I felt her boobs pressing against my chest. An arousing odour of sex was emanating from her. I gave Mum kisses, letting my tongue explore hers and sha...ing our saliva. My cock, which was still semi rigid, began to stir. Still kissing, Mum reached down and began to squeeze it. Feeling the hardness of it and in no time I had a full, stiff erection. "God you young studs sure recover quickly. Baby what would you like me to do with it?" Let me put it in your mouth and you can gently suck on it."I. He took the cuffs from my handbag and cuffed my wrists in front of me. Then he locked the steel collar around my neck, now unremovable as there were only keys for the cuffs in my handbag but none for the collar. With a tow rope he tied my cuffed wrists to the bed in such a way that I was placed on my stomach and the knot of the rope out of my reach. I was completely helpless and offering my ass. The guy took pictures, then sat on my arms with his cock dangling directly in front of my mouth.. Just like if you were giving a girl a french kiss."She laid on her back, with trepidation I moved my head between her legs. She was whispering to me now telling me where to concentrate my efforts and when to switch motions. "Now use your fingers at the same time," she said. She was moaning quietly and beginning to writhe more rapidly. After awhile I told her my tongue was getting tired, she told me not to stop, I was almost there. At the time I remember not knowing exactly what she meant by. He moved his dick in and out of my mouth. I was sucking it hard. Tears were rolling down my eyes. He was moaning as well as abusing me which made it more erotic.“You dirty slut. Suck it all. A bitch like you deserves to be my hoe.”I was tired and choking. He pulled me up. Holding my shoulder, he turned me and bent me on the edge of the bed. He was standing behind me. He pulled down my pants which were completely wet by now. He spanked my butt hard. ”Ouch!”He removed my panties and threw them on.
