Impmon's got needs, and he knows just the dino digimon to give him what he wants.

“Oh for fuck sake!” Impmon exclaimed, jumping higher into the tree to hide himself from the approaching humans.

As he crouched amongst the leaves waiting for them to pass by, his purple erection throbbed between his legs, demanding his attention. There he was, having a nice relaxing jerk when he was interrupted by a group of noisy humans heading down the path in the park. The little fuckers were taking their sweet time walking by, and until they were gone Impmon was stuck with a raging erection demanding attention he couldn’t give. He wasn’t going to be able to stay hidden up there and jerk off at the same time. Not only did he have a tendency to get rather noisy, but there was no way the shaking leaves and branches wouldn’t get their attention.

Fuck he wished they’d hurry! Even as needy as he was, his erection was starting to flag. He’d been so close to his peak that the sudden stop was ruining a very promising jerking session. He’d been thinking of this sexy Gaomon he’d banged the last time he was in the digital world. The guy had been so sexy, and that canine cock of his had hit Impmon’s insides in all the right places. He’d enjoyed pinning the pup down and teasing his knot with his ass while they were tied together. It had been so much fun watching him squirm and whine while his cum filled Impmon’s ass.

Those memories were enough to keep him at half-mast even as the humans slowly strolled away. His purple penis was still dripping precum, but he didn’t want to settle for his hand anymore. Thinking about that gaomon - or the two gazimon the time before that - had him yearning to feel that aching fullness and deep stretch that he could only get from a big knot getting shoved under his tail. But where could he go to get what he needed? It would take way too long to get back to the digital world, and even then he’d still have to find a guy with the right equipment to give him what he wanted. What to do…

His eyes drifted further into the park, and that gave him an idea. Looking around to make sure the humans were gone, Impmon leapt from his hiding spot and started moving through the trees. He didn’t give a shit if they saw him, but flashing his manhood to a bunch of humans wasn’t something he wanted to be bothered with. Not when he had the perfect place to get the relief he was craving. It wouldn’t take him long to reach the cave where that pineapple head stayed, and based on the looks he’d gotten when the dino digimon had been all hot and bothered, Guillmon had just what Impmon needed.

Reaching the cave and moving closer, he could hear voices coming from the cave. It wasn’t that human Guilmon was partnered with; it was someone else. And from the way the other one was talking, it sounded like a digimon. Peering inside, Impmon’s face split into a wicked grin. Guilmon wasn’t alone – there was a gabumon in there with him. And when he got a look at the two very male digimon and what they were doing, only one thought went through Impmon’s mind.

He’d hit the jackpot.

The two digimon were sitting towards the back of Guilmon’s cave, facing each other with their legs spread. Impmon licked his lips at what lay between the other males’ spread thighs. Gabumon was slowly stroking his erection, and it was everything Impmon enjoyed in one perfect package. The other male’s cock was good and thick, a canine cock with a nice big knot at the base and a pair of smooth yellow balls that promised a nice hot load inside anyone lucky enough to ride the digimon’s dick.

Guilmon’s penis was equally appealing, in part because it was so different from Gabumon’s. While it wasn’t quite as thick as the other digimon’s, it was longer, and while Guilmon had a knot as well, his penis also possessed a number of ridges that circled his length and would feel incredible giving that little extra stretch to some lucky guy’s ass every time the red dino moved in or out. Lacking proper fingers, Guilmon was trying to toy with his cock, but was clearly having a harder time of it.

“You’re longer, but I’m thicker,” said Gabumon. “And my knot is bigger.”

“Knot?” asked Guilmon, tilting his head in confusion. “What’s that?”

Impmon rolled his eyes. Looked like he was as slow as ever. How could anyone be so incredibly dense about their own body!? Impmon couldn’t help himself as he moved forward into the cave, his purple erection bouncing with each step.

