A man and a woman who seem to have a friendship. It seems that a man is a trainer and a woman is invited to her home to teach stretching. Apparently, I had sex with drunken momentum once and my friendship has already collapsed. It is natural for such two people to get horny if they touch each other in a closed room. In a blink of an eye, your hands reach out to your crotch, and you can get rid of your lack of exercise with sex. –
