Pills

by BigStories

A couple orders some pills to help stack on size, but only one of them understands what's to come.

“What if they don’t work?” Mitch asked.

Jake laughed. “Then they don’t work.” He popped two pills in his mouth and downed them with his protein shake.

“What if only yours work?”

“Why would two pills from a bottle work, while two others don’t?” Jake smiled. “If you don’t want to take them, you don’t have to. But I’m all in at this point.”

Mitch stared at the two pills in his hand for a moment before taking them. “Had to do it before I second-guessed it again.” He smiled. “Now what?”

“We wait, I guess?” Jake shrugged. “I can think of a way to pass the time.” He grinned as he pulled his shirt over his head and kicked his shorts off, revealing his smooth, muscular frame. At 5’10” and 195 pounds, Jake had an impressive build, but one he wasn’t satisfied with. However, he had always been too afraid to try any steroids, so his growth had stalled out in recent years.

Mitch headed to the bedroom and disrobed, revealing a similar build. Thankfully, the two avoided “boyfriend twins” jokes on account of their different complexion and hair, but they were in similar shape and both relished the smooth pornstar look.

As Jake crossed the threshold of the bedroom, Mitch grabbed Jake’s wrist, pulling him forward and into an aggressive kiss. Mitch’s tongue darted into Jake’s mouth, trying to worm its way into Jake’s throat. Jake moaned into the kiss, his tongue battling Mitch’s. Mitch broke the kiss and the two panted. Caught up in the moment, neither noticed the pills starting to take effect, causing them both to feel hot and begin sweating already.

Mitch leaned down and took Jake’s nipple in his mouth. He flicked his tongue over it, gently nibbling on it. Over and over, he alternated suckling and lightly biting his nipple and pec meat. Jake threw his head back, his cock hardening and beginning to drip precum. Mitch grabbed it and started pumping, his rough hands smearing Jake’s precum down his cock. As he did so, Mitch’s cock hardened, as well.

Mitch spun Jake around and shoved him back on the bed. He took Jake’s 9-inch cock in his mouth, down to the root in one go. Again, Jake threw his head back, moaning. He put a hand on the back of Mitch’s head and started gently thrusting. Mitch expertly deepthroated his cock, swirling his tongue around the head, licking up the precum. He pulled off and pushed Jake fully down on the bed, exposing his hole, which Mitch began to tongue furiously.

“You’re extra feisty,” Jake said through his moans.

“Well, if these pills work, we’re in for a real good time, right?” Mitch stood after attacking Jake’s ass with his tongue, saliva dripping from the semi-open hole. “I guess I’m just excited.” He gently prodded his 8-inch cock into Jake’s hole, eliciting another moan from Jake.

Jake reached up and yanked on Mitch’s nipples. Mitch gasped and leaned down, kissing Jake again as he thrust in and out of Jake’s loosening hole. Jake continued to pull on Mitch’s nipples.

Mitch broke the kiss. “If you don’t stop that, I’m gonna shoot already.”

“Do it,” Jake said, pulling on Mitch’s nipples again. “Give me your load.” He pulled again, hard.

Mitch practically screamed as he started shooting into Jake. He collapsed on top of Jake, panting hard. Jake kissed the top of Mitch’s head and let Mitch lie there momentarily. When Mitch caught his breath, Jake grabbed Mitch around his waist and pulled him up. His cock popped out of Jake’s ass, cum dripping from Jake’s open hole. Mitch let himself be guided to Jake’s cock where he sat down, impaling himself in one smooth motion.

“Fuck,” Jake said. “Your ass always feels so good.”

Mitch smiled. “I keep it nice and loose for you,” he said, as he started riding it. “I know how much you love it.”

“I’m not going to last long,” Jake said.

“Good, I don’t want to have to wait for your load.” Mitch sat down fully on Jake’s cock and ground his hips into Jake.

“Wait..” Jake said, starting to feel dizzy. “Something feels off…” Mitch didn’t seem to hear him and continued to bounce on Jake’s dick, his own cock hardening again. “Mitch…” Jake pawed at Mitch, who only grabbed one of Jake’s hands and guided it to his dick. Despite how dizzy he felt, Jake started jerking Mitch off.

“Oh fuck!” Mitch shouted, feeling his ass stretching wider. “Is that the pills?”

Mitch felt Jake’s cock pressing deeper and deeper inside him, felt the walls of his ass getting stretched wider and wider. He looked down at Jake and watched as his muscles grew. The hand wrapped around his cock grew larger, the forearms attached to it thickened noticeably. Jake’s biceps, a respectable 15 inches to start, were growing closer to 19 inches. His chest inflated like a balloon. His neck widened. Mitch looked down and watched his own dick growing: It had to be over a foot long now and over 6 inches thick. He sat back on Jake’s cock and felt it grow inside him, feeling like it was pressing directly into his guts.

