A/N: Please note this is mostly a chapter of PWP, so it is mature content.
"This water is too hot," Eren complains, his right foot inside the bubble bath with his left being used to keep his balance on the outside.
"Well, you weren't really invited in the first place," Mikasa replies, splashing water up her arms. Her short hair is left down, its tips lightly skimming the waters edge as she leans down to hide more of herself underwater. She picks up bubbles between her fingers and blows, watching them fly off her fingers and land back into the water. With a weary expression she adds, "Are you sure there's enough room for you in here?"
"We'll make it work," Eren replies, seeming unbothered by the clear implication that his girlfriend wants to bathe alone. He eyes her for a moment before glancing at the remaining space. He deduces one clear, obvious fact: He will not fit in the tiny space that is left. He also, therefore, concludes there is only one viable option left: He will simply have to place her on his lap.
In an attempt to be nonchalant that does not fool Mikasa, Eren removes his foot and casually walks to her side of the tub. He does not miss the way that, though her body has not shifted, her eyes certainly have; from her peripheral vision, she's clearly watching him closely. For a moment he thinks she's being rather selfish—he shares everything with her, could she not share her bath with him, just this once? But the thought passes quickly as he attempts to be suave and sleek by grabbing her under her arms to lift her.
It is unfortunate that she weighs more than he's calculated and she plops back down into the water with an irritated, "What the hell, Eren?"
"Mika," he whines, leaning close to her ear, still outside the tub. "Sit on my lap?"
"I hate that nickname and no. I told you earlier I didn't think there was enough room." She's still playing in the bubbles and he realizes that she's creating rather large, puffy, white breasts for herself. He forces himself to bite the inside of his cheek to keep from laughing. While he certainly adores her smaller breasts, he has to admit the thought of her a few cup sizes bigger is rater titillating.
"Please," he begs, leaning in close to her ear and lowering his voice in what he hopes comes off as seductive. "I'll make it worth it, I promise."
"You do realize the last time you said that you came before you even got it in?" She adds extra padding to her fake breasts. "So your offer doesn't really hold much credibility in my court. Sorry."
"That sounds like a very insincere apology. Anyway, you'd been teasing me all night, that wasn't my fault." Eren feels the pout forming on his lips before he tries once more, lips curling before he's even spoken because he knows very well she'll understand his next reference. "And I'll do that thing I haven't done in a while."
Her ears perk and she turns to him, intrigued, bubbles forgotten. He can see her debating if receiving something she particularly likes is outweighed by her extreme dislike of sharing her bath.
"Fine," she says after a moment. "I'm holding you to your word." Which she'd already said she discredited, but he had more to lose than her by not following through. She sighed before standing up, careful to avoid spilling water over the edge (because, no doubt, the entire cleanup would be left to her per usual) to make room for Eren.
"Cross my heart and hope to die," he answers before sliding in to where she'd been moments before. He spreads his legs a bit to make room for her, though the tub is so cramped he figures he may as well have not tried at all.
It takes some time before he feels the stiffness ease from her back, her body taking it's time to melt against his with help from the warm water; he can barely feel her skin against his, though she's flush against him. She sighs once more, though this time from clear contentment and, as her breathing begins to even out, he realizes she's falling asleep—that certainly won't do. He wiggles his hips beneath her just so, knowing she'll feel him against her backside; he's not yet hard but he knows that's certainly subject to change.
"Can't I have a moment to enjoy the water? This is what I was going to do before you decided to invite yourself." Her tone holds no real contempt for she's far too relax, her body lazily splayed out above his in the water. She wants to turn and curl into him, let him wrap his arms around her, but then her legs will be above water, and she'd prefer to be warm than held.
"No," Eren replies, glancing around the dimmed bathroom. "You have enough candles in here to set the entire apartment on fire if one fell. Why do girls need candles to take a bath, anyway? Can't you just turn on the light?"
"You're really ruining my moment." More words are poised on her tongue till she realizes one of his pointer fingers is idly drawing circles around her breasts, tracing their outline, occasionally going upwards to gently tweak at her slowly hardening nipples.
She closes her mouth and once more sighs, murmuring, "I hope you're not expecting me to do all the work."
"Only some," he promises, unable to keep the playful tone from his voice. He doesn't miss the way her body softens above him, sinking more and more into him, into the water. The hand tracing her breasts makes its way up, up, up, till he's beneath her chin and gently he pushes it upwards; she follows the indirect command easily, tilting her head to the side, curious as to what his intentions are. When his head leans down, hair tickling her cheek, she smiles; it's so subtle he almost misses it.
When his lips connect with her neck, he purses them, kissing the vein beneath and whispers, "Jugular."
"Didn't we agree you'd leave being a doctor at the hospital?"
"Hush," is all he says before kissing the spot once more. His lips slide over a tiny bit and he places another kiss down. "Carotid."
As his lips kiss around her neck, he stops at the base behind, adds, "Spine," and continues his exploration.
These are parts of her body he knows well—he's had four years to learn them, after all—but every now he tries to look at her with new eyes and a fresh perspective, tries to see her in new ways he hadn't seen before. When his lips touch the side of her head he murmurs, "Temple." He glances down and sees that her eyes are half open, a sure sign of her contentment.
