"You want me to what?"
Grian's face went even redder at Mumbo's question, squirming under his gaze. "I mean- If you don't want to we don't have to, I just thought it'd be interesting to think about," he squeaked quietly, now avoiding eye contact.
"I'm not saying no," Mumbo quickly assured him, resting a hand on his shoulder. "I just-" He squeezed his eyes shut for a moment, feeling his own face start to flush before he opened them again. "Clarify?" His voice cracked.
Grian bit his lower lip, his wings fluffing up a bit. "I just thought it might be… interesting if maybe you would fuck me when I was asleep," he repeated his statement from before, not clarifying at all. "I could maybe take a bit of melatonin, I'd sleep a bit deeper and you could maybe… use me." He sounded so unsure, Mumbo had to change that.
He moved to tilt Grian's head up a bit, suddenly surging forward to kiss him. He might have been panting softly when he pulled away again. "I might definitely be interested in that," he admitted with a breathless laugh.
Grian echoed that laugh, a big grin spreading across his face right where it belonged. "And to think I was so nervous about this," he snickered softly, "you're just as messed up about this as I am."
"H-hey!" He laughed a little, feeling his face go even redder. "You're the one who brought it up in the first place!"
"And you're the one that's red as a sweetberry about it," Grian teased him even more, before his gaze darkened. "Come on, tell me you haven't thought about it before. My limp, sleeping body, all yours for the taking. Could move and manipulate me however you want, and fill me up so I wake up dripping the morning after, just left to imagine what happened to me." Grian's voice had grown husky as he pressed closer to Mumbo, nipping at his throat. Damn did this man know how to get him worked up.
"You're a menace," Mumbo groaned, wrapping his arms around Grian's waist to pull him impossibly closer. "The absolute worst."
"And that's why your boner is pressing into my side like that, huh?"
"Shut up," Mumbo huffed, leaning down to kiss Grian again, already carefully backing the other towards the bedroom.
Tonight was the night.
It had been a couple days since he and Grian had talked about the concept, and fuck was Mumbo eager to please.
The avian had popped some pills an hour or two ago, resting his head in Mumbo's lap as he ran his fingers through his sandy hair, murmuring softly and watching him easily doze off. His face was so relaxed, Mumbo had always enjoyed watching him sleep— in the least creepy, most boyfriendy way possible— but this was different, anticipation warming his gut.
He waited a little longer, just to make sure Grian was well and truly asleep, nudging him slightly just to make sure he wasn’t about to wake up again. Mumbo took a deep breath, watching as Grian didn’t react, at all.
Mumbo carefully shifted, laying Grian’s head back against the pillows as he slid out from under him, propping his hips up onto another. The two of them were both only wearing boxers, they’d agreed on that just to make it easier, but the slight chill in the air was making Mumbo regret it now.
“Easy access,” Grian supplied, kicking off his jeans and leaving them on the floor next to his shirt before crawling into the bed. “Then you still get to undress me, but you don’t have to deal with my pajamas.”
“I like dealing with your pajamas,” Mumbo piped up, dealing with the buttons on his shirt before messily folding it up and setting it aside.
“Slicing them up to unusable shreds is not dealing with them, Mumbo Jumbo,” Grian scolded, though the mirth in his voice was unmistakable.
“You thought it was hot!”
“I think you’re hot.”
He felt a bit bad ignoring the goosebumps appearing along Grian's skin as he hooked his fingers into the other's waistband, slowly pulling it down— but he was quickly distracted as the sight underneath him stole away his breath.
Grian's legs were parted slightly so Mumbo could sit comfortably between them, and he was trying so hard not to drool as the boxers stuck slightly, a visible wet spot on them where Grian's slick had leaked through to. He knew he'd been teasing the avian a bit while waiting for the medication to kick in, but he hadn't expected it to affect him so much, so visibly.
Not only that, but pushing the other's legs a little further apart once he'd sat between them again actually did have Mumbo drooling now, Grian's dick was poking out from between his folds, slick and shiny and so hard already. He must have really liked the teasing then.
He couldn't help himself, leaning down and licking a long, flat-tongued stripe along Grian's folds, moaning softly at the taste as he paused to give his dick a slightly sharper suck. Grian's breath hitched at the action, hips twitching ever so slightly, but aside from that the sleeping avian gave no indication at all that he'd even noticed. Mumbo was burning up inside.
