It was normal for the three of us to always be together. Sora (older sister) is the same age as me and my first love. She is reliable, caring, and overly serious. She is a slender beauty. Suzu (younger sister) is two years younger than me and has a cheerful personality. She is spoiled, lonely, and a little moody. She has big breasts and is plump. I had a vague idea that both of them liked me. Sora liked Suzu, and Suzu liked Sora... We hid our feelings for each other and went our separate ways when we went to college. I liked Sora, but I was afraid of hurting Suzu, and above all, I didn't have the courage to confess my feelings to her. Three years have passed since then. I went to Tokyo for a job... Due to my mother's meddling, I ended up staying in the room they shared... When I met them again, I was excited to see that they had become more mature. "You still like me, don't you?" "Hey, what are you talking about? When are you talking about?" "Well, give it to me, Suzu." "Eh...Ah..." It was Suzu who moved the hands of the clock that had stopped for a long time. Sora was jealous, but she stuck to me and seduced me, and then she kissed me, who was indecisive... and we just went with the flow and did it. Sora knew everything. "I've always liked you..." I heard her true feelings for the first time. "I've always liked you too..." We were devouring each other passionately. Even though I had just done it with my younger sister Suzu... I'm such a loser. When we realized that we had done it by atmosphere, the sisters began a fierce battle for me... "Hey, who will you go out with?" Sora was slender and had a great grip, and Suzu's chubby hug was too good to be true... I couldn't decide... There was no way I could say it. While I was struggling to answer, the three of us had sex together... It turned into a reverse threesome... If I could have such an amazing experience, I wanted to stay like this forever...
