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?

Dude, why dont you just jump in and fuck em both? Take some viagra, so u have enough stamina to stick it in their butts. Drill em long, drill em hard, and cum on their faces.
*i am so demented, 4chan has fucked me up*
