The surgeon-mage who had altered Petrifact's body had warned him to give the new addition a few days before… testing it. Petrifact had not argued with them.
He could feel it himself - the way his body reacted to the new opening like a wound, the indomitable stone cut away and a foreign softness left in its wake. It had been excruciating lying there on the table, flexing the strange new twitch of movement he needed in order to slide a stone cover over the orifice, and then slide it back open. Open and closed, open and closed, all while the surgeon-mage dispassionately watched.
The bargain had been struck thoroughly and fairly, if crassly. Hailstorm had paid money to the surgeon-mage, and in exchange the surgeon-mage had made Petrifact - vulnerable. Given him a way to take his husband inside of himself, to fulfill a role he struggled with. His husband's desire was interesting, in its way. Flattering. Even attractive. But it was something Petrifact appreciated with his mind, not his body. Stone did not lust like flesh did, and he had not been made with this purpose in mind. Thus the surgeon-mage, to alter his purpose.
He would have done it himself if he could. Would have preferred this to be a secret only his husband held on his tongue, for this to be something he gifted to Hailstorm by his own skill. But Petrifact was not a craftsman and had no experience with sex, and his husband deserved the best.
And so Petrifact moved about the house with a vulnerable secret cored into his stone and waited for it to feel more like it belonged to him.
It was the morning of the third day after the change, and Petrifact went about his ordinary tasks even as his mind wandered. As his attention focused itself on one specific part of his body.
Last night, Hailstorm had asked him to remove the cover over his new genitalia. Had looked at the soft folds of the addition and had jerked himself off to the sight, had come onto and around it in messy splatters. Had told Petrifact what he would do to him once he was ready. How much he wanted to fuck him, to find out what it felt like, to make Petrifact orgasm around his cock -
A sensation of wetness interrupted the thought. Petrifact stopped halfway through washing a dish to stare down at himself in surprise. There was fluid trapped behind the stone cover. He could feel it. It was accompanied by a strange, restless sensation of urgency. Need.
Slowly, he returned to washing the dishes, monitoring his body's reactions. His mind began to wander again.
What would it feel like for his husband's cock to be inside him? He knew the shape of Hailstorm's cock well - had taken it carefully into his mouth, felt how strong and hard and large it was, how perversely soft and sensitive and fragile it was at the same time. He knew that he had been altered in such a way that he would perfectly accommodate his husband's cock. That it would be pleasurable for Petrifact to have it moving inside him. That he would wrap snugly around the penetrating object, but stretch enough to allow it to swell inside him.
Petrifact's body shuddered and produced more slick. Readying itself for his husband. And he was ready, he thought, with a sudden urgency. He wanted something inside of him. Something to touch and rub the sensitive flesh under the stone cover. When was Hailstorm coming home?
Not for another hour or two yet, Petrifact saw, and tried to calm himself.
Hailstorm had told him they would do a lot of preparation before Petrifact's first time. Claws and tongue to gently ease him open, acclimate him to touch and penetration before introducing him to something as large and as stimulating as his cock.
Perhaps Petrifact could be… proactive. Get the first touches over with, his body adjusted to the stimulation. Ready himself so that when Hailstorm got home, he could sheathe himself inside of Petrifact without delay.
Petrifact gripped the edges of the counter, his body struggling with urges he could not quite decipher. That it wasn't his role to decipher. This portion of Petrifact's body did not belong to himself. The missing stone was a gift he had given to his husband, and the payment he would receive in return was Hailstorm filling the empty space, completing him. It was Hailstorm who would know what to do with the troublesome organ. All Petrifact needed to do was surrender himself, let himself be made whole. And that meant he needed to wear the collar.
His course of action determined, Petrifact went and fetched the wide leather collar Hailstorm had purchased for him, latched it around his neck. His breath came out hard and shuddering as he did. Willingly forfeiting his own power, his own ability. When he wore the collar, he obeyed. That was the bargain. He wondered, sometimes, if Hailstorm knew how total his obedience could be.
Petrifact knew the bounds would never be tested. That was why he had agreed to wear it.
Petrifact retired to the living room, curling up on the floor to inspect the stone cover over his vent. There was a barely perceptible seam all the way around it, betraying his secret to anyone who knew to look. Slowly, he retracted the cover.
Fluid seeped out from the opening as soon as it had an outlet, clear and slick. The folds surrounding the opening were flushed and plump, the clitoris above it prominent and darkly colored.
Tentatively, Petrifact curled in on himself further, hot with embarrassment. He flicked out his tongue, darting a taste of the fluid. It tasted like - nothing, really. Minerals, perhaps. Not much like his husband's cum.
