The other day me and my FWB were talking about what we each liked. The topic of some pet play came up and we tried it. He put a collar on me with a chain leash. He pulled me from the floor to his dick and made me start sucking him. He didn’t let me stop sucking him until he came. He said he had other plans for me. He laid down on the bed and pulled me on top. He Straddled me over his knee. He told me to be a good girl and use his knee to get off. I was so embarrassed and so turned on as I humped his leg. He kept pulling on the leash choking me and calling me a good girl. I was so desperate by the end begging for permission to cum.
