Girlfriend farting during anal sex

You feel like trying something kinkier with your girlfriend, so you suggest anal sex, but she keeps telling you how last time she ever tried that with a guy, she ended up farting big time. So, you tell her that you don't mind that and wanna try it anyway, get her all wet and ready, stick a finger or two in her ass to prepare it for what's about to come while she sucks on your cock, and then get the party started :) it all sounds like fun and games when she's moaning hard, but it doesn't take long before she starts...oooppps...farting on your cock real loud. Letting out all of that air seems to somehow turn you on even more, though, so you ask her to keep going and end up cumming real hard in her ass, all cause of her stinky farts. Guess you can say you have a brand new fetish starting today, dirty boy: fart fetish ;)
