.I wasn't about to make it a three party event..not after witnessing those two large cocks working Susan over...she had to be stretched beyond anythin... she had ever known, and I had exactly what I wanted....The next morning we awoke, and she had a bit of a hangover and mumbled something about being kinda sore 'down there' but she didn't pursue it, and I didn't either. We had another day or two and I enjoyed them thoroughly....I don't think we went back for more dancing...I think she had had. Finally, as Tonia felt herself growing very horny and more than ready to do something very naughty with her student, she let her hand that had been casually resting on Marcus's shoulder slide around and she began caressing his muscular chest. That more than caught her hot young student's attention, and he turned to look Tonia in the eyes to see what it was that she had in mind with him."I know you didn't expect this but there's something else I want from you, Marcus, before you go home tonight.. I mostly like to watch the people watch the a****ls, I guess. Suddenly I turn down a path I have never been down before. Out of curiousity, I keep taking the winding path. It is the prettiest part of the zoo I have ever seen. I begin to feel light headed and sit to rest. I guess I fall asleep because when I awaken I am inside a glass box in some sort of laboratory. I am naked and my pussy is shaven. A voice says, "Oh good! You have finally woken up!". I don't see anyone. Just a white,. The dog in her cunt, feeling he was now knotted and sealing the bitch began his frenzied short thrusts and Diana felt his cum painting her cuntal walls. Grabbing the dog in her mouths testicles, she gently squeezed as she continued to suck, attempting to make sure she had emptied him of all his fertile seed. The dogs succesfully mated with her and indeed she did service all males including the hulking alpha. She bore litter upon litter of pups, all in all 25 young ones and they all feasted on.
