Ruka was supposed to be back on the U.A. campus grounds in her dorm room by now, but instead she was going to spend the night at the Midoriya residence with Izuku and his mother. Earlier that day, Class 1-A had planned a shopping trip at the Kiyashi Ward Shopping Mall on their day off. Ruka had to get special permission from Principal Nezu to go and had to wear quirk canceling cuffs and be shackled to Izuku. The original plan was to shop together for a few hours then return back to the school and have the quirk canceling cuffs and shackles binding Ruka and Izuku together taken off and they'd go their separate ways for the day. But an unexpected and scary encounter with the League of Villain's leader Tomura Shigaraki had them take a trip to the police station until is was night time. After they were done being interviewed, Ruka couldn't get ahold of Principal Nezu to tell him what had happened and what was going on now. She was stuck, chained to Izuku until they went to school the next day. So Izuku's mother kindly allowed her to spend the night at their place since she didn't really have a choice. Inko unlocked their apartment and she and Izuku stepped inside, Ruka following behind them.
"Thanks so much for letting me stay here for the night." Ruka thanked Izuku's mother Inko who was taking her shoes off near the door.
"Oh it's no problem really, dear. After all, what else are you going to do in this situation?" Inko said as Ruka took off her shoes as well.
"I suppose you're right." Ruka said with a small chuckle.
"Izuku, could you please show Ruka around and prepare a place for her to sleep in your room?" Inko asked her son who just finished removing his shoes.
"Yes Mom. I was already planning on it. Come with me Ruka." Izuku said, gesturing for her to follow him.
"Not like I have much of a choice." Ruka teased, rattling the shackle on her left wrist connecting her to Izuku's right wrist. He began to give Ruka a tour around the apartment then brought her to his room. She giggled at the All Might themed bedroom. There were All Might posters all over the walls and All Might figurines placed neatly on shelves throughout the room. Some of them were limited editions.
"I know, I'm a bit of a nerd." Izuku said with a sheepish grin on his face.
"You are, but I find it kinda charming. You're not afraid to display your passion through your taste in decoration." Ruka said as Izuku blushed slightly. Before he had let her into his room, he was afraid that she was going to find his fanboy nerdy side a bit off-putting and maybe even a little creepy. He was relieved to find out she actually found it kinda charming as she put it.
"I need to go get the spare futon from the storage closet." Izuku said as he headed out of his bedroom. Ruka followed since she was shackled to him. They went to the storage closet in his apartment to get the spare futon then went back to his bedroom. Izuku then set up the futon for Ruka to sleep on next to his bed.
"Hey Izuku I need to use the bathroom." Ruka said.
"Okay. I'll just wait here and go after you're done." Izuku said as he sat on his bed. Ruka held up the shackle on her left wrist.
"I'm literally shackled to you, remember?" Ruka said as Izuku blushed slightly out of embarrassment.
"Oh yeah. I forgot about that." Izuku said as they headed towards the bathroom together. Ruka went inside and Izuku held the door shut from the outside since the door wouldn't close all the way because of the chain. Good thing the chain was as long as it was, otherwise they would both have to be in the bathroom at the same time as one looked away as the other did their business. After Ruka was done, she and Izuku switched places with her holding the door shut for him. They went back to Izuku's room after that.
"I'm going to change into my pajamas now. I can lend you some clothes to sleep in if you want." Izuku said as he grabbed a pair of pajama pants and a night shirt out of his dresser.
"No thanks. I'll just sleep in what I'm wearing." Ruka said as she and turned around to give him some privacy. She smirked as she heard Izuku undress behind her, wondering how long it would take for him to realize the problem with changing clothes in their situation. Izuku took off his jeans and put on his pajama pants. Then he took off his shirt which just slid down the chain by its sleeve. He realized he wouldn't be able to change shirts because of being shackled to Ruka.
"Having trouble?" Ruka asked with a giggle, turning around to see Izuku shirtless and blushing from embarrassment while looking at his shirt hanging from the chain by its sleeve.
