Chapter Text
Giyuu walks out of the doctor's office silently and alone with his head down and makes his way home, he doesn’t stop off at the bakery for cake and coffee like he originally planned. He feels nauseous and lightheaded at the news he’s just recieved, even more nauseous and lightheaded than he’s been feeling for the last 8 weeks, that being the reason he was at the doctor's office to begin with, he just walks home in stunned silence.
“Good evening sir, welcome home, would you like me to prepare lunch?” One of his attendants greets him as he enters the water estate, Giyuu just shakes his head solemnly and goes straight to his room. He should be taking the attendant up on that offer, considering his current condition. He makes it to his room, slumping himself down on the bed, carefully of course. He lets out a huff of air and questions himself “what am I going to do now?” He cries out to himself “how did I even get myself into this situation?” But he knows, he knows exactly how, it all started eight weeks ago…
~~~🍃~~~
It was about a month after Giyuu had gotten out of the hospital and returned to the water estate, having lost an arm in the battle with Muzan, life was a little harder to adjust to but with the help of his attendants, he was managing quite easily, also the regular visits from the Uzui family helped keep his spirits up.
This time he was facing a different dilemma though, one he hadn’t come across before. Giyuu had always gone to Shinobu for his heat suppressants, but now with her gone, he’d not had the chance to get more, now his heat was approaching and fast.
He made the decision to give his attendants the week off, leaving himself alone at his estate. He lays almost uncomfortably on his bed, yukata loosely wrapped around him and the shoji doors wide open to let in as much as the cool breeze as possible. With the aid of heat suppressants, it’s been years since Giyuu last experienced a heat and he wasn’t very accustomed to the feeling.
He felt hot and bothered and wanting for something he wasn’t quite sure of, of course he knew what he needed but who exactly would he ask? He really wasn’t close to anyone at all and only knows of two alphas that he’s at least friends with, there’s Uzui but he was already mated, with his three omega wives at that and the other person he could possibly seek out was Shinazugawa, who he hadn’t seen since the dinner they shared after leaving the hospital a month ago, he’d just deal with it and ride it out alone.
He curls up into a ball and is trying to get some sleep, despite it still only being mid evening, the sun hadn’t even gone down yet.
He’s almost drifting off to sleep when he hears a faint noise, his eyes shooting open as he tries to listen out for the sound again. He hears it again, a knock at his door “who the hell?...” he wonders out loud, Tanjiro and urokodaki only visited a few days ago so surely it wasn’t them and Uzui and his wives weren’t due to visit until the weekend. He wonders who else could it be as they knock for a third time, he hopes that maybe if he ignores whoever it is they’ll soon go away. That is until he hears Shinazugawas voice call his name “Tomioka? Are you home?” The man calls out.
It’s been a whole month since he’s last seen Shinazugawa, since they shared dinner together as a peace offering after years of tension between them. He’d been lying if he said he wasn’t already missing the scarred man, fuck it! He thinks to himself, he guesses he could quickly see Shinazugawa at the door, explain to him that now isn’t a good time and make arrangements for another time. He throws himself up out of the bed, fixes his yukata the best he can with his one remaining arm and makes his way to the door.
“Shinazugawa, good evening, what can I do for you?” Giyuu greets as he coyly creaks the door open “yeah hi, where are your attendants?” The white haired man replies as he looks at the man before him “oh I gave them the week off” Giyuu quickly answers.
“Okay, anyway, I’m heading off to travel for a while, I thought we could have tea together one last time before I leave” Sanemi then explains looking at Giyuu with hopeful eyes. Giyuu begins to panic a little inside, he doesn’t want to turn him away, not if he’s leaving to travel but now really isn’t a good time “oh, when are you leaving?” He questions.
“First thing tomorrow morning, I plan on being gone for about a year” Sanemi replies “oh” Giyuu says looking down, there’s no way he can bring himself to turn the man away, he’s already started to miss him after having spent his whole recovery time in the hospital bed right next his. He figures he can deal just for an hour or so, his heat hasn’t hit in full force yet so he’s sure he’ll be fine. He holds the door open for Sanemi and leads him to the kitchen and dining area.
“So where are you traveling too?” Giyuu asks as he sits Sanemi’s cup of steaming green tea down in front of him before grabbing his own “nowhere in particular, seeing as much of Japan as possible and going as far as I can” Sanemi answers before continuing “I want to go back to where I lived with my family, I even want to visit the town Masachika was from too” he explains.
“That sounds wonderful, and you said you’re planning on being gone for a year” Giyuu replies “yeah, at minimum, I may be gone longer though” Sanemi says. Tea with Sanemi seems to be going fine so far but Giyuu is getting increasingly agitated as he’s noticing Sanemi’s scent getting stronger. He rubs the nape of his neck as he looks away from the other man, hoping the alpha hasn’t realized the state he’s in, his heat is suddenly getting increasingly worse very quick, he’ll have to wrap tea up very soon.
