I and Satori have been friends since childhood, I often visit his house to play. We both study at the same school, are always together, and three months ago, we decided to date. When Satori's parents were away, I was invited to her house to play. Since I often stay at school, it's been a while since I visited her house. Satori has an older sister named Konan, I used to be close with her too, we even took baths together. Konan dresses very provocatively, not wearing a bra so her nipples are clearly visible through her thin clothes, her pink nipples constantly visible in front of me! She also caught me peeking at her breasts. While Satori was doing the dishes, Konan took my hand and placed it on her huge breasts! That night, when I went to the bathroom, Konan called me into her room to play. She asked about me and Satori, asked if we had sex. When she found out we hadn't, she seduced me to continue what we were doing earlier. She kissed me, let me squeeze her breasts, undressed me, gave me a blowjob, and let me have sex with her!!! And since then, Konan has seduced me whenever she had the chance. I couldn't have sex with my girlfriend anymore because I kept thinking about Konan. Once I went to play when my girlfriend hadn't returned yet. I went into Konan's room, had sex with her. I suddenly saw a small ring on the table. And then I remembered a childhood memory, and I knew why she wanted to have sex with me like that. This ring was the one I gave Konan, even though she no longer wore it, she always kept it, cherished it, and kept her promise to be my wife. Yet I forgot, went on a date with her younger sister. I don't know what to do, but one thing is for sure, I will not leave her, I want to be by her side caring for her, loving her, and making it up to her!!!
