My sister always borrows my clothes without asking. She's petite, the opposite of my tall self. When I caught her wearing my shirt again, I couldn't help but double-take—she was braless! And to make matters worse, she wasn't even wearing pants, her underwear was on full display! I was shocked, but also getting a hard-on. My sister noticed my sudden arousal and started fidgeting nervously. Until now, we hadn't felt any sexual attraction towards each other, but the atmosphere suddenly turned steamy, and we finally crossed that forbidden line! *This work is a selection from the previously released "HUNTB512" and features one actress.
