not-so casual batman fan

I was wondering what you would do for the aftermath of an accidental mating for Bruce in no pack au? Say he and another character got hit with a spell or ivy's bs and end up spending Bruce's heat together.

I think I did this for Hal....or was that just pack bonds...

Who cares I'm always down for npa

Bruce stares at Clark in horror. A hand slowly moves up to cover the junction of his neck, still sluggishly bleeding even hours after Clark's fangs sunk in and mated him. "Clark—"

He inches forward and Clark scrambles back on the bed, making for the door, only for Bruce to tackle him back down to the mattress. Clark writhes, trying to get away without hurting him more and Bruce straddles him, then pins his wrists. The sheets pool around his waist, but Clark can't appreciate the sight, not when he can't tear his eyes away from the blood.

"Clark. Clark you've got to calm down."

"I b-bit you. Oh god I bit you."

"Clark—"

"I need to go—" He falters when Bruce growls at him, and it hits stronger than ever before. Because they're mated.

"Clark. You have to calm down." Bruce shakes his head, flicking his hair out of his eyes, and a few droplets off blood drop down, landing on Clark's chest, and he baulks. "You can't leave, you'll be arrested the second someone sees you." He lets go of one of Clark's wrists, and gently runs his thumb over the dried, crusted blood falling from his lips down his chin. "We need a plan."

"That is the plan, Bruce." Clark flips Bruce and gets off the bed, making a break for the door. He doesn't get halfway across the room before Bruce yells behind him and he falls to the ground with a moan of pain. "Shit, shit," he gasps, swearing more than he usually does in a week as he claws his way back to the bed. Bruce drags him up and into an embrace, shivering in his arms.

"That is not the plan, Clark, because it isn't an option." He tucks his head into his collarbone and Clark folds over him, cherishing the closeness with one part of himself and hating it with the other, because he forced Bruce into this. He's trapped them together, for a month at best, the rest of their lives at worst.

"Bruce, I broke the law. All alphas are required to wear muzzles during a rut, unless both parties have filed written consent to be mated."

"Clark, Ivy's pollen doesn't exactly give time for a trip down to the city council office, we barely managed to get to a safehouse. So stop feeling guilty, we need a plan. Backfiling the forms with our signatures will be easy, and we've had a public friendship it's believable we could have courted and not revealed it to the public."

"B."

"You've known the kids for years, and are around them a lot, we could make them think they just didn't realise you were courting me and earning their appeal so—"

"We're not telling the kids?"

Bruce doesn't answer, and Clark cautiously slides a finger under Bruce's jawline and tips his chin up, so Bruce meets his eyes. "I am— was an unmated omega with nine alphas under my purview. Do you want to tell them I was mated without consent? They won't kill you, Clark, but their instincts will demand it." He pauses. "Even if I'm not pack. Dick nearly tore out Talia's throat when he was a teen. Selina was driven out of Gotham for months when we were courting because the kids attacked on sight, and were still uneasy with her after we stopped courting. I don't want to see what they'd do to you if they knew I didn't give explicit consent."

Clark tilts his head down, pushing his shoulders back, and rests their foreheads together. He wants to blame it on the mating bond that being able to smell Bruce's rolling storm scent calms him down. "Fine. Fine, okay."

"J'onn can be convinced not to reveal what he gleans from our minds, but if we act well enough we can probably fool the rest of the League."

"There's one problem," Clark points out. His hand on Bruce's back slides up, and the tips of his fingers brush the edges of the bloody wound on his shoulder. "The bite is one-sided. Without my own mark, no one will believe I did this for any reason but to control and manipulate you."

Bruce is quiet, then sighs, and his breath tickles. "Clark Kent, Kal-El of Krypton, do you consent to a mating bite, and the bond and duties that come with this mark?"

Clark swallows, and feels strangely breathless for someone that doesn't need to breathe. "I consent."

Bruce opens his mouth, and Clark watches in real time as his fangs protract. A calloused hand cups his face, turning it away, and a slow exhale warms the skin of his throat. He leans down, and Bruce bites into his mating gland, their half-bond giving him the power to penetrate invulnerable flesh.

Colours explode across his vision, and his senses spread out across the entire world, before narrowing again, and all he can hear is Bruce, gasping quietly as their bond settles into place, his heart racing in his chest.

Clark wraps his arms around Bruce and plasters them together, newfound instincts washing over him and he exhales softly into Bruce's hair as he releases the bite.

New mates cannot leave each other's side for an average of four weeks after the bite. The need for proximity persists, while lessened, for months afterwards, depending on the couple.

Clark wants to just live in the moment, to ignore the fact he and Bruce weren't even courting, to ignore how Bruce doesn't return his love, to ignore everything wrong with this, but he can't.

Then a thought occurs to him.

They can avoid homicidal intent by lying to the kids that this was planned, but Clark forsees another issue. How will Bruce's kids react, when they don't want him, but don't want anyone else to have him either? And now Clark has him, heart and soul for maybe the rest of their lives, and will have to compete against potentially the most fucked up pack he's ever met.

"Relax," Bruce murmurs into his neck, and Clark nods. "We'll figure this out."

The chaos, the repurcussions, the kids trying to contain their envy because now Clark is Bruce's pack, and they're not, resenting each of them for it. The Justice League, the world reacting to such a sudden mating, the two of them putting on the performance of their lives to pull it off and struggling with the lines blurring between their feelings and the reality of it. Both of them feeling guilty for the bond. Both of them feeling guilty for how the kids take it.
