Katsuki slips through the front door, kicking off his shoes, before he steps further into Ochako’s apartment. They had been courting for a few months now and Katsuki was apprehensive. He knew her heat was this week, so why was he here? He wasn’t just going to assume shit and think it meant she wanted to take things a step further. Although, he had to admit he definitely wouldn’t be opposed.
Katsuki followed his nose, tracing Ochako’s strong pheromones to her bedroom. It was thick with the scent of her heat, and Katsuki drew a hand up to his face to try to block out some of the scent so he’d remain calm.
Ochako’s text had sounded serious. She begged Katsuki to come over and help her, but as he stepped further into her room he couldn’t see her in her nest. Not even buried inside of the layers of sheets and blankets. His alpha growled, telling him his scent should be there too, but he shoved down the instinct and continued to search for her.
“Katsuki?” her voice called out from down the hall. “Is that you?”
His heart quickened at her tone. She sounded like she was in pain. Help omega , his inner alpha growled. He wasted no time slipping out of the room and followed the direction her voice had come from. It didn’t take long at all for him to follow her scent to the bathroom where she lay, naked, in her walk-in shower leaning up against the wall. She looked awful. A panting, sweaty, and pained expression was on her face. Her bangs clung to her forehead in wet strands and Katsuki ignored his logic and stepped into the small closed space with her.
Her sweet scent made his head feel fuzzy, but he had to focus. This wasn’t about him. This was about her.
“Ochako? Are you okay?”
“It all hurts,” she replies. Now that he’s there, her resolve seems to break down and she reaches up feebly for him to embrace her. “Alpha, it all hurts so bad. I have to pee but it hurts too bad.” So that’s what this was about. Instantly Katsuki is crouching down, pulling Ochako’s body into his own and allowing her to scent him as she tries to calm herself.
“Is that what this is about? You needed help with this omega?” Katsuki practically whispers. His hands are trembling while he fights the urge to give in and scent her back. This wasn’t about him, he reminds himself once again. His one resolve.
“Yes!” Ochako wails. “It hurts so bad when I try to go, alpha. Needed you here. Please. Help.”
He isn’t quite sure what he can do about it. He’s heard some omegas can sometimes have issues with this, but he’s never met or heard about anyone he’s known having them. Which meant he was out of his depth. He reaches into his back pocket to retrieve his phone, twisting his head away so he can look at his screen. He unlocks it, clumsily, with one hand before clicking on his browser icon. It’s slow, but he types out his question into the search bar.
“Omega heat can’t pee”
The results pop up quickly. All things he already knows about. He clicks the top link while Ochako continues to tremble and whine against him, burying her face into his neck like she’s trying to melt into his body. He scans as quickly as he can, shushing and comforting Ochako while he searches for a solution. At the very bottom, way too far down, he finds a small list.
“Have you tried heat?” Katsuki asks. He feels lame, like this is an obvious solution. It makes him feel like he’s talking down to Ochako and that’s not what he wants to do but he needs to know what she has and hasn’t tried from the article’s suggestions. Based on what he could see, he figured she couldn’t go because her body was clenching up. Making it painful and hard to go since the pain probably only added to that stress. “We need to relax your muscles, Ochako.”
“Yes,” she whined. “I tried heat, alpha. Didn’t help.”
“Your…your toys?” Katsuki asked shortly after. “Have you tried your heat aids?”
“Can’t fit. Hurts too bad,” she whines again. Katsuki’s alphan instincts are kicking into high gear and all he wants to do is crowd her into the corner of the shower and bathe her in his scent. To soothe his omega and make her feel better. Not his omega! Katsuki can’t help the frustrated growl that rumbles through his chest, irritated at the way his instincts keep fighting him. His growl only makes Ochako whimper beneath him and Katsuki clenches his eyes shut.
“I’m not growling because of you, Ochako. You’re fine. It’s okay,” he soothes. “I’m just frustrated because I want to help but-” he cuts himself off before he says something that is definitely not what a good alpha would say.
“Okay,” she responds meekly.
“If you can’t fit anything because of the pain, then have you tried just your finger? It might help you relax so you can go. I think your muscles are all tense because of your heat.” She doesn’t fight him on it, merely nodding in agreeance against his shoulder in response. “You’ve tried it?” Katsuki asked. She shakes her head.
A heavy silence settles between them while Katsuki’s mind races. He doesn’t know if he should ask, if he should even offer, because it almost feels predatory. He’s above his instincts and he doesn’t want to do anything that would upset her after her heat. One soft plea for him to do something is all he needs to break his resolve. Ochako would understand. He’d do this and then leave.
“Would you like me to try, Ochako?”
Another beat of silence before a small nod. He had permission.
