7th Ko-Fi Fic Prompt :)

I’ve been asked for Alpha!Gabriel submissively pissing when he’s knotted by Alpha!Jack :3 hope you likey


When they’ve been younger, there has never been a problem with them sharing close quarters. They were both big, both very much Alpha, but Jack can’t remember a time they ever postured or became aggressive towards each other.

Now, things have very much changed, it seems. He watches Gabriel through the thick glass of the containment chamber. Prowling. The nanobots are in constant motion, creating billows of smoke that engulf his old friend as he mindlessly slides along the walls, the floor, the ceiling, looking for the smallest crack through which he could escape.

Even through the thick security glass he feels like he can smell Gabriel; the musk so thick and alien that it agitates Jack. He can feel his hackles rise, but only when he realizes his hands are curled into big fists does he turn around abruptly, looking towards Lúcio sitting behind a desk and fiddling with a big loudspeaker. His brows are pinched as he works, Tracer handing him tools as he asks for them.

“You done yet?” Jack grunts, then clears his throat when Tracer frowns at him, and checks himself, forcing his shoulders to relax and step closer towards them. “My apologies,” he mutters, then asks in a more civil tone: “How are things going?”

“Done in a few,” Lúcio answers. He hasn’t even looked up. “Just a tweak here and there and I’m pretty sure I can break through the frequency that makes those little nanobots go crazy.”

Jack nods, gaze drifting towards Gabriel who is scratching against the walls of the containment room with sharp, otherworldly claws.

.o.

Lúcio is as good as his word: minutes later, he starts setting up the loudspeaker proper. Angela has joined them to monitor the progress, her face looking about as tense as Jack feels.

Lúcio glances at them, waiting for Jack’s curt nod, then he flips the switch.

.o.

Gabriel can’t walk out of the base’s premises as long as Lúcio and Winston are tinkering on a portable device to jam the signal, but he does not seem to care too much about his involuntary confinement.

He seems docile. Mellow.

Jack watches him move about in sweatpants and soft looking hoodies, his scent spicy and thick and warm like a good aftershave; no longer as metallic and oppressive as the stink his agitation in the containment cell had made him nauseous – and Jack wants him so badly it hurts a bit.

There’s grey in his goatee and mustache, and Jack finds himself stopping in a doorway, just staring at the mess of greying curls on top of the other’s head. Gabriel never used to allow himself to grow his hair out.

Seeing him like this; moving his big, broad body slowly, without urgency – seeing him be quiet and content with the fact that he is not being controlled by an outside force for the first time in years…

It is doing things to Jack. Things like wanting to settle down in his old days. Wanting to curl up around Gabriel and pump him full of cum; get some nice, strong puppies in his belly – and that one is just plain silly, given the fact that they can’t even get kids.

Gabriel is similarly docile at first when Jack finally can coax him into his bed, but there soon is a fire of defiance burning in his dark eyes when Jack tries to roll him into his belly and mount him; easy as they’d done years ago when they were young and hot-headed.

He bites at him, then, teeth blunt and pulling up bruises at his shoulder and the swell of his bicep. Jack grunts and twists away, belly growing hot with need and excitement. Gabriel watches him like a snake; unblinking and intense.

He is lying on his back, but there is not a single submissive line to be seen in his body, and Jack shudders from head to toes, hand curling around Gabriel’s throat, thumb stroking along the strong line of his jaw.

“And here I thought I had a little pussycat in my bed,” he murmurs, “You’ve been purring so nicely for me.”

Gabriel snorts, but lets him tilt his head farther back. Jack can feel the motion of his Adam’s apple against the rough plane of his palm.

“Wanted to see what you would do,” Gabriel murmurs slowly. He stretches beneath Jack; slow and leisurely, and Jack’s gaze follows the motion downwards. He finds himself staring at the scarred expanse of unshielded, vulnerable belly – and then at Gabriel’s cock, big and thick, lying there in its nest of grey-and-black curls.

Jack can smell him; thicker than earlier. Spicy. Alpha. It makes his mouth water. He wants to lick Gabriel’s balls and sniff at that warm, cozy space behind them. Get dizzy on his Alpha smell like he’s done so many times when they’ve been younger.

