Work Text:
It’s a normal, boring day when Mashiro asks an innocent, albeit ridiculous, question. “Wanna play truth or dare?”
“I dare you to do your job,” Kensei answers, not even looking at her.
“That’s not how the game works!” She looks at the paperwork she’s been avoiding for an hour, and puts her hands on her hips, undeterred. “It was my idea so I get to ask first! Truth or dare?”
“I don’t care.”
“Kensei!”
It is always easier to give in, and he sighs. “Fine. Dare.”
“I dare you to let me sit on your face,” she says.
Kensei chokes on his spit, coughs violently, and once he can breathe again, glares at her. “ What did you just say?” he manages, sure he’s misheard her.
Mashiro stares at him, unblinking, an eyebrow raised. “I said, I dare you to let me sit on your face.”
“The hell did you get that idea, Mashiro?” She isn’t above dirty jokes and teasing him, but she isn’t usually this vulgar. This reeks of outside corruption.
She tilts her head. “I heard the guys talking about it earlier, Kensei! Someone said you were yelling about something and then he said, “Lieutenant Kuna should just sit on his face.” She grins. “If it makes you stop yelling about everything it has to be good, right?”
It occurs to him that she has no idea what she’s asking for. There are two sides to her– sometimes she’s sweet and innocent, other times she’s flirty and teasing him. He always assumed she just randomly decided what personality she was going to have when she woke up in the morning, but in this case, he doesn’t know which Mashiro he’s dealing with, and her face is giving away nothing.
“It’s a sex thing,” Kensei finally says, and is immediately relieved when she gasps and her cheeks turn pink. “Now stop talking about it and do some work!”
For a moment he thinks it’s over, and then she pipes up again. “But I dared you!”
He recognizes the defiant tilt to her chin. She’s challenging him. Was this something she wanted ?
He knew he had been the subject of several graphic dreams of hers (and those were just the ones she’d narrated while sleeping at her desk) but he never actually thought anything beyond it. Mashiro had no shortage of admirers, he was pretty certain she could snap her fingers and most men in the Seireitei would come running. Himself included, apparently.
Still, the rational part of his brain (otherwise known as the part that still had blood in it) was telling him this was a bad idea. He didn’t want to be the pervert captain sleeping with his lieutenant.
But it wouldn’t be like that. This was Mashiro, and he couldn’t convince himself he didn’t want to. His attraction to his irritating, beautiful, infuriating, bubbly lieutenant was something he had kept to himself, but apparently he wasn’t hiding it well if his own men were joking about it. It was all the more reason not to. He didn’t know if he could have something casual with her.
This was making his head spin, and Mashiro clearly wasn’t pleased with his obvious reluctance, if her big sad eyes were any inclination.
He was going to have to take an ice cold bath after this. He had to get her to stop looking at him like that. “I dared you to do your paperwork and you haven’t done that yet.”
“I’ll do it all right now, and even some of yours too,” Mashiro counters immediately.
He actually has to bite back a laugh there. Mashiro, volunteering to do extra paperwork. The end of the world was near. “Mashiro…”
Mashiro sticks her tongue out. “Oh, fine, whatever! You’re just a big chicken.”
“I am not!”
“Then why don’t you want to?” Mashiro whines.
“You probably wouldn’t like it.” (He is actually certain that she would like it.) All he gets in exchange for that is a soft humph, which is fine. At least she’s not yelling, or worse, pouting. Or some noisy combination of the two that only Mashiro can achieve.
Instead she goes for a different tactic, one he is less prepared for. She shrugs. “Whatever, forget I said anything. You’re probably bad at it, anyway,” she decides. “Wimp.”
That did it. He was going to shut her up once and for all. “All right, fine,” he finds himself saying. “But later. I’m not doing it here. And you better do all your paperwork too!”
“Really?” Mashiro’s eyes are huge. Clearly she didn’t expect to win that easily. “You gave in fast. You wanna do it too, don’t you, pervert Kensei?”
“Don’t turn this around on me,” he says warningly, brandishing a fist at her. He’s rock hard and he really just wants to fuck her right here on his desk, but forces those thoughts to the back of his mind. “Just come over later.”
Mashiro’s eyes have somehow gotten even bigger, and she nods so fast her head is a green blur. “Okay!”
“And you better not say shit to anyone. And don’t get any ideas about this either, all right?”
