[PPPE-223] During the three years that this busty student was enrolled, I trained her until she was no longer able to resist and became an obedient sex toy. Karen Yuzuriha (Censored)

Karen is targeted by a corrupt teacher with a twisted mindset. Even though she needs to pee during an exam, she is not allowed to go to the bathroom and is forced to urinate. The training escalates further in order to turn her into his personal sex toy. He makes her cum with a remote vibrator in the hallways and stairs where other students are passing by. He makes her cum inside while she is concentrating on her studies. He draws graffiti on her body to show that she is his property. Trained like a human urinal, Karen gradually begins to realize that she has been reduced to a slave.
