I have known I have an anal fetish for years, I love anything to do with anal at all. Anything. However, it was only recently that I discovered what my precise sort of niche fetish is, y'know how it seems everyone has something very precise. Well mine is gape farting to be precise. I would happily use the term anal sex fart, as that sums up what I love by stating that it has to be happening during the course of anal sex (regular farts I find disgusting; put them in the context of anal sex and it's the hottest thing ever, strange I know), without stating that gapes have to be present.
It doesn't have to be happening literally during anal sex, to the extent that the cock is in the ass when she farts. Ideally she's naked, in doggy, reverse cowgirl or piledriver (the hat-trick/the triple ace/the three amigos of porn. For me an anal scene with each of these three positions is pure gold), spreading her ass cheeks and intentionally pushing out with her anus every time he pulls his cock out, resulting in really nasty, dirty, naughty farts, with the noise and the lube and pre-cum being sprayed n' all. Or better yet an actual load of cum, as I immensely love anal creampies too.. I mean for me that's a gape fart/anal sex fart with cum shooting out too which is awesome.
Now as for why.. well okay I'll start by saying I'm quite a vehement non-conformist, I have a tendency to not like what the masses like and not conform to the conventions and trends of the masses, and this seems to extend to sex where I'm obsessed with anal, which is very non-conformist and against societies conventions.. I don't like breaking laws.. but I like breaking unwritten rules. It's pretty much all about psychology for me.. the psychological side of a sexy, gorgeous, beautiful young woman dressed up all fancy.. then you skip half hour ahead in the scene and she's naked, spreading her ass cheeks and farting into the camera. That kind of drastic change.. the concept that any sexy, beautiful woman in the real world, when in private might take cock up her shithole (Love dirty talk too, but I ought to go into that in another post), will spread her ass cheeks and try to gape her rectum open so the guy can actually look insider, and if the guy asks her to she might push her ass out and fart, on purpose. It's so naughty and dirty, and yet "regular" girls do this.. not all, but some. I say this because I have watched homemade amateur films in which this happens too.
I immensely love the whole concept of beautiful women playing with their poo hole ..that is a huge part of what makes it hot for me, that it's where her poo comes from, and she's playing with it, her anus, like it's a toy.. well it is.. a beautiful woman has another use for her own anus which is that it's a toy, and when they laugh while they're farting oh man it's the bomb! Even just like standing with a slight squat, sticking their ass out and spreading their ass cheeks, like in Buttman's Stretch Class (Alexis Texas - pure gold in this scene). She's naked, showing off her shithole like gratuitously, right into the camera, knowing that that one man actually represents/will be thousands of people.
Well this is a huge reason I love Adriano so much, I can tell his anal fetish is very similar to mine, and he encourages girls to dirty talk. Seems like he doesn't tell them to though, which I think is good actually. He just implicitly hints that he'd like them to by doing so himself, and seeing if they will reciprocate/copy him and do it themselves.
