Gakuen no Ikenie: Nagusami Mono to Kashita Kyonyuu Furyou Shoujo

Based on the adult game by Erectlip, a priest abducts a girl with the aim of making her forsake her companions and become part of his religious sect. Her refusal to comply results in the cult members enforcing a form of divine punishment through nipple penetration. A friend arrives in an attempt to rescue her, but this intervention leads instead to the friend being subjected to anal intercourse.
