Sans X Sans Novels & Stories

I wouldn't trust one specific site to have everything. People tend to flock to different platforms based on what they want to see and how they want to engage. If you're after curated, high-effort pieces, sites like Pixiv or even certain tags on DeviantArt used to be decent, but you have to dig through a mountain of other stuff. The real gems often get re-posted on aggregator blogs, which is how I usually find them, but then you're dealing with broken image links and dead sources. It's a mess.

Honestly, my method is following individual artists on Twitter once I find one style I like. Their networks usually lead to others with similar vibes. That's yielded way better results than scouring a single host. A lot of the truly dedicated work for that pairing ends up on private servers or locked accounts anyway, so it's more about building a feed than visiting a 'site'. The public hubs get flooded with low-effort meme versions that drown out the good stuff.

Man, thinking about 'sans x reader' themes is like opening a floodgate—so much depends on whether you're vibing with his 'Bad Time' mode or the more laid-back 'comic sans' version. There's a massive chunk of fics built on the 'who did this to you' trope, where the reader character finds a damaged, injured, or emotionally shattered Sans and becomes their caretaker. It's this immediate, high-stakes intimacy, bypassing small talk and getting right to the bone-deep hurt/comfort. These stories thrive on the tension between his usual detached humor and genuine vulnerability, letting the reader be the one person he finally lets his guard down around.

Then there's the whole domestic slice-of-life angle, which honestly has a huge following. It's the opposite: imagine Sans as your lazy roommate who hates doing dishes but will teleport to the store for ketchup. The appeal is in the quiet, mundane moments—sharing a bowl of Easy Mac at 2 AM, falling asleep on the couch during a bad movie marathon. It makes a cosmic prankster feel attainable and grounds the fantasy in something cozy and low-pressure. The humor is softer, the angst is minimal, and it's just… nice.

I also see a surprising number of 'royalty/royal guard' AUs where the reader is from the Surface or a different kingdom. It flips the dynamic, making Sans a reluctant bodyguard or a noble with hidden power, which gives authors a sandbox for political intrigue and forbidden romance. The reader navigating court etiquette while Sans makes terrible puns behind the king's back is a specific flavor of fun. It's less about the core Undertale mechanics and more about transplanting his essence into a high-fantasy drama.

Lately, I've noticed a spike in 'found family' themes, where the reader gets integrated into the whole skeleton household with Papyrus. It's less exclusively romantic and more about building a weird, loving unit. Those fics often have the warmest tone, full of cooking disasters and sock-stealing shenanigans. That's probably the theme I find myself re-reading the most when I need a pick-me-up; it feels like coming home.

Alright, so this is a bit of a minefield, but I get the ask. You're probably looking for that specific 'Flowerfell' or 'Handplates' style angst with a side of spice, right? The main hub used to be Archive of Our Own, obviously, with all the proper tagging—filtering for 'Underfell' or 'Underswap' AUs helps a ton. But let's be real, the really explicit, super dark takes sometimes migrate to dedicated forums or personal blogs that aren't indexed by Google.

I'd warn against the temptation of just Googling 'sans frisk nsfw' on a whim. You'll hit a lot of low-effort, poorly written stuff and more pop-up ads than you can shake a stick at. Tumblr still has pockets of it, but you need to know the right blogs, and they often get shadow-banned. Honestly, my best finds have come from Discord servers dedicated to UT/DR smutfic; people share links to Google Docs or Pillowfort there. Just be ready for wildly varying quality and some truly out-there AUs.

At the end of the day, it's a niche within a niche. You gotta dig, and sometimes you strike gold with a writer who really gets the dynamic—the power imbalance, the guilt, the whole 'Judge' thing twisted into something very not-for-kids. I've come across a few gems that way, but it's not for the faint of heart.

Seriously, though, check your tags on AO3. 'Sans (Undertale)/Frisk' and then 'Explicit' is your starting point.
