"Hi Killer! Where is Error's room, he told me he needed my help with something." Ink smiled awkwardly. Killer spun him around, pointing down the hall.

"It's the vet last one at the end of that hallway. It's black with blue strings wrapped around it, you can't miss it!" Killer instructed. He put a condom in Ink's hand, making him confused.

"Uhh, what's this?" Ink asked, looking at the condom closely.

"It's really important! Give it to him and he'll know what to do." Killer smiled, giving Ink a little push to begin walking.

"Oh, thank you so much!" Ink smiled before running to Error's room.

"Ah, new company! His little ass is getting destroyed today!" Killer laughed to himself. He heard some noises coming from Nightmare's room. He stood at the dark purple room, his hand hovering over the golden hued doorknob. The cyan crescent painted onto the black circle on door seemed to be judging Killer. He was able to brush it off, grabbing the doorknob. He silently peeled into Nightmare's room. Nightmare had changed from his tank and pajama pants into a cuter outfit. Killer knew it was wrong as he saw Nightmare, his boss, jacking off, but he couldn't stop himself from watching anyways. Nightmare looked around the room, not realizing Killer peeking in through the crack in his door. What Killer heard next made him horny, confused, scared, and flattered all at once.

"Ahh!~ K-Killer!~" Nightmare moaned. Did he masturbate to Killer?! Killer felt his pants tighten up. He leaned in more to look closer. Everything was perfect, picture perfect. Nightmare's hair was down, which was not at all common. The lavender, over sized sweater hung over his shoulder, showing the black blotch of skin left behind by Corrupt possessing him. Ever since the first time, Nightmare had turned into a new person. It's been barely a month since he turned back, more or less, he had shown to have some blotches of skin left, some turned into crescent emblems onto his skin, others disappeared as if they never existed. Killer wondered if the blotch on the back of his left thigh was still there. 

"Ahhh!~" Nightmare orgasmed as his cyan seed shot form his member. Despite coming, Nightmare was still hard.

"Gah!" Killer fell from leaning in too much. Nightmare was obviously surprised and pulled down his large sweater, covering as much as he could. What Killer couldn't help but notice was the pinkish-purple glow coming from underneath his sweater. He was in heat!

"What do you think you were doing?! Watching me?!" Nightmare blushed, lifting Killer with his summoned tentacles. The door shut by impact.

"Hey! I fell! Lemme go!" Killer struggled against the slimy grip. Nightmare squeezed him, getting an unexpected reaction. "Ahh!~"

Nightmare blushed a bright purple. He felt hella turned on by that, but he wasn't going to admit it. Not wanting to trigger his heat much more, he shoved a tentacle down his throat to muffle the moans. Killer moaned again, sucking on the tentacle. Heat taking over his body, Nightmare flopped on his back, moaning. Killer sucked harder until the tentacle was pulled out of his mouth. A black fluid remained on the insides of his mouth. It tasting similar to the smaller's seed, Killer swallowed it. Nightmare dropped Killer onto the floor, laying his bed, pantsless. He was wearing stockings, but his upper thighs were open. Killer climbed onto the bed and between the smaller's legs.

"Eep!" Nightmare squeaked, his legs getting lifted onto Killer's shoulders. Nightmare knew why he did this. That way, Nightmare could stare Killer I'm the eye as he sucked him off. As his cum filled his mouth. So he could watch as he drank it all up.  Killer smirked before taking Nightmare's member into his mouth. While the feared man wasn't exactly blessed with a long dick, Killer still gagged when deepthroating him. 

"Hmmm~" Killer hummed, smirking onto Nightmare's dick.

"Ahhh!~" he moaned, coming into the taller's mouth. Killer happily swallowed all of the cyan cum.

"Hmm~ You still taste delicious~" Killer licked his lips, making the smaller blushed and hide his face with his oversized sleeves. Killer took Nightmare's arms, pinning them above his head and out of the way, "Don't hide yourself, Nighty~ I want to see you~"

With that, Killer's dick penetrated Nightmare's entrance.

"Ahhhh!" Nightmare screamed in pain. Killer smirked, knowing how much Nightmare secretly loved it. He smirked as he began to thrust at a quick pace, not letting Nightmare adjust. He had an idea on how to make Killer think twice about trying to make Nightmare suffer. He shoved a tentacle up Killer's entrance as he thrusted.

"H-hey! Don't you d-dare abuse your m-magic!" Killer held in his moans , thrusting even faster then before. The tentacle began to thrust in and out of Killer as he did so with Nightmare. 

"Ahh!~ Damn!~ Your ass is so tight!~" Nightmare moaned, laying back. He was dazed by all the pleasure he felt at once. Nightmare shoved another tentacle into Killer, making him moan. He had a third tentacle feel around his body as a fourth one was shoved down his throat. Killer sucked the tentacle and began to thrust at inhuman speeds, making Nightmare's walls bleed.

"Is this funny now?!" Killer growled, pushing the tentacle out of his mouth with his tongue.

"H-hey! St-stop that! K-Killer! That hurts!" Nightmare begged, feeling harsh pain from Killer's actions.

"Stop what? Stop this?~" Killer found a way to go even faster, making Nightmare hurt even more.

"Stop! I-I don't like this!" Nightmare stopped using the tentacles to make Killer learn a lesson and began to go try to get him off. Killer grabbed Nightmare by the top of his hair, pulling it harshly. The tentacles were unsummoned as Nightmare couldn't focus at all on what to make them do. Killer began to slow down, grabbing his dick. Killer jack him off as he thrusted at a quick pace.

"Good boy~ That's a really good boy~" Killer smirked, knowing about Nightmare's little kink.

"Oh!~" Night couldn't help but moan at his voice praising him. He returned Killer's famous smirk as he shoved a newly summoned tentacle into Killer. The taller moaned, going faster. Nightmare began to thrust the tentacle in and out of Killer, going at a faster pace. Not letting a tentacle in his ass out thrust him, Killer began going at that same, inhuman speed. The tentacle was unsommoned as Killer pounded into the smaller a last time, filling him with his sticky seed. 

"Ahhh!~" Nightmare orgasmed again as his cyan cum covered his sweater and Killer's shirt.

"How did that take care of your little heated problem, Princess?~"  Killer pulled out harshly, making Nightmare moan again.

"T-thank you for helping me..." Nightmare laid in his bed, not wanting to move for another hour or so. 

"Thank you, who?~" Killer bit his bottom lip. Nightmare blushed even more, knowing what Killer wanted. He muttered something. "What was that?~"

"Thank you, D-Daddy..." Nightmare muttered, covering his face with a pillow.

"That's a good boy~ A very good boy, that's what you are!~" Killer pet Night's head, flopping down next to him. Killer pulled a blanket over them, ready for a mid-afternoon nap. "And Nighty?"

"Yes, K-Kills?" Nightmare brought the pillow from his blushing face and put it under his head.

"Fuck me with those tentacles and I will wreck your ass." Killer threatened.

"That's the plan!~" Nightmare grinned before falling sleep.
