The thoughts had crossed his mind when she wore her skimpy bikini in front of him."I .. I .. No .. perhaps occasionally .."Lisa smiled and looked into...his face,"I am going to kiss you Aron."Aron saw her sister's face coming nearer to his and his first impulse was to shift his head away but Lisa's hands gently head it. Their lips touched and Lisa ran her tongue across her brother's closed lips. Aron felt the tongue slipping inward between his lips and closed his eyes as strange, new sensations. We passed to each other our telephone numbers. He did not take long to call me and invite me to visit him at his house, where he was alone. I accepted. When I got there, he was in bed watching erotic movies on television.

I started to kiss him all. I Squirmed around as I came down from my orgasm, before I passed out.I woke up in the morning with my hand still in my crotch! I got dressed quickly in my dress and ran off to school.It was still hard being in school thinking about the night before. Very time I thought about it my pussy would spasm.In school I wasn't very popular, I guess that I was one of those not bad looking girls, but with brains, and that doesn't buy you lots of friends. SO I didn;t have lots of poeple to talk to to keep. "Your plaything?" I stammered out, not knowing what else to say. "Like, sexually?" "Of course, sexually, silly" she said, the sultry smile suddenly getting exchanged for a more innocent-looking one. "There's a bunch of stuff I've been hearing about from girls at school, but haven't had a chance to try out myself. This should be a good chance for me." Like, what do you have in mind?" I asked hesitantly."Oh, all kinds of stuff," she said, lying down on the bed. As she did, I could see her skirt.
