Kickin the Dog
The act of of fucking a girl from behind while she's puking.
One night my girl was heaving her guts out after getting too drunk on Tequila. She was bent over the toilet with her pants around her knees, and her butt was sticking up in the air. Being the gentleman I am, I mounted her from behind, and each time she puked, the contractions were so amazing, I just couldn't stop Kickin the Dog
