“You should’ve gotten married later,” his mother has always said, “it would’ve lasted longer if you waited.”
But Keisuke’s always been impulsive, and though the pet shop still smelt of fresh paint, the cages were still empty, he got down on one knee at the age of twenty-two and asked you to be his wife. He could only promise you his heart, for some reason, that was enough.
Then the baby came along when he turned twenty-five, all while Keisuke was doing his veterinary degree, the degree that had at one point seemed never ending. Mostly because he couldn’t get his head around it, he’s struggled all his life with studies. It got too much at one point, the two of you had grown old too quickly, the spark had died out too fast. Hayako was only three when the two of you decided to give it a rest, divorce would be the healthiest option, all you did was argue and make each other upset.
Obviously, your daughter didn’t take it to heart since she couldn’t comprehend it, but Keisuke did, he missed coming home from work to find her waiting for him. He missed letting her sleep on his chest at night. Now he would come home to silence, he would make his dinner on his own, eat on his own, sleep on his own. It’s been like that for four years now, and sadly, he’s grown used to it, only having Hayako on the weekends is the price he pays with such a demanding job.
“Mommy has a boyfriend,” Hayako says, sitting in the passenger seat of his car, chewing on a chicken nugget. A measly dinner, the only thing he could get on the way to pick her up, he didn’t want to be later than he already was. Keisuke swears to himself he’ll cook up something nice and hearty tomorrow.
“What?” You’re allowed a boyfriend, it’s been four years, he’s had plenty of on-and-off flings, a couple serious relationships - it just makes him do a double take.
“Mommy has a boyfriend,” she repeats, this time while shovelling more than just a few fries into her mouth.
“Oh, okay,” he nods slowly, glances at her and then back at the road. “Did mommy ask you to tell me that?”
“No,” Hayako shakes her head, “just wanted to tell you.”
“You should let mommy tell me in her own time.” Keisuke tells her, it’s more of a light warning than a scolding, and Hayako doesn’t seem bothered by it. “What’s his name?” Keisuke can’t help himself sometimes.
“Hanma.”
“Hanma what?” Keisuke prods, he really shouldn’t be intruding on your personal life until you’re ready to tell him.
“Hanma Shuji.” Hayako says, “I don’t like him.” She uses her sleeve to wipe ketchup off her face, Keisuke reminds himself to toss the sweater in the wash when they reach his apartment.
No way. Hanma Shuji from way back when? Shady guy in Toman? The one he tended to stay away from, they bumped into each other a few years ago at Takemichi and Hina’s wedding, Keisuke still ignored him. That dude had a weird air to him.
“Long hair? Freaky eyes?” Keisuke can’t stop his mouth from running.
“Mhm,” Hayako wipes her hands on her new blue jeans, then she crushes the cardboard Happy Meal box down, “mommy says he’s a photographer.” She stumbles over the word cutely, her little lisp becoming more noticeable.
That’s definitely creepy Hanma then. What a small world it is. While he’s not extremely happy with the news, it’s not like he has the right to even have an opinion on it. So Keisuke shuts his mouth.
“Has he stayed over before?” Keisuke asks before he can help himself, he hoists Hayako onto his hip since the elevator in his building isn’t working.
“Huh?” She wraps her little arms around his neck as he walks up the flights of stairs to reach the fifth floor.
“Hanma, has he stayed over at mommy’s house?”
“Yeah, daddy,” Hayako blinks at him cutely, he sets her down on the ground when they get to his front door, jamming the key in the lock. So you’re already that smitten with him? Letting him meet your daughter and everything. Keisuke bites his tongue again, he can’t judge you, this is the first boyfriend you’ve had in years. You’ve dedicated everything to your daughter, Keisuke’s the one that’s made Hayako meet more than a few women.
“Has she introduced you to him?”
“Mhm.”
“You don’t like him?”
“I hate him,” Hayako sticks her tongue out, “I hate her as much as that lady who stayed over at your house.” Her thick brows furrow together, similar to his.
