Hina and her boyfriend live together, scraping by on part-time jobs while saving little by little for marriage. One day he steals a dropped pay envelope, only to discover that its owners are vicious thugs. Though he escapes, they trace his address through the wallet he dropped and storm into their home. He begs to repay the money and pleads with them not to touch Hina, but they decide she must share the punishment. Forced to watch, he sees one man after another rape and creampie his beloved girlfriend. Covered in semen, drooling and convulsing through repeated unwanted orgasms, Hina is overwhelmed by the abuse until she can no longer resist, while the men mock her boyfriend for never satisfying her.
