Letting out a groan, Matthew marvelled as he felt his daughter cumming on his hard cock.  Her body holding him so tight that he couldn't move his hips at all.  But that added tightness and her moans from Anna's orgasm, seemed to be just enough added stimulation to push him over the edge.  Cumming one last time deep into his baby's body, it slightly hurting as he felt his body milking his reserves dry at this point.  But still groaning with a smile as he cummed like this.
