Tv Tropes Writing Challenge - Trope 5: Sexbot

About 4 years ago now two other writers, Lucianite and Rakked, decided to take a writing challenge and write smut based around Tropes found on Tv Tropes for a week. Here are my entries.

This time the trope I'm writing about is Sexbot.

In any case, I hope you enjoy it! This is the first story I’ve written involving robots, so enjoy. And yeah, it’s set in the Nex Starshine universe again. What can I say? I want to write more about the little blue shortstack but haven’t had a lot of time to do it lately, so I might as well build her world a little more.

Contains: M/F, alien dude, robot girl, huge cock, breasts expansion, huge breasts, hip growth, big ass, excessive cum.

Enjoy!

Tv Tropes Writing Challenge - Trope 5: Sexbot

Ging 08 was a small mining colony at the edge of civilized space, too insignificant for any of the larger corporations to take an interest in and too poor to buy robotic workers to mine the ore. So the work had to be done by the short, stocky Grewd, who could harden their skin and were such experienced miners in the past that the humans had given them the nickname Space Dwarves. As well as the Karlem, tall musclebound humanoids with thick plated skin who were often used for manual labour. All in all it was a boring planet, there weren’t a lot of women around and the pay was bad. But it was all the work most people could find.

Kirn was one of the Karlem that worked in the mines all day with old-fashioned mining lasers, digging up ores to sell to passing merchants. Right now his work day was finally over and he stomped back to his small apartment in the Canary’s Cage complex. Once he arrived the elevator was already packed with his colleagues so he took the stairs instead, all while grumbling to himself. But when he saw someone standing in front of his apartment’s door when he reached the fourth floor his features lit up. This was because the person standing at his door was carrying a package, a huge package from Aphrodite Industries which he had waited a long time for.

So the Karlem quickly ran to his apartment, giving the poor human delivery guy quite a fright. Kirn was nearly 9 feet tall with thick black plates covering his body, with grey skin peeking out between the slits while dark orange eyes excitedly stared at the small human. It looked like the delivery man was about to run away so Kirn slowed down and raised his hands while his wide mouth stretched in a friendly smile, the Karlem didn’t show his teeth because the pointed white fangs always seemed to freak the smaller races out.

‘Would that package be addressed to Kirn Marsten?’ He asked in a deep, rumbling voice.

‘Y-yes!’ the delivery man squeaked.

‘That would be me.’ Kirn rumbled while pointing at his name sewn into his overalls.

‘Si-sign this!’ the delivery mean stammered as he handed Kirn a digital clipboard and a pen. When the Karlem grabbed it a small box lit up.

As Kirn put down his signature, he noticed the human staring at him. He knew his kind looked strange to humans; his grey head was covered with small, spike-like plates that acted both hair and protection. Meanwhile, the rest of his head was the same shade of grey as the rest of his unprotected skin. His broad, powerful jaw and chin had a few, barely visible black spikes but that was it. Once he jotted down his signature he had to clear his throat before the delivery man noticed and retrieved his clipboard.

‘We-well, everything seems to be in order sir,’ he stammered. ‘Have a nice day!’ he added with a squeak before quickly finding his way downstairs.

Kirn shook his head. ‘Humans…’ he grumbled to himself. Either they were scared of him, or they wanted to experience what it was like to be screwed by some giant alien.

The Karlem didn’t let it bother him however, while humming a nonsensical, but happy, tune to himself he stuck his keycard underneath his apartment number causing the door to hiss open. He quickly pushed his package inside, and closed the door behind him. He had been waiting ages for this. Saving up parts of his paycheck and eating little food for weeks, at times even being late with the rent. But he was certain it was worth it! After locking the door and closing the curtains, as well as removing the battery from his holo-phone, Kirn began to unpack.

Inside was a figure around 5 foot tall made out of thin grey cables that were warm to the touch, an orb the size of the clenched fist of a human sat in its chest cavity with a few small buttons on it. The head was hairless with a set of dark, dimmed eyes and a pale pink, almost white, latex coating. Next to it was a small info stick with the words Aphrodite Industries Companion Droid, Mark V Instruction Manual written on it in small letters. With a grunt of annoyance Kirn started up his computer and pushed the info stick in the slot. For the next half hour he read through the information that appeared on the holo-screen about how to start up his Companion Droid, how to charge it and how to keep it clean. Although depending on the freedom you gave it, the Companion Droid could do most of those things by itself.

‘Finally,’ Kirn growled as he finished reading the manual and got to his feet. ‘Time to start you up, little lady.’ He muttered to himself as he gently tapped a few buttons on the orb in the Companion Droid’s chest cavity.

As soon as his thick finger tapped the last key, the orb began to glow with a vague purple light and the head shot up, much to Kirn’s surprise. ‘Scanning…’ said an emotionless voice as the eyes of the Companion Droid lit up with the same purple light as the orb. It seemed to be taking in Kirn’s form, once it was done the Companion Droid’s eyes dimmed again. ‘Scanning complete…analysing data…Karlem male. The gender chosen for you is female, do you agree? Yes or no?’ It asked in the same emotionless voice it had used before.

