Every couple has a different form of love and a different set of kinks. This homemade documentary shows the everyday intimacy and sex these women reveal only to their boyfriends. MAIRI, 29, is a spirited childcare worker whose tough personality disappears when her highly sensitive body takes over. HINAKO, 24, is a gorgeous jewelry-store employee with huge breasts who throws herself into sex at full intensity. MANA, 25, works in beauty and behaves less like a girlfriend than her lover's kinky pet, her massive breasts and dominant appetite driving the action. SARA, 25, is a gentle medical administrator with K-cup breasts who openly indulges her masochistic side. In the privacy of their homes, all four couples expose their unfiltered habits through wild sex, masturbation, cosplay, squirting, big cocks, and facial cum shots.
