Des:Miyu is a sullen college girl with little sexual experience but actually fantasies about being fucked by a guy with a big dick. Although she has a boyfriend, Makoto, who is as serious as herself, she is not at all satisfied with her sex with him. One day, at the suggestion of Professor Oshima, I went to a research camp with my boyfriend and fellow alumni. Miyu hates the domineering and clingy Oshima, but in the training camp she is forced to share a room with a big dick and skilled erotic techniques.
