Summary
Sans wasn't planning on getting himself a slave. There were just too many mysteries surrounding the human to just let them go. Sans was going to find every little secret of theirs if it killed him. Make no mistake, it was likely to kill him. If only the human would stop sucking up to his brother.
Or in which, the author is sick of people using slave fics to make reader a broken/submissive doll and Sans a dom butthead, so author makes their own story and gleefully tramples over some cliches.

Summary
When you receive an offer to move to the newly-established monster city-state, it's an easy decision, especially in the wake of your divorce. You need a fresh start. You need to meet new people. You don't expect to meet quite so many skeletons in particular, but a new friend is a new friend regardless of how much flesh they have.
And you're no influencer, but it seems obvious that you would post about your journey online, right?
But life in Mt. Ebott City is a lot more confusing than you expected when there are such clear divisional lines among monsters themselves. Sometimes it seems like even monsters of the same species are from entirely different universes...

After Dark - One Shots by Fells_Kitten (SquirrleyCow)

Summary
Some one-shots from the "Don't You Remember?" series. Honestly just done for smutty and fluffy fun ;)
If you wanna jump in here, be my guest. :D It's going to be much less dark than the rest of the series. This will mostly be scenes with an established threesome of female reader, UF!Grillby and UF!Sans. But there might be some random encounters later, I dunno. Just updating this whenever I get a new idea. Kind of like an OVA?
*This WILL have BDSM! And probably past-traumas mentioned but not explicitly described. There'll be warnings in the chapter headings if they are.
*FIC title name from "After Dark" by Mr. Kitty, because i'm terrible at titles.

Summary
"Oh now you're just being hurtful." His bony hand rests against the freezer door.
You chuckle as you stand upright. You manage to turn before he slams the fridge door shut and shoves you against it. You smile lustfully up at him as he bares his teeth in a hungry leer. His hand pins you by your collar bone, just inches from your neck.
"Maybe I want to try the hurting for a change?" You ask as he leans closer.
He freezes. "What?" He asks in disbelief.
You shrug as he steps back. "I mean, I'm constantly covered in bruises, bites and blood. Not that I mind. But I wonder sometimes..." His face falls as you push against his chest until he takes another step back. You blink and look up at him. "What you would look like tied up, bruised, begging for release?"

Summary
Your stomach rumbled. Making you move ever so slightly. It was nearing your feeding time anyway. You ever so slightly lifted your head off of your battered arms to give an ice cold glare to the glass window that separated your room to the rest of the asylum. The glare you were currently giving the window was one of those glares that could render a full grown man helpless. You smirked once more at that thought. Though this time, your smirk was plainly visible to the people currently monitoring you from the safety of the other side of the glass window you were currently looking at. That's right. They were safe from you with being on the other side of the glass.
Things to look out for:
~ Blood and gore
~ Mentions of violence
~ Cannibalistic notions
~ Horror topics
~ Upcoming intimate scenesWARNING: This story is very graphic, and not for the faint of heart! There are mentions of upcoming rape scenes, graphic depictions of violence, profanity, and a whole lot of blood and guts. This is rated M for a reason. If you have not already read the summary for this fanfiction, I highly suggest that you do. You have been warned, read at your own risk. This is geared for mature audiences only.

Summary
Your friends had been trying to convince you to get out and meet somebody for a while. After waking up one day and realizing you were twenty seven, hadn’t gotten laid in five years, and were considering buying a cat so your apartment didn’t feel so empty all the time, you realized they might be right. So, you sign up for a blind dating service, absentmindedly shrugging and clicking yes when it asked if you would consider matching with monsters.
You couldn’t have expected your blind date to be a skeleton. Or that he’d actually be very pleasant company. In fact, you liked him enough to keep seeing him, but… even as you start to feel interested, he kinda creeps you out?
You’re caught up in a weird frightened romance, but thankfully Sans is a patient guy.
