With Mom out grocery shopping sis accidently walked in on her brother playing with himself with a pair of her silky slick panties in his hand . Working them up and down . Wrapped around his cock. She was shocked and puzzled for a mere moment and said " ahem" for him to hear her and know that she had found him masturbating. With her newest pair of panties no less that she had worn only once or twice. He must have fished them out of her personal hamper or maybe they were lying on her bedroom floor. Never the less ,two minutes later , she's naked . Back in her bedroom with her brother naked on her bedspread . His cock in her hands and her mouth biting his sack to his delight.
