Preventing herself from cumming became several times harder as she was brought to the point of orgasm again just by being near my cock. I had conditio...ed her well using positive and negative reinforcements until she worshipped me as her god. Pain was the negative reinforcement I used on her and the positive that she tried so desperately to earn was my approval. It was hard to believe that Natasha had once been a rich socialite before I got my hands on her. Now she was moaning like the biggest. “Get on your back on the floor!” demanded Lynne.Lynne removed that strap-on while I got on the floor. She moved down and straddled over my face. She put her asshole inches over my mouth. “Okay, baby, I want you to lick my asshole!” she ordered.“Yes master. I would love to lick your asshole,” I said, then stuck out my tongue.Lynne lowered her ass to my tongue. “Lick it!”I ran my tongue all around her sweet asshole. “Mmmm, feels good, my fuck toy,” she moaned.I continued to lick all around her. His handed rested on my back, gently trailing my body and finaly grabbed on. "You are my bitch," he said, surprisingly loud, I felt embarresed. It was then he started to fuck me. I mean fuck me. He was selfish, but not agressive, rough but not unpleasant. He fucked me like a cheap whore. I loved it.I let out a moan, he groaned, loudly again, as if on purpose, I wondered. Was he to proclaim that he had me here? Provoke?Master continued, changing rythm, depth and angle from time to time. He. It was a perfect butt, in my opinion, firm, yet I felt the flesh beneath my rough hard workers hands. I slide my fingers along the cleft between her butt and she arche her back indicating that my touch on her ass was desired. My mind flashed to thoughts of anal sex. I had never had the opportunity for it, I was scared to go forward, but she seemed to be begging for my touch. I parted her cheeks with my hand and probbed till I found the pucked opening. It was dry, I knew I needed some.
