Chapter Text
The base is empty, just like Pain had promised him.
Obito hurries to one of the bedrooms closest to the kitchen, laying down a still-pliant Deidara on the bed.
Before Deidara can rouse, Obito tears himself away from the burning omega and hurries into the kitchen. The cupboards and the fridge are stocked with food and water, as he had instructed Zetsu to do. He grabs an armful of water bottles and heads back to the bedroom.
The moment Obito steps into the room, Deidara lets out a soft moan and his head turns to his direction, though his gaze remains distant and hazy.
Perhaps relaxing the omega only hastened his heat.
Had Deidara been actively trying to fight back his heat?
Obito places the water bottles by the foot of the bed and hurries to Deidara’s side, kneeling down and trying his best to ignore the thick scent.
“Are you feeling alright, senpai?” Tobi asks.
Deidara only moans in reply. He turns his head more, eyes watery and dark, boring deep into Obito’s soul. Obito waits patiently for Deidara to answer him, swallowing thickly when Deidara shifts and a waft of his heat-thickened scent comes washing over him.
He doesn’t realize what he’s doing until he looks down.
Obito should not be surprised, but he finds himself stock-still as he notices Deidara’s dick straining against his pants. Deidara lets out a quiet whine, a silent request, and Obito just nods once because he knows.
Deidara moans, glad that he has permission, and shoves his hand roughly into his pants. Obito cannot see very well with the pants in the way, but he knows Deidara is jerking himself off, given the frantic movements of his hand and the needy whines that are spilling from his lips.
Obito watches, transfixed, as Deidara’s hand seems to quicken. He only looks away when Deidara lets out another whine, his other arm coming to wrap around Obito’s neck and pulling him close.
“T-Tobi, hm,” Deidara moans, mouthing along the edge of his mask.
“Deidara,” Obito replies, voice gone hoarse and a little husky. He grunts when he is pulled in tighter, his own erection bumping against the side of the bed.
“Please,” Deidara moans and then he trails off into a whine.
Obito, curious, turns his head and notices that Deidara is no longer stroking himself. Instead, he has reached further and—
Well, he’s fingering himself.
Obito’s mouth goes dry. He feels himself twitch in his pants and Obito cannot help but thrust his hips forward once, wanting any kind of friction on himself. The head of his penis bumps up against the side of the bed again, and although it brings him minimum pleasure, he continues to rub himself against the wood.
He reaches up, frenzied, and takes off his mask. Deidara gasps, though he does not have the ability or the time to take in Obito’s face. Within seconds of taking off his mask and chucking it somewhere across the room, Obito leans forward and presses a bruising kiss on Deidara’s lips.
The omega responds eagerly, parting his mouth and letting Obito lick into him. Obito presses a hand on Deidara’s chest, just palming against the heated skin, and then Deidara comes with a choked off moan, his body tensing and arching.
Deidara breaks away from the kiss. He leans back on the bed and looks up at the ceiling, trying to catch his breath. Obito can hear the slick sound of Deidara pulling his fingers out of himself.
He closes his eyes and takes a deep breath. Deidara’s heat is coming in full force now, but his orgasm has brought them a few seconds of clarity.
“Tobi…”
Deidara’s feeble voice jerks him back to reality and Obito opens his eyes, finding himself staring right into Deidara’s eyes.
“Please…” Deidara mutters and he trails off, gazing into the distance. Obito waits for him to continue, but Deidara does not speak.
“What do you want?” Obito asks.
Deidara’s eyes snap back to him, and his eyebrows furrow. “You…” Deidara says.
Obito leans back a little, pulling his hand back to scratch at his chin. “Yes,” he says, clearing his throat.
Deidara’s gaze trails down, eyes lingering at the broadness of Obito’s chest, and says nothing. Soon, the omega begins to fidget once more and his scent grows sweeter.
“Quick,” says Obito, hurrying to lift the upper part of Deidara’s body up so that he faces him, “tell me what you want, I won’t do it without your permission.”
Deidara groans and tries to shake Obito away, pointedly not looking at Obito’s face. “Just do it,” he mutters. “Your kind doesn’t care about consent, yeah.”
“No,” Obito says. He forces his eyes to stay on Deidara’s face. “I care about it, okay? I promised I’d be different. I’m keeping my promise.”
He watches as Deidara scrunches up his face and then, after a few long seconds, he says, “Alright, fine. I choose you to be my mate. I think it was always going to be you, anyway, hm.”
At that, Obito leans forward and bites down, hard, on the gland in Deidara’s neck until his teeth break the skin. Deidara’s reaction is instant, bucking and moaning beneath him as the bond sets.
