In a forbidden underground space rumored to have produced over thirty victims, "Shiokawa Untan" steps foot inside. Her M-switch is so obvious that she decides to flip it by giving her spankings, strangulation, and bondage using iron restraints after turning her on with these acts. Secured in humiliating positions, her exposed anal opening quivers with excitement. Despite her resistance, her mawkish hole is forcefully stretched open to accommodate various objects such as dildos and enemas. #SilverFox
