Work Text:

Nightmare was reading underneath the tree as Dream had gone to another tea party in town. Nightmare sighed softly as he took out his peach and began to munch on it as he read on. This book was so interesting. It was a fiction book about magic. Nightmare had a little chuckle at the portrayal of magic. It was so weird to see people using their magic without soul or monster power! Nightmare kept reading and was completely invested in the fact that the human mages could just produce magic out of a stone or staff. Magic wands? What kind of cores did they have? Nightmare wanted to ‘fix’ this lore, so he began to write his own story. He included soul magic and abilities that monsters naturally had depending on their type. Fire elementals had fire magic, skeletons had bone magic and so on and so forth. He was quite invested in his writing that he didn’t realize what time it was. “Oh stars above it’s late! I should be going home now.”

He finished the last sentence as the sun was setting and packed up his things. He placed his hand on the tree and leaned his forehead against it as well. “Goodnight mother. I shall see you tomorrow”. Oh boy did he not know his words were wrong. He took his bag, hoisting it over his shoulder and began the short walk to their cottage. It was a small cottage, two bedrooms, one bathroom, a kitchen, living room and a small storage unit for food when the winter hit. Nightmare knocked off his boots from any dirt and opened the door. He shut the door gently, hanging up his bag on the hook and taking off his coat and boots by the front door. He smelled some stew brewing and knew Dream was hard at work cooking for them. The stew would last for a few days and they could add more to it if needed.

Night tugged on the collar of his shirt. It was unusually hot in the house. He opened a window and went into the kitchen “Hi Dreamy. How was tea?” Dream beamed back at him “It was wonderful. I think the villagers are really starting to like you. Your stories are amazing.” Nightmare’s soul fluttered at this. “Oh that’s wonderful to hear!” He beamed while setting the table for dinner and giggled “I’m so glad they like my writing. I started the next book today!” Dream smiled as he brought over a large bowl of stew and served the two of them “Oh? How’s that going?” Before Dream sat down he shut the window and lit the fire. He wanted to preserve heat as it was going to get cold tonight. The two began to eat their food and Nightmare noticed the increase in heat. He was slightly sweating by now and Dream noticed. “Are you okay Nighty? You are sweating and look pale! Are you sick- do you have a fever?” Dream fretted over the other feeling the top of his skull. “You seem warm!”

Nightmare nodded “I thought it was the house! I must be coming down with something. I think it’s best if I go to bed.” Dream nodded and put the stew in the cooler “Go on now shoo! Shower and bed!” Nightmare chuckled “I’m supposed to be the older brother here.” and shambled off to take a shower. He took his clothes off, setting them in a basket to be washed the next day and grabbed his robe for sleeping. He placed the robe and slippers next to the shower and got in. He turned the knob and let the cool water wash down his body. It slightly helped to alleviate the heated feelings he had, but not by much. They just kept getting worse. He finally gave up on the shower and shut the water off. At this point the entire room seemed like it was on fire and he groaned. He dried off, hung his towel up, put on this robe and slid on his slippers. He weakly opened the door and walked down the hallway and made it to his room. He wretched open the two windows and gasped in relief at the cool breeze. “Oh I hate being sick.”
Nightmare leaned against the cool glass of the window for a bit and finally decided to draw the curtains, tying them shut so no one could look in while leaving the windows open. He took off his slippers and laid down, drifting off into slumber. About several hours later he was woken up by a strange smell. He smelled oddly like- apples? Wow he smelled amazing. But god why did he feel so hot? He grunted and took some sleeping pills and passed out for the night. By the next morning he was so hot his sweat had soaked through the sheets. Dream was so enticed by the smell that he knew exactly what was going on. Dream walked into the room and sighed “Nighty, it’s time.”

