Himari, the quietest student in the school, fiercely attacks the teacher who is nearing retirement age and has a secret crush on her! On the first night, she crawls under the teacher's futon as she goes to bed and seduces her by saying, ``I can't sleep for some reason...'' and whispers lewd words while touching her big tits! Furthermore, she can't hide her agitation and forcibly removes her teacher's pants, and destroys her teacher's rationality with a violent and rich licking blowjob and sexual intercourse that is unimaginable from her normally modest girlfriend. Sperm is completely sucked out on a 2-night, 3-day school trip!