She can't see his hands beneath the bubbles, can only feel when they begin to trace new circles around her bellybutton. She wills him to go lower, to tease her just a bit down there, but instead his fingers inch down to scrape gently at her hipbone, his nails digging into the skin. In easy, languid motions his fingers continue their voyage, traveling to skim over the top of her thigh; his body leans forward to reach farther down to her knee before scraping back up with blunt nails.
"Tease," she breathes, intentionally mimicking his earlier actions by rocking her body against him. She's certain he's noticed he's hard by now, stiff between the cheeks of her bottom; he'd have to be an idiot to not notice it about himself. But, much to her surprise, he's ignoring himself (for once, she notes with a bit of selfishness) in favor of her. His fingers inch back up and ghost over the part of her she wants touched most; it's smooth and soft, waxed only a few days prior.
Eren loves all parts of Mikasa, even her temper and bouts of moodiness, but loves her most when she's malleable putty in his hands. He knows what she wants and smiles as he presses his mouth to her ear, his thumb caressing her for the briefest moment as he whispers, "Clitoris."
There's a hitch in her breath, a quick jerk of her legs that causes water to slosh over the edge. The touch is far too light and airy for her liking. "Don't be an ass." His hands are wandering around, touching the inside of her thigh but never straying close enough to where she's slowly starting to ache.
Eren doesn't attempt to resist the smile that spreads wider yet over his face and he presses a kiss to the side of her lips. It's satisfying to know that with her body above his, her back and ass pressed firmly into him, is still trying to arch back and guide him. He's hard—ridiculously so, in fact—but it's always quite entertaining to tease her till she's near begging.
"You could say that nicer, you know…" His fingers skim closer and he grazes her outer lips between her thighs and says, "Labia."
"It's really not a turn on with you—" Another sharp intake of breath, a thrash of legs.
"You were saying?" He assumes it's the fingers he's slipped inside her that's caused her reaction and he laughs quietly to himself. "You know, I'd say you seem pretty wet, but…"
"Not funny." Her voice attempts to regain it's composure but the intent is lost as squirms against his fingers, aiming to get them deeper. Instead, she feels him curl his fingers upward and his thumb begin to rub in gentle, languid circles against the small, sensitive nub that draws more breaths and soft, restrained moans from her.
She knows he's now doing it primarily for one reason, and is hardly surprised when, after a few minutes of her writhing against him and his fingers, he says, "I think you're ready now…."
"No," she replies, saying this because she knows it means moving and therefore causing some of the warm water to no longer be around her. (If she's honest, she's more than ready for more of him and not just his fingers.)
"Oh well, I'm not really asking." With an easy, fluid motion he removes his fingers and props her up; the cold air hits her hard and her body stiffens. Eren does not miss the opportunity to tweak her nipples, chilled from the air. She's still not facing him, though it hardly matters, for he's already got a position in mind sure to benefit them both.
Mikasa rolls her hips against him once more, growing impatient from waiting, wanting to be back in the water once more. She doesn't particularly need to be told what to do, already aware of the position he's trying to maneuver her in to. When she feels his hands beneath her bottom, lifting her up, she complies and helps with a loud, intentionally dramatic sigh.
"Remember what I promised?" He shifts himself beneath her, positions her above him. "Now it's okay…Go down slow."
In an act of what Eren assumes is defiance, Mikasa does anything but, initially sliding down slow to assure he's in properly before quickly lowering herself the rest of the way. He wants to almost be mad—it feels so good when she goes tantalizingly slow—but he can hardly be upset; he's all the way in when she rolls her hips, rocks against him. She knows perfectly well how to make him cum fast and it's obvious to him it's her goal—make him cum quick and pull out to get to her favorite part. Instead, he holds her hips and pulls her back with ease, lowing her back to his chest, mindful to stay inside her.
"Better." It's easier to toy with her chest this way, both of his hands reaching up to cup a breast, kneading in an even rhythm. "Move your hips a little…"
He knows she wants to retort with a comment, though he supposes the way he pinches a nipple—firmly and with enough pressure to cause a whine to seep past her lips—has something to do with her change of heart. She rolls her hips, mindful to go slow to keep him in (they last time they'd tried this position in bed, he'd repeatedly kept sliding out, much to his dismay). For the moment, he lets her take control, his head falling back against the walls of the shower behind him, hands still on her chest.
When her hips start making small, concise circles that eventually fan out into larger ones, he thinks that this is certainly how her athletic body should be used more often; it's always so much more fun to worship her up close than afar. His hips rise up, wanting her to cause more friction, but she's going achingly slow now, a contradiction to her earlier actions. She knows what she's doing and certainly is not going to let him off easy.
"You seem like you're getting there," she sighs, reaching to a hand on her breast and bringing it down to caress the small bump that sent tremors through her. She grabs the other and placed it firmly on her hip.
"Would be there sooner if you'd go faster," he replies, obliging her silent request, his thumb pressing down in waves of fast, slow, fast, fast, slow. He knew he was doing it right when her pace quickened, when he could feel the tightness building in his abdomen. The pressure eases only after he's released, quite loudly and with her name parting from his lips repeatedly. The hand against her hip grips it tightly, nails leaving crescents against her skin. She's stopped moving, beginning to rise herself off of him when it appears he's coming to once more.
