Naoya thought Aya was his girlfriend and kept lending the concept-café worker money when she claimed her mother was sick, she could not pay her tuition, or she was too sensitive for demanding work. She never paid him back, and whenever he asked for sex, she said their relationship was too important and offered only handjobs. Then he overhears her admitting that she merely uses his home for convenience, cheats with other men, and only hates having sex with him. Naoya recruits a friend and takes revenge with a powerful aphrodisiac, toys, a thick cock forced into her mouth, and relentless sex. Aya apologizes and cries that too many orgasms are making her lose her mind, but the punishment continues until she is screaming, squirting, convulsing, and rolling her eyes in pleasure.