“A lot then, huh?” Keisuke chuckles, he ushers her into the apartment, hanging her coat up and placing her shoes on the rack.
“Yes a lot, daddy.”
“When did you meet him?” Keisuke asks.
Hayako becomes exasperated by his questions, rolling her eyes, “on my birthday.”
For some reason, his heart sinks in his chest, on her birthday he had to cut the day short since he got called into work for an emergency. As much as he loves his job, it’s unpredictable, sometimes he has to drop Hayako back home to tend to another animal. “Right. A few months ago then?”
“He dropped me and mommy home.” Hayako rubs at her eyes, padding into the bedroom when she unzips her backpack to change into her pyjamas.
“Right,” Keisuke smiles sheepishly at the ground, he’s the one that drove you and Hayako to the aquarium, so how would you make your way back? It had crossed his mind, but Keisuke’s brain is too small to comprehend too many things at once. What an asshole, he hadn’t even bothered to call a taxi for the two of you, he didn’t even think to drop you home on his way across town. He recalls his daughter’s disappointed face, but she smiled nonetheless. Hayako’s always been understanding, she’s a good kid, his pride and joy.
“Hi, angel,” you greet her on Sunday evening as usual, Baji leaves too early to drop her off to school on Monday.
“Mommy,” Hayako squeals and hugs your waist, Keisuke smiles down at her affectionately.
“She had dinner already.” Keisuke says as he fiddles with his fingers, looking at his shoes which is odd for him. You wonder if Hayako told him something she shouldn’t have. She’s just a kid, slip-ups happen so you can’t be mad at her.
“Babe? You want me to wash the dishes?” A figure partially obscured comes into view, it’s none other than Hanma, he pokes his head past the doorframe.
“Hm?” You seem rather flustered by his appearance, your eyes getting a little wider as you stumble over your words. “Um, yes, Shu. If you don’t mind.”
“No problem.” His hair is longer now. Going past his shoulders. You must have a type. “Oh, no way, Baji, it's been years, man.” He grins and it’s slightly unsettling. Hanma offers his hand, Keisuke takes it because he should be a civil man no matter how angry he feels. He shouldn’t be so entitled. You’re not his wife and you haven’t been for years.
“Yeah, years,” Keisuke would’ve liked to keep it that way, he could’ve gone the rest of his life without seeing this creep. “I should go now.”
“Daddy,” Hayako clings to him, pressing her face into his stomach, “love you.” Her voice is muffled, he wraps his arms around her.
“Love you too princess, I’ll see on Friday, yeah?” He ruffles her hair, getting a little grunt of annoyance in return.
“Keisuke’s lookin’ good, huh?” Shuji wriggles his brows, “left him for lil ol’ me?” He wipes his hands on the tea towel.
“I didn’t leave him for you,” you scoff, packing away the leftover food into a plastic container.
“What’s up with him anyway?” He wraps his arms around your waist, lips pressing to the delicate skin of your neck, his teeth grazing it. “Made it big?”
“He’s a vet.” You murmur, lashes fluttering at the pleasurable sensation.
“Mmm, must be makin’ big money, eh?” Shuji’s teeth catch on your earlobe, the tip of his tongue tracing back down your neck, leaving a shiny trail of spit.
“I don’t know, Shu.” Your lips puff out into a sweet pout that he can’t help but kiss, “why are you so interested in him?”
“My competition.” He lets go of you when the tell-tale footsteps alert you of your daughter.
“Mommy, I can’t find my teddy.” She complains, you take her hand, missing the snarky look she throws at Shuji. While you have an inkling that Hayako isn’t fond of your new boyfriend, she’s never directly stated she’s uncomfortable around him. You’ve asked her a multitude of times whether she’s okay with Shuji, and Hayako has said yes each time.
“Did you leave it at daddy’s house, baby?” You check under her bed, in her wardrobe, until she grows tired and asks you to get in bed with her.
