Ass-centricity - Part 3
🕑 Added 2017-10-19 05:16:08 +0000 UTC“Guys, please, this really isn’t necessary!” Nick pleaded, but his requests fell on deaf ears. Neither Chaz nor his two friends seemed to be listening as Chaz once again produced a needle seemingly from nowhere.
“Alright boys, hold this little guinea pig down for me,” he said, and the pair grabbed Nick and hauled him to be face down on the same table he’d been on weeks ago. He could feel Chaz pull the waist of his jeans over his already bulbous buns, and then a slight pinch in each cheek. Then a rush of warmth came over him as he felt his glutes begin to spasm and cramp, and then the familiar feeling of tightness overcame him.
“Oh god, not again,” Nick thought as he heard the first rip of his brand new jeans. His bowling ball-sized buttcheeks seemed to inflate with muscle and fat until they were the size of basketballs, blowing through the denim that had enclosed them explosively. They jiggled enticingly in the cool air of the room, which was becoming hotter in the presence of the four men.
“Woah,” one of Chaz’ friends commented, but the serum wasn’t done yet. Rips appeared up and down Nick’s pants as his legs expanded, looking like overstuffed sausages as the limbs grew and thickened. Then they too were revealed as the denim finally gave way, their violent eruption from their former prisons causing the enormous hams to wobble for a few moments along with his massive buns. Nick’s calves weren’t far behind, blowing up to become larger than any of the men present. Even his feet became thick and chubby, the soles of his shoes tearing open as the growing flesh ripped them apart.
“Now that’s what I’m talkin’ about,” Nick heard Chaz say before a heavy hand slapped his ass. The feeling was completely muted due to the thick layer that had grown over his glutes, but the sensation of motion as his flesh rippled at the impact felt oddly amplified.
“I’ve never seen an ass that big,” the one holding down Nick’s left shoulder said, and through the corner of his eye he could see a bulge appearing in the man’s jeans. He couldn’t believe this was happening again, and he was horrified at the thought of what these men might yet do, and yet he couldn’t deny a part of him felt incredibly aroused at the fact it was his ass that was arousing these dudes.
“Oh, he’s not done yet. I gave him a double dose this time. Boy’s gonna get huuuuge,” Chaz said, and Nick’s heart stopped. Once again a wave of heat came over him, although he couldn’t tell if it was the intense embarrassment or the serum. This time the constrictive feeling wasn’t on his lower body, as it had already long since blown through the clothing that had encased it, but his upper body. He could feel his shirt tighten around his arms, neck, and chest as his expanding torso outgrew their cotton prison, although not nearly as much as his lower body had.
Then Nick felt the familiar cramp in his glutes and realized his ass was hardly finished. Even though there was no longer any sense of restriction he could just feel his rear grow, as though every new inch that appeared gained its own set of neurons telling him how much more space his ass now took up, how much more air caressed the smooth and quivering skin.
It was the same for his legs, thighs, and calves, the two halves of Nick’s sneakers now completely separated by his expanded foot and ankles, falling in tatters to the floor and leaving him naked from the waist down. Nick couldn’t imagine how large his lower half had gotten, but from the constant sense of motion and the way it was magnified by even the slightest twitch, he knew he had to be utterly huge.
“Jesus fuck, what a fat ass,” the guy to Nick’s right said. “Look, Chaz, I thought this was going to be something that builds muscle, not turns you into a fuckin’ whale.”
“Oh, he’s got muscle. Stand him up, I’ll show you,” Chaz replied, and Nick felt the hands pressing him down into the table instead haul him back to his feet. Or try to - he’d gotten significantly heavier, and even needed Chaz’s help to get him standing.
Once up Nick looked down and moaned. He was huge, bigger than he ever thought a simple needle could make him. His soft belly now sagged over his front while two perky tits perched atop his chest. If his upper body could have been described as pudgy before, but now it looked undeniably fat.
But it was his bottom half that was unreal. It looked like it belonged on a champion sumo wrestler. His hips bulged to the sides as they sloped into enormous legs that were as wide around as his chest. Reaching behind he could feel the enormous spheres of fat that had become his butt, the size of two beach balls squished together for lack of room. He couldn’t see what was below his titanic thighs, but he could already tell they were larger than anything he thought possible on a human being.
His captors backed off and left him standing at the end of the table, and Nick tried to take a step. He quickly found that even the wide gait he previously had wouldn’t do, and now he had to swing each leg around the other just to achieve a slight forward waddle. All the while every inch of him quivered and shook with the effort. He waddled to one end of the room and then turned to face his tormentors.
“Ok, boy’s gotta have some muscle to even move at that size,” Righty said, as Nick had silently named him. “But I still don’t have any desire to get an ass bigger than my girlfriend. Plus you musta put Viagra in that shit or something ‘cause fat boy’s got a boner.”
Nick’s face immediately flushed red as he realized he was standing in front of three men with a raging hardon. Somehow he’d hoped that his enormous thighs would hide his manhood, but even with over a hundred new pounds his little red helmet poked through for everyone to see.
