Touch yourself." Mommy I don't know....." Came her feeble voice, not sure."Do it for me baby. Show mommy what a hot girl you are."At first she hesitat...d. But slowly she began to rub her pussy. Touching her cunt lips and then up to her clit which brought about a whispered moan. It was then that I knew that I had her.Faster she rubbed her pussy. Down to her asshole then up to her clit."That's it honey your doing it so good. Play with yourself baby. Show mommy how sexy you are."Her mouth was open. The water covered any noise we would make. She was very noisy this time. She was very vocal, urging me on as I fucked her. She was a different woman now. I grasped her hips and fucked her hard. I was afraid my pounding would cause one or both of us to slip, but she kept urging me on with cries of ‘Deeper!’ and ‘More!’ and ‘Harder!’ I was fucking her with abandon now, and I started to make noises as well. She squealed and yelled when she came, totally uninhibited. Since I had cum twice already. Then held it to her as she humped it a couple more times and then just lay still saying how good it felt. It did not take long to recover and teach him more, this kid was going to have so much experience by the time she was done; he would be able to please any women. Jeff tried not to think too much about his own cock because he really did want to know, all there was to learn, or she could teach him. Now she was resting so Jeff was just lying there. "You Brad Daley?" asked the Truancy officer flashing his badge.He was well known around our school as a right scumbag."Yeah," I replied with a sinking heart."Been hearing things about you and your sister," he smirked."Yeah what sort of things," I asked trying to sound brave."Things that brother shouldn't be doing to their sisters," he said with even a bigger smirk.Shit that Neil could never keep his trap shut."Looks like you going to get thrown out of school and a lot worse too," he said,.
