The woman's finger dragged down the depths of her cleavage and over her smooth belly. She could feel the slight sting of the scratch that now trailed down her body, adding to the numerous cuts already suffered. Vera's eyes now had a dreamy look to them much like Miss Steel's. The venom left her thoughts clouded with nothing but thoughts of lust and need. Only the metallic woman mounted on top of her could bring her the relief she so desperately needed.

Vera's nails dig into Steel's sides. As the monster trailed soft kisses down her neck, her fingers dragged up and down the creature's sides. She knew pain was this monster's bliss so the Head Girl did all she could to make her nails sink into the glistening grey flesh.

Her fingers slid over the grey woman's back. "Ahhnnn.." Vera's eyes flutter wildly as the long rough tongue dragged just over one of her hardened peaks. The slight graze sent her pulse pounding, filling the already puffing areola with more boiling blood. The student's hazy mind was so focused on her breast that she was caught completely off guard as heated fingers plunged into her sex. Toes curl as juices flow like a river, nearly sizzling on the hot furnace floor.

"Uhhhnnn.." She groaned but the monster had suddenly stopped. Fingers were inside her still but the metallic woman was like a statue as she asked for guidance. Vera's hips rose off the floor, grinding into the monster's hand. "Nnngh... More... Please... So hot," she moaned, "My breasts... My body... Use me.. Make me feel good.. I need it so badly..."

"Yes, ma'am," Steel whispered warmly as her body built smoothly back into motion. Fingers slid and squirmed within Vera's depths, intuitively seeking the most tender points. The long, gray tongue ran back over the swell of the head girl's soft chest, passing along one tender nub and circling around to the other, then repeating its serpentine path erratically with pauses to tease at one nipple or the other. Miss Steel dug her other hand deeper into the floor, something starting to reawaken on seeing a squirming, moaning young woman beneath her, but the urges remain stifled by deeper instincts.

The fingers toying with Vera increased their strength and speed quickly until they were stirring the pale woman almost to a froth. Suddenly, they slowed again, but this time did not stop. Instead, they pressed harder into the student, working her flesh more deeply and less fervently.

"How's this, M- Mistress?" the gray woman purred, a strange stutter in her words, between long licks. Her fingers built up speed and lost it again, settling into a rhythm overlaid to vary between the two extremes.

Something stirred in the next room, sounding distinctly like a heavy body being dragged across the smooth floor, though if the gray woman noticed she paid it not heed.

"Ahhhhnnn..." She gasped as the heated metal that was Steel's tongue dragged and flicked over her swollen nipples. Vera's body arched further, pressing her large mounds against the monster's lips and tongue. Blood throbbed inside her tender peaks, sending forth waves of heat rippling through the rest of her quivering form.

The sound of her own groans of pleasure dulled the sound of the floor cracking beneathe Steel's metallic fingers. The Head Girl was not concerned about anything anymore. She could only think about the fingers pumping inside her dripping folds. The digits gradually sped up, churning her insides as the sound of juices slurping in and out of her sex filled the room.

"Nnnngh!" her hips slowly rocked against the monster's fingers. The creature began to work slower, taking her time as the metallic fingers dig into her soft insides. Her muscles twiched and clinged to the massaging fingers as her musky fluids soak over Steel's hand. "Ahhhnn!" she cried out in shock as the tempo changed from rough massage to furious pumping at random intervals.

"S-So... Mmm... So good.." she praised the metallic woman as she continued to call her mistress. The title purring from Steel's lips was enough to send a pleasing shiver through her entire body. Her own ego was being stroked by a monster, something she never expected before. She never had an encounter and deal with a monster go so pleasantly. Though if that will remain is still in question. The Head Girl did not mind either way. She was too focused on the tongue dragging across her nipples to notice something else moving about the room.

The gray woman smiled around her inhumanly long tongue at the praise, encouraged by it. The damp muscle curled its thin tip tight and flicked teasingly back and forth, rapidly, to tease across Vera's left nipple. It paused and wrapped around the the delicate nub to pinch and tug, then softly twist, before it released its hold and slithered down between to repeat the process on the other side.

As the tongue performed its work, fingers continued to dig and tease within the pale woman in their layered rhythms as a practiced thumb added its own enticement to the motions. As the speed within built strong, the gray woman's thumb trembled and flicked against Vera's clit as if electrified. When the fingers slowed and deepened their pace, the thumb followed suit. The changes, it became apparent, were timed to disrupt the stimulation as close to Vera's climax as possible, teasing her up right to its edge and varying to back away again and again.

Miss Steel panted, her eyes glazed with lust breathed from the air, lingering in the scent of the pale woman's sweat. Steel shuddered and bent herself fully into her task, her lips coming down on one breast as her tongue flickered across the other nipple, and her fingers building strong up within Vera once more. Yellow-green eyes turned up to try and catch Vera's, softly pleading for the head girl to accept the pleasure being offered to her.

