Work Text:
Peter opened his eyes in the morning and immediately shut them, burying his face in his pillow. He woke up to the sound of Kurt's alarm so he couldn't have slept in, so why was it so bright? He opened one eye and saw the curtains were closed. Then, Peter noticed he wasn't in his bed. He pushed himself up and looked down at the sheets, they were Kurt's. He also caught sight of his arms while he inspected the bedding and yelped. Peter was blue. He was blue and furry and had only two fingers and a thumb and thick black nails.
———————————————————
The noise woke Kurt up, somehow his alarm didn't just a moment before. He opened his eyes and saw… himself? Kurt sat up and blinked, noticing the room was a lot darker than it usually was. But that made no sense, he had night vision as part of his mutation. He looked down at his body and saw human skin. Kurt held out his arms and flexed his hands a bit before doing the same with his legs. He took account of the fact he didn't have a tail.
“How are you being so calm about this?” Peter, at least Kurt assumed it was Peter since he was in the older boy's body, asked.
“It vill not help to panic,” Kurt said.
“God, it's weird hearing a German accent come out of my body.” Peter stood up and immediately tripped, not used to Kurt's feet.
Kurt chuckled a bit behind his – Peter's – hand. “Valk on your toes,” he told the speedster.
Peter held onto the nightstand and lifted himself up again, this time standing on his toes like Kurt told him to. He got a few steps farther before he fell. Only this time he had nothing to hold on to, so he fell and caught himself with his hands. Peter looked embarrassed for a moment, before his expression changed to one of surprise.
“Is this why you walk on your hands sometimes?” Peter asked. He crawled his hands back a bit to sit like a cat, mimicking the way he's seen Kurt sit many times before.
"Nein, mein Freund," Kurt said. It was a bit jarring to hear Peter's voice speaking German. “I am able to keep my balance.”
“That's not what I meant. I mean I can't do this,” he gestured to himself. “This whole flexibility thing. Humanoid people can't do that.”
Kurt tipped his head to the side. “Vhat do you mean?” He slid off the bed and got on his hands. “Oh, you are right. Zhat is bad,” he said, sitting back up on his knees. “Vhy have I not known zhat?”
“Dunno. Probably because you're used to it? Hey, how does your tail work?” Peter asked. He turned his head to look at the tail lying limp behind him.
“It is just muscles. I have never not had a tail, so I have not had to learn how to use it.”
Kurt stood up and balanced himself before trying to walk. He was much more successful than Peter had been, seeing how he was still standing and the older boy was currently confined to the floor.
“Ve should talk to ze Professor,” Kurt said, offering Peter a hand up. Peter tried flattening his feet again, but he fell. “On your toes, Liebling.” Peter stood back up on his toes. “Lift your tail for balance,” Kurt instructed. The older boy focused on picking up his tail. It helped a bit.
“I am so glad you shower at night,” Peter said. “I don't think I could take care of your fur.”
“Oh, I did not sink of zhat,” Kurt blushed.
Peter saw he was uncomfortable and backpedaled. “You don't have to shower, I'm not a sweaty person. You'll be fine for today,” he said quickly.
Kurt sighed, “Good.”
“How are you not constantly overheating?” Peter asked. “This,” he gestured to the fur, “is all so thick.”
“I pant,” Kurt said bluntly.
“You're joking,” Peter said.
“Nein,” he shook his head.
Peter bounced on his toes a few times, getting used to standing like Kurt. “How am I supposed to get dressed?” Peter asked. “With the tail and everything.”
“For me, ze tail is just anozher limb. You might need to pick it up, zhough. Vear a button-up.”
“Why? This is comfy,” Peter said, holding the oversized shirt.
“Because you can not vear pajamas to school and button-ups are easier on ze fur. You vill be uncomfortable if you vear a t-shirt.”
“You wear my t-shirts all the time.”
“Fine. Do vhat you vant. I am just varning you zhat it vill be uncomfortable.”
Peter rolled his eyes and walked over to his dresser. He picked up one of his band shirts he knows Kurt likes and took off his shirt to put it on. “Oh, ew, God no. You were right,” Peter complained, immediately taking the shirt off.
