Aya Shiomi stars in this adult vinyl video from Vinyl Bookstore. Playing the role of "Ai," a masochistic woman, she becomes a sex slave to her younger brother, a shut-in who has been confined at home as a self-appointed security guard. She suffers unexpected and brutal assaults, including intense edging, having her face stepped on while her pussy gets wet, being choked during missionary-position sex as her cervix is pounded, and indulging in deep tongue kissing with saliva dripping from her mouth. In the climax, she receives multiple creampie loads from her insatiable younger brother in this extreme and intense incest-themed production.
