He got into bed first and took up residence against the wall. The bed wasn't quite built for two, so when I joined him we were quite literally pressed skin to bone.
I tried to hide any bit of nervousness that I had as were were glancing at each other. We must have both thought the same thing, where do we look.
I tried to keep my eyes off his chest and at least above the collar, which was surprisingly difficult to do. I felt his chest move against mine with each breath and it started messing up my breathing too, it trying to sync with his. His yes would lock with mine a moment before trying to find something else to look at. It was awkward and I was half willing to turn the other way.
"So, uh, comfy?" Sans spoke.
It felt like his voice was right in my ear, thus I shivered.
"Y-Yeah. The bed is smaller than I remembered..."
"Yeah, me too...maybe I can make a little room."
I raised a brow as he shifted a bit, putting an arm under my head and the pillow then pulling me a bit closer from the edge of the bed. Now I was even closer to him and could feel his heartbeat faintly.
"Any better?" His cheeks were still tinted and I realized he made a pretty bold move.
I wasn't normally one to be flirted with, actually it was the opposite. Him flirting with me, especially this type of move, was not going to fly by without me flirting back. I Pressed further into him and laid my head on his chest. It shockingly felt full and soft, and I wanted to run my hands over it.
"Much better." I managed to squeak out and I forced my eyes shut to look relaxed.
His heart was racing a bit under those thick bones. It was clear he hadn't expected me to push back. Was he going to try further, or would we leave it at this for our flirting game? I would be a little disappointed if he had stopped, but he went the extra mine to use his free arm to hold me.
"Yeah, me too."
I could feel my heart racing his, but things never lasted as they should. My mind decided to exit the flirt highway and take a more dangerous route. I imagined what it would be like to feel his heart in my hand, being squished between my fingers. How I could watch him poof into dust with one quick squeeze.
A laugh, not my own, left my throat and echoed in the room. My voice betrayed me soon after and followed up with a sentence I couldn't take back.
"Too bad there's no knife this time, Trashbag."
His bones went rigid and he shot up to look at me. He looked like he saw a ghost as he faced my body.
I felt out of control for the moment as I grinned wildly back at him, my eyes feeling like they were open to full capacity. What was I doing? What was I saying?
"Frisk...?" His voice was lined with warning.
Just as fast as the change came, it went. My eyes filling with horror now instead of whatever they had in them a second ago. My smile was gone and replaced with quivering lips.
"S-Sans...wh-what was that?"
