First it was the huge display of manly masturbation he put on at the lab. He reflected on how he felt during that time... it was as if some force had come over him and taken over his mind, making him unable and unwilling to do anything other than furiously beat his dick off in a sexual frenzy. And it was the same way with Matt, too, except that something else had happened to make Matt full of lust and desire. It was like Matt saw him sitting there, naked and erect, and was so overcome with sexual desire that he couldn't resist Blake. But ordinarily, Blake thought he would have rejected Matt's advances - they were roommates, and friends, and didn't want things to be weird between the two of them. But when Matt came over to Blake, that force again took over. It was weird; Blake thought hyper-testosterone would make him aggressive and want to fuck Matt, not the other way around. But in a way, he DID feel hyper-aggressive; it was just that his aggression was turned towards being fucked. All of the thoughts made Blake's cock twitch and tighten during his walk to the lab, and he struggled to hide his boner as he made his way across the quad. "Yikes, this is so ridiculous and embarrassing," he thought, but was turned on at the same time by the prospect of doing more kinky sexual experiments with Sampson. He arrived at the lab and was directed to Sampson's office. Sampson further elaborated on his theory about Blake's condition: "You see... the average adult male's testicles produce testosterone at a base line level, all the time. During times of arousal and sex - or masturbation, they start producing more testosterone, to a level about 10x the base rate. However, during your test, we measured a base testosterone of 5x higher than that... if you've done the math, your base production is 50x that of the average man. We weren't able to measure production while you were masturbating, but..." his voice trailed off. "But it was probably insanely off the charts," Blake replied. "Yes. Your body is producing testosterone at a tremendous rate. And judging by your reply to my e-mail... it has an interesting effect on other men as well. We are extremely interested in studying this and I'm sure you are, too. If that's the case, we should set up a schedule for more experiments." Blake agreed. "This is all sorta overwhelming... but I have to admit, it's really hot, and I can't imagine the regret I'll feel later if I don't take this opportunity." The two men talked over a schedule and plan. "We'll be doing more tests to measure your testosterone output and how it affects your body," Sampson reasoned. "We can start today, with a test not unlike the first one we did. Only we'll be using more intense stimulation." Blake agreed and was eager to get started, so Sampson escorted him out of his office and downstairs to the examination room. "We've made some upgrades in anticipation of finding subjects of interest," Sampson told Blake. "This time, you won't need to wear any leads; we've got state of the art biosensors in the panels of the walls now, which should give us even more data and interfere a lot less." Blake entered the pure white room and sat on the hard plastic bench in the middle of it, as Sampson retreated upstairs to the control room. His voice filled the room via intercom. "Alright, Blake, we're ready to get started. Go ahead and disrobe, completely." Blake got naked, throwing his clothes into a corner of the room. Several thousand white lights twinkled on the walls around him: the biosensors flared to life. "Hold still," Sampson ordered, "we're doing some base calibrations with the sensors, now." The sensors blinked for a while, and about a minute later, faded from the wall. "Alright, we're ready to begin in earnest, now. A few things to note: for this test, we won't be able to give you privacy, I'm afraid. We'll be recording what goes on and saving it on a server in the lab, so we can review it. The server is internal and not connected to any external networks, so it'll be totally secure and private, only accessible by our research group. We'll also be showing you some porn on the screen as before... any preferences?" "Sure," Blake laughed. "How about some muscular jocks? I've got kind of a sports fetish lately..." "Coming up," Sampson said. Four videos flicked on to the wall, each covering up a quarter of its surface: first were two men sitting in jockstraps in a locker room, next came three guys playing football shirtless, third came two guys nearly naked in a weight room, and finally, a group of guys participating in a wrestling tournament. Blake recognized a few of the videos (he was a horny college kid and average porn watcher, after all), and became a little turned on already. "We've also got something to stimulate you a little more than just the videos..." Sampson said. A panel in the rear wall of the room opened up, and a machine moved out from the wall and towards the back of the bench. Attached to the machine was a large dildo mounted on a motorized rod. A bottle of lube sat next to the machine. "Is... is that ok?" Sampson asked. "Fuck yeah," Blake commented, staring down the sex toy with lust. The experiments really were kinky. He couldn't wait, so he grabbed the lube and squeezed some onto the toy, coating it in a thick layer, and fingered himself to prepare for the huge dong. He sat hands and knees on the bench, staring straight ahead at the front porn wall, and spread his ass cheeks apart as the dildo moved into position. The thick 7-incher pressed up against Blake's ass, slowly inching forward, uncaringly pushing into Blake's hole. "Fuck!" Blake screamed. The large dong moved further and further into Blake, causing him to wriggle and writhe in a mix of pleasure and pain. After it was fully inserted, the toy began to vibrate and pulse, and slowly fucked Blake. His cries devolved into grunts, his voice deepening as his body's extreme hormone production began to take over. He felt his muscles tighten and thicken slightly. Next, he felt his mind slip away as the primal feelings of sex took over. Blake began to sweat profusely, and although he couldn't notice it, the room was filled with a thick musky smell, intoxicating to anyone who encountered it, as glands in his pits and crotch worked overtime to pump out pheromones into the air. Blake noticed a few hairs begin to appear on his chest; the testosterone was tightening its control over his body. The images of muscular hunks on the screen in front of him were pleasing, but a huge wave of lust took over his emotions. The dildo in his ass, fucking him hard and fast, now, wasn't enough. Just a few minutes ago even the slow pace of the machine was nearly too much for Blake to take, but the hormones now controlling his body craved even more. His cock was fully erect, 6.5" inches of thick meat pulsing and