A sister walks into the living room wearing nothing but a tiny pair of panties, leaving her huge breasts in the open. She sees her brother sleeping on the couth with his erect penis sticking out of his pants. She couldn't help but be surprised at his size, she thought it had to be at least 12 inches, quite the manly penis. Her curiosity gets the better of her, she walks over to him and kneels between his legs to get a better look.
