Gyaru seito no ryou chikubi name kairaku akume ni kusshite futari no rezu petto ni nari sagaru onnakyoushi 2.

Two gyaru students are caught engaging in lesbian acts on school grounds. When their teacher tries to reprimand them, they lash out, pin her down, and rip off her bra—exposing an outrageous bust. Obsessed, the girls torment her nipples with relentless precision, breaking her down into their submissive lesbian pet. Wearing vibrating nipple toys, the teacher wanders the library and is led through the classroom by a nipple leash. The climax features a heated strap-on lesbian threesome.
