Matthew sat back and just watched with a smile.  Just watching his own daughter lower her sexy wet pussy down onto that hard cock.  Seeing it disappear deep inside her body.  Letting Anna just start to ride that cock like that, able to watch her body moving as she bounced on her uncle's cock.<br/><br/>The sight in front of him was so erotic and kinky.  It was just making him want to feel more of his daughter's body, pleasuring it with his own.  His earlier disgust at all this fun long forgotten now.  But for now he was just taking his time to recover, knowing that there would be so many more chances to fuck his daughter soon enough.
