Chapter Text
When Rei wakes from what must have been either an early afternoon nap or a full night of sleep, limbs heavy and eyes still unwilling to focus, he can feel a presence that wasn’t there before.
Wataru has wrapped themself around him like a constrictor, both legs and arms clinging around him and holding tight, their head resting against his chest. That he hadn’t awoken until now speaks to just how deep he must have been sleeping beforehand. Rei closes his eyes again and takes a deep breath, sending a brief prayer of hope to please let this be a sign that he’s slept through most of the night.
He’s uncertain when exactly Wataru crawled into bed with him. When he’d first laid down, neither them nor Tenshouin had gotten back.
Not that he’d expected Wataru here at all— their presence in this dorm room, albeit more and more frequent, continues to be contingent on Shiratori-kuns absence and Keito’s willingness to turn a blind eye. The fact that neither Wataru nor Tenshouin have begun to test the limits of their dorm supervisor’s leniency on sharing beds speaks to something. Rei doubts it’s maturity, but it must be at least something approximating it.
That Tenshouin and Wataru would be careful around Shiratori and Keito does not mean they are as mindful with him, though. Being in the same room as both of them can, at times, feel not unlike being a small bird trapped between two very playful cats. Or, perhaps, in his case an injured old bat, unable to spread his wings to flee their attention.
With Wataru very snug around him, it’s easy for Rei to disregard any worries about what their presence might mean for any future mindgames, from either his partner or roommate. For now, he’s comfortable, and Wataru’s breathing is even and calm.
When he rouses from his doze again, it’s because Wataru is shifting in his arms, turning around so their back is against his chest. Soon, Rei finds himself twisting his head to avoid breathing in the few loose hairs not caught in the braids they usually wear through the night.
“Mmmh, good morning Rei”, Wataru, who must have already been awake or waking up, mumbles, the smile audible in their voice.
“Morning, Wataru.” Is it morning then? Rei attempts to turn so he can squint at the alarm clock, but finds himself unable to do so fully, with the weight of Wataru’s torso on his arm. The room is still mostly dark, but there are hints of pale light coming through the blinds. Morning, then. So he did sleep through the night.
“I took some liberties when I arrived here,” Wataru continues. They’re still quiet, likely because neither of them can see Tenshouin right now to confirm whether or not he is still asleep. Rei had gotten into the habit of sleeping with his back to the divider very early on. “I hope you don’t mind my decision to sleep with you.”
“Your presence is always welcome”, Rei asserts and holds them a little bit tighter to reassure them of that point, even if it means breathing in some more hair.
“How kind”, Wataru hums, and wiggles backwards, pressing themself closer against Rei. Which—
“Wataru”, Rei groans, a mild warning.
“Hmmm?” They arch their back, slightly, and Rei has to pull his own hips back further on the bed to escape the pressure.
“Tenshouin-kun is right there.” Truthfully, Rei still doesn’t actually know if Tenshouin is right there, but it feels like a safe assumption to make.
Wataru, seemingly entirely undisturbed, does an impressively quick turn so they can face Rei again, and swings one leg over his hip, holding him in place. “Exciting, isn’t it?”
Mercifully, they refrain from grinding up at Rei so the groan he lets out at their response is painted by nothing but his own exasperation. Tenshouin knows. Must know. Has to know. Likely suggested tonight's entire arrangement in the first place. Or maybe it’s something Wataru and Tenshouin cooked up together the evening before.
Rei rolls onto his back, Wataru still clinging to his side with one leg over his hip. Out of the corner of his eye he can see Tenshouin’s own mountain of pillows and blankets, but no hint of the piercing blue of his eyes. So either he’s still sleeping, or pretending to do so.
And isn’t that an interesting idea. Tenshouin in bed, listening to him and Wataru, pretending to be asleep while—
Rei sighs, again, just to communicate to Wataru that he’s not happy about the shape of the discussion, irrespective of the outcome. “Let me go to the bathroom first.”
Wataru, to their credit, instantly lets go of Rei, lifting both their arm and leg straight into the air. Not that he’d wanted for them to let him go instantly, but perhaps they too feel a sense of urgency. “Of course Rei, I’ll wait for you.”