Gabriel has other ideas, though, it seems; he suddenly twists, muscles bunching and tensing, grabbing Jack and curling him around – trying to make him submit and mount up in a motion that fell just-shy of playful.

Jack, in turn, begins to struggle, grunting low, adrenalin pumping – and just like that, they begin to fight for it.

They’re quiet, mostly; only their harsh breaths puffing out into the still room as the bed creaks ominously beneath their massive bodies, twisting and turning; trying to get the other beneath them just as much as they drag their wet cocks along whatever patch of skin they can find.

By the time Jack manages to pin Gabriel beneath him, his quickly fluttering belly pressed against Gabriel’s hot back, they’re both out of breath and sweating. The room is sticky with their pheromones; everything stinking of two big Alphas exerting themselves.

Jack goes nearly cross-eyed from it. He’s not used to anything anymore, it seems. His cock is pushing between Gabriel’s cheeks and he uses it to slowly hump against him.

Gabriel, as ever, takes the loss in stride. He is purring again; deeper – like a rusty engine. Almost reluctant, it seems.

“Get on with it,” he murmurs with his soft voice. He brings his knees beneath him somehow – lifts his ass up and Jack with it in one swoop. “I’ve needed cock so badly…”

He sounds like it, too. A bit weepy, almost. Jack bites at the back of his neck while he gets his bearing; gets up onto his feet in a mating press because there’s no way he could go easy on Gabriel now.

“That so?” he grunts, “Just any old dick?”

“Your old dick,” Gabriel relents after a second or two. He is panting; what little Jack can see of his dark eyes is glittering. Maybe a bit maliciously so, because when he finally starts pressing in, Gabriel suddenly bucks once more.

Whether it is instinct, or simply Gabriel’s capricious nature, Jack has to hold him down with a firm grip, growling deep in his throat as he makes the other Alpha take it. Gabriel bares his teeth at him, though only for a moment.

When he feels it – the burning slide and deep, satisfying stretch – he becomes almost sweet on Jack. He claws at the pillows, mouth open and lips wet against the fabric. He curves his back and lifts his ass like any good Omega would, and Jack squeezes his eyes shut; can’t believe how deep he can reach like this.

They fuck like this for… he does not know how long. There are no clocks anywhere; he is driven by the smell of the other Alpha; by his insides rippling wet and suckling around his cock, cushioning him sweetly the longer he deep dicks him and makes his body accept the unusual intrusion.

But eventually they become more restless; he can feel his orgasm approaching slow and relentless, his spine feeling hot and near liquid as he fucks; sharp and deep and powerful. Gabriel seems to feel it, too: he squirms, clenches around the big Alpha cock; makes soft, near hurt sounding noises in the back of his throat.

“You’re so good like this,” Jack murmurs roughly, hand reaching for the back of Gabriel’s neck; curling around it and holding him secure and still against the bed. “I’m gonna knot you,” he tells him as calmly as he can. Assured. Gabriel will not refuse, he knows.

He can feel Gabriel shuddering mightily beneath him; hears a reedy little whine simpering on a drawn-out note before Gabriel closes his eyes. Shuffles his knees a bit farther apart. Readies himself for it.

When Jack shoves in deep and rough, he smells it just a couple seconds before his knot swells quick and relentless, stretching the other Alpha almost brutally: the sharp smell of urine.

It almost dampens the delirious rush of orgasm, until the world seems to tip a bit, and it does the exact opposite.

He can hear Gabriel whimpering beneath him, eyes clenched shut, mouth still open and wet.

In a partly obscured mirror, Jack can see what is happening: Gabriel pissing a strong, unrelenting stream as he gets spread open on another Alphas cock; made to accept him. Forced to take every single inch and hold him warm and cozy until the swell lessens enough to pull out.

Gabriel pisses submissively, and it is enough to keep his orgasm going; balls pulsing a bit painful even after he’s already pumped Gabriel full of cum.

The room is reeking, and Jack loves it. His big hands are clumsy when he pats at Gabriel’s shoulders. His back. Strokes through his sweaty hair.

“Good. So good,” he murmurs with a mouth that’s gone a little numb like the rest of him. “God, Gabriel… So good…”
