Suddenly a girl appeared in front of Jon, out of thin air. There was something that looked very familiar about her. Then Jon realized it--the girl was wearing Jon's own robe and looked very similar to him.
"Who are you?" he asked.
"I'm you," replied the girl. "From a little bit in the future. We have to have sex now. Because I desperately want you!"
"What? What?"
"You wished to fuck yourself. So this is what happened! It's better than what could have happened if the stone wasn't so nice about it."
"Wow," said Jon. Not thinking, really, he undressed and helped the girl off with her robe. He kissed her and found her eager to kiss back. Looking over and feeling the unfamiliar body with him he suddenly heard the girl say "No, not there. Put your hand between my legs first and..." There was a lot Jon still didn't know about sex and the girl had to explain things to him. After a session of heavy petting they had full sex and Jon lay back, unable to believe it was so good.
Then Jon felt his body begin to twitch as it reformed into a new shape. He knew what was happening, as his breasts inflated and his genitals re-formed--he was turning into a girl. Picking up a robe, he hurriedly threw it on himself before the room shimmered around him--her. Then the bed was made again, and things were normal--just as it had been a short time ago. In front of her was standing... himself! Feelings of lust completely unfamiliar to Jon filtered into her consciousness as the "other" Jon looked very hot in her eyes.
"Who are you?" asked the other Jon.
"I'm you," replied Jon in her new female voice. "From a little bit in the future. We have to have sex now. Because I desperately want you!"
"What? What?"
"You wished to fuck yourself," said Jon. "So this is what happened! It's better than what could have happened if the stone wasn't so nice about it."
"Wow," said the other Jon as he looked her over and helped her off with her robe.
The same scene happened, just from the other perspective, with Jon giving her earlier self all the advice she had received when she was in the male position. The orgasm felt like it covered the lower half of her body and was very much unlike anything she knew as a male.
When it was all over, the "other" Jon lay back on the bed, until his body began to shimmer. Suddenly, he got up, grabbed a robe and put it on, and vanished. Now there was only one Jon left. She had indeed managed to fuck herself after that wish, but now she was a girl. And while she didn't keep the overwhelming lust directed at her earlier self, she still did feel decidedly strange.
Jon wondered just what reality change the stone made--did people think she had transformed, or that she was a girl all along? And that strange feeling. Unconsciously, she found herself thinking of guys her age, but from a different point of view. Was she feeling attracted to them?
