Inverted Particle Accelerator

When you're banging a chick and she's getting bored, just grab her by the ankles, stand her up on her head and ram your five digit fuck friend down her fudge factory, thus causing her cum closet to quiver in delight.

Oh shit! What happened to your hand dude!

Well, I gave Karen the inverted particle accelerator on Tuesday and she came so hard her chocolate coated cock crimper broke every bone in my hand.
