Before Jon could do anything, Jon reached out and stroked Jon's vagina.
"Hey, man, that's really hot!"
Jon wanted to stop Gabe from playing with his new "equipment" but something in him stopped him. He was enjoying it too much. Jon grasped Gabe's hand and thrust it deep inside him, moaning with pain and ecstacy.
Jon looked at Gabe's bulge in his pants. "Put it in me!"
Gabe stopped and moved his hand. "Jeez, man, I'm not gay!"
Jon grabbed the stone. "I wish you wanted to have sex with me!"
Gabe suddenly grabbed Jon around the head and thrust his lips onto Gabes. They kissed passionately, and Jon began loosening Gabe's trousers. He pulled down Gabe's boxers, and felt a massive erection in his hand. Jon lay on the bed, his legs apart, and Gabe lay on top of him. Gabe had a bit of trouble putting his penis in Jon's vagina, but with a bit of help from Jon, he managed it. Gabe thrust and thrust, deeper and deeper in Jon, as he cried out with pleasure as Jon reached his first orgasm. Gabe continued to thrust more and more, and then suddenly, Jon screamed with pleasure and it was all over. Gabe removed his still dripping penis, and then suddenly kissed Jon again.
"Let me do it again" he moaned.
"I'm fucked" said Jon
"I want to do it again" insisted Gabe.
Suddenly Jon realised what he had said. 'I wish you wanted to have sex with me' - but didn't apply a time scale to the wish!
Jon felt a strange glow, and he looked down - his ten minutes were up, and Jon had his old penis and testicles back. He looked up at Gabe.
"I want to fuck you Jon!"
Gabe grabbed Jon by the arms and threw him down on the bed face down. Gabe had once more gone fully erect, and was lying on Jon's back, his penis trying to find a way into Jon's rectum. Jon looked at the stone in panic - it was just out of reach!
