Back to normal?

Getting down as low as her rubberized frame would allow, she half crawled, half dragged herself around the foot of the bed. She reached up to grasp the stone...
... it was there, where it should have been. Clutching the magic rock in her hand, she made the reverse journey in half the time, slipping out of the door to the sounds of her mother grunting in climax. That was something she didn't want to have to hear again!
Back in her bedroom, Jon was pacing back and forth on his own heels, becoming even more aroused as he felt the lining of the leather skirt caress his smooth thighs. each step reminded him that he was a guy, wearing forbidden clothing. Each swish of the nylon lining against the sheer stockings sent a tiny shiver up his spine. Everything about his outfit turned him on. Yet at the same time, he knew that it was wrong to wear it and that he should be planning to do something about it. When Karyn slipped back into the room triumphant, he was still so wrapped up in running his hands up and down his slim waist and rounded hips that it took him a few moments to come back to reality.
"Hhhuuttt Hhhuuummm! Having fun are we?"
"... Aaahh Yeah, sorry, just got a bit carried away there. Man, did that feel sexy!"
"Yes, I can imagine. I mean, I really can imagine! I'm so wet now that if I wasn't wearing rubber, I'd be in a pool about a foot deep in here. Anyway, Here, I got your stupid rock. And you owe me one, I had to see my parents getting it on. Apart from the fact that my Mum is part guy and my Dad looks like a cute teenaged girl, just the fact that my folkes were doing it is just way too wierd!"
"Yeah, I know what you mean. Oldies doing it is just wrong! So how about we get ourselves fixed up before your mum finds out she has lost the rock?"
"Sound good to me. How are you gonna reverse it?"
"Hhhmmmmmm, Maybe since all the previous wishes are time limited, all we have to do is change the time. Make the three months into three minutes and we should already be changed back."
"Well, it's worth a shot."
"OK, her goes, I wish that..."
