After the private lodge Suuichi planned to
study at for his summer break burns down; from a meteorite strike, he
takes up the offer from his sister(Nanami) to stay with her in the dorms
over summer break. While in the bath with his sister he is caught by
three other female inhabitants of the dorms and is subsequently taught
"lessons" by each of them, partially in part to agreeing to call each of
them "nee-chan".
