DXEB-001 ENDRESS BLACKHOLE vol.1 ~The Endless Black Hole~ Humiliation: Yamamoto Mariko, Kanae Ruka, Uehara Karen

Eight women are restrained on a bondage rack, completely immobilized. A relentless wave of continuous anal sex ensues. Using a special device, their clitorises are directly stimulated with electric shocks, inducing forbidden orgasms. Even if they try to resist or escape, the switch is locked in place—there's no way out. Overwhelmed by intense pulsations, they're driven to the brink of madness, tormented until not a single trace of dignity remains. This is the definitive version of cruel, prolonged anal torture, where each woman's twisted humiliation is savored in detail.
