Hello! This request is for: Leondy4Life
Contains:
• fatal x 404
• smut
• also I decided to do this Halloween themed, regardless of if I manage to publish it on Halloween or not-
• hehe CPAU mentioned, also as follows- mentions of spiked drinks because of swap-
• the singular swear: bullshit

Gravestones lined the driveway's yard, two well-sized jack lanterns stood on either side of the patio. You know, after the first Christmas party, it actually was sorta fun..so why not do a Halloween party this time? Of course, this time Geno would make sure a particular fiend doesn't spike any of the drinks so fresh had been assigned as their guard over the snack table. He also made sure that there was no invitation fraud, that way not too many people would show up. It would mostly be him, reaper, sans and papyrus, error, fresh, 404, fatal, swap, fell, sci and fatal.
     Since this is a Halloween party everyone was expected to dress up in costumes- it would be a relatively small party so hopefully none of the shenanigans from Christmas would ensue, it'd just be a nice, casual party. The doorbell rang, Reaper getting the door. As expected, papyrus was at the door in his skeletor costume, carrying sans with him. "Greetings godly sans! Nyehe!" It's probably still weird for papyrus to wrap his head around the fact that there were so many alternatives of he and sans. Sans was just in a ketchup costume- it's like those horrible banana costumes but ketchup version. They are often on time, so nothing too out of character yet, they were welcomed in, Geno leading them around the house, mostly just giving a tour of his new house since getting to the Omega timeline and all.
   8:00 arrived, more than half the guests having arrived by now. It was definitely noticeable that 404 and error seemed to have some sort of theme;  nerd stuff probably. Well, error was dressed as asgoro, 404 dressed as Giffany.. and fatal later arrived as Monika, so yeah, they all just cosplayed stuff from TV shows or games. For the most part things were chill, everyone ate, carved pumpkins, and watched horror movies,or Halloween-themed movies/cartoons.
They were on their second to last movie of the night, it being nearly midnight. Swap and papyrus had fallen asleep, it being way past the times they usually went to sleep at. Reaper and geno were getting particularly cuddly, error sitting on the floor, head leaning against the couch cushions. Fatal was on the arm of the couch, not specifically a comfortable place to sit, considering you have higher chances of getting a little nudge and being sent to hell; the floor. Fatal and 404 were quite comfortable around each other so when he was offered to sit on 404's lap, how could he say no? The guy isn't a creep or anything so he didn't mind.
   Like any cheap horror movie, there are always questionable scenes. 404 grew flustered.. perhaps something else seemed to grow too, poking fatal from behind. He tried to move so that both of them would be comfortable, sure he was really strong and could get pretty much whatever he wanted but that didn't exactly work with specific wants and needs, like romance or, well, doing a little bit of fooling around. He and fatal weren't exactly dating, but they also weren't single, they were in some sort of cursed romance limbo and the boundary line between dating and not dating is being used as a pole for pole dancing.
    They've shared many kisses before, they've cuddled, they've seen each other naked, that doesn't sound platonic, does it? Eventually though.. these two snuck out to the bathroom, on the guise of "getting towels" because papyrus spilled water. Once inside the bathroom, fatal was pinned to the wall, being pushed up onto the sink's counter. Fatal just hummed, kissing 404 on the forehead. Fatal didn't really like talking that much, mostly because people barely understand what he was saying. Although 404 could probably understand better than anyone ever could.
       "Cute skirt." 404 teased, although he was also wearing a skirt. Cosplayers do not kid around when crafting magnificent pieces, that's for sure. Although a little awkward at first they eventually got to it, both of them leaving hickies in various places.. including places that shant be named for there are multiversal censorship guidelines. 404 gently rocked into fatal, stealing kisses as he went. The skirt from previously was folded up not-so neatly on the floor. Neither of them really had a preference for being rough, they were the type to really take their time. So as follows, the pace was slow and nice. Nothing that hurts, but not boring. Just right.
As time passed 404 had gotten a bit faster, fatal fumbling with 404's bow on his costume. It was sorta funny how fatal's moans had some sort of echo or reverb to it. It may seem embarrassing for fatal but personally 404 loved that to death, it was such an interesting thing. The others were likely wondering about where they went or if they got the towels, but those who knew were likely somewhat disappointed for this behavior..in someone else's bathrooms too, jeez. Although, it's not like they'd really try to interrupt those two. Mostly because they don't want to witness such a scene or have to hear it up close if they wait at the door. Ain't nobody wanna see 404 getting all.. intimate with fatal on the bathroom counter. 404 gave one last kiss, pulling out as a mess dripped down fatal's legs.
          "Tired?" 404 asked, grabbing a washcloth and running it under some water. He wiped it over fatal's thighs, being thorough and cleaning up. Sure the location was questionable but he didn't own this house so he wasn't going to make a mess, although knowing Geno, that washcloth is getting burned, never useable again. He had been given a prompt nod from fatal, scooping fatal up into his arms and grabbing some towels too. Technically, that spill was probably dry by now, but at least they can bullshit their way outta this one, just..very badly.
     Geno watched as the two got back from the bathroom, a face of disgust gracing his features. He really should stop having these parties, something always goes weird or wrong.

The end, hope you enjoyed!
