Dick sipped his coffee quietly as he glanced out the ceiling to floor kitchen windows of the Wayne Towers apartment.
The sun was just rising and it had only been four days since he'd found Damian writhing on this same floor by the stairs, consumed in his first heat and desperate-
Dick quickly blinked away the images of Damian clutching at him, face flushed in pain and pleasure, eyes dilated and unseeing. He'd been practically naked, hips canted up and legs thrown wide to welcome any intrusion. Any Alpha.
He heard a crack and felt the ceramic of his cup give way and cursed as he quickly released his death grip on his mug and made his way over to the sink before the burning liquid could splash onto the marble floor.
His fingers slipped on the running rivulets and the cup shattered at the bottom of the chrome sink. He stared blankly at the white shards as they glinted with the sun's rays and at the swirling dark brown of the coffee as it slid deeper into the black hole that would lead it into the sewers.
The coffee was dark, as dark as Damian's skin and just as slick.
Dick took a deep breath, trying to inhale the fumes of the strong coffee instead of the damp musk in the air, the dark spices that spoke of need, tears and sex. He felt the pull low in his gut as sweat started to dampen his skin and his mouth watered with saliva, ready to give his Omega the hormones he needed, he craved, in his heat.
He quickly dunked his head under the faucet and cranked the cold water tab and let the torrent crash onto the top of his head while he panted, eyes slightly glazed.
Four days. Four days he'd been here holed up with Damian. Kissing, biting, spreading the teen's thighs and knotting that slick heat as the boy cried out in pain and poisoned pleasure. His voice was horse and he constantly begged for more, faster, meaner, harder-
Dick took deep, long breathes as the freezing water fell across his face.
After that first time he'd called Oracle and told her that he and Damian were going to spend some 'brotherly bonding' time together. They were taking a break. No costumes, no villains, no family. He'd asked her to let Bruce know. Since no one had busted through the door, or a window, apparently she'd delivered.
He hadn't told her about the heat. About Damian. About how he'd found the boy splayed out on the floor trying to rub himself off, his scent permeating the air so thickly that he was glad that their apartment covered the top two floors of the Tower or he was sure another Alpha would have found him. Claimed him. Fucked him.
He felt a growl grow deep in his chest and clutched at the counter, trying to hold himself still.
He'd been worried, scared, that Damian had been hit by Ivy. But Ivy couldn't produce that smell-that scent that was desert, spices, mint and swirled around in a deep musk screaming 'Fuck Me'! at the top of it's lungs.
He'd freaked and was trying to examine him, ignoring the way his body responded instantaneously to the smell and that his saliva started to slick his mouth.
Damian had hooked his legs around his waist as he tried to hold him down; gibberish falling from his lips between his mewls and gasps for more.
It wasn't until Damian had started screaming for someone; anyone-to knot him that Dick had known.
He closed his eyes and let the images come. Opening Damian with his gloved fingers, the slick coating him. His gloved hands wrapped around those corded wrists as the body twisted away and toward him all at once. His body so hot and tight, grasping him in to the point of pain, legs spread wide to accommodate his thrusting hips. His mouth wide open as he made begging noises in the back of his throat while tears spilled down his flushed face.
He'd watched him come from just being fucked, his head thrown back to reveal his Omega gland. With one bite he'd be able to change Damian's body's chemistry. Make him unable to stand another Alpha's taste. His body incapable of accepting any hormones, other than Dicks, during his heat or it would drive him literally insane. It would bind the boy to him forever.
While he plunged into that willing body, his knot expanding, making Damian cry out as his seed released into his hot depths he'd sunk his teeth into the hot, throbbing flesh. He'd let his saliva sink into the swollen gland, laving it with his tongue, enjoying how Damian's sent changed. It swirled and dipped and mixed with his.
Now, when anyone scented him, they would know to whom he belonged. If anyone touched him they'd only live long enough to regret it.
Dick withdrew his head from the sink and turned the tap off.
He'd known exactly what he'd been doing when he'd marked Damian.
When they had been partners, Batman and Robin, they'd been amazing. Even as difficult as Damian was, when he was with him it felt like a part of him that he hadn't even known was missing was now complete. It almost destroyed him when Bruce had come back and forced him to leave.
Damian would never know how hard it had been for him to walk away. Yes, he'd loved being Nightwing, always would, but he'd loved being with Damian more. With Bruce's return there had been no real reason for him to object taking back his cowl.
In the beginning, Damian had lamented how much he'd wished he'd worked with his father instead. How subpar Dick was as Batman.
He knew Damian didn't hate him anymore, maybe even had a growing fondness for him, but he couldn't stay between him and his father. If he had stayed he'd always be in the middle and they'd never be able to bond.
Not to mention, as much as he loved Bruce, he was an Alpha. They'd had problems when he started presenting and they'd just rubbed each other the wrong way. Each one wanting to be in charge. It was only one of the reasons he'd gone and joined the Teen Titans. Their relationship had gotten better with space.
If he'd stayed with them, Dick was sure they'd fight, try to tear each other apart. Damian was still a child and had no scent marker of Alpha, Beta or Omega, but he was still Family. Even Family had a hierarchy and there could only be one leader. Since Bruce's death Damian had been his family, his partner and in his territory. Everything in him had screamed mine when Damian had been in the same room with Bruce.
It would have been unfair. It would have been a disaster. So he'd left and regretted every minute afterward.
The feeling of mine had never really left, but he'd never had any reason to act on it, no reason to suspect.
He shook his head and wiped the back of his hand across his face and threaded his fingers through his hair as he slowly made his way back up the stairs toward the bedrooms.
They'd all waited for Damian to present as something-after the age of thirteen the thought of Omega was dismissed. Omega's presented earlier than all the other castes. If he'd been a breeder he would have shown the signs before then.
Dick had been disappointed in a way he didn't understand, but not really surprised. Damian was a very opinionated and arrogant boy and wouldn't have dealt well being seen as 'less'. Even though the archaic ideas of Omega's being weak and needing protection has slowly faded there were still those that held onto the old ways.
Still, he'd sniff the air around Damian whenever he was near, waiting.
He'd hoped that Damian would be a Beta, that way they wouldn't have to fight over territory, have those undercurrents of dominance every time they got near each other. Even with Alphas that he liked it was still there. There was a reason he couldn't stay in Gotham for long.
He smiled as he slowly opened his bedroom door and savored the heavy musk in the air.
Damian was curled with the blankets on the bed, dark skin covered in sweat and bite marks, the white of his scars standing in naked relief.
He'd never seen anything so beautiful.
Dick sauntered over to the edge of the bed and slowly sat, careful not to wake the sleeping boy.
He dipped his fingers into the dark, inky black hair and silently stroked the back of Damian's skull, enjoying the boy's slight arch beneath his fingers. He closed his eyes and took a deep breath.
He sorted through the scents in the room, focusing on Damian, searching for that almost milky smell to tell him that they'd conceived.
He smiled when he couldn't find it.
He opened his eyes, hand still firmly carding through Damian's hair as he eyed they boy's flat stomach.
One day he'd be swollen and waddling around their apartment, glowing and scenting of baby. Their baby. One day.
Dick lowered himself behind Damian, nuzzling the back of his neck as he enjoyed the cool sheets against his super heated body.
Damian was still only fifteen; he needed to come to grips with being an Omega. He needed to enjoy his childhood a bit longer, no matter how much he protested that he wasn't a child. He needed to come to terms with Dick being his Alpha and what that meant.
He let out a small growl as he lightly bit the Omega gland beneath Damian's jaw on the side of his neck.
He was his and there was no running now. It was a forever kind of thing.
