Chapter Text
It’s getting harder and harder to stay away from Deidara.
Obito presses his hand against the door, knowing that Deidara is standing right on the other side, doing the same thing.
There is something quiet and sweet being whispered into the air and Obito swears he can hear his name.
He doesn’t let that taunt him.
“Deidara,” Obito says, pulling away from the door. “I’ve got more of those pills you need out here.”
“They don’t work,” comes Deidara’s feeble voice. “You know that, yeah.”
“I don’t know anything,” Obito replies.
“You can feel it,” Deidara says, “I know you can.”
“No,” Obito says. He shuts his eyes and forces himself to pay attention to his own breathing and heartbeat until they both slow to a calm.
“We seal the Three-Tails at sun-high,” says Obito through gritted teeth. “Be ready by then.”
He feels Deidara nod and utters a quiet “okay” that no one else can hear.
When sun-high arrives, Obito reappears at the foot of Deidara’s door. The box of suppressants is gone but Deidara’s scent is as strong as before. Obito licks his lips.
He doesn’t knock. “Are you ready, Deidara?” Obito asks with a raised voice.
Deidara shuffles in the room and says, “Yes.”
Obito nods and sits down by the door. Deidara does the same.
The sealing goes, more or less, without a hitch. And if anyone notices that Deidara is less responsive to Hidan’s taunts, none of them mention it.
When Obito opens his eyes next, he finds that Deidara’s door is open and he gets a lungful of Deidara’s scent, so sweet it clouds his mind. Obito’s jaw slackens and he turns his head a fraction to the right, wanting to taste more.
He doesn’t need to want for long because Deidara is suddenly on his lap, arms wrapped around his neck, mouthing at his mask where his mouth is at.
“Deidara…” Obito murmurs.
Any argument dies on his tongue when Deidara moans, a soft little thing, and grinds his hips down on Obito’s. His dick – he doesn’t even remember getting hard – pokes up against the warmth of Deidara’s body and he can’t help but grab hold of Deidara’s hips and hump up against the heat, his instincts screaming at him to bury himself deep in the willing omega.
Deidara’s grinding becomes frantic, hips stuttering as he rubs himself against Obito’s hard prick. Within moments, Deidara tenses and comes with a choked off moan. He slumps against Obito’s chest, head resting on his shoulder.
Gritting his teeth, Obito holds Deidara’s hips down and thrusts up against him, humping against his warmth until he is also spilling thickly in his pants. Deidara keens softly at the feeling.
His orgasm brings him no comfort as his dick throbs in pain, unable to knot.
Breathing heavily, Deidara pushes himself off of Obito’s chest, his previously sated expression replaced with wide, watery eyes. Obito can see that he looks more alert than before, but a glaze is beginning to reform.
“I… I’m…” Deidara tries, his mouth opening and closing uselessly as words die before he can even form them. “My…”
“Your heat,” Obito supplies helpfully. “I… I feel it,” he adds a little later.
“Yes,” Deidara says.
“I have to go,” Obito says. He pushes Deidara off of his lap, the two of them groaning at the loss of contact, and hurries to put some distance between the two of them.
“Tobi.”
Obito shakes his head. He won’t fall for it. He won’t let his instincts take over. “I can’t,” Obito replies. “You don’t want it as I do.”
“It’s too late for that, hm,” Deidara breathes, his voice barely above a whisper.
Obito shakes his head again. “It’s not too late, it’s not,” he says, more to himself than as a reply. “It can’t be.”
Deidara doesn’t say anything. His breathing is beginning to become shallow again and his eyes look distant. He starts reaching for Obito, the mouths on his hands opening and closing, drooling abundantly.
Obito grunts. He reaches out and Deidara leans closer to his body heat, but Obito doesn’t grab Deidara. He touches the skin on the back of Deidara’s neck and rubs.
Deidara moans at the contact and then he sags, limp and barely-conscious, against the wall. Obito sits there, watching Deidara’s hooded eyes and unguarded body. He could so easily…
Obito leaves before he loses his composure.
Zetsu finds him again near the cliff, no longer looking out at the sea but staring at a tree.
“Are you feeling it?” White Zetsu asks. “I think you should be able to feel it, right? I’ve read books that say potential mates can feel when the other—”
Black Zetsu grunts and cuts his other half off.
“Oh,” White Zetsu says, his mouth a perfect ‘O’ shape. Zetsu doesn’t linger long.
Obito waits until Zetsu disappears into the ground before he takes himself out of his pants. He grips the tree’s bark, fingers digging into the soft wood, and jerks himself off.
Something at the back of his mind screams at him to go to Deidara. His body yearns for it. It hurts to be away — but he forces himself to stay and strokes himself until he is coming.
His breath hitches as he paints the tree in white streaks, rubbing the last of it out. His body sags yet remains high-strung, knowing that it did not do its job.
Obito feels Deidara in the distance. He knows what he wants. He knows what he needs.
He is hard again.
Obito keeps his hands on the tree and closes his eyes. He stays where he is.
It doesn’t get better with time. He spends two days in Kamui, cock hard and body sore. The only thing in his mind is Deidara and every instinct he has screaming at him to go to him – because Deidara is also suffering.
He ignores it until one day, he wakes up feeling a little better than the previous days. He takes it as Deidara’s heat being on its final legs. Obito leaves Kamui and almost immediately, he comes face to face with Konan.
“Madara,” Konan greets him.
Obito only dips his head at her. She gives him a one-over and sniffs once. Her expression changes but everything she does is so subtle that it’s almost unnoticeable.
“You’ve been away,” she notes.
“Yes,” Obito says, “something came up and I had to see to it.”
Konan regards him, eyes narrowing minutely, and then she nods once. “Alright,” she says.
“What is it that you need?”
“Something has happened during your… leave.”
“Right.”
“Deidara went into heat.”
Obito grits his teeth. His blood surges in his veins. “Really?” Obito forces himself to say. “I thought he was a beta.”
Konan watches him, gaze flickering to his clenched hands then back to his mask, and says, “Me too.”
“Might be a, uh, a late bloomer,” Obito says, clearing his throat a little. “I’ve heard that there are betas who turn into omegas fairly late in life. Something about the presence of alphas and stress on the job.”
“Yes,” Konan says, “I’ve also heard about those.”
Obito nods and they fall into silence. Konan’s gaze on him slowly becomes painful and Obito can’t help but fidget.
“What else do you need?” Obito snaps.
Konan only hums, tilting her head up. “I was wondering if you could tell me about any stressful situations that he faced recently that could trigger his heat.”
Obito bristles. He dislikes the beta’s tune. “I don’t know of any,” he says.
“Really?” Konan asks. “You are his partner.”
“Doesn’t mean I dog him all the time.”
Konan gives him a look but Obito does not back down. “Well,” Konan says, “I think it should be your right to know that Zetsu went ahead and put the base he is at on lockdown and he’s not letting anyone in other than you.”
“That’s nice of him,” Obito says.
“I’ve also heard that Deidara was asking specifically for you.”
“You heard wrong,” Obito snarls.
“Perhaps,” Konan says, “but I am not one to judge.”
“That is correct, you aren’t one to judge,” says Obito. “Regardless, I don’t see how any of this is your business. This would have no impact on the job.”
“I see,” Konan says, eyeing him. “That is wonderful news.”
“Now, do you have anything else you want to talk about?”
“I’m afraid that is all I have to bring to the table.”
“Then leave me,” Obito says and Konan bows at the wave of his hand, disappearing into a pile of paper that flutter into the sky, blown away by the wind.