She rolls her eyes exaggeratedly. “Oh my gosh, Kensei. What am I gonna do, stand outside with a sign? Do a tenteikura? Hey everyone, Captain Kensei Muguruma stuck it to me good last night!”
He can’t get up to punch her and there isn’t anything particularly heavy on his desk he can throw at her, so he just glares at her and goes back to ignoring her, but he’s well aware despite the shocking sound–or complete lack thereof– of her actually working quietly for once, she keeps looking over at him. He hedges one glance at her, and she blushes and looks down at her work again with a smile on her face. His neck burns with embarrassment and he resolves to ignore her for the rest of the afternoon.
He goes straight home, gulps down a glass of sake and after a moment of thought, goes for a second. The alcohol scorches a path down his throat to his stomach.
It’s a stupid dare, not a blood oath. He can tell her to go away and he’s not going to do it.
She would never let him hear the end of it.
And he wants to do it. He’s actually thought about doing it before. As annoying as she can be, they’re good friends and he cares about her. That doesn’t stop him from being attracted to her– if anything, the connection makes him even more attracted to her.
His erection twitches in his pants and he considers giving himself a bit of relief before Mashiro arrives, and the thought doesn’t live long in his head before he is pulling his pants open, wrapping his hand around his erection and palming himself. Mashiro is front and center in his mind, which has happened before, but he doesn’t remember it ever being so vivid. It’s like she’s in the room with him.
There was a soft tap on his door, and he jumps to his feet, stuffing himself back in his pants hastily and shoving the door open. Mashiro greets him with a bright smile. He notices she’s changed out of her shihakusho into a pretty pink yukata. He can also tell despite her bright eyes and wide smile, she’s nervous.
Well, they have that in common. Just seeing her is making his heart race.
“Whatcha been up to?” she asks, linking her hands together and peering curiously around his house, as if expecting him to have changed anything from the last time she was here.
“Since I saw you an hour ago? Nothing.” He offers her the sake with a raised eyebrow and she accepts, drinks it immediately. He can’t tell if she knows what he was just doing, but she’s giving him the eye and there’s a smile on her lips.
He’s just overthinking everything. Which is smart, as Mashiro thinks of nothing, and someone has to be the sane one.
She is still looking up at him expectantly, and it occurs to him that he is going to have to be the initiator here. With a sigh he takes Mashiro’s cup from her, places it down on his table, and grabs her wrist. She lets out an excited gasp. “Are we starting already? Are you taking me to your bedroom?” she asks.
“No, you idiot, I thought the patio seemed like a good spot. What do you think?” He practically drags her to his bedroom, shuts the door behind him, and makes sure the windows are closed.
Mashiro grins up at him from where she has flopped back on his bed, sprawling out like she belongs there. “So, are you going to ravish me now, or keep me waiting?” she asks playfully, batting her long lashes at him. “Any time you’re ready!”
She laughs again when he blushes, and he shakes his head. “Shut up and take your clothes off, idiot. Start there.”
That makes her giggle as she jumps to her feet and reaches for her obi. “Look, Kensei, I’m doing what you said to do for once! Yes, sir, Captain!” She salutes him even as she slides her yukata off her shoulders.
Some incongruous part of him notes that is the first time she has ever actually called him Captain, but his mind is otherwise distracted because she is quite literally stripping in front of him, completely unabashed as her yukata pools around her ankles. She even takes her sunglasses off the top of her head and drops them on the pile, and smiles, posing with her hands on her hips. “See something you like, Captain Muguruma?”
“Stop calling me that.” The last thing he needs is to get an erection every time someone addresses him by his rank, but in all honesty she’s even more perfect than he let himself imagine. She was incredible. Her tiny waist, curvy hips and thighs, and her full, perky breasts are burned into his mind now. Her pale skin looks soft and smooth. He wants to put his hands and mouth on every inch of her.
Mashiro cups her breasts, looks up at him. “Hopefully my boobs are big enough for Captain Muguruma’s inspection. I wouldn’t want to disappoint my captain!”
She’s teasing him, and that snaps him out of his lust-crazed stupor. This is the stupidest thing he has ever agreed to. His erection feels like an iron spike in his pants as she sits back down on his bed, kicking her legs, and looks up at him expectantly. “Your turn. Come on, Kensei, I wanna see you naked!”
“I don’t have to be naked, if I’m just…” Her pout was immediate, and he let out a growl before starting to pull off his own clothes, too. This is the weirdest fucking day of my life.