"I guess I'll just wear the same shirt to bed." Izuku said as he started to put his shirt from earlier back on as Ruka chuckled. Izuku then went over to his door and closed it, shutting off the lights as well. He then used his phone to make sure he didn't trip as he walked over to the futon, pulled back the blanket and laid down.
"I thought I was gonna sleep on the floor." Ruka said, seeming confused.
"You're my guest. You should get the more comfortable place to sleep." Izuku said as he sat up and gestured to his bed, patting the mattress.
"But it's your bed." Ruka said as Izuku chuckled.
"Don't worry about it. I'll be fine." Izuku said as Ruka sighed. He seemed adamant that she should sleep in his bed and it didn't seem like arguing with him was going to go anywhere.
"Okay, fine. I'll sleep in your bed. Happy?" Ruka said as Izuku grinned widely. She walked over to his bed and peeled back the covers and climbed in. His bed was even more comfortable than her bed back at the U.A. dorms.
"Just promise you won't yank me out of bed with the chain, okay?" Ruka said jokingly as Izuku chuckled.
"I'll try not to." Izuku answered as he adjusted himself to get more comfortable in the futon.
"Night Izuku." Ruka said as a big yawn followed, making Izuku yawn as well.
"Good night Ruka. Sleep well." Izuku said as Ruka smiled. And before she knew it, the combination of the warmth of Izuku's blankets and his comforting scent wafting off the sheets quickly put her to sleep. It wasn't much longer until Izuku fell asleep as well. Both of them slept soundly through the night.
~Time Skip~
The sun's early morning rays started filtering through Izuku's bedroom window at 4:32 AM. The gentle brightening of the room woke Ruka up. Her eyes fluttered open and she looked at the clock on Izuku's desk. Normally she didn't wake up this early. She had sunlight blocking shades in her room back at the U.A. dorms so her room was dark until she turned on the lights. She smiled softly as she stared at Izuku sleeping peacefully on the futon next to the bed. He looked so cute when he slept. He was cute when he was awake too, but when he was sleeping... absolutely adorable. Izuku started to mumble in his sleep.
"Ru...ka... Ruka... Don't leave me Ruka." Izuku said through his slow steady breaths as his brows furrowed slightly.
"I'm right here Izuku." Ruka said as she placed her hand on his cheek. He reached up and placed his hand on top of hers and smiled contently in his sleep. She stayed like this for a couple minutes then began to pull her hand away, but he grabbed her wrist.
"No, don't go." Izuku said as he tugged, pulling her out of the bed. She landed on top of him and he immediately wrapped his arms around her torso, holding her close to him. She tried to push up and free herself from his grasp, but he was strong, too strong. How was he this strong in his sleep?
"I won't let you run away... not again." Izuku said, holding onto Ruka tighter.
"Izuku..." Ruka said softly as she realized he must have been having some kind of nightmare where she had run away from him once before for some reason. She stopped resisting and hugged him back.
"I love it when you say my name like that." Izuku said huskily in a low voice. He started grinding his hips against hers. Ruka could feel something grow and harden beneath her and the blanket. She blushed when she realized what it was. It seemed his nightmare had shifted into a wet dream. Ruka tried to escape his grasp again, but he just held her tighter so it was no use. The upward thrusting of his hips against her nether region began to speed up. Not gonna lie, it did feel pretty good. It was starting to make her get all hot and bothered.
"Just a little longer... almost there." Izuku said as his thrusts became more frantic and sloppy. And then he stopped and lowered his hips. His arms began to relax as a satisfied smile made its way onto his face. He had just ejaculated.
"Izuku!" Ruka yelled which woke him up. He opened his eyes to see Ruka panting above him, her face flushed.
"What the hell!" Ruka said as she sat back on Izuku's legs. He just stared at her confused for a moment. Why did she look all flustered? Then he started to remember his dream right before he woke up. In the dream, he had just finished making love to Ruka. Oh God, did he just rape her in his sleep?! His face became a bright shade of red.
