PPPE-223 在这位巨乳女学生就读的三年里，我不断调教她，直到她再也无法抗拒，最终成为了一件听话的性玩具。卡伦·柚木

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.
