DVAJ-573 I've interrupted my sister's self-concertation several times.

I mean, it's not like my sister's room's sound is a hysteric sound... and it's not like it's masturbating, it's a real thing, it's always a shame to see my sister do something so humiliating, and it's like she's in her room, and it's like it's clear that when she hears a hysteria, it just doesn't seem like she's going to come in and stop masturbating, but it doesn't mean that she's going to want to be upset, and then a couple of days later, it's a tragedy, even if she's thinking about it now.
