I got accepted into college! But even after moving to Tokyo, I still had to take classes remotely... Because of this, I couldn't make my college debut and my stress and sexual desires were piling up. Then my stepsister came to visit me at my apartment. But because of the situation in the world, I couldn't go out and have fun, so I was alone with my stepsister in a small room. So, with nothing to do, we just had sex day and night! We had sex without going out at all! Having sex so much that I lost track of the date wasn't so bad.
