START-567 - Caught my best friend's sister going braless, couldn't help but stare at those massive I-cups and took advantage of her shyness.

While staying over at his best friend's house, Shiro catches the sister, Nano, walking around braless, unaware of the crush she has on him. He can't take his eyes off her massive I-cup breasts. When they're finally left alone, he teases her about going braless, and her shy, submissive reaction is too much to handle. He pushes her down and takes her right there in a mix of forbidden lust and first-love intensity.
