Tsuma Netori: Ryoujoku Rinne – Episode 1 (ES)

Newly appointed married PE teacher Haruhara Ikumi begins work at the school while secretly investigating the mysterious disappearance of her best friend. Suspecting the creepy colleague Anno Shirou, she sneaks into his desk one night but gets ambushed. She wakes up bound in a secret "special guidance room" built in the old school building. Defiant at first, Ikumi hurls insults at her captor, unaware of the nightmare awaiting her. Shirou, who previously turned her friend into a sex slave, and the brute Tanba Gouzou begin Ikumi's brutal training. The episode features heavy restraint, sexual violation, anal play, enema torment, public stage gangbang with double penetration, and the first cracks in her proud spirit as pleasure and humiliation slowly erode her will. The cycle of endless indecency has only just begun.
