One day, I was outed as a virgin at school and mocked mercilessly. I returned home feeling down. Then my cute little sister came over and threw out a terrifying line. "Hey hey, are you a virgin, big brother?" Not only my friends but even my beloved little sister made fun of me!! Shocked, I thought about jerking off and going to sleep. But the next moment, my sister uttered another unbelievable statement. "...Should I help you graduate from being a virgin?" From that day on, I ended up having days where I was completely at my sister's mercy…
