Jon and Karyn made their way up to Karyn's room, both of them ready to start brainstorming. Jon took stock of her room, having been up there a few times previously. For the most part, everything looked the same, except that her tastes seemed to run a little more pink and frilly than before. She must have taken some more of Sarah's style than either of them were aware of. Before they could get started, however, Jon needed to use the bathroom. Excusing himself, he went across the hall and, remembering his new equipment, had a seat. He took a minute to look at his pussy and legs, actually taking them in instead of just staring at them. He had to admit, he loved how smooth his thighs were, and they did look great. His fingers brushed by his clit, sending a brief bolt of pleasure up his spine, causing him to shudder. Fuck, he thought, I could get used to that. After finishing up, and remembering to wipe, Jon took a good look at himself in the mirror. Just looking at his pussy was turning him on, and this time he started to embrace it. He felt his clit start to swell, and it took all his willpower to not start giving himself a hand with it. He eventually pulled his pants back up, When he came back into Karyn's room, he saw that she was holding the stone, a look of deep thought on her face.
After Jon left, and as she waited for her computer to boot up, Karyn took a look around her room. It looked like it normally did, but it was also vastly different from what it normally looked like. Having both feelings was headache inducing. She opened the drawer on her nightstand, reaching for what was a vibrator, but instead pulled out a fleshlight. Makes sense, thought Karyn. Thinking about Jon's new pussy, Karyn thought about what it would be like for the two of them to fuck, hesitating a bit since she never had a thing for vaginas, which Jon now had. Just thinking about Jon's pussy made her dick start to harden. Karyn made a choice. She reached into Jon's backpack and pulled out the wishing stone. She needed to make a few adjustments to help make this situation less awkward for herself.
"I wish I was bisexual". Karyn said. The stone glowed, and she felt something within her shift. As she opened her eyes, Karyn saw that her room was exactly the same. Checking her computer, she checked out a porn site, seeing how she felt. Suddenly being into both men and women was a bit odd, but Karyn had to admit she did enjoy the thought of her now expanded options. Suddenly the thought of having sex with someone with a pussy wasn't as much of a mountain to climb. Thinking about what else she would need, she wished up a box of condoms, not wanting to get her best friend pregnant. She only had one more wish to make, doing her best to word it properly so things wouldn't mess things up more than they already had been.
"I wish that, for the next four hours, that Jon and I would be uninterrupted by anyone, and I wish that, for the next four hours, Jon would be ready and willing to have passionate sex with me". The stone started to glow, with it only fading as Jon came back in to the room. Karyn also saw the glow fade from Jon's eyes, Karyn smiled, setting the stone down, and opened up her photo folder.
"So, I thought I could look at some old pictures, just to see how much reality has changed" Karyn said. Jon nodded in agreement, took a seat on her bed, and the two of them started looking. Karyn found some pictures from a beach trip the two of them had gone on with their families last year, taking in the changes. Jon was wearing a pair of hot pink bikini bottoms, his toenails matching the color, along with black flip-flops. Karyn was wearing a pair of camo board shorts, and a black micro bikini top, just barely covering her tits. She had to admit, it was a hot look. Her shorts started getting tighter, just bordering on being uncomfortable. As they went through old pictures, it appeared that, from everyone else's perspective, they had always been like this.
Jon was feeling stranger as he looked over Karyn's shoulder. For whatever reason, ever since he came back in from the bathroom, he couldn't take his eyes off of Karyn. He stood up to get a closer look at some old pictures, and when he looked down, he saw that Karyn was standing at full staff. And it was a very impressive staff. Mustering his courage, Jon decided to take a shot.
"You look a little uncomfortable", Jon said.
Karyn looked up at Jon, who was looking at her hard cock. With a smile, she said "Yeah, I kind of am. I haven't been able to get rid of this boner".
"Mind if I give you a hand?"