Nightmare weakly whimpered and mumbled “Huh? Time for what?” Dream shut the door and locked it behind him. He then shut the windows and walked towards the bed. He felt so bad for his brother. He sat down gently next to him and pulled him into his lap and pet his skull cooing softly “You are all grown up. It’s your first heat. I had mine a few years ago, earlier than yours, which was very unexpected. I had some help from a friend, but you need help to get rid of it. Let me help you feel good. Please brother?” Nightmare looked a bit terrified at this news and squirmed a bit in Dream’s lap, but Dream held him firmly. “Nightmare. If you don’t relieve yourself now you will burn up! Please let me help you. It won’t hurt. I promise.” Nightmare sniffled softly and hesitated.

Dream cooed softly “Nighty, do you trust me?” Nightmare nodded softly “Yes…” he croaked out. Dream purred and gently undid the robe around the other and laid him on the bed and slowly took off his nightshirt and shorts. Dream kicked off his slippers and crawled on top of Nightmare so that he was sitting on his hips “Have you ever summoned your body before?” Nightmare shook his head “No brother” Dream smiled in response “It’s okay. I want you to focus your magic on the hot feeling and let it take its course and form whatever it wants okay?” Nightmare nodded and let out a breath allowing his body to form. It was female. He gasped, opening his eyes and blushed brightly “O-oh!” He had small perky breasts and his pussy was soaking wet. “W-what is this feeling?”

Dream cooed “You are horny brother. And I’ll fix that.” Dream in response formed his own body, male of course and gently wet his fingers “I’m going to explain everything one step at a time okay brother?” When Nightmare nodded Dream perked up “Oh! Yes, I almost forgot, give me a safe word. So if something hurts I can stop and make you feel better okay?” Nightmare thought about it, but it was extremely difficult as he was very hot and needy. He croaked out “Marigold” and Dream nodded “Good boy. Now, I’m going to gently insert one finger into you okay?” Nightmare nodded and Dream slowly pushed his finger in. Nightmare gasped in pleasure, his body shaking and squirming on the bed as he let out a low moan. He was flushed purple while Dream was flushed gold.

Nightmare let out a passionate sound, as Dream gently moved the finger in and out of him trying to stretch him out as painlessly as possible. Dream knew he had to be extremely careful because it was Nightmare's first time. Dream whispered softly " Okay, I'm going to insert a second finger now. Are you ready?" Nightmare nodded eagerly, his entire body craving more pleasure as dream gently inserted the second finger.

Nightmare arched his back in pleasure, his toes curling at the feeling of the finger scissoring inside of him. It felt so good! Nothing he had ever experienced ever before and he wanted more and more and more. Dream smirked knowing that he would be the only one to make Nightmare feel this way. He would be Nightmare's first and no one else would ever give him such an experience and that made him so possessive. Dream gently took the fingers out of Nightmare and crooned " Okay, I'm now going to eat you out and I promise it'll feel amazing."

Nightmare felt so dazed and all he could do was just nod in agreement. Dream purred as he lowered his face and gently licked the other. Nightmare let out a high-pitched squeal because it felt so cool and comforting after all the other hot feelings he had been feeling all night. Dream loved the taste of Nightmare. God his brother tasted so good! Dream knew that after this moment he wouldn't let anyone else have his brother, only he could. He would make sure that nobody would ever take his Nighty from him again.

Dream spread Nightmare's lips and delved deep into him, lapping up every excess dripping droplet that he could. He groaned into the other as Nightmare was moaning in pleasure. Dream stopped and pulled out his saliva and Nightmare's juices dripping down his face. He licked them up while Nightmare looked a little embarrassed.

Dream knew it was time. "Brother I have prepared you and you are now ready. Do you trust me?" Nightmare's eyes went wide and he connected the dots putting two and two together. He nodded eagerly and blurted out, "I've never felt this good before. Please make me feel good, Dreamy please!" He almost covered his mouth at the end of the statement but dream gently held his hands and softly smiled, "I know I did and I'm going to make you remember this night forever in such a good way that no one else will ever give you the same pleasure. Only me. You're mine. Do you understand?"