Rei takes a moment to pull himself out of bed, glancing over at Tenshouin once or twice as he gets up. He looks asleep, curled up around one of his pillows, though Rei can’t quite make out the shape of his expression without contacts or glasses.
Wataru, now alone in Rei’s bed, takes the opportunity to roll onto their stomach, spreading their limbs like a starfish. Not alluring, but endlessly endearing.
Rei quickly turns around to head into the bathroom. All the better to return as soon as he can.
The dorm room stays quiet, even after Rei closes the door—he spends a moment listening, to see if either Wataru or Eichi breaks out into giggles. Either there’s no farce, Eichi is truly asleep, or Eichi and Wataru both are dedicated to the faithfulness of the fantasy. At this time, all three seem equally likely.
Rei considers if he cares as he washes his hands, staring into the mirror at the shape of his own face without fully taking it in. A vampire doesn’t have a mirror image, yet Sakuma Rei on the other side of this mirror seems to be telling him what he already knows.
He doesn’t mind. There’s a thrum of excitement in the back of his mind, a flush on his cheeks and at the tips of his ears he can’t quite seem to lose, his body intent on reminding him how Wataru’s body had felt against his, how eager they’d been. It’s a thought that not even Tenshouin’s presence could ruin and, to his own surprise, Rei realizes that thinking of Tenshouin, asleep or pretending to, listening to Wataru and him, actually does the opposite of killing his excitement.
He’ll consider just what that means at a later date—there will almost certainly be enough time to think about the implications later. For now, Rei realizes he wants to feel Wataru’s body against his again.
He’s glad about the relative privacy of the deserted bathroom. It must still be very early, considering the complete silence both there and in the hallway. It also means he doesn’t have to worry about running into anyone who may be able to spot his excitement against the dark lines of his pajamas.
When he returns Wataru is still spread out comfortably in bed, though they are no longer imitating a starfish on top of Rei’s sheets.
They’re also no longer wearing the baggy tie-dye shirt and shorts they’d gone to bed with.
Rei crosses the room in large but silent strides. Only a single glance is spared in the direction of Tenshouin, whose presence isn’t forgotten but easily ignored at the sight of Wataru in red and black lace.
Something ugly and possessive flares up inside of him at the sight of it, of Wataru in his colors.
He wants to ask when and how they changed, if this was their idea as well. If they know how irresistible they look.
Instead, he practically throws himself over them, careful to still move quietly, with energy he hadn’t been sure he had until now. Perhaps he’ll regret this later, but luckily the day’s schedule is mostly empty.
He traps Wataru underneath him, his knees on the sides of their hips, his elbows next to their head. Anything they may have said in response to his quick reaction is swallowed in a deep kiss.
It’s not until he stops kissing that he can hear them laugh quietly. “I was supposed to ask you how I look”, Wataru explains, the smile on their face radiant, and the pink blush on their cheeks adorable.
“Like something a creature of the night like myself might want to devour”, Rei responds.
Wataru beams in response and pulls him down into another kiss.
There are rules they all follow, spots where marks are and aren’t allowed. It means both of them are careful not to bite too hard on each other's lips, and Rei avoids Wataru’s neck almost entirely once he moves to kissing down the length of their body.
They’ve changed in recent years. Wataru has always been more muscular than one might assume at first glance, and good at hiding it, but the last year has seen them gain weight (likely a result of the frequent dinners with Tenshouin), hiding bones that Rei had once been able to see and feel under a layer of muscle and fat.
It’s also allowed them to fill the cups of the bra they’re wearing. Rei has decided long ago not to ask about any of Wataru’s decisions, unless they volunteer the information. They will, eventually.
He can appreciate it all the same, grabbing and squeezing at their chest before putting his mouth over one of the thin, lacy cups. They’re not meant to hide, just to entice, and that they have done plenty.
Rei licks until Wataru’s nipple hardens underneath the fabric, takes it into his mouth and continues to tease with tongue and teeth while feeling Wataru writhe underneath him.
Still, Wataru isn’t without their own weapons and Rei soon feels them raise one of their legs until their thigh rests between his own, just present enough to provide minimal pressure against the erection he’s been ignoring.