“Geez, pineapple head, you really aren’t too bright, are you?” said Impmon, noticing happily how the eyes of both males immediately locked onto his erection, following it as he moved. “He’s talking about this.”

Reaching forward, he grabbed Guilmon’s erection around the base, giving his knot a good squeeze. He smirked as the dino digimon moaned, his hips thrusting up into Impmon’s grip, a drop of precum beading at his tip. Letting go, Impmon swiped it up with a finger and licked it off.

“Not bad.” He glanced at the two digimon, thinking quickly. Eager as he was to try Guilmon’s cock, he thought it might be better to start with Gabumon’s. And since he didn’t have any lube handy…

“Let’s see if you taste as good.”

Dropping down between Gabumon’s legs, Impmon grabbed his thighs and held them apart before slurping the other male’s penis into his mouth, running his tongue along the bottom as he started to bob his head. He moaned happily at the taste, hollowing out his cheeks and sucking a little harder, looking up and smirking around his mouthful as Gabumon moaned, a cute blush building on his cheeks. His moans grew even louder when Impmon’s hands left his legs, one rubbing his chubby belly while the other rolled those smooth yellow balls in his hand.

After about a minute, Impmon slowly let Gabumon slide from his lips, giving the tip a parting kiss.

“Delicious.” He gave Gabumon’s knot a squeeze and the digimon - who had been leaning back on his hands - shuddered and collapsed on his back as his arms gave out, the unexpected spike in pleasure turning him to jelly. “But there’s only one way to tell how good a guy’s cock is.”

Impmon climbed on top of Gabumon, kneeling over him and lifting his tail. Reaching back, he grabbed Gabumon’s cock and lined it up with his entrance, his purple penis jumping at the feeling of a warm cock against his pucker and the anticipation of feeling it inside him. Looking back over his shoulder at Guilmon, Impmon sank down onto that thick dick, moaning as it stretched him out. Guilmon’s cock was leaking heavily as he watched, but Impmon’s attention was drawn back to Gabumon, the cute digimon moaning loudly as Impmon’s tight tailhole swallowed his cock until his knot was pressing against his pucker.

“Fuck yeah, that’s nice,” sighed Impmon, shifting around to make Gabumon’s cock hit all those hidden spots inside him that had him dripping over the other male’s belly.

He smirked at the way Gabumon gasped at feeling the tight grip of his ass. Lifting himself up, Impmon started riding Gabumon, slowly working that thick dick in and out of his rear. Fuck, it was so much better having a hot cock to stuff his ass with than having to try and satisfy himself with a hand and fun memories. And the cutie beneath him certainly seemed to be enjoying himself, his hands sliding up to Impmon’s hips, helping to pull the other digimon down on his dick. Gabumon was even starting to thrust up to meet him, Impmon’s tight ass teasing the top of his knot, eager to feel that big bulb of flesh inside him.

Of course, that didn’t mean he couldn’t tease Gabumon a bit first.

Impmon moved his hands to Gabumon’s, making the other digimon tighten his grip, his thumbs stroking over Impmon’s hips while his fingers dug into the wonderful ass riding his cock. He started squeezing down on Gabumon every now and again, shifting the angle of his ass to shift Gabumon around inside him and hit new places that had him making a mess of the other male’s belly. Not that Gabumon seemed to mind, or even really notice. He was lost in his own haze of bliss.

Gabumon was moaning loudly, his tongue hanging out as the pleasure raced through him. He’d gone too long without getting some action, and now that he had an eager Impmon bouncing on his dick, it was all he could do to hold himself back from cumming. He’d been hoping for a bit of a jerk session with Guilmon, maybe a blowjob if he was lucky. But now he had a hot, eager ass riding him like Impmon’s life depended on it. He started thrusting his hips up harder, his knot starting to stretch Impmon’s rear.

