Dick knew that his heat was coming. He isn’t an idiot, he knows that when you present as an omega you’ll go into heat within six months. He did the reading though — not only would it be better for his body to not go onto suppressants, but within a year or two his heats would shorten and even out. That means he’d be able to patrol more in the long run if he didn’t suppress his heats down to the three a year, week long events that most omegas decide to go through. He also doesn’t want to become reliant on suppressants just in case anything ever happens and he can’t have any, but that's a secondary reason.
All things said and done, Dick expected his heat. He even planned for it. He had nested out his bed, bought a toy and some cooling lube, and even persuaded Alfred to help him put a small fridge in his room for electrolyte waters and healthy snacks.
What he didn’t plan for, however, was how the toy doesn’t help when the alpha he’s in love with is asleep just down the hall smelling like a sunny forest that Dick just wants to rub all over like a needy cat.
Dick creeps down the hall with his softest blanket from his nest wrapped around him. His brain is half fogged up with heat but he can still think, can still control himself. He isn’t some brainless sex puppet or anything out of a dramatic bodice ripper; he’s just a teenage boy with a bad idea, and the part of him that usually keeps those bad ideas in check is currently panting and mewling for his second father’s hands all over his sensitive scent glands.
Bruce’s door is unlocked because he never locks it, even when he really should. He doesn’t lock it when he brings people home, he doesn’t lock it when he’s jerking himself off, and apparently he also doesn’t lock it when the omega in his house is filling the entire hallway with honeysuckle scented ‘breed me’ pheromones. Dick closes that unlocked door silently behind him and that rarely used lock clicks into place with finality.
Bruce’s bedroom smells safer and more inviting than Dick’s own nest, and under any other circumstance Dick might have just stolen a pillow or something and squirreled away in his room to shove it against his face or his needy cunt for the night. Tonight, however, Dick has a bad idea, and he’s pretty sure that this is the one time he might be able to get away with it.
Dick knows he isn’t some mindless sex puppet, but Bruce probably doesn’t.
The teen crawls his way onto the bed carefully, pulling Bruce’s blanket down until the man’s mostly nude body is revealed. It isn’t winter time so he’s just in his boxers, and those are also easy to pull down when Dick goes slow and gentle. His heat scent is either already affecting the man or Bruce is having a pretty nice dream, because his cock is already halfway hard when Dick gets the boxers out of the way.
Leaning against the alpha’s legs, Dick opens his mouth and sucks the head between his lips. Flattening his tongue against the slit, the omega has to hold back a hungry groan at the musky, salty taste. He sucks the head, hand playing with the loose skin around the base of Bruce’s cock where he knows the knot will grow. Bruce is much bigger than his toy, and it has Dick drooling around his cock in a way that lubes it up and makes it easier for Dick to take more and more into his mouth.
The omega honestly can’t tell which part of him is wetter by the time Bruce is fully hard.
He wishes he could keep going with his mouth but he needs to have the alpha inside of him before the man wakes up. After all, if he’s already balls deep in Dick it will be harder to argue against the omega. So with one last longing suck to the dripping head of his mentor’s cock, Dick gets his knees under him again and spreads his legs around the man as he shuffles up his body. His nesting blanket is still curled around him, and between Bruce’s scent and his own all mixed up in his nose Dick feels like he’s in heaven — and thats before he presses the alpha’s tip right up against his toy-fucked hole and starts to slide down.
When Dick was first talking himself into this as he was crying over how empty he felt, he told himself that just the tip would be enough. He told himself he’d just fuck himself to completion on the very top of his dad’s penis and it would have to be enough. As Bruce’s cockhead slides inside of him, though, Dick knows that he won’t be able to keep that self-made promise.
The way it feels, slowly being filled to the brim as he lowers himself on the man’s cock, is nearly indescribable. The overwhelming burn of discomfort starts to abate with every inch that slides inside of him, the haze over his mind thinning a little as a different type of fuzziness encroaches on him. He can practically feel Bruce in his stomach even before he bottoms out, but when he does it feels like the tip brushes against something electric inside of him. Dick shivers like his whole body has been strung through with a rip-cord.
