Jason is not a heavy sleeper.
Years of living on the streets have honed his senses to be aware of any shift or scent or movement. This past year of training with Bats (and at home with Bruce and Alfred, and maybe Dick) have only sharpened this skill.
As a young omega pup, it could never hurt to be too vigilant. Even when he’s safe in his own nest, surrounded by the scents of his newfound pack and all the softness that Bruce has afforded to his son. Jason still finds it easy to wake when there’s a slight change in his surroundings.
So when Jason stirs, he first registers the long, hard length grinding against his pussy. And he immediately blinks awake.
A soft, distressed whine immediately builds up within his throat until his nose catches the scent of the Alpha right beside him. Dick. Right. Jason forgot Dick returned to visit from Bludhaven today, and he came to rest with Jason as is his usual routine whenever he claims he misses his Little Wing. Of course, Jason rolled his eyes whenever the alpha says he misses Jason, grouching irritably whenever Nightwing tugs on his cape and ruffles his hair as Robin.
Jason calms down from his startled awakening but now his heart is thumping erratically for an entirely new reason. It doesn’t take him long to realize what exactly is happening. Dick is fucking his thighs. His older brother is fucking his thighs. How the hell it got dislodged from Dick’s clothes, Jason doesn’t know. Somehow, Jason’s sleep shorts and panties have been rucked down to his knees and Dick’s own pants have come undone, and in his sleep, Dick has started to rut against him.
Dick’s cock is still buried deep between his thighs. The thick glans is sticking between them, pistoning in a slow leisurely pace as the alpha sleepily breathes in and out. A slick, wet noise accompanies each thrust and it gets only louder as Jason starts producing more slick to coat Dick’s penis.
The alpha must be having some kind of enticing wet dream because he’s been fucking Jason’s thighs at a relentless pace. The skin between feels sore and tingly, and Jason’s little clitty throbs. It feels as if Dick has been doing it for hours.
Another whine escapes him. It feels so, so good. But, Jason is a good omega and he doesn’t want to do anything that would make Dick mad when he wakes up. Who knows what Dick would do?
Jason starts wiggling in an attempt to move away. Dick’s arm around him is strong and possessive, much like his hugs when he’s awake—they engulf Jason completely.
His attempts at escape are hindered by Dick’s arms tightening around him. Jason is pressed further against Dick’s chest, and he hears a low rumble of “...Stay.” The Alpha’s breaths are now hitting the shell of Jason’s ears, and it burns.
The warm ache between his legs starts to smoulder and Jason can feel himself flush with even more shame. Dick’s strokes have somehow become more forceful while still varying in styles and length. Sometimes he does it soft and slow, gliding his cock between Jason’s pussy lips that tickles his little clitty and makes him whimper. Sometimes it’s hard and fast, short pistoning thrusts that make Dick’s balls slap against the back of Jason’s thighs and accompany the staccato beat of Jason’s heart.
The room is filled with the squelching sound of Jason’s slick. His pussy is sopping. He can feel the sheets beneath him growing damp from the trails of slick dripping down his thighs. The amount of pre that’s licking from Dick only makes his glide smoother. His glans kissing Jason’s clit each time he passes.
Dick’s alpha musk makes Jason feel lightheaded. The sharp spicy notes trapping him and keeping him pliant against Dick’s chest. It doesn’t stop the terrible feeling brewing in his gut though. Dick is asleep and here Jason is taking pleasure from him! The guilt bubbles up heavily in his chest, but not enough to dampen the sudden surge of lust that comes from Dick’s ministrations.
Jason decides to do one last final escape attempt. “Dick, Dick!” He urges, squeezing at the arm wrapped around his waist. He pushes at Dick’s face behind him, growling in frustration when Dick just buries his face further into Jason’s neck. “Wake up, you need to wake up,” he starts digging his nails into Dick’s flesh. “Dick, please, wake up!”
It doesn’t work.
Instead, Dick still seems trapped by his wet dream as he moans into Jason’s ear. “...No… I’m not done… So good...” He starts laving his tongue at the side of Jason’s neck, stimulating Jason’s scent glands and making the omega whimper louder. “...So sweet, my omega…”
At his words, Jason shuts his eyes tight. Omega… Dick must be thinking about Babs, or Wally, or Kori. One of the older pretty Omegas that surround him. And here Jason is, taking advantage of his big brother.
Jason is such a bad omega.
He can’t let it happen.
Jason starts pounding at Dick’s arm, rearing back and kicking at him with his legs. “Wake the fuck up NOW, Dickhead!” As he moves, Dick suddenly bends forward, curling over Jason with his bulk and height. Jason’s kicks means that his legs have shifted angles and with Dick moving at the same time, there’s only one thing that happens: Dick’s penis catches onto his pussy lips and enters.
“Oh, oh,” Jason gasps.
Dick pulls out. Jason exhales. The head of Dick’s cock continues to catch onto his pussy lips, threatening to breach once more. It ruts against him, slicking Jason up further. Jason curses, he doesn’t know how he’ll get out of this now.
The rutting doesn’t stop. The alpha’s penis continues to tease Jason’s cunt with entry. Thankfully, or unthankfully, the angle means it mostly stimulates Jason’s clit instead of going inside. Jason doesn’t know which one he prefers though as his core aches with emptiness with each thrust.
“Dick,” Jason growls out. “If you can’t fucking stop…”
A thought occurs to the omega. If Dick comes, then he’ll most likely let Jason go and then Jason can leave, wipe off the mess, and pretend that none of this happened.
He could probably think of a better strategy but it’s the best plan Jason’s currently got so he pushes through. Finally gaining strength and resolve, Jason starts squeezing his thighs together, creating the perfect vice to grip the alpha’s dick. The change in pressure seems to stimulate the alpha in his sleep because Dick starts to go harder, an alpha rumble building in his chest until it vibrates loudly against Jason’s skin.
