After working for eight years at a local electronics manufacturer in my hometown, I've been diligently putting in effort at the factory job. However, due to recent financial struggles at the company, I've decided to use my seven days of paid vacation to travel to Tokyo and seek new employment opportunities. Fortunately, I managed to ask my older brother and his wife to let me stay at their place. But my sister-in-law, Mao, has a somewhat airheaded personality and usually goes braless. She has a plump, soft body with massive, jiggling breasts that seem ready to spill out at any moment. Can I really keep my composure throughout this entire week?
