Michigan Whirlpool
This is when you are doing the piledriver during sex. The guy is about to cum he pulls out, as he is cumming he puts his ass to her vagina and fills it with a big hot fart as he cum on her face.
The other night I was rawdoggin my girl in the piledriver and I gave her the best Michigan Whirlpool. It stank so bad and I got some in her eye...
