blue serum allowed the injected to take “extremely large penises.” Fuckkkk, the thought of him walking into Chris’s place with a massive, freaky dick and fucking his brains out caused him to cum in his shorts again.

He cleaned up again and then finished his meal. He then went to his weight room; he figured if he focused on his lower body again he could potentially increase his dick growth like before. He started with squats again, upping the weight to five 45-pound plates. The first rep felt near impossible, but he gritted his teeth and kept pushing feeling the surge of energy and his cock throbbing. After 15 feverish seconds, he finally completed the rep, blowing a huge load in his shorts and feeling it drip down his leg. He looked up into the mirror and smiled looking at his pumped legs. He completed several more sets with a similar intensity before switching to various other leg exercises. After five hours of the intense leg workout, he finally stopped feeling completely spent and his dick satisfied. He laughed at the puddles of cum everywhere and had to get a mop and bucket to clean things up. He took a quick shower to relax his aching muscles and then headed to bed falling asleep quickly.

He woke up several hours later excited with anticipation. He threw the sheet off to reveal an even larger throbbing cock. He got his tape measure out and measured it at just over 12 inches long and seven inches wide. Upon seeing the number, he came all over himself. Holy fucking shit, he had a foot-long cock. He went to the bathroom and looked over his newly grown legs. His quads were huge now, causing him to waddle a bit when he walked and pushing his cock out making it look even bigger. The rest of his legs were just as developed as he ran his hands over them feeling the massive muscles and flexing them. The process was so erotic for him that he started to jerk his cock again exploding everywhere. He cleaned up and was going to put on some workout gear, but nothing would fit him now. He laughed at that and decided he could just work out naked since he made such a huge mess of his clothes anyway.

He opened up his phone so he could check in on Chris with his camera. Chris was walking around his apartment nude and was casually rubbing his ass. Eventually Chris went to his room and got out a small butt plug and inserted it. He appeared satisfied by it. Chris was already looking a bit more muscular as well; he had probably worked out yesterday. Doug’s dick throbbed and ached at the sight. He stroked his dick casually. Fuck... A couple more days and Chris would be the perfect power bottom. He needed the biggest dick possible to satisfy that hungry ass.

He made another huge breakfast and then headed to his home gym. As he walked in, he took a double take in the mirror, not recognizing the person. He was looking bigger than any bodybuilder. He did notice that his legs looked more developed than the rest of his body though. His dick ached and throbbed at the thought of growing bigger, but he also yearned for more muscle growth in the rest of his body.

He decided on trying to do more compound exercise instead of individual ones like the previous days. Maybe that could cause growth in his whole body. He loaded up the bar for a deadlift putting eight 45-pound plates on each side. He tried to lift it and couldn’t. He was going to take off some weight but gritted his teeth and forced himself to try again. He screamed as he made another attempt, and the weight slowly came off the ground. His dick spasmed and ached as he slowly lifted the weight up exerting all his strength and finally completing one rep after 30 seconds. Cum was leaking from his cock like a faucet. He ignored it and started on the next rep completing it much easier.

After 12 reps he finally dropped the weight and looked in the mirror. He already had a massive pump over his whole body and his cock was rock hard. He went through every compound lift he could think of pushing all his muscles to the max. After an eight-hour grueling session he finally felt spent. There were puddles of cum everywhere and he laughed as he had to fill several buckets to clean it up. He had a shower to rinse off than headed to bed.

He woke up with the next morning excited to see if his new strategy had worked. His cock was at full mast as he took the covers off, and he quickly took out his tape measure. It came in at over 16 inches long and 10 inches wide; his balls had also swelled to the size of large apples. His dick throbbed and ached in front of him, looking massive and freaky and oozing pre from its head. It was so large now he could easily suck it. He bent over, licking the head, then inserting the whole thing in his mouth and shooting a massive load down his throat. This was so hot; he looked like a freaky muscle morph from one of the pics on those sites. He got up and went to the bathroom. His whole body looked massive and pumped. His biceps were the size of a human head as he flexed them, and his chest was like two large pillows on his chest. He had a heavily cut 10-pack with deep, ridge-like valleys. And his legs were the size of two massive tree trunks. He came again just looking in the mirror. Chris had sent him a freaky photo once of a super-morphed guy and he looked about the same size as that photo.

