Your girlfriend gets home from the gym after a sweaty workout and as soon as she gets into the bedroom with you she can smell anus in there. It can't be you as you've just got out the shower, she feels really paranoid that her ass got too sweaty in the gym and checks. She rubs her thong along her crack and asks you to smell it - wow it stinks of dirty cheese. You're still not sure though it could just be that her thong smells not her actual anus. She asks you to get a closer inspection and she whips her thong off. She winks her ass hole at you before you shove your nose deep inside of her ass hole and inhale deep breaths. Brown nosing your girlfriend with your only choice of oxygen through her musky anus, you can't believe how turned on you're are getting at the putrid stench of her sweaty ass hole. She spots your erection and encourages you to jerk your cock while you take in deep breaths of her cheesy anus. Getting hi off her anal musk. Just as you're about to cum she flips onto her back and winks her anus at you one last time, and begs for you to cum all over it. Now you're addicted to her sweaty ass hole and she has marked you as hers with the scent of her anus.