Eren can't help but notice the show she's making of turning around to straddle him, a contented, pleased smirk on her face. She leans down to kiss him, words a whisper as she says, "Don't forget your promise."
He takes the chance to meet her halfway, giving her a kiss much too chaste for their current position. "You're going to have to get off of me and out of the tub. And don't grab a towel."
She didn't make any noise of complaint, though Eren suspected it was due mostly to her finally getting what she really wanted out of the night, out of his promise. She slid off of him easily enough, careful as she placed a foot on the rug near the tub to avoid slipping. When she'd stepped out she turned to look at him expectantly, watched as he pulled the plug up to drain the water. When he finally turned to look at her, a telltale smirk now on his face, she didn't both to try to hide the flush that rushed through her—it has certainly been far too long since he's looked at her that way.
He steps out of the draining water, his feet landing on the mat where hers had been previously. He pulls her close, flushes her body against his, and takes her hands into his. "I'm going to put your hands on the rack. Don't move them, or I stop. Deal?"
"That wasn't what we agreed on earlier." It bothers her the way her voice comes out whinier than she'd intended.
"You'll have to trust me, then, won't you?"
Their bathroom is far too hot and small for any actions beyond its intended purpose, but those small, minor setbacks don't prevent anything: Mikasa holds onto the bar as instructed, waiting with false patience for Eren to hold up his end of their bargain. Eren doesn't bother to attempt to hide the smirk on his face—with her body and gaze facing the wall and him behind her, he knows she won't see it, anyway.
"I can now determine with my intelligent mind that you are, in fact, wet," he teases, slipping a hand between her legs.
"We just got out of the bath." It's a point she feels compelled to make.
He assumes her tone is meant to sound stern but finds it holds no real contempt; she's melting into his hands and arching willingly into his palm, into the fingers that are making their way inside her.
"Remember the last time we did this you broke the bar from holding it too tight?" His tone is mildly conversational and it irks her—he should be focusing more on his fingers toying with her than holding a conversation.
"I forgot, but thanks for—ah!—reminding me," she replies, her skin flushing as she feels him part her cheeks. She knows what's coming—he promised her favorite thing, after all—but the act still causes her mild embarrassment; his mouth between her legs is kryptonite.
"My pleasure," he replies, leaning in close to her, his tongue parting out to swipe for a second. His lips curl once more. "Va—"
"You say it and I'm going to punch you into the wall."
He laughs, his mouth so close to her opening she feels the vibration. Shivers tickle her spine and she doesn't realize the way she leans back into him more, grazing his lips. She thinks for a moment he'll make another irksome comment, instead finding herself pleasantly surprised as he tongues her once again. Years of practice between the two of them have made them sufficiently adept at pleasing the other, his tongue tracing a memorized path, methodically (expertly) teasing her outside before snaking inside.
Mikasa's aware her voice is rising, that sounds she wouldn't normally make are leaving her throat, but she doesn't quite care and besides—the more Eren thinks she's appreciating it the more enthusiasm he'll put into it.
It's with a curve of his tongue inside her and a soft caressing outside that builds her up, up, up; her eyes close and her grip on the bar tightens, the skin on her knuckles whitening.
"Eren… Close…" Her back arches, attempting to fall more into his mouth.
"Then cum." His voice is a notch above a whisper, a hum intended for her to feel; his lips purse and he sucks lightly, feels her body tense and unwind within moments of each other. Her voice—his name—echoes, the spasms from her body almost unnoticeable. (She's sure she hears him say climax in there somewhere, but she can't be so sure.) When her knees grow weak he catches her in his arms, peppers her face with kisses.
He can feel her body becoming heavy, lazy from the orgasm, and he sets her down to retrieve a towel from the rack she'd been holding, laughing at the way she's unstable on her feet for a brief second. He wraps it around her shoulders, more to keep her warm than dry, as most of the water from their earlier bath has come off. He reaches behind her knees and hoists her up—not an easy task, as her muscle mass certainly outweighs his.
"Where are we going?" It's the first sentence she's spoken to him after, said in a drawl that indicates she wants nothing more than to go to sleep.
"Think it's time for bed," he replies, carrying her across the hall and into their room.
"Wash your face first, you're all dirty again…"
"But we didn't really wash in the first place…" He feels her nuzzle into his neck and knows she hasn't heard a word.
Before he sets her down he feels her lips against his neck, biting with a surprising amount of care; he knows there will be a dark bruise later he'll have to make an excuse for, but it's rare for her to intentionally do something so obvious. He can't help but think she must be thoroughly pleased to show such affection. She's naked still when he lays her down, though by the time he's come back from grabbing her a pair of pajamas she's already asleep, tucked soundly beneath their comforter.
He sighs before setting the pajamas on the nightstand and leaning down to kiss her. She stirs for only a moment, her head turning away. She doesn't feel him leave a trail of kisses down her jaw and neck, stopping only at her chest to murmur, "Heart."