The monster's long tongue continued to drag across her heated flesh. Every nerve stood on end, eager to feel the metallic woman's touch. Her breasts pulsed in sync with her rapidly beating heart sending forth more waves of heat throughout her body. Vera's body arched off the floor, thrusting her full mounds into Steel's face. The tongue skillfully wrapped around her puffing areola and closed around her swollen peak. Every tug and twist sent jolts of pleasure and pain deep into her chest and into her very core. The student's head rolled back as the creature continued to play with her body.

Hips rose, grinding against the monster's pumping digits. Eyes fluttered and slowly rolled back in her head as loud blissful moans filled the air. She could feel every muscle tensing up in anticipations. Her tight passage clinged desperately to Steel's fingers in hopes of getting just a little bit more stimulation to send her body into oblivion.

Vera's fingers grab hold of Steel's grey hair and pulled the woman's lips to her own. The Head Girl kissed the monster deeply and with passion. The venom continued to cloud her entire system in lust and need. She wanted nothing more to embrace this creature and feel the full extent of pleasure being offered. "T-Take me.." she groaned wantonly, "I want it.. I want you..." Her eyes were completely clouded over. Fingers stroke over the metal woman's breasts as she gazed into the being's yellowish eyes.

The gray woman nodded quickly to the request, sliding the fingers out of Vera. Steel settled herself between the pale-haired woman's legs as a thick shaft formed between gray thighs and poked gently at Vera's entrance. The tongue still dragged its pattern over the sensitive flesh as Miss Steel bent closer down to whisper with surprising clarity into Vera's ear.

"Please... hurt me," the monster begged. "Rip my skin off with your fingernails. I need it," she panted. As if trying to earn her request, Steel pushed slowly and steadily into Vera, filling her completely with the hardened member. It pulsed slightly inside the head girl, bulging out to squeeze against her walls until it feels as if they'll tear. The tongue snaked back into gray lips.

The gray woman pulled back slowly, leaving only the head of the cock within Vera, then thrust deeply back into the white-haired woman. Steel slid back again and pumped hard into Vera, settling into the smooth rhythm. Tender lips brushed and pulled at Vera's neck in time with the thrusts, and the gray woman's chest pressed into the pale woman's with each hard rock.

Vera's hips tried to follow the monster's retreating digits. Her glassy stare looked up only to widen at the sight of the large grey shaft growing from between the creature's thighs. Erotic visions of being impaled on the thick trunk flowed endlessly through her thoughts as she began licking her lips in anticipation.

"Nnngh! Uuuhnnn!" Her body arched as the searing hot rod pierced into her body. Her tight passage was forced slowly apart as it made progress little by little with each new entry into her trembling form. Arms and legs wrapped tightly around the metallic woman, holding on for dear life as the swelling member pushed deeper and deeper into her very core.

Eyes fluttered as she felt the pulsing meat grow even larger inside her already stretched folds. But Vera did not resist. In fact her long legs pulled herself closer, impaling herself further on the monster's cock. Her nails digged into Miss Steel's back as much as possible before slowly dragging outwards towards the woman's shoulder blades. Her head rolled to the side, exposing her neck to the tender lips of the beast. Her own lips soon found their new home at Steel's neck as she began to lick and suck gently before finally sinking her teeth into the grey flesh.

The gray woman thrust forcefully enough into Vera that the head girl's back slid slightly on the smooth concrete as soon as fingernails dug into gray skin. Panting, moaning breaths rolled so hot over Vera's shoulder and neck it felt as if her skin would blissfully sear from the attention. Miss Steel clutched the pale woman tight and fucked her ever more vigorously. Their hips slapped together sharply, painfully, which only drew more moans and cries from the gray woman.

Gray fingers clung to Vera's back, digging deeper into her flesh, and pulled the woman down to meet the thick cock pounding mercilessly into her. Small points of yellow welled under Vera's fingernails, sending further waves of painful pleasure through the gray woman's quaking body. The two of them crashed together, kissing and licking tenderly at each others necks for a long moment. The shaft pulsed and twitched with each deep thrust, bumping erratically against the tender parts of Vera's walls.

When the pale woman bit down, the gray woman screamed with lust, her head thrown back to keep from completely deafening Vera. The cock exploded, flooding over within the Head Girl almost immediately, as an intense orgasm nearly rent Miss Steel's body from within. Her hips didn't pause, even for a moment, during the release. Her body continued to drive down into Vera's, pressing hips sharply to hips and grinding breasts into breasts, as Steel devoted herself to bringing her new Mistress to a similar release, or perhaps ten.