“I wish you and daddy would live together, so I didn’t have to lose my teddy.” Hayako mumbles quietly, her small face pushed into your chest, you cup her round cheeks and press a kiss to her forehead. She looks so much like Keisuke it’s crazy, even the way she pouts, how her nose wrinkles up. It’s all him.
“I know, baby. I’m sorry you lost teddy.” You know it’s not about the teddy, but you don’t want to upset her further. “Daddy can bring it over tomorrow night, yeah? I’ll ask him if he can stay for dinner too.” That seems to quell any arising sadness, she nods her head and tucks it beneath your arm to fall asleep.
Hayako wakes up in a bad mood when she notices Shuji is still over, he’s scratching his stomach and yawning, watching some shitty talk-show. “Did daddy say he’d come?” She sticks out her bottom lip, eyes shining with hope as you place a bowl of cereal down on the counter.
“Mhm, daddy said you left your sweater too.” You grin when she lets out a happy noise, she won’t be grumpy all day now. You shove her school bag in the trunk next to you work bag, Shuji gives you a kiss in the doorway that makes Hayako scrunch her nose in distaste.
“He’s gonna steal something from us, mommy.” She tries to tell you quietly, but Shuji hears and guffaws. He finds her funny, you find her pretty rude, embarrassed that she would say such a thing in front of him.
“Hayako,” she straightens up when she notices the change in tone, “that’s rude. Say sorry to Shuji.”
She sticks her tongue out and runs towards the unlocked car, shutting the door before you can drag her out by her ear and force her to say sorry. “It’s okay, babe. She’s a kid.” Shuji cups your cheeks, kissing the exasperated pout off of your face, “I’ll have breakfast and get out, won’t steal anything.”
“I know you won’t, Shu,” you push his chest with a frown, “love you, see you tomorrow.”
“Don’t have too much fun without me tonight, yeah?” His lips twitch upwards, “don’t want you fallin’ in love with Keisuke again.”
“Shut up, Shu.” You shove him lightly again, “I gotta go, she’s gonna be late.” You check the time on your phone, one more kiss and you leave to drive Hayako to school.
“I’m excited to see daddy.” Hayako’s mood always improves when she talks about Keisuke, you wonder if she talks to Keisuke about you in the same way. If her eyes light up and her gums show. You feel bad most days, for depriving her of her father, but how else would it ever work out? Even if the two of you stayed together, Keisuke would still only see her on weekends, he wouldn’t be there to send her to bed, and he’d be gone by the time she wakes up for school. You don’t blame Keisuke for that.
“I know you are, angel. He’s excited to see you too.” She gets a kiss on the head before she gets out the car, skipping through the school gates to greet her friends, bag slung over her shoulder.
Throughout the day, you start getting nervous for some reason. For no particular reason too. At work, something gnaws at your conscience, your stomach flutters and not even in a good way.
It can’t be Keisuke, can it? Stupid Keisuke, the dude you married for a good six years, the one you knew inside out, the one that was by your side when you gave birth to your daughter - there’s no need to be thinking about him like that though. He’s Keisuke. The man you’ve been co-parenting with for four years, the man you see for five minutes on a Friday evening and for two on a Sunday evening. The one you only meet on Hayako’s birthday, Christmas and occasionally Halloween. When you start to think about it, maybe the two of you should meet up more frequently for the sake of Hayako.
You’re even thinking too hard on what to wear, who cares, it’s Keisuke. Keisuke your ex-husband who spent half his life in scrubs covered in animal vomit. That’s no one to impress, still, when you get off your shift early - you put on a skirt shorter than your usual ones, and a cute low cut shirt. There’s something seriously wrong with you. It must be Shuji’s teasing from last night. That’s the problem.
“Mommy, you look pretty,” Hayako compliments when she gets back into the car, her hair is messy and out of place by the end of the day like always.
“Do I?” You laugh nervously, nails tapping against the steering wheel as she scrutinises your face. A full face and for what. To have dinner with your ex-husband, not even anywhere fancy, you’re making food at home for fucks sake.