Dick claps his hand, still tangled in the edge of his blanket, across his mouth when a moan bubbles out of him. His eyes flash up to Bruce’s face, finding the alpha with furrowed brows and flaring nostrils but still — for now at least — with his eyes closed. It urges Dick forward, the fear that the man will wake up and pull him off before he can get his fill.
Making sure his legs are bent and braced in the proper way, Dick begins to slowly bounce on his alpha’s cock, his whole body twitching and shivering with pleasure as the overwhelming heat that’s been boiling him alive is fed. He knows he can do this for a while with how built the muscles in his thighs and core are, but god what he wouldn’t give to be pushed down into a presentation arch and railed within an inch of his life by his dad. What he wouldn’t do for Bruce to hold him down and knot him and fill him up over and over until he’s dripping and can’t even think anymore.
A soft mewl escapes the omega at the thought and he smothers his blanketed hand against his mouth a little harder to try and suppress any further noises.
The omega speeds up his riding, chasing the coil of pleasure in his stomach that has replaced the awful cramps from before. It feels like his whole body is getting tighter and tighter the more he hops and swirls his hips on the man’s cock, but the knot he’s craving, the knot he needs to climax properly during his heat, doesn’t seem to be swelling. There’s tears of frustration welling in the corners of his eyes as he braces his hand on Bruce’s abs and tries to ride a little quicker, clench a little tighter, do anything to call the alpha’s knot forward.
That’s when the alpha groans. “Dick? Fuck!”
Hands scrabble for his hips, trying to stop him, and Dick finally uncovers his mouth to scratch at Bruce’s wrists. “No, no! I want your knot, Dad, please.”
“God,” Bruce swallows loudly. His eyes are dark and shocked when Dick lifts his teary gaze to look at the alpha. “Son, you can’t just… I was sleeping, Dick. That’s not right, sweetheart.”
He’s holding Dick still in spite of the omega’s desperate fingers tugging at his wrists and Dick sniffles. “You would’ve sent me back to bed if I woke you up. I would have been alone with that stupid plastic knot in my dumb room where it doesn’t smell safe.”
Thumbs roll against his hipbones, the older man trying to comfort him even now. “I know your heat is really scary, Dick, but you can’t have sex with people when they’re sleeping. It’s not consensual, son.”
Unable to pull Bruce’s hands away from where they are holding him in place halfway off his cock, Dick scrubs his blanket fisted hands against his teary cheeks. “It isn’t, I didn’t– ugh! I didn’t come in here because I was scared, I came in here because I needed my alpha and he was ignoring me and sleeping!”
The alpha’s brows slide up in surprise. “Your… Dick, sweetheart, I… I’m not your alpha.”
Dick’s pretty sure that if that were true and Bruce really believed it, he wouldn’t sound so sad about it. The omega lowers his hands to glare harshly at the man underneath him. “You’re a moron.”
“That’s not very nice,” Bruce says seriously.
“You’re not very nice!” Dick hisses, frustration coming back with the stupid heat cramps that have replaced his impending orgasm. “It hurts, and I love you so much, and you smell like mine, but you’re being.. Being…” he can’t find the word and it makes him even angrier so he just smacks Bruce’s hands around his hips again, trying uselessly to try and shove them off.
The alpha grunts. “Dick, you have to stop. This isn’t right, son.”
“I don’t care,” the teen growls, baring his teeth at the man like he’s got his own alpha sized fangs to challenge with instead of the nubby, omega sized ones he does have. “I want you. Why.. why can’t I have you?”
Bruce hesitates. His brows are furrowed again, something behind his eyes shines through, a fragile little crack that Dick catches and attacks like a wolf, leaning forward to press their bodies together the best he can. “Don’t you want me, Dad? Don’t I smell good?”
He presents his neck in submission and Bruce’s lips twitch, fangs flashing for just a moment before the man clenches his jaw. “Dick,” he says, voice thick.