Not yet, Petrifact thought, and shivered at the thought. At imagining the way Hailstorm's cum would be deposited inside of him. Tidily stored away in the place that had been designed to receive it.
His clit twitched, begging to be touched, and Petrifact licked it, a quick flick of a stone tongue across its delicate, trembling head.
The sensation forced an undignified sound out of him, pleasure jolting up his body. It felt so visceral. So fleshy and sensitive, registering pressure and texture with fine detail and transmuting that information into something indescribable. Stone couldn't feel like this, couldn't yield like this.
He licked it again, quaking, and very soon had his face buried in his own vent, his tongue dragging over it, cleaning up the fluids. When he pressed his tongue into the opening it was an even stranger feeling - an intrusion into a body that was not made to be intruded upon. His mind scrambled to make sense of the feedback it was getting, of depth and inside and the width of his tongue.
Petrifact mapped the inner contours of his vent with his tongue, dragging it over the complex texture of ridges and bumps which would stimulate Hailstorm's cock when he was fucking him. He groaned and whimpered as this prompted more fluid out of him, glad he was home alone, that he was able to take this step in some privacy.
He stopped being glad about it rapidly. His tongue felt good, but it wasn't enough - wasn't thick enough or deep enough or textured enough. It was Hailstorm he wanted, he needed.
Was this how all flesh dragons felt? Was this just what it was like to have a vent? It was a mildly horrifying thought. How did anything ever get done apart from mating?
Experimentally, he flicked his tongue in and out, mimicking thrusting. His body liked that, quivering as the stone slipped easily through his fluids. It wasn't quite what he needed though. Still too slender and too smooth.
He pressed his claws against the opening, slipping a few inside himself, groaning at the added stretch. Still not enough, not deep enough, but better. Rougher, more stimulating. It prompted more slickness out of his body, more pleasurable sensation.
Petrifact had hoped that touching himself would take the edge off of his urgent desire, but it seemed to do the opposite. It rather increased the urgency, in fact, made him desperately want - something. A satisfaction, a final destination. An orgasm, perhaps. Was that the purpose of an orgasm? To dampen the fire?
He attempted to coax himself towards that end with no real knowledge of how to do so. It was difficult to manage. New sensations startled him, and intensity distracted him, made his motions uncoordinated. The elusive precipice slipped maddeningly away from him every time he thought he might catch it unawares. He hissed and cursed to himself each time it did, desperation increasing.
Keys jingled in the door, and Petrifact sat bolt upright, sheer mortification heating his body. Hailstorm stepped into the room, his voice warm and amiable.
"Petrifact, I'm home! Hey, what-"
His words stalled as he caught sight of Petrifact, his mouth opening in wordless shock.
Petrifact felt the look acutely, could feel every inch of what a debauched sight he was. The uncoordinated pile of his body, the slick fluids coating his belly and his claws and his snout. The collar around his neck. The flushed wet folds still visible- Petrifact snapped the stone cover closed over it, twisted his body and his face away.
"You got home early," Petrifact said, as levelly as he could.
"I mean. Not really," Hailstorm said, and put his keys on the key rack without looking away from Petrifact. "Really nice welcome though. Is there something you want me to see?"
Petrifact shuddered in embarrassment and arousal. He was still so heated, so sensitive. He felt excruciatingly vulnerable under Hailstorm's stare. But he was wearing the collar, and so he turned his body towards Hailstorm again, opened the cover.
"You were jerking off?" Hailstorm asked. His voice was teasing, but there was an intense edge to it. He felt very large in the room as he loomed over Petrifact, very close. "Without me?"
"I felt a… need," Petrifact forced out. "I couldn't - I did not resist it."
"Well? Did it feel good?" Hailstorm asked. His eyes were fixed on Petrifact's opening. The slick folds surrounding it, the trickle of wetness leaking out of it.
"Yes," Petrifact said, rough and choked. "But I wanted - I couldn't - it wasn't enough." It felt like a confession. Indirectly begging for what he had too much pride to actually beg for.
"Couldn't figure out how to come?" Hailstorm asked, with a cloying sympathy.
Petrifact mutely shook his head, his body heating further at the tone. Hailstorm establishing he was in charge, that he knew what he was doing. That Petrifact had betrayed a lack of knowledge that Hailstorm found amusing.
"Aww, that's cute. Don't worry, I can tell you tried really hard. Let me help."
