My story's borderline scat which isn't my thing but I can see how reading this could get seen as such. But I love big girls with fat filthy asses. So the better the smell, the more I'm hooked. If I can clearly smell it while fucking in doggy style, she's good.
I've been seeing this girl that's a complete slob and have been really getting her smells and just straight up bend her over or and praise her nasty bhole. I'm I smell and lick her armpits too but not as much because of all the fat folds to navigate through compared to spreading her cheeks. She's a sub and doesn't mind getting her ass sniffed and ate but I don't think she quite gets how turned on I am by the lack of hygiene. I demand her not to shower for a few days but she doesn't do so for long and still has bidet she uses to clean herself on the regular. so I didn't experience the the degree of filth I wanted quite yet .however, She gave me a key to her apartment recently since I work closer to her than my place and Ive come by on my lunch breaks or after work unannounced where I bend her over in the couch, peel her shorts down, and breath it all in between her fat Boulders of ass cheeks, her asshole is definitely dirtier and better smelling when she doesn't expect company around so I need to feed more into that, or just straight up demanding her to not wipe, which I might ask for a holiday gift so she tries it and gets used to keep herself dirty for me.
I have some ass wins I can post but again idk if we're taking the olfactory aspect of this thread that far.