He opened his phone to check in on Chris’s progress. He could see him in his room playing with a fairly large dildo; if he had to guess it was about eight inches. He was easily taking it and moaning on his bed. Doug smirked at the size of the dildo; that was him just a couple of days ago, and now he was almost double that size. He jerked himself watching Chris; he figured it would be two days max before Chris was craving a super large cock, and Doug would be there to fulfill that fantasy with the freakiest largest cock possible.

He decided to up the intensity of his work out even further by adding a superset of accessory exercise in-between his compound lifts. He wanted every muscle to bulge and pop like super jacked superhero. He started with deadlifts again, putting on 10 plates and screaming as he forced his body to complete the sets. He would normally have given his body several minutes to rest but immediately started to do some lateral raises to further pump up his muscles. The combination was truly deadly; every exercise left him in agony, but he kept pushing and watching in the mirror as every muscle group pumped up bigger and more defined. He pushed to almost 10 hours of working out before he stopped, feeling like he was about to collapse. He dragged himself to bed and passed out not even bothering to shower.

He woke up the next morning feeling a bit groggy, but still he opened his eyes and was greeted with the massive pole that was now his cock towering high in the air. Fuckm that was hot to look at, and he gave it a quick stroke and could feel some pre-cum dribble out. He removed the sheet and got out his measuring tape. The monster was now measuring 22 inches long and 14 inches wide. He waddled to the bathroom with his long hard cock smacking against his thighs. He was grotesquely ripped; the super-sets had done the work, and every small muscle was bulging and defined. He had put on considerably more mass as well and now did not fully fit in his bathroom mirror. He could not even see down at his body with his massive chest blocking his view. He relied on the mirror to admire his massive perfectly defined muscles. He was truly a muscle god in the flesh and shot a big load just looking at himself in the mirror.

He opened his phone to check on Chris. He looked like a massive bodybuilder. It seemed as though he had figured out that working out was the only thing that could relieve the horniness. He was lying in his bed with what looked like was a huge custom dildo—it had to be 14 or 15 inches. He slowly inserted it into himself wincing a bit but able to take the whole thing, and moaning as he shot a load all over himself. Fuck… it was so hot, and Doug shot all over himself watching it. He smirked again, looking at his cock, which was now over 22 inches and much thicker than the dildo. Chris would not be able to take this monster yet; it was just too big. The thought of being too big for someone really stroked his ego and made him feel horny. Chris would definitely be ready for him tomorrow, though, and his dick ached at the thought of finally being able to fuck.

He made his way to the gym determined to spend the last day growing even bigger. He set a goal for himself to figure out a way to maximize his growth and have his dick reach 30 inches. Even saying the words made his cock throb. When he and Chris had talked about cock growth their wildest fantasies never went past 24 inches. He was about to blow that out of the water and be even freakier than their wildest fantasies. He started by doing the compound exercises again followed by the supersets. It was super intense, but he knew he needed more to maximize his growth.

He had a bunch of weightlifting chains and belts. He decided to attach a bunch of weight to them and drape them around his shoulders and waist, effectively adding another 450 pounds to his body. The weights jostled and swayed as he completed his first deadlift. It was extremely hard to stabilize himself. His body quickly adjusted as he gritted his teeth and screamed pushing out the first rep. Than shooting a massive load all over the wall. He continued each exercise like this continuing to add more weight to his body. By the end of 12 hours he had almost 600 additional pounds on him. He collapsed from exhaustion, every muscle depleted and sore. He dragged himself to bed, satisfied he had done all he could and eager to see the results.

He woke up the next morning feeling energized and greeted by the hugest erection he had ever seen. The sheet had fallen off during the night, so his dick was just throbbing and leaking pre-cum standing straight in the air. He eagerly got his measuring tape out and rolled it against his cock. It went past 30 inches to 31 and measured slightly below 32 inches. It was also nearly 18 inches wide. Seeing those stats caused him to erupt with a volley of cum all over himself. His balls had also grown massive like two large melons. He was the biggest muscle freak possible, bigger than any of their fantasies. He smiled broadly, and knew today was the day Chris would get to enjoy it and become his ultimate bottom. That slut would only ever be satisfied by his freaky cock and insane body. He got up and waddled his way to the bathroom. His quads were so massive it was hard to walk, and the rubbing made him instantly hard. He chuckled as only a small portion of his massive frame could now be seen in the bathroom mirror. He took a quick shower, having to hose himself down and barely fitting in the shower area.