Hailstorm's claws were on Petrifact then, and Petrifact went pliant under them, going where he was put. On his back, mostly, his lower body looped in such a way that the segment of Petrifact's body that housed the new orifice was draped on top of the coils, raised and presented. He waited for Hailstorm to sheathe his cock inside of him, his body tensed and ready for it.
Instead, Hailstorm lowered his head and dragged his tongue across the opening, swiping up Petrifact's slick, licking him clean.
Petrifact moaned in surprise. It felt so good - the unexpected nature of it, the sheer heat and wetness of Hailstorm's clever mouth. How it moved in a way that Petrifact had not chosen, unpredictable. But it wasn't what he wanted. Not what the hole was for.
"You need not - I already prepared myself," he said, his voice rough and trembling under the onslaught.
Hailstorm lifted his face for a moment. "You tried," he said, gently condescending. "But you don't know how to do it right. So I'm going to show you."
"Oh," Petrifact said, his voice treacherously weak, and submitted.
It rapidly became clear that Hailstorm was correct - Petrifact's clumsy lapping at his own slit had been a fumbling first attempt, pleasurable more by accident than by any purpose. Hailstorm's mouth and tongue moved over him with skill and intent, tracing between his folds, delving inside of him, rolling Petrifact's clitoris between lips and tongue in a way which made Petrifact whimper. It was almost overwhelming, too pleasurable and too intense.
"Please," Petrifact begged, not quite knowing what he was asking for. To be satisfied, above all. To have his urgent desire sated, to be filled.
Hailstorm focused his tongue in hard circles on Petrifact's clitoris and slipped claws inside of him, crooking them and stroking against Petrifact's inner walls in a steady rhythm. He kept it up, quick and firm and relentless, until Petrifact was shaking under it, his body lighting up, drawing tight -
He cried out as the tension released in a burst, his body squeezing and shuddering, his slit throbbing with relief as he came. It was indescribable, a bright shock of lightning up his body, a shivering release, his mind wiped clean. Slick wetness rushed between his thighs.
A split second of terror struck him as he came back to himself - the way his body was clamping down uncontrollably around Hailstorm's claws, had he hurt him, had he crushed him? But no, the claws inside him kept working away, unhampered. The soft insides of Petrifact's body were too weak to crush anything, could only flutter and grasp and cling. Petrifact moaned at the realization, how helpless he was, how vulnerable to penetration.
Hailstorm's tongue and claws slowed as Petrifact's body slowly relaxed itself, coming back to normal.
"See, that's how you do it," Hailstorm said, lifting his head with a smug little grin. "Now you know for next time."
"I see," Petrifact said, in a rasp.
Hailstorm chuckled and licked over Petrifact's clitoris one more time, making him jump, oversensitive. "I love how sensitive you are now," he told him. "You're just desperate for it, aren't you? It's like you're in heat. A couple decades going without sex catching up to you all at once, I guess."
Petrifact felt shivery, cracked-open. He understood the term heat. Had read the description in a book, speaking about a female animal's mating season, of the desperation to be bred. Perhaps it felt like this. Perhaps those animals also felt that driving urge to receive, to be taken, to be filled. It was a good thing that Petrifact couldn't bear young, because he did not know that he could have resisted the temptation to let Hailstorm give him some.
Hailstorm grinned at whatever he saw on Petrifact's face and kissed his belly, just above the wet mess of his opening. "Don't worry. I'll give you what you need."
Petrifact watched Hailstorm stand, watched him undress. When his pants came off, Petrifact could see Hailstorm's cloaca was half-open, the tip of his cock peeking out.
"Do you need a break?" Hailstorm asked. He rubbed his claws around his cloaca, then stroked his cock as it slid out into the open. Petrifact watched Hailstorm's paw wrapped around the thick, slick shaft, moving over it, and felt sick with desire. His opening twitched with renewed interest, with the desire to be filled. He could feel the hunger pangs deep inside him, an urge which had not yet been met.
"No," Petrifact said, slightly too quickly and too harshly. "I don't need a break," he added, which didn't help the tone. "I just need - I need-" The words caught in his throat, too mortifying to say. He rocked his hips up towards Hailstorm, letting his body speak for him, slick and open and ready.
"Yeah, I know what you need," Hailstorm said, a little huskily, and Petrifact watched his cock harden even further, twitching in his claws. "Alright. Hang on."
Petrifact let Hailstorm move him around again, this time laying him flat on his back, spread out beneath Hailstorm's body. Hailstorm kissed Petrifact as he straddled him, and Petrifact kissed him back, tasting his own fluids. He was intensely aware of Hailstorm's cock rubbing against his lower belly, dragging over his opening, slicked with the fluid Petrifact couldn't stop producing.
