Jon felt himself turn back to human with a kiss. There was also a breeze on his body, probably from the air conditioner, and he was kissing himself. He wouldn't have made the initial wish if he hadn't wanted a little sexual experimentation, but he hadn't quite expected this. Jon kissed his double back, lips and tongue touching identical ones.
"Let's do it," he said, after stopping for air. Jon reached into the lap he was sitting on and made it clear what that entailed, as he unbuttoned the other Jon's pants. But he hesitated. "You're a guy," he said.
"You're a guy!" replied the other Jon.
"No, I'm not, I have a pu--... no, I see now. As far as you're concerned I'm a normal guy since it's your body and it's normal for guys to have pussies here, and you're a normal guy to me since it's my body and the penis is normal for me." He continued to unbutton the other Jon's pants, and got to his feet. The other Jon soon did too and Jon helped him pull off his pants and then strip the rest of the way.
They looked each other's body over from top to bottom. Jon was the first to speak up. "We're both guys, except we're not. Each of us thinks we're part female and the other one is a guy."
"We could swap again?" offered the other Jon. "If we're in our own bodies we'd be normal and the other person would be part female."
"I never thought my wish would lead to...."
"Me neither," said Jon. "I wish for guys and girls to swap, I expected it would be just our private parts and if I did have sex the other person would be female everywhere else. But you're 100% male."
"You're 100% male," said the other Jon.
Jon picked up a coin. It had fallen out of the other Jon's pants pocket at some point. "We're not going to figure it out by talking. Heads we swap back first, tails we don't. Okay?"
"Okay!"