He moaned softly again, blindly reaching for the lube he knew that he'd set aside earlier while he continued to gently lick and suck at Grian's dick, ducking his head a little more to taste more of his dripping wetness, groaning to himself as he pressed his tongue into the other for just a moment.
Grian's hips were still twitching the slightest bit, but he otherwise didn't react when Mumbo's first lubed finger slipped inside of him— Grian had offered to prep before they had even made it to the bed, and Mumbo all but begged him not to, to let him do it while he was asleep. It was worth it, though Mumbo was faintly worried about the mischievous look on Grian's face, but that was a 'problem' for another time.
Even with Mumbo gently— but oh-so-eagerly— eating him out, sucking his dick and pressing his tongue in alongside his fingers, Grian only finally let out a proper sound when Mumbo pressed in his third finger, and at the whimpering moan Mumbo immediately raised his head to check on him. He was panting, he could feel his chin all but dripping in slick, but Grian hadn't woken, his brows only just beginning to knit together a little though his cheeks were so, so red.
"You've literally slit my throat while fucking before, and now you're worried about sticking your dick in me while I'm asleep?" Grian sounded more amused than anything else, which Mumbo was grateful for.
He could feel his cheeks going red in embarrassment, worried that maybe he was being a little too concerned about the whole situation. "We've just… never been in a situation where you couldn't safeword before," Mumbo explained, eyes darting to the side. If Grian wasn't worried about it, then it probably wasn't as big of a deal as he thought.
"Oh, Mumbo." And Grian was right in front of him, pressing a gentle kiss to his lips, surprising him. "You're too sweet, what did I do to deserve you?"
He blinked, somewhat startled by the other's change in tone. "What do you mean?"
"Don't worry about it," Grian smiled softly, and then there was another kiss, longer, but just as gentle, sweet. "How about this, nothing too intense, alright?" He offered when they parted again. "Nice and normal vanilla sex, aside from the part where I'm asleep," he snickered at that part, "and if I wake up, it's a yellow, okay?"
That almost instantly soothed Mumbo's anxieties, Grian was too good to him, so patient and understanding. "We stop and talk then?"
"We'll stop and talk, if it happens."
“Fuck,” Mumbo breathed out, watching Grian’s face twitch as he slowly thrust his fingers in and out. His eyes stayed closed, his breathing otherwise even aside from the occasional hitch when Mumbo thrust his fingers in. He wanted to tease Grian like this forever, spreading him out, stretching him, until the other was squirming, begging, lost for all words. He could only imagine how beautiful he’d look like that. That was for another time though, when he was awake and Mumbo’s dick didn’t feel like it was about to explode.
Slowly he slid his fingers out, hearing the other whine softly at the emptiness, though Grian’s eyes were still firmly shut. God he was gorgeous, lips parted ever so slightly to let out his slow breaths, chest rising and falling with each one, hair splayed out around his head like a halo; not to mention the flush running from his cheeks all the way down his chest, almost as bright as his reddest feathers.
Mumbo couldn't help himself, suddenly surging forward to kiss at Grian's slack lips, unable to stop another groan from escaping him as he nipped gently, pulling away to see them turn even redder. So beautiful. He let out a soft shuddering breath of his own, watching as Grian's brows twitched slightly at the puff of air, before pulling back just enough to kick off his own boxers, tossing them to the side for later. He was absolutely throbbing.
Mumbo hissed softly as his hand wrapped around his length, spreading the lube as quickly as he could before hoisting Grian's legs up and over his shoulders. At the continued lack of reaction from the other, he lined up against his entrance— hot, throbbing, wet— and then slowly pressed in.
The moan that escaped Mumbo was guttural, he wanted nothing more than to close his eyes, let his head fall forward, and just sink into the heat of the other. Instead he forced himself to keep his eyes open, focused on Grian's face; he didn't dare miss the way it twisted up in pleasure, breaths coming out in faster, harder pants as Mumbo slowly sunk into him, groaning under his breath.
He was sure Grian would have bruises from how tightly he was holding onto his thighs, trying to control himself, it was so hard not to give in, to take his pleasure for himself. Mumbo swore softly when he finally bottomed out, feeling Grian unconsciously squeeze around him, breath stuttering as he tried to keep his hips from bucking into the warm, welcoming heat.
He took a couple deep breaths to ground himself before slowly pulling back until just the tip was left inside, then slowly— but firmly— he thrust back in.
