A candid at-home documentary about the sex people reveal only to trusted partners, following three adult couples and their distinctive desires. Kaho, 21, is charming, impulsive, intensely horny, and open to almost anything. Yun, 21, is a beautiful, reserved masochist whose quiet exterior hides a powerful sex drive. Yuna, 21, looks soft and sweet but pursues sex like a predator, mixing embarrassment with raw desire. Their everyday private lives give way to intimate sex, squirting, facials, domination, cosplay, choking, and uninhibited couple footage.
