Grumbo comm

First of the comms is done, and it's grumbo for @frootyloopy as part of his AU that you can find here! It was very fun to write (once I figured out how I wanted to start it lmao) even if I've never written grumbo before sdfghj

Comms are closed now at the moment, got one more to finish and then I mayyyy end up reopening them in a month or two, depending on how work goes. We'll see.

Anyway, pls enjoy :3

Mumbo had hoped to see Grian, when he made his way to the nun’s quarters, but the man was nowhere to be found. He sighs, disappointed, and turns to go. He must be somewhere around here, Mumbo is sure he can find him.

As he turns to leave, though, something catches his eye. He looks, and there, placed unceremoniously, lays a pair of underwear on top of the laundry basket. He stares at it for a bit and feels his face slowly get more red. 

He thinks back to Grian. The man’s been a massive tease lately, letting him touch but not nearly as much as he really wants to, and he’d been hoping to find him here to maybe…release some tension. And he’s not here, but maybe…maybe he could…

If he’s quick, it’s not like Grian will know what he’s done. Mumbo can take care of himself, and deal with Grian’s teasing for a little longer. 

He makes sure the door is closed, plucks the pair of underwear from where it sits, and then walks closer to Grian’s bed. He runs his hands along the sheets for just a moment before getting onto it. He can’t take too long. 

He pulls his pants down just enough to let his cock spring free, already half hard at the thought of what he’s about to do. With one hand tracing along the edge of the underwear, the other wraps around himself and he gives a slow stroke. A groan falls from his lips unbidden. 

His gaze wanders down to the pair of underwear held in his hand. Slowly, hesitantly, he brings it up to his face and gives a cautious sniff. Immediately, he groans. He never imagined it could smell so good. He gives a deeper inhale and works his fist over his cock faster. Already, he can feel himself getting close. 

He thrusts into his hand a little, hoping to come quickly so he can clean up and leave, but the creak of the door has his thoughts snapping to a halt as he looks up and sees Grian in the doorway, watching him.

He freezes immediately, eyes wide, as Grian blinks before his lips curl into a grin.

Oh, no. He’s absolutely doomed.

“Aww,” Grian coos, watching the way Mumbo’s face flushes a deep red. “You just wanted me that badly, did you?” He closes the door behind him and steps closer, and Mumbo swallows as he crawls onto the bed. 

He looks up at him, crowding him against the bed, and all he can think about is how beautiful Grian is. Grian smiles at him, and he’s powerless to do anything but smile back.

“Will you let me lend a hand?” Grian asks him, and Mumbo remembers that he is very much sitting on Grian’s bed with his cock still out. He nods rapidly and Grian grins.

He starts slow. Hand over his dick, never truly pressing against him, just providing the promise of touch. The whisper of pressure. He was really close, but he supposes Grian doesn’t want him to come yet. They’ve only just started.

He slowly starts to actually stroke him, watching the way precum beads at the tip. Grian makes eye contact with Mumbo as he leans down and swipes it up with his tongue in a truly lewd gesture, and Mumbo whines. 

He starts to move down and takes the tip into his mouth, shallowly sucking. He moves a little further down, and Mumbo can’t help it as his hips buck a little, desperate for more of that tight, hot heat around his cock. But Grian simply holds his hips down, and Mumbo is left unable to do anything but take the pace that Grian gives him. He whimpers.

Grian looks almost sinful like this, his mouth stretched obscenely around Mumbo’s cock, taking as much of it as he can. What he’s not able to fit, his hands wrap around. Every part of his cock is lavished with attention, and Mumbo is quite sure he’s going to come very soon.

Somehow, Grian seems to know this, and he pulls back. He swirls his tongue around the tip, collecting another bit of precum, before looking up at Mumbo with a smirk.

“So good,” he says, voice almost…salacious. Mumbo swallows. Grian pulls further back, then works on getting his clothes off. He tosses his underwear to Mumbo, grinning. “Since you like it so much,” he teases with a wink.