Grian moaned outright at that, it was muffled, filled with sleep, but unmistakable as his own hips twitched at the movement. Mumbo couldn't hold back anymore, the soft sound almost muffled by the blood suddenly rushing in his ears. His grip on Grian's soft thighs only got tighter as he started up a rhythm, slow but firm. Each thrust pulled a soft sound out of Grian, and Mumbo couldn't help but echo them, he leaned forwards again to nip at Grian's throat, pressing gentle kisses just to feel the vibrations of his quiet, sleeping voice.
He was going to go crazy. Grian was going to drive him crazy. Mumbo pressed harder on Grian's thighs, closer to his chest, all but folding the other up, making him so small. He could take it, Mumbo knew, he'd seen Grian in even more strenuous positions before.
“I want to mark you up.” Mumbo’s voice was quiet, unsure. This was his own request, his first for the night. He wasn’t even sure if he was allowed to make requests honestly, this was technically for Grian, even if he was going to be asleep.
“Mark me up?” Grian repeated. It wasn’t fair how he was so calm about everything, he didn’t even look up from the plans he was sketching out. “What do you mean?”
“Well when you’re- when you’re sleeping and I-”
“-I know when, Mumbo.” That teasing tone was in his voice again. “I meant how?”
“Like- like hickeys, or biting you. I know we already agreed it’d be…” He waved his hand, searching for the word. “Normal. Vanilla, but I still want to-”
“You’re always allowed to bite me,” Grian cut him off again, which honestly Mumbo was grateful for, if allowed he would just ramble for ages.
“Always?” Mumbo repeated, trying to come up behind him as silently as possible.
“Mhm, whenever you want.” Grian’s wings ruffled a little, so much for silent, it seemed the other heard him, even if he wasn’t turning around to look.
“Even now?”
“Especially now.”
Mumbo bit down suddenly at Grian's throat, unable to stop himself from leaving a nice, dark hickey, moaning into the otherwise pale skin as his thrusts sped up a bit.
"M-Mumb…" Grian murmured ever so faintly, some mix between a whine and a moan.
With an even louder moan, Mumbo managed to tear himself away from the other's throat, eyes flickering up to look at his face again.
Asleep. He was still asleep. And he'd moaned out Mumbo's name, was he dreaming? He couldn't keep the thought from rattling around in his brain, a whine of his own escaping.
He could feel himself getting closer, panting harder, hotter and hotter with every passing moment. Mumbo kept his steady pace though, thrusting harder, deeper; fuck he could feel Grian twitching around him, making his thoughts go hazy. Was he close? He had to be, right?
Mumbo knew this was for his own pleasure— that was the point, for him to take and use and do whatever he wanted, Grian didn't have to come— but Mumbo needed to feel that familiar almost-painful tightness. At this point it had become almost a requirement to his own orgasm. "Fuck, Grian," Mumbo felt himself growl into the other's ear, earning himself another quiet whine, a stuttering breath from the relaxed body beneath him. He was so close he just needed…
Mumbo let go of one of Grian's legs, sliding down to his dick only to gasp at the sudden tightness he was rocking into, vision going a bit fuzzy as he finally sped up.
"Oh fuck, Grian," he whined softly, glad the other wasn't properly awake to hear the pathetic sound. He was so, so close, just a little more.
Just a little more attention to Grian's dick, squeezing and stroking and- Mumbo couldn't stop the loud moan that escaped him as Grian suddenly came. His body went stiff, twitching slightly as a whine— louder than anything else that had come out of his mouth tonight— escaped him. Grian was pulsing around him, and if he didn't know any better Mumbo would have said he was purposefully trying to milk him, to get him to come even in his sleep. Perfect, perfect, he was so perfect for him.
It only took another three thrusts before Mumbo buried himself to the hilt again, muffling his own loud moan into Grian's shoulder as his hips twitched, filling the avian just like he always asked for. Or begged, when Mumbo made him.
"You'll come in me, right?"
Mumbo sputtered, choking on the coffee he'd been trying to drink. "W-what?"
Grian was snickering quietly at the little show, and Mumbo would be embarrassed if he wasn't so startled. "When I'm asleep, you'll come in me? I wanna wake up with it still inside of me."
Mumbo's cheeks were burning bright red now at just how casually Grian was bringing this up. "Won't that be uncomfortable? I can just clean it up after-"
"Please, Mumbo? I want it."
He almost missed the quiet chirp that left the other at the feeling of being filled, brain hazy, floating as he tried to catch his breath.
