I sat transfixed at this erotic scene. These young fit men, who clearly knew what they were doing teased and played with my beautiful wife. She was clearly enjoying the attention. Her master was directing proceedings. The teasing, spanking, pinching and tickling continued until her master decided to take over. He had some narrow rope in his hands and proceeded to tie these ropes around her breasts and under her crotch. Her breasts looked engorged and her groin looked to be protesting under the pressure. The young men were instructed to release her hands, but leave her feet tied where they were. Her master told her, " kneel bitch!". Which she did with a "yes master". He then brought a small bench for her to rest her arms on. He knelt beside her, stroked her all over gently and began to snog her right in front of me. She eagerly kissed him back. He then tied her hands together in front of her. And then to the bench. So there she was knelt helpless looking right at me. There was no fear. She trusted him completely. He sat on the bench in front of her and said, "suck my cock slut!". I couldn't see this, but from the gagging I knew she was loving it. By now my cock is rock hard. He turned to me and said that I had a punny cock and he was going to give my wife everything she had craved for. He said I was useless and needed a lesson. I just sat in silence. For the next hour or so he teased, pinched, slapped and fucked her tied where she was. It was so erotic I had cum all over my leg. Once finished he said to her, you are a nasty slut and you are to take the two boys to the bed in this room and fuck them both. She said with a grin on her face, "yes Master". The two young black men untied her, led her to the bed and stripped her naked. She was obviously enjoying this and joined in eagerly. Her master just sat and watched. She was fucked by these men every way possible. She took their manhood without complaint both vaginally and anally. Her moans and begging to be fucked were both loud and dirty. Once the young men had had their fill, they had me released. They gave her a dressing gown. Once this was on, she went to her master and kissed him passionately. Not me, him. We left and there was no conversation on our way home. I could smell the sex on her. I was both aroused and jealous. But knew not to say anything. She was now truly a slut wife, and I was a cuck.
