Sans AU One-Shots

❀Slash❀ || tuesday. (HG)

Pairing: Demon! Slash Sans x Summoner! Female Reader
Prompt: It's the demons' heat week, and (Y/n) offered to help them out with their urges.
Type: smut
Length: 2.8k words
Background: This was in Her Guardian as part of a spicy week-long bonus thing where each of the guys got a day of the week with Y/n to claim her. The goal of the heat week is procreation (i.e. making babies) and after mating, the heat urges go away. The Stars are a lot more respectful and restrained, thus less likely to make their intentions obvious like the Bad Sanses and seek Y/n out, but the heat still affects them (just less obviously). | Takes place on Tuesday - after Swap's
Notes: Lucky Y/n - the joys of being in a reverse harem, I suppose. Them being a demon only changes how tall they are (at/over 6'4"), their power (they're much stronger than humans), and how they see Y/n (among other things I explore in my full-length story that aren't relevant for this smut-shot). I tried to remove any information that pertains to the events of Her Guardian so you can read this as a stand-alone story and understand everything.
SOMETHING TO NOTE: Slash is in his human form for this. See above pic for what he looks like 🫶

"Watch out!" (Y/n) shouted, but she wasn't fast enough, forcing her to watch Slash blow up right in front of her. A loud groan came from her chair behind her and she glanced back at the boy she was leaned against with an apologetic grin. "Sorry."

"Not your fault creepers are so quiet," Slash muttered bitterly, hugging her in his arms before tapping the 'A' button on his controller to respawn back in the bed of their shared Minecraft house. The two of them were cuddled up on (Y/n)'s bed where Slash had positioned her Xbox and monitor so they could play together. Slash was a great stand-in for a chair—(Y/n) had her back leaned against his chest as she sat in his lap, and he looped his arms around her to hold his controller in front of her, resting his head on hers. It was cozy and his body was warm, and he was in his human form just so she could be more comfortable.

"Did you lose a lot of stuff?" Her character walked over to the start of the mine Slash's character disappeared down almost 30 minutes ago, and Slash sighed.

"Not nearly enough to risk going down there to get it," he said dismissively. "I'm still impressed you heard the creeper when I didn't." He looked down at her with wide green and yellow eyes, and she smiled faintly.

"I used to play this game a lot growing up. It's one of those sounds that triggers my fight or flight reflex." She let out a quiet laugh as he grinned, and she shifted in his lap, making him stiffen.

He cleared his throat, pointedly looking away as he nodded solemnly. "I see, it's your survival instincts honed through experience." He made it sound much more respectable than it truly was, and she glanced back at him as her character headed towards their shared house.

"Do your instincts help when you play video games?" Surely real life experience had to translate over to gaming prowess, right?

Slash flushed, awkwardly rubbing the back of his neck. "Well, not really, but I'm a lot more impressive back home."

(Y/n)'s whistled. "You're already impressive here, so now I'm kinda curious what you're like back in your universe." She leaned back into his chest as she tilted her head back to look up at him, and he smiled confidently.

"I'm a force to be reckoned with. Even Dream said he's impressed by me!" His eyes sparkled brightly. "Trust me, if you met me back home, you would've been swept off your feet a long time ago." He swept his hair back with his hand as he winked, and she felt her cheeks redden under his gaze. He had boyish charm mixed with genuine ability, and knowing he couldn't lie made her all the more impressed. But his seemingly easy confidence made her curious how much of it he could back up.
