HBAD-480 For students overflowing with desire, restrained and trained into obedient flesh toilets, becoming holes to process sexual lust. Newly appointed big-breasted female teacher, Kawai Noka.

A struggling all-boys school hired a young woman with large breasts as a teacher to attract students. When she realized her body would be preyed upon by young men, she tried to resist but was tied up and raped, falling into a cycle of pleasure torture. The now-obedient female teacher, turned into a flesh hole, is made to take semen in her mouth for the boys' sexual release and has her vagina penetrated deeply by a hard young penis.
