The story follows a young male protagonist who finds himself in unusual circumstances, tasked with providing sexual education to a group of female students. This forms the first part of the series, focusing on his instructional and increasingly intimate interactions with them.
The narrative later shifts to a different scenario where the protagonist engages in a series of erotic encounters with a group of bratty younger sisters. The manga explores these dynamics through explicit, hentai-focused storytelling, detailing the protagonist's experiences across these two distinct settings.
