MOODYZ orders Rena Miyashita to abstain for an entire month to push her sensitivity to the limit. Even her daily masturbation is banned, and a chastity belt keeps her from getting any relief. Constant denial sends her frustration through the roof until the mere sight of a man awakens a feral hunger in her. Once released, she skips the shower, immediately sucks cock and starts fucking, refusing to stop until her mind goes blank. The unscripted group sex grows from a four-way to a six-way and finally an eight-way as she devours every cock around her and gives herself completely to instinct.
