After being left in the detention room for the last time, Nagisa was supposed to do her homework, but instead, she got really horny and decided to play with her slit and a small vibrating sex toy, which was hidden in her back pack.
This time, her teacher had something else in mind for her. As her physical education class started, and Nagisa was already in her t-shirt and shorts, he summoned her into the detention classroom. But, when she came there, she saw someone else and her teacher was gone. Before she could ask the man what happened, she got captivated by his hard boner and totally captivated. As one thing led to another, very soon she was all over his hard boner showing her sucking skills.