Faintly, the door to the furnace room creaked.

Steel's scream sounded the creature's climax as molten monster seed began to fill her passage and womb. Nails dig in deeper as a loud cry sounds from Vera's throat. Juices gush forth, mixing with the thick ooze as the monster continued to pound through both their blissful release. "Ohhhnnnn! Y-Yesss! Yesss!" she gasped breathlessly, "Don't stop... More... I need more..." The venom kept her body hot and ready for more as the climax tore through her entire being.

The lewd slurp of their sexual juices sound with each thrust and of the metal woman's hips. Thick globs of white cum and juices oozed over her belly and down the crack of her ass. Vera's lower body was completely off the floor as the powerful creature continued to pound her lust into her still spasming form. Her climaxing folds clenched and relaxed over and over again, milking the woman's cock for all it was worth.

"Uuhhhnnn!" Her thighs tightened around Steel's body as her nails dug in and held for dear life. Each thrust sent ripples of searing pain and heated pleasure down into her loins. Her heart could be felt pulsing rapidly within her heavy breasts as they mashed and molded against the other woman's.

Already her body was tensing once more, reaching another wonderful breaking point as the metallic being showed no signs of tiring. Vera's mouth hung open as she let forth long blissful moans and screams of pleasure with each brutal thrust into her body. The Head Girl did not think but only reacted to her deepest carnal desires. Her arms pulled her up once more as her lips mashed up against Steel's. Her tongue pushed inside and began to lash and wrap around the other woman as moans rippled down each other's throats.

Miss Steel clutched Vera so tight in the rough embrace it threatened to almost break the head girl's ribs. The gray woman broke the kiss with a hungry gasp, panting hungrily, her lips damp with saliva. The long gray tongue lolled out of her mouth as she kept pounding into Vera, inhuman eyes twitching with pleasure. Steel clenched her eyes shut again and tensed, another release starting to well within her larger body, and threw her head back and her lips open.

"Mistress!"

Except the voice wasn't Steel's. The gray woman froze, her entire body turning stiff and motionless aside from her face, and smiled sheepishly at the six-armed, blue-scaled serpent woman standing in the doorway. The gray woman bit her lip for a moment, then grinned and tilted her head to one side.

"Hello, Zinc. Is something wrong?" Steel asked.

"Yes! The young lady has things she needs to do, and there's a poor student sitting in there looking very confused! I made her a pot of tea and tied her to the chair to make sure she wasn't bored, but she's owed punishment for a lot of truancy and I have to take care of... other things today!" the blue marilith said, the chains on her head rattling slightly as she glared at Miss Steel.

The gray woman looked back down at Vera and softened, dipping down to kiss the Head Girl on the cheek.

"I presume you can find your way out from here. Remember our deal, lovely lady," Steel whispered. She pulled her shaft back and hustled away from Vera, stepping through the door and pulling it shut with a loud clang. The pale-skinned woman was left alone, stripped, and filled with cum in the dark, warm, dry hallway.

"Ugh.." She gasped and pawed at the monster's back as the held grew tighter. The Head Girl felt like she was going to break in half as more and more pressure was put on her back and spine. But none of that ended the mood. Hips kept pounding against her own, filling her with Steel's searing rod. With the air being squeezed out of her, she could only gasp breathlessly as her body continued to twitch and spasm violently. Perhaps this being was going to fuck her to death at this rate.

The new voice that called out the same title she had earned filled the room and just like that everything froze. The rod was still halfway inside her. Her passage was clinging tightly around it for dear life as cum and juices oozed out around her spread netherlips. She was not familiar with a creature named Zinc. Glazed eyes looked up at the snake woman, it was rare to see monsters working together.

She was uncertain if she was glad or disappointed that their embrace had to end. But Zinc was right, she did have alot of work to do. A soft kiss to her cheek said Steel's goodbye. There was no doubt they would meet again with their contract now sealed. Vera would provide this one with the most troublesome of students for the metal woman to break and mold into proper students.

"Uhhnnnn... Y-Yes..." was all she could manage to say as the cock slurped out of her abused body. Basking in her afterglow, her entire body ached and her wounds stung like fire. Just like that, she was left alone in the furnace room, nude and covered in sexual fluids. It took several minutes for her to regain enough strength and sense to rise to her feet. Her uniform was still where it was. But first she needed to clean up.

Vera walked into the room where they made their agreement and used the spout that provided the cool water from before. She took her time cleaning her body as best as she could before picking up the metal spider and taking it back to her clothes. From there she dressed up and was ready for duty again. Being mid day already, she had alot of catching up to do and she still needed to drop this spider off back at her suite. Sighing softly, she stepped back into the dark halls of the basement and began the trek back to work.
