I have my sexy dirty underwear on and fart on my teddy with it on then i go to the bathroom with the fart stains & smell on my underwear and piss with the same underwear on. Now its extra filthy???????????? i'm gona use the same underwear for another week to keep pissing with and farting on so the smell lingers, maybe even get a few orgasms to add the extra sex cum smell ontop of the smell it already has????????
