天然巨乳ドジっ娘ナース！～毎日甘エロッ！中出し看護ライフ♪～

Protagonist Ryuya Yuki is a student who is not quite a lover with his childhood friend and next door neighbor, Mami Mizuse.

One day he eats a boxed lunch that Mami messed up while making and his body collapses.

Mami, crestfallen, confesses her feelings up to that moment. They come to realize each other's feelings and become lovers.

And then Mami dresses up in a nurse's uniform, and the too-sweet lovey nurse lifestyle begins!
