Knickers? By Rhodry

Both brother and sister, where effect by a strange energy that suddenly enter the room. Both Michael and Rebecca, suddenly switched bodies.

They were both shocked and surprised. Each one complained that, never truthy understood the other sex.
So they looked at it as benefit or experiment.
So they send up some ground rules.
No sexual acts that either one would do.
No embarrassment as each other.
You must respect the body you are in.
So Rebecca follow, Michael in her body. passed out. It was like he was partly in her body. He passed out in unflattering position on the coach.
She decided to let him sleep it of.
She decided to wait until morning, until talking to her brother, it seems to that he had to much to drink, and knew that she never really drank much. But Michael thought he could handle it.
How she knew that he he was fooling around, that his underwear was missing beneath his dress. He will have explained much. I knew he probably wanted to do it.
