He couldn't remember the first time he smelled an ass, but for as long as he could remember it was his most private and humiliating turn on. He must have smelled his own at first, but as long as he could remember he loved the sharp, sour stink of a bottom. For the record, he wasn't scat or dirt, and it always annoyed him when people who didn't know or care described the rich stink of a butt as smelling like "shit". Not only was it meant to demean or degrade the idea, but it was just completely inaccurate. The smell he loved wasn't at all the dull smell of shit. It wasn't even really the smell of sweat, although that wasn't bad in his opinion. It was a bright, sharp smell, reminiscent of cheese or vinegar. It was so far removed from "dirt" that he never associated the two.
He knew it was an unusual fetish, to be sure. In his early experience with porn, there was literally no mention of smell whatsoever, even in the raunchiest anal porn he could find. Later on, as the internet opened the world to more and more disparate communities and interests, he started to encounter it more, but even then it was more of a throwaway before a rimming scene. This was fine and did the job, but he did wonder if maybe he was alone in this particular niche.
As such, he kept it to himself for the most part, especially in his early dating and interaction with women. Indeed, years before his first fumbling attempts at dating, he had been curious about the phenomenon. He even though maybe it was just his own smell and his alone, and that other people's rears didn't smell at all? Curious to test the idea, he found an opportunity while playing with the neighbors one hot summer evening.
It had even a tradition on summer nights for the neighbors to gather and play hide and seek. It was on such an evening that he found himself crouching behind a large pine tree in the neighbors yard with their eldest daughter, Nancy. She was 19 that Summer, and while a fairly attractive girl overall, she did have a very nice bottom. He had definitely noticed and fantasized about it when playing before, as the game offered many opportunities to see her on all fours with her ass in the air. He had often wanted to sneak up and see if he could smell her butt, but either someone else was there, or could see them, or he simply lost his nerve.
This particular night, though, the opportunity seemed perfect. Needing to try and sneak a look at those doing the seeking, Nancy peered below the lower branches on the tree, and in doing so assumed the perfect face down ass up position, her back deeply arched and her ample bottom raised and presented perfectly. Her jeans were a faded blue, and they were stretched tightly over her round and pushed out butt, the seam diving a bit into the crack to give it a heart shape. In later years he would find this position to be an immediate turn on and the perfect way for an ass to be presented. At this moment, however, he recognized his chance to test his theory. They were the last two still not found, and the others were in clear view. No one was there to see them, and she was in perfect position. This was the perfect chance. Who knew when it would come again?
Slowly, silently, he crawled behind her. She was busy checking for the lookouts, so she didn't see or hear him. He approached her gorgeously arched bottom, then looked around to see if anyone else might have an eye on them from some other hidden purchase. He didn't see anyone, but at this point he didn't care. He slowly slid his face toward her butt, his nose aiming the seam of her tightly stretched jeans. Much to his shock, he was able to smell her before he expected, several inches away from her actual bottom. He inhaled and took in the first ever scent of someone else's ass. It wasn't exactly what he expected, the jeans seeming to give it a twist of their own. That raw stink was in there, but it had an almost bitter tinge to it as well. He was so shocked by this that he was nearly hit by her him as she rocked back, raising her head but staying on all fours. As she settled, she arched her back again and pressed her bottom out, waiting for something to happen beyond the trees in the further yard.
With her butt still presented and pushed out, the natural arch spreading her cheeks beneath her jeans, he dipped in again for another smell. He needed this one just to prove he hadn't imagined the whole thing. While she wasn't as splayed open as wantonly as she had been before, he still got a strong stink from the seam.
She stayed like that for several minutes, and he smelled her the whole time. The sour, bitter stink from her bottom seeming new and almost alien every time he Inhaled. As he thought about it later, he reached an even deeper level of excitement when he acknowledged that her bottom smelled so much that it could be smelled through her jeans. This thought, even as he was going in for that initial sniff, had never occurred to him. To be honest he didn't think he would be able to smell her, or at least if he could he thought it would be faint. The depth and intensity of the smell, even through her pants, was a revelation. This was proof that his fantasy was real.
That summer, he managed to smell Nancy several more times, as well as some of her friends who would be spending the night with her. To his disappointment, not all of them had the same deep smell that Nancy had. Some were much more faint and could only be smelled in the area of the seam right over their butthole. Still, he did manage to smell them all at some point. Each time was confirmation that the smell wasn't just a fluke, or something that only affected a few girls. This was a real thing!
As he got older, he found ways to sneak sniffs off of girls he was dating. While there was no tried and true method of smelling them with their jeans on, which had taken on a more significant time in his fetishes, he did notice that doggystyle was was a very reliable method of smelling a girls bottom. He also noticed that, without the jeans, the scenery was much more like his initial expectations shine. Sharp, sour, cheesy. And it wasn't all the girls. Sometimes they didn't smell much at all, although this was the exception to the rule.
Like his fascination with their stink permeating their jeans, he was surprised that he was able to smell them from behind without having to get close. The smell would waft up to his nose, generally seconds after he took his position behind them while they were on all fours.
