Jon ducked into a bathroom to get a better look at his new rack. It took him a few minutes to figure out how to get his top off, and he struggled with his new bra, but he managed to to toss both to the floor to gaze at his new tits. They were, somehow, even more pale than his arms, with his light pink nipples pierced with black barbells. A pentacle tattoo was just above his left breast, and what looked like a crow was on his collarbone above his right. He didn't notice any other tattoos, but he was a bit distracted by how his chest moved as he turned around. Jon could feel himself getting turned on at looking at his tits, his pussy slowly growing more damp as he stared. It reminded him that he needed to get rid of this probable pregnancy problem.
As he was getting his clothes back on, he heard the bell ring. School was letting out, and if he left the bathroom now, odds are he'd bump into someone and get their bottom half. Remembering his plan, Jon ducked into one of the stalls, locking in behind him. All he had to do was wait about 30 minutes, and things should be clear enough for him to make his move.
Sarah was desperate after her cheerleading practice. Her morning quickie with Biff had been good, but it wasn't enough for her. As much as she loved eating Biff's pussy, she still needed some cock in her life. It didn't help that her friends LaTanya and Alejandra were all over each other during practice, and even more in the showers afterwards. The two of them were at full mast the entire afternoon, and it was driving Sarah mad. As she stepped out of the girls locker room, she could swear that she heard the two of them giving each other a hand job. As she considered going back in to see if they'd let her join in, she was knocked off balance by Jon, swapping their bottoms.
"Watch it, freak", she said, as she braced against the wall to keep from falling over.
"Sorry, didn't see you", Jon said. He turned, his black peasant dress swishing as he rushed down the hallway. What a loser, Sarah thought, even though he does have a great set of tits.
She then heard Alejandra yell "Oh God, suck my cock, babe!" as the door to the locker room opened up. One of the other captains, Leslie, was just leaving, a look of disgust on her face.
"I can't believe those two. I mean, in front of everyone? I get that they're an item, but it doesn't mean that they can suck each other's dicks in front of the whole team!"
"I know, right? At least go to the abandoned lab for that kind of thing". Sarah replied.
Leslie gave her a knowing smile, and nudged her with her shoulder, causing them to swap top halves, Leslie now had Sarah's, formerly Karyn's, tits and dress sense, while Sarah now had Leslie's much flatter chest.
The two girls wished each other a good weekend, and after Leslie turned the corner, Sarah went back inside the locker room, seeing if the two girls needed an extra hand.
Karyn was laying in bed, marveling at her handiwork when her cell rang.
"I made the swap" Jon said.
"Awesome? Who's eggo did you preggo?"
"Sarah"
"As in, head bitch cheerleader Sarah?"
"Yeah, I'm rocking her cunt right now. I can't wait to get back to you to try it out. I will say, it goes great with my new tits".
That made Karyn sit up in bed, her already erect cock growing harder. "Seriously? I can't wait to see them!"
"I think they belonged to that one goth senior, what's her name..."
"Morgan?"
"Yeah, her. Anyways, I'll be over in a few minutes. It's hard to run with tits this big".
Karyn hung up her phone, a giant grin spreading over her face. Her wishes had worked. She stood up, once more to admire the changes she had made to her new body. She was still the same height, and she still had Sarah's tits and Biff's cock, but everything else had been reshaped to match Sarah's former measurements. Hairless legs, plump feminine ass, and a rock hard cock; just how she wanted it. Just looking at her reflection, her manhood nearly reaching between her breasts, made her all the more eager to see her boyfriend's new additons. After Jon had left, Karyn had used the rock to guide the right people to where they needed to be, so Jon would end up being the same person from the neck down. She had chosen Morgan because, prior to wishing herself bi, she had always admired her personality. Now that she was into women, she also admired her body. And that body now belonged to Jon. The fact that getting Morgan's body for Jon also meant that Sarah ended up pregnant just made things more fun. Karyn wondered how Sarah would break the news to Biff that she was having a baby. That'll show those two, Karyn thought.
Jon was doing his best to loosen up his dress as he raced up to Karyn. The knot was in an awkward place, and he couldn't quite reach it before he burst into her bedroom. Karyn was laying on her side, facing the door, her cock ready to burst.
"Help me get out of this dress", Jon said, "I need a cock in my cunt".
Karyn spun him around, unlacing the back of the dress, kissing his neck as she pulled his blouse down over his breasts. Jon moaned in delight, loving the feeling of her large dick poking him in the back. With one last tug, Jon's dress and blouse fell to the floor, quickly followed by his black bra, and his matching panties. He turned to face his girlfriend, giving her a good look at his tits for the first time. Jon could see the fascination in her eyes as she started kneading his breasts. It took everything he had to not collapse onto the bed immediately, her ministrations were that good. Jon reached down to play with his pussy, noticing for the first time that his new clit was pierced, as well. Karyn started to suck on one of Jon's nipples, which finally pushed him over the edge. Jon shoved his girlfriend onto her bed, straddled her hips, and lowered himself onto her cock. Round 3 had begun.
