Matthew let out a moan as he felt his lovely and so very sexy baby girl take more of his hard cock into her mouth.  This was just so kinky and taboo, and felt so amazing.  Watching his brother playing with her body like he was, he knew the Anna must have been enjoying his touch.  Partly cause he knew Mike knew just what buttons to hit to get a girl really going.  But also because he could feel those soft vibrations of her mouth around his hard cock.  "Mmm oh yes baby, just like that feels so good."
