Kid was always bigger than you, no matter what, but when he transformed he was just that much bigger. Taller and wider, you were sure he gained a foot in both directions at least. Hot hands were on your thighs, thick fur blotting out what little light was in the room as golden eyes watched you carefully.

Metal pipes kept you in place, fitted into brackets and holding you in a position. You were on on your back, legs in the air, knees by your chest. There was a curved leather backing supporting your back and giving you something to absorb the pounding that was coming. It also let you see well enough that you could watch his throbbing cock, unsheathed, blood red, and dripping, twitching and bobbing. Like it was panting, desperate to be buried inside you.

The knot at the base seemed entirely too large, but you couldn't suppress your desire to know.

Kid leans down, the deep rusty maroon of his fur parting to show off an impressive row of teeth. Long pearly white fangs that dripped with hunger almost as much as his cock did.

"Wha-what are you doing?" You question in concern. His eyes flit up to yours as he continues to move lower until his snout is by your slit. You watch it twitch as he sniffs, taking in your scent and painting embarrassment across your face. "Oh god, don't-."

"Delicious." Kid growls, and in this form, this massive dire wolf form that seemed almost too big for the room you were in, his voice really is a growl. He always has gravel in his voice, often softened by the warmth of honey, muted slightly by a velvet undertone.

But in this form there's no honey or velvet. It's stones and bark and pine - harsh, scratchy and oddly cool.

Or maybe you were so hot and bothered his breath chilled your skin.

"You smell divine all the time, little feast." He continues, breathing in deep. "But like this... fuck." He opens his mouth, licking the long, heavy and wet tongue along your labia. You gasp in pleasure and surprise, this tongue is rough compared to the usual.

Rough palms are against your ass, clawed fingers splayed over your thighs as his thumbs carefully spread your pussy open. You don't even get a squeak of protest out before his tongue dives in.

The metal bars hold you in place, and keep Kid from putting too much weight on you - bondage and safety all in one. His cold nose is against your clit as his tongue pushes deeper and deeper into your cunt. Sweet sounds are ripped from your lips as he seems on the edge of literally devouring you.

He pauses and growls a time or two, his fingers flexing as though he wants to do something different, but stops himself. But he finds all the places he was looking for, and after a couple minutes the orgasm is coiling in your stomach and you're gasping and whining and trying to warn him that you're going to cum, but as your toes curl and your body shudders against the metal bars you're sure he knows.

He pulls his tongue out slowly, ears twitching at every shivering gasp, eyes so wide they're barely rimmed in the amber gold of his irises as he soaks in every flutter on your face. Slowly, carefully, he licks your folds, almost taking care not to send any unexpected shivers through you. Even the softest ministrations were turning you on, however, and at the same time they helped you relax.

"Can't... finger you," Kid husks, flexing his clawed hands and reminding you both he can't retract them in this state. "But you keep getting wetter." Even with the change from human to dire wolf, you can see the pleased grin on his face.

"Heh, wolf-fucker." He teases.

You stick out your tongue. "I'm a Eustass Kid fucker, you ass. I don't..." You look away, the expression on his face is too intense right now. "Want anyone else."

Kid grabs onto the bars holding you in place and you can hear his palms twist against the metal. The claws on his feet are carving grooves into the wooden floor and he's struggling to control himself. He warned that sometimes it was hard to keep his cool when he transformed. The extra senses could be overwhelming, but there were instinctual compulsions that he didn't have as a human.

"... Kid?"

"M'fine." He says through clenched teeth. After another moment he lets out a long slow breath, and straightens up, grinning down at you. How he managed to flash that arrogant charmer crooked grin of his with the face of a wolf was beyond you, but by the gods.

"Let's get to what my greedy little Mouse has been looking forward to all this time," he holds onto the metal bars, positioning himself so you can watch him entering you without his fur getting in the way. The tapered tip helps, but Kid the human is not small, and Kid the dire wolf is just as thick and veiny, with a bulbous head just below the tip.

Almost like a mini knot.

He eases in slowly, listening to your sigh, and watching your face for any signs of pain. He pulls back and pushes in going a little deeper. Slowly he works himself in like this, growling when he gets about halfway in and forcing himself to pull back and ease back in.

