To push Rena Miyashita's sensitivity to the limit, MOODYZ orders her to abstain for a full month—no daily masturbation and a chastity belt to enforce it. Constant denial turns her frustration into a feral hunger for men. When the restraint finally ends, she skips the shower, immediately sucks and takes cock, and fucks until she nearly loses consciousness. The unscripted rampage grows from four people to six and then eight as she devours every cock around her and follows pure instinct to the end.
