A seemingly unlucky, plain beautiful girl. In today's terms, she's apparently called an "introvert." There's always one such student in the class. Oddly enough, such students tend to have particularly alluring bodies. Yukino, a student in my class. Her body is too detached from the world... Despite being a student, she exudes a charm that even adults can't manage, a woman born to bewitch men. For some reason, there's a feeling that if pushed, I might even be able to do it myself. Listening to her troubles, I naturally ended up pushing her down. With a silent student... we engage in sex regularly.
