My Best Nightmare?

Result

That morning when Blue woke up, he felt relieved, and more relaxed... It was nice until he moved and felt a wetness underneath him.
"And...fuck..."
Blue stood up, the bad result of his...interesting dream appeared to have left a mess all over his bed sheets...and underwear. He sighed.
"Well I guess I gotta change now"
Walking over to his dresser he took out some boxers and shorts. As he did he looked around his room, seeing what he took out of his dream from last night.
"Hm I don't see anything... So I wonder what I-... Uh oh..."
Just as Blue took his boxers off, he felt warm sticky liquid slowly slid down his thighs. Slowly looking down Blue saw an alarming amount of cum starting to slide out of him.
"We definitely were busy last night but I wasn't expecting...this... This morning..."
Wobbling himself over to the bathroom, Blue went to clean himself up... Or at least try to. After cleaning himself up the best he could he put on his shorts and sat back down on his bed.
"I should probably take something..."
Blue grabbed his phone to look up what he should be taking in this scenario.
"I should probably look up what to take before going to get some..."
Blue was going to look something up when he stopped.
"...Or...maybe..."
He put a hand on his stomach
"I already have one of the things I wanted... What if I could have more..."
Blue thought to himself, but immediately shooting down the idea in his head.
"No...that wouldn't be fair to Nightmare...and besides this probably couldn't have gotten me pregnant anyways... So it's just a precaution..."
Blue took a few deep breath's
"But still despite that I'll have to tell Nightmare, it's a good idea to tell him and again it wouldn't be fair not to..."
Looking back down at his phone Blue started to look up if he could take some pill and what it was called as he put on Nightmare's hoodie and left his room. He went out to the kitchen to see Dream and Ink, standing there obviously waiting for him.
"Oh hey guys, is there something up?"
"No not really, but we just need to talk to you about something..."
Dream said, appearing a tad bit uncomfortable. That confused Blue a little, but he decided to brush it off.
"Ok, what is it?"
"Palette said he heard you...making noises in the middle of the night..."
Ink said, sounding just as uncomfortable as Dream did. Blue was gonna ask what kind of noises when he remembered what happened in his dream. He blushed and started to apologize.
"I-I'm sorry guys, I didn't think-"
"It's not a big deal, the only reason he heard you was because he walked past your room. And besides you did a pretty good job at being quiet."
Ink added, pretty nonchalantly making Blue blush more. Ink noticed and chuckled.
"What? I'm not wrong, well then again anyone's pretty quiet compared to Dream.-"
"INK!"
Even though Blue was embarrassed he couldn't help but laugh along with Ink at Dream's little outburst.
"But really I am right Dreamy, you gotta admit it some day."
"Ink stop!- that's not the point!"
Blue and Ink both finished laughing at Dream's request.
"Ok now that you two got your chuckles in. Blue, you'll try not to bring your 'friend' around anymore when Palette's here right?"
Blue didn't know what Dream was talking about until he remembered that he told Dream that he had a mysterious...'friend'... Blue tried to think of a better way to spin this, to make it at least sound better than it did. Because even to him it sounded pretty bad...
"I'll try not to, but I've actually been wanting to tell you something about me and my 'friend' for a little while now."
"Ok, go on?"
Dream asked, making Blue sigh and come clean...well not fully just a little.
"Well I wanted to wait till I was sure... But me and this 'friend' are now...official..."
Both Dream and Ink stopped
"Like official, official? Like not like that thing that happened with Lust after Red, kind of official?"
Dream asked, his face starting to light up
"Ya...I really think so..."
Blue smiled hearing Dream squeal and pull Blue into a tight hug.
"I'm so happy for you! I really thought this was something else, but now I'm so happy for you!"
Blue giggled returning the hug
"Thank you Dream!"
"It's not just him, I'm happy for you to!"
Ink also screamed enthusiastically. After another moment Dream let go of Blue.
"I don't want to hurt you if you're soar, so I-"
"I get it Dream and thanks"
Blue was still giggling, but felt a little more awkward. Dream realized and apologized.
"S-Sorry you know how I can get when I'm excited."
"Blissfully unaware, like Ink?"
Both Dream and Blue chuckled and Ink just shrugged.
"What? I can't help it?"
Ink added making the other two only laugh more.
"Haha, I suppose you can't Inky. But I've never minded."
Dream reassured, planting a small kiss on Ink's cheek.
"But anyways, Blue you know we're both happy for you but you get what we're trying to say right?"
Dream asked, Blue nodded
"I do...and again I'm sorry we had to have this talk in the first place, I should've known better."
"Again it's ok. Now come on, I promise Palette that we'd go watch a movie with him. So you wouldn't-"
"No I wouldn't mind Dream"
"Thanks..."
"Don't mention it, now where's my little adorable nephew?"
After that the three walked off to go find Palette. Blue felt relieved to have told his friends that he was seeing someone, but was still a little scared that they would soon some how found out who...
A little while before this was going on, Nightmare also woke up and similarly to Blue felt relieved until he felt the wetness on his bed.
"Damnit, I'm gonna have to clean that later-"
And saw the newly formed boner in his boxers
"Guh...fuck"
Touching it through his boxers he felt that maybe it wasn't so new, as he groaned feeling how sensitive it was. Knowing that he couldn't leave like this, he threw the rest of the covers to the side, and pulled off his already jizz stained undergarments. Nightmare let out a hiss feeling cold air hit his very erect member, covered in precum.