It's working! Jason starts to slowly shift his hips.
Then, as if mocking Jason for taking this chance to relax, Dick abruptly changes position, angling his hips upwards and spearing Jason on his cock. “Ah!” Jason cries out, his pussy accepting Dick’s cock so easily. “...Wait!”
He can’t help how turned on he feels at the fact that Dick’s cock just pushed right in, brushing past his pussy lips and settling deep within his cunt. Dick just keeps on going, hammering further in while Jason starts to drool. His pussy feels like a fleshlight, Dick just pumping in and out without a care for Jason’s whines and whispered pleas for him to stop.
Guilt starts to sour Jason’s omegan scent. This wasn’t how he wanted it to go… Sure, he knows his crush on Dick was hopeless from the start. The age gap and their precarious relationship as brothers means Jason has to stop his omega from reaching out to his chosen mate.
And now, here he is, taking advantage of Dick and losing himself in pleasure. Dick just continues to use him relentlessly, groaning and murmuring random words that Jason can’t pick out.
His cock is just perfect. It feels Jason completely. He’s sneaked glances at the alpha whenever they shower after patrol. But eyeballing it doesn’t mean Jason can gauge the exact size, not when he scampers away and tries to hide his embarrassed flush with bluster and insults whenever the alpha looks at him. It feels like it’s 12 inches at least, filling every inch and crevice of Jason’s omega cunt.
Jason doesn’t want to know what it’s like to never have it again. Too bad, it’s just for this one night. Jason can't bear it. “After this,” Jason swears, lips trembling as he tries to bite back his moans. Fuck, it feels so good, and yet, Jason knows he can't have this. Not when Dick doesn't see him that way. “I promise I–I’ll let you go, Alpha… ‘m sorry… I—oh!”
And then he hears it.
Dick moans, his lips brushing the shell of the omega’s ears, “Jason.”
Oh.
Oh!
Jason. That’s his name! Then that means… Dick is dreaming about him. Jason’s the Omega in Dick’s dream!
That means it’s okay. Dick wouldn’t be mad. In fact, Jason could help him. The omega in him chirps at the revelation. If Dick is dreaming about him, then Jason can make him feel extra good. Just as good as Dick is making him feel now.
Jason clenches his cunt experimentally, gasping at the way the organ rubs against his walls. Dick groans once more, probably liking the added pressure as Jason grips him. Since he enjoys it, Dick would probably finish faster. Maybe Jason should squeeze him more.
Jason starts moving his hips in earnest, meeting Dick’s own thrusts as he starts fucking himself back on the alpha’s cock. He can’t help but wish that Dick was awake so he could hear his voice more clearly. So far, the alpha has just been mumbling into Jason’s neck, licking at his scent glands all the while. “...Feels so good, Jay… My little wing… My pretty ‘mega, feels so… mine…” What would he say if he was awake? Would his words be just as sweet?
By now, the entire room is saturated with both Dick and Jason’s scent. The lustful sounds of their coupling echo loudly in the dark bedroom. Jason’s heart feels full. The knowledge that Dick dreams of him and the thorough pussy fucking he’s receiving only means it’s a miracle Jason even lasted this long.
He cums, the orgasm ripping through him and setting his insides alight with fire. A plaintive omega warble leaves Jason’s mouth and he tilts his head, craving a bite. His cunt clenches incredibly tight around the alpha’s cock, and Dick’s breathing grows heavier.
The hold he has around Jason squeezes the remaining air out of Jason’s lungs as he’s crushed against Dick’s chest as he comes. The alpha’s cock is shoved up to the hilt inside of him, pulsing hot, heady cum inside Jason’s omegan channel.
There is no knot. It’s almost impossible for alphas to knot outside of their rut, after all. Still, Jason can’t help but squirm harder on Dick’s shaft, wishing there was an added stretch to keep him full. He could take Dick's knot if he had the chance, his pride would ensure it. The alpha’s dick continues to spasm, sending wave after wave of cum into Jason’s belly.
It seems like Dick has been cumming forever. His cum is so warm. Jason feels so full, so good. Dick has been nosing at his neck and Jason just knows he smells like a proper, claimed omega. He can feel himself release his own happy notes into the air, and he greedily hopes his scent settles on Dick when he wakes up. So he knows how good Jason felt afterwards.
Dick sighs as soon as he finishes, squeezing Jason once more before his hold relaxes. Jason shudders as the alpha’s soft cock falls out of his pussy, kissing his little clitty goodbye as it leaves. Immediately, alpha spunk begins to drip out of Jason’s hole, alongside the copious amount of slick Jason’s been producing the entire time.
Jason just lays there while Dick continues sleeping, his cunt used and throbbing. He shifts and checks under the blanket to see his pussy filled with cum. He huffs, How the fuck is he gonna clean this now? Jason levels a small glare at Dick, feeling silly and petulant at the fact that the alpha was asleep the entire time.
Trust Dick to always make Jason clean up his mess!
The omega leaves the bed and rinses himself quickly. As much as he’d like to carry Dick’s pups one day, being Robin is still the magic of his life. He looks back at Dick, eyes still closed and face set in a relaxed expression. Jason closes his eyes as he lays back down, burying his head against Dick’s chest to breathe the alpha in.
Since Dick said his name… Jason will ask about it tomorrow. His inner omega thrills at the prospect of Dick actually liking him back. It was a good thing he woke up! He’s definitely going to hold the Dickhead accountable for this.
If there’s one thing he learned as Robin, it’s to never let go.
…
Dick smiles into Jason’s hair, a deep rumble escaping him as he scents the sleeping omega.
Mine.