He whips his robe off his shoulders, then shoots her a cocky look. He doesn’t miss the way her eyes widen at the sight of his bare chest, or the rosy flush that blooms in her cheeks. His erection throbs painfully, and it dawns on him that there is no way of hiding his arousal once he took off his pants. He considers coming up with an excuse to leave his pants on, but Mashiro squashes the notion by pointing to his lower body, snapping her fingers. “Come on,” she whines. Shit. This woman was going to be the death of him.
The second his pants hit the ground, Mashiro’s breath hitches, but she doesn’t comment on the erection trying to tunnel its way out of his underwear. His underwear goes last, and he stands there naked in front of her.
“There, are you happy?” he asks, because she has yet to say anything. She was staring at him, eyes wide as she looks his naked body up and down, obviously appreciating the view.
“Oh, wow.” Mashiro hops up to her feet, reaches for his erection and he inhales, both surprised and relieved when she wraps her soft hand around him. “Is this because of me?”
“You’re naked and you’ve been talking about this shit for hours now. What do you think?”
Mashiro has never met a rhetorical question she doesn’t want to answer, but in this case she doesn’t seem to care. She’s pumping her hand, gazing up at him, looking at his face to see his reaction. “Is this how you like it?”
In response he covers her hand with his, adjusting her grip to be a bit tighter. “Like that?” Her hand is so soft and warm. He nods.
Mashiro’s eyes sparkle, and she sits on her knees on his bed, putting her right at eye level with his erection. “Is it okay if I do this?” She looks up at him, eyes bright even as her tongue traces a line up his cock, and he can’t stop the groan that comes out at the sight.
“I’ve never done this before,” she admits. “So tell me if you don’t like it, okay?”
He wants to tell her that there’s (probably) nothing she could do while she’s on her knees in front of him that he wouldn’t like, but there’s no need. She licks her full lips, leans forward, opens her mouth and sucks him in, running her tongue over the tip of his cock and slowly working her way down.
It feels incredible and he slowly threads his fingers through her hair, holding as still as he can. Mashiro makes a contented sound, sucks hard. He can see her shifting impatiently on the bed and he can tell she’s as horny as he is, as she attempts to take him even deeper in her throat.
He barely recognizes his own voice. “Fuck, Mashiro.”
She looks up at him, her eyes sparkling with excitement, and he almost blows his load right there at the sight of her face. She looks determined to get him off, and something about seeing that same determined look he’d seen so many times on her face now, with his cock in her mouth, is so fucking hot he can't take it. Something about his reaction gets her even more worked up, as her tongue works over his head. She moves her hand, scoots closer, tries to take him deeper, but when he groans and jerks his hips she coughs and pulls back, sputtering a bit.
“Fuck. I’m sorry,” he says quickly, stroking her hair apologetically as she makes a series of faces. “You, uh, okay?”
“You’re really big,” Mashiro pouts.
He snorts. “Yeah, well. A normal woman would be into that.”
“Are you really making fun of me with this in my face, Kensei!? This was supposed to be about me,” Mashiro complains, standing up and giving him a small shove. “How did you turn this around on me, you big pervert?”
“I didn’t do anything, you just started blowing me! I wasn’t about to stop you!”
She traces her fingers over the muscles in his chest. “Well, you just seem so tense. I thought it would relax you a little. And I liked it too.” She looks up at him. “Want me to try again?”
“Later.” He lets out a deep breath and turns to her. “Alright, come on.”
Her confidence seems to waver a bit. “Like, right on top of you?” She worries her full bottom lip between her teeth.
The thought of tugging that lip between his own teeth occurs to him, and he bites back a groan. “That’s the idea, yeah. Unless you don’t want to.” It would be just like her to get him all worked up for nothing, but she suddenly seems too nervous for this to be a prank. He grabs her shoulders. “Seriously, Mashiro. I’m not gonna be mad if you change your mind.”
Mashiro stares up at him. “Change my mind?”
Before he realizes it she’s throwing her arms around his neck and kissing him. It’s almost funny– she’s given him a blowjob, they’re naked, yet this is the first time they’ve ever really kissed– but he supposes they’ve never been the type to do things predictably anyway. Her lips are impossibly soft against his and she’s surprisingly hesitant for someone so eager.
