The wife of my older brother, who I live in, drives me crazy... A week of temptation without bra.

I've been working for an electronics manufacturer in my hometown for eight years. I've been working hard in factory work, but recently I've been having a tough time managing my company, so I've been using a seven-day paid leave to start looking for a new job in Tokyo. Fortunately, my brother and I were told that they would let me live in the house, but my sister-in-law Maho is a bit of a natural person and usually spends her time without a bra... Her plump body, her soft, busty breasts are about to spill out. I wonder if I can maintain my rationality this past week...
