To most people’s surprise, Katsuki Bakugou handled going deaf rather gracefully. He knew by age 12 that his quirk was already affecting his hearing; it was to be expected. All quirks had some sort of physical ramifications. For instance, Eijirou’s quirk made his joints stiff and his skin sensitive and Jirou often dealt with headaches when she overused her quirk. So Katsuki started wearing hearing aids in his second year at UA and by the time they graduated, his hearing was practically gone.
However he didn’t let it affect his job. He utilized support weapons and upgrades to his costume to make him aware of his surroundings at all times. Most of his close friends had learned at least a basic level of sign language and Katsuki had become a master at reading lips after weeks of training with Present Mic. With the help of therapy, he was able to cope with it. But the deafness hurt the most when it came to his relationship with Eijirou.
They had started dating at the end of their first year. Katsuki had warned him that he was going deaf and if it bothered Eijirou, he could fuck off. Kirishima had just laughed, held him close and pressed his lips close to Katsuki’s ear.
Don’t worry. I’ll always be by your side.
Katsuki remembered the day he stopped being able to hear Eijirou’s voice. He had locked himself in their room and sobbed until he felt the bed dip and someone’s lips press against the back of his neck.
“What’s wrong?” Eijirou signed
“I can’t hear your voice. I’m going to forget what you sound like,” Katsuki signed back.
“I’ve always been too loud anyway. You’re not missing much.”
“I’m being serious.”
“I know. I’m sorry baby. Here,” Eijirou said. He took Katsuki’s hand and pressed it against the base of his throat where he could feel the vibrations.
“What are you doing?” Katsuki asked
“That’s what it feels like when I say I love you,” he replied. Katsuki rolled over and wrapped his arms around Kirishima’s waist, pressing his face against his chest so he could hear his steady heartbeat.
Although they had been together for nearly three years, they hadn’t had sex or had done much of anything sexual. Katsuki rarely wanted to do anything sexual, his sex drive was barely existant compared to Eijirou’s. Kirishima had reminded him on numerous occasions that it was absolutely fine. He wasn’t with Katsuki for sex and he’d rather die than make Katsuki feel uncomfortable. But the day Katsuki walked into their apartment and declared that he wanted to have sex, Kirishima was ecstatic. Until the day came and he found Katsuki sitting on their bed, staring solemnly at the floor.
“Maybe I should bottom,” Katsuki signed.
“Why? I thought you didn’t want to,” Kirishima replied.
“What if I hurt you or it doesn’t feel good? I won’t be able to tell because I can’t hear you.”
“We’ll go slow. I trust you Katsuki,” he said.
Katsuki nodded and let Eijirou take his hands and drag him into the bathroom and into the hot shower he had prepared. They kissed and held each other under the hot water, getting themselves into the mood. Once they were done, they toweled each other off and Kirishima lit some candles while Katsuki grabbed the lube. He gestured for Kirishima to lay down on the bed, pillow propped under his hips. He settled between Eijiro’s legs, rubbing his thighs lightly.
“Touch me,” Kirishima said. Katsuki uncapped the lube, drizzling it over his fingers. He rubbed his hands together to warm it up. He watched Eijiro’s face as he opened him up.
“Feel okay?” Katuski asked. He was incredibly self conscious of his voice, he knew it was loud and mumbly but both his hands were occupied.
“Yes baby, keep going,” Eijirou encouraged, reaching down to squeeze Katsuki’s hand. Katsuki’s chest felt warm when he looked down at his boyfriend. Kirishima’s face was so open, expressive, and earnest. Katsuki was thankful he found someone so willing to barre their entire soul to him. He curled his fingers, searching for a spot he knew would drive Ei crazy. He knew he found it when Eijirou’s back arched and his mouth fell open. He continued working his fingers until Eijirou grabbed his wrist.
Katsuki froze immediately. “Did I hurt you?” he asked.
Eijirou shook his head, color rising on his cheeks. “No. I almost came. Fuck me, please Katsuki,” he signed, fingers shaking. Katsuki nodded and coated himself with more lube.
“This position?” Katsuki asked.
Kirishima shook his head. “Can I be on top?” he asked. Katsuki nodded and they quickly switched positions. Kirishima straddled Katsuki’s hips and slowly lowered himself on top of him. He placed his hands on Katsuki’s chest as he slowly rocked his hips. It was tight, and not completely comfortable at first but started to feel better as he relaxed.
“Fuck,” he moaned, throwing his head back. The angle felt amazing. But when he looked down at his boyfriend, his heart sank. Katsuki’s eyes were
filled with tears that threatened to spill.
“What’s wrong?” he signed.
“Can’t hear you,” he signed back. Kirishima’s heart broke for his boyfriend. He racked his brain for a moment before he grabbed Katsuki’s hand and placed it on his throat.
“Keep it there,” Kirishima said. He rocked his hips even harder, dropping his mouth open as he moaned loudly. He normally wouldn’t be this loud but he’d be damned if his boyfriend didn’t know how good he made him feel. And it felt sexy to completely let go.
“You feel it? Do you feel the vibrations?” Kirishima asked. Katsuki’s eyes were wide, his pupils blown out. He nodded, tightening his fingers ever so slightly.
“Shit, Kat. It’s so good,” Kirishima babbled. Katsuki’s other hand, traveled over Kirishima’s body, feeling his naked hot skin. Suddenly he sat up, wrapping his arms around Kirishima’s waist. He pulled him into a deep dirty kiss. He felt Kirishima’s lips vibrate against his and suddenly he felt a warmth coat his stomach. He looked down and grinned when he saw that Kirishima had finished. Kirishima smiled back at him.
“Come for me,” he said. He continued to rock on Katsuki, leaning forward to kiss and nibble Katsuki’s neck. It didn’t take long for Katsuki to come. He let out a loud groan, burying his face into Kirishima’s neck. He carefully pulled out and lowered them both down onto the mattress. Bakugo kissed Eijiro on the cheek before he left bed to grab a warm, damp washcloth and a couple of water bottles. He carefully cleaned Eijiro off as the other man sipped on his water. He tossed the cloth into their laundry basket and climbed back into bed. He turned on his side to face his boyfriend.
“You okay?” he signed.
Kirishima smiled softly. “I’m perfect, baby. How about you? How are you feeling?” he asked. Instead of answering, Katsuki leaned forward and pressed a kiss to Eijiro’s forehead. Eijiro sighed peacefully and cuddled closer to his boyfriend. He cradled Katsuki’s head against his chest and gently ran his fingers through Katsuki’s soft blonde hair.
