I'm being fucked by a student. After school of a blackmailed female teacher

Nanaha is a popular Japanese language teacher at the school. She couldn't refuse and ended up having a relationship with Matsumura, an honor student who had feelings for her. He is blackmailed by Takada, a delinquent student who accidentally saw this one mistake and secretly took a photo of him. "If you listen to me, I'll delete the data." However, his requests gradually escalate... Restraint and toy toys, continuous bukkake blowjobs, infinite gang rape, after-school is hell for her. "Please... stop now," the clergyman is trashed without any hesitation.