“Tomioka? Are you okay?” Sanemi questions, damn it! The omega thinks to himself “yeah, I… I’m fine” he answers, Sanemi just eyes him for a moment “yeah, whatever” he says before asking “so what about you? What do you have planned?”
Giyuu shakes his head “nothing much really, just the usual” he answers with a chuckle as his discomfort increases “are you sure you’re okay, you’re not looking so great” Sanemi then questions as he leans in closer to Giyuu, there’s still a bit of distance between them but it only makes his scent stronger to the omega as he attempts back away “no, no I’m fine” Giyuu frantically tries to assure.
“You don’t look fine” Sanemi returns as he slides closer to Giyuu, he brings a hand up to Giyuus forehead “do you have a fever?” he questions “no why?” Giyuu quickly exclaims and so Sanemi replies “are you sure? You’re so hot you must have…” Sanemi stops what he’s saying, he leans forward as Giyuu leans back on his hand “I promise, I’m fine” he says, giving Sanemi a quick smile.
“Tomioka?” The white haired man questions “are you?…” he leans forward and brings his nose down to Giyuus neck, taking in the strong scent of the omegas heat “you should’ve told me” He says looking back up at Giyuu.
“I’m sorry” Giyuu apologizes “if you want to, you can go now, I’m sorry I should’ve told you I just didn’t want to seem rude” he begins to ramble but Sanemi just shakes his head “it’s okay” he whispers leaning back into Giyuus neck “let me help you.”
“No, I can’t expect that from you” Giyuu says, it takes a lot of his will to say those words, he’s always wanted Sanemi, even from they day the first met, though his feelings were one sided for years, up until very recently, Sanemi held onto a strong hate for Giyuu. It’s taking his all to not just let Sanemi take him and ravage him right then and there, he wants to allow the alpha to do as he pleases with him but he’s certain those feelings are unreciprocated.
“Please, Giyuu” Sanemi whispers again, using his first name this time and resting his cheek against the others “just one night” he nuzzles his face against the omegas. Maybe I was wrong about his feelings! Giyuu thinks to himself, he’s beginning to realize why Sanemi’s scent was getting increasingly stronger, he closes his eyes to recollect himself for a moment but before he can, he feels soft lips connect with his own, he can’t bring himself to not give back, reciprocating Sanemi’s kiss with all willingness.
He can barely catch his breath as they break apart, he’s in his heat and he’s lost all sense within him to turn the alpha away “bedroom” he breathes out quickly.
As soon as they make it to his room, Sanemi pins him to the futon, he’s rough and Giyuu is quickly learning that he’s really into it. Sanemi straddles him and leans back down, kissing him deeply and aggressively, Giyuu gives back as much as he takes, his hips begin to thrust up into the other and he can feel the alphas already hard cock through the fabric of their yukatas, whimpering as the feeling.
Sanemi moves his lips down Giyuus neck, kissing and sucking at the spot just above his collar bone “Sanemi, please…” Giyuu begs for more. “Okay, just be patient” Sanemi breathes out as he feels Giyuus hips gyrating into his own. He sits up straight moves to place himself in between Giyuu’s legs and grabs at the obi belt at Giyuus waist “can I? Are you sure about this?” He checks before disrobing the man below him, despite their instincts urging them further on, he wasn’t about to force Giyuu into anything he didn’t want.
“Yes” Giyuu nods eagerly and within seconds the fabric is untied and his yukata is pulled open. Sanemi runs a hand up Giyuus stomach and chest, admiring the sight before him, even after this time of no longer training, Giyuu was still pleasantly toned and well built.
He leans back down and kisses in the middle of Giyuus chest and Giyuu moans at the simple contact, he needs more and he needs it quick, he needs Sanemi inside of him.
Sanemi makes quick work of moving his mouth all the way down to Giyuus hip, stopping to pull off his fundoshi and exposing him completely. He kisses past Giyuu’s hard leaking cock and then down to his thigh, licking his way down to his inner thigh. Then sitting up, he takes Giyuus legs by the back of the knees and pushes them up, exposing Giyuu’s hole, he dips down and licks over tight rim, getting a taste of the sweet slick leaking from the omega, causing Giyuu to cry out with the filthiest moan he’s ever heard.
He lets go of one of Giyuus legs, letting it drop to the ground and with his left hand, he runs a finger around the slicked up hole slowly pushing in, moving it in and out for a few motions before adding another finger. It’s tight but he feels Giyuu relaxing around him and as he pushing the fingers in and out he feels Giyuu continue to push himself back onto Sanemi’s hand. He decides to add another and as he fucks his fingers into Giyuu, the omegas thrusting becomes more erratic “Sanemi, please, I need it now” he begs the alpha again.
