fanfic prompts

[xax]

so every so often i do a fanfic prompt post! this is one of them!

gimmie a story prompt with a setting + some characters and/or a situation, or fetish, or w/e, and i'll see if i can write a short porn fill. fandom stuff only, no OCs but 'generic character from the setting' is fine. no real restriction on which fandoms, but you have an increased chance of getting a fill if it's something i'm familiar with & have written before. i definitely won't fill everything b/c i'm real bad at finishing things.

prior fill post here for reference

EDIT: okay i think i'm done taking prompts now. i'll maybe write a few final fills and then i'm done for the time being. ty everybody who commented!

well, matt finally takes the knot here.

---

Taking Garurumon's knot was a considerable challenge. Taking Garurumon's dick had gone shockingly easy, actually. For all that it was an immense, arm-sized spear of animal cock, well, people got fisted all the time, and Garurumon's dick had the advantage of being tapered. Taking the tip wasn't any trouble at all, and then it was just a slow, continual slide as Matt rocked deeper, until he'd reached his limit. It took more than a few times before he could bottom himself out on Garurumon's dick, and Matt tried to not feel like those were all trial runs -- it made sex a little weird if having it felt like failure -- but he had to admit that getting emotionally invested in being able to take Garurumon's dick had made things a little weird.

They'd actually, uh. Talked about it. Not, like, awkwardly, just that Gabumon had said, "You know, Matt, you've really been wanting to take Garurumon's knot, yeah?" and things had gone from there.

"Uh, yeah, I mean-- of course. I don't know, I know... I know I can get a little fixated on things. Sorry if it made you feel like, I don't know, that I'm only with you for your dick."

Gabumon had laughed. "It's not that. You can want my dick as much as you like. It's just..." That had been after, uh, the second time Matt had torn himself open. That was awkward, and it meant no sex for a week or two while his guts healed up. "It's really hot to see you try so hard to take my dick, but not when you actually hurt yourself."

It had taken some time, Matt had said, for things like 'I don't think I can take it' to go from hot phrases to hear right before some huge digimon slammed their whole dick into him, to actual things he could say when he didn't actually think he could take it. He had, uh, a lot more experience fantasizing about digimon sex than experience with actual digimon sex.

They'd gotten some inflatable dildos. There were plenty of weird animal dick dildos for sale, and with the increase in digimon there was a booming market in digimon-dick dildos too. They'd taken a look at some company's Garurumon and WereGarurumon models; Matt had gotten enough experience by that point that he could agree with Gabumon that they were both totally unrealistic. Also, they both had the knot as a perpetually-hard lump at the base of the dildo.

"The whole point of a knot is to keep the dick inside!" Garurumon had complained. "It defeats the whole purpose if you could just slam it in there!"

"Yeah, I know," Matt had said, still idly squeezing Garurumon's dick with his thighs. Garurumon was on his back, Matt curled up against his chest, legs tangled around his unsheathed dick. Matt was holding his phone up to Garurumon's face, letting him stare at the dildo models upside-down. "I mean, I get it intellectually, but the fantasy is, y'know, all about getting used like that. Also if you're drawing porn nobody wants to draw only internal shots all the time; they wanna actually see the thing."

Matt had been riding the tip of Garurumon's dick, hole soft and shockingly loose afterwards, and the dregs of Garurumon's load was still oozing down onto his belly. Matt could curl his ankles around the base of Garurumon's shaft and feel the barest throb of his knot, invisibly sunk at the base of his dick.

So, anyway, the Garurumon dicks weren't really a good training aid, but Matt had ended up getting one anyway, even though it'd cost ¥20,000. Even the extra-large WereGarurumon model was considerably smaller than Garurumon's actual dick, and the extra soft model was squishy enough that he thought he'd be able to take its knot.

The point was, Gabumon had said, to train Matt's guts. To get his ass used to something real big inside it, and to train him out of the reflex to clench around something huge, not so much to stretch out his actual asshole in a big gape. Well, in a gape beyond what was needed to take the fist-sized bulk of his actual dick. The thing with getting knotted, for real, was that Garurumon lasted up to a half-hour knotted, and, as he said, it didn't really sound like a fun time to get knotted and then have Matt injured and bleeding, getting more and more torn up, for an entire half-hour. So they wanted the first time to go off without a hitch, which meant a lot of practice runs.

Between that and the general hassle required to prep for anal when he was gonna have a few litres of cum shot into him, it took a while. Matt got really used to jerking off Garurumon while he sucked on the tip, since they could do that-- well, once they did that literally in a secluded part of a park. Matt had dunked himself in a nearby pond afterwards to clean up most of the evidence. Bringing out WereGarurumon... well, the first time had been a challenge mostly to find somewhere with enough privacy to has sex with somebody two stories tall.

