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 whispering lewd words while holding her big tits in close contact with him, saying, ``I can't sleep for some reason...'' Furthermore, he forcibly removes the teacher's panties, who can't hide his agitation, and destroys the teacher's rationality with violent and rich licking and sexual intercourse, which is unimaginable from the usually modest girlfriend. Sperm is completely sucked out on a 2-night, 3-day school trip!
