An in-genie-ous wish

"Let's see what else the rock can do," said Sarah, and she got up and picked it up. "Sarah, please be careful," said Jon. "Look at what we've done already with that rock!" "I know what we've done. We've had the best hot, wild sex I've EVER had! I'm seeing you in a whole new light, Jon-Boy! And I like what I see!" "But Sarah ... " "Don't worry, Jon. I'm not going to misuse it. You gave me just a good time right now, I could never do anything mean to you. I'll use the rock for both of us. I'm now your very own little genie." "You're not a genie, Sarah. It could be very dangerous if you weren't careful about how you use that rock." "Quit worrying! Just do as I said! I said I would be your genie, and I wish you'd let me be just that!" There was a puff of smoke. The rock was laying on the floor and, beside it, was a very exotic looking bottle.
