While Rika Tsubaki is relaxing at home with her boyfriend, a gang of thugs suddenly storms in. After discovering that her boyfriend stole money, they threaten him with a choice: suffer a group beating or hand over his girlfriend for sex. He sacrifices her, and she is mercilessly raped before his eyes, abducted to a filthy abandoned building, and gang-raped. Her face and body are drenched in semen, and repeated creampies reduce her to the gang's public toilet. Produced and copyrighted by K.M. Produce Co., Ltd.
