The knot is pure pleasure, maybe a little pain at first pushing in, but then, pleasure. She pushed as he pushed. She wiggled her butt as she had learn...ed from the multitude of penetrations to help wiggle the knot into her hole. She sighed and gasped loudly as the knot pushed in finally. They both stopped and readjusted themselves and then Sam started in again. Harder and faster. The knot now sliding inside her. The head of his cock suddenly deeper inside her with the knot. As she felt Sam tense. The banging was intense. Well it was close to thumping. I slid the security bolt back and released the deadlock. My face was suddenly full of a piece of paper thrust directly at it with some swift garbled obviously rehearsed script sounding like a bailiff’s court order, ‘default payments’ and ‘repossession’ and then the door frame was occupied by three big guys. I mean big guys. Like all over six feet. Well at a petite five two, I was really looking up without heels. As a slim pixie featured. Not the basic Humane Society variety of animal lover, not the devoted owner variety of animal lover, Fonda was truly an animal lover!We had talked several times about her "adventures" and fantasies, each time getting to know one-another better. Several weeks ago, Fonda admitted to me that she'd been "experimenting" with her dog Lucious, a big Black Labrador Retriever. A very male, big Black Lab.I learned that she and Lucious had been sharing in some sexual play- times, and that Fonda had even. I guess I was just one horny submissive cunt. By the end of the day though, I was getting a little sore. My cunt had been pounded for hours and I noticed I was not lubricating as much as when I first started.Finally, the day ended and Mistress Pam said, "Very good cunt. You sucked 11 boys and fucked 1 dog along with 22 boys and you were cumming so hard almost all of the time it was happening. Only a whore would do that. I am proud of you, now you have to make us girls happy. So just stay on.
