Just fooling about

Sarah hated the fact that because she is a girl, that she did know anything about cars. Sarah hated the fact that because she is pretty, she couldn't know anything about car.

So, she decided to swap bodies with her geek brother. So, she gets a better deal as a guy. Allan hated the fact that he has to be her. But not at same time to.
Why because, each time that Sarah thought, she didn't get a good deal because she is a girl. Some dealers were mostly guy and they either they could get lucky, or they could give the least good deal.
So, this time Sarah wanted a better deal for a car that she wanted. Allan was told that to stay here, and not to do something stupid or something I would do.
But Allan like the idea that, he was girl that he could get some information, on something that could help maybe?
After about 2 maybe 3 hours or more. Sarah as Allan returned home.
She was happy about her deal. But as she entered the house, she felt something wrong. Then she saw her top and slacks with her flats and the floor. Maybe Allan was playing dress-up the last couple of times. That Sarah borrowed his body. Then she saw her underwear there. As she entered the bedroom, she noticed that Allan and Sara's friend, Bethany were naked in the bed.
Sarah was shocked that Allan as her and her friend, were doing a lesbian/ bisexual bedroom games.
And Allan was surprised to see Sarah as him. And Beth always wanted to do it with her. It's not that Allan was playing dress-up as a girl. That he wanted to do with a girl as a girl?
