You're girlfriend comes home after a workout very sweaty, you are secretly aroused by this! She eventually catches on that you like this and ends up being supportive and wants to help you out and affirm your fetish. she tells you how sweaty she is and how she hasn't showered for a few days. She tells you to plant your face between her cheeks and take in her smelly scent. she tells you that she wants you to fuck her stinky hole and of course you can't resist and you end up fucking her anally.