He grinds against them and lets out an undignified grunt of relief at the pressure, at touch even if it’s nothing more than Wataru’s thigh.
Then he feels their hands on his cheeks, directing his face to look at him. “Lie down. Let me ride you”, they whisper.
Rei nods, relieved to know they’ve got his stamina in mind and rolls off Wataru.
Now Wataru is the one on top of him within moments. For the first time since he’d seen them lying on the bed, Rei can see Wataru’s cock, now straining against the lace underwear which seems to have been designed to only hold one while soft.
When he reaches for it, they bat his hand away with a smile and whisper: “Not yet.”
If that’s something decided by them or Tenshouin, Rei can’t decide at this moment. He obliges their request though, and instead unbuttons the top of his pajamas until, sitting up and with some help from Wataru, he’s pulled off the top.
While sitting up he can also make another grab for Wataru’s chest while they kiss him, squeezing and massaging, pinching at their nipples until their breathing grows more ragged, their back arching into his touch.
Where they pull the lube from he couldn’t say. Maybe one of either of their ears, maybe it’d been hidden in their thick braids, or maybe somehow in the lace of their lingerie. What matters is that it’s suddenly in Rei’s hand, with Wataru giving him a questioning look.
“You’re not prepared?” Rei teases, voice still low as he squeezes some of the clear liquid into his hand and onto his fingers. “I expected a trick up the sleeve of a capable magician.”
“I have plenty up my sleeve, Rei, but you are one of the few I allow up my ass.” Wataru wraps their arms around Rei’s neck as he begins to circle their entrance. He enjoys taking it slow with them, especially since Wataru rarely desires extensive foreplay and is quick to get frustrated.
That makes it all the more satisfying to feel them melt in his arms as he slowly begins to finger them open, breaching with one finger, as always surprised by how easily Wataru controls the tension of their muscles.
He adds lube before inserting another finger, pushing some of it in and spreading the rest around before re-entering with his first, then the next digit. Wataru, their head by now resting against Rei’s shoulder, would have usually started asking for more long ago, but is, in this moment, quiet, perhaps mindful of Tenshouin whose presence Rei has neither been ignoring nor forgetting.
Tenshouin is, in many ways, as much as Rei would want to ignore it, the point of this specific rendezvous.
Not verbally begging for more doesn’t mean Wataru isn’t eager, pushing back against Rei and circling their own hips to demonstrate that they’re perfectly capable of taking him. It’s endearing, to feel them wordlessly desperate, but Rei can feel his own eagerness growing as well, and can only stretch his own patience so much.
When he asks Wataru “Are you ready”, it’s just as much about telling them that he definitely is.
Their response, a breathily laughed “Yes”, is testament to that as well.
When Rei begins to reach for his pants, Wataru shakes their head. “Lie down. Let me take care of you, Rei.”
Rei sinks back, unable to say no, not with Wataru looking at him, face flushed, their needy gasps still ringing in his ears. He knows this, him on his back and Wataru sitting above him, must be yet another part of their plan, but by now he’s become a willing cog in their machinations.
Wataru, clearly desperate enough at this point to not want to engage in too many antics, still makes all the appreciative sounds Rei would expect as they pull down his pants, revealing his cock which, by now, stands up almost perfectly straight.
Now kneeling between Rei’s legs, Wataru looks up at him. They briefly put a finger to their lips, which is the only warning Rei gets before they lean down to give the head of Rei’s cock a kiss, before swallowing it deeper.
It’s a good thing they warned him, giving Rei just enough time to brace himself and to put a hand over his mouth to swallow any involuntary sounds. Whichever noise was about to escape him when they swirl their tongue around his head is lost against the pressure of his own palm.
Wataru doesn’t swallow him as far as Rei knows they can, but when he tries to move his hips— not entirely intentionally— for more, he realizes that they’re holding him down, their hands on his hips.
“Wataru,” Rei groans, not expecting a response.
They let out an amused hum, and when Rei turns to look at them he realizes they’ve been looking at him, amusement sparkling in their eyes.
