haha i think its funny, no reason to be embarassed...anywho, you're gonna lose that bet, what made you think girls dont fart? umm we're human too? yes.
one time i whipped it out and my gf started to gimme head and i let a huge fart go cuz i was holding it but she started to get me off so i didnt wanna let it go and ruin the moment but i had kind of forgot about it cuz i was thinking of the pleasure and it slipped out and she just looked at me with my cock in her mouth with a look of awe on her face.man it was classic but then i covered it up by rubbin my foot against the air mattress and i guess luck was on my side cuz it made the exact same sound so i was clear and still got off but luckily it didnt stink
