I stopped and felt shame. She then came near me and sit besides me and said “why did u stop stroking ur dick”. I was astonished hearing that and t...hen she put her hand on my zip and took my dick out of pants I was no more in my senses. Soon I what I saw that the sister or my teacher came near me and started sucking my dick. And my teacher started kissing on my lips. I too started kissing her all over.Then I undress my teacher and her sister (shelly) undressed me. Then I turned toward shelly to. .. I had never been so turned on before!She slowly..... so slowly.... lowered her pussy onto my cock, and I groaned as I felt her lips part and I entered her. "Hmmmmmmmm" she smiled. As I entered her fully she started to ride me, slowly at first. Her wet juices dripping down my long shaft onto my balls. Her pussy was a little tight but felt so amazing as she took me whole inside her. I held her butt with my hands lifting her slightly but letting her control the downward thrusts."Oh god yes!. ” he says.You comply quickly.“There that’s better.’ he states “now bend you knees slightly and then put your hands on you knees.’What is he up to you wonder. You hear him take several steps back and pull the leash tight making the collar tighten around your throat.‘Ok,’ he exclaims “now go ahead and pee for me so I can watch.”Well this is just humiliating you think to yourself. The desire to pee is too strong and it is no longer possible for you to argue with this man who has dominated you. I licked his balls and sucked on them one at a time. He loved it when I starred licking his shaft and then took it in my mouth.Even in the shower, I could taste myself on his cock. My bobbing head and tightly wrapped lips did the trick. Soon he groaned and his male taste filled my mouth. While he was still shooting, I stood up and turned around and offered myself to him again. He plunged his cock into my vagina and I felt the last few spasms squirt into me.When it was over - again he managed to.
