Vin stumbled to a halt at the edge of the roof, feet slipping in the wet ash sludge. Crouched on unsteady footing, she shivered against the cold. She was – as had become standard for her nightly patrols – entirely naked, but for her mistcloak and the glass bulb within her butt. Neither did much to shield her from rain or wind.

Burning pewter, as she was, lessened the effects of temperature, but she also used tin, all but negating the other metal. It was an unfortunate set of circumstances that had put her in this situation.

For starters, rain was a rare sight, and this was an unusually heavy downpour. Even so, she would normally have extinguished her tin, but it would leave her as good as blind in the dark night. And tonight she was in greater need of sight and hearing than usual..

For the first time in over a month, Vin had spotted a spy. And better yet, he wasn't alone. As she made her loop around the city, she had come across four people, sneaking across the rooftops.

Only one seemed to burn metals, and he was only a misting. A coinshot, pushing himself ahead between the roofs with a rope for the others to climb over on.

Vin struggled to keep a foothold on the slippery shingles as she tried to keep out of sight of her targets. She was forced to lie against the slanted roof, back to the wet tiles. The rain poured down across her bare chest, her body stiff and shaking with the cold. Vin gritted her teeth, steeling herself against the chill.

When the spies had made their way to the next roof, Vin rose, jumping to follow them. She always kept one house between them, making sure she wouldn't be seen. With tin she could still hear their voices at such a distans. So far most of the chatter had been from one man complaining in a high-pitched voice, and a lower voice telling him to be quiet.

She landed on the next roof, nearly falling face first into it. She climbed onto a dormer in hopes of better ground under her feet. The slope here was less steep, allowing her to squat more securely.

Vin breathed heavily from exertion. She watched as the group of men made their way to the edge of their house, getting ready to cross to the next one. She crawled to the other side of the roof, slipping and sliding on the wet mush of weeks-old ash. As she moved about, Vin could feel the glass plug shift within her rear. A delight, and a distraction.

At this point she had begun chattering her teeth. She shook as she tried to listen in on the group of spies. The coinshot had just leaped to the next roof when a voice Vin hadn't heard yet spoke up.

"This is the one, right?" The voice was hoarse and raspy.

"Should be," the low voice answered. "Just have to find a way in."

"Just smash a window, hop in and open the gate. Ain't so difficult." Vin shifted, stiff body protesting as she tried for a more comfortable position.

"Too risky. There could be guards posted inside."

"Wasn't the passage dug before the Lord Ruler fell. Probably only ska know about it, and they don't have any guards." The man with the raspy voice chuckled to himself.

Now Vin at least knew what they were after. They were looking for a path out of – or perhaps rather into – the city. As the group made their way over to their target house, Vin followed.

Surprisingly, Vin landed on soft ground, her feet sank into the black sludge of soiled ash. It covered her lower legs, painting them black. This roof had clearly not been cleared of ash in a long time, and with the rain, the dry, black flakes had been turned into a thick goo.

Vin waded through the black soup, reaching the other side of the roof where she did her best to crouch. She did not much like the thought of kneeling in the deep muck.

"What's that?" She heard one of the spies say. Vin looked up, meeting the gaze of the four men on the other roof.

She sprung into action immediately. Sprinting to the roof's edge, Vin leapt. With a steel push, she landed at the back of the group next to the smallest of the three infiltrators.

Caught off guard, the man had no chance as Vin – pewter burning – threw herself at him. With a cry the short man stumbled off of the roof, falling to the ground, several stories below.

Vin leapt off again, propelling herself into the air above the three remaining. The counshot fired toward her, the coin spinning in the air as it approached her. Vin pushed on the coin, her force against her enemy's.

She shot off higher, the man below sliding on the slipper roof as Vin's pushed countered his. Vin let go of the coin, letting it shoot off past her. As she fell toward the house, she reached behind herself. With a slight pop and a sharp gasp, Vin pulled the plug from her butt.

She brought it down in front of her as she came down on her enemy, smashing the thick glass ball into the head of the coinshot. The man went down, blood spattering the unharmed plug.

Vin landed hard, but managed to find her footing. The pewter enhanced her balance and kept her standing. Before she could turn around, strong arms caught around the chest. She struggled, but the man held tight.

Must be a pewterarm, Vin thought. No normal man would be able to hold down someone burning pewter. Both burning metals, however, Vin was outmatched by the man's stronger build. The pewterarm gave her a hard squeeze, forcing the air from her lungs. With an involuntary jerk, Vin dropped her plug.

The last man – the only other one still alive – stepped up to her. He was tall and muscled, but had a hunch to his back. He looked down at Vin, expression a mix of horror and vanity.

He pulled out a knife – a glass knife. None of the infiltrators may have been mistborn, but they were prepared to fight one.

"What do we have here," the man with the knife rasped. As he approached, a grin spread across his lips. "The venture boy's little girl running around naked in the night. Is this how he treats his whores, forcing them to run around the town naked?"

