Known as a representative work of Tadao Yoyogi, this film features two couples—Mariko Itsuki and Takashi Kato, and Youko Kanou with Tatsuro Hibino—engaging in realistic, intimate sex that feels deeply personal. In the first part, Youko and Tatsuro take center stage with intense foreplay. Pressing their bodies close, they progress into passionate, prolonged kissing. Focused solely on mutual pleasure without seeking or giving dominance, they move as one unified being. Through this extreme intimacy, Youko ultimately experiences her first-ever fainting episode with Tatsuro. In the next segment, Mariko and Takashi appear, beginning with long, deep French kissing, then using intense physical connection to re-examine the nature of love and sex. Celebrated for its profound emotional depth and powerful physical expression, this film stands as one of Tadao Yoyogi's acclaimed masterpieces.