He was about to get ready to walk over to Chris’s place when he realized he had no clothes. Fuck. It was daylight outside; he could not walk over naked. He had been so obsessed with muscle growth he forgot to order anything to wear. He grabbed his king-size sheet and attempted to make a toga. He looked ridiculous, but it would be enough to hide his nudity. He was worried about getting the police called on him, so he decided to wait until it was dark and fewer people would be outside. His dick ached and throbbed not wanting to wait a second longer.

He opened his phone to check on Chris. He had just gotten back from the gym and was looking massive. Doug estimated Chris was about half his size, but it was still impressive and got him hard looking at the images. His ass was super thick and massive, though, and stuck out from the rest of his body. His cock flopped against his thighs and was probably about 11 inches. He smiled at this. His cock was almost three times as long and probably twice as thick. He desperately wanted to run over there and lift Chris up in the air and impale him on his cock. He continued to watch Chris and heard a knock on his door. Strange—who would be coming to visit him?

Chris opened the door to have a man walk in that was absolutely gigantic. He was seven feet tall, white, and looked way bigger than Doug even in his freaky enhanced state. The man started to talk in a deep voice asking Chris how long he had been enhanced for. Chris seemed confused by that, so the guy changed the subject and started to strip off his compression clothes revealing his massive muscles that seemed to further expand and bulge in size. Chris seemed mesmerized by them with his cock immediately getting hard. The man remarked, “You like my big muscles, little man? You a muscle whore? Mmmm, looks like the blue vial is doing its work on you.”

Chris seemed confused again by that last comment but was too focused on feeling the guy’s muscles. The man had a chiseled face and wavy hair and looked like he was in his mid-twenties. Doug was hard just looking at him and his perfect features.

He then proceeded to strip off his tight compression joggers, and his massive cock sprang free. It was a beast, easily 36 inches long and 24 inches wide. Much bigger than Doug’s monster. He proceeded to lift Chris up and slowly impale him on his huge cock. He moaned, “Yeah, you little slut, you have a tight ass; you’re going to make a good fuck toy.”

Doug couldn’t look away and started to feel cum shoot from his cock from watching the bigger man fuck Chris, who seemed to be in ecstasy. After about an hour of intense fucking and multiple loads shot into Chris, the man pulled out with a plop and put Chris back on the ground. Chris seemed desperate for more. The man responded, “Thanks for the fuck. I have a pretty big roster of horny muscle bottoms, but I’ll hit you up in a week for another session.” He then put his compression clothes back on and sauntered out the door, leaving Chris in a puddle of his own cum and whimpering for more.

Doug’s head started to spin. Chris would never be satisfied with him after fucking a muscle god like that. He had to get bigger and sexier somehow. He went back to the original site he had ordered the vials from and started to go through the site. He found the same compression cloths the guy had been wearing, under a section headed “Need to look a bit more presentable in public? These clothes will help to hide your freaky form.” He looked at the price tag: $5000 for a set of clothes? Holy shit, seems like this was how they really made their money. He went ahead and ordered them with express delivery.

He started to look through their other packages. One vial read, “Want to look younger? This vial will take 10 years off your age.” Another $5000? Fuck, he went ahead and ordered. There were several more options: one for chiseled features, one for wavy hair, one for perfect skin. He ordered them all.

He kept scrolling and found more to further enhance dick and muscle growth, and he ordered both. Another one said it would increase recovery speed and stamina, so he ordered it as well. $100,000 later, he had ordered every possible option all on express delivery. He received a note from the admin saying due to his large order they would hand-deliver everything today. He gave them his buzzer and asked if they could drop it directly at his door. They happily obliged.

His dick ached from all the excitement and frustration from not being able to fuck. He began to stroke his cock while he waited, shooting several loads all over the condo floor.

He heard a knock on the door an hour later and scrambled to cover up and answer. The package was discreetly set in front of his door, simple and unmarked. Guess these people know their clientele. He frantically opened the package, revealing the compression clothing and the 20 or so vials he had ordered. He opened each vial and began to inject them. His cock became painfully hard thinking about what they would do. After the injections were complete, he tried on the compression clothing. They fit like a glove and made him look presentable yet still sexy. He stripped them off and felt his muscle expand out and his cock spring to action. It was super-hot seeing it and he could see why Chris was so horned up by it. He could feel the new formulas working already and felt super energized.

