She knows how to pick them. By Rhodry

Simon hated it, he really hated it. Why because of several things, one she just as smart as he is, two besides her brains and she was beautiful too. Three she has a talent, a ability which Simon doesn't have.

How she discovered or knew she had this ability that is another story. How it I know, well that is a longer story too.
Why when his sister decides to have a romp in the sack with guys, she might like want to see or not. But sometimes, sometimes they want to see her again. Or do it again with her.
But sometimes either she not interesting in them really, want to do it. But want see her again.
So she decided to used his body for a day. And Simon gets to play her sister and gets her left-overs. Her second time over. Which for Simon as his sister, it experience the first for him. Or for him as her. To have carnal sexually experience as her.
She believe he hated it. When she decided take a day out as a she and be him for a day.
Simon is beginning to enjoy his time as her. He wondered why him, why not some one of her friends Or was it, she wants to keep it secret to them. The question is that could I do it too. If I can't why can she do it?