Jake, coming out of his daze, felt more than watched as Mitch experienced similar changes. Jake felt the additional weight Mitch put on pressing down into his lap. He felt Mitch’s already impressive quads thicken past 22 inches. With every pump, he felt Mitch’s cock lengthen in his grip. Without warning, watching Mitch stack on muscle while riding him, feeling Mitch’s hole spasm around his own thickening cock, Jake started cumming inside Mitch.

The two watched in awe as Mitch’s flat stomach distended. As more and more cum fired into his guts, Mitch rubbed his fattening belly, enjoying the feeling of being stuffed to the brim with cum.

“It’s so warm,” Mitch said. He started riding Jake again.

“Look at you,” Jake said, starting to thrust into Mitch. “You’re already pumped full of my jizz and you want more, don’t you?” He watched as Mitch’s stomach rippled every time he landed back on Jake’s legs. “I can see my cum sloshing around in your belly and you want another load?”

Mitch rode him harder. “Yeah,” he slammed down and ground his hips into Jake again. Jake pumped his hand around Mitch’s cock faster. “You’re gonna give me every drop. And I’m gonna paint those juicy tits white.” Mitch started cumming and ground down on Jake’s dick. Jake opened his mouth to catch as much cum as he could, but most of it ended up coating his new, thick muscles and covering his face.

“You taste so good,” Jake said, licking his fingers. He scooped some of Mitch’s cum off of his chest and held it up to Mitch. Mitch obediently sucked Jake’s fingers. As he did so, Mitch reached down and yanked on one of Jake’s nipples, causing the man to start cumming again. Mitch’s stomach lurched, expanding further, making his belly distend further. Jake once again felt Mitch’s weight increase on his lap, but this time due to the cum he was pumping into Mitch. Mitch threw his head back, moaning loudly, as he felt himself grow another ten pounds heavier, this time from all the cum sloshing around inside him. He rubbed his enormous gut and licked his lips, continuing to enjoy the feeling of being stuffed by Jake’s massive cock and huge load.

“Fuck,” Jake said. “That was… That was incredible.”

“Who said we’re done?” Mitch asked with a smile. “Someone didn’t read the full packet that came with those pills…”

Jake panted hard. “What? I’m totally spent. And look at you! What are we going to do with you, looking like that?”

Mitch laughed. “You really never read the package on anything, do you?” He shot Jake a sly grin. “Well, you’re the one who ordered them, so I’m gonna make sure you get your money’s worth.”

As if the pills were waiting for Mitch to make his point, as he finished speaking, his stomach rumbled. In a flash, his bulbous gut flattened into rippling abs. Each ab muscle looked like stone. The bed creaked as Mitch stacked on 20 more pounds of muscle. Jake’s legs ached as Mitch’s weight sank into them. Mitch’s legs thickened further, past 25 inches. His arms blew up to 23 inches; his pecs looked more like a pair of fake tits now. He pressed them together and squeezed, relishing the feeling of his own muscle tits plumping up in his hands. And his cock. It lengthened further, past 14 inches, and thickened up, well over 8 inches around. He slammed it down on Jake’s abs, smearing precum and cum over them. Jake felt the impact and winced as the cock hit him with a loud smack.

Mitch grinned. “I told you that we weren’t done.” He slowly pulled himself off Jake’s cock, squeezing his ass shut to keep the last bit of cum from leaking out.

Jake marveled at Mitch. “What the fuck?” He started to get hard again, looking at the monstrous form of Mitch.

Mitch grabbed the base of his cock and squeezed; a glob of precum belched out of the slit at the tip and fell onto Jake’s stomach.

“I told you you’re going to get your money’s worth,” Mitch said with a smile. He stepped off the foot of the bed and pulled Jake’s legs toward him. Jake’s legs spread out on either side of Mitch, and his ass pointed directly at Mitch’s crotch.

“Mitch, you’ve got to be kidding!” Jake tried to pull away, but Mitch’s grip on his legs was like being manacled to the bed. “You’ll split me in half with that thing. I’ve never taken anything even close to that size before.”

Mitch grinned. “First time for everything.”

Mitch released one of Jake’s legs and used his free hand to aim his cock at Jake’s hole. Even though Mitch had fucked him earlier, Jake’s ass was barely open. Mitch lined the massive head of his cock up with Jake’s hole and started pressing. Jake gasped.

“Mitch, no!” Jake said, trying in vain to scramble away from Mitch’s iron grasp. The pressure against his hole was immense.

Mitch pressed on, ignoring Jake’s protests. He applied more pressure and felt Jake’s hole start to give way to his cock. “I wouldn’t clench so hard,” Mitch said. “You know it’s always easier if you relax.”