It doesn’t take him long to take control of their kiss, deepening it, and she yelps against his mouth when he cups her ass and lifts her up against him. Instinctively, she wraps her legs around his waist, her arms around his neck, and holds on tight as he lowers them both onto his bed.
Mashiro’s curiosity is nowhere near sated by one kiss, and she pulls him closer by his shoulders, her hands dragging down his back and exploring his muscles. He assumes it’s okay to touch her, too, and gradually moves his hands down from her face and neck to her breasts.
She gasps out loud when he does, and that just encourages him all the more. He squeezes her breasts, pinches her nipples, rolls them between his fingers. She’s moaning so loudly he would be worried about his neighbor hearing, were it not his neighbor underneath him right now.
His hand moves between her thighs, and she whimpers, parts her legs to give him access. She’s so sensitive, so eager, it’s not a surprise that she’s dripping wet already. He strokes her, watching her face to gauge her reactions, and she’s squirming into his hand.
“You are so fucking wet,” he tells her, dragging his fingers between her folds. She moans in response.
“Then do something,” she pleads. It’s so cute he’s pretty sure his heart skips a beat.
He leans down, kisses her again. “I’m gonna do a lot more than something. ” He nips at her ear, making her gasp. They both groan when he slowly eases one of his fingers inside her, and she lets out a long moan, clutching his shoulders.
“Fuck, you’re tight.” Imagining how she would feel around his cock has him bury his face in her neck, breathing in her scent. He finds her clit, rubs it with his thumb as he sinks his finger inside her, and she’s practically coming undone just from what he’s doing.
“I didn’t think you’d be this easy,” he teases, his voice low in her ear.
“K-Kensei,” she whines, grinding her hips into his hand. “I– I want more.” Her eyes are glazed as she grabs his face, kisses him again. He slants his mouth over hers, swiping his tongue over her full bottom lip, and she opens her mouth under his, letting him deepen the kiss, raking her fingers through his hair.
Remembering her request for more, he adds a second finger and thrusts, curling his fingers, immensely enjoying the way she’s writhing under him and moaning his name. All he really wants to do is line his cock up and slam inside her, but he remembers what he promised to do for her in the first place. She’s supposed to be on his face right now. He dismisses the thought, resumes fucking her with his fingers. He’s pretty sure she’s not going to be upset if he makes her come twice in a row.
“Wh- why did you stop?” Mashiro gasps, her chest heaving. Rather than answer her, he just kisses her once before moving down to her breasts, taking a nipple in his mouth and biting gently. He feels her muscles spasming around his fingers as her back arches, and she’s coming undone beneath him, making the most arousing sounds he’s ever heard.
Mashiro gasps breathlessly, her fingers raking through his hair to keep his head against her chest. He kisses her breasts again, rather reluctant to break the hold he has on her, but he has a job to do. He slowly pulls his fingers out of her, which makes her whine and pout up at him.
He snorts, shakes his head. “Don’t give me that look. I’m not done with you.”
Her cheeks flush and he is briefly stunned by just how pretty she is. He’s always known this, has thought it since the day he met her, but she’s literally naked in his arms and it’s at the front of his mind. He pushes her hair from her face.
“Wh-what?” She asks breathlessly. She doesn’t seem to know what planet she’s on at the moment, and he can’t help but feel immensely proud of himself. He kisses her again, and she responds immediately, already squirming underneath him again. She arches her back, pressing her hips against his erection, and they both gasp at the sudden contact.
“Kensei,” Mashiro whines pleadingly. He nods, squeezes his eyes closed as he slowly, teasingly drags the head of his cock against her wet slit, and she whimpers and writhes under him, her nails digging into his biceps.
He’s starting to think he might be losing it a bit himself. He pulls away. “Want to get on top of me?”
She nods immediately, gets up on her knees. He grabs her hips and basically pulls her towards him, nudging her legs apart. Even he’s rather surprised at the urgency he feels, wanting to get his mouth on her immediately. She whimpers, positioning herself on top of him.
He grabs her thighs, looks up at her. “If you don’t like something, tell me.” He digs his fingers in her skin for emphasis. If he’s doing this, he’s doing it right.
Mashiro nods hurriedly, squirming impatiently. His eyes roam over her body shamelessly. Their eyes meet again and he pulls her body closer to his face by her hips. He nips at her thigh before he licks her wet center, and he hears her sharp gasp, feeling her entire body jerk. Her reaction encourages him to do it again, harder this time, lingering on the little spot he knew would make her crazy.
