My name is Kenichi Iwata. Be the eldest sons in the only men of the big family "rock country house" where there is only Sisters. Send daily life tossed about by the Younger Sister which is Elderly Sister and Pranks of the frustration. Introduce the life that only an erotic event cuts for my pleasure secondary to the last time. An eroticism case and a Ran case break out in addition to the Nichijou which is an uproar this time very much in sequence! As for the time when chi ● po feels relaxed, there seems to have no me somehow or other as far as I live in this house! ！
