Lolicon Kyoushi no Oshiego Ryoujoku Keikaku

Kuroi-sensei of the S-district has his eye on a certain student.
It's been 6 months since he started teaching at the school and has earned
the trust of the pupils. But there is another face to this man...
Kuroi is a deplorable lolicon with r*pe fantasies.
