Nightmare X Werewolf Reader X Killer

(This chapter was requested by @SlytherinSnapeDraco . I hope that you enjoy. I totally didn't go back to my phone because wattpad on my computer is being stupid *sarcasm*. Anyways please enjoy this chapter & hopefully it doesn't turn out to be complete dog shit. I feel like I've been slacking hard core on how the chapters turn out & I kinda hate myself for it so yeah feel free to enjoy it.)

It was yet another dark & dreary day in Nightmare's kingdom. Nothing had been really going on around the castle but in the surrounding forrest there had been many sighting's of werewolve's. With all of the sightings, and Nightmare's short temper, he had dragged Killer out to take of the problem. Nightmare had not seen any reason to drag too many of his goons away from the other tasks that he had set for all of them. So both Nightmare & Killer had spent hours taking care of the werewolf infestation. Nightmare & killer had taken care of a majority of the werewolves before they had come across a little caveren deep in the forest. They had both decided to check out the cavern, not wanting to forget any werewolf at all.

After a few moments of searching the cavern they had both heard a cry in the back of the cavern & Nightmare had felt the fear radiating off of whatever the noise was coming from. This had Nightmare kinda intruiged because of how strong the fear was. So he had began to guide Killer to where it was all coming from. Killer had mindlessly followed his boss with a smile on his face, no questions asked. Soon they reached their destination at the back of the the small cavern, finding nothing but a young adult female werewolf who had just came out of her transformation. It was easy to tell she was afraid but it seemed like she had something else besides Nightmare & killer that she had seemed sort of scared of. Though this was no real surprise to the pair, Killer was the first to walk up to the smaller creature & with an enthusiatic tone of voice he had said, "Look boss, their so tiny!"

Nightmare rolled his eyes as he walked himself over to the the other two, staring at the female as he spoke, "Don't tell me you would even dare think about keeping this annoying creature, Killer." Killer smirked a bit before looking at Nightmare. Nightmare looked at the smaller skeleton & glared at him, "What could possibly on your barely functioning mind this time." This caused Killer to laugh a bit before looking back at the werewolf as he spoke ina more excited tone, "Well I was just thinking that maybe we could take our time with this one & enjoy ourselves a bit while we're out. We don't have to kill her right away & we could get a better pleasure status out of it." Nightmare thought about it for a few moments, groaning when he realized that Killer may have a good idea for once. With a sigh & a groan of irritation, Nightmare nodded & told Killer that they could proceed with his idea.

Killer became a little giddy at this, moving closer to the female which caused her to to get nervous & back herself against a wall of a cavern at an attempt to get away from them. She couldn't transform into her werewolf form at the moment because she was in pain after getting a small injury earlier. She had scrapped her leg up on a rock when she was trying to hide in the cavern while still in her werewolf form which caused the cry that led Nightmare & Killer right to her. She was only hiding here to get away from them after watching them kill her a couple of her friends. It doesn't help that all of this was all going on right in the middle of mating season. Killer had kneeled down in front of her & tried to talk to her, "Hello, my name is Killer. What is your name?"

The girl hesitated for moment before speaking, seeing that the one behind Killer was rather irritated at the moment, "My name is Y/N. Y/N L/N." Nightmare leaned on a nearby rock for a moment as Killer & Y/N continued their conversation for a few minutes. It was already irritating him that they had been there for as long as they had been, but now Killer had a plan & was making small talk which would cause them to be there even longer than he really wanted to be. After a few minutes Killer had ushered Nightmare over to them, explaining to Nightmare that the plan had changed just slightly, but that it was okay with the girl that they could go through with it despite her gruesome fate in the end. Nightmare had listened to the changed plan and, though the thought of it irritated him, he agreed with it because he knew it would somehow benefit him in the end. Nightmare then sat next to the others & watched as Killer proceeded with the begining of his plan, begining to sweet talk & seduce the werewolf a bit as if he had known her all his life.

Killer had used his magic to create his entire ectobody & began kissing Y/N, moving his hands slowly to her sides as he even began to massage all of her curves. After a few seconds of kissing her lips, Killer moved down a bit & started kissing her neck & even started to leave a bit of a hickey. This had caused Y/N's heat to kick into overdrive a bit as she had moaned quietly at the feeling. Killer had began to strip them both, leaving a trail of kisses & small hickeys all over her body. This caused Y/N to become even more heated & desperate for his touches. Soon enough Killer had worked himself into her pussy slowly. As he did this Y/N let out a bit of a lewd moan, pushing her hips towards his slowly as her heat made her desperate for him.

As Killer had began slowly thrusting deep into her, Nightmare watched them both closely. With each heated moan that came from the small womans mouth, Nightmare felt himself get very heated. Eventually he had decided that he was willing to join the both of them, moving the small girl just enough to sit beneath her as he formed his ecto cock. As he made it to where he could use his ecto dick he also began rubbing her clit a bit while Killer was still thrusting deep into her pussy. This caused her to moan even more lewdly & desperate like before she had felt Nightmare work his dick into her ass slowly. After a few moments Nightmare had began to start thrusting as well. This had caused a lot of pleasure between all three of them.

As both males had continued thrusting at the same time & pace, Y/N's moans became loud & lewd at the feeling of overwhelming amount of pleasure. This overwhelming pleasure took over all three beings, both males picking up their speed as they felt like they were getting close to their own climaxes while Y/N's holes clenched around their dicks. After a few more moments of deep, quick paced thrusting all three of them had reached their climaxes. They all stayed tangled up with one another for a few moments as they filled Y/N completely with their seed. As Nightmare & killer had pulled out, they watched as their seed had spilled out of her holes. This sight was something that had got both males turned on, it still being clear that she was still desperate for more as is. Nightmare & Killer looked at each other & smirked before they had switched places with one another.

Nightmare leaned over the female & started kissing her as Killer thrusted himself into her ass slowly. As killer did this, Y/N gasped a bit & pulled from Nightmare, moaning softly. As this happened, Nightmare thrusted himself into her pussy causing her moans to become lewd. After a few seconds, both males began their fast paced thrusting once again. This time around the boys got a bit rough with her, Killer biting into her neck as Nightmare began to skillfully massage her breasts. All of this seemed to drive Y/N crazy as she began to moan out their names as she pleaded for them to not stop. This continued for a few minutes before they all reached their climaxes yet again.

As the boys, now both fully satisfied with themselves, pulled out of the small female, they both stared at her & discussed a little more in depth about their plan as they got dressed. They had decided they would keep her alive long enough to find out if she would get pregnant from them. If she did they would keep her alive long enough until they could release the pups into the wild & allow Horror to have his own little killing spree with them later on & would kill her once the pups were old enough. If she doesn't get pregnant from them then they wil kill her on the spot, no questions asked. They both seemed to see this as fair to her. They both then helped to make sure that she got dressed & killer then picked her up bridal style with a wide grin plastered on his face. They then teleported back to Nightmare's castle & put her in a spare room before going about their day, doing their usual activities until the end of the day.
