She was supposed to be able to return to a peaceful life, but her former boss, who had a grudge against her, gathered together his fellow Chikan friends and took revenge. Surrounded by a blind spot in the car, her mouth was sealed with an erect penis, and she was raped in a silent gang. Furthermore, she is showered with a large amount of semen and her whole body and face become muddy!