"Considering who his father is," the man holding Vin said, "I wouldn't be very surprised." His voice rumbled in his chest, vibrating through Vin's body, as she was pressed to him.

"Now, now," the other man said. "Straff treats his women well. He would not let them out in weather like this. Think about what could happen." He gestured with the glass blade as he spoke, flinging it around.

"Someone might catch the thing." Vin could feel the words almost as well as she could hear them as they thundered forth behind her. "Someone might get their hands on her, and then what might happen? Who knows, eh?"

Vin did not respond. She pushed down her dread, forcing herself to consider her options. Her legs were still free, she would be able to give a good kick to the man with the knife. If only he was a little closer. Then again, that wouldn't do much. She was still held down by someone much stronger than she. No amount of thrashing Vin could muster was likely to change that.

The man with the knife stretched out his hand toward her. Rough fingers touched her slit, parting lips lips. Vin hated how her nipples stiffened. Really, it was a miracle that they could even get any harder, what with the icy weather. Still she could not deny the tingle in her spine.

She steeled herself, looking the man defiantly in the eyes. Just then, she spotted the faint, blue line pointing to the corpse of the coinshot. Vin flared her iron, pulling with all might at whatever the line's source was.

The pewterarm gave a jerk at the sudden tug, and a moment later, a pouch of coins smashed into the man with the knife. The man fell forward, knife held in front of him. In a quick shuffle, the pewterarm avoided the blade, but the same move forced him to loosen his grip on Vin.

In an instant she was free. She jumped back, moving out of range of the misting. She skidded to a halt, ash-mud splashing behind her. The man with the knife lay motionless on the ground, leading Vin to focus on the last man. With a pewter-strengthened jump, Vin pounced on the big man, knocking him to the ground. The slippery surface made it easy despite her inferior size.

She pounded her fist into the man's face. Again and again she hit him. Swatting away his arms when he tried to fight her, Vin did not let up until the man lay still.

Exhausted, Vin's chest heaved with her laboured breath. She was wet and cold, but on her hands was warm blood.

Vin stood naked on her hands and knees as OreSeur pumped his hips into her. She swayed with every thrust, but her large store of pewter – kept on a steady burn – kept her standing. Every time OreSeur pushed his penis into her, her stomach bulged slightly, the semen of countless previous rounds forcing its way out through the tight space between dog and human. When OreSeur pulled out, the pressure lifted, allowing even more semen to flow out, collecting in the large bowl on the floor beneath Vin's crotch.

OreSeur pushed himself all the way in every time, his knot swallowed entirely by his mistress' lower lips, his tip tickling her cervix. Vin had come to enjoy the bone-rattling sensation as her core was prodded. The harsh jolt and tug in her abdomen – a sensation as if her insides were being rearranged – seemed to make her wetter than anything else.

Vin Shivered as a pulse of immense heat filled her once more. She had long since lost count of how many times OreSeur had released within her. They had been going for hours, wave after wave of pleasure blowing through them both as the clay bowl below slowly filled with the thick, white nectar.

Ever since she had let OreSeur into her nethers, they had not gone a night without fornication. Having confirmed that the sperm the kandra-wolfhound produced was entirely wolf-sperm, Vin no longer had any qualms letting her companion fill her as he liked. And OreSeur certainly seemed like to do just that.

The kandra preferred her nethers over the other options, and had been the one to initiate far more often lately. Of course, Vin still made sure her other holes got the attention they deserved, and OreSeur was always happy to oblige. But it was clear that he had his preferences.

With a breathy groan, Vin shuddered through another orgasm. White spots flashed before her eyes as jolts of electricity shot through her body. She curled her toes and fingers, nails biting into her palm. Before the sensation had subsided OreSeur released another load into her depths – overwhelmed by the spasming walls of Vin's vagina.

A splattering cascade of hot liquid dripped down into the bowl. Vin had placed the bowl there for two specific purposes.

The first was that she had grown tired of cleaning her floor. It had gotten ridiculous how often Vin had found herself meticulously scrubbing her room, clearing away any evidence that might point to the private time she was sharing with her wolfhound. Floor, walls, her bed and desk. One time she had even found semen stuck to the door! She was still careful to clean up every night, but having a place for OreSeur to aim had made it far more manageable.

The second reason for the bow was that Vin did not want any of the precious seed to go to waste. With OreSeur now spending most of his time in her vagina, Vin needed another way to make sure she still got her fill of the tasty cream.

This way, she got to make use of it however she pleased.

"After this one…" Vin's words were each one punctuated with a sharp gasp, "I think I'll need a little rest."

OreSeur gave only a wolfish grunt in response, speeding up his rocking thrusts. The sloppy noises of the massive knot parting and clenching of Vin's vulva, the clapping of hips against hips as their bodies rolled into each other, filled the room as Vin came closer and closer to another release.