Nightmare nodded eagerly and Dream liked himself up and kissed Nightmare. "Mine~" he whispered and with that word, he thrusted into the other gently claiming him. He gasped at the same exact time as his brother did and both of them let out a low moan. "God Nighty, You've been hiding and leaving me out about how good you feel! You are so tight~ I'm so glad I was your first!"

Nightmare gasped and moaned weakly begging for more "Please please please I need more!" He moaned sweetly as Dream thrusted in and out of the other. Dream gasped as he kept going knowing that he had to make every single second count. He thrusted faster and faster until Nightmare gasped out "I'm close! Please! Let me cum brother!"

At those words, Dream turned absolutely feral, lifting the other's legs and letting him wrap around his waist for maximum pleasure as he thrusted ferally and growled out "Cum." Nightmare needed no other invitation than that and came hard around the other. He was gushing everywhere and Dream thrusted one last time before letting out a gasp and cumming into the other. Both twins were left absolutely breathless.

Nightmare Was just extremely glad that the heat had seemed to die down. Dream purred and pulled out spooning around the other and muttered "Go to sleep brother. I will clean you up tomorrow and we will both get after care." Nightmare nodded and drifted off to sleep and Dream was extremely grateful that he was there to help his brother. He wrapped them both gently in a blanket and knew they would have a lot of laundry to do tomorrow.

The next morning Dream woke up first and he began the cleaning process. He knew that Nightmare would be sore, especially because it was his first time and he was still in heat. He would probably have to help the other a little later. Dream kissed Nightmare's forehead, and then got up first washing his legs and then he grabbed all the clothes and the blankets. Nightmare. Didn't mind because he was still pretty hot so he didn't really seem to comprehend the temperature change when the blanket was taken from him.

Dream started up the load of laundry and then grabbed some cool wash rags and began gently cleaning off nightmares, legs and body. Once Nightmare fully woke up he picked the other up and drew a bath. He set the other down in the bath and then he got in with him. He then began to gently wash the other and massaged his hips, legs, thighs, anything that could have hurt. Nightmare was pretty quiet because he had lost his voice from all the noises he had made last night and Dream didn't mind the silence.

He knew that later on he would definitely have to help his brother and he gently began to explain that the heat will last either 2 to 3 days or depending on how bad it was a whole week, but because it was his first one it would only last about the entire rest of the day. Nightmare groaned at this information because he hated being so hot and needy. He disliked relying on others to help him and he realistically wanted to learn how to pleasure himself in case Dream was out when this happened.

Dream knew this so he had planned a little session after their bath to teach nightmare how to pleasure himself in the male and female form as well as had a switch his ecto body at will. That would definitely come in handy. Dream knew firsthand that depending on the type of heat you could be a top or bottom so he knew he had to teach his brother well.

After the bath dream got out and started preparing some oatmeal and eggs for breakfast. Something light on the stomach that wouldn't cause the other to throw up, especially after the rough night they had. Once he was done cooking, he carried Nightmare out into the dining room and gently sat him down at the table. Dream served him a plate in the two began to eat in a very comfortable silence.

Nightmare was pretty happy with what happened and was not at all upset. He just didn't really have a voice due to how hoarse he was. Once he had eaten the food Dream had made, which has magical healing properties, he was able to speak better. Nightmare smiled " Thank you for helping me last night brother and thank you for the meal, it was wonderful. Do you need any help with the laundry or the dishes? I don't feel sore anymore."

Dream nodded smiling softly "Thank you for your generosity. I would love some help with both of those." Once the two were done eating they both got up and did their dishes respectfully. Nightmare cleaned the rest of the kitchen and made sure to write down what they needed to restock on when they went to the market the next day. Dream went over to the laundry room and threw everything else in the dryer and hung up when needed to be dried on the rack.

Once they were done they decided since the heat had not flared up just yet to clean the rest of the house. They went around dusting, mopping, vacuuming and cleaning any sheets that needed to be changed. Was almost winter time so they were really due for a clean. It also helped Nightmare keep his mind off of what was looming ominously in the distance. It wasn't that he was nervous or scared. It's just he really didn't like having this heat. It was just so stupid and he didn't understand it. He would definitely have to research more information on it later when he went back to the library.

