I slowly pulled him into me, kissing him lovingly as he probed my ass and pussy. With more thrusts, he moved his hand to my tits which were bouncing f...om the force of his fucking. He gently caressed them before moving his hand back down my torso to my legs. With one mighty thrust, he started rubbing my clitoris. I couldn’t believe it but as he ferociously rubbed my clitoris, his thumb in my ass and his dick powerfully thrusting, I started to cum again. This time, my juices were coating his. Surprisingly, none of it seemed all that bad. In fact, I was relieved that my son decided to participate more fully in my training. I had been worried I had pushed him into my BDSM lifestyle by exposing him to something he didn’t want to be a part of, and now he seemed excited to train me.I know that makes me sound like the worst mother in the world, and maybe I am.Approximately 1:00 P.M.Once the period was over, I started to head back to the gym and the locker rooms to change.

Then Alex said it looked like we'd be getting a show and I noticed things were getting more intense over there. The girl’s tits were out and he was kissing them. When I passed the blunt I noticed Alex’s hand resting on her crotch. The girl got on all fours, the guy pulled down her pants, pulled out his cock and started fucking her. Alex said something about this being a nice addition to the night, she seemed to. "She looks quite beautiful and you know it!" mom told him, "and itwouldn't hurt you to tell her that!" Have you forgotten?" he asked mom, "that this is our son we're talkingabout here!" Maybe," mom said, "then again, maybe not!" Just what does that mean? Maybe not?" Dad sounded...anxious?"It means," mom told him, "that just like Kathy, Brenda has found outshe likes being a girl, and might stay with us for a while!"Dad flopped in his chair as mom and I went out to the car. We picked upJenny who.
