I've had sex, but I've only had a handful of times, and I masturbate, but what is cum? I don't really understand it with that kind of feeling, my sister came to me for a serious consultation. I can't understand this thing even if I teach it in words, so I have no choice but to actually try it. That's why the older brother puts up his body, especially his cock, and confronts her sister with all his might!
