477GRMO-079 Observing humans, stretching where skin touches skin turns into foreplay, and before you know it, they're fucking friends with benefits

Film Introduction

A man and a woman who seem to be friends. A man is a trainer, and a woman invites her to her house and teaches her how to stretch. Apparently she has had sex with drunk momentum once and the friendship has already broken down. It is natural for two people to get horny if their bodies touch each other in a closed room. In a blink of an eye, my hand reaches my crotch, and the lack of exercise is resolved with SEX.
