Nothing. This is too hot to consider stopping it now (Gassy Ass Cuckolding Route)

[NOTE: Making this a similar for now, but diverging, path from the other one, because while I'm up for playing with things like gas and bad smells for kinky erotica, I know that's not everyone's jam.]

"What?" Emily asked, a note of challenge to her voice. She'd gotten annoyed of waiting with Lily saying nothing.

She could still... she could undo this later, right? Yeah, later. "Nothing, sorry. I hope you have a good day at work." Then Lily flopped on the bed, deciding to finally gives her legs a rest.

Seeming to take a second to swallow her annoyance, Emily just said back, "I hope you have a good day off. I still love you, even if it's platonic now." It was meant to be a balm to any hard feelings, but to Lily it just felt like another dagger in the back, as Emily went on her way to preparing for work.

It didn't just hurt, though. Why does it feel so good? What's wrong with me?

What's wrong is you were never good enough for her to begin with. Of course she jumped at the chance to date me instead. All your insecurities were right. You're a loser. I'm perfect.

That voice, speaking to her again, sounded just a little louder this time. Is that really my ass? Or is it... some part of myself, taunting me? She wasn't sure how she'd even be able to tell. Not sure what else to do, Lily just crawled back into bed to rest up.

About half an hour later, Emily had gotten dressed and ready for work. "Okay, I know you have a date with Jake today, but please make sure to clean your cum off the floor before that. I know you're tired now, but like... this is my room too, y'know? And I don't really want your cum staining the carpet if we're not dating."

Lily had almost fallen back asleep, but with a pang of hurt she nodded. "Yeah, I'll clean it up, I promise."

"Good. Now, can you flip around so I can so goodbye to my girlfriend?" Lily assented without question, turning face down. Emily flipped up the covers and kissed Lily's ass, one cheek and then the other, before digging it for one on the 'lips'.

But as she did, Lily felt a pressure growing that she'd missed, and her ass jiggled a little as a quiet toot of a fart escaped her cheeks, right into Emily's face. Lily, embarrassed, started to apologize. "Sorry, Emily, I didn't feel it coming, and-"

"Why are you apologizing?" Emily said with a giggle, though Lily could hear the sound of... arousal? Yes, arousal, in her voice. "My girlfriend is just saying goodbye to me." Then, to Lily's shock, she took a big sniff and gave one more kiss before leaving for the day.

In the aftermath of that show of affection, Lily could have sworn she felt her ass heat up a little, though she must have been imagining that. Lily sunk into the covers, cuddling a pillow, and began to nap.
