Brent walked to his locker to get dressed, gently laying Jake's cock down on the bench next to him. Brent felt a tingle run through his body and watched as his muscles became more defined, his body fat disappeared, all his body hair except a small patch above his dick disappeared, and a tribal tatoo appeared around each of his biceps. Brent couldn't help but think how hot he was now. He finished getting dressed, his clothes now tight and showing off his body and grabbed his bag. Before he placed Jake's cock in his bag he sucked it a moment, delighting in the taste and the sounds of Jake moaning from the shower.
Brent went to find his girlfriend, Sarah. After looking for her for 15 minutes he found her outside, apparently skipping her class, talking with friends. "Hey baby!" she said, throwing her arms around Brent's neck "You seem bigger, did you just finish working out?"
"Yea, something like that. Hey you wanna come see something?" Brent said with a wink.
"Oh, you're bad. But okay!" Sarah said, playfully slapping Brent's chest. The two of them walked to a Janitor's closet and went inside. They started to make out, Brent had to think about kissing Jake to keep himself from feeling sick.
Brent had Sarah lay back and spread her legs, she pulled down her shorts and spread her legs exposing her wet pussy. Brent tried to keep from looking completely disgusted, but Sarah saw through it but tried to ignore it. Brent reached into his bag and pulled out Jake's cock.
"Oh you got me a toy" Sarah cooed, trying to make herself sexier.
"Well, I think we'll both enjoy it, but first lets slick it up a bit." Brent took Jake's cock and began sucking on it under the pretense of lubing it up. He stopped after a moment when he realized Sarah was giving him an odd look. He pulled Jake's spit slicked dick out of his mouth and pushed it into Sarah's pussy, Brent trying so hard not to gag at the sight of her vagina.
Brent quickly fucked her with it, until in a short amount of time, Jake shot his load in her. Sarah's shoulders widened slightly, he hips narrowed a little, her breasts shrank slightly, and her features became a little rougher. It wasn't a big change but it was definately noticable to Brent. "Oh Brent that was very . . . niiiiccccee" Sarah began to moan again as Brent began to fuck her again.
He felt a slight tug from the cock in his hands. "Must be trying to get back to Jake," Brent thought, "Better hurry with this." Brent picked up his pace, and within a minute Jake's cock shot another load. Sarah's changes progressed further, her voice becoming deeper, her body growing in size some.
"What's going ooooooooooonnnnnn" she started moaning again, as Brent never even hesitated to keep on fucking her with the cock. 20 minutes later Brent pulled Jake's cock out of her pussy, the cock now slick with juices. Sarah's body had now completely changed and looked like a man's except she still lacked a penis. Brent remembered what had happened to Gary and Josh when they sucked Jake's cock and hoped something similar would happen when Sarah did.
"Now you need to lick your juices off his dick" Brent said pushing Jake's cock against Sarah's masculine lips. Sarah took the cock into her mouth and began sucking on it. Jake dumped a load down her throat but she kept going at it, even while her clit swelled into a 6 inch cock. Another load and a pair of balls dropped sealing her vagina and growing her, now his cock to a respectable 10 inches.
Brent pulled the cock away from Sarah, "Oh my, you're fucking hot now!" Brent's cock was now making a noticeable tent in his jeans.
"What did you do to me?!" Sarah yelled in his deep voice.
"Well I'm gay now, and this seems to have worked out great for me" Brent said with a smile on his face, feeling the tug on Jake's cock continue.
"Well, I don't know how to tell you this but, I don't like men like that anymore."
"That's ok I can fix that, though we need a new name for you, how about Sam?"
"It works, but how are you going to fix it?" Brent replied by grinning and taking Jake's cock, still wet with spit and slowly penetrating Sam's asshole. Sam moaned loudly at the new mix of pain and pleasure. Brent quickly fucked Sam until Jake's cock emptied another load into Sam's ass causing Sam's own cock to shoot a massive load, without him even touching it.
Sam's body shifted some becoming more muscular and losing what little body hair there was. A small tatoo appeared on his left pec of a triangle pointing down with a rainbow patter inside. Sam's conversion from Sarah was now complete. Brent gave Sam his boxers as none of Sarah's clothes would fit him, and they headed back for the lockerroom to get some more clothes.