As he searched for material about his fetish online, he did notice that many of the videos and stories he came across presented the act of smelling an ass as a submissive act. This made some sense. It certainly could be seen that way in the light of degradation and submission. However, he had always seen it somewhat differently. Ever since he realized exactly how strongly Nancy's bottom did stink, he thought about how she would feel if she knew her most private area could be smelled so easily and strongly. Nancy wasn't particularly unhygienic, so he imagined this would probably be a source of embarrassment and humiliation for her. Likewise with his partners. If they knew their bottoms, when raised and opened, were as smelly as they were, would they feel embarrassed? There were times when he thought they had to be able to smell themselves as well. If the smell was getting to him that strongly from a couple feet away, it had to have reached them too. None of them ever mentioned it, and he was still far too shy to admit to this fetish, so he was left to wonder.
He finally admitted his fetish to a girl with whom he had an intense and emotional relationship. She was highly sexual, and it was then that they experimented with the first halting steps of kink. She had asked him once for his deepest, darkest fantasies. He was clearly embarrassed to admit it, fearing being called a freak or weirdo. Sensing his shyness, she grabbed a sheer sash from a nearby robe and tightly wrapped it over her eyes, blindfolding herself.
"Sorry. That was none of my business." , she said before telling him that her body was his and he could do what he wanted, and she would stay blindfolded as long as he wanted. He could do whatever he wanted to her body, within reason, of course, and she had no need to know. He had her get on all fours and arch her back. She knew, being sexually aware, that this position was a turn on for many men. She arched her back and presented her ass perfectly, her round cheeks pulling open with the rounding of her back. He was nearly faint as he feasted his eye on her hole, red and raw and stinking. He placed his hands on her buttocks and spread them a bit more, only to have her drop her shoulders to the ground, arch her back at a seemingly impossible angle, then reach back and pull her cheeks apart with her hands.
"Just go slow and use lube, please.", she whispered, assuming he wanted anal. Then she spread her legs wider, allowing for an even deeper arch to her back. Her bottom was almost aiming straight up, her asshole stretching slightly from the wide ness of her spread cheeks. He leaned in, put his nose at her hole, and sniffed. The stink was pure and almost overwhelming. His brow broke out in a sweat. She steadied herself on her knees, then reached in deeper to her crack and spread herself even further. The smell was now permeating the room. She had to be able to smell it herself, but she shower no sign of hesitation or resistance.
"I'm yours. ImI'm here for you. I can't see and don't deserve to. I'm here to be used by you how you want. I'm blindfolded so you don't have to wrong about me judging you. I wouldn't anyway but I'm going to stay blindfolded so you don't have to worry about what I want. I'm yours to use, and I don't deserve to know if my knowing causes you embarrassment. If you want I'll blindfold myself every time and that way I'll never know what you're doing and I'll proudly hold my bottom open as long as you want"
Her voice was raspy, as her breath had dried her throat. As she finished she settled again, widening her stance even lower and allowing Her ass to open even further. Her butt stink was thick in the air now. He was sure she could smell it. Anyone who walked in would be assaulted with the smell. I might have even gotten outside his room. He was more turned on than he thought possible. He stroked his cock, feeling it grow. Ire rigidbthan he ever thought possible. He spit onto her asshole, when she felt it, she adjusted her angle to what she thought might make her an eaaier target. She reached into her crack and began to swirl the spit into her asshole. She rubbed around the edges, then pulled her fingers to her mouth and lubricated them again. Reaching back she stuck her fingers into her red, stinking hole and pushed them in tothe knuckle. She left them inside her for a moment before she started to move them in and out, fucking her ass with two fingers. She got more spit, then reached back and thrust a third into her hole. He was stroking himself like a piston. He began to run his xoxo up and down her crack. She pulled her fingers from her bottom, then thrustvand arched her cheeks up into the air at an obscene angle, anticipating his point of entry. She pulled her butt open with her hands, and he settled against her hole, pushing gently into her. She let out a slight gasp, then reached back and spread herself even further open for him. He slowly edged into her, but his raging heat was too much to control. Within a few thrusts he began to thrust harder. She didn't make a sound or move, her only response being to arch her back. Ore and spread her cheeks wider with her hands. It was inevitable that he couldn't last long., and a few thrusts later he erupted. He stayed in her, buried deep as he emptied himself. She held her position, presenting her bottom for use at as extreme an angle as he had ever seen..A few moments later he collapsed, gasping. True to her word, she held her position, holding her cheeks apart and offering her bottom for his pleasure.
He then noticed that the anal penetration had made the smell even thicker. Hwe butt had filled the room with its stick, and it continued to do so as she held herself open. This realization caused him to get enforced again, and soon he was rubbing his cock against her crack once more.
That night, she stayed in position and opened herself for several seasons. He finally lost track. Even when he told her she could relax she opted to remain like that, her bottom thrust out and exposed, her hole being presented for whatever he wanted. When he finally collapsed from exhaustion and in deep sexual satisfaction, he gently pulled her into her side. Even then, she demonstrated her submission and kept the blindfold on, even retying it when she felt some slack later, tightly binding her eyes under the silky black fabric. She kept it in the whome night and into the morning.
This cemented in his mind the correlation between the stink he loved and submission on the part of the one who was being smelled. She didn't show any sign of embarrassment even as her butthole filled the room with its unmistakable scent, but the fact that she had done so with no hesitation and no reaction at all even when he had finished gave him that association.