Rei attempts to buck his hips again, and this time Wataru actually pulls off his dick. “Aren’t you impatient~”
“You’re one to talk, weren’t you just begging me to—”
“Shhh.” Wataru grins and crawls over the bed until they’re looming over Rei. Their two long braids fall over their shoulders and onto Rei’s chest. One of them, he realizes up close, isn’t done quite as skillfully as the other one. Yet another reminder of Tenshouin’s presence.
When they put one finger over Rei’s mouth to shush him properly, he takes it between his lips.
It achieves its intended goal— Wataru starts laughing. Not their usual loud laugh but a much more quiet, private one. One reserved almost exclusively for moments like this one, for the quiet time just between the two of them.
Rei can’t say he understands Wataru’s desire to play at infidelity like this, but if it allows him to see another side of them he hadn’t even thought possible before; quiet and devious, then he will be the last one to complain.
He pulls at one of the lacy cups of their bra, hooks his finger under it when he realizes the lace is not elastic enough to be pulled entirely to the side.
“You like it?” Wataru murmurs, leaning forward so they can almost whisper into Rei’s ear. They sound very smug about it, so they must have known.
“I wouldn’t usually go for lace but it suits you.” There’s a subtle bat-motif worked into the lace, and the entire ensemble is clearly very expensive and fits Wataru well, both in color and shape. He wishes they’d wear darker colors more often.
“Oh? Does Undead’s Sakuma Rei prefer the appearance of leather to lace?”
And isn’t that a thought. There is certainly enough leather in Rei’s closet to dress Wataru in it from head to toe right now, even if their measurements are likely slightly different. It might be very tight on them. Of course, that is not a deterrent in the least.
Rei uses his other hand to cup Wataru through the other cup, running one thumb over their chest in small circles, repeatedly stroking their nipple. “This is good,” he informs them, and means it. “I wouldn’t kick you out of the bed in a leather harness either.”
“I will remember that for next time.” Wataru nods with a grin and leans back again, clearly having remembered what they’re here for. Rei’s arms, still outstretched from where he’d been touching their chest, get relocated to their hips as Wataru reaches behind themself.
Rei can feel their fingers wrap around his dick and it takes some restraint not to thrust up into the touch, especially when they slowly line him up, pushing the thin underwear to the side so Rei can push inside them unimpeded.
He holds still for them, knowing that’s likely what they expect, but his grip on their hips does tighten as they go lower and lower.
It’s satisfying to notice neither of them is capable of staying entirely quiet, with Wataru’s breath growing shaky and Rei’s own getting deeper. Neither of them moans, but it’s close.
Once they’re low enough to almost sit on Rei’s lap once more, Wataru rolls their hips to grind down.
“Fuck, Wataru.”
Wataru giggles, breathily. “You are, yes. Amazing, isn’t it?”
When they begin to move, it’s the same rolling motion, and Rei finds himself chasing after the movement of their hips with his own for once, holding onto their hips tighter to attempt to keep them in place. Though of course keeping Wataru restrained in place has never worked before, and it doesn’t work this time either.
“Relax, Rei.” Wataru puts one hand on his chest and leans forward.
Rei almost laughs. “How could I relax with you right here?” To accentuate his point, he adjusts his hands slightly to grab their ass instead of holding them by the hips, squeezing as they continue to ride him.
Maybe in response, maybe for some other reason, he can feel Wataru tighten, which in turn elicits a gasped groan from Rei, one he, this time, cannot quite control the volume of. Not that he cares, at this point—Tenshouin has never fully left his mind, but by now the vision Wataru is presenting is occupying almost all of it.
They’ve grown flushed, in a way Rei knows he must be too, though he knows for them it’s purely the arousal and little to do with physical exertion. Their mouth has fallen open slightly, their eyes half-lidded but facing him with an intensity he can’t deny.
When he thrusts up to chase after them another time, Wataru doesn’t chastise him again. Instead they let out a surprised sound, and Rei can feel the pressure of them squeezing more tightly around him. That is enough to stop the part of his brain smug about being capable of surprising Hibiki Wataru.
“Fuck, Wataru.”
“You’re repeating yourself~,” Wataru responds, sounding amused, clearly knowing full well just what they’re doing to him.
Rei squeezes their ass harder, digging his nails just slightly into their skin, and he gets the satisfaction of Wataru’s breath catching again.