“Tell. Me,” Dick all but growls, squeezing tightly around the hard length still halfway inside him.
Dick’s whole world goes topsy turvy, Bruce rolling them to slam the teen down into the mattress. That little bit of cock inside him that was keeping him half-tethered to planet earth instead of the fiery sun of his heat gets pulled out of him and the omega wails. He lets go of his nesting blanket to slap and claw at the man for the injustice, only to be flipped over on his stomach. He tries to get his knees under him, tries to throw an elbow back because if Bruce won’t fuck him then the least he can do is fight him.
A wide palm slams down between Dick’s shoulders, shoving him down against the pillows, hips still in the air so close to the mating arch he’d been craving just moments ago. The hand slides up, knotting hard in his hair to drag his head to the side again and Bruce noses into his throat, fangs scraping against his sensitive scent gland as the man speaks. “Is this what you want, Dick? Want me to bend you over and take everything from you?”
A bolt of lighting goes through Dick’s body and the fight slips right back out of him as fast as it came. He wiggles, spreading his legs a little wider, arching his back a little further. “Please? Please, Dad, I want you so bad.”
Bruce groans into his throat, breathing in as much of Dick’s honeysuckle scent as he possibly can. “You shouldn’t have tempted me, sweetheart.”
That cock that Dick has been craving prods at him again, rubbing across his hole like the man is playing with him before the head slides in. Once the tip is pressed in, Bruce positions his other hand on Dick’s hip and without giving the omega a chance to breathe he slams home. He thrusts forward so hard that the slap of skin against skin reverberates around the room and Dick moans, fingers tangling in his nesting blanket.
Bruce fucking into him is a very different experience than the one Dick had when he was chasing his release on the sleeping man’s lap. It’s so much better like this, so much faster and firmer and more fulfilling. Dick doesn’t have to choke down his sounds anymore; he can mewl and moan to his heart’s content as Bruce licks over his scent gland like it’s some sort of ambrosia.
“Alpha, feels so good, want your knot,” is one of the more coherent sentences that falls out of the omega’s mouth as Bruce fucks the cramps right back out of him. That tightening coil of pleasure winds through his belly again.
A rumbling sound escapes Bruce. The base of his cock is slowly thickening as he fucks the teen, his knot building with his climax. They’re both winding closer and closer, noises reaching a peak. The alpha’s rational self has been thrown out the window and all that’s left is a man at his basest, chasing his climax and the pull of his omega’s heat.
Bruce’s knot fully blows, locking inside of the teen on his next thrust in, and his teeth clamp down, piercing the thin skin of Dick’s scent gland. Dick shakes apart beneath him, sagging like his strings have been cut as he gushes his orgasm around the knot he’s been coveting since before he even presented.
Dick loses time during the high flying of being knotted for the first time and when he reaches awareness again they’ve been turned onto their sides. His nesting blanket and Bruce’s duvet have been pulled up around them, making him purr in contentment at their combined scents. Bruce even has one arm fully wrapped around his abdomen, keeping him pressed tight against the man’s body so the knot doesn’t pull uncomfortably.
The other hand is tracing his tingly scent gland.
“You mated me,” Dick whispers, awed.
“We can break it after your heat,” Bruce whispers, voice sounding wrong somehow. “You haven’t bitten me back so the bond isn’t complete. You can break it.”
A growl rips out of the omega, stopping his purrs in their tracks. “How dare you! You are mine. If you didn’t want to be then you shouldn’t have bit me!”
Bruce sighs, burying his nose in Dick’s hair. “You’re in heat, Dick. You don’t have the mental aptitude to make those kinds of choices.”
“You really are a moron,” Dick sniffs, rubbing his body back against Bruce’s and clenching around his knot. “I won’t break it. I wanted you to be my alpha before I even started this dumb omega business.”
The arm around him tightens and Bruce presses a kiss to the mating bite. “Alright… but we still have to talk about it when your heat is over. Promise me that, son.”
Dick rolls his eyes but he can’t help but smile. “I promise.”