Brash, arrogant, rough, demanding - Kid was a lot of things in the bedroom, but he never accidentally hurt you.

"Fuck," you both husk the swear as his knot presses against your lips. He's only a little bit bigger in this form, the biggest difference is the knot, but right now you're not sure it's going to fit.

He moves slowly, a growl rattling against his chest, as he makes sure that he's fitting without hurting you before he begins to move faster. There's no pain, each slow and careful thrust is sending shivers of pleasure through you and soft moans are breaking against the back of your teeth. You're trying to be a little quiet, concerned that if you make too much noise he'll struggle to keep control.

"Don't..." He growls, thrusting into you roughly and spilling the moan from your lips. "Don't deny me, your sounds." He huffs, hands tight on the metal bars as he starts to move more.

So he says, but the pace he sets pushes the air from you, even with the metal rig providing you some stability. He leans forward, hands on the heavy table you're bolted into place on. There's nothing for you to see but fur as the thick mass tickles your skin with each thrust. Your breathy, desperate whines are muffled by the thick coat, but he doesn't seem to mind.

Maybe because the sounds are sinking into him, instead of being withheld from him.

"Kid!" You gasp and he shifts enough to look down at you, slowing a little. "Close," you gasp, toes curling as his shifted position is hitting something that's making you see stars. "F-fuck!"

He keeps himself in that position, adjusting his speed until you started squirming in the rig. Beast or man, he was ruthless when it came to bullying all your sensitive places. You cry out your pleasure, cumming against his cock, sweet sounds turning into gasping whimpers as he keeps paying attention to the same needy spot, making you ride the first orgasm into a second one.

When you cum again he slows just a little, nuzzling against the side of your face and licking your neck. Sweaty and shivering you return the action, nuzzling back against his face, humming at the thrill his attention was sending through your skin.

He leans back, carefully pressing his thumb against your clit, his eyes staying trained on what he's doing so he doesn't accidentally scratch you. They steady pace and pressure on your clit brings you to the brink again fairly quickly, and Kid keeps you there.

The toothy grin on his face every time he brings you down from almost cresting, then the way he mocks your whine when you whimper knowing you're being denied again. You can't even truly complain, you don't hate it. You know he's making you a sopping wet mess to make taking his knot easier.

Knowing didn't alleviate the burning need that was building up inside you, however.

"Kid, please!" You gasp, having been denied again. Frustration was outweighing your concerns and you needed that intimidating bulge inside you.

He straightens out, pulling out entirely before pushing back in. His hips are slamming heavy thrusts into you, as he licks your face, growling a little as the entire assembly groans from the force of it. It's bruising, but in a dull faraway sense. Pleasure is forefront in your mind, and as his breath gets heavier and rougher he engulfs you in fur again.

You can feel his hands and feet clawing deep gouges into the wooden bench and floor. He growls loudly, one last desperate thrust shoving the thick knot into your cunt. Hot liquid floods your insides as he empties inside you. The rough fur off his lower abs are coarse against your clit and the deep stretch and rush of being filled is enough to push you over.

Kid ruts into you, teasing your clit with his fur and sending electricity through you with every throb and twitch of his own orgasm.

"Holy shit." You huff into his fur as things start to calm down and you can find enough air to talk.

"Yeah," Kid sighs. He pushes in deep, making you gasp from the sensation of it, and the feeling of thick cum leaking out. He pulls back and the strange pleasure as he eases his knot out is almost enough to make you cum again. The wet pop leaves you feeling terribly empty, but Kid gives you soft licks as he helps get you out of the rig.

"I thought we'd be stuck like that for a while." You muse as he helps slowly ease movement into your limbs before getting you on your feet.

"If I couldn't push in enough to break the seal, yeah." He slowly starts to transform back into his human form. The knot's still throbbing at the base of his cock, and you imagine it'll be a while before it goes away.

He lifts you up when he's done changing, pulling you into a deep kiss. He peppers you with kisses, his hands wandering over you as he makes sure you're not scratched or bruised too badly. A few more kisses have you giggling and Kid grins.

"Definitely like kissing you more than licking you." He says, cradling your head in his hands and stealing a couple more kisses before he lifts you up into his arms. "Wolf snouts aren't really made for it."
