"Do you *really* think it's okay to use one of Nergigante's horns as a dildo?"

Jamus hefted the horn. "It's too splintered to use as a weapon. But you grind it down a little, brace the rim..." Jamus mimed the motions, hands spanning across the bulky horn, and Zan looked on, a faint blush staining his cheeks as Jamus stroked the immense horn. "It'll be fine." He leered. "It's not too big, either." The horn was nearly as big around as his thigh. Zan flushed deeper.
Jamus left the finished dildo on their bed, ludicrously huge and heavy enough to leave an imprint in the mattress. He was off working until the evening, and he'd left it there for Zan to find when he entered their cabin, half intimidatation and half surprise.

Well, if it was there for him to find... Zan found himself thinking, stripping off as he got their urn of lube out. If it was there for him to find, Jamus was gonna come home to him hilting the thing, he thought as he stripped off his clothes, padding naked to the bed.

"Oh fuck," Zan groaned softly, rutting back against the head of the dildo. Maybe Jamus was more adventurous than him, but this thing was *way* bigger than anything he'd taken before, including Jamus fist all the way to the elbow. Still, there was something about its sheer size that sent sparks of heat racing up his spine as he nosed the smooth, blunt tip of the dildo against his spread asshole. It was heavy enough to fix in place and then just rut back against it, and so he found himself on all fours, dildo mounted on the wall, shaking rutting backwards, feeling his slick, lubed-up asshole slowly yawn wider and wider as he worked himself open. The smooth, bulbous tip sunk inside him with a soft squelch, the rigid bone instantly mashing down hard against his prostate, and Zan let out a surprised bellow, muscles going slack as he slowly rode down, impaling himself on the toy. The smooth bone bore down into him, hard and implacable, and Zan let out a shaky moan, stomach clenching and relaxing, as he opened himself up. His cock was leaking, a glimmering string of pre hanging from his half-hard cock, sluggishly lengthening each time his cock twitched.

He rode the dildo, knocking it against his prostate, milking out a wet spurt of pre as he ground down. The bone wasn't quite as smooth as it seemed at first -- there was a drag as he rutted back against the head, a rough rasp scraping over his skin and sending a hot frission all across his ass and thighs. Zan groaned, rutting back further, exhaling with a shaky gasp as he sunk the entire head into his ass. It was enormous, stretching him to the utmost, and he shakily rode the tip, letting the smooth lip of the cockhead slurp back and forth over his aching asshole. The drag of the tip got more intense, raking across his guts as he sunk deeper, and the hot sandpapery drag spilled down the shaft until it felt like it was concentrating at the rim of the carved cockhead. Short, rubbery spurs dragged across his asshole as he fucked himself, and it wasn't until he tried sinking even deeper and then pulling off that he realized what was happening: Nergigante's bone was regrowing, forming fresh new spines all along the surface of the dildo.

Maybe making the dildo out of Nergigante's horn was a bad idea.

The spiny shaft rasped inside him, still-forming barbs soft and rubbery as they raking across his internal walls. The pulsing inside him got stronger, asshole convulsing around the toy, smooth muscle clenching around its growing bulk. Zan's internal muscles pulsed, and his still-soft cock twitched hard, and he was abruptly gushing streamers of cum onto the mat below. He lurched forward, springy barbs rasping across the rim of his asshole, and the dildo pulled out of him with a wet *slurp*, leaving him panting on the floor, face on the ground, splayed asshole still kissing the spiny cocktip.

He lurched to one side, cock draping across his thigh, and felt back against his hole: swollen and heavy, the lip of his asshole bruised and sore from the barbs, and then with two fingers shoved deeper inside he twisted his thumb across his him, forcing out another spurt of cum. The skin around his ass felt scaly, not torn exactly, but roughened by the use, and it was only dimly as he flopped to the side to get a better look at the damage that he realized his cock was a lot weightier than he was used to.

Looking down: his cock was as big as he was hard, but still totally soft, spilling down his thigh. He tugged on it, aware of a strange drag inside his foreskin, and still hazy after cumming he pulled his foreskin back -- more of it than he was expecting -- and tried to get a better look. Slowly jerking off with two fingers in his ass, he started to get hard. His cock fattened even further in his hand, cockhead pushing free of his loose foreskin, and -- that was definitely not his cock. The head was tinged a strange blue-purple, tip pointed and growing more pointed even as he stared down at it. Fat, springy barbs bulged out across the rim of his cockhead, hot pinprick sensations along the length of his shaft as more grew in. He let out a shaky moan, cock leaking again, a milky blue-white fluid, and that got him to feel further down over his balls: skin there growing scaly, leathery even, as he ran his fingers over the flesh of his sac. His balls ached, hot pressure growing inside them, and dimly he realized his prostate was throbbing, pulsing inside him like a heart, squeezing and clenching like a living thing as it swelled and grew fat and dense inside him. Internal muscles lurched hard, foreskin nearly all the way shifted into a fat, puffy sheath framing his halfway-unsheathed cock, and his cock spat out a thick, stringy rope of altered pre, blue-white and luminous.