All at once the two hit their peaks. Vin moaned as her legs trembled, OreSeur howling quietly in her ear, spurt after spurt of heat pouring out into her depths. Before Vin had any time to calm down from her orgasm, the kandra pulled out of her sopping lips, knot stretching her to the max for one final time.

She shuddered as all that had been planted within her was finally allowed to escape. For a few minutes she stood where she was, letting the torrent of semen to trickle out of her, until it finally stopped.

Finally allowed a moment's rest, Vin laid down on the floor, next to the large ceramic bowl.

For a time, they both rested, huddled beside one another on the floor. Their breathing slowed until a calm had settled upon the two, entirely unlike the ferocious activity of just a few moments earlier.

Vin eventually sat up, the wear on her body finally fading. She was still burning pewter, the metal providing her a little extra energy to fight her fatigue. She found OreSeur – as often was the case after their sessions – fast asleep, curled up in a way quite unfitting his size and ferocity.

Vin gave the kandra a light pat, tracing her hand along his furred side. She knew he wasn't really a dog, but sometimes she could not help but treat him like one. Patting him just seemed like the right thing to do.

Vin sat up straighter, turning to the ceramic bowl. It was almost full with the thick, pulpy seed. She stuck a finger into the white solution – still warm – stirring it before bringing the finger to her lips. It tasted pungent: bitter, a little salty.

Delicious.

She stood up, lifting the bowl with her, careful not to spill anything. She opened the door, peeking her head out. Making sure the corridor outside was clear in both directions, Vin stepped out of her room and made her way toward the bathroom.

It was tricky work, sneaking through the corridors with the wide bowl in her arms, its contents rolling dangerously as she moved. Still, years of sneaking about – first as a thief, and now a mistborn – allowed her to move deftly through the hallways. She half jumped, half sprinted down the last corridor to the baths, just barely avoiding being spotted by someone coming around a corner further down the corridor.

Vin swiftly pushed the door shut behind her, locking it with a latch. She stepped down into the large, empty bathtub. Setting down the heavy bowl, Vin sat down in the tub – really it was more like a pool.

As she sat down a trickle of semen spilled from her vagina. She laid back, pulling her legs above her head. With her hands, she pulled her hips closer to her face until she was able to bury her tongue within her own sex.

Vin had not been sure she would be bendy enough, but her flexibility had proven quite impressive. She had a feeling her pewter might have helped her in one way or another.

Aided or not, Vin was more than happy to make use of her plasticity. She licked herself clean, enjoying the mixing flavours of OreSeur's potent semen and her own salty-sweet discharge, as well as the tingling her tongue brought her groyne.

Satisfied with her work, she unfolded herself, turning her attention to the, now cooling, bowl of potent wolfhound's semen. She cupped her hands, lowering them into the thick solution. The semen seeped between her fingers, collecting in her hands, before she brought them to her mouth. Vin lapped up the cream as best she could, getting as much of it as she could before it inevitably fell back into the bowl through the gaps between her fingers and hands.

The self-adhesive texture of the sperm made it difficult to handle. When a title began running down her hands it was as if it pulled the rest with it. In the end more ended up smeared on her cheeks and nose than in her mouth, but what she managed to catch gave her great delight.

She played eagerly with the seed, running her tongue through the small pool in her mouth. She burned tin, her senses filling with the rich, nuanced flavours of her kandra's seed.

When Vin had swallowed, she licked her lips clean, the salty bitterness strong on her tongue.

She quickly disregarded patience, dipping her chin into the bowl. She sucked in as much as her mouth would fit, savouring the taste as she swallowed the thick ejaculate. She flared her tin, wanting to miss a single detail of the experience. Her stomach growled – whether in hunger or protest she neither knew nor cared – as she drank down the pungent seed.

When Vin lifted her head, sperm ran down her chin. It dripped onto her chest and thighs. Just the sensation of it against her skin brought sparks of pleasure through her, and she felt herself near her peak, without an ounce of direct stimulation.

Without hesitation, Vin lifted the bowl over her head, spilling its contents over her body. It rained down over her, coating her hair, then her face, chest, legs. She was washed over with the strangest orgasm of her life. Her body shook, limbs trembling, she struggled to breath as the ecstasy overcame her. It took every bit of self control Vin still possessed not to drop the bowl. Slowly, she lowered it back to the floor, hands unsteady.

For a while, she simply sat in the odd afterglow, covered head to toe in sperm. A puddle was gathering below her, slowly spreading wider and wider as the seed dripped from her skin and hair.

Vin's nipples were hard as pebbles, almost painfully erect. Her vulva ached from the night's many releases as semen trickled down its length. She had to extinguish her tin, the enhanced senses too much to bear. Vin slumped down on the floor of the bathtub, resting in the white puddle. Her hair was drenched, skin slick and slimy.

She lay there for a while, breathing slowly, until her strength had plenished and the pleasure subsided. Eventually, she sat up again. She crawled over to the faucet and let the water fill the tub.
