Well fuck...my mother?

I came in from a long days work and found my girlfriend screwing my mother.  actually, my mother was on top, so it'd be the other way around.  Shit, who cares.  My girlfriend and my mother are fucking as I type, and I have to hope they don't notice the video camera I set up on a TV tray outside the bedroom door.

What should I do?

why do these people always think that whatever stupid shit they make up on the internet will be believed? Seriously, man, if you're actually filming your mother having sex, you're a sick fuck. No one in their right mind would want to see their mom getting it on. Nasty fuckass.
