Rape X Minimal Mosaic Ravaged Teachers Yuma Asami (2009)

Yuma Asami plays a teacher who is ravaged by her students. She is forced into a gangbang scenario where multiple students, including Shirai-kun, Yokoyama-kun, and Hama-kun, engage in sexual activities with her. The central kink of this movie is the non-consensual nature of the acts, with the teacher being coerced into participating.
