[Ganmarei] Shinkou Naki Chijo Sabaki

Kurosu, the student council president whose colossal breasts and plush ass test the faith of every boy in class, prays over her lunch with pious devotion before spending the rest of the day as their insatiable plaything. Clad in her collar, she preaches chastity even as she offers up her ass to protect her vow, masturbates frantically between sermons she can't finish, and founds the 'Salvation Club' — a storage-room congregation where she endures a relentless gangbang of anal, double penetration and bukkake to 'wash away everyone's sins.' When two classmates finally follow her abandoned duties to the locked door, they find her drenched in offerings and welcoming them with open legs, moments before the expulsion notice seals her fate.
