Lila stared into Mike's eyes as he continued kissing her asshole, the smell of her last fart still lingering in the air. Despite Mike's demeaning position, maintaining eye contact between the two was as natural as ever. There was absolutely no awkwardness, as the years of friendship had established a deep sense of trust between Lila and Mike. Lila was beginning to understand that she could use that deep trust to turn Mike into her ass bitch.
She thought back to their friendship. Mike had really been a good friend to Lila; he helped her with homework in high school, he listened to her cry, he had even supported her financially when she fell on hard times. The more Lila thought about their friendship, the more she realized that it was essentially characterized by Mike kissing her ass in some form or another. She sighed, content. There was no man that Lila would rather have as an ass slave than Mike.
That didn't mean she was going to go easy on him, or that she wasn't going to make him suffer through every fart she had coming. She loved watching him suffer for her and testing his devotion for her. As far as she was concerned, suffering for the entertainment of your mistress was simply part of the job description of a slave (a job which Lila had already assigned to Mike). At least it explained why Lila didn't feel bad that Mike's first kiss was with her feet, or that she farted in his unexpecting mouth after making him lick the dry, unwiped shit from around her asshole. Lila really did believe that Mike was, on some level, a slave.
As if to prove her point, Mike started gently lapping at her pucker. He looked at her lovingly, feeling as close as ever to achieving the first kiss of his dreams. The combination of tonguing her ass and looking into her eyes was vaguely simulating what he imagined to be the feeling of a lover kissing his beloved. Mike continued with his licks as Lila felt her second fart coming. She was giddy with excitement. "Ok Mike, this is your chance to redeem yourself," Lila said, "I feel another big fart coming". Mike stopped tonguing her ass and gave her a pleading look. She responded by giving him the kind of look that dared him to complain.
"To truly redeem yourself, it is important to make this fart exactly like the last one. Get your tongue deep in my ass and make a perfect seal around my asshole with your mouth, the way you did a moment ago." The moment of Mike's fairy-tale romantic kiss had come and gone now. Now, it was time to pay the price for that sweet moment (the same moment that Lila stopped thinking of him as her equal).
Tentatively, Mike put his tongue on Lila's hole, and applied some pressure, hoping to convince her that he was genuinely trying to get inside her farthole. She looked at him sternly, "I said, exactly the same as the last time." Lila wanted more. Disappointed that his act failed to convince Lila, Mike acquiesced and pushed his tongue deeper. To accomplish this, he needed to open his mouth as wide as he could and push it as forward as possible. Her ass cheeks made it more difficult to push his tongue deeper, but eventually he found a perfect angle, with his head down and his neck tilted back. This not only had the effect of getting his tongue as deep as it's ever gone, but it also formed a complete seal around her anus. Breathing through his mouth was very difficult, and he wondered where the fart was going to go once Lila shot it straight into him for a second time.
He looked up at Lila who was contorting her face and grunting softly. Oh god, Mike thought, what was he doing. She was concentrating so hard that she had stopped looking at him, barely focusing on anything but the raw sensation of pushing out shit gas. He closed his eyes and braced himself for another taste of hell. Finally, she began farting. Lila looked down at him grinning. It was a long, soft fart, like a balloon slowly leaking. From up there, it seemed as if Mike believed clogging her shitter with his tongue would save him from swallowing her fart. But swallowing her fart was exactly what he was doing while also getting a very good taste of it on the way down. If anything, his tongue was prolonging the fart, and making it escape at a slower and more controlled pace.
Lila's rancid fart kept going and, after about four or five seconds, Mike couldn't take it anymore. He tried pulling his face out, but Lila had anticipated an escape attempt. She quickly dug her heals into the back of his head. "Just where do you think your going, bitch?" she said. "I thought we agreed you were going to take my farts from now on?" Mike knew she was correct and that swallowing her farts was, in fact, exactly what they had agreed on. But that didn't mean he wasn't going to try to escape. He struggled to break free, but Lila wouldn't budge. She was going to make sure he swallowed the whole thing.