“Kensei!” she gasps, before clamping her hands over her mouth.
He gives her ass a pinch, which makes her yelp. “Don’t do that,” he orders, voice slightly muffled. “For once I wanna hear every noise you make.”
She nods hurriedly. The vibration of his voice made her hips twitch and her grip on him tightened. “Kensei, it feels so good,” she whines. She sounds more than a little breathless, and he feels a surge of pride shoot through him.
“Yeah?” He grips her hips tightly and began to suck on her clit. She gasps and bites down on her bottom lip, completely lost in pleasure. His hands travel up her body, leaving a hot trail where they pass.
He sucks hard on her clit before running his tongue over her entrance, licking her again, lingering on it. He pushes hard inside her with his fingers, making her moan loudly. Mashiro’s body jerks, and she lets out moans and gasps of his name as she rides his face.
He sees her shut her eyes tight, feels her pussy clenching around his fingers, and then she’s coming, her entire body clenching up as she bucks her hips against him, and when she comes back to her senses, her body is a shivering, panting mess.
The muscles in her thighs are still jumping, and she wriggles her hips shamelessly against his face, riding with the last spasms of her orgasm. She is still panting when he sits up, more out of necessity for breath than any actual desire for her to move, and he glances at her.
“Fuck. Are you alive?” he asks, unable to keep from chuckling at her. She looks up at him, her eyes huge.
“That… was amazing,” Mashiro manages, shaking her head. “Wow. Are you just really good, or is it always like that?”
He furrows his brow. He’s aware she wasn’t familiar with the expression, but the way she’s talking makes him curious, and he realizes what she’s asking. “No one has ever done that for you before?” he asks incredulously. He is irritated on her behalf.
Mashiro shakes her head, looking shy. Her cheeks are pink. “Why do you look mad?”
“I’m not mad. Not at you, anyway. You just wasted your time with idiots.”
Her eyes are teary and for a moment he thinks he made her cry, but she tackles him and kisses him again, straddling his hips and letting out a moan when he shifts underneath her. His cock nudges her again and she whimpers, grinds her hips against him. He closes his eyes–it feels amazing, and if she doesn’t stop, he is going to fuck her.
“Mashiro,” he manages, gripping her hips, stilling her immediately. “Hey.”
“Sorry.” She blushes again. It’s so cute he sighs and pulls her in for another kiss, and they just make out for a while until the need to breathe separates them. They both lie there tangled together, catching their breath.
It occurs to him suddenly that she is literally naked in his bed and he’s given her two orgasms, and this has happened only because she dared him to do so. Not that he’d ever demand she return the favor–but maybe she wants to. He blurts it out before giving it a second thought. “Hey. It’s my turn.”
“Turn?” Mashiro asks, looking confused as she peers up at him.
“For the stupid dare thing. I did what you said, so now it’s my turn.”
“Okay,” she says, blinking up at him. “Um— I’ll go with a dare, too?”
Either way he was going to say the same thing, but he’s glad she chose correctly. “I dare you to fuck me.”
She lets out a delighted gasp and straddles him, and they both groan as she slides down him. He lets her ride him for a few minutes, immensely enjoying the view of her bouncing and grinding on top of him, and he reaches up to cup her breasts, pinching her nipples and making her moan again. Her fingers dig into his chest.
He’s not going to last much longer and he very, very much wants to fuck her, so with that in mind he grabs her ass, rolls them over and traps her underneath him. Mashiro lets out a squeal, and he pounds into her relentlessly, giving her his full length with each thrust. She’s crying out underneath him, and it isn’t long before she’s coming and he’s following her over, spilling into her and collapsing with a groan.
There is a long, companionable silence, with both of them trying to catch their breath. She’s still in his arms, her breath tickling his shoulder. He is content to never move again for the rest of his life.
“I can’t move my legs,” Mashiro sighs. The blissful tone of her voice makes him feel an overwhelming sense of pride, and he tightens his arm around her, kisses her hair.
“Stay here then. Just for tonight,” he adds immediately, when she looks up at him with excited eyes.
She snuggles close to him, her head pillowed on his shoulder. He feels her hand on his chest.
"Hey Kensei?"
He manages a sleepy groan.
“I…”
She doesn’t say anything else, so he nudges her. “What?”
She’s silent still, and he feels her soft breath tickling his chest. A loud snore escapes her lips.
He sighs and pulls her closer.
