Miyumi Ayu has become completely obsessed with anal pleasure. A natural-born masochist, she says, "Vaginal sex, vacuum blowjob, and titty fuck are great, but I really want it in my ass." When both her pussy and ass are filled at the same time, her intensely passionate moans captivate everyone watching. Her innate submissive nature stems from a deep dependency on anal stimulation and an insatiable passion for pleasure. In the end, fulfilling her own desire, she experiences anal creampie—depicting her ultimate pleasure.
