I was restructured from my company. After a long time, I was thinking of taking my time at home, but for me, Nanami, the neat and lullaby sister of the heavenly enemy, is in charge of this house during the day when her parents are away from work. I get in touch with the fearlessness, but there is a younger sister who is different from my sister that I knew. My sister, who had not even spoken for a long time, was actually growing into a hidden big breast!
