部活での活躍で上下が決まるスポーツ系学園。
主人公は実力を秘めた男子水泳選手ながら、活躍する水泳部の女王・美琴から日々理不尽な扱きを受けていた。

そんなある日、ふとしたきっかけで美琴に鬼勃起する巨根を見られてしまう。
怯んでしまった彼女を見て、今までの鬱憤を晴らしてやると勢い任せにハメまくり、連続中出しで分からせて牝屈服させることに成功！

A sports-oriented academy where a person’s social standing is entirely determined by their success in club activities. The protagonist is a male swimmer with hidden potential, yet he is subjected to unreasonable, brutal training day in and day out by the swim club’s reigning queen, Mikoto.

Then one day, quite by accident, Mikoto catches sight of his rock-hard, massive cock. Seeing her flinch in intimidation, he seizes the moment to vent all his built-up frustration, relentlessly hammering her, blasting consecutive inside creampies, and successfully breaking her into absolute, submissive docility!

Convinced that these female elite athletes are completely powerless against a massive cock, the protagonist sets out to instantly corrupt the beautiful ace athletes of every club one after another with his giant rod. In doing so, he builds a personal fleshlight harem and secures a dream school life filled with non-stop breeding.
