爆乳女将の誘惑 ～片想いのあの子へダイタン告白！でもムッチリボディの熟女が気になって…～

Yamaha Shuuyuu wanted to confess his feelings for a girl he had feelings for at a school-sponsored overnight stay event, and to have a relationship between a man and a woman so that he could graduate from being a virgin.

However, things change when he meets the proprietress of the ryokan where he is staying, a beautiful mature woman named Arakawa Sayako.
Shuuyuu becomes aware of her as a woman for one reason or another.

He puts aside his one-sided love for the girl he wanted to confess to, and began to seek out Sayako.