Flustered, Mumbo can’t even come up with anything to say to that. He catches the pair of underwear, hesitant, but…well, Grian did throw it to him, and he already knows, so…

Slowly, he brings it closer to his face to give it a curious sniff. He moans almost immediately. The scent is so much stronger, and he can feel a bit of Grian’s slick on it. He pulls it closer and practically inhales the scent, only half aware of the way Grian chuckles at him.

He almost doesn’t notice Grian crawling back onto the bed, straddling him, and then reaching over to stretch himself out. Mumbo can’t help the way he perks up - he’d been hoping they’d go this far, but he hadn’t wanted to get his hopes up. But with the way Grian looks at him as he spreads his fingers buried into his cunt, it takes everything within him to not immediately press into his hole.

Briefly, he has a moment of guilt, but he tries to push it away. Grian is - he’s an angel, sent to reward him. Who would he be to turn that gift away? He has to show that he’s truly appreciative of the gift God has sent him.

Grian grabbing the base of his dick pulls him out of his thoughts. Seems he’s done stretching himself, then. Luckily, Grian doesn’t make him wait much longer. He bumps his dick against his clit first, and Mumbo swallows as he registers the sheer difference in size between the two. He knows he’s a large man, but he doesn’t think he’ll ever get over the way he’s so much bigger than Grian in every way.

And then Grian’s properly lining them up and lowering himself so Mumbo presses in. Mumbo throws his head back and worries for a moment that he’s going to faint from how tight Grian is. They’ve not done this many times, only a few times now, and the squeeze of Grian around him still catches him off guard.

Bit by bit, Grian takes more and more of him. His hands go to Grian’s thighs, digging in slightly as he bottoms out. He sees the bulge in Grian’s stomach and groans, hips thrusting into him, desperate for friction. 

Grian gasps, squeezing around him even more, and then he starts moving. Lifting himself up on shaky legs and dropping back down. He repeats that, grinding against him for a moment each time he bottoms out. 

Mumbo alternates between looking at his face, and the feathers on his chest, and the bulge in his stomach, and the way his cunt stretches around his cock. He swears he’s never seen anyone more beautiful. How could this be wrong, when Grian looks like he was made to take him? He - he wants -

“Grian,” he says, looking pleadingly up at him. “I wanna - can I - can I kiss you? Please?”

Grian smiles at him, all teeth behind bitten lips. He reaches forward to cup Mumbo’s face and pulls him into a kiss. Mumbo moans into his mouth, desperately kissing him back. Grian goes back to rocking against him, and Mumbo whimpers. 

“Grian,” he says softly, pulling back and whispering against his lips. “I’m gonna -”

“Go on, Mumby,” Grian encourages him, “doing so well, come in me, fill me up, please -”

Grian grinds against him one last time, and that’s it for Mumbo, he’s gone. He moans as he comes, quickly filling Grian’s cunt with spurt after spurt of cum. Grian comes soon after, his cunt spasming around Mumbo’s cock and drawing more cum out of him.

He collapses against the bed as soon as he’s done, Grian’s underwear off to the side, forgotten. Grian lays down on top of him, still with Mumbo’s cock buried in him. Mumbo chances a glance down and can’t help the way his cock twitches as he realizes the bulge is now slightly bigger, Grian filled with both his dick and his cum. 

He doesn’t have the energy to go a second round, however, so instead he simply wraps his arms around Grian and holds him close as he tries to catch his breath. Grian shifts slightly, and Mumbo makes a sound of protest, which Grian chuckles at.

“I’m not going far, Mumbo,” he soothes. True to his word, he simply shifts them so they’re laying on their side and Grian can curl into his side, head pressed on his chest. He lifts his head so he can kiss Mumbo again, and he relaxes, content to lazily kiss him as they come down from their highs. 

He knows others wouldn’t approve of his relationship with Grian, but that doesn’t matter, he tells himself. He can hold this beautiful angel and kiss him, and that’s all he needs.
