A hospital director's girlfriend with strong fetishistic tendencies appears in 'emutte Girl Lab.' She usually engages in intense sex that feels like being raped, and it seems she has become addicted to it. An M girl who derives pleasure from accepting a man's desires decided to appear at her boyfriend's (main) request. She takes the offered dick whole and wraps her long tongue around it during fellatio. While having her neck choked and her face stomped on, she demands hard piston-like thrusts. This true masochist bared her instincts and exposed her shameful behavior.