Even though WereGarurumon was only a little bit taller than Garurumon rearing up on his hind legs, his dick... well, there was a reason why all the dildos were tiny. Anything realistically-sized would bankrupt their manifacturers with silicone costs. WereGarurumon's sheath and balls were crammed tight into his leather pants, and... well, the first time Matt got to sit between WereGarurumon's legs, using all his strength to haul his belt through a beltbuckle the size of his chest, and finally getting his reward of WereGarurumon's sheath bursting out into the open, fur damp with sweat, head-sized cocktip peeking out of the leathery folds of his sheathtip, just being able to rut his entire body against WereGarurumon's torso-thick shaft was the real reward. WereGarurumon had laughed, voice booming and guttural, and cupped his entire body with one huge hand, pressing him down across his cock, letting Matt stroke it with his arms and legs, head sloppily glazed in his thin wolf pre. Matt had stopped thinking about getting knotted, or even getting WereGarurumon to cum, utterly lost in the sensation of stroking the mammoth cock, feeling it pulse against him, feeling hot pre wash over his chest and trickle down his bare skin. He'd humped himself to completion, cumming with a moan with is dick jammed against the heavy, smooth lines of WereGarurumon's titanic cock.

That was a big part of him getting less goal-oriented with sex. As it turned out, just having sex could be an enormous amount of fun if he came into it with an open mind, instead of setting out, first thing, with the conscious goal of taking Garurumon's dick this time.

Not that he didn't also still do that a lot. It just made the training, letting Gabumon fuck him with their inflatable dildo, more enjoyable if he stopped thinking so much and let himself sink into the process more. Once he'd let himself get immersed into it: ass grinding down against WereGarurumon's bulky sheath, pre gurgling down his chest in a continual spill as he writhed and keened, embarassing noises ripping their way up his throat as he gasped for breath against WereGarurumon's sloppy cocktip, both hands wrapped around his shaft in a bear hug. When WereGarurumon actually came, it was with a bellowing roar and a harsh throb from the base of his shaft, knot expanding out in forceful pulses until it spread his thighs, legs locked around its shuddering bulk as a slimy wash of WereGarurumon's watery wolf cum rained down on him.

Which wasn't to say that Matt didn't end up taking Garurumon's knot. Just that it took several months to get to, between everything else.

When Matt had first gotten fucked, he'd been amazed at how his ass had felt afterwards: hole puffy and soft, opening up again shockingly deep and wide at the slightest push even days afterwards. Riding Garurumon's cocktip was the same, only moreso: leaving him with a heavy, plush hole, that wetly pouted open after Garurumon had glazed him with his latest load. Training himself not to clench down on Garurumon's knot was something he had to do a lot more intentionally: get Gabumon to get out the inflatable dildo and fuck him with it, and then slowly inflating it inside him, inner walls stretched tight around the fat, hard bulk -- and Matt making sure to take it, leaving his hole loose and guts slack as he mentally adjusted to the fierce, constantly-increasing burning from his raw, tightly-knotted ass.

The night Matt ended up finally taking Garurumon's knot, they hadn't even really planned for it. Matt had cleaned himself out deep, and Gabumon had digivolved out to Garurumon, cock already unsheathed, flushed and heavy across his underbelly. He rolled back, showing his belly, and let Matt climb on top, lubed hole eagerly and, after months of use, easily slurping over his cocktip. Matt groaned, slick heat flooding his guts as Garurumon gushed pre inside him. He rutted back, fucking himself deeper onto Garurumon's dick, his own cock stiff and sliding through the huge digimons lush fur, slowly fucking a slimy furrow across his underbelly. Matt whined, on his knees on Garurumon's belly, slowly rocking himself deeper and deeper onto Garurumon's dick. He knew the angle to hit to slide Garurumon's dick into his guts, a little twist of his torso as he ground his ass back, and with a raw, intense pressure his guts flexed open, letting Matt sheath himself down onto Garurumon's massive wolf dick.

He groaned, arching back so he could stare down at the bulge of his stomach, cock visibly warping his taut belly, sliding back and forth as he fucked himself. Garurumon whined, hips jerking up in fractional jerks as Matt pushed himself down, each thrust tapping his cocktip an iota deeper, until with a dizzying sense of fullness, guts tugging and unspooling inside him, Matt slid down to the base, asshole pressing against Garurumon's sheath with a wet squelch. He let out a shaky keen, one hand on his dick as he erratically milked out a slimy mess of pre, and slowly rocked in place, letting Garurumon pick up his thrusts, fucking him in slow, shallow thrusts that got deeper and deeper as Matt groaned and encouraged him on, until six inches of cock were pounding into him with each thrust. Garurumon's sheath piled up between his asscheeks, folding over itself in a fuzzy pile as Garurumon jabbed down, sinking down to the absolute root.

