“Blackmailing Bitch Sister”
It all started when I was 18 and my sister was 16. We were in the same grade in high school and both of us were doing great in our classes and had a lot of friends.
But my sister and I had a dark secret. We both had a thing for each other. We would sneak into each other’s rooms at night and make out. We would whisper naughty things to each other and get each other so excited. It was the most thrilling thing either of us had ever experienced.
One night, my sister suggested that we take it to the next level. I was hesitant at first, but eventually, I agreed. We both went down to the basement and started making out. It was intense and so much fun. We started taking our clothes off and soon enough, we were both completely naked.
My sister then suggested that she should be in charge. She said that she would dominate me and that if I didn’t do as she said, she would blackmail me. I was scared but also so excited. I knew that this was something that I wanted to try.
My sister then started taking control. She tied my wrists to the bed and then started exploring my body. She kissed all over my body, tugging and pulling at my nipples, and then she started to slowly make her way down my body. She licked and sucked my cock until I was rock hard, and then she started to finger me and put her tongue inside me.
It was so good and I was in complete ecstasy. I was scared that she would tell everyone about this and that I would get in trouble. But I was also so aroused and I wanted her to keep going. I begged her to stop but she refused, and instead she started to suck my cock again and then mount me.
At this point, I was so close to cumming, but I was also scared of what she would do next. She was in complete control now, and I gave her my full submission. She then started to ride me fast and hard, and I soon felt myself orgasming deep inside her.
After we were done, my sister untied me and then said that she was going to keep this as her secret. She said that if I ever told anyone, she would tell everyone about our night together. I was scared, but I also trusted her and knew that she wouldn’t do it.
However, over the next few months, my sister started to get increasingly demanding. She would threaten to tell everyone about our night together if I didn’t do what she wanted. She started to blackmail me for money, and then for sexual favors.
At first, I was scared and didn’t want to do it, but after some time, I started to enjoy it. I liked being under her control and I liked being able to please her. We started to explore all kinds of fantasies and I started to become a real slut for her. I was her obedient, blackmailing bitch sister and I loved it.
We would play out our fantasies in my bedroom and in the basement, and I would do anything she wanted. I was her willing sex slave and I loved it. We would role-play different scenarios and I would be a slut, a hooker, and even an escort. I loved to be her naughty little slut.
Eventually, my sister stopped threatening me and we just enjoyed our relationship. We were still in the same grade in high school but no one else knew about our secret. We continued to explore our fantasies and I became more and more submissive to her. We still have our secret relationship to this day and I love it.
I think about our time together often and I still feel aroused when I think about it. My sister and I have a special bond that I wouldn’t trade for anything. I’m so glad she blackmailed me, because if she hadn’t, I would have never found out what an amazing experience it can be.
