Keith felt the hunger in him growing, as he watched Jacob at the urinal. He quietly walked over to where Jacob was and waited for Jacob to finish.
"Hey, do you mind I'm try to pee here!"
"No, I don't mind at all, now why don't you hurry up and finish" replied Keith. Jacob, apparently done, started to pull up his zipper, while turning away from Keith. Keith, being impatient due to the hunger, grabbed Jacob's hips and turned him around.
Keith took Jacob's soft cock into his mouth and began sucking on it. Jacob moaned "No, please don't. I don't want to be gay." As Jacob's cock rapidly grew to full hardness, Keith redoubled his efforts, feeling the need to drink the cum down.

Steve walked back from the gym, with his hands in his pockets, trying to hide the fact that his cock was rock hard. He was frustrated from his failed attempt to masturbate. He tried to think of other things, but his cock just wouldn't go soft. He was walking down the hall when he heard moaning coming from inside of one of the men's restrooms.
The sound was turning Steve on, because it was obviously a guy moaning. He walked into the bathroom, and saw Keith on his knees in front of Jacob, sucking him off. Steve was so turned on by the sight he started to rub his cock through his shorts, though he wished that he was the one on the ground sucking Jacob's cock. "Wait, what am I thinking?" Steve tried to clear his head, but he couldn't deny that he wanted to suck a guy off and badly.
Then Jacob started to shoot into Keith's mouth who gulped it down. Once he finished shooting, Jacob's eyes started to close, and he lay down on the bathroom floor, shorts still open and drifted off to sleep. Steve thought that the scene was the hottest thing ever, but despite his stroking he just wouldn't cum.
"Hey, Keith!" shouted Steve, having tucked his cock away for now. Keith looked up shocked and preparing to flee. "No, wait. I need you to tell me what you did to me."
"I . . . sucked . . . you" replied Keith meekly.
"No, not that there's something else. It's my cock, it won't go soft, and I can't cum, and I can't stop thinking about sucking cock. I need to know what you did to me, maybe we can find a way to undo it."
"I don't know what's going on. I pulled on these briefs after you guys took mine, and now I've become more muscled, my cock is gone, and I can't help but suck cock. Its like a hunger."
"Can't you just take the briefs off, maybe that would stop it."
"I tried its like they're stuck on me."
"Wait what about him, what if he changes too." Steve said, gesturing to Jacob. At that time Jacob happened to be waking up. He stood up, his cock still hard and leaking.
"What's going on guys?"
"We're not sure" said Keith, but Steve was too busy staring lustfully at Jacob's cock to notice. Almost on auto-pilot, Steve walked over to Jacob and started sucking his cock. While he sucked on Jacob's cock, Steve reached down and pulled his own cock out of his shorts. After only 15 seconds of stroking Steve started shooting cum onto Jacob's legs and shoes. Steve kept up his work on Jacob for another couple minutes before Jacob pushed him off.
"You're not doing it right" said Jacob who started stroking his cock himself. After a minute Jacob started to look frustrated. Jacob looked down at Steve's still hard cock and bent down and started sucking. Much like Steve, once Jacob had a cock in his mouth he blew his load quickly. Finally satisfied they both stood up and cleaned the cum off their legs.
"You know its odd, I don't feel hungry for either of you guys' cum now" said Keith.
"Maybe it takes time" replied Jacob.
"Well thats the thing, I kinda wanted to join in, but it was an overwhelming need like before." Keith walked over to the mirror noticing even more muscle mass. "This all started with these briefs, we need to go see if we can find someone who knows anything about them."