It took a couple of minutes for Mumbo to convince himself not to just fall asleep like that, inhaling a little sharply as he finally pulled out, softening length sensitive. He didn't miss the way Grian's hips twitched, or the soft moan that barely escaped his lips. He rubbed gently at the avian's thighs, pressing gentle kisses to the skin there as he slowly lowered his legs again, sure he wanted him sore , but not out of commission, no matter how hot that would be.
Mumbo was searching for Grian's boxers on shaky legs when he heard the quietest whimper, almost thinking he imagined it. When he looked up his breath caught. Just below Grian's twitching dick, he could see his own come slowly beginning to drip out of the other.
He swore softly, definitely not feeling possessive as he reached over, slipping two fingers into the other to carefully press it back in, not wanting to waste a drop. Grian wouldn't mind, he was sure, if only he were awake to be all embarrassed at the action though— Another time. Mumbo quickly shook the scenario from his head for now, even as his length made an impressive effort so soon again.
After another moment, Mumbo gave up on the search for Grian's boxers, instead grabbing his own and sliding them up the avian's legs, over his waist, hips, keeping everything inside of him— or at least as decently as a pair of boxers could— and making that possessive little beast in Mumbo's chest purr.
Mumbo let out a soft, pleased hum at the sight before climbing up onto the bed next to him, not caring about his own nakedness. It didn't matter, not so long as he could pull the blanket over the two of them and hold Grian close, the avian cuddling up to him even in his sleep.
He hummed again, pressing a gentle kiss to the tip of Grian's nose, then each cheek, and finally his lips again. "Love you," he murmured, already feeling himself drifting off to sleep as well.
Grian mumbled softly in return, and even though he wasn't awake, Mumbo could tell what it was supposed to be.
Beyond pleased, Mumbo felt his own eyelids beginning to get heavy, eventually falling asleep with the other curled up at his side, just where he belonged.
Sunlight shining in through the window, directly onto Mumbo’s face, was what woke him in the morning. Groaning quietly, displeased, he turned his head to the side, hiding his face in the top of Grian’s head, nuzzling a little into his hair. Comfortable now, but unable to fall asleep again, he sighed softly, letting his mind wander back to the memories of last night.
He was pulled out of his thoughts only a couple minutes later, feeling Grian shift in his arms. Mumbo pulled back just a bit to get a better look at him, catching sight of the avian just in time for him to yawn, fuck he was adorable.
“Morning, birdie,” Mumbo cooed, watching as Grian tried to blink the sleep from his eyes. “How are you feeling?”
“Mm, tired,” Grian mumbled with a little laugh. He moved to sit up a little, groaning softly. “And sore, mm.” He smiled a little, cheeks slightly red as he met Mumbo’s eyes, licking his lips. “You really did use me, huh?”
Mumbo felt his own cheeks going red, the look in Grian’s eyes waking him up a little faster than he was planning. “You told me to, plus you were so hot,” he sighed, propping himself up on his elbows. “You said my name.”
“I was having a pretty good dream,” Grian grinned, pushing the covers down before blinking in confusion. “These aren’t my boxers.”
Mumbo couldn’t stop the laugh that escaped him at that, covering his mouth as he tried not to cackle.
“Mumbo! Did you put your boxers on me?” Grian asked, voice accusatory as he tried not to laugh too, turning over to straddle the other. “You’re still naked!” An actual laugh now.
“I was tired!” And there was the cackle, the entire ordeal was a little embarrassing. “I didn’t want to find yours, and- um-” Mumbo felt his face go even hotter. “Didn’t really think you’d want my come leaking all over the bed.”
“So it’s just leaking into your boxers now,” Grian grinned, grinding down suddenly, unexpectedly. “Sounds reasonable.”
He gasped softly at the action, hands moving to grab at Grian’s hips. “Listen, unless you wanted me to plug you up instead-” He did not miss the way Grian’s eyes widened at the thought.
“Could you?” He asked suddenly, leaning forwards, hands pressing down into the bed on each side of Mumbo. “Fuck that’d be so hot.”
“I thought you were about to ride me,” Mumbo whined, pouting as one of his hands slid around to the small of Grian’s back, rubbing at the bare skin there.
“I meant another time,” Grian rolled his eyes, huffing a little laugh. “Of course I’m going to ride you. Like I said, you gave me a really good dream.”
“O-oh.” Mumbo laughed slightly nervously. He had a bit of a feeling he was not getting out of bed for the rest of the morning. Not that he minded at all, especially with the way Grian kissed him good morning.
