Minutes later, Daddy arrived, opening the door without knocking. Sir kept me on his cock, so I was unable to see the doorway behind me, but I was acut...ly aware of being watched while I was used as a bondage slut. The humiliation I was starting to feel was almost as potent as the feeling of helplessness in the cuffs and collar. "She is a cute little slut, especially in that outfit. And those bindings. You found a good one, my friend." Daddy casually said over my shoulder as I heard his zipper. Getting him nice and clean and ready to go again! I angled my head to take as much of his massive cock into my mouth as I could. And then I started bobbing my head up and down, knowing that Jason would love the warm moist feeling of my mouth.Part of me wanted to blow him to completion and allow him to pump his potent load into my stomach. But my need to feel him back inside me was too great, and so I lifted my head off his wonderful cock and stood at the side of the bed. I took a moment to step. It was soon being stroked to full hardness and then the stroking stopped. A new sensation took over as my cock was now licked and sucked on. I could only take a few minutes before I knew I would soon cum so I withdrew my cock and sat down. Again his cock appeared and this time I reciprocated by sucking on his knob. This time he started to thrust and without warning he started to cum and I was able to pull away so his shots of spunk went over the booth floor. I was going to put my cock back. She started moaning again...I began to pick up the pace slamming all my meat in the deep...my balls slapping her swollen wet clit...over and over..deeper and faster..she moaned and moaned..louder and louder..Billy and Natalie continued to make out and watch us fuck...by now we had been fucking for 40 min or so..I could feel her pussy gripping my shaft as she got louder and louder...I grabbed her hair and pulled her deep int me..WOW soo fuckin hot..I noticed goose bumps on her ass and she came.
