Pull up Hunter and Kate

I think back to the basement yesterday afternoon when I stumbled on Hunter and Kate getting down and dirty. I have the tiniest twinge of guilt that I'm about to be looking at such and intimate moment between them. I bring up the logs for the basement cam for yesterday. But I'm their father. I start loading the file from the right time. I'm supposed to watch out for them. The file opens. And this is freaking hot.

It shows a different angle from what I saw yesterday, from this shot I can see Kate's breasts swaying vigorously as her brother pounds into her from the rear. Her mouth is open in a look of mixed pain and ecstasy. My hand involuntarily moves to my crotch.
