On her way home from a circle drinking party, Shoko Otani is invited to the house of a kind and gentle man, where she gradually becomes aware of emotions she can no longer suppress. Hidden deep within her heart, a dominant, lustful side begins to awaken. Feeling intense possessiveness toward the man who once desired other women, she refuses to allow him any contact with other women, forcing him to repeatedly confess "I love you." Once she has claimed him, she won't let him go, filling her with creampie after creampie, greedily extracting his semen. While he sleeps, she binds him tightly with ropes and handcuffs, tormenting his nipples and making him ejaculate again and again. Driven by primal instinct, she rides him relentlessly, her hips grinding as she takes his sperm for herself.
