i'm the only one in the middle of 10 sisters! a week for the big family, the iwada family.

My name is Kenichi Iwata. He is the only man and eldest son of Iwata family, a large family with only sisters. I live every day when my frustrated sisters and irritating sisters are resented. Introducing my life that has always been fun and erotic. This time too, in addition to the noisy daily life, erotic cases and disturbances are going to occur one after another! As long as you live in this house, it seems that there is no time to rest!
