In'yoku no Choukyou Gakuen ~Osananajimi ga Netorarete Inran Maid ni Ochiru made~

The downfall of classmate Rina Kurose, who somehow gets seduced and sex trained into a lewd bitch maid!?
Her weakness is used against her to turn her into a slave for one week...
At school she publicly masturbates, a vibator teases her during gym class, and in the school clinic she takes a d*ck between her tits and in her mouth!
Humiliation forces her actions, but her soul is invaded by lust that was always there...