"Damnit... This might be worse than I thought..."
Gently grabbing ahold of his hard shaft he let out a shakey groan. Before he started he looked over at the door.
"Good...locked..."
After checking to see that the door was locked, Nightmare started to move his hand. Again he let out a shackey moan. He slapped a hand over his mouth and started to move his hand faster.
"Mm...F-Fuck..."
Nightmare thought to himself, starting speed up his pumps when he stopped getting an idea.
"Let me try..."
Nightmare changed into his corrupted form, letting one of his tentacles slide over to his member and wrap tightly around it. He let out a loud moan and smirking.
"T-This- Ah~ Is much better~"
Nightmare let his tentacle jerk him off as he just moaned. As this went on he started to moan out Blue's name, remembering what happened the night before and how wonderfully it was.
"Hah~ B-Blue!~"
He realized how loud he was being so again he covered his mouth. Soon he felt his orgasm start to creep up until his member twitch and he cam.
"Gah! Fuck!- ha~..."
Nightmare panted, and deciding that he's been in his room long enough especially after the activity he just finished up with, he stood up, put on some fresh clothes, and left, changing into his passive form as he did. When he got to the kitchen though, he was met with awkward stares. Confused he asked-
"What is it?"
No one said anything for about a minute so at first Nightmare just decided to shrug it off until Horror randomly asked.
"We all just heard you jack'n off boss..."
Nightmare almost dropped his mug he was so surprised and embarrassed. Snapping to face his team he sputtered.
"I-I-I was doing nothing o-of the sort!"
"Ok...then you were watching porn?.."
By now the others were starting to laugh as Killer now joined in on questioning Nightmare. Nightmare's blush intensified.
"No!"
"Ok, well it has to be one and either way it's gonna be embarrassing."
Nightmare was going to object when he realized that Killer was right, it wasn't like he could play it off now. So he sighed, knowing that if he wasn't honest, then he would just be pestered all day until he came clean.
"I...had an...'interesting' dream, and when I woke up I realized that dream gave me a 'p-problem'..."
Everyone in the room other than Nightmare started to laugh, only making the king blush more. He was only blushing and grumbling to himself until he heard something that he couldn't ignore.
"S-So you were the one that was moaning Blue's name in your sleep?"
Dust managed to say between chuckles and wheezes.
"W-What? You- You heard me say his name! In my sleep no less!?"
"Uh ya?"
Killer said, a little confused as to why Nightmare was yelling and upset.
"You know it isn't a big deal right Nightmare?"
Cross asked, walking over to Nightmare
"So that being said is there something else going on?"
Cross again questioned. Nightmare didn't know how to respond or if he should. Then he thought about Blue's advice from before.
"It went well last time, it should go well now..."
Nightmare looked up at Cross, and the others standing behind him. Then he pictured them being his brother and the creator.
"But if Blue were in my position, I would in no way expect the full truth to come out of him. The difference from there and here mine as well be astronomical... So with me thinking that..."
Nightmare let out a small sigh
"I mine as well try and be honest... But let's just say that first and for most that this will be a much shorter and more understandable story than the last truth..."
"Ok go on, I'm not sure about them but I'm at least listening."
Cross said, still smiling. Nightmare knew that similar to the last time he had to be honest, and the fact that Cross was only trying to appear understanding to make the honest part easier for him.
"As you're aware I'm able to travel between dreams when I am asleep. One day I felt a strong negativity from some where. So I went to check it out and it appeared to be coming from Blue."
"Odd...I wonder what made him feel like that way..."
"Jealousy, of his friends, of my brother... So since it was my brother, I understood some of the things he was feeling...and as we got to talking we bonded and after that day I couldn't help but keep going back. So for the past month or maybe more I've quit counting, I've been going to Blue and hanging out with him."
"And as for what happened last night..."
Nightmare again blushed and mumbled
"That was our first..."
Cross chuckled
"Aw that's cute. Was that your first kiss to?~"
"Yes..."
Cross looked surprised
"O-Oh I was kidding..."
"Well that's the truth..."
"S-Still, still, it's good that you're seeing some one. Even if it's actually in your head, it's good that it's real in that way. Speaking of which you should bring him around, or go out and actually see each other."
Nightmare thought about it and smiled
"That would be nice... Especially now that I know at least one of my boys doesn't mind."
"W-We don't either, but is that r-really the big thing boss?"
Killer said, as him and the others stifled some giggles.
"Yes..."
Nightmare grumbled out as he heard the uproar of laughter that he was expecting. Cross started to curse them off when Nightmare stopped him.
"It's ok, despite their laughter I can recognize that they are happy for me."
Cross rolled his eyes
"I know but they can be so in mature sometimes."
"I know, but that's the only reason I keep them around."
Nightmare hummed getting himself some coffee.
"I guess..."
Cross barley agreed. Nightmare only chuckled a little after that before sitting down and starting to drink his drink. As he did and as the laughter died down, his team did actually start to ask question. With a reasonable amount of laughter Nightmare got through it, and then wondered what Blue will think when he hears about this.