“Yes, is it for daddy?” It’s an innocent question that makes you jump out of your seat.
“Because I felt like it, Hayako.” You mumble, your seven-year-old daughter even thinks you look better than you usually do on a daily basis. Heat spreads throughout your body, but you focus on asking her about her day on the way back home.
“Daddy’s coming, daddy’s coming,” Hayako sing-songs as she makes her way upstairs to wash her face and hands. You smile at her excitement, making her happy is the only point of today. It’s not to show off how hot you still are to your ex-husband.
Bringing flowers was a stupid idea. Keisuke should've just brought the dessert like you asked. There was no need to go the extra mile and bring flowers like this is a date. He’s having dinner with his ex-wife. His heart is in his throat when he knocks on the door, the only reason he doesn’t turn and run is because of Hayako.
“Daddy’s here!” He hears his princess through the wood of the door, his heart races when he hears your voice faintly.
The door opens, your head poking past the frame, a tight smile on your lips when you see him. Keisuke enters when you let him, he tries not to look you up and down, but he does. Age really has done you well. Not that you're old, the two of you are still young, you just look different now. More mature, a refined sense of style, your makeup skills have improved by a mile. Keisuke notices stupid things like that. The last time he saw you up close for a prolonged amount of time was on Hayako’s birthday.
“Daddy!” Hayako jumps into his arms when he puts the cake box and flowers down on the dining table, he lifts her up and kisses her cheek.
“You saw me yesterday, baby, you miss me that much?” He catches the fond look in your eyes as you watch the two of them with clasped hands, your hand looks empty without the glint of the wedding ring. Why after all these years is he thinking about you like this? Just when you’ve finally moved on with your love life.
“I miss you everyday.” Hayako says simply, her smile is strangely wistful for someone so young. “Daddy, what cake did you bring?” She switches topics fast, her brain is always moving a million miles per second.
“Chocolate,” Keisuke lets her down on the ground so she can inspect the cake and steal a strawberry off the top, not before you give her a light smack on the back.
“Eat your dinner first.” You chide, “thanks for the flowers, Keisuke.” His name sounds so familiar on your tongue, he melts at that moment, when he looks up to see you standing there, clutching the bouquet to your chest. It’s reminiscent of all those times he failed to make it on time to a date, offering a measly bouquet to appease your nagging, at the time he was just a stupid, shitty boyfriend. Being tired of college wasn’t a good enough excuse when he looks back at it. Keisuke was just an asshole who never deserved you in the first place.
“Just thought you’d like ‘em.” Keisuke nods, he takes the seat next to Hayako at the dining table when she forces him to sit. The cutlery and plates are already set, childishly printed napkins beside them, left over from Hayako’s birthday party. You pour him food, and you sit directly opposite him, though you never really meet his gaze.
Hayako fills up the silence easily, even when you tell her to chew her food before speaking, she continues to babble on about her day, about how happy she is to see the two of you together again. Keisuke thinks he’s been so selfish, to not meet up with you and his daughter regularly, the two of you have been too bitter to provide her with all she ever wants.
“Stay until I sleep, daddy.” Hayako begs, he wipes the chocolate icing off her face and pinky promises her that he’ll lay with her until she’s fast asleep. “And mommy.” She insists, so Keisuke’s stuck here, a few centimetres away from you. Only Hayako’s body separates the two of you, she’s fallen asleep but both of your are too scared to move.
Keisuke prods her face a little to check if she’s really sleeping, when it’s confirmed, he lets out a breath of relief and gets up. You follow after him, grabbing onto the hem of his shirt. “Keisuke, stay for a little.” There’s longing in your voice, and you refuse to look at him when you ask.
He tries to tell himself he’s going crazy, there’s no longing, he’s just crazy and lonely and regretful. “Okay,” Keisuke says dumbly, he sits on a leather sofa much nicer than the second-hand one the two of you once owned. The coffee table is a nice mahogany, the TV is bigger, you’ve done well for yourself and he somehow wishes he’d been there to see it.
