On some rare occaisions i caught the smell of a hot chick farting....
I guess they try to keep it inside or leave the room and go to a place without other people before they let go of some steam...
But I tell you IF GIRLS fart it usually smells twice as bad as a cloud produced by a guy, because the guy immediately releases some gas when the pressure is building up, while the girl usually focefully kept it inside for a couple of days, allowing the intestal bacteria to add further rot to the smell....
Ofcoarse this doesn't apply to all girls and it's just my own perception. In fact I know a sleezy fat girl (fat but well shaped body) at my work that asks me sometimes to pull her finger and then she releases some steam with an incredible trumpet sound....
I really like this girl for her bold ways. She acts a bit like a naughty boy and i always have fun with her.....
