The moment Hizashi stepped into the bedroom, he was hit with the thick scent of coffee and cinnamon — warm, grounding, and undeniably Shouta. It rolled over him like a wave, sharp enough that he instinctively raised a sleeve to cover his nose. "Whoa— okay, that's strong," he muttered, blinking through the haze. "Hey, Shou? You happen to know what today is?"
From across the room, Shouta barely looked up from the dresser he was raiding. "I don't know. End of the month? Why?"
Hizashi leaned against the doorframe, watching as Shouta pulled out another one of his hoodies and tossed it onto the bed — right on top of the growing pile of blankets and clothes forming his usual nest. His movements were automatic, unthinking. "No reason in particular," Hizashi said lightly, fighting a grin.
Shouta's voice came out with that familiar dry edge. "Zashi, if you've got something to say, just say it."
"Alright," Hizashi said, stepping closer, amusement dancing in his eyes. "My love, do you not realize what you're doing right now?"
That made Shouta pause. He looked down at the cozy pile of Hizashi's scent-soaked clothes, then back up at his husband, who still had his sleeve pressed to his face. "...oh, shit."
Hizashi burst out laughing. "Yeah, babe. You're going into heat." He crossed the room, gently pressing a hand to Shouta's forehead. "And judging by the fever, it's hitting fast this time. You should probably lie down before it gets worse."
Shouta groaned, shoulders sagging. "I don't need you babying me every damn heat cycle. I'm fine, Zash."
"Hey, it's literally in my blood to take care of you," Hizashi teased. "And, if you recall, in our wedding vows. Also, I can smell you from the kitchen— so denial's not gonna work this time."
"Oh my god," Shouta muttered, dropping onto the bed with a groan. "I hate this. I wish I could just stay on the hormone blockers and skip the whole thing."
"Yeah, but they were making you sick," Hizashi reminded him, already grabbing the water bottle and a couple of ibuprofen from the nightstand. "In the grand scheme of things, this is better. Plus, hey— we get a week off every three months."
Shouta took the pills and muttered dryly, "Oh, goodie. A week off to be a weirdly horny freak."
Hizashi grinned, tilting his head. "I happen to like you weirdly horny and freaky."
"Yeah, because you get laid," Shouta shot back. "Of course you like it. You're a whore."
"You're the one who begs me every single time," Hizashi countered without missing a beat.
Shouta tried not to smile, failed, and shook his head. "I don't think I was that sick from the meds."
Hizashi's tone softened. "Shouta, you started having seizures."
That shut him up fast.
Eventually, he sighed, running a hand through his hair. "I'm tired."
"Yeah, I can tell," Hizashi said as he found the heating pad and plugged it in next to the nest Shouta had built. "Lay down and take a nap, I'll come check on you in a bit."
Shouta fixed his nest to the rest of his liking, then curled up in the middle of it with the heating pad on his stomach. He grabbed one of Hizashi's favorite hoodies and held it close, his scent from it helping soothe him and slip into sleep just as the pre-heat effects started to hit him.
By the time Hizashi was done making sure everything was set for their heat and rut, he could smell Shouta's scent getting more and more intense from across the house. It was coming on quick, faster than usual. Normally, with his heats, there's at least a 1-day buffer before his full heat begins.
He forced himself to calm down, holding onto the small bit of level-headedness he had left before getting hit with full-on rut-induced brain fog. Then walked into their bedroom, the sweet smell of Shouta's scent filling the room. His eyes were immediately drawn to his mate, who was in the middle of the nest, curled in on himself, with a pained look on his face.
"Fuck.." He walked over to the bed, before he even had the chance to ask if he could go in his nest, Shouta grabbed him by the wrist and pulled him down. "Hey, love." He whispered, cuddling close to him. He kissed down his jawline and his neck, the pheromones making his mind race with all the things he wanted to do with him.
Shouta panted as he reached down, sloppily untying his husband's strings to his sweatpants. And sense of dignity or conscience was replaced with a need for his mate to make him feel better.
"Hey, hey, slow down." Hizashi gently moved his hands. "I got you, lay back, sweetheart."
"It hurts," Shouta muttered as he rolled onto his back.
"I know, I'll help." Hizashi kissed him softly before slipping off his pants and boxers, his slick already dripping down his thighs. "Shit." It took everything in him not to jump on him in that exact moment, although he knew that's what Shouta wanted, he knew he had to prep him at least a little so he would be as comfortable as possible.
Hizashi carefully slipped one finger in, thrusting in and out, eventually adding a second and a third. He kissed his neck, jaw, lips, cheeks, and any and every part of his mate. The sounds of his breath picking up only made his dick more painfully hard in his sweatpants.
"Zash--please." Shouta's voice was more of a whine than anything.
"Okay." Hizashi kissed him as he pulled his fingers out. His pants were ditched a moment later. He watched Shouta's eyes for any sign of discomfort, being sure he was okay before lining himself up. He held onto his hips as he slowly pushed in, fighting the urge to buck his hips forward. He waited for Shouta to adjust and relax before starting to thrust at a slow pace.
Shouta relaxed his head against the pillows, the painful feeling he had earlier replaced with building pleasure. Each movement sending a shockwave through him. He wrapped his arms around Hizashi's neck, pulled him closer, breathing in the scent his rut was letting out, easing his mind and muscles.
The pace quickened, breaths quickening as they fucked. Hizashi left little love bites on and around the mate mark he placed on Shouta years ago. Desperate whines and moans filled the room as Shouta came.
"Shou--ah--I'm g-onna." He could barely finish his sentence, drunk off the hormones and scent from his mate. He bit his neck as he moaned, his knot swelling. He held him close, pressing soft kisses where he had bitten earlier.
After a little while, Hizashi was able to pull out. He pulled Shouta into his arms, rubbing his back as he held him close. "I love you."
Shouta sighed contentedly as he nuzzled closer. "Mm'love you too." The pain he had earlier vanished, surrounded by cuddles and soft kisses.
He hated the fact that he had to put up with his heat now.
But it's not so bad with Hizashi.
