Chapter Text
There's a low purr rumbling in the back of Tim's throat. Has been for a while. He's lying on his back in his nest, the soft sheets and comfy pillows tucked around him as the scent of heat and happy pup lies thick in the room. The soft orange light of evening pours in through the windows, staining everything it touches with a citrus tinge. Damian is curled up on his chest, his lips wrapped around a nipple, soft sucking sounds filling the silence as he greedily feeds. They’re both naked as the day they were born. Heats make the skin so hot, sensitive and prone to irritation that Tim would rather have as little clothing rubbing up against him as possible. Tim idly strokes at the hair on the back of Damians neck, leaning down and pressing a kiss to his pups forehead. "Good pup. Sweet pup." He babbles contentedly.
It was a strange little armistice the two of them had but it was one nonetheless. Damian's initial rejection had stung. A lot. Not only that but he'd gone out of his way to make him feel like he didn't belong. Like he wasn't Pack. In response he shut Damian out just as hard, refusing to scent or touch him at all if it wasn’t necessary, spending his heats at Titans Tower or one of his safehouses, stomping down hard on any omegan instinct that told him to coddle and care. His body had other ideas. Having the scent of a pup around caused Tim to start producing milk. He hated it because it made him sore and at the time he'd had no intention of nursing the little demon child who'd tried to drop him to his death. And Damian hated it because he could smell the milk that Tim was denying him purely out of spite.
It went on like that for a while with the two at each other's throats and nobody willing to give in. That was until Dicks overzealous scenting accidentally triggered an early heat that Tim had no choice but to spend at the manor. He still remembered the quiet creak of his bedroom door that night. The look on the poor boy's face, led by his nose to Tim's nest. Damian's scent radiated shame, need, angry, lonely, hungry. So many conflicting emotions scrunched up in his tiny face. He could scarcely meet Tim's eye when he opened his mouth and whispered "...Mama?"
At that moment, Tim didn't see the prideful and arrogant Damian Wayne standing at his door. Instead he saw a hungry little pup who needed him. Who needed an omega.
Tim had welcomed Damian into his nest that night, had breastfed him for the first time. The boy was ravenous. Tim had had to pop him on the head a couple times to get him to stop biting him so hard but once the little pup figured out how to latch properly he calmed significantly. Tim remembered how the boy visibly relaxed against his chest, how small and vulnerable he looked in his arms, the swell of warmth and affection he suddenly felt for Damian. He had refused to see any of his alphas, snarling at them if they got too close and spending his entire heat petting and preening over his new pup.
Because Damian was his pup now. There was no getting around it. He was the omega of the family and through the feeding he and Damian had finally formed a pack bond. So this became their new little ritual. Whatever they may be to each other outside of the nest, inside it they were pup and Mama.
Tim is drawn out of his thoughts by Damian shifting against him. "Comfy, puppy?" He asks, dreamily. Damian doesn't answer him, simply suckles and continues to reposition himself. Before he'd been lying on his side, his legs tangled with Tim's. Now he's sorta laying on his chest and straddling Tim's thigh and...oh. Tim sighs and smiles accommodatingly down at Damian. It's another Puppy Rut.
He'd read up on this after the first time it happened. Apparently it wasn't uncommon for Unpresented pups in the presence of packmates going through heat or rut to experience a rut-like state called a 'Puppy Rut.' Damian did this occasionally when they nested together. It wasn't really a big deal and Tim didn't wanna embarrass the poor little pup. He just had to let him grind it out and it was done. And then they would go back to nestling like usual. Tim places another kiss on the top of Damian's head as he feels the pup start rutting against him. "There you go, puppy. Make yourself feel good." He praises, rubbing Damian's back with one hand and carding fingers through his hair with the other.
Damian lets out the tiniest little whimper around the nipple in his mouth, milk dribbling down the side of his cheek as he grinds his stiff little cock into Tim's thigh. "M-Mama!" He whines, lifting his head and turning those big green eyes up at Tim. Where normally they're so full of scorn and defiance, here and now they're soft and wet, timidly asking 'is this ok?' His face is all red too and Tim feels just a little bit bad for thinking that it's cute. "Shhhhh. Mama's got you. Mama will give you what you need, my sweet pup." Tim murmurs, guiding Damians mouth back to his tit. Damian latches again without issue, eagerly drinking as he humps without rhythm against Tim's leg. It's adorable really. Tim is starting to understand why Dick spoils him so much because, when they nest together at least, he finds it hard to deny Damian anything.
"Goooood pup." He coos, tracing little figure eights in Damians back. Their bodies are hot and sweaty pressed together, making it easy for Damian's clumsy thrusts to glide easily over Tims thigh, leaving trails of pre-cum in their wake. Damian's pace quickens, gaining a bit of confidence and he lets out something akin to a growl, or as close as a pup can come to one at least. Tim tries not to laugh and instead he wraps his arms around him and does his best to fill his scent with pack, safe, Mama. His little pups scent is all muddled now with want and please and mine. He has no doubt that Damian will grow up to be an alpha. Call it Omegan instinct or whatever but the snarling possessiveness he tends to show in these moments have 'baby Alpha' written all over them. Not that Tim'd mind if he turned out to be wrong. It'd be nice to have another Omega or Beta in the house to share his heats with.
It doesn't take long. It never does. Soon enough Damian is whimpering and cumming over Tim's thigh and Tim is shushing him and whispering soft words of praise into his ear. "Such a good puppy. Did so well for Mama. Yes, you did. Such a good boy."
Exhausted, Damian unlatches, his belly full and his arousal satisfied. He yawns and stretches and then moves to curl up against Tim. Tim nudges him away, making Damian pout and whine in protest. "Not yet, puppy. We need to clean up first. Then we can sleep." Tim instructs. He paws tiredly for the drawer of supplies Dick and B filled up for him. Damian whines again and tries to wriggle his way under Tim's arm. Tim turns back to him annoyed. "Puppyyy, stop!" He says firmly.
Damian pouts even harder but when Tim turns away again he isn't disturbed. He grabs a towel from the drawer and wipes them both down, tossing the cloth away to be washed later. That taken care of, he lays back down and opens his arms, inviting his pup back in. Damian gladly takes the invitation, snuggling smugly into Tim's chest.
"Spoiled pup." Tim chuckles, his lids growing heavy.
Damian chuffs softly in reply, the sweet puffing sound lulling Tim into a light sleep.