"I-I-I'm so sorry Ruka! I swear didn't mean to! I was asleep, I didn't realize..." Izuku apologized, his voice trailing off. There was an awkward silence for a while until Ruka sighed.
"Well I think I figured out who it is you're crushing on." Ruka said as she got off of his legs and stood up.
"Sorry." Izuku apologized again as he removed the blanket off of his lower body and stood up as well. There was a wet spot on his crotch where his sperm had leaked through his boxers and pajama pants.
"It's fine Izuku, don't worry about it. But you should change into clean underwear and uniform pants at least. And since we're joined at the wrist, you'll have to wait to put the rest of your uniform on after we get these shackles removed at school. All my uniforms are at school so I'll have to wait until we get there." Ruka said as Izuku's face burned a bright red again. She turned around to give Izuku some privacy as he changed out of his semen soaked pajama pants and boxers and into a pair of clean boxers and uniform pants. He then gathered his uniform shirt and tie and put them in his backpack. It was a little weird to have only the bottom half his uniform on and a casual shirt but it couldn't be helped. Izuku and Ruka sat on his bed and talked for a while to pass the time since they had both woken up pretty early. She explained exactly what had happened this morning to Izuku who apologized profusely.
"Again, I'm really sorry Ruka." Izuku said as Ruka shook her head.
"Like I said Izuku, it's fine. You were asleep, you weren't fully aware of what was going on. And besides, it wasn't completely unpleasant... It felt... kinda good actually." Ruka said as a light blush dusted her cheeks.
"Really?" Izuku asked Ruka who just nodded slightly.
"I probably wouldn't mind trying the real thing out with you." Ruka said in a quiet voice, her blush becoming a little more apparent as she averted her gaze to the side. Izuku found her bashful side adorable. But what she just said had him wondering.
"Earlier you said you figured out that I like you, but you never said if you felt the same way about me. And now you're saying you wouldn't mind having sex with me. Does this mean you like me back?" Izuku asked Ruka.
"You could say that." Ruka said with a teasing smile.
"In a friends with benefits sort of way or in a true romantic way?" Izuku asked for clarification.
"What do you think?" Ruka asked Izuku, dodging the question.
"Well you seem to like qualities of mine such as my nerdy side and my analytical thinking. You're a bit protective of me, growling at Monoma from Class 1-B when he elbowed my head and defending me when Kacchan said I didn't help you much with your studies because I got a lower ranking than you. You also kissed my forehead before I was about to leave after preparing for final exams. And considering we haven't even had sex yet, I'd say you like me more in a romantic sense." Izuku said, ending his mumbling rant.
"Well then, there's your answer." Ruka said as Izuku started to fidget a little on the bed.
"So, now that we've practically confessed to each other... Does that mean we're boyfriend and girlfriend now?" Izuku asked Ruka.
"Only if you want us to be considered a couple." Ruka said as Izuku looked into her crimson eyes with his emerald ones.
"I do want it, but... only if you want it." Izuku said as he gently grabbed Ruka's hands in his. She smiled softly.
"Sure. I'll be your girlfriend, Izuku." Ruka said as she leaned in and closed the distance between them. Izuku's eyes widened, but then closed as he melted into the kiss. He reached up with one hand and placed it on her cheek, gently caressing her with his thumb as they kissed. Their lips molded perfectly together as if they were made for each other. Both of them could feel their hearts beating hard against their chests. Ruka then started to slowly pull away.
"That was... wow. I never would've imagined my first kiss to be so magical. Makes me think you have some experience." Izuku said as Ruka shook her head.
"Nope. I've actually never kissed anyone before. You're my first." Ruka revealed as Izuku looked at her in surprise.
"Really? Well you're a really good kisser." Izuku complimented Ruka.
"You're not bad yourself." Ruka complimented Izuku back. Just then, Izuku's mother called out from the kitchen.
"Izuku, Ryuutou, I made breakfast for you." Inko said from the kitchen. The two teens then got up from Izuku's bed and headed out to the dining area to eat breakfast. After they ate, they headed to school together.
