The girl is left in the care of her uncle's family for a week—a household ruled by twisted rules and abnormal routines. During her stay, she is forced to witness her cousin's father engaging in incestuous sex with her, compelled to perform lesbian acts with the cousin, and made to bathe with the uncle. Desperately trying to adapt, she struggles internally with fear and confusion. One night, when the cousin and aunt are absent, the uncle chokes her and violently creampie fucks her. That night, she begins to feel pleasure against her will. From the next morning on, the uncle's training intensifies, and she gradually becomes addicted to the acts. Soon, she finds herself saying, "I don't want to go home yet," and "Cum inside me more," descending into a cock-crazed state. With each encounter, her mind becomes increasingly twisted.