He walked to his gym, determined to have the most intense session yet to maximize his growth. He needed to have the biggest cock possible to satisfy Chris’s ass after being fucked by that monster. He loaded up all the weight possible on the deadlift bar and draped another 1000 pounds over his body. He screamed in agony as he attempted the first rep, gritting his teeth and pushing with everything he had for what seemed like a minute. He kept screaming, and the bar slowly started to move up. Two minutes later he finally completed his first rep and fired his biggest load yet all over the mirror. He kept going completing every rep possible and pushing each set to 20 reps. After more than 15 hours and working every muscle possible, he finally collapsed and crawled himself to bed, barely able to move.

He woke up feeling groggy and slowly opened his eyes to see the most massive, freaky cock. It was bigger than any of the craziest morphs he had seen on the internet. He brought out his tape measure and was shocked by the measurements. It was 48 inches long and 36 inches wide. His balls had ballooned in size resembling watermelons. This fucking monster cock was easily a foot longer than the guy from yesterday and a foot wider. He started stroking it firing off huge volleys of cum. Fuckkk...he was bigger and freakier than the stud from yesterday. He would out-fuck that prick with his gigantic new cock. Once he fucked a bottom, they would not be satisfied by anyone but him and his freaky mega cock.

He came several more times to the fantasy before finally making his way to the living room to view himself in the bigger mirrors. There was no point in going to the bathroom in his enhanced state. He gazed into the mirror, not recognizing himself. Gone was the nerdy dork with glasses and strawlike hair. He now looked like a super sexy stud in his 20s. With perfect skin and chiseled facial features. Perfect wavy hair. Even his vision was flawless, with him no longer needing glasses. His body was that of a super-enhanced Greek god. Every muscle bulged like it was sculpted from marble. He was easily over eight feet tall and had to be pushing 600 pounds of pure muscle. His cock became rock hard by his reflection, and he started to suck on his massive cock as he worshiped his perfect body. After more than an hour of sucking and worshipping himself, he finally pulled himself off. He could do this all day, but his dick ached for ass. He quickly hosed himself off in the shower. Then he opened his phone to check on Chris.

Chris was in a deep workout session and had set up a weight room in his second room. He seemed to be trying to distract himself. He was probably aching for dick after yesterday’s sessions. Little did he know that an even bigger monster was coming for him.

Doug slipped on his compression clothing, surprised that they could actually hide his freaky form. He walked over to Chris’s place and took the stairs up to his apartment. He opened the door quietly and could hear Chris clanking the weight in the other room. He stripped off his compression clothing and then stroked his dick to its massive erect form. He waddled over to the room feeling his massive thighs rub against his balls and trying not to cum. He got to the doorway and began to stroke his cock as he watched Chris do squats and his amazing ass bulged. Chris was working out naked which turned Doug on even more. He made one comment, finally breaking the silence: “Looking for something to fill that hole, slut?”

Chris seemed startled initially, but as he turned around and saw Doug, he whimpered and came immediately at the sight of him. Doug sauntered over and made another comment: “Are you ready to know what a real cock feels like slut?”

Chris whimpered again and nodded his head as Doug lifted him up and positioned his massive cock against his hungry hole. He slowly started to push and felt Chris’s ass stretch to accommodate his massive cock like a tight glove. He pushed deeper amazed by how much of his freaky cock Chris could take. He pushed him all the way down to his balls, and Chris moaned in ecstasy and shot a load all over Doug’s chest. He responded by dumping a massive load in his ass which caused him to roll his eyes back in ecstasy. The fucking continued for hours, with Doug seeming to be insatiable. Near the 7th hour mark, they finally collapsed into Chris’s bed and fell asleep. Doug’s cock was still rammed up Chris’s ass as they drifted off.

Doug woke up several hours later feeling even more horny and ready to fuck ass all day. He felt like he could go on forever. The feeling of fucking an ass was euphoric to him, and he had to make up for years of lost time. He could hear Chris moving in the kitchen and started to get hard thinking of his hot ass. He walked out into the kitchen stroking his huge cock, and said to Chris, “Ready for round two slut?” Chris moaned again at the sight of his huge cock and perfect body. He finally stuttered… “Sorry, Doug… I need the day to recover; yesterday was super intense. I should be ready again tomorrow, I promise.”

Doug felt a flash of irritation; he painfully needed to fuck and this guy wanted to rest? What kind of ultimate bottom was that? Fuckkkkkk. He suppressed the thought and responded with, “No problem sexy. We can go again tomorrow. Let me give you some space to recover.” He then proceeded to put on his compression clothes and make his way back to his place. When he got back, his cock ached and throbbed eager for ass. He could not wait another day to fuck. What if it was two? His cock ached at the thought.