Obito doesn’t let go. He laps at the wound, tasting the iron tang of blood, and sucks at it occasionally. Deidara, to his credit, doesn’t complain. Instead, he writhes on the bed and both of his hands move to grab at Obito’s shirt.
“Tobi,” he moans. Obito knows his mind is already gone, drowning in the haze of his heat, so he obeys. He climbs onto the bed and sits between Deidara’s spread legs.
Moving with purpose, Obito reaches out and tugs Deidara’s pants and underwear down. He lifts both of his legs up to take them off. He tosses them across the room, and Deidara makes a noise of discomfort and shock.
Setting Deidara’s legs down, Obito takes off his gloves and gives Deidara’s bare thighs a gentle pat. “I’ll take care of you, Deidara,” he murmurs. “Don’t worry.”
Deidara’s only response is a soft moan and a light shake of his head.
Obito wraps his hand around Deidara’s erect cock, stroking it with a firm grip. He groans when Deidara arches at the contact. He looks his fill of Deidara’s glistening hole, displayed as it is now.
His own dick straining for some friction, Obito moves forward and presses his cock against Deidara’s cheeks. He grinds against Deidara’s warmth, unable to help the guttural growl he lets out.
Deidara comes moments later, white ropes pulsing on to Obito’s hand. Obito groans when he feels more slick ooze out of Deidara’s entrance, smoothing his thrusts. He lets go of Deidara’s cock.
Obito glances down at Deidara, who is watching him with heated eyes.
“You okay?” Obito groans out, his hips still working.
Deidara only licks his lips. He feels Deidara’s hand touch his face, his thin fingers stroking his scars.
“How…?” Deidara mumbles, but he trails off.
Obito shakes his head. Deidara bites his lip and says nothing more. There is a certain look in his eye that makes Obito hesitant, but he doesn’t stop.
He reaches down and holds himself in his hand, pressing the blunt head of his cock against Deidara’s entrance.
“Hey,” says Obito, when he sees Deidara tense up.
Deidara turns to look at him. He looks beautiful, Obito thinks. He admires the way the blush on Deidara’s cheeks spreads down to his chest.
Without having to say anything else, Deidara gives Obito a little nod and then braces himself as Obito pushes in.
The heat that wraps around him is divine. Obito sucks in a deep breath through his teeth, his shoulders tensing as he strains to support his weight. Vaguely, he hears Deidara stifle a gasp and feels him arching his back.
Obito bends down and presses his nose against Deidara’s mark, mouth opening slightly to breathe in their mingling scent. It spurs something within him. Obito begins to thrust, shoving himself roughly into his new mate’s willing body.
Deidara response in kind, arching his body to let his alpha sink in easier. He gasps when Obito bites down on the mark again, giving it an occasional suck and lick.
It doesn’t take long for Deidara to come once more. Obito grunts when he feels Deidara contract around him, at the same time that he spills between their bellies.
This time, Obito stops thrusting. He leans on his arms and peers at Deidara. Deidara is out of it, eyes staring straight across the room and at nothing in particular.
“You okay, baby?” Obito asks.
“Hm,” replies Deidara. “Just do it.”
Obito grunts. He waits for a few more seconds before picking up his pace again.
Deidara is hot, and tight, and he has never been inside an omega before. He has also never heard anyone make sounds quite as sweet as Deidara’s.
It is divine.
Obito bites his bottom lip when he comes deep inside Deidara, digging his knees into the mattress to force himself even deeper. In the distance, he hears Deidara gasp and struggle, his fingers scraping uselessly against his back.
Taking hold of Deidara’s hips, Obito tugs Deidara toward him and Deidara cries out. His knot is forming, expanding rapidly with each beat of his heart.
Deidara slides his hand down and digs his nails into Obito’s arm, making Obito hiss and let go of his hips.
“What was that for?”
“For this,” Deidara hisses in reply. The two of them flinch when Deidara contracts his muscles around his knot.
Obito clicks his tongue, but he finds that he is unable to become upset with his mate. “This is part of the mating process,” he says. “You know this.”
“Yeah, well, I haven’t really thought about how much of a pain in the ass it was going to be, hm,” Deidara replies, breathing heavily.
“Sorry,” says Obito, because he doesn’t know what else to say.
Deidara sighs, throwing his head back against the pillow and staring up at the ceiling. “It’s fine,” he says.
“Sorry,” Obito says again, because it is the only thing he thinks he should say now.
Deidara continues to stare at the ceiling. “I know,” he replies.