“Okay” Sanemi promises as he removes all three fingers. He quickly pulls off his own yukata and fundoshi and with the slick remaining on his fingers, he runs it along his own cock, lubing himself up “ready?” He asks and he takes Giyuus debauched whimper as “yes.”
He readies himself and pushes in, barely giving Giyuu a moment of respite before thrusting in and out. Was he being a little too rough? Yes but Giyuu seems to like it that way and it didn’t take much for him to lose himself on Sanemi. The feeling of Sanemi’s cock took him to new levels of pleasure he never knew could be felt as he moans and whimpers underneath the alpha, running his hand up his strong newly scarred abs and to his chest, squeezing at the muscle before running his hand up into the white strands of hair and pulling.
“Sanemi… “ Giyuu moans out as he tries to pull the white haired man’s head down into another kiss, Sanemi obliges, dipping down and resting on his forearms, grabbing at the freshly cut dark hair, he leans in to kiss the man below him. With no inhibitions to take it slow, they kiss one another fiercely matching each other’s pace as Sanemi thrusts unrelentingly into Giyuu, Giyuu giving back just as much as he receives.
Just as suddenly as they began, Sanemi quickly pulls out, sitting back onto his shins. He helps to maneuver Giyuu to sit with his back to him over his lap, pulling him back down onto his cock. He places an arm around the dark haired man’s waist as he pushes back in and begins to pound in again, he seems to be hitting the right spot now as Giyuus whines and moans become more erratic.
Sanemi brings his other hand up, holding lightly over Giyuus neck until his chin is cupped between his thumb and two remaining fingers, his ring finger resting between Giyuus teeth “come on Giyuu” he breathes out “are you going to come for me? Come on” he urges the omega on, who then takes his own dick into his hand, stroking it in time with Sanemi’s thrusts.
Sanemi takes the hand he has around Giyuus waist and places it over Giyuus, stroking the omegas cock together as one as he rests his mouth over the nape of Giyuus neck. Sanemi then runs over the head of Giyuus cock, pushing lightly down onto the cock until he has Giyuu coming into their hands with a loud fucked out moan.
The alpha resists the urge to clamp down onto Giyuus neck with his teeth as his own orgasm hits him moments later, instead biting the inside of his own cheek as he groans, pushing their bodies together as tightly as he can, they remain still for a moment, taking in the afterglow of the orgasm and catching their breaths.
As they stay connected together, Sanemi guides them down onto the bed together, on their sides and holding them tightly together and pulling the blanket over them. Sanemi would be content to just stay like this for as long as time would permit, he kisses the spot just behind Giyuus ear and the omega hums contently in response.
After moments of remaining just as they are, Giyuu mumbles “When did you say you were leaving?” Sounding hopeful “tomorrow morning” Sanemi gently whispers into Giyuus ear. “Okay” the dark haired man replies “but would you at least stay until morning, stay the night” he offers, Sanemi is more than willing to take him up on that offer, he carefully pulls out off Giyuu and turns him to face him “anything you want” he assures, then pulling Giyuu into him and holding him tightly.
~~~🍃~~~
That was eight weeks ago, Giyuu can only blame himself for the situation he’s in now. He should’ve known better, he hadn’t had a chance to get back onto his heat suppressants and because he was on heat suppressants and wasn’t usually sexually active, he hadn’t been on birth control either.
“How am I even going to explain this to sanemi?” He questions himself out loud “is he even coming back at all?” He worries about the prospects of his little predicament, or not so little as he had just received life changing news.
He paces up and down his estate, having done the only thing he could think of for now, he’d sent kanzaborou out and called for Uzui, figuring having someone to talk to might help.
“Tomioka? What’s up, is everything okay?” The former sound hashira questions, as he lets himself into the residence and finds Giyuu in his panicked state.
“Do you know exactly where Sanemi could be right now? How far has he traveled so far? When will he be back?” Giyuu frantically questions “woah, slow down there, did something happen, why all the questions about Shinazugawa all of a sudden and since when were you two on a first name basis?”
Giyuu decides it’s just better and easier to just get to straight the point, he rubs the back of his neck and lets out a breath “well you see” he starts off a little nervously “the night before he left, he came to say goodbye and I uh… I hadn’t gotten back on heat suppressants yet and we ended up, well you know…”
“Okay, I see, I’m listening” Uzui urges a him on and so Giyuu continues “anyway, Sanemi’s the only person I’ve been with in that way, he left the next morning and lately I’ve been feeling really nauseous and lightheaded so I decided to go see the doctor and it turns out…”
He pauses for a moment to take in a deep breath “I’m pregnant!”