He remembered the comment the other enhanced guy made to Chris about having a big roster of bottoms. He thought it was weird at the time, but maybe this was a limitation of the formula. He brought up the site again and started to do some more reading. In his horniness he had ignored the various warnings, desperate for Chris’s ass. Apparently, some of the additional formulas he had taken can cause hyper-libido that the bottoms could not keep up with. It was recommended that only one enhancement to the formula be taken, with any more resulting in unknown results. Fuck… he had taken over 20 doses, foolishly just clicking on everything available.

He started reading through some of them again, and many of the enhancements resulted in increased libido and sex drive. He also read that it was recommended only to have sex every two to three days due to the massive size of the enhanced penis resulting in longer bottom recovery time. Doug cursed. There was no fucking way he could wait two to three days between fucks. He was so insanely horny. He kept looking through the site until he found a forum with various posts. One posts talked about the number of enhanced guys in this city. Looked like there were just under 100. The distribution of the formula was also interesting. Apparently about 80% of the guys took the blue formula. Most of the ones taking the top formula ended up pairing up with one guy, leaving only a handful of guys to service the rest of the horny bottoms.

He found another thread talking about how the bottoms would automatically adjust to the largest cock they were fucked by. Very enhanced tops therefore resulted in bottoms only being able to be satisfied by the top in the area with the biggest cock. He kept reading and found a forum for his area where people looking would post. Near the top was a post from the guy that had fucked Chris. His name was Mark. His post contained several photos of his massive cock and a cocky line reading, “New power top in the city with the biggest cock ever seen. Send me a message for the fucking of a lifetime no one else can achieve.”

Doug had to admit he looked so fucking sexy but also seemed like an arrogant dick. He smirked as he jerked his dick… He used to be the biggest cock in the city. Doug’s monster clearly had him beat. There were dozens of responses to his thread of horny bottoms lusting after him. He clicked on one bringing up the profile of this sexy Latino guy with the perfect ass. Doug got painfully hard looking at him. He sent him a direct message: “Looking to get filled by a real dick?” He then sent several shots of his new massive cock. The Latino guy responded almost immediately. “Holy fucking shit man that thing is massive, makes Mark’s look small. Where are you located? I can be over right away.”

Thirty minutes later, Doug heard a knock on his door. He answered it completely nude and fully erect. The man on the other side was gorgeous but upon seeing Doug started to cum in his pants. Doug grinned and lifted the Horny Latino up and positioned his massive cock against his hole than thrusted deep inside him. The Latino guy shot a load immediately with Doug quickly following filling his guts with his seed. They fucked for a good three to four hours before the hot Latino finally had to stop. Doug was surprised figuring he would last at least eight hours like Chris. They started chatting a bit and he found out the Mark was an even bigger dick than he imagined. Apparently, he would only fuck his bottoms for an hour max so they were left unfulfilled and desperate for more. The magic number seemed to be around three hours which left the bottom feeling completely satisfied for several days. Mark had also apparently super enhanced his dick pushing out the couple of other tops who had been in the city. Leaving him as the only option for most of the horny bottoms. The Latino guy was therefore overjoyed with their fuck and wanted to come back in three days for round two. They kissed before he left, the Latino man eager for the next encounter.

Doug however was still left painfully horny; it felt like he needed to fuck for 12 to 15 hours a day to be satisfied. Fuck…. What had he done? He was going to have non-stop blue balls. He went back to the forums and messaged another guy. It was a super sexy Korean man who had the perfect lips and gorgeous ass who raced over after his message. He got through three more guys that day for a total of five before he finally felt satisfied and ready to sleep. Doing the math in his head he would likely need a roster of 15 to 20 muscle bottoms to keep him satisfied. He figured Mark was probably being greedy and had upwards of 60 guys on his roster so he could fuck whenever he wanted. Surely, he would not miss 20 of them especially when they were being serviced much better by him. As he was about to go to bed he got a message from Chris saying he was still recovering and likely needed another day. Doug figured he probably needed two days based on how long they fucked compared to the other muscle bottoms he had fucked today. Hey drifted off finally spent for the night.

