I've only had experience with dog farts, I would love to have the pleasure of a mare farting right on my nose. However, that will most likely stay a fantasy. And whether or not i like its depends on the dog, my first fart experience was a beautiful female Rottweiler. She belonged to my girlfriend's (at the time) mother. We had been there many times, and I had a major crush on the dog. The first time I was alone with her I immediately sat on the floor and sniffed her ass (just cause that's my thing, you can judge if you want). She smelled so good, she had a stronger smell than the ones I had sniffed before, but that's just turned me on more. She seemed to,like me doing it too, cause she backed up pushing her hole against my nose, at this point I could barely control myself, I pulled back a little, and she pushed back more, the all of the sudden (without noise or warning) i feel her tailhole contract and relax and feel the warm air blow up my nose and across my face. I felt it before I smelled it. I instantly lost it and came in my jeans. I dont really remember the smell exactly, but i think it was more the experience that I enjoyed. I did get another chance in another day, and,went for it again. However, my GF walked in while I had my nose buried in the dogs behind, and an obvious stain on my pants... That was the end of that... I may have just been so caught up on the moment that I like it, but its something I have found myself wanting again, and fantasize about. Ive had it happen one other time with a male dog. It was more of a curiosity sniff than an attraction... And he ripped it as soon as my nose touched him. I gagged, and almost puked, but when I reflect back on it, ill admit I do get turned on by it, even though it was horribly gross.
