Warning to the Reader: This is a work of sadistic grossdom. Lila will not be nice to Mike, and she will do nasty things to him!
-------------------------
Lila removed her hand from the back of Mike's head and was pleased to see that he kept his face tucked up against her ass (he did so because he was trying to hide his tears from her). "Ok, so now we will work on mouth-to-mouth kissing," said Lila, "except instead of my mouth, you'll be practicing on my asshole." Mike wanted to refuse and tell her that her ass was absolutely filthy. But then he would have to explain why he was fine with rubbing his face all over her butt the past twenty or so minutes. Mike was afraid that, if she found out how filthy her ass really was, she would lose all respect for him. So, he decided that he had better just go along with the make out and finish quickly. He choked back his tears, and slowly pulled his face out of her ass.
Unfortunately for Mike, Lila was well aware of how filthy her ass was and, the more he subjugated himself to it, the less she respected him. Though she didn't know why, she knew that she wanted Mike's tongue deep in her ass. She wanted to see how far she could take things.
"Mouth to mouth kissing is like a dance: you want to cycle between kissing the top part of her lips, and the bottom part of her lips," she instructed, "so for you, kiss the top and then the bottom of my asshole. Open your mouth slightly, and let your lips drag across my skin. When you are kissing the top of my hole let them drag down, and when you are at the bottom let them drag up," Lila liked the sound of her advice. She really thought she was being as good of a kissing instructor as you could possibly be when your student could only practice on an ass. "When you feel like your lips have reached the center of my asshole, alternate."
It was like she was barely even putting an effort into keeping Mike's fantasy alive, almost like she was trying to make Mike painfully aware of the reality of the situation, namely, that he was about to kiss her shit-caked asshole rather than her soft plush lips. He looked at her ass crack once more and shuddered. Mike tried to instead focus on the nice parts of her ass: how smooth the skin was, how big it was, how it was both firm yet bubbly, how it curved beautifully... anything but the little specs of shit dust wrapped in layers of dried sweat that covered her ass crack. He closed his eyes and leaned in and began kissing as Lila instructed. Lila spread her cheeks to make her asshole easier to kiss.
Mike tried to breathe out of his mouth at first, but after inhaling a handful of tiny shit particles, some of which he almost gagged on, he decided it was perhaps not such a good idea. When he started breathing out of his nose, he experienced the absolute worst smell of his life. He couldn't believe such a beautiful woman could produce such a vile smell. The next five minutes was a battle between Mike's willpower and his gag reflex, as he started familiarizing himself with all the little details of Lila's ass.
Lila, on the other hand, was in complete heaven. Not only was Mike's rhythmic kissing oddly soothing, but also downright empowering. Here was a boy who thought he had a chance at fucking her because he was her friend, and instead he was kissing her sweaty, poorly wiped, rank anus. She knew he was having a terrible time (she did catch him crying after all) and loved the situation all the more for that fact. Why couldn't the little bitch stand up for himself? Who let's someone wipe their ass with your face? Just then Lila's stomach grumbled slightly and she felt the urge to fart. She thought about how funny it would be to blast one right in his face, but, even for her, that joke felt a little too mean. So, she held back, and let Mike continue kissing her ass.
Mike was surprised to find that he was actually starting to grow accustomed to the smell of her ass. Once again, when he focused on the nice details, and made the best out of his shitty situation, he started feeling good about it. His hot friend actually took off her pants and her underwear for him! Sure, he she wasn't letting him see her pussy, but then he thought about all the times he fantasized about Lila's butt, and there it was, in all it's glory! Though he tried to suppress the unrealistic delusion, he occasionally hoped that if he did a good enough job on her asshole, he could prove to her that he was worthy of kissing her lips. He thought that maybe if he impressed her with his ass kissing prowess, she would want to make out with him for real.
Lila looked back and saw a blissful Mike, eagerly worshipping at her ass. She was surprised that the same man who was crying into her ass was now seemingly having a good time. To confirm whether Mike was really enjoying himself, she glanced at his pants and saw that he was indeed erect. Lila had to supress her laughter. This asskisser's tiny little boner was the most pathetic thing she's ever seen! What about her filthy ass was turning him on right now? Was she that hot or was Mike secretly an ass slut? Either way, she decided it was time to truly test Mike's devotion to her ass. She considered feeding him her fart, but still couldn't bring herself to do it, even though holding it back was starting to get uncomfortable. Instead, she decided she was going to get him to clean her ass with his tongue.
"Now start working some tongue slowly into the kisses" said Lila, "at first just tease me with little flicks, then stick it in deep." With Mike's erection clouding his ability to think clearly, in his excitement, he licked her ass all the way from the bottom to the top of her crack. He immediately regretted it. The taste in his mouth was indescribably bad: Salty, bitter and just generally vile. "Easy there cowboy!" said Lila, "I said flicks! Remember you are supposed to be 'kissing my mouth' not eating my ass."
Mike felt stupid. He wanted to be kissing Lila's face, not her ass. But now, he was convincing her that he wanted to be eating her ass instead of kissing her mouth! Of course he didn't want this, he thought. Especially after having just tasted it.