There was no way he was going to let himself cum until his knot was buried inside the other digimon. He pulled Impmon down, bouncing the other male harder and harder on his knot until finally Impmon’s pucker gave way, and Gabumon howled out his pleasure as that hot little ass surrounded his knot. The moment the knot was inside him, Impmon came, hard. His cum spurted over Gabumon’s belly and chest; a few shots even hit the bottom of his chin. But more importantly, his orgasm had his ass spasming and milking Gabumon’s dick, enough to feel the other male’s yellow balls jump against his rump as the warmth of Gabumon’s cum filled his insides.

Impmon let his legs go limp, gravity pushing that big digidick a bit deeper inside him while he basked in the afterglow. Fuck, he’d needed that even more than he realized. From the look of the male under him, Gabumon had too; the lucky guy was splayed out on the ground, moaning and panting gently, a squeak escaping his throat whenever Impmon moved and pulled on his cock. Impmon’s orgasm had been hard enough to leave his legs weak and tingling, and normally he would have happily sat there until Gabumon’s knot went down, assuming he didn’t just start riding him again immediately. But his wasn’t the only cock in the cave, and Impmon was eager to see what the red dino watching him and steadily dripping pre onto the ground could do with that dick of his.

The pressure on his prostate - and his eagerness for another big dick to play with - kept Impmon hard while he waited for Gabumon’s knot to go just enough for him to push himself off. Gabumon whined and yelped at the pull on his dick before laying back, shaking from the stimulation. Impmon could feel the warm cum running down his legs, but he didn’t care. In fact, it would make perfect lube for what he had planned next.

“Get over here, pineapple head,” said Impmon, turning away from Guilmon and getting down on all fours. “We’re gonna have some fun.”

Guilmon tilted his head curiously, but got to his feet, his big dick bouncing hypnotically as he moved. Fuck, Impmon couldn’t wait to feel those ridges pounding his ass.

“Fun?”

“Yeah. You wanna have fun, right?”

Guilmon nodded eagerly. He looked down at his cock.

“But can we have fun like this?” His cock flexed, dripping onto the floor again.

Impmon groaned under his breath. The red dino wasn’t the brightest, but even he had to know what he was doing. Or maybe he really was just that dense that he didn’t realize Impmon wanted to get fucked. But Guilmon had a big dick and strong legs, and Impmon could work with that.

“Fucking yeah we can,” said Impmon, reaching back to grab Guilmon’s dick and pull him forward. Guilmon moaned at the feeling of another digimon touching him there, following obediently as Impmon guided him down onto his knees and into position under his tail.

Letting go of Guilmon’s penis - though not without giving it a parting squeeze first - Impmon lowered himself and extended both arms back towards Guilmon.

“Alright dummy, listen up and do what I say,” said Impmon. “First take hold of my arms.” He waited for Guilmon to do as he was told. “Then when I tell you, push your hips forward so your cock goes inside me.”

“Cock?” asked Guilmon.

“Are you fucking kidding me!?” exclaimed Impmon. “Your cock, dumbass! That big piece of meat between your legs! Your going to put it inside me and –”

“Like this?”

Impmon cried out as Guilmon thrust forward, hilting himself under the other digimon’s tail without warning, or even giving Impmon a chance to finish explaining. If it weren’t for all the cum inside him such a quick entry might have been uncomfortable, but after the stretching he’d gotten from Gabumon Impmon was seeing stars. Fuck! That dick hit his prostate like a spear, stretching the small digimon so much deeper than he’d been before.

And he wasn’t the only one moaning. He could feel Guilmon shaking from the unexpected pleasure of having his dick inside someone else. He even pulled on Impmon’s arms like reins, jerking the other male a little further onto his dick without even being told to.