They'd done this before. But two days ago, Gabumon had fucked Matt through a body-spasming orgasm with his inflatable knotted dildo, tying him tight until Matt was sobbing, half-hard dick wetly pissing out pre as the dildo's knot had ground down constantly against his burning prostate. Matt's guts still ached, inner walls slick and loose, and when they both felt Garurumon get close, the first shudder of orgasm running up his shaft, making the entire thing pulse and fatten.

"Garurumon," Matt whined. "Please, please! C'mon, knot me!"

"Matt!" Garurumon groaned, name inarticulate through a long, howling groan. "Are you sure?"

Matt sat back onto Garurumon's dick, sheathing himself utterly on his cock, groaning again as he cupped his bulging belly, knot throbbing hard against his inner walls. "Yes! Please!"

Garurumon's shaft hardened inside him, spongy flesh stiffening into a fat, bulky shaft, and with it, with each pulse that ran through his enormous wolfcock, his knot surged fatter. Matt keened, grinding his ass down, panting for breath as Garurumon's knot surged and surged, burning hotter and hotter. Pre squelched, gurgling down his inner walls and squirting out around Garurumon's burgeoning knot. As the knot grew, pre came in thinner, but more pressurized squirts, messily painting the backs of Matt's thighs, until -- the flow of pre started building up inside him, squelching around Garurumon's throbbing knot, forming a sloshing reservoir inside him.

Then Garurumon came, properly. He howled, hips freezing as he strained to stop himself from driving deep. Matt sat across his underbelly, ass aching, knot pounding, as a wet heat blossomed inside him, pouring down his shaft and adding to the sloshing, squelching mess dammed up inside him.

Matt groaned, belly aching more and more as cum filled him up. He had to sit up straight, releaving pressure on his aching guts; simply leaning forward put a painful pressure on his swelling guts. He needed all the space within him to take Garurumon's load.

"Don't clench," Garurumon said, as they awkwardly twisted around each other. One of Garurumon's paws pressed against his shoulder, helping Matt pivot around the immense knot inside him. The smooth flesh slid across his inner walls, leaving a burning imprint, and the ache only vaguely subsided when he'd flipped around 180 degrees, leaving Matt able to lean back against Garurumon's underbelly and take some of the pressure off his bloating guts. Heat trickled inside him, fluid slurping along the rim of Garurumon's knot. He was pretty sure he wasn't bleeding. The spill of Garurumon pissing out thin, watery spurts of digicum inside him went on and on, even as his aching guts cramped and gurgled and his belly grew and grew. Matt whined, body flushed, cock sluggishly oozing pre. Garurumon's cock felt like a spear stabbing him through, a red-hot spike throbbing inside him over and over, more and more. It hurt. Matt wasn't sure if it was a bad kind of hurt. He lay back against Garurumon's underbelly, dizzily centering the sensation of being filled: each spurt too weak to feel directly, but the constantly-increasing mass of cum filled him more and more.

They probably should've timed when Garurumon's knot started swelling. It was 11:43 now, looking at his digivice, but that meant nothing. It was 11:57, and Matt was a shaking, sweating mess, belly bloated and pregnant-looking, guts burning, assflesh raw and stinging, before Matt started feeling the knot soften. Garurumon whined, cock weakly flexing as he pissed out the final dregs of his load, and -- after however-long it had been, Matt had to fight the impulse to wrench himself off, doing what would definitely tear up his straining guts. He just kept laying there, ass burning, as Garurumon's knot slowly shrunk. Cum gurgled, hot trails wending their way along the walls of his ass, and then with a wet squelch started oozing out of him, pouring in thin, watery trails all down his thighs. Matt let out a releaved groan, guts rippling as he let cum gush out of him, coming in heavier and heavier gushes until with a final slurp Garurumon's softening cock spilled out of him, knot a barely-there swell. Matt fell to the side, rolling out across his haunch, still half-impaled on Garurumon's fat shaft as he finally let himself clench, groaning hard at the fierce burn that burst across his aching flesh. He reached back: his asshole felt spongy and soft, flesh easily yielding to his fingers, and even as slimy digicum slowly gurgled out of his guts, Matt sunk the crest of his hand into his own ass: fingers curling around Garurumon's softening shaft, knuckles grinding against his burning flesh, as he half-fisted, half-jerked off Garurumon, other hand sloppily stroking himself off.

Matt came with a groan, finally spilling off of Garurumon's dick entirely, leaving him a sweating, cum-drenched mess cuddled up against Garurumon's side, gaped asshole spraying out cum in watery bursts. Garurumon twisted above him, nose sliding down his side, slobbery tongue lapping at his raw asshole.

"You're only bleeding a little," Garurumon said. "Higher up in your guts. It should be fine." Matt just groaned. "How do you feel?"

Matt let out a shaky laugh. "Full. Achey. Ask me in an hour if I ever want to do this again, because right now the answer's 'no', but-- yeah, in an hour it'll probably be 'tomorrow'."
