My little sister is incredibly cute, even to me, her brother. Honestly, if she got a boyfriend, I’d go crazy. I thought it was just sibling love, but I was wrong—I’m in love with her. Since realizing this, I couldn’t even look her in the eye. If she knew I saw her as a sexual object, it’d be over for me. But when our parents left for two days, we were alone. I couldn’t hold back anymore! My sister sensed my strange behavior, but when I made a move, she didn’t resist—she even seemed happy! From then on, it was a whirlwind of sex. We couldn’t stop, even if we felt guilty toward our parents.