You’re tipsy on wine, sitting close to him, knees tucked to your chest. Keisuke can smell your heady perfume, the softness of your natural scent seeping through as it’s worn off throughout the day. “I like Shuji, but Hayako doesn’t like him at all.”
“Hayako didn’t like any of my girlfriends,” Keisuke smiles, his daughter is the same as him, the way he hated anyone who tried to flirt with his mother.
“I want… I want her to feel better y’know, like I want her to feel like a normal kid.” You can’t find the right words, but Keisuke knows exactly what you’re trying to say. “I don’t want her growing up thinkin’ only me and you can be together, but I don’t want her feelin’ like we hate each other.”
“We don’t hate each other,” Keisuke cuts in, his brows furrowed, he was too quick with that. “I don’t hate you.”
“I hate you sometimes.” You say rather bluntly, wine has that effect on you, gives you loose lips. “She cried on her birthday, after you left, and I know it’s not your fault. But I fuckin’ hated you then.” There’s a shaky exhale that leaves your lips.
Keisuke hated himself then too, he couldn’t focus the rest of the day. Not for a minute. He doesn’t know what to say to you after that, staring at the ground.
“Keisuke,” you call his name, “can you kiss me?”
His heart drops to his stomach. He feels sick. Like this is some sick mind game. “____, you’re drunk. Let me get you to bed.”
“I want you to kiss me,” you tell him again, fisting the fabric of his shirt, and he wants to kiss you. But not when it’s like this. When you’re half out of your mind. “I wanna see… if it feels how it used too.”
Keisuke is a painfully simple man, he can’t resist you and can anyone blame him for that? When you gaze at him with such doleful eyes, shiny with tears, how is he meant to say no? When he kisses you, it’s tender, you don’t remember him being so gentle, so tame. He mellowed out with age, Keisuke regrets handling you so roughly when it came to affection. He doesn’t regret fucking you as hard as he did.
Softly, you whimper when his tongue runs over your bottom lip, sharp teeth ever so slightly digging into the plump flesh to tease you. It’s going further than it should, but neither of you can help it. “Keisuke,” you gasp when his big hands grip your hips, softer than he remembers. He pulls you forward onto his lap, his tongue follows the same trail Shuji’s did last night. He’s careful not to leave a mark, Keisuke’s grown up, he’s not as clueless as he was before.
“Baby, fuck,” he palms your tits, “did they get bigger?” It's such a juvenile question to ask, but it slips out anyway when he gives them another hard squeeze.
“I think you just missed me,” you giggle giddily when he lowers your shirt, unbuckling your bra with ease so he can take a hardening nipple into his mouth. The heat of his mouth makes you moan quietly, covering your mouth so you don’t wake up your daughter.
“I missed you so much,” Keisuke murmurs, the tip of his tongue swirling over your other nipple, he’s dragging out the foreplay much more than he ever did when the two of you were together. Keisuke’s grown up majorly and he wants you to know that. “Missed your pretty tits so bad.”
“That's all you missed?” You roll your hips into him, he tips his head back with a suppressed groan at the feeling of your clothed cunt grinding down into his bulge.
“Course not.” Keisuke lies you down on the couch, it’s significantly bigger than the old one, there’s no struggle fitting the both of you. “Missed this cute ass too.” He gives it a light squeeze when he slips your skirt off, tossing it down on the ground alongside your bra.
He’s still fully clothed, and you’re practically naked albeit your panties. Keisuke likes being like this. He hasn’t seen this sight in too long. He watches you squirm and complain for a minute or two, then he slips your panties to the side to give you what you want. His fingers run up and down your clit, thumbing your clit and tracing your tiny hole. He wonders how many times you’ve been fucked since he left, how good you’ve feel, if Shuji makes you cum as hard as he did.
“Fuck, Keisuke,” you rut your hips upwards into him, shamelessly needy.