They begin to ride him more intensely, small sounds escaping them as their eyes flutter shut. Wataru is always a vision, but especially now, as they are looming slightly over Rei, their strength and flexibility on full display for nobody but him to enjoy.
It is exceptionally hard to tear his eyes away from the expression on their face, to not admire the sway of their braids as they move, or the sight he is now getting of the way their heaving breath expands their chest, still constrained in its bra, still visibly wet from where Rei had sucked on it. His eyes wander lower, to where their cock has managed to escape their panties, moving with the thrusts of their hips.
Their previous denial is lost in the rush and heat of the moment as he reaches for their dick another time, though it does not matter now—Wataru, too, seems to be too preoccupied to notice as he wraps one hand around them.
Wataru gasps at the touch, even their concern about the noise seemingly forgotten, and Rei joins them when they once again tighten around his cock as he swipes across their head, pulling their foreskin back to reach for much more sensitive spots, spreading pre both over his hand and their dick as he does.
“Rei~” Wataru’s voice is little more than a whine, which is Rei’s first real indicator of just how close they must be, to hear them entirely unguarded like this.
Not that he would fare much better if he were to try and talk, which is why instead Rei lets out a moaned grunt in agreement, thrusting up into Wataru once again.
They’re a sight to behold as they gasp in pleasure, their own hand reaching for Rei’s wrist to hold onto it, though they don’t stop him from continuing to touch them.
“Rei I won’t last much longer if you—”
Rei almost laughs in response. “Don’t worry,” is all he manages to breathe out without getting too loud once more, though by now the idea of Tenshouin still being asleep is almost laughable.
He doesn’t want to turn his head, doesn’t want to look away from Wataru for even one second, afraid of breaking the spell, but he hopes he’s looking, hopes that Tenshouin can see Wataru, sweaty and flushed from pleasure. He hopes that it makes him seethe, that it makes that cold, black heart of his burst with jealousy and desire.
Tenshouin might be more possessive of Wataru than Rei could ever imagine being of anyone, but right now it is Rei who is making them moan with pleasure, it’s Rei’s colors they’ve dressed themself in, his spit on their skin, his hand on their dick, his cock buried deep inside them.
He doesn’t look, but even with his legs tensing and the pleasure growing, he notices the way Wataru’s gaze flicks to the side, to the other side of the divider, though they too do not show any desire to stop. Instead they increase the energy, putting more and more into the movement of their hips, bearing down onto Rei and then thrusting their cock forward into his hand.
It shouldn’t be the image of blue eyes that brings Rei over the edge eventually, but he’s uncertain if he could truly deny that it wasn’t. Climax crashes over him like a wave, and Rei finds himself thrusting up with energy he hadn’t been sure he possessed.
Soon after, he’s collapsed almost entirely, his softening dick having already slipped out of Wataru, his hand slipped off theirs, and Wataru looking both pleased and very desperate above him.
An undeniably irresistible sight, even as limp and satisfied Rei is feeling right now. He reaches for their thighs, pulling until Wataru seems to get the message.
They knee-crawl up his body, until they’re in front of him, their dick standing up in front of Rei’s face. “Is this where the vampire wishes to drink of me?”, they say, sounding amused.
“You know I have no taste for blood, I’d rather suck you dry like this,” Rei responds, already having his hand wrapped around the base of Wataru’s dick. he knows they won’t last long, not with how close they must be.
Sitting over him like this, Wataru must still have a good sight of what exactly is happening on the bed next to him, even if they are leaning forward to better thrust into Rei’s mouth. He focuses on relaxing his throat and jaw, only involving his tongue for the brief moments in which Wataru stills, enjoying the gasps that he’s able to tease out of them.
It doesn’t take long until he can taste salty liquid, feel it on the back of his tongue and slowly pool further as Wataru pulls out through their climax, the last drops of it hitting Rei’s lips.
He licks them up without giving it much thought, though the very satisfied grin on Wataru’s face as he does tells him it’s what they’d hoped for. Rei gives their now softening cock one last kiss, for Wataru hides it behind the lace of the panties once more, leaving its presence marked by a very wet spot.
Soon, they’re in each other's arms again, and Rei can almost feel himself drifting off to sleep once more.