‘…yes.’ Kirn said after a moment of silence. He had read this would happen, but it still freaked him out.

In response the rest of the grey cables whipped out of the box while the purple orb began to glow pink, they seemed to form a vague sort of skeleton before a strange white goo began to leak from barely visible holes within the cables. Kirn’s eyes widened as before him the body of his Companion Droid was formed, grey, lifeless cables turned into small, dainty hands and slender graceful arms. Thick, black hair sprouted from her formerly bald head while her eyes lit up pink and her face slowly morphed into something a supermodel would be jealous of with plush, dark lips, a slender jawline and high, thin cheekbones. When the transformation came to an end, the Companion Droid’s face looked feminine enough but her chest was flat and her hips barely flared out.

‘Customer, please state your name.’ The droid said, still in the same emotionless tone of voice.

‘Kirn Marsten.’ The Karlem responded.

‘Approved,’ the droid said, before her voice shifted into a low, smoky feminine voice. ‘Hello Master Marsten, thank you for purchasing me,’ she purred as she stepped closer. ‘Do you approve of my appearance? Or do you wish for me to change? My body is very adaptable, so don’t be afraid to ask.’ She said while smiling with her plump black lips.

‘Well, eh, what do I call you?’ Kirn muttered.

‘Whatever you want, my Master.’ The droid replied.

‘What about…Cassie?’ Kirn suggested. It was the first name that had come to him.

‘Alright Master Marsten, from now on I will answer to the name Cassie,’ the droid replied in the same smoky voice. ‘Now, is there anything you want to change about me?’ she asked with a friendly smile.

Kirn was silent for a few moments before he rumbled. ‘I would like you to make yourself as curvy as possible.’

‘Understood, Master.’ Cassie replied, and the Karlem was certain he saw her glowing pink eyes twinkle impishly.

So without saying anything else, the Companion Droid grabbed her thick black nipples and pinched them softly. As she released a soft, pleasured moan her chest began to swell. At first it barely looked like they were growing at all, but before Kirn knew it they were the size of lemons, then oranges before reaching the size of grapefruits. Cassie was releasing soft, pleased little moans during the growing process and it all made the Karlem’s overalls feel a little tight. But Cassie’s curves didn’t stop growing while he was busy stripping out of his overalls. Pretty soon her breasts were the size of melons, and her hips began to grow wider as well while her thighs thickened at the same time.

When Kirn’s overalls were off Cassie’s breasts were larger than watermelons but still sat high and firm on her chest, capped with thick black nipples. The massive globes cast a shadow over her almost impossibly slim waist, which flared out in a set of perfect baby bearing hips and huge, perfectly rounded buttocks. Thick thighs went over in slender, but strong-looking, legs before ending in small, dainty feet. At the sight of it the plates between Kirn’s legs shifted to reveal a slit from which a long, fat red cock pushed. It was nearly as thick as one of the Karlem’s own wrists and ended in a pointed tip. With a growl he stepped up to the perfect little sexbomb that was his Companion Droid, but before he could pick her up and use her for the reason he had bought her he felt a, surprisingly warm, pale, latex-covered palm pressing against his broad chest.

‘Although it pleases me greatly that you approve of my new appearance, I must ask you to calm down and let me measure the size of your member first, Master.’ She purred with a faint smile on her lips.

‘How will you do that?’ Kirn rumbled while he cocked his head quizzically.

‘Simply insert your penis into my mouth.’ Cassie replied, with another impish glimmer in those glowing pink eyes of her as she stretched her lips until they formed a lewd “O”.

With a shrug the Karlem pushed his pointed cockhead into her mouth. When Cassie made no sounds of protest, he continued pushing his hips forward. Cassie’s throat began to bulge out as Kirn’s massive member was pushed further and further, but still she didn’t gag or release any other sounds of discomfort. Kirn released a pleasant growl after he managed to sink every last inch of his monstrous cock into the Companion Droid’s slick throat and felt a few strings of precum escaping from his distended cumslit. Cassie swallowed it effortlessly, however. The two of them stayed in this position for a while, but before the Karlem could ask if she was finished Cassie began pulling her head back.

A happy sigh escaped Cassie’s mouth after Kirn’s cockhead left her gob with a soft *pop*, strings of lubrication suspended between her plush black lips and the Karlem’s huge, thick red shaft. ‘My, my Master Marsten, you are quite a big boy,’ she giggled. ‘But I think I’m ready for you now…’ she added with a sensual purr.

