For several years I have had a sexual relationship with Tanya mostly only one or two times a month for a night or two. within the first few months I knew she had some strange sexual desires just by the ways she would satisfy me with many varieties of sex toys. I never objected to any of it simply because she always had a knack for keeping me aroused and would have me orgasm so many times I couldn't count them. It was obvious she got enjoyment controlling me and pleasured herself by having me climax over and over. I began letting her spank me and take photos of us especially when using a strap on dildo on each other which is her favorite. She also is bi-sexual but hasn't had a boyfriend for a long time. My boyfriend knows nothing about Tanya and I doubt he would ever except my relationship with her. Well over two years ago Tanya had Luke move into her house. Tanya was 40 at the time and Luke was only 19 and sort of a quite type guy who she has known for many years and the son of a co-worked who moved to Florida leaving her son here. The first 3 or 4 times I visited Tanya and we had sex together Luke always stayed in his room and I rarely saw him. It never occurred to me that Tanya was abusing him sexually until she openly admitted it one night bragging about how she had him under her control. She at first only told me about things she did to him and said he was not only submissive to her but that he was also intimadated and afraid of her. A few weeks later when I went to her house she called Luke into her kitchen where we were having a drink. As Tanya and I sat there she turned to him and told him to take his clothes off telling him she wanted him naked. He looked at me and I could tell he was not only dumbfounded but couldn't believe Tanya was doing this in front of me. Tanya looked at him again and screamed "now" and Luke didn't cry but I could see his eyes tearing up as he began taking off his shirt and pants. It took a few minutes but there he stood naked in front of us as Tanya began saying how small his penis is and it is. Tanya got up and took his penis in her hand and then ordered Luke to masturbate in front of me. It took him quite awhile to get an erection and even then his penis is less than five inches which Tanya again mentioned how small it was. After he ejaculated she made him clean it off the floor on his hands and knees then told him to go to his room. Then Tanya and I went to her room where we had sex for hours and it seemed Tanya was more excited than usual. She kept talking about how she could control Luke saying she would show me more the next visit.

It was the next month until I was able to go back for the weekend and two days I'll never forget. During that weekend Tanya turned me into the same sadist she had become since Luke lived with her. I was apprehensive when she had the three of us go down into her basement and immediately ordered Luke to undress. Once naked she tied his hands to a rope hanging from the rafters and began spanking him with leather strap then used a long thin wooden paddle. He wimpered and cried most of the time and when she was finally done spanking him his butt cheeks were crimson red. She used a lotion and wiped his cheeks with it then squirted some on his penis and scrotum and played with his genitals until he got an erection. As much as I felt sorry for Luke at the same time it was unreal how he did whatever he was told. After she untied his hands she made him bend over the table that was there and she began taking off her clothes and put the strap on dildo around her. She held his butt cheeks apart and put KY jelly on his anus and before penetrating him anally ordered him to jerk off. He obeyed her and she basically had anal intercouse with him using the strap on dildo. I could hear him moan at times and eventually saw him ejaculate as Tanya kept going in and out of him. I couldn't believe what I was watching but shamefully it became arousing to me. She then ordered Luke to lay down on the table and the next thing I knew Tanya got on the table and straddled Luke's face with her vagina and made him give her oral sex asking me if I wanted to try it next, which I wasn't ready for. By that time Luke's penis was limp and very small probably only a little over an inch long. Tanya in the mean time was having orgasms as Luke was licking her and I felt myself getting turned on by it all. Tanya finally got off the table and put a robe on and told Luke to go get a shower. We had dinner and the entire time Luke just sat there and the only one talking was Tanya. When finished eating she made Luke undress and made him do all the cleanup and dishes as she and I had a drink.

At 8 pm that night we again went to the basement where this time I found the courage to get undressed after being informed Luke would see me naked later. It was only Tanya and I and I did let her spank me but not nearly to the extent she had spanked Luke earlier that day. Tanya then pampered me for almost an hour laying on that table having me so aroused at times I wanted to scream and yell. It was a little after 9 when she summoned Luke who came down to us already naked. It was slightly embarrassing being naked in front of Luke but withing minutes I was perfectly comfortable. Tanya took Luke to the ropes again and tied his hands over his head but this time handed me the paddle telling me to spank him hard. His butt cheeks were still red and at first I only slapped his butt softly and suddenly realized I enjoyed doing it and aroused by it. From then on Tanya called all we did and found myself using sex toys on Luke anally for more than an hour and I also masturbated him as I penetrated him with a vibrator. Later he performed oral sex on me and Tanya and then Tanya again spanked him. The next day was almost a repeat except that I became more aggressive with Luke like Tanya already was. I used the strap on dildo on him and know now why Tanya enjoyed doing it to him. Since that weekend I try to get there at least twice a month for a weekend or just a day sometimes. Luke has became like a slave to both of us and puts up with whatever we desire. I am just as bad as Tanya anymore even when I spank Luke and particularly when I use the strap on dildo. Tanya and I also satisfy each other but what we do with Luke is only a bonus for me. My boyfriend would have a fit if he ever found out about this.
