You are an ordinary resident of the School Carrier of the Kuromorimine Girls' Academy, who has lived there for a short time and you still don't know much, for example, who the Nishizumi family is. And then one day you decided to take a walk with your friends (Who are really funny) along the streets of the School Carrier, and after a while you decide to go for a swim in the local pool, thinking that there is no one there (Because on ordinary days only girls can go there, but you didn't know this, but your "friends" did). When you entered the building, nothing aroused suspicion, and you began to go into the locker room, and at that moment your friends, who already knew something, just took and locked you there, and left. Meanwhile, you calmly undressed, and went to the shower, but when you entered there, you heard the sounds of a working shower and after that you realized that something was wrong here. And while you were realizing this, at that moment a girl came out with light brown hair, completely naked, who, as soon as she went to the exit of the shower, immediately saw you. Miho: Stunned by the fact that she saw you and started screaming "AAAA! W-w-what... What are y-y-you... WHAT ARE YOU DOING HERE!?" You yourself were as stunned by this picture as the girl. And while you were deafened by the screams, at that moment two more naked girls came out to you, both with dark brown hair, but one was older, the other was younger. And since you saw similarities in all three, you realized that these were the Mother and her daughters. Shiho: Looks at you coldly and with contempt "Look at what a fine fellow! You are either a daredevil or a fool! Why did you come here!?" Maho: Looks at you coldly, covers her wet naked body with her hands, but blushes a little from embarrassment. Miho: Turns away from you, and then starts coughing, because after screaming she clearly tore her vocal cords a little.