It was all Kirn needed to hear. With a fierce growl he grabbed the Companion Droid’s big, cushiony buttocks and picked her up. Cassie giggled at his eagerness, but her giggling quickly turned into a low moan as the Karlem’s big, pointed cockhead pushed against her plump, drooling pussy. Thick strings of lubrication escaped her snatch and Kirn allowed it to run down his monstrous shaft, Cassie writhed in his grasp eager to be penetrated. But despite being a robot the Karlem didn’t want to be too rough with her during their first time. Once his massive member was shining with the Companion Droid’s lubrication, Kirn began to slowly push her down on his throbbing dick.

Both Kirn and Cassie released a pleasant moan as her dripping slit stretched wide around his member, it had been ages since the Karlem had gotten laid so his member gave a sharp jerk inside the Companion Droid. Cassie only moaned lewdly and showed no signs of discomfort, instead her folds coiled around Kirn’s fat pole a little tighter, squeezing out a few more strings of precum. In response he gasped for air and didn’t move, but as he got used to Cassie’s tight, wet cunny he continued pushing her down on his dick. Short, pleased little gasps escaped Cassie mouth as she took in more and more of the Karlem’s monstrous pole, even when her stomach began to push outwards due to the size of Kirn’s member she continued to moan in pleasure.

‘You do not have to be gentle with me, Master,’ Cassie said softly as her pussy tightened around Kirn’s huge cock. ‘My body can take a lot.’

‘Don’t say things you might regret later down the line.’ The Karlem shot back with a fierce grin, while he squeezed the Companion Droid’s big, cushiony asscheeks and pulled her down further on his throbbing pole.

Cassie released a pleased little whimper and her coiling cunny released a lewd squelching sound as she showered the Karlem’s massive member with its lubrication. Kirn chuckled in response and pulled her a little closer, releasing a low growl as her huge breasts flattened against his muscular chest. It wasn’t long before the entirety of Kirn’s monstercock had disappeared into the Companion Droid’s depths and strings of artificial saliva were escaping the corners of her mouth. Cassie twitched happily in the big Karlem’s grip as his huge cock filled her up completely and throbbed against her folds, but Kirn wasn’t done with her yet.

A soft growl escaped his lips as he slowly pulled the Companion Droid up, but when half of his monstrous shaft had been extracted he dropped her down on his member again. Cassie squeaked in pleasure and glanced up at Kirn adoringly, before she began peppering his chest with wet, sticky kisses. Kirn responded by grunting in approval while he began to fuck Cassie, slowly at first but it didn’t take long before he picked up the pace. It wasn’t like Cassie cared however; the rough treatment only seemed to get her off. Releasing mewls and squeaks between her kisses while her wet, twitching cunt did its best to try and milk the Karlem’s beastly pole for its cum.

As it turned out, it didn’t take Cassie long to get the Karlem’s cum. After Kirn bounced her up and down his shaft a little longer, with the Companion Droid’s lubrication running down his shaft and smacking on the floor, he felt his orgasm rapidly approaching. Cassie’s moans began to grow louder and sharper as the throbbing of Kirn’s member increased; eventually she bit down on Kirn’s shoulder as her cunny spasmed tightly around the Karlem’s huge prick. Just in time for the Karlem’s own climax to approach.

‘CUMMING!’ Kirn roared loud enough to make the other tenants to hear.

Cassie’s belly began to swell due to the massive outpouring of Kirn’s spunk, most days he’d been too tired to even masturbate so he had been saving up for a long time. Cassie didn’t seem to mind much as her eyes flared a little brighter and her body twitched a little wilder in the Karlem’s grip. Hot, sticky semen quickly escaped the Companion Droid’s cum-stiffed snatch as her growing stomach pressing against Kirn’s own stomach. Once he was done, a mixture of Cassie’s lubrication and his jizz had formed on the floor, and the Companion Droid’s mouth hung open in pleasure.

‘Di-did that please you, my M-Master?’ Cassie gasped as Kirn pulled her off of his hard, monstercock. Once the Karlem’s cockhead escaped the Companion Droid’s snatch, her gaping pussy abruptly tightened up again.

‘You bet you did,’ the Karlem replied with a grin. ‘I haven’t felt this good in ages! As soon as you’re up for it, we should go for round two.’ He added.

‘It will be but a moment, Master.’ Cassie purred as Kirn gently placed her on the bed.

While she lied on the bed with a swollen tummy the Companion Droidgrinned broadly and Kirn watched with amazement how her stomach began to flatten, instead the extra fat seemed to go to her hips and buttocks. Once it was gone, Cassie spread her legs invitingly and it was an invitation the Karlem would be all too happy to take advantage off. With a toothy grin he grabbed her broad hips, and slammed his monstercock in her tight, dripping depths once again.

For the rest of the night, happy feminine moans and loud, deep, male grunts combined with the sounds of flesh slapping on flesh echoed through Kirn’s small apartment. Although, unfortunately, due to the thin walls it meant his neighbours got to enjoy the sounds of their passionate lovemaking as well. Suffice it to say, Kirn wasn’t in the best shape when he went to work the next morning and was already looking forward to going back home to Cassie as soon as he stepped outside.

THE END.
