The unconscious eroticism of dedicated girls. When we were students, we used to look at them from afar with excitement at their swaying breasts, the elastic of their bloomers digging into their buttocks, the outline of their underwear showing through their sweat... We've recreated the sight of these girls working hard at their sports, unaware of our gazes, in a real school! Please enjoy the authentic atmosphere! [※There are no sex scenes in the main story.]
