Roadside Blow-out
While fucking a girl doggy-style, you quickly switch holes and stick it in her ass as deep as you can, pull out and tell her she's a quart low, then kick one of her legs out from under her, making her fall to that side like a a car with a blow-out.
"Mr. President, Michelle doesn't seem too happy with you today. What did you do?"

"Last night she complained about my health care plan, so I gave her a wicked roadside blow-out in the Oval Office."