“Impmon feels so good…” moaned Guilmon. Though when Impmon didn’t answer, too lost in his own feelings to do so, the red dino got worried. “Did Guilmon hurt Impmon? Guilmon sorry, I stop now…”

But as Guilmon pulled back, the ridges along his cock caught on Impmon’s tailhole, stretching the digimon out and making him tighten down even more in enjoyment, while also sending bolts of pleasure racing up Guilmon’s spine. Simple as he was, any thoughts of stopping immediately vanished once that pleasure hit. Instead, he tightened his grip on Impmon’s arms and thrust back in, pulling him back to meet those strong red hips. Impmon was practically wailing as his chest was pulled into the air, forced up by Guilmon’s strength and the power of his thrusts as the dino digimon started humping away at him.

It was even better than he’d hoped. Impmon’s moans were loud and constant, save for when Guilmon humped him especially hard, their size difference pushing the air from his lungs as that cock stuffed him good. And the ridges! Holy fuck, if he’d know Guilmon had them and how good they would feel he’d have jumped the idiots bones months ago. He would definitely be coming back for repeat performances after this. But for now, Impmon just let himself go, giving into the pleasure and the powerful thrusts of the lusty digimon above him.

Guilmon’s inexperience showed in his endurance. He might have been able to keep humping Impmon into unconsciousness, but the dino digimon just didn’t have the experience needed to keep himself from cumming. It didn’t take long before he slammed his hips home, locking himself to Impmon as his knot swelled and an even bigger load of hot spunk flooded the squirming male’s backside.

Not that Impmon was complaining. Sure, he would have liked to keep going, but the full, deep stretching he was getting combined with the tidal wave of hot jizz pulsing against his prostate sent him screaming into another powerful orgasm. Guilmon was still trying to hump Impmon despite the tie, and that meant that Impmon’s cock was swinging wildly as he came, painting the cave floor and his own stomach in equal measure every time Guilmon’s hips slapped against his ass and made Impmon’s cock slap against his belly.

The pair both gasped when Guilmon accidentally pulled back too hard and his knot came free, his still cumming cock making a mess of both of them as he fell back on his rump and rode the waves of orgasm right into a blissful afterglow. Impmon was left gasping in a puddle of cum on the ground, trying to catch his breath, his cock jumping twice more before his orgasm was spent. He rolled over onto his back, not giving a shit that he was getting even more covered in cum as he did so. He could also have Guilmon lick him clean later; that would be fun.

A noise from the mouth of the cave got Impmon’s attention. Lifting his head slowly, his eyes turned towards the sound and a smirk spread across his face at what he saw. Standing at the mouth of the cave, trying and failing to hide himself, was a veemon. A clearly male veemon that had one had wrapped around his bright pink cock and the other over his mouth failing to keep him from being heard. Clearly he’d been jerking himself off, no doubt attracted by Impmon’s cries of bliss while he was getting fucked.

Impmon perked up considerably when he got a better look at the veemon’s penis. While comparable in size to his own - though Impmon took satisfaction in seeing that his own cock was still bigger - he sported ridges similar to Guilmon’s (although lower and more rounded) and more importantly a nice knot beginning to swell at the base.

And that was all Impmon needed to see.

In a flash, he was on his feet and moving towards Veemon, who was still too busy fumbling to get away before Impmon grabbed him and drug him into the cave. Throwing Veemon down on his back, Impmon straddled him and pinned the blue dragon’s arms beside his head, grinning down at him wickedly as he pressed his cum-smeared ass back against the other rookie’s prick.

“Must have liked what you saw if it got you this hard,” teased Impmon. Veemon whimpered as his dick slid between Impmon’s cheeks, his face burning pink as he blushed. “It’d be a shame to let a good dick go to waste, and I’ve still got plenty left in me. So…”

Impmon sat down, impaling himself to the root on Veemon’s cock in one go before immediately starting to bounce up and down, keeping the wriggling, moaning male pinned as Impmon had his way with him.

“Be a good boy and let me have my fun,” said Impmon, tightening himself and grinning as Veemon’s moaning grew louder, echoing through the cave. “And you better get comfortable, too. I’ll be keeping all three of you boys busy until I’m spent. Unff! And it won’t be anytime fucking soon.”
