Tanno Yui plays a young girl in this tale of adolescent conflict and pleasure. Her rapidly developing body is humiliated as it is played with by her stepfather, the object of her loathing. Despite her words of refusal - "gross" and "stop" - her body cannot resist his skilled caresses, and she is overcome with a pleasure so intense it raises goosebumps. Why does being touched by a man she hates make her so wet? Trembling with self-loathing, she swallows her stepfather's penis and allows him to cum inside her. The young girl's virginity is defiled by her stepfather's semen, and a cruel awakening of her sensitivity.
