Satori and I was a friend since we were young, and I often went to the house to play. We study at the same school, often sticking and deciding to date 3 months ago. During Satori's parents away, I was invited to his house to play. I didn't come to him for a while because I was often at school. Satori has a sister named Conan, I am her best friend, and we even take a shower together. Conan's outfit was extremely "cool" because she did not wear a bra, her nipple was visible through a thin layer, and her pink are constantly hidden in front of my eyes! He also noticed that I was staring at her breasts. While Satori was washing dishes, Konan-san took my hand and put it on her big breasts! Because I went to the toilet that night, my sister invited me to go to her room to play. She asked about me and Satori, asking if we had sex. When he realized that none of them had fuck each other, he asked me to continue the same thing. She took me to kiss her, let me squeeze my breast, let me undress, let me suck her dick and let me fuck her !!! And since then, Cone has loved me whenever I have a chance. I can't have sex with my girlfriend anymore because I always think about her.
