Shiratori Yu is a beautiful woman secretly sneaking cute sisters secretly shooting and sending happy everyday to Okazu.
But every day as usual, Susumu Doskebe who came up to the house suddenly will end.

The moment I met, my sister Tsukimi was caught barely tied up and my
sister Narumi got tired of “getting along well” ….
Her phrase was inspired by it, even to her elder sister and sister who should be gentle and adults to come close to changing his eyes!
So, a horny new life with quite aggressive 4 sisters will start now !!
