The two women are obsessed with spitting, passionately kissing each other while drenching each other's faces and bodies with saliva. They even spit on the man’s face and body, filling the surrounding area with the stench of spit. As time passes, the man’s presence gradually fades, and the two women become completely absorbed in each other. When they briefly regain awareness, they escalate things further by using their feet to torment each other's lower bodies or pressing their knees against intimate areas, deepening their erotic connection. Even as they occasionally stroke themselves, orgasm denial continues relentlessly, becoming unbearable. Constantly spitting, they enjoy the unfolding dynamic between the two women right before their eyes—dominant and submissive roles shifting unpredictably, leaving it unclear who is the top (tachi) and who is the bottom (neko). Note that some audio portions in the main feature are slightly muffled, but this is intentional and not a defect.