“Shh, baby,” he hushes you, building you up to a pleasurable high with just two dexterous fingers on your clit, rubbing circles into the sensitive bud until you’re creaming. Your cunt clenches around nothing, and your eyes roll back into your head when he continues to pinch your clit, overstimulating you. “Look at that, my baby’s pussy still so easy, huh?”
The hand over your mouth muffles all your gasps of his name, your thighs tremble as he finally slips a finger into your tight cunt, curling it upwards and pushing into that spongy spot. He adds another to stop your whines of complaint. “You hear that, cutie? She missed me, yeah?” Keisuke teases when your pussy makes a filthy wet squelch with each thrust of his fingers, and the pressure is too much, it has you squirting all over his hand, a quick gush that covers him in your release.
You’re already spent by the time Keisuke unbuttons his jeans, he squeezes his thick cock, and you’re reminded of just how well he used to fill you up. Stretch your cunt out like no other man ever has. He’s the only one that has you creaming around his dick in seconds.
“I want it, Kei. I want it, please,” you blubber mindlessly, holding your legs to your chest as you beg him to fuck you. Shameless.
“Shit,” Keisuke curses, his cock oozes precum, a trail running down his shaft and trickling onto your already slick cunt. “All for me, ain’t it, baby? Pussy fuckin’ made for my cock.”
“All for you,” you repeat back to him like you’re in a trance, his tip taps your clit, it makes you twitch. Keisuke pushes in slowly, letting you get used to his sheer size. “Oh…” you let out a relieved breath, as if his cock is something that soothes a terrible ache. “Fuck me, Kei, please. Want you to fuck me.”
“I know, baby. I got you.” He kisses your sweaty forehead, easing in inch by inch until he’s sheathed inside you fully. Your body goes rigid, and you tense up, he just feels too good. “Wanted to take my time with you, angel, was gonna eat your pussy real nice. Just too slutty aren’t you?” He can’t stop staring at where the two of you meet, how your cunt takes him so well, greedily sucking him in like it’s begging for more and more.
You’ve gone completely slack, body shaking as he draws his hips back to slam back in. The wet slap of skin on skin, his balls hitting your ass. “Wait a second, baby.” Keisuke grunts, he lifts up into a low squat, your ankles behind your head as he continues to fuck into you. This position hits a new angle, and when he starts to rub your clit again, watching you squirm and writhe, it rewards him with another orgasm. Not only have you left a thick ring of cream around the base of his cock, but a short spurting stream as you squirt with every next thrust of his. He’s broken you. Or you just haven’t been fucked this well in years.
“No one’s been treatin’ this pussy right, huh? Don’t worry, baby, you’re feelin’ better now aren’t you?” He coos, hips circling as he feels the knot in his own stomach start to unravel. “Poor baby, so fuckin’ pent up, hm?” Keisuke continues to talk, his voice getting lower by the time he empties his seed into you. It’s the cherry on top. The gorgeous feeling of fullness, how warm his cum is in your cunt, you feel it trickling out, but you’re too tired to pay it any mind. The sofa is leather anyway, no dry cleaning needed.
“Shit, Kei,” you catch your breath and regain some kind of sanity, he’s scooped you up onto his lap, head buried in your neck like he doesn’t wanna let go. Shuji is in the back of your mind somewhere.
“____,” he says your name and you want him to take you again, you want him to take you in the bed the two of you once shared. You want him to fuck you in the morning before the school run, you want to kiss him when he comes home from work.
“Keisuke, stay with me tonight.” You plead, and like he said before, Keisuke’s a weak man. He can’t say no to you.
Keisuke carries you to bed, he lets you sleep on top of him, his hands running over your back. He thinks about what his mom said, she’s always right in some way. If only he hasn’t been so rash then maybe it could’ve worked out perfectly. There’d be no legal complications and no Shuji involved.
“I don’t… I don’t want you to go in the morning.” You tell him shyly, and it’s enough for Keisuke to know you wish for the same as him.