Hailstorm pulled back after a minute, looking down between them so he could line the smooth, tapered head of his cock up with Petrifact's opening. Petrifact watched with unwavering attention.
He had never had cause to think of the size of Hailstorm's cock as anything except naturally proportional to Hailstorm's own body. Perfectly suited to its context, a shape and a size he knew intimately. In this context, however, it suddenly seemed enormous. Much larger than a tongue or a few claws. He could see exactly how deep inside him Hailstorm was going to be, how many inches of his body he would cede. It was unfathomable. Impossible.
He knew Hailstorm would get much larger before he was done.
The slender point of Hailstorm's cock caught at Petrifact's opening, and Petrifact drew in a tight breath as he felt the first stretch, as he parted before the intrusion. It went in slick and easy, gliding through Petrifact's wetness, and Petrifact felt every inch of it. Felt the smooth, velvety skin, felt every one of the barely-perceptible bumps running down the sides of it as they entered him.
By the time Hailstorm bottomed out, his hips coming to rest against Petrifact's stone belly, Petrifact felt utterly senseless. It was so deep inside him. The pointed tip of Hailstorm's cock was nestled somewhere in the very core of him, pressed firmly into a particularly sensitive spot that Petrifact had not known the surgeon-mage had given him. The hollowness inside of Petrifact was filled, his body made whole again by the presence of his husband's cock.
Ah, this is what I'm for, Petrifact thought, stupidly, nonsensically. It was just the hole speaking, he knew, the shuddering satisfaction that was resonating through his body. But it spoke… loudly. Drowned out every other sensible thought except the one which told him to bite his tongue, to not speak it out loud. This is the point of me. To be a sheath for his cock.
"How's it feel?" Hailstorm asked, rough and breathless.
Petrifact struggled for words, what to say without being obscene.
"Full," he managed.
"Is that good?" Hailstorm checked.
"Good," Petrifact confirmed, and Hailstorm huffed out a breath of laughter.
"It gets better," he promised, and proved it by pulling partway out of Petrifact, thrusting in again.
Hailstorm thrust slowly at first, shallowly, his cock sliding in and out of Petrifact in a lazy rhythm, introducing Petrifact to a range of pleasurable sensations he had not been aware existed. Petrifact closed his eyes to concentrate on them more wholly. Motion and friction across sensitive inner flesh, the stimulating pressure against his inner walls. And Hailstorm was so warm. Petrifact's stone flesh was always cool to the touch. In contrast, Hailstorm's cock inside him felt like it was radiating heat, like he was warming Petrifact from the inside. Burning him up.
"Yeah?" Hailstorm said, with a breathless laugh. "You like that?"
Petrifact was confused for a moment, and then abruptly realized he was making a sound. Very quiet, almost inaudible. Almost. He could hear it now, a low rumble in his throat, ebbing and rising with the movements of Hailstorm's cock. His mouth had fallen open slightly, his head tilting back, his eyes closed. Transparently, obviously enjoying himself.
"How about this?" Hailstorm asked. He drew almost all the way out, then thrust back inside, quick and hard, burying himself to the base in one smooth motion.
Jarring pleasure went up Petrifact's body, and he moaned, his claws digging into the floor as Hailstorm repeated himself, fucking into Petrifact's body with a purposeful rhythm. A steady, pounding pace that never quite gave Petrifact the chance to recover between thrusts. Petrifact could do nothing except feel, except receive.
He felt every minute change as Hailstorm's cock flared inside him, growing from something smooth and slender which slipped easily in and out of Petrifact. It got thicker first, stretching Petrifact wider, increasing the pressure inside of him. Then the bumps lining the sides flared into blunt spines, scraping and dragging at Petrifact's inner walls, rubbing hard into matching sensitive points lining Petrifact's insides.
If Petrifact had thought himself overwhelmed before, now he knew what it truly meant to be overwhelmed. His vent was stretched as far as it could stretch, wrapped so, so tight around his husband's cock. A perfect sheath, a vessel filled to the brim and no further. His passage clung so closely to the thick shaft inside of him that he could feel every contour of its shape, of the spines lining it. Every motion felt like a shock, every thrust thudding into him and lighting him up.
The thrusting slowed. Petrifact whined in instinctive protest as Hailstorm pulled most of the way out, rocking shallowly.
"Give me a second, I'm going to come if I'm not careful," Hailstorm said, panting.
"And?" Petrifact managed, trembling with the effort of remaining still, of not trying to work himself farther onto the cock teasing at his opening.
"What, you want me to come inside you? Make a huge mess?" Hailstorm teased, with a breathless laugh.
