My brother's wife, who lives with me, drove me to the brink of madness... I went a week without wearing a bra. (Kanno Maho JUY-934)

I've been working for an appliance manufacturer in my parents' area for eight years now. I've been working hard at the factory, but recently the company's management has become very strict, so I decided to use my seven days of paid leave to go to Tokyo to look for a new job. Luckily, my brother and his wife let me stay at their house, but my sister-in-law, Maho, is a bit of a natural woman and doesn't usually wear a bra. She has a voluptuous figure and soft, large breasts that look like they're about to fall off. I wonder if I can keep my wits about me this week...
