Not wanting to expose himself too much but still curious Jon opened his pants and let them slide down his legs. He looked at the smooth front of his tighty-whiteys in semi-shocked disbelief. He had know that the wish would work but it was still strange not to see the familiar bulge in his underwear.
As much out of pain at the sudden appearance of Jon's genitals in her pants as curiosity Karyn quickly dropped both her pants and panties to the floor and stepped out of them so that she wouldn't trip. She looked down at her new penis and stroked it gently with one hand. "Oh! I can feel it getting hard." she said looking up at Jon.
"You can what?" Jon said looking up himself. What he saw before him was another shock: Standing their, in his bedroom, naked from the waist down and playing with her penis was the girl of his dreams, the girl he had had a crush on since the fourth grade and all he could do was stare with his mouth hanging open.
Noting the awed expression on Jon's face Karyn giggled before saying, "Why Jon is that look for little old me? Does this mean that you have fantasies about me? Do you think about having sex with me? Do you think about having sex with me right before bed? Do you touch yourself while thinking about me? Come on Jon tell me the truth." she said with a wink and an expression so hot it could melt steel.
Jon couldn't do anything but stammer as Karyn walked over to where he was standing and put her arms around him. She drew him into a long passionate kiss that seemed to go on for a blissful eternity. As she pulled back from the kiss she looked him in the eyes and asked again, "Well Jon is that what you think about when you touch yourself?"
He hardly knew what was happening suddenly Karyn, who had never even hinted that she found him attractive had surprised him with a kiss. Jon didn't care why he just didn't want it to end, so he did the only thing he could think of: he answered her, "Yes. You are the only thing I ever think about, I've never fantasized about any other girls. Just you." His confession complete he leaned in for another kiss that lasted as long as the first.
Karyn had known for years that Jon had a crush on her, the truth was she felt the same about him but was afraid that if they got into a relationship it might have consequences for their friendship. But ever since the wish to swap genitals that hadn't mattered to her anymore. Now she felt free to do what she had always wanted to do. Without breaking the kiss Karyn let her hand slowly drift down his back to rest gently just above the top of his underwear. She slid her hand down into his underwear and caressed his naked ass.
Jon gave a little moan of pleasure at her touch and kissed her harder. Then he felt both of her hand on his hips and before he knew what was happening she had pulled him underwear down and let it fall to the floor. Jon, trying desperately not to break the kiss, stepped out of his pants and underwear. He put his arms around Karyn and caressed her butt pulling her toward him. He was startled for a moment when he felt her penis press against his belly but the moment quickly passed and he kissed her even harder.
Breaking apart just long enough to remove their shirts and for Karyn to remove her bra they made their way back over to Jon's bed. Karyn sat on the edge of the bed and with no encouragement from Karyn, Jon sat on her lap with her penis pressed up between them. Raising his hips up a bit Jon was able to rub the head of Karyn's rock hard penis again his own quickly dampening crotch. He nearly jump off her lap entirely, the first time the tip of her penis rubbed against his clit, it felt so good. Before he knew it he was getting a rhythm with the tip of Karyn's penis rubbing his clit at the top of each motion and then sliding down it again being careful not to let it get anywhere near where he was pretty sure his vagina must be.
She could hardly take it by this point. Karyn had to have Jon now! With a feat of strength that surprised both of them a bit Karyn pulled Jon onto the bed and rolled on top of him. The look of surprise on Jon's face made Karyn hesitate for a moment. Then he said, "Do it. I love you Karyn. Fuck me, I want to feel you inside of me." Karyn didn't need any more encouragement than that. She thrust her penis toward Jon's naked crotch, prepared to deflower her best friend and bring both of them untold pleasures.
