Chapter Text
The pleasure wakes him, wave after wave pushing through him. Keith groans into the bedding, moving with it, letting himself linger in the half-asleep sweetness of it. He’s already so close to the edge and it feels amazing, like it’s been going on so long.
And then something pushes into his hole, slender but hot. A tongue.
The sleep falls away and Keith jerks awake, flails trying to turn and see who’s—
But it’s fur, blue. A snout, the wild eyes of his wolf.
Fuck, he’s been licked by— had almost gotten off to—
“Hey, boy,” the snout is still down between his legs trying to nose his thighs that have snapped together. Keith flushes down his whole body. “That’s not, no.” He’s deeply regretting having slept with no clothes on right now.
He pushes at Kosmo, but the wolf is not to be deterred. He snuffles at Keith, nudging more urgently.
Keith sits up and stumbles up off the bed. Tries to escape.
The wolf is quicker. Before Keith can get more than a foot toward his bathroom, he’s pushed over by the heavy mass of fur. He hits the ground hard, his palms and knees smarting.
“Fuck, ow Kosmo!”
The wolf is practically on top of him, and Keith tries to shoulder the mess of fur and legs. “Get off you big idiot!”
He doesn’t. In fact, the wolf gets more on top of him, on his back, and Keith collapses under the weight. He slams down onto his forearms, hitting his bottom lip on his teeth. The bright taste of blood floods his mouth.
But there’s something more concerning, all the high alarm bells in his brain start going off. Because Kosmo isn’t just on top of him, he’s— he’s—
Mounting.
There’s no other word for it. Keith’s on his knees, ass in the air and Kosmo is draped over him, front paws digging into his sides.
Keith makes a sound of distress and tries to claw away, but there’s little traction. The wolf is huge and heavy and holding him in place.
“D-don’t!” Keith cries as he feels a wetness bump the back of his thighs. As the wolf begins to hump him. “Kosmo!”
Keith wriggles when it gets close, when he feels… it… smear against the folds of his pussy. He can’t let it, can’t, can’t let this happen. He’s— he squeezes his cunt tight as if by will he could keep it closed.
It does nothing but incentivize the wolf. The claws dig in and the humping gets more aggressive, more targeted. Twice the— the thing— grazes him, slides through his slick folds and glances off.
Kosmo dances on his hind legs to adjust the position, pushes Keith a little forward so his spine dips and he’s better presented.
“No,” Keith wails when it slides through again. It’s seconds away, any thrust could be it. It’ll be irreversible.
Keith pulls and pushes and tries to get away, but it's no good. He arches his own hips for leverage, to give one last good push and—
That slick, hot cock just slides right into him.
Keith makes a sound of shock, of disgust. He’s so wet from sleep, from the fear, and so there’s no pause. There’s just a too-full and heavy slide, a cock bigger than anything Keith’s ever taken breaching him.
His cunt pulses, clenches, doesn’t know how to take it.
But that’s just it: he’s just there to take it.
The moment Kosmo gets in, he begins to fuck Keith hard. There’s no build up, no getting used to the enormous cock, it’s just a wolf fucking a bitch’s pussy.
Keith cries as the cock thrusts into him. It’s too much, way too much, but there’s no mercy from the animal on him. It goes on and on, the obscene sound of his wetness, the way his body is moved by the intrusion, the huffing snout now pressed into the back of his neck.
And then something in Keith’s brain starts to leech pleasure. Even as Keith denies it, that wolf cock battering him is just the right size to hit all his spaces. To make his cunt clutch with the urge to keep it deep.
He can’t like this. It’s wrong, bad. He doesn’t understand how it’s happening, how he’s getting wetter for this. Kosmo may have gotten on him, but his body is going out of its way to lubricate. To make it easier for that cock to slide deep.
Keith cries as Kosmo begins to fuck him harder, jackhammering into his tender hole. Wetness is dripping out of him every time the wolf pulls out, and then there's a squelch as the cock thrusts back in. He's being used just like a bitch, like some cocksleeve for the animal. It's humiliating and awful and there's nothing he can do.
The pressure on his hole starts to get more intense, and it’s then that Keith remembers about wolves on Earth. Kosmo isn’t from Earth, but if the sharp pain that begins with every thrust is any indication, space wolves also have knots. Fuck!
“Don’t, don’t, please!” The words are useless but he feels so useless just there on his knees letting it happen. He doesn’t want to take a knot, doesn’t want this… this beast to come inside him.
The horror of it bursts on his belly. Kosmo is fucking his cunt good now, hard and fast and preparing to breed him. To fill him up. Fuck, he can’t— this can’t be happening— !
He feels the cock gets thicker, Kosmo jerking the swelling knot in and out of his hole. It’s disgusting, moving his whole body as it abuses his whole.
But Keith's pussy starts throbbing like he’s seconds away from coming. He can't, he just cant-- !
Then Kosmo shoves once and twice and a third time in rabid succession. It’s so painful, barely fitting that last time, but then it does because Keith is drenched. An impossibly large knot pops into his hole for the last time and stays there. Locked.
Keith groans as the cock inside him starts dumping its load. It shoves deeper and deeper, so deep it has to be coming directly into his—
Oh god, oh god—
Keiths own orgasm cuts him off then. He whines, miserable as it overwhelmed him. As his body betrays him by fluttering around and milking that knot. As Kosmo continues those tiny thrusts into the deepest part of him, coming thick and heavy.
He feels ashamed, violated. He doesn’t know how this happened, how he let this happen. Already he knows he can never tell anyone about this. He came from a dog fucking him. He’s sick, wrong. What would the other paladins think?
Kosmo shifts behind him but stays in. The knot makes him stay. It’s different from a dog, but not in any better way.
Instead Kosmo snuffles at his hair, licks his bare shoulder and neck.
When the knot does eventually come out, Keith tries not to hear the slick sound of it. The soft pattern of come dripping out of him. He can only imagine what he must look like.
A well-used bitch.
Already Kosmo is hopping back up onto the bed, relaxing down into the covers. As if nothing happened.
Keith lies there still on his knees, come leaking down his thighs. He doesn’t know what to do.
