Seito-tachi ni Sarashimono ni Sareta Onna Kyoushi Hen 2

Tachibana-sensei was extremely poised and well-mannered, as the teacher of privileged students at a rich private academy. When news got out about what she was seen doing in the ladies restroom...

One exploit begets the next. Tachibana-sensei masturbates naked in the classroom and streaks on the school roof, takes an enema in the boys toilets for everyone to see, is r*ped and verbally abused, and posed in humiliating ways, all to the delight of her students. Where does it end?
