This role-play is performed by adults. Passed the university! However, even if I moved to Tokyo, I would still have remote classes... Thanks to that, I couldn't make my university debut and my stress and sexual desire were building up. My sister-in-law came to visit my apartment. However, because the world is in such a state, I can't go out and play, so I am alone in a small room with my sister-in-law. So, as a result, we have sex all day and night with nothing to do! Have sex without going out at all! Days where you just have sex until you lose track of the date are surprisingly not bad.
