Close-up, closed-room sex that took place in a space for two called a private massage after personal training! A personal space of one man and one woman, one-on-one, one-on-one... and erotic closeness! Under the guise of a massage to relieve muscle fatigue, an extreme dick erupts! The reactions of the female members to the crotch of the male trainer who keeps hitting on them are varied... various things such as disliking it, being curious, and feeling it all the way (laughs) This is a short-time sex video of female members who even took their sexual desire training to the extreme during training!
