About a month had gone by when I finally got up the nerve to tell my mom about what had happened. She was of course mad, but in the end, she thanked me and didn't care about my dad because he was lusting after some girl from work. During the day, we seemed like a normal mother and son. I would help her out with groceries and such and she would scold me when I did something bad and so on, but when we were alone at night, our relationship was quite different.
The things she said when we were having sex were incredible. She'd shout things like, "YES! FUCK ME LIKE THE WHORE I AM!" Then, there was the time she told me to fuck her until she couldn't see straight. After a big meal of oysters, I obliged and, after a lot of work, succeeded. But as I said before, my mom felt that we should have another female in our relationship. We both set out to find someone that we thought would satisfy us both. Looking back on it now, I should have realized my mom's plan, but being naive as I was, I didn't realize.
You see, she had been planning since the day after our first session of sex of a way to involve my sister. She would get her chance three days after I told her about how I seduced her. My sister had come home for spring break and was planning on going to the Bahamas or some place like that, but my mom played up my insomnia thing and added dad being thrown in jail for 25 years and my sister happily decided to stay at home. I didn't know this because I was out searching for some blonde, big breasted female that just wanted to have sex.
I came home and my mom immediately offered me a glass of tea. I accepted not knowing how much caffeine was in it. My mom wanted to play out this insomnia thing by making me stay up all night because, after my sex with mom, I didn't have sleeping problems. Needless to say, I was up all night and my sister was convinced that she would help me. I left early the next day to continue my search at coffee bars and places like that. While I was gone, my mom continued her plan to get my sister to have sex with not only her brother, but her mother as well.
Maybe I should back up a bit to speak of my sister's past. You see, my sister is about as hot as my mom. She's 5'1 with a perfect, curvy body and nice 36c breasts. This made it impossible for her to love sex. It also made her impossible to stick to only men. She had been having sex with women about as much as she'd been having it with men. She often told me this because she needed someone to confide in. I was happy to hear of the stories and used to jerk off upon hearing them.
My mom was this way when she was in college as well, and hence had no problem with having lesbian sex. The only problem she faced was convincing my sister to have sex with her. She began working her magic by dressing very sexy around the house, and got my attention quite a bit, and since my mother and I both agreed to no sex during the time my sister was here, I was forced to jerk off again.
My sister also noticed, however and it showed when she wore white shorts to breakfast one morning when my mom was wearing nothing but a bathrobe which was open. Because I was hardly ever at the house anymore, I had no clue what was going on at home because I was searching for something that wasn't there and having little success as you can imagine. My mother, on the other hand, was progressing very well and knew it. Without my knowledge at the time, she and my sister had agreed to take a trip to the beach.
