It plowed into my ass as teens deeply as it could until I felt its balls bounce off my taint. The faint pain from my sphincter was quickly overwhelmed by the fullness that cock gave my insides. It barely had a moment to nestle into my juicy contours before he pulled it out and then rammed it back into me. I let out a cry of intense pleasure as this dog began fucking me relentlessly. His backside arced, dipped, and plowed in a shockingly fast rhythmic motion. My ass was never empty for more than fractions of a second as he plunged every millimeter of his meat into me again and again. Blood was rushing to my own cock as it flapped back and forth from the force, but it barely had time to harden before the fun started. With every new thrust I could feel this dog’s cock getting thicker. Each push became a little tougher for my sphincter, and more filling for my insides, as his knot began to rapidly inflate. My cries were echoing off the walls now and as that bulge ceaselessly grew I did the only thing I could. I clenched. My sphincter sucked the cock and knot right into me, pressing that fat bulge against the walls of my rectum. The dog kept right on fucking me, even though he could no longer extract his cock from my ass. The knot ballooned to twice the size in seconds and I screamed with pleasure as I became fuller than I’d ever been before. I felt a sudden warmth in my belly as I felt that cock begin violently pulsating, spewing his cum deep into my ass. He came into me for almost 30 seconds as his rhythm slowly dropped. As he slowed to a halt on my back I suddenly became aware of my own violent shaking within the iron harness. Then there was a tug. It was light, but firm, against my sphincter. Terrified to petite let that thick knot pop out of me, I squeezed shut as firmly as I could. But the dog skinny persisted. And not only did he persist, but he seemed confident that he would win. He slipped off of my back and I blowjob felt him turn, twisting his cock as he came to be ass to ass to me. With this newfound leverage he gave a stronger thrust that I almost failed to hold. Then he gave one final push and I felt nine inches of engorged knot and cock rip right past my sphincter and out of my body. I squealed at the stinging teen pain, but it subsided quickly as my intestines rearranged themselves. The handler, hardly pausing at all, quickly reemerged in my field of view in front of me with the dog at his side. I could see the cock that had violated me swinging between his legs as the handler left the room with him. He put his hand on her left knee before he even started speaking, and left it there. Then like them he too seemed to have been erased from existence. Tegan wasted no time taking his sticky cock in her hand and mouth, her uncovered eye gazing up at him as she licked him skinny clean, moaning as Brandon continued to ravage her behind. She squeezed her knees up and together against him. It wasn't anything particularly exciting; but just the fact that I got to stay out past midnight—with Annabelle—made it extraordinary. She’d just end up boring him later if she used her best blowjob techniques so early. Oh yes she did great, and so did you she said teen with a wink. “I can't go to your place and study with you,” I told Nathan after classes were over. The boys sat on either side and caressed me gently; in direct contrast to the hard pounding they had just been giving me. I could see that they were both still hard and realized that neither of them had cum. When we came into the hotel, we walked by the bar and I stopped dead in my track. “Stick the fingers you were fucking her with in her mouth. Whether it was happy or sad, I couldn’t say. However, he wasn't very good, and to this day no man had given her an orgasm. Karen and Emma took theirs but didn’t put them on. “Oh yes sweety.” Arthur said watching the smooth sway of those pert buttocks. I had put more power into teens it, though I knew it petite wasn't enough to destroy him, it would be the start. Just… just dropped something on my foot.” She managed to get a reassuring smile out. A few months ago I went to a party at Rob’s house. I want to scream just like the first time it happened, but the audible “Shhhh” kept me from doing anything. She had black hair, like me, only hers fell sleek and silkily down her back. “I am not sure,” the physician replied desperately playing for time.
