Shirley will take the graduation examination recently.The trainer specially designed this desk for her to help her concentrate on her study.Although her hands were shackled, she could still open the book. Her feet were tied to the pole separately, and she could only sit there and study honestly.From time to time, the trainer came to scratch her armpit and soles and legs.He thought this can improve her anti-interference ability.When she was tired, he would take out the electric massager and shock her leg and ass.