She was already undressed from her heat, so he didn’t have to undress her, but he did want to undress himself so he wouldn’t get any of her pee on his clothes. “I’m going to undress and then I’ll be back in here to help you, okay?”
“Please, alpha.”
He gently unwraps himself from her grip, pulling away and standing before he steps out of the shower to undress. He makes sure to place his clothing neatly on the edge of her sink’s counter. He debates taking off his boxers before ultimately deciding they should probably be taken off as well. Katsuki slips back inside the shower once undressed and sits next to Ochako. He pulls her closer to him, letting her lean her body against his side, head against his shoulder, before he gently grabs her leg and pulls it over his body to open her up.
She reaches out to grip his arm, tiny nails digging into his skin, while he gently trails his fingers down to her core. This was to help. He needed to behave, regardless of the swelling of his cock. With her thighs parted she smelled so much better and he was salivating while he plunged a single finger into her. “
“Let me help you, okay?”
His voice almost sounds disconnected from himself. She was so soft and her body was practically burning around his finger. She lets an uncomfortable moan beside him and Katsuki bites down on his own cheek to distract himself from the noises she makes as he continues to finger her and stare straight ahead into the wall.
Each time she shifts against him, rolling her body back against his hand, he bites down just a little harder.
Katsuki remains in this agonizing limbo for what feels like ages as he slowly works her toward an orgasm. He knows it wasn’t that long in reality, even less since she was in heat and he was aware omegas were more sensitive during their heats. So when Ochako clenches her hands around his bicep and buries her face into his shoulder, crying out softly, he can’t help but feel relieved.
He’s happy she must feel relieved too because as soon as her tiny spasms stop, her body relaxes and he can feel a gentle stream of hot piss soaking his hand. He continues to move his fingers inside of her, worried that if he stops her stream might stop as well. And he couldn’t do that. He needed to show her he was a reliable alpha. A strong alpha for such a good omega.
Katsuki needed to get out of here before he slipped into his own rut.
Minutes had surely passed by the time Ochako’s bladder was empty and Katsuki withdrew his fingers from her. He was tempted, for a moment, to lift them to his mouth to taste her, but at the last moment, he stops himself. This was getting into dangerous territory and the last thing he wanted was to take advantage of her. He stood up gently, making sure Ochako was okay, before he adjusted the shower head to spray in the opposite direction against the glass wall and turned it on.
He held out his hand in the water while it heated, adjusting the knobs until he was satisfied with the temperature. The hot water would help her cramping and aches.
Next, he gently lifted Ochako up and cradled her against his body, and maneuvered them so they were underneath the hot stream. Ochako let out a pleased sigh as the water hit against her body and Katsuki couldn’t help the proud purr that rumbled through his chest. He was being a good alpha. Providing for his omega. Making her feel better.
He took his time to let her soak underneath the water before he reached out for the shampoo and gently scrubbed it into her hair. She continued to melt against his body at the sensation, letting out small moans and whines. He could smell her arousal. It swirled around them, thick and heady like the steam from the shower. He ached to be inside of her, but it could wait. Just until she was better.
He rinsed the shampoo from her hair and reached for the conditioner next, combing it through her short hair with his fingers and letting it soak in while he grabbed a sponge and her body wash. Strawberries. Just like her scent.
Although his instincts screamed at him to claim her, he remained courteous. He lathered up her body gently, making sure she was clean and kept his touches polite. Even when he crouched down to wash her legs and could smell her delicious cunt right in front of his face. The saliva pooled in his mouth but he didn’t bury his face between her thighs like he wanted. Even though he was sure she would let him. Make his omega feel good. Good omega. Reward her.
Katsuki quickly stood, rinsing Ochako off before he turned off the water and stepped out with her. He held his breath as long as he could, wrapping Ochako in one of her fluffy pink towels before he grabbed his clothing and a towel and stepped out. He didn’t trust himself to speak, let alone act, and removed himself as quickly as he could.
Outside of the bathroom he already felt better; even if his whole body screamed at him to walk back into that room and show Ochako just how much he deserved her. He dragged himself to the furthest corner of her apartment before he finally dressed. He even went a step further and stood out on her fire escape in the fresh air once he was dressed to clear his head from her pheromones. So he wasn’t on the cusp of a rut any longer.
Once he was certain his head was clear, Katsuki stepped back inside and wandered back to the bathroom to make sure she was okay. He was relieved to see that she had left. He trailed her scent to her room and peeked inside, relieved to see her curled up in her nest. He was prepared to leave before she called out for him gently.
“Alpha?” Katsuki’s knuckles turned white around the door knob.
“Yes, Ochako?”
“Thank you.”
Katsuki couldn’t help the smile that ghosted along his lips. “Anytime,” he replied before closing the door and retreating from her room. He slipped his shoes back on and left Ochako’s apartment. His inner alpha thrummed with pride for the rest of the day.
