Des:A man and a woman who seem to be friends. A man is a trainer and a woman invites him to his girlfriends home to teach him how to stretch. Apparently, they had sex once while drunk, and their friendship has already fallen apart. It is natural for such two people to become horny if their bodies touch each other behind closed doors. In no time at all, his hand reaches his crotch, and he can relieve his lack of exercise with sex.