He awoke to a painful erection towering in the air and several alerts on his phone. The Latino guy had sent him a link to the forums to a new thread that had been created by Mark. He started to read the thread. Mark wrote, “Apparently there is a new power top trying to steal bottoms. I have seen his pics, and he looks like a nerd who is out of his league. Looks like the standard for a power top needs to be updated.” He then linked several photos of his newly enhanced massive cock. It looked like it was 56 inches long and 42 inches wide. A massive jump from his previous size and big enough to dwarf Doug’s cock. Fuck, this guy must be super threatened by him to get that big. He must have taken several enhancements that would drive his libido even higher than Doug’s. With Mark having such a high libido there was no way Doug would be able to satisfy any bottoms. In a couple of days, Mark would have fucked all the enhanced power bottoms available completely locking Doug out. Fuckk… he thought to himself he had to get bigger; it was his only option to compete.

He went on the site and ordered three more vials on express delivery for increased muscle and dick growth, grimacing at the side effect of increased libido. He would just have to manage that. He figured he needed at minimum 12 more inches of cock growth to beat out Mark, likely more to lock him out completely. The vials quickly arrived at his door and were placed under it. He opened the vials and had a thought. He had previously injected them into his leg; maybe if he injected them into his balls the growth might be more potent. He proceeded to inject all three into his balls. He could feel the formula work instantly and watched his balls inflate a little. He then waddled his way to his weight room. After two days of fucking, he was excited for an intense workout. He went through a similar rigorous exercise routine but added on some additional bodyweight exercises that proved to be very challenging considering his massive size. Every exercise resulted in him shooting huge loads all over the workout room. By the end of the 15-hour session there was a lake of cum covering the ground. He was completely exhausted and dragged himself to bed and drifted off to sleep.

He awoke to a dribble of precum landing on his face. He opened his eyes to see his gargantuan cock pulsing over his head. He moaned as he started to measure it. The tape measure read 65 inches long and nearly 52 inches wide. Fuckkk, he had only needed 12 inches and got 17… injecting the formula into his balls must have upped the growth. He also instantly felt the increased libido with his dick throbbing constantly to the point he could not ignore it. He snickered… Mark thought he had me beat, but look at this new monster. I’ll probably need a roster of 30 guys to keep me satisfied. Fuck... I might just have to fuck them all to lock out that asshole.

He started to immediately message guys who had responded to Mark’s thread to come over, showing them pics of his newly enhanced dick. It looked like Mark had been rushing through everyone, only fucking guys for 30 minutes, which allowed him to imprint his dick size but left them open for more rather than recovering. He lined up seven guys today and planned to fuck all day.

The day became a blur of sex and ass as he fucked non-stop. Even after fucking for 20 hours straight, he still was not satisfied, and his dick throbbed begging for more. He lined up three more and fucked deep into the night. After nearly 10 guys and 30 hours of fucking he drifted off.

He had only slept for a couple of hours before waking up fully energized and his cock throbbing for more. Fuck, this new libido and stamina was intense. He immediately started messaging more guys. He was three guys into his latest fuck-a-thon when the guy mentioned something interesting. Apparently, Mark was not available today. Doug immediately became paranoid. Was he doing another enhancement? Had word already gotten to him of Doug’s massive new size. He supposed all he could do was wait and fuck in the meantime. He completed his second day of fucking racking up 11 guys before finally passing out.

He awoke several hours later to several bottoms messaging him links to Mark’s thread. He opened it and started to read.

Hey Doug, I know that’s your name and where you live you little bitch. You thought you could outgrow me? Fat chance you nerd. Feast your eyes on the final standard for a power top.

He had posted several pics. He looked like the fucking Hulk, with a massive 80-inch throbbing cock that was 65 inches wide. He was easily 10 feet tall and rippling with insane-looking muscles.

Doug felt a pit in his stomach; there was no way he could do another round of growth. His libido was already way too intense. He could not imagine how raging Mark’s was. He remembered reading something in the pamphlet, though, and walked to his kitchen to pick it up. Apparently, the max size a bottom could take was 70 inches, with larger than that not being possible with the current formula. There was a note about an enhanced bottom serum being developed, but it was still in testing.

Doug smiled. It looked like Mark had not read the pamphlet either and had just outgrown his ability to fuck his roster. He got a message from the Latino guy saying that he heard that Mark had messaged several guys to fuck but was unable to get inside them. It seemed like he was correct. Doug chuckled and started lining up his fuck order for the day. He was now the only power top available and would make good use of it.

He later heard that Mark had left the city to join a trial for the new serum. Apparently, he was the largest subject ever and so was a perfect specimen for whatever they had in store for him.
