Suzu, a beautiful girl, is kept as an anal-only pet by a perverted older man. With a deeply masochistic personality, she finds living with him to be the perfect environment. She experiences climax through forced anal masturbation, endures enema torture, and gushes massive amounts of semen daily. She also discovers new pleasures through double-penetration toys and double penetration sex. This work reveals Suzu's life as an anal pet in full detail.
