"But you're right it does." It doesn't happen to me ... usually," she said, her eyes glued to my bulging robe."I don't see why not," I replied. "Nothi...ng wrong with your looks." (A little white lie, but excusable, I thought.)"You're too kind, but I know I'm no great shakes in the looks department," she said."It's not all about looks," I said. "Sometimes it's personality, other times opportunity." So you er ... find me ... um ... attractive John?" she asked, swallowing slightly, her eyes never. "What I said... those words," she asked in a soft voice, "did they... excite you?" Yeah, Mother!" he said, enthusiastic, his eyes burning on her beautiful tits.She lowered her eyes to the front of his pants, seeing they were still wet from her cunt. The bulging of his cock and balls made her tremble with hunger again. She ran her tongue over her lips, and started toward him. Billy caught sight of her crotch, and she heard him suck in a sharp hiss of air.Standing near him, Donna leaned down. She rubbed her slit slowly with her open hand.She was saying something but I couldn't make it out. Who was she talking to? Then I saw him. Her younger brother Tim was sitting on the edge of her bed. He also was naked. He had his thin four inch hard on in his hand massaging himself slowly while he watched his sister dance naked. I pulled my prick out of my jeans and began to stroke it slowly while watching. This was better than I had expected. I really wished that I had remembered my camera.I. I open my already sore mouth and she shoves the panties deep down in my mouth. I almost gagged. I could taste that they weren't fresh underwear but I wasn't about to mention that to my deranged sister.She stands back up and starts walking around the bed, smacking her hand with the whip. I'm aching for her to say something to kill this silence."Last night... you called me.... what was it? Your slut? Your little whore?" She asked with a dark tone. She placed the whip up to my chin and motioned.
