a bird, a bird, and a octopus (swad, Ds, and og nightmare) <3

Quick note before we begin, this is indeed a lemon so if you are uncomfortable with lemons than please do not read as I don't want to make anyone uncomfortable! Now that this is out of the way this chapter was requested by a noble person, GhamzehPmd ! I hope you are able to enjoy my writing-! And I apologize if I take a bit too long to write! Also I hope you don't mind if I use a certain au, it's basically a god au in where og dream and nightmare are demi gods and swad and Ds are actual gods.

It was raining heavily, nightmare had been under a umbrella trying to keep themselves from getting soaking wet by the pouring rain. It was mid November and so it certainly was cold, the rain wasn't helping any bit with the cold weather that had already been here. Suddenly a strong gust of wind had blown by, violently ripping the poor umbrella out of nightmare's hands so now he was cold and soaking wet in a matter of minutes. Once he got home he threw off his soaked clothes and would slip into something a bit more warm, pajamas, it was pajamas.
Tomorrow had been the annual immortals and mortals peace ceremony, it's basically a big party where representives of each side gather,talk, y'know, do normal party things. Unfortunately Nightmare and his brother are chosen every year to come, dream loves it since he gets to see a certain somebody and the two sneak off every time. Nightmare on the other hand? He hated it, he couldn't stand how obnoxiously loud everyone could be and he generally didn't have anyone to really talk with so he's always alone.
Well sorta, sometimes swad had passed by to annoy him. Despite being a god you'd think that he'd be more mature and such but nope. As for Ds, sometimes affectionately called Nintendo by swad just to annoy, they'd just come over and sit by nightmare, not saying a word to which nightmare had enjoyed. Those two always were invited because they literally had to come.
Eventually it was starting to get closer to that time, nightmare had put on a suit that was black with turquoise metallic markings on the edges of the suit. He had pinned a fake black rose to his suit, it had silver markings that would sometimes glitter in the light if it was at the right angle. Once he had been finished getting ready nightmare had made his way to where the peace ceremony was being held. Dream had been early, like usual.
After a couple of minutes more people arrived, mortals, gods, goddesses, and other demigods and demigoddess's. He hated every single one of them, a lot of these people were quite cocky or obnoxiously loud. Swad was the obnoxiously loud type, but a bit more quieter than the others. Ds was quite strict, but he couldn't really control nightmare's behavior because one, they aren't his father nor mother and two, he's already tried and failed.
This time was a bit odd, he saw swad and Ds huddled up in a corner whispering something. Nightmare had wondered what those two idiots had been planning but little did he know that those two were scheming something big. He had went over to them after they had finished their little scheming plan, coincidentally they were planning on going over to nightmare after. "What were you idiots talking about? ..is it something stupid?" Nightmare had now asked, he wasn't shy and so he found it quite easy to speak like that to swad and Ds despite being just a demigod.
Swad had smirked, slightly glancing at Ds. "Oh, nothing darling!" Nightmare obviously didn't believe this and swad started to walk away, the plan was working. "Hey! You didn't answer my question! Come back here! Swad you idiot!" Ds had followed close behind, swad had lead him and nightmare into a room now locking it. Swad had hugged nightmare, ds doing the same.

(Things get a little...lemon-y from here, just a warning! Lemon AaAaA)
"... what's going on-" Swad had gently stroked the base of nightmare's tentacles. He'd flinch, his face filling with blush. "Darling..this party is boring! Why don't me, Nintendo, and you play? Hm?" Nightmare was unamused that Ds had been convinced to join in Swad's perverted shenanigans. He'd sigh, frowning slightly but he'd nod a bit after. "Fine, just this once and you better use protection." Nightmare had agreed, glaring at swad mainly since Ds was behind him.
Honestly nightmare wasn't quite surprised that swad had pulled something like this but he figured that ds had come up with some of the plan. To nightmare, swad wasn't the brightest lightbulb in a mountain full of lightbulbs. Swad was actually quite smart in actuality but he prefers to have the idiot personality as he found he resembles a dog like that and that since nightmare hated cats he figured that nightmare might like dogs.
Swad had set nightmare down on a desk for the time being and had began to tug at nightmare's shirt only to get his hand slapped. "I can undress myself swad." Nightmare had said, glaring at them. Swad would nod and had let nightmare do just that. Ds had caught himself staring for a long bit of time, swad had only grinned.
"Isn't my darling just beautiful Nintendo?" Swad had smirked, slightly nudging them gently. Once nightmare had finished everyone else got undressed as well too, Ds kept his shirt on though on the off chance that someone could end up barging in. Swad had picked up nightmare, using his wings to shield them and nightmare and Ds did the same with his wings. Slowly swad had entered, nightmare wincing and clenching his fists. It seems they forgot protection and so swad was a bit upset when being practically smacked on the nose. "Protection, get it now." Nightmare was quite stubborn and so this was something that he probably should be stubborn with since he hated children.
Either way swad and Ds had obeyed since swad didn't want nightmare to get angry with him too much and Ds just had common sense to listen. Once they had protection on swad had re-entered, ds now joining as well. It had hurt still and so the two had waited a little while for nightmare to get adjusted, swad was quite excited at the moment. Usually nightmare wouldn't let him touch him as in a simple handshake or hug so this was a huge opportunity for him.
After a bit nightmare had given the two a signal to start moving and they had obeyed, Ds was a bit more careful with nightmare and so the two were both moving at different paces. Nonetheless it had felt good either way, nightmare couldn't even hide it as he had been a bit noisy but luckily music had been playing and so nobody who passed by the room could hear him or even ds. Ds was usually very quiet, so it was sorta odd for nightmare to really hear his voice like this since when he did speak he spoke in a quiet and calm manner.
The two had started to quicken their paces until they were almost in sync. Nightmare had gotten much louder during this and after a while the two began to slow down, nightmare now catching his breathe. Nightmare had released one last time, ds and swad having done the same but they didn't worry too much about nightmare getting pregnant because of protection. Suddenly the door was kicked open by dream who had been trying to find nightmare all this time. "Brother-! OH HOLY STARS-"
Dream covered his eyes and immediately left. Nightmare being unamused was an understatement, he was furious. Immediately he just began to pull his clothes back onto his body. "You will not speak of this Ever got that?" Swad and Ds had nodded, watching as nightmare vanished.

Dream wished un existence on his self at that moment- anyways I hope you enjoyed!