Zan groaned, dimly aware of the transformed dildo behind him, pressing against his thighs. It was almost unrecognizable, the carved cockhead ringed with a spray of translucent white barbs, each nearly as fat as a finger, with the same spiralling pattern of barbs ringing down the shaft as he now had growing on his own. Desperate, needy, he lurched back, impaling himself again on the still-growing cock, letting out a deep guttural roar as the barbs dug into the soft flesh of his guts. His cock thickened, still hardening and also still growing huger and longer, sheath becoming mottled with patchy purplish hide. His balls ached, dragging down lower and lower until they touched the ground, hanging to his knees, easily fist-sized each, as he fucked himself on the dragon-bone dildo.

"What the hell is going on?!" he heard Jamus cry, and he looked up to see him in the entryway of the cabin, looking down at him, shocked. Zan just moaned, pulling free from the dildo again -- harder now, with the thick spurs starting to harden into spikes -- and lurching forward on all fours, aware his nails were starting to grow into thick talons.

Now with another person there -- with *Jamus* there, who he'd planned on fucking the moment he showed up anyway -- there was another drive making itself clear. His cock hung between his haunches, huge and barbed, spines fluttering weakly up and down his shaft. His balls dragged between his thighs as he crawled forward, panting and rasping. He had to fuck. He had to *breed*. He pounced, bowling Jamus backwards and pinning him down, rutting the full length of his cock between them -- the sharp, spiny tip pressed aganst his pecs, drenching them both in his gleaming pre. "Gotta fuck you," he growled, voice deepening. "Gotta *breed*!" He kissed Jamus hungrily, moaning into his mouth as he rutted against him like an animal, desperate needy sounds ripping their way from his throat.

"Oh fuck," Jamus groaned, his trapped cock grinding up against Zan's balls. It was a little unfortunate that he clawed right through Jamus's clothes when he flipped him over, bodily tearing them all apart, but, well, Jamus was the crafter; he could make a new outfit. Zan ground his cock across Jamus's back, clawed hands digging into the muscle of Jamus's ass, spreading him open so he could grind his pillowy sheath right up against his hole. His cock gushed pre between Jamus's shoulderblades, spilling down his sides. He drew back -- perched over Jamus on all fours, dimly aware that he was balancing on his forepaws, using his tail as a counterweight -- and sunk the head of his cock into Jamus's ass.

Jamus definitely wasn't lying about the dildo not being too big. Zan's cock, nearly just as big now, sunk into his ass easy, splitting him open wide. His cock lurched, lubing him up with a mass of pre, and he sunk deeper, cock already bulging out against Jamus's stomach only halfway inside him. Zan crooned over him, huffing and panting, and pulled back -- all his spines immediately dug into the flesh of Jamus's guts, rasping and tugging on his insides, and Zan let out a feral animal yowl, cock immediately spraying another immense gush of pre, and Jamus just groaned, body convulsing around Zan immense cock, clamping down harder as the spines sawed back and forth inside him.

Zan wasn't going to last long. Even the slightest tug backwards lit his cock up, nerves firing all down his freshly-transformed length, each stroke nearly bringing him off. He pulled Jamus up, flush against his underbelly, claws digging into his hips -- and one reaching under him, playing with Jamus's thickening cock, rubbing his scaly palm against his slick cockhead. Jamus whined, squirming under him, and Zan jerked forward again, sinking most of his bloated purple cock into his wrecked ass. He came with a bellow, abrupt and easy, cock thundering inside Jamus strong enough to lurch his body to the side, puppetting him on the length of his cock. His balls lurched, prostate throbbing, and dizzily he felt something lurch inside him: thick cum pumping into Jamus's guts, but more than that something heavy and rubbery squeezing up his cock, heavy jellylike spheres pumping into him with each squirt, gurgling as they churned around in the thick swill Zan was pumping him full of. Some new instinct told him what it was: his clutch, a mass of eggs pumped into him, to brood inside him. The thought of it just made him cum harder, pumping egg after egg into Jamus bloated belly, filling him more and more, until with a dimly-felt pressure he could feel Jamus's gut press against the floor, flattening and spreading as he kept him tightly-plugged, more cum and more eggs bloating him fatter and fatter.

Zan groaned, hungrily kissing Jamus's shoulder as his cock pumped more eggs into Jamus's guts. "I think making a dildo out of Nergigante's horn was a great idea," he rumbled, dragging Jamus down his cock until he was fully seated, sheath kissing his wrecked asshole, and Jamus's answering sob as he came all over himself was the only agreement Zan needed.