Worse, Nick couldn’t tell why he was so hard. Maybe Righty was right - maybe there was Viagra in the serum? But a voice in the back of his head said that wasn’t the case, and there was something about this whole situation that was turning him on.
But not everyone was as aroused as Nick. “I’m out. Enjoy your fat-ass fucktoy,” Righty said before brushing past his buddy to head back upstairs, leaving Nick alone with Chaz and Lefty, who’s obvious bulge had not died down since Nick had stood.
“Fuck Dave,” Chaz said, finally naming Righty after he’d already left. “More for us, right?” He said to Lefty, who smiled and nodded. Then the two advanced on Nick, grabbed him, and shoved him stumbling back toward the table.
“I know you’re the ass-man, Chaz, but this thing is calling to me like I’ve never felt before,” Lefty said, and Nick suddenly understood exactly what would happen next. “You get sloppy seconds.”
Chaz chuckled and nodded, the two of them again hauling Nick onto the table (with considerable effort) and this time laying him on his back. Then, before Nick could even protest, Lefty dropped his jeans and forced Nick’s legs apart, revealing the deep trench leading to his hole.
“You’re lucky Dan here has a pretty big tool, otherwise he might not even get all the way inside an ass as big as yours,” Chaz whispered by Nick’s ear as he felt Dan’s hands spread his cheeks as wide as he could. He felt fingers probing beneath him as Dan searched for his hole, digging into the soft flesh of his rear more than he thought necessary until he finally found it. Then he stepped forward, his bare hips pressing as far into the fat of his ass as possible, and lined himself up. He indeed felt like he was hung like a mule.
“Woah, hold on, I don’t- mmmf!” Nick tried to protest but suddenly had his face covered by Chad’s hairy taint. The man had disrobed while Dan was fingering him and silenced him in a way that filled his vision with Chaz’s balls and ass - balls that seemed especially large, and an ass that seemed especially hairy.
It was also unexpectedly soft, smothering Nick almost to the point of suffocation. “Good one. I hate talkers,” he heard Dan say, and then pushed his hips forward and slid inside.
Nick expected it to hurt, and it did at first, but not nearly as much as he’d thought it would. After a few moments, the pain went away and Nick felt a wonderful fullness that he’d never felt before - a fullness that got his already hard cock leaking into his fat-covered groin.
“I’ve never had a hole take me so easily. This boy’s like fucking plush velvet,” Dan said, before sliding himself out and then sliding all the way back in, pressing into Nick’s enormous thighs as far as he could go. He managed to get himself an inch further in, which managed to reach Nick’s prostate for the first time.
He moaned around the taint covering his face, and Chaz knew Dan had hit the spot. “Do that again,” he commanded, before leaning over Nick’s face from his former crouching position. “And you - eat me out,” he commanded again and then Chaz brought his hairy hole over Nick’s mouth.
Nick had never thought about eating out a man before - sure, he’d done it to a woman, but this felt entirely different. It was all-encompassing, smelled like sweaty taint, and was much, much hairier. But then Dan once again pressed forward and caused Nick to moan out loud, and Chaz lowered his hole so it completely covered Nick’s open mouth and then ground on top of him.
It was at that point that Nick simply disappeared. His world became the dull slap of the man plundering his hole and the taste of sweat as he ate out Chaz’s. He was dimly aware of Chaz’s more baritone moan as he darted his tongue in and out of the hole before him, slobbering the hairy taint with saliva whenever he pulled up to allow Nick to breathe. Then he’d plunge back down and Nick would again go wild on the furry flesh before him, all the while his prostate sent incredible pleasure throughout his fattened form.
“Oh shit,” he heard and then felt Dan slam into him with enough force to send his entire body rippling from the effort. Then he came, and Nick could feel the liquid filling his insides. It felt like a lot.
Dan pulled out with a lewd slurping noise and through the corner of his eye Nick saw what had just been inside him. It looked to be the size of a 24oz beer can, and he had no idea how that had fit. Then Chaz got up from his crouch and made his way to where Dan had been, shoving his own cock as deep inside Nick as he could.
Nick could barely feel it, and the incredible pleasure that Dan had provided wasn’t nearly as present.
“Like a hot dog down a hallway, huh?” Dan said snidely from the side as Chaz humped away.
Between breaths he heard Chaz reply, “It’s enough for me.” Then Nick felt him grab his cock and begin to pump in time with his thrusts, giving Nick a more familiar and insistant pleasure. Looking down over the crest of his belly, he could see his cock seemed much diminished, the fat of his groin having swallowed several inches. Chaz had to push into the flesh to stimulate his entire length, but he seemed more than willing to do so.
In minutes Nick was panting and ready to blow. Chaz’s thrusts had picked up pace, and it felt like he was jackhammering into his well-padded rear. As he felt his peak rising he called out, and then came, his seed fountaining over him to splatter all over his belly.
The sight was enough to get Chaz off as well, and he added his more meager load to the one already left by Dan. Then he slapped his thigh and said, “Great work, fat boy,” before both he and Dan put on their pants and left him there in a puddle of semen.
