“Um…how are we supposed to piss in these things?”

Several other hands dropped down. It was the first question Harold had expected, of course. “That’s rather easy–you simply piss through the uniform. Who has another question.”

“Wait, if we piss through it, all day long, and if we can’t wash it or take a shower, then…” the young man paused, hoping the rest of the question would be clear, but Harold motioned for him to continue–he wanted to hear the young man say it. “Then won’t it…be kind of dirty?”

“Yes, it will. That’s the purpose of the uniform.”

“No way, fuck this shit–I’m cutting this thing off,” one of the other men said, and stood up, heading for the kitchen, and a knife.

“Now, I feel a demonstration would help make this a bit clearer. After all, now that you are all dressed, I can demonstrate the purpose of this study. Come up here, and tell me your name.”

He wasn’t quite sure what made his feet veer off from his intended direction, but the stocky young man made his way to the front and stood by Harold. “My name is Adam.”

“Alright Adam. Now–I’m sure that your desire to remove your uniform was driven by the fact that you need to piss like a racehorse, don’t you?”

Adam nodded, though admitting the fact in front of his housemates made his face flush red.

“Well, go on then. Piss.”

“Right here?”

“Yes, right here please.”

“But I don’t want…to?” he said, only noticing that his cock had obeyed the professor already, and a stream of piss was arcing out the front of his jock pouch–well, spraying, was a bit more accurate, perhaps. Several men in the front scooted back to avoid the piss, and while Adam tried to stop himself, he couldn’t.

“Now, it is my hypothesis, that the dirtier a jock behaves and becomes, something happens to his brain chemistry,” Harold said, passing his hand through the spray of piss, and then slathering the wet hand across Adam’s face and hair. “They begin to lose access to their higher mental functions. They become more and more obsessed with perverse, filthy behavior. Their bodies put out copious amounts of musk, they desire one another’s stink and piss, they find themselves obsessed with fucking and masturbation.” He stopped, and adjusted his watch a moment, “In short–at the heart of every jock, I believe, is a filthy perverted animal, which can be unlocked by forcing that jock to become filthy, by forcing them to debase and humiliate themselves in front of their fellow jocks and the outside world. That this true jock is shameless, a complete faggot, hungry for cum, piss and sweat, their only desires in the world are working out, perving out, and wrestling and fighting their fellow jocks for dominance.”

Adam’s piss had slowed to a trickle, which was now running down his inner thigh. He licked his lips, tasting the piss left there by Harold’s hand, and shuddered, a dribble of precum leaking out the head of his cock. He tried to stop himself, but he started rubbing the pouch with one hand, groaning and snorting, switching hands to lick the piss and precum from the first. The rest of the house stared on in horror. “As you can see, Adam is one of these jocks, as are the rest of you, I believe.”

“I’m not…fucking like that. That’s fucking disgusting,” another man said, but everyone could hear the tremor of doubt in his voice.

“That’s what the experiment is setup to find out,” Harold said, “But I assure you, my hypotheses are never wrong. Reality has a way of…working out in my favor, right Adam?”

With a grunt, Adam’s cock started leaking cum through the pouch, and he smeared it back over the fabric. He didn’t know what was wrong with him, or why he couldn’t control himself. The…stink was opening up something deep in his mind, something he’d never known was there. He could smell the piss soaking into the carpet, and he dropped to his hands and knees, sucking it up in front of everyone. Some in the front, who could smell the piss, had begun rubbing their own cocks through the mesh pouch prisons, without even really noticing–imagining that it was them, there, instead of Adam, thinking about whether than piss might taste as good as it smells.

“Now, any other questions?”

One more hand went up, tentatively, “How, uh, how are we supposed to have sex, like this?”

“Oh, well, in your new uniforms, you are, of course, unable to penetrate anything. That said, you are free to frot as much as you desire on one another. Demonstrate, if you would, Adam.”

Unable to resist, he crawled forward to the nearest jock in front of him, and began rubbing his cock on his housemate’s thigh, groaning and grunting as he did, the other man disturbed, and yet…incredibly aroused by the sight.

“You are, of course, free to pleasure one another orally, and many jocks find themselves…desiring anal stimulation, as the process progresses. I imagine many of you will likely come to desire one another’s fists deep inside of your assholes, as the study continues. This kind of desire is completely normal for jocks like all of you, who are all rather…submissive creatures, in nature.” He saw one or two men’s hands slip between their thighs, poking and prodding at their hole, already accepting the suggestion as fact. “Now, I fear I must get going. A work crew will be here in an hour or so to install cameras throughout the house, but none of you will notice a thing out of the ordinary, and will behave as though you are not being observed. I leave you jocks to it! I hope you all deeply enjoy your journeys of self discovery.” With that, he left–even more thrilled. This was going to be a very fruitful experiment, he believed.

Within five hours, every jock in the house had piss through their new uniforms, and all of them found themselves in positions similar to Adam’s–new desires were welling up within them, and very few found themselves capable of controlling themselves for long. A small orgy erupted in the living room, when some of the jocks gathered to discuss a way of escaping…but found themselves too distracted by the scents of one another to resist their new, inner urges. Other’s resisted, as best they could…but no one in the house believed that the jock within them would remain dormant for very long.
