English tutor Sawa Yuka secretly teases her own body during lessons with student Tachibana Mayu, careful not to be noticed. Mayu, while listening to explanations, struggles to contain her excitement, subtly touching herself between answers. During the lesson, the two gently rub their nipples and softly stroke each other's intimate areas. As their restraint nears its limit, they bring out a double-headed dildo. Inserting it between them, they whisper, "I've always wanted to be connected like this," and move their hips together as one, experiencing deep, shared pleasure.