trying to grow larger. From the control room, Sampson watched Blake's body stressfully trying to grow. It was apparent that Blake's body was pushing itself to the limit, trying to produce muscle and tissue to grow bigger as his balls churned and worked overtime to produce more and more testosterone, and cum. "He seems to want even more," an intern commented, looking up from a computer screen collecting and collating all of the biosensor data into a summarized chart in real-time. "We're already at the highest speed and intensity," Sampson commented. He turned toward the internet, a 5'7" guy with light brown hair. "We'll leave him at this setting for a while, and in the meantime, we'll need to figure out something else to stimulate him even more for the next experiment. Max, can you start making plans?" Max the intern nodded. He was a pretty athletic guy himself, although he paled in comparison to Blake even before sex with Matt grew his muscles. Max was curious about how much more stimulated Blake could be, and what the results would be. The stud downstairs was already a primal sex beast, craving more and more- wait. Max grinned and had an idea. "Sir, if we're leaving the subject on this stimulation level, can I step out for a moment? The computer will collect the data automatically." "Yes, go ahead." Max nodded and exited the control room, bringing his universal access key card with him. As he hurried downstairs and into the hallway, his heart rate soared and his cock twitched at the idea of what he was about to do. Max approached the door of exam room, which was sealed tightly and had a red "IN USE" light angrily forbidding access. Max gulped and inserted his key card into the door, then typed the four-digit override code. Blake's bestial screams were muffled by the door, but Max heard the grunting and howling and became very turned on. The door shutter quickly rose to admit him access, then slammed behind him loudly. Blake screamed, "FUCK YEAH, I NEED MORE!" at the top of his lungs, as he intently glared forward at the porn projected on the screen as the huge dildo was relentlessly pounding his ass. Max took a deep breath, and at the instant Blake turned over and saw him standing at the door, he inhaled a massive dose of pheromones. "Holy fuck," Max muttered, instantly intoxicated by the smell. It was like a drug... the feeling of it was so intense, he was overcome with a desire, not just to enjoy more of the smell, but to get to the source of it and completely immerse himself in the masculinity it represented. Max instantly ripped off his shirt and pants. His 5" cock was fully erect, pitching a tent in his tight briefs. Blake moaned and howled, crawling away from the dildo machine. He stood upright, his cock now swollen to 7.5" and muscles nearly double their size when the test began. Blake ran over to him, and the two began making out, their cocks pressed up against each other. From the control room, Sampson slammed on his desk in rage. "HOW DID HE GET IN THERE! I told you I wanted the door locked and un-overrideable!" "S-sir... it's a safety precaution. We can't fully shut ourselves out from the exam rooms," stammered another intern. "Fuck! We weren't ready for testing with another man yet!" Back in the exam room, Blake was now lying on the table, the dildo machine pushed away, its purpose fulfilled. Max was on his hands and knees above Blake, his muscles and cock thickening and growing slightly, now 5.5", dangling over Blake's face. His own face rested in Blake's crotch as he sniffed and inhaled straight from the source of Blake's musky scent. Max ran his tongue up and down Blake's huge shaft and across his balls, slurping up sweat and precum. After some teasing, he wrapped his head around the tip of Blake's cock, slowly sucking on the huge meat, unable to take even half of it into his throat without gagging. At the other end of the table, Blake was sucking Max's cock furiously, deepthroating its entire length, feeling it grow and lengthen in his mouth. The two men were obsessed with each other, unable to stop having sex even if their lives depended on it. After some time spent 69'ing, Max stood up and grabbed the bottle of lube, which had been knocked to the floor in the commotion. He furiously lubed up his ass and Blake's cock, then squatted down and pushed as much of it into his ass as he could. The men fucked for a while, Max impaling himself with Blake's massive member, riding the dick with abandon. All the while, their bodies were producing more and more testosterone, resulting in a huge increase in muscle size. Max, who looked pretty strong, but nothing too out of the ordinary, now looked like a huge stud, definitely the strongest guy at any average gym. And Blake, who previously was a huge guy, was now resembling more of a giant muscle god, 7' tall and over 275 lbs of pure muscle. Finally, Max and Blake couldn't take any more, their bodies begged for release. Before getting up off of Blake's cock, Max unleashed a massive load all over Blake's chest, squirt after squirt of hot seed coating Blake's pecs, abs, shoulders, and face with white cream. It pooled up in the crevices between Blake's muscles and looked incredible. Blake lifted Max up off his dick, commanding him to kneel on the floor. The smaller man complied, and Blake unleashed an even larger torrent of his jizz all over Max, the force of which was almost enough to send him recoiling. The cum hit him with the force of a super soaker, spraying everywhere and pooling up on the floor. Blake screamed and yelled as load after load came gushing from his massive cock. Max, who got a little taste of cum from one of the earlier blasts, was positioning himself to be hit and covered with the most cum possible, and after Blake's orgasm had subsided, he was greedily licking his body, the floor, and Blake himself for every last drop of cum. There was far too much for him to finish, so he resorted to lying down on the floor, covering himself in it. Blake laid there with him, embracing his partner and kissing him intensely. The two men's muscles slowly shrunk, but settled on a resting point still quite a bit larger than they had begun the day with. Blake's cock, before softening, was around 8" long, having begun the day at only 6.5". Sampson surveyed the room from the control area. "Jesus Christ," he commented. "This is much more intense than we could have imagined." He commanded the interns to cycle the room's air several times before entering, incase of any lingering hormones, then to collect the now unconscious men and separate them into two different recovery rooms. "We have a lot of work to do," he concluded. Author's note: Dang, this was a hot part to write. The next part of the story will turn its attention to Matt, who's been changed in more than a few ways since his experience with Blake.
