Dirty! 🍋(Nightkiller)

A/N: THIS IS EXTREMELY EXPLICIT PLS DON'T READ THIS IF YOU'RE A PURE ANGEL.

It was quiet. Killer was just scrolling on his phone while Nightmare, on the other hand, was busy reading through his papers. The two were in his office, the dark one in his desk, the shorter on the mini couch. Both were pretty much lazying around (if you count that reading is lazy). The air was cold but the two didn't mind it.

After a while of scrolling through social media, Killer got bored. He looked up to his occupied boss and began to smirk. He had an idea in mind and if you knew him personally, it was probably something stupid.

"Hey, boss..." The black-teared skeleton called out and the dark skeleton looked up from his paragraphs. "What is it, Killer?" He responded and immediately, a smirk escaped from Killer's expression. "What if I were to... "accidentally" send someone a pic of my d1ck or cvnt if they want? What would happen?" He asked and Nightmare's expression turned blank.

"Killer, what in the actual fuck is in your mind?" He asked coldly, his expression looking as angry as Killer had expected. "But what if I sent it to you? Then what would be your reaction?" Killer further questioned, getting a little too smug and shifting his position into a more...erotic one.

Nightmare immediately paused, his face lighting up in cyan.

"C'mon, Boss! I'll send both pics if you answer me." Killer pestered jokingly and Nightmare sighed in annoyance before looking away. "What you're asking is a stupid question and your negotiation tactic isn't exactly appealing to me." He spat.

Killer gasped, faking his being offended. "So you don't want me to send nudes to you?" He asked, trying to hide his laughter. "Send the pics first, then you'll know what will happen." Nightmare randomly blurts out and Killer's face was immediately bright red. "Wait, huh? Is that a promise?" Killer asked, sitting properly.

Nightmare smirked at him and replied "I don't know, is it?". Killer gasped at that, knowing what Nightmare was doing. "Okay then~ What pic do you want?" He asked and started stripping his clothes. Nightmare who wasn't looking, turned to see what Killer was doing and blushed when he saw Killer's cloth-less ass out in the open.

"Dick? Cunt? Tits? I can even do feet. What is it that you want, mister?" Killer asked, holding his phone up as if to take a selfie. Nightmare practically froze as he saw his curves and wide hips.

He'd hate to admit it but... It was really making his "friend" perk up even when Killer had NOTHING summoned (yet). Killer was practically giggling as stared at Nightmare with a seductive look. "Or do you want a 360° look of the real thing, hmmp?~" He asked, making his way towards his "excited" boss.

He sat on his lap and wrapped his arms around his neck. "C'mon! Wouldn't want your meal to be cold." He said fully as he licked his nose. Nightmare turned even Cyan-er and his pants glowed like a light house. Killer practically grinded on him, summoning his female ecto-body to better feel Nightmare's boner. "Ugh...Boss, your so hard... I wanna feel it...~" He groaned out and Nightmare immediately snapped.

He immediately slammed Killer on his desk, spreading all the important paper out. Killer gasped at his reaction and immediately was cut off by Nightmare kissing him aggressively. Killer kissed back, moaning into the passionate action. The dark skeleton used his legs to spread out Killer's legs and he rubbed his (extremely) hard boner into Killer's wet-ass pussy.

"Mhmm-Aah~ N-nihhtmare!" Killer moaned out from all the pleasure and Nightmare smirked at how Killer was desperate and dripping for him. He was about to remove his shorts when-

KNOCK! KNOCK!

Nightmare woke up from his WILD dream and immediately looked around. He had his face on his hand and he was surrounded by his usual paperwork. His face turned cyan after realizing what he had dreamt about and felt shame as he was made aware of his... Lewd desires.

He began having flashbacks of those passionate moments and tried to forget about it when he heard a ding from his phone. Annoyed, he turned to check and when he saw it was a text from Killer, he immediately read what it was.

Kills: Hey Boss!~ Kinda need some help... 🥲

Boss: Why? What is the problem?

Kills: Just come here...pls... 😓🙏🙏🙏

Boss: Come to where? Is it important or is it something stupid?

Kills: It's about...uhm... Just come to my room...

Boss: Okay? I'll be right there.

Nightmare looked up from his phone and shrugged it off, maybe this was important? But it felt kind of weird... Going to his room right after he had THAT dream about him...

Trying to shut his thoughts, he stood up and used his powers to teleport in front of Killer's room since it saves time and energy. But when he reached his room, something felt "Off". From what his abilities told him, there was a mix of unexplained extremely "happy" yet disgust, desperation, and hurting in Killer's room? He lightly knocked on the wood and immediately, he heard Killer's shaky voice answer, "C-come in...".

The dark skeleton walked in and was quickly hit by a weird scent that made him feel a bit "drunk". He looked around in Killer's room and noticed it was a bit dim-lighted.

He finally laid eyes upon Killer who was standing awkwardly by the bed and noticed a few key details... He was only wearing a black turtle-neck sweater and his cheek bones and joints were all red. Nightmare's cheeks were dusted a shade of cyan when he realized that Killer had no pants or underwear on but he had summoned a female ecto-body. He could lightly hear shaky breaths coming from the short skeleton and suddenly, a realization hit him.

"...Are you in...heat?" Nightmare asked calmly as his cheeks light up some more. Killer looked at him desperately and said "Y-yeah and... I can't believe I'm saying this to my boss but- Can you help me, Night?..." Pleading him with hand gestures.

Nightmare gulped, that scene of Killer begging him combined with his memory of Killer's desperation in his Dreams. He couldn't explain it but, he wanted to help.

"I-it's okay if don't w-want to boss... I'm just a disgusting and needy slut anyways..." Killer muttered, looking away as his legs were shaking lightly. Nightmare raised a nonexistent eyebrow and walked towards him. "Are you sure you want ME to help you?" He asked, trying to see if Killer was truly thinking about his decisions. Killer nodded as he looked up to Nightmare and placed his hand on his chest...

He then chuckled and whispered into Killer's none existent ear, "Heh, then act like the disgusting and needy slut you say you are.".

(OKAY HELP-)

Killer gasped at that and gulped. He placed his hands onto Nightmare's shorts before slowly getting down on his knees. Nightmare hummed at that before smirking as he used his tenticles to lock the door. Killer slowly pulled down Nightmare's shorts and boxers and immediately, his cock sprang out almost hitting Killer on the face.

The heated skeleton practically drooled when he saw the length.

A/N: Oke- I give up 💀
