Andrew sighed against her, laying ontop of her for a few moments before reluctantly pulling out. Then he flopped onto his back beside her, staring up at the ceiling. His arms folded behind his head to open his ribcage, allowing him to draw in deeper breaths as he slowly covered. "Its amazing we didn't have more children, really." He murmurs, turning his head to look at her. "I can't count the times I've cummed in you, or the amount of sex we've had over the years." He pauses, biting his lip. "Do you think ours have followed in our footsteps?"<br/><br/>-----<br/><br/>Peter couldn't help but moan as his sister really began to work on his thick cock. He didn't care why she was doing this and he wasn't going to complain about it. His cock twitched a few times in her mouth as it pressed to her throat again. And then he leaned forward, sliding his other hand down her front to squeeze one of her breasts. "Keep going..." He murmurs. "You're going to make me cum soon." He adds, squeezing her breasts even more. Then he pressed his hips forward a little, unable to control the motion, wanting to feel his length penetrate more of her mouth.
