Used to be a dancer at a local club who'd rate a 5 at best on almost anyone's scale. About 35 at that time, flat chested, buck teeth, crazy eyes, no ass, skinny as fuck. Complete lack of interest on my part. Until one day she was the only girl in the club on day shift when I was the only customer. I was bored, she was bored, and our conversation eventually got around to the kind of sex she liked. Her exact words were "use me however you want." Being the weak willed type that I am, I figured it was worth one afternoon half hour VIP (at $100, the cheapest in town at that point) to see what her deal actually was.
No more than 5 minutes later, I was dumping my load down her throat after fucking her mouth like a pussy with her head lodged in the corner of the booth and her hands pinned against the wall. 20 minutes after, I was doing it again, though I was more relaxed sitting on the couch while she face fucked herself with my dick. I swear, that woman had the greatest lung capacity of anyone I've ever met. The sight of her pushing her mouth all the way down on my dick, the sound of her gagging occasionally, even without me holding her there, got me back up and cumming in probably the shortest refractory period I've had in decades.
Turned out her pussy and ass liked being rammed hard as well. We managed to meet up again several times over the years before she completely disappeared about the time I met my ATF.