Karyn nodded, stood up, and pulled down her shorts, releasing her beast. Eight inches long, nearly an inch thick, Karyn's new penis was a sight to behold. For the first time, Jon felt excited about seeing another person's penis, and he made his choice. He took a grasp of her manhood, strangely enjoying the way it felt in his hand. As he worked her cock, Jon felt like it wasn't enough. He needed to do more, to have that rod inside of him in some way. Karyn was just enjoying the feeling of having someone else work her cock for a change, moaning in delight. She took off her cheerleading top, and undid her bra so Jon could finally see her new tits. She then took Jon's shirt off, and pressed herself into him, giving him a deep kiss.
If Jon wasn't turned on before, after the kiss, he was even more ready. For whatever reason, he felt like this was meant to be. Pulling himself away from Karyn, he gave her a devilish smile, and dropped to his knees. Karyn was confused, until she felt Jon's mouth on her cock. If she thought Jon wanking her was good, his mouth felt so much better. Jon spent time working the cock with his mouth and tongue, blowing her with gusto. It only took a few minutes, but eventually Karyn came, shooting her load into Jon's eager mouth. Jon had to admit, it wasn't as gross as he thought it would be. Swallowing the semen, Jon got back to his feet, kissing Karyn again, letting her taste what was left on his lips.
"That was incredible," Karyn said, "and I have to return the favor". She undid Jon's jeans, and pulled his pants and panties off. She pushed Jon down onto the bed, letting him lie back, so she could get a good look at his pussy. It was the first time she saw one from this angle, and thanks to her new sexuality, she was already starting to get hard again. Karyn got on her knees and started to caress his thighs, pushing his legs wider. She leaned forward and gave his clit a kiss, causing a shudder to pass through his body. Karyn took her time, kissing, then licking, Jon's womanhood, doing her best to drive him wild. She eventually started to use her fingers, gently easing first one, then two fingers into his gaping hole. Jon could barely stand it, moaning loudly as he rode Karyn's fingers. He looked down to Karyn, and the two made eye contact as she ate his pussy, and it was one of the hottest things he had ever seen, driving him over the edge to orgasm.
As he lay in the afterglow, Jon felt Karyn stand up and move over to her desk, grabbing something from a drawer. As she turned around, Jon saw that she was hard again. And he wanted that cock in his cunt. No, he NEEDED that cock in his cunt.
"Please, fuck me" Jon said, spreading his legs wide. Karyn smiled, wrapped her dick in a condom, and made her way over.
It took a few minutes of fumbling before Karyn and Jon got themselves into position, as neither of them had done this before, let alone from their current arrangement. Eventually Karyn ended up on her back, Jon on top, guiding her cock into his waiting pussy. Even with the condom on, both of them could hardly describe just how they felt. Jon felt like he was complete, that the fullness from Karyn's cock was all that he needed in life. He started to grind on the dick, moving his hips to Karyn's thrusts, eliciting moans from his best friend. Karyn was glad that she now had Biff's powerful legs, lifting Jon up with every thrust, enjoying what he was doing with his body. Jon leaned forward, kissing Karyn as they fucked each other, Karyn hitting all the right spaces inside Jon's cunt. He knew he wasn't going to last too much longer. And as Jon sat back up, Karyn thrusted deep into Jon, and that sent him over the edge again, causing Jon to cry out with a powerful orgasm.
As Jon came, he clamped down on Karyn's cock, and Karyn couldn't hold back any longer. She came, filling up the condom, and slipped her softening dick out of Jon. As they both laid next to each other, sweating and panting, they looked at each other. Jon was the first to break the silence.
"I think that was a great idea," Jon said.
"I think this makes us more than best friends," Karyn said back, cuddling with Jon as she yawned. "How 'bout a nap, then round 2?"
"I think I'd like that". Jon gave Karyn a kiss, then the two of them fell asleep, with thoughts of trying to fix their bodies the furthest thing from their minds.