“Relax?!” Jake shouted. “You’re basically trying to shove your forearm in me without any preparation and despite me saying no! That’s—”

As Jake’s protests reached a peak, his resistance faltered for a moment, and Mitch shoved himself forward. The head of his cock popped into Jake’s ass.

Jake screamed. He felt the walls of his ass split, making way for Mitch’s unyielding advance. His hole spasmed around Mitch’s cock, desperate to close, then recoiling from the monster inside. Mitch held firm, not moving forward, but not pushing any further inside Jake. Jake panted heavily. His ass ached, but surprisingly, it was much easier than he expected. In fact, it didn’t feel much worse than taking Mitch at his normal size, after not bottoming for a while. He blinked up at Mitch.

Mitch laughed. “That was fun. You big baby. I admit, you had me worried for a second when you screamed.”

“What the fuck, Mitch?”

“For the last time, I read the fucking packaging.” He pushed his hips forward, sliding more of his cock, slick with cum from their earlier fuck, into Jake. Jake groaned loudly. “I knew it wasn’t going to hurt.”

“You’re still an asshole for that,” Jake started to say, but Mitch pressed onward until his hips pressed against Jake’s smooth ass. Jake’s stopped talking to groan again. “Fuuuuck,” he said. “That feels so fucking good, holy shit.” His head was spinning from the sensation in his ass and belly. “It feels like you are up in my stomach.”

Mitch pressed forward, digging into Jake. “I probably am. Did you see how big this thing was before it went in you?” He smirked and pulled out slowly.

Jake moaned. His body quivered as Mitch pulled out, aching to have that huge cock stay put inside him. His hole clenched around Mitch, trying to keep Mitch from pulling out.

“Naughty,” Mitch said. “You better loosen back up for me.” He pushed forward again, harder this time. Jake nodded and tried to relax. “Atta boy,” Mitch smiled.

“I just don’t want you to take it out.” Jake said through his moans.

“Damn,” Mitch said, starting to pump in and out of Mitch. “You’re sounding like a real cock slut right now.”

“I am,” Jake said. He was so lost in the pleasure in his ass, he had forgotten all about Mitch’s body. As he looked up at Mitch’s new, towering form, he wasn’t sure how he could have forgotten. “I’m a slut for that huge muscle cock.”

“Yeah?” Mitch asked, slamming his cock in, hard.

“Fuck!” Jake shouted. “Yeah. You’re turning my hole into a pussy for your muscles.”

Mitch felt his cock jump as Jake said that. Jake shivered as he felt Mitch’s cock flex inside him. “Fuck, that’s hot. You got a loose, sloppy muscle pussy for me?”

“Yeah, I do. Don’t take that fat dick out, please.”

Jake reached up for Mitch, who leaned down and started kissing Jake hard. Even Mitch’s tongue had grown. Jake gagged slightly as he felt Mitch’s tongue invade his mouth. He tried to fight back with his own tongue, but Mitch’s filled his mouth and pushed everything in its way aside, just as his cock was doing to Jake’s ass. Jake moaned into Mitch’s mouth as Mitch started really slamming his hips into Jake over and over. Jake felt dizzy from pleasure and from a lack of oxygen as Mitch’s tongue filled his throat.

Overcome with pleasure, Jake’s cock started shooting between the men as it rubbed against Mitch’s thick abs. His hole pulsed around Mitch’s cock, who moaned. With one hand, Jake reached around to Mitch’s back, feeling the thick, wide muscles. With his other, he reached under Mitch and grabbed one of his nipples. He yanked hard. Mitch moaned loudly into Jake’s mouth. The combined stimulation of Jake’s ass contracting around his dick and Jake pulling on his tit pushed Mitch over the edge.

Mitch slammed his cock deep into Jake. His dick swelled and unloaded shot after shot of viscous cum into Jake’s guts. Jake moaned around Mitch’s tongue, and he felt himself get stuffed full of cum. Mitch broke the kiss and pushed off Jake. He put both of his hands on Jake’s pecs and held him down, watching as his flat stomach rounded into a beer belly, full of his thick cum. He kept his hips glued to Jake as his dick throbbed over and over, dumping more and more cum into Jake.

When he was finally done, Mitch pulled his dick out slowly, leaving Jake’s ass wide open, puffy, and oozing. Mitch collapsed on the bed next to Jake, rubbing Jake’s swollen stomach.

“What are we going to do now?” Jake asked, as he waited for the surge of muscle to hit him. “We’re not going to fit in any of our clothes, and we can’t suddenly show up to work 50 pounds heavier.”

Mitch smiled. “I ordered the ones to reverse it because I. Read. The. Packaging.” He laughed and pressed down on Jake’s stomach, forcing some of the cum to seep out of Jake’s ass.

“Hey!” Jake said. “I need that to grow.”
