Fandom: Sword Art Online. Story idea: Asuna is a cheating slut. Contains: Cheating, oral, straight sex. This is an idea that was requested to me. All non-one shots, and even some one-shots, will be put here first, then made into actual stories by popular vote only.
Asuna had waited for Kirito to fall asleep, then logged on and headed off to meet Agil. She'd been waiting for this since she'd woken up, and grinned excitedly to herself as she ran to where they had said they'd meet. They'd been doing this for over a month now, meeting up inside the virtual world for sex. They could usually only do it a few times a week to avoid suspicion, and it was barely enough to satisfy Asuna.
She remembered feeling guilty about it near the beginning, but as she walked into the room at the inn and saw Agil there waiting for her, she couldn't remember why. She smirked, pressing a few buttons on the hovering menu next to her and causing all her clothing to vanish off of her body in an instant. Agil looked over her lovely body, grinning as he grew hard at the sight. A press of the button did the same for him, leaving him naked on the bed with his thick, ten inch cock standing at attention.
Asuna dropped to her knees in front of Agil taking his massive cock in her hands. She needed to use both to stroke it, and licked the tip of it as she did. She loved how big it was in her hands, and stroked it harder and faster as she took Agil's tip into her mouth and sucked on it hard, her tongue swirling around it as she her hands pumped along his shaft.
Agil moaned, letting her hand it. He knew she took as much pleasure from pleasing him as from being touched herself, so there was no reason to try and instruct her. She'd gotten incredible with her mouth, not that Kirito would ever know that. She began to push her head down, taking more of Agil's cock into her mouth and sucking harder as she bobbed her head along his length, taking it deeper inch by inch.
Agil loved how enthusiastic she got about trying to take his entire length. She hadn't been able to do it the first few times they'd hooked up and it had driven her crazy. Now though, with her experience, she managed to take his entire cock into her throat with only a little effort. She forced herself not to gag from the size of the length hilted in her throat, and continued to suck and move her head, pleasing Agil until he came.
When he did reach his limit, Asuna held onto his hips as she swallowed his cum, loving it and loving how much came from it. She sighed happily when she came up for air, them climbed onto the bed, laying on her back with her legs spread open for Agil. Agil grinned, getting above her and lining his cock up to her eager pussy. He pulled her hips back as he thrust his own forward, pushing a few inches into her hard.
Asuna moaned, loving it. She gripped the bed as Agil began to thrust into her, forcing his cock deeper into her with each thrust. Asuna started moaning his name shortly after he'd gotten half of his length inside of her, and by the time he was pumping the entire length of his massive rod into her, she was a drooling, moaning mess, unable to say or do anything except moan for more or plead for it harder.
She came twice before Agil reached his first climax, pumping a huge flood of cum into her and pushing her into a third climax. She panted as she laid back, but knew they weren't done. Agil could keep going for as long as Asuna could, and she didn't plan on stopping any time soon.
The only potential for this story is firstly to have another chapter where Asuna and Agil fuck in different ways and meet up IRL for sex, as well as possible Kirito finding out and responding by cheating right back.
