Delivery Girl Reiko Anal Training [KochiKame] (Kichiku Koubou)

A police officer is abducted and taken to a remote mountain warehouse known as the "Devil Workshop," where a sadistic captor films his escalating torture. Subjected to extreme physical and psychological torment, drug injections, and forced degradation, the victim's panic mounts as promises of release prove false and threats of exposure loom. The captor's cruel hobby is part of a wider series, promoting other works where characters endure similar fates of brutal violation and coerced drug smuggling.
