Sex Story of the Week : "Brother Sister Sexual Encounter"

I have a twin sister who is my age. Since we were teenagers, I had thoughts about her in my masturbation fantasies sometimes. There were periods when she seemed to be in an awkward stage of development, but then there were other times when she was developing beautifully. By the time she was 18, she was almost irresistible. She was 5' 5" and 125 pounds with a perfect tan and beautiful blue eyes, not to mention a great ass.

I was too ashamed to tell her about my feelings so I was very subtle. I would do things like stare at her thong when she wore tight jeans, and I sometimes hugged her closely so that my erect penis would press slightly against her thighs. I have been told that I am also very attractive. I work out, but only to build defined muscle tone, so I have a slender and firm body.

I had a feeling that she had sexual thoughts about me because of the way she examined me when I had my shirt off or when she would glance down at my penis and male package when I was in my wet bathing suit. One night, our family got together for the holidays in December. When it was time for everyone to go home, the rain had turned to about a half inch of sleet and ice on the roads. There were seven people that had to stay over our house until the next day. My uncle and his wife slept in my bed, so I naturally moved over to my sister's room for the night.

At first, we started laying out pillows and blankets on the floor for me. When she took off her sweater, I could not help notice she was wearing a tight white midriff tank-top underneath. By this time, I was in just my boxers. I started to get an erection, and she noticed right away. I thought she was going to laugh but she didn't. She came closer to me and my penis got even stiffer. Our attraction to one another was undeniable at this point. We layed down together on her bed.

I gently pressed my penis up against her tight ass. I moved it in deeper between her legs so that the edge of my dick was pressing up against her clit. I pressed it I slowly, and I heard her moan. Then I heard her whisper, "More… More…"

I pushed my penis in deeper until I was ejaculating uncontrollably inside her. After I orgasmed, my penis went limp for a few minutes, but I stayed in the same position and it slowly got hard again. I continued humping her from behind. Now that I wasn't so horny, I could really enjoy the rhythmic sensation of our perfect bodies rubbing against each other. She eventually climaxed and thanked me. We have since both gotten married, but during family reunions, we always find time to evoke our passionate memories.