“Told you,” Kurt said, taking the shirt and putting it on himself. “My button-ups are in ze closet.”
Peter grumbled while walking over to the closet. He held onto the dresser while he went, trying not to trip again. Kurt pulled the shirt over his head and looked down, suddenly stuck. He worried it would be an invasion of Peter's privacy to change his bottoms. He watched Peter button the shirt and turn around.
“...What do we do now?” Peter asked, seemingly stuck in the same problem as Kurt.
“Close our eyes?” Kurt said, half joking.
Peter seemed to consider it. “No, that doesn't work. I can't use your tail. Just wear the same thing as last night,” he told Kurt.
“Ew… Is zhat vhat you do?” Kurt scrunched up his nose.
“No, but this is hopefully only for today. It'll be fine.”
“Vhat if it isn't only for today?” Kurt asked.
The older boy shrugged. “Then we deal with it tonight. And I'll also learn how to clean your fur. We're adults-ish, why can't we be mature about this?”
“‘Adults-ish’,” he laughed.
“We're only barely eighteen, Blue,” Peter said. “Hence, ‘adults-ish’.”
“If you are saying ve can be mature, vhy don't ve start now?” Kurt asked. “I do not necessarily vant to vear your clothes from last night vithout at least a shower.”
“Because I don't want to be mature about it. I'm trying to push that off as far as I reasonably can,” Peter complained.
“Take your pants off and put somezhing else on,” Kurt ordered him. “Now.”
Peter tried so hard to not make a dirty joke. “Fine, mom,” he opted to say instead.
Kurt ignored him. He opened Peter's drawer and looked for a pair of underwear and jeans. He started second guessing his decision, but he saw Peter already changing with his eyes closed and decided he had to do it with him. Kurt closed his eyes and changed.
“We got past that,” Peter said. “Now, how do we do school?”
“Give me your schedule,” Kurt said. He pulled his schedule out of his desk and gave it to Peter.
“Why do you still have that? I got rid of mine after I memorized it.”
“In case I needed it,” Kurt answered.
“Do we have to go to class?”
“Yes.”
“Either way we're missing the lesson,” Peter shrugged dismissively. “Even if we go to class, we're in the wrong classes. It would be better for both of us to miss the lessons and get our assignments Monday when everything's normal again.”
“You sink it vill take until Monday?”
“No, but it's Friday so we can't get our work until Monday.”
“We live at ze school, Peter.”
“You think teachers don't take breaks?”
Kurt bit his lip. “Fine, I suppose you are right. Ve should still go to ze Professor.”
“Or, we can have fun,” Peter smiled evilly.
“No, Peter. If ve are doing anything, it is going to our shared class. Ve have Mr. LeBeau togezher for P.E.” Kurt sat down on Peter's bed.
“You're such a buzzkill,” Peter complained, falling onto Kurt's bed. “You made me touch your dick for nothing,” he rolled his eyes.
“Peter!” Kurt shouted at him, embarrassed.
“What? I was getting dressed. It's not like I saw anything.”
“Don't say it like zhat,” Kurt buried his face in his hands. “Ve are going to class.”
“Boo!” Peter whined. “Can I try teleporting?”
“No!” Kurt sat up. “You need to be somevhere open. I don't vant you accidentally killing me.”
There was a loud BAMF and suddenly Peter was on top of him. “It worked!” Peter shouted happily. Kurt fell backwards at the action and was now lying on his back on the bed. Peter sat up on his knees with his hands next to Kurt’s head, caging him in. “I'd kiss you right now, but you look like me so that's kind of weird,” he said.
Kurt rolled his eyes. “You are insufferable.”
Peter laughed and buried his face in Kurt's neck. He nuzzled into him and Kurt wrapped his arms around him. “You are right, I am soft,” Kurt said, starting to pet Peter.
“I can't believe you can't feel your own fur. That's, like, the saddest thing I've ever heard.”
“Your father abandoned you, Peter,” Kurt said.
“Yeah, and you not getting to feel how soft you are is worse,” Peter said, looking up at Kurt.
“You are truly horrible, Liebling,” Kurt sighed.
Peter smiled. “You love me for it.”