Petrifact said nothing, just squirmed.
Hailstorm said, "Oh, you do," with growing delight. "You really want it. Okay. Yeah. Beg me for it."
"Hailstorm," Petrifact said, mortified.
"You want this?" Hailstorm said, and gave Petrifact a couple of good, deep thrusts that made him moan. He pulled back out, rubbing the tapered head of his cock against the opening. "Then beg me to come inside you. Come on, baby, you can do it."
Petrifact shook with need. "Please," he forced out.
"Please what?"
"Please - come inside me," Petrifact said.
Hailstorm's face was still expectant. Petrifact scrambled to find the right words to convince him, plunged on, vulnerable and shaky and obedient. He couldn't get any more embarrassed than he already was. "I want you to fill me up with cum. Please. It's what I'm - it's what it's for. Is for you to come inside."
"Yeah," Hailstorm said, with a groan, and drove his cock back inside Petrifact again with a wild edge. "Yeah, it is, isn't it? This is all for me."
He leaned the entire weight of his body down on Petrifact, and Petrifact felt Hailstorm's teeth on his neck, his hot breath. He seized the collar between his teeth as he fucked deep into Petrifact, quick and hard and greedy. Petrifact trembled under the onslaught. He was wound so tight, his mind going blank. There was nothing in the world anymore except the feeling of being fucked.
Hailstorm thrust in a few more times, deep and hard and ferocious, and then came with a loud groan, his cock pulsing inside of Petrifact. Petrifact felt him come, felt the burning heat of cum flood him. The moment of stillness, the extra little bit of stimulation - Petrifact's overwhelmed body seemed to suddenly remember how to orgasm. He cried out, his body coming around his husband's cock, fluttering weakly around it.
They lay together in the aftermath, Hailstorm's cock still buried to the root, Petrifact floating in a haze. He loved Hailstorm so much. He'd been so good. It felt so good. If Hailstorm stopped touching him he was going to die.
Discomfort crept in eventually, Petrifact's opening beginning to protest at the overstimulation. He opened his mouth to ask Hailstorm to pull out, but it came out as a plaintive little whimper.
"Awww, baby," Hailstorm said, and propped himself up with an effort, pulling slowly out of Petrifact. His cock had softened, returning to something smooth and slender as it disappeared up inside his cloaca.
Petrifact lifted his head enough to watch as Hailstorm's cum seeped out of his opening. Hailstorm caught him looking, looked down too.
"That's so hot," he said, fervently. Then, "You're so hot. You're gorgeous. I'm so lucky to have you, you're just perfect. You were so good for me today."
Petrifact clutched at him, trying to do so carefully. Delicate holds, not crushing. He overcompensated a little, found himself pawing weakly at Hailstorm's body. Hailstorm curled around him, kissing his face and his neck, saying a variety of other sweet things.
Petrifact felt very slow and dizzy and fragile. Something about the fucking had unmoored him from the core bedrock of his own self, gotten him lost in the hedonism and fragility of flesh. Hailstorm's touch - his kiss, his comforting weight - helped. Made him start to feel real again. Maybe he'd wrung the worst of his desire out of his system, could function again.
Later, when Hailstorm had finished cleaning Petrifact up and they'd had dinner and a chance at a normal conversation, when they were getting ready for bed, Hailstorm smiled at Petrifact in a certain way, heated in the way that meant he was thinking about sex - thinking about Petrifact.
Petrifact felt an answering throb from his slit, stood very still as he processed the look. The renewed desire of his own. He still felt a little tender from the first round, but that wasn't necessarily going to stop him.
When he climbed into bed with Hailstorm, he let the stone cover over his vent slide up a little, show off. Discreetly indicate that it was…. available for use.
"What, you want it again?" Hailstorm asked, with amused delight. "Already?"
They fucked again that night, and again the following morning, and then Hailstorm put a stop to things so he could go into the other room and call Einar and let him know that he needed a week off work or so. Family emergency, he said. Serious illness, needs cared for.
Petrifact, who was only experiencing illness in the most colloquial senses, felt a thrill of petty satisfaction. He disliked Einar for no good reason. Merely that Einar had the power to tell Hailstorm where to go and what to do, and that he shared a world with Hailstorm which Petrifact would never be able to truly enter. It was obscurely pleasing to hear Hailstorm going through the motions of choosing Petrifact. Taking time to put Petrifact at the center of his priorities, to repay him for the gift Petrifact had given him by accepting the alteration to his body.
He resolved to be very good for Hailstorm this week to show his appreciation.
