Izzy moaned gently as her brothers massive cock thrust deep into her suckling mouth, tongue sliding slowly under the head to capture as much of that sweet, musky necter as she possible could at that time. She gulped it all down, taking the time out to wrap her tongue around his sensitive shaft, her lips gently sucking a little more as she caused the rest of his cum to fill her mouth. She eagerly gulped it all down, not realising just how good it really tasted until she tried it. Licking her lips she stood up and slid back onto the bed, her fingers slowly opening her soft, pink virgin folds for her -big- brother to spot. "Now...I think it's -your- turn to help me out!" she chuckled, opening her legs a little for him to see her entire body, and boy was it a great one; She definately was her mothers daughter.