Once they were done cleaning he knew it was time because he was starting to get hot again. "Brother, can we prevent this from happening by dealing with it now so it doesn't get as bad as it did?" Dream looked over at him noticing his discomfort and nodded eagerly. " Of course, I didn't know it was already happening again. I thought we'd at least have another two to three hours, but we can deal with it now!" Dream led the other into the bedroom and sat him down.

"Okay I'm going to teach you how to summon both forms okay? First, I want you to focus on what you felt last night. The feminine urges you had, okay?" Nightmare nodded and allowed his body to form. "Oh! I did it!" Dream beamed at him proudly "Good job! I'm really proud of you! Now I want you to focus on having a male body. Think about masculinity and having a dick."

Nightmare giggled at this thought, but it certainly did help paint a specific image in his mind. He was able to easily switch body forms and summon his penis. He was a little surprised at the actual size of his dick. "Wow! I am decently big." Dream was a big smug and pulled his dick out "Not as big as I am but still decently large and above average. Congratulations brother, that's an achievement!" Nightmare huffed but blushed "Is it bad that I still want you to do all the topping?"

Dream shook his head "Not at all brother! Sometimes you're just going to be completely submissive for your entire heat. Mind you these only happen every 6 months, which is really nice. And other times you're just going to want to be completely dominant and top someone else and for each time we could potentially line up our cycles. So that means we would be in heat at the same time making it a lot easier on ourselves. Because of how potent and strong your first heat was, it threw me into an abrupt heat. So our cycles are in sync which is a good thing."

Nightmare nodded squirming as he changed forms and mumbled "Please make me feel good again brother." That triggered the feral instinct that Dream had before and he immediately pushed the other down into the bed and got on top of him and began to kiss him passionately. They made out for quite a while before Dream pulled back saliva connecting their tongues for just a moment before it broke off. Dream gasped panting softly and went down onto the other and began to eat him out again. Even in his frazzled and feral state, he knew he had to prep his partner.

Dream made sure to lovingly stretch the other out as his cock throbbed. He then stared at Nightmare and asked him "Are you ready brother to feel good again?" When Nightmare nodded in agreement Dream wasted no time thrusting into the other. Now that the other was used to him and all stretched out he was able to go all out. He thrusted in and out quickly, and he kissed the other passionately as they fucked. Dream licked down the other chest and purred "You are so adorable and you are all mine." Nightmare gasped in agreement as dream lifted his legs and he wrapped his legs around dreams. Waste in response to this. "I'M YOURS!" Nightmare cried out in pure pleasure as he was railed into the bed.

Dream grunted and kept going until nightmare called out "I'm close please! Please let me cum!" Dream sped up even more if that was even possible and both of them came at the exact same time. Dream was panting and gasping for air as he gently pulled out of the other and cuddled him close. "There we go. All done. Now we don't have to worry about that for another six months. Did you feel good?" Nightmare nodded and sighed softly "It felt amazing brother. I don't think anyone else could make me feel like that!"

Dream flushed at the praise of the other and both of them hobbled to the bathroom and got into the bath. They did the same routine as before. Massaging each other's hips gently comforting each other and making sure they were able to clean themselves up. Once they were done they changed the sheets on the bed. Put them in the wash, cleaning the entire room. Dream opened the windows to air out the smell of the heat scent which would probably send them both back into heat if they didn't. He lit If you candles which ended up smelling like cinnamon; they were a surprise candle so they didn't know what smell they were until you lit them.

Nightmare finished moving everything into the dryer and hanging up whatever needed to be hung on the rack and then got into the bed. He cuddled close to Dream purring softly and said "Thank you brother. You made this experience wonderful. Treated me like a prince, no a king. And I truly am grateful for you being my first and I don't think anyone else could ever make me feel the same way again. Thank you for fucking me senseless. I love you."

Dream smiled and said "You're welcome brother and I love you too." And kissed him to sleep.
