My girlfriend of about a year and i were hanging out, we had pizza for dinner and went back to my place. She was really gassy.

She knows about my fart fetish, so she allowed me to smell her ass for a while.
Then she took off her bottoms and layed on top of me in an upside down 69, putting her ass on my face.
she rubbed her asshole onto my mouth, where i opened my mouth and prepared for her farts.

she ripped three HUGE farts in my mouth. The taste was horrible.

after each fart she would smother me under her ass.

it was a good night.
