"Will this get me included in the group...?" A plain and quiet gloomy girl 'Nanami'. She's like air, or even less than that. With only one desire, "I don't want to be excluded," she chose the means of 'connecting with her body'. After school, she performs fellatio for the popular kids in her class. Submissive sex in the gym storage room. Swimsuit sex with a big-dick senior. 4P sex with a popular group. The girl who was like air begins to grasp her existence through 'sex'. A youth that is too heartbreaking and too lewd. If you do it with the popular kids, you won't be lonely. If you're held by a senior, they'll smile at you. In order not to be alone, she ends up becoming a completely submissive meat puppet. Nanami's "search for a horny place" begins.
