Dududu
       this contains smut, so it will contain exactly that although I feel that use of a pink vial would somewhat count as alcohol usage? I'm not too sure, but that's how I'm going to describe it- Also the person who requested it, sorry for not being able to appropriately tag you in the chapter! For some reason Wattpad decided to be an unfunny goober and not make it so that I'm able to do that, sincerely sorry!
It's been several years since the truce, of course some things have changed considering the lack of fighting between dream and nightmare.. although that never excluded pranking each other with... questionable little jabs and such. Of course as always ink and error still fight but had to put aside their own differences, it's not that error was on nightmare's side, it's just that error has gotten quite tired and ink is basically somewhat out of commission due to their last physical fight that directly lead to the creation of the truce. It was a warm, sunny day, birds were singing, flowers were blooming, and nightmare had just woken up due to a less than pleasant noise of dust and killer going at it again due to some petty squabbles. He didn't want to deal with that first thing in the morning unless he had his coffee first, so, like every morning he went and started up the coffee machine.. not aware of ink's latest prank that was originally intended for error until dream suggested that they could do both error and nightmare.. naturally, the effects of that godforsaken vial are relatively normal under small dosages. What dream and ink didn't know is that error doesn't drink coffee, while nightmare was a crippling addict of the caffeine kind.. although he hates energy drinks with a burning passion.
          He poured himself a cup of coffee, the first dose. Noting a difference in taste, it didn't mess with the bitterness of the coffee but whatever was in the coffee added a sort of smoky caramel flavor to it, which nightmare didn't really mind for once. Although, that didn't stop him from wondering why it was there. Once finished his cup of coffee, he went and resolved the fight. Throughout the day, he had managed to drink a whole coffee pot's worth of contaminated coffee, leaving him in a bit of a haze, stumbling about, flushed face, perhaps a little bit sleepy, but one huge particular thing; desire, not just any desire though.. romantic desire..or, considering nightmare's lack of means to show it; sexual desires. 
      He sat at his desk, his mind blurring out the words that were being spoken to him by killer until killer had to give him a gentle shake to get him to refocus on the the report he was giving on the status of a particular Underswap timeline that he just finished terrorizing. He refocused, just slightly..his eyes seeming to sort of just follow killer, he was feeling really weird. Eventually killer finished his report, sitting down besides nightmare. "You've been acting off boss, I know you're not really much of a drinker- but are ya drunk or something?" Nightmare had a strict no alcohol or illegal substance policy, he wouldn't easily break his own rules unless maybe for a special occasion or if he was going to use acid to melt someone's face off or something along those lines[illegal substances count as actual acid especially since nightmare doesn't want to have a hole in his floors], killer was well aware of this so it was weird to just see nightmare acting like this and just..spaced out in a way. 
          "I feel weird, I think someone did something to the coffee.. someone must've been trying to poison me." He rubbed nightmare's back, listening to what he said, from his own personal experiences he's seen nightmare drink poisons straight up and never get too affected, he figured his goopy body must be absorbing the poisons, so what could be affecting him right now if it wasn't poison? Before killer could say anything more, he noticed their proximity, his face flushing red as he could feel his own soul start to pulse just a little bit quicker than it would usually. Nightmare slumped over, leaning on killer a little bit..killer was nice, warm..and next thing he knew he had already kissed him. It wasn't in his correct judgement to do so..and killer didn't seem opposed, but he knew he'd be probably quite apologetic afterwards since this is quite.. unprofessional behavior.
       Killer had no intentions of pushing back, he knew this was kind of odd of nightmare..like, really odd, but he liked it, he liked nightmare. A few more kisses ended up exchanged, nightmare panting as he had come to realize the position they were in, killer's back against the desk, his arms on both sides of killer. "I don't know what's wrong with me today..but..is it okay, to continue..?" He didn't know much about any romantic kind of stuff, he didn't even consider himself a romantic person so in his mind he didn't think it was possible to like killer..maybe he really was drunk? Maybe by the time this was over with, he'd find out that these feelings were simply just silly and dumb and that he ended up playing with his own feelings? He really didn't know, but he didn't want to think about that right now, thinking sucks.
      "Yeah, it's okay boss!" He gave nightmare a quick peck on the cheek, he knew nightmare was an old school person so he didn't really think there'll be anything too out of the ordinary, he was nice and predictable...like a hurricane. Just as he thought out one thing, he felt a cold hand take his soul into their hands, delving their fingers beneath a couple rings in the soul, feeling the warmth along it.. everything nice. And killer? He was practically melting against that desk, nightmare had always been curious about how something worked- he used to deconstruct pens just for fun..and killer, he was always curious about killer. 
              He took killer, hauling him up and setting him down on the desk after clearing away some paperwork so that none of it got crumpled or..soiled. While one hand kept messing around with the soul, rubbing his thumb between rings, gently scratching against the center, he took this time to sort of just..get ready? He smothered killer's face with kisses even allowing himself to go lower and give gentle neck kisses. He wanted to start things off slow and he surely did take his time, leaving little marks on killer's shoulder and neck, sometimes doing a little nip on the soul, making sure to avoid the center since that would've caused more hurt than it would pleasure and he didn't intend to hurt killer. While nightmare was busy doing that, killer was also busy, feeling up nightmare's tentacles, massaging the base and giving gentle squeezes, he figured that those must've been heavy on nightmare's back so it must've felt nice to have it relieved like this. 
    As time went on, things started to progress, killer over the desk and being quite loud. His fingers caught against the desk, digging in and leaving marks as he could feel each little thrust, bucking his hips in return. Their bodies were pressed so close together that killer could feel the warmth between them. Nightmare seemed to have such a gentle roughness to him that was just..so good. Nightmare could really just do this, at this pace forever, and killer would be more than content. This kept on for awhile, certain spots taking killer's breath away while his fingers were definitely making their own love marks into the desk, he was quite vocal and so their activities together would probably be questioned tomorrow. Nightmare's movements were starting to quicken, just slightly, but killer could definitely feel it. He knew nightmare must've been close to done, although this was fun it was probably best they turned in for the night, especially with how sore he was going to be later. 
      Eventually everything came to it's end, killer resting in nightmare's bed as nightmare was busy heavily sanitizing his desk since he sometimes slept at it. Once thoroughly sanitized, he joined killer in the bed and pulled the blanket over themselves, slowly drifting off to sleep.
      Horror, who's room was right next to nightmare's, had heard everything. He grabbed his food stash of crackers, a blanket, and his headphones, and made his way to dust's room. He wanted to sleep in peace and dust, despite his night terrors, was much more peaceful than whatever had happened next to his room.
The end! Hope you enjoyed :D
