Abigail was encouraged  by her brothers moans and felt him rest a hand on her head. She bobbed her head back and  forth as she flicked her tongue over Peters hard cock. She managed to let out a few muffled moans. Abigail increased the pace and started to play with Peters balls, she looked up at him as if to check how she was doing.<br/><br/>She hadn't done this very often and the guys then finished rather quickly, she could tell Peter would was gong to be  a little harder to please. She let his cock touch the back of her throat a few times and increased the speed of her tongue. She couldn't believe she was doing this for her brother but concentrated on the job at hand.
