Heyo! This is a new story I've decided to give a shot to. I want to try writing something a little darker and definitely more mature. This is rated M, as you know, meaning there is explicit content of sexual nature. I'm not kidding, it starts off immediately and gets worse from there. This character was also sorta created by Leonixon, just to be sure I give credit where it's due.

Hope you enjoy it! I own nothing except my own OC's.

How many times more was she going to have to call his spike magnificent when, in all honesty, it was a B-? Scratch that, C+ at best. Giving him a B was being nice and being nice got you nowhere. That's not how you survive.

These were the thoughts going through a femmes mind, Crystal, while the mech above her grunted and groaned as he repeatedly rocked his hips into her. He reeked with the stench of dried energon and appeared to refuse to step into a washrack before he came knocking on her door. Crystal had seen this one before, and if his exuberance and eagerness to get inside of her was any sign, she assumed he had just won a good match. Gladiators had femmes like Crystal as entertainment and that was about it, thus she could be sure any brute with a winning streak could be heard through the thin walls accompanied by vicious pounding of metal on metal.

As was her current situation. Unfortunately, she was so caught up in her inner monologue that a large hand gripping her face and slamming it against the berth was the only way to rip her out of it.

"What, ya bored? Not good enough for ya? I don't remember telling you you could stop talking." His breath was hot and stung her olfactory sensors worse than his body odor. Her processor and mouth hurriedly attempted to reconnect and talk her way out, but the hand that was slowly squeezing her face harder and harder with each passing second was making that difficult. Crystal couldn't allow her face to be dented, it was bad business.

"No, no, not at all! You're so good, I can't think of what to say, I just get speechless! Please, I'm so close, please don't stop!" Her hands scrabbled along his playing desperately while she undulated her frame underneath him, squirming and whining for more. How humiliating.

"That's what I thought." He sneered, moving his hand to her throat and restarting his brutal rhythm. "You bots, can't ever get enough. Lucky someone like me can give it to you like this. Valve so wet I might just slip out." His smile was cruel and his excuse for dirty talk was broken up by his panting. Crystal bit her glossa to prevent herself from telling the truth. All pleasure bots were programmed to lubricate on command. A few more pleads for more, a few more stabbing thrusts and he bowed over.

Something she was well acquainted with seeped into her. It was warm and thick and it made her shiver in disgust. Thankfully, this mech didn't believe in afterglow or extending his stay any longer than he needed to. He pulled out, tucked himself away, and cast a few credits across her heaving frame. "No need to thank me. I'll be back before you know it." He flashed her a crooked smile and a seedy wink.

"Thank Primus." Crystal cooed, shuttering her optics in a dreamy gaze. He sauntered out and her face fell. "Thank Primus it's over." She muttered, sitting up straight to immediately inspect her valve. A silvery liquid oozed out of her but she ignored it, prodding her walls and feeling for any tears or signs of stretching. She would be sore, no doubt about it, but her valve was in tact. A blessing when your clients were all murderers and killed for money.

Crystal stood up and stretched her arms above her helm, straining upwards until she heard a satisfying pop. She sighed in relief, rubbing her hip strut that had popped out of alignment from his constant hammering. She walked over to her door and peeked outside. Nothing but dim lighting and moans echoing off the dingy walls. Crystal closed the door and flicked the switch that turned off the light hanging over her door. It alerted potential customers whether they were available to service you or not. She would've clicked off the light prior to the dirty mech had he not practically shoved his way inside and immediately taken her to the berth.

Crystal scanned the room and vented in deeply in a sigh. She regretted it, realizing the stench was staying stagnant in the unventilated space. Crystal walked over to a small fan in the corner and turned that on to try and circulate the air. It was worth the absurd amount of credits it had cost, especially when nights got warm. The room itself was dirty and Crystal was under no delusions. She lived in filth.

However, it was her filth for the foreseeable future and she would make the best of it. She knew a couple femmes that just let their room go and then wonder why their clientele suddenly dropped. People bought things with their optics first. No one buys a glass that looks broken or adopts a pet that looks sickly. Presentation was everything. To an interface slave, it was their life. The room was without clutter and she always slept on a berth. Crystal bought another berth sheet the minute she could afford one. One for fragging, one for sleeping.

Crystal grabbed a bag tucked under her berth and dragged herself out the door towards the wash racks.

A cloud of perfume lethal enough to gag someone hit her, but at this point everyone was so used to the smell. She nodded her helm tiredly to a few femmes washing up. She took up a stall and began her ritual. First, it was washing her frame of the buildup of grime that occurred throughout the day. She scrubbed and polished and did a few paint touch ups, always maintaining delicate care to every detail. Her rose color was prone to noticeable paint transfers and was pit to take care of, but it was appealing and feminine.

Crystal took a deep breath before sitting down and spreading her legs wide. Unscrewing a jar, she took a thick glob of an even thicker creamer and spread it around the walls of her valve, making sure to get every nook and cranny.

"Anyone seen Bluebird?"

"Nah, still finishing up I think."

"Damn, I need her hands for this."

Crystal calmly listened to the chatter inches away. There was no privacy in these halls, and they didn't need any. Crystal was as relaxed as could be with two fingers in her valve while femmes walked outside the open stall. The door opened and in walked a navy blue bot. She had the body of a dancer and most likely the flexibility of one.

"Hey Blue, can you-" She was cut off by Bluebird frantically holding up a waving finger with a hand over her mouth. She hurriedly walked to a stall and a heaving purge echoed in the washracks. "You know what, never mind."

Crystal gave a small chuckle to herself, removing her fingers and wiping them off on a rag. "Hey Blue, how'd that spike taste?" Crystal called out.

"Frag you." Came a ragged wheeze, followed by another purge. Crystal laughed a little louder. Blue came by and plopped down on a bench outside her stall. "Whatever that mech has been putting in his frame, I think his transfluid is reflecting it." She grimaced, wiping her mouth. Crystal reached into her bag and handed her a spray bottle.

"It'll numb you next time, you won't taste a thing." She gently advised, going back to her valve. Crystal took out a thin, flat object and proceeded to scrape out the cream in long, circular strokes. She inspected the mess and squinted. There was a tiny dark speck, something that was solid and moving.

"That fragger." She grit, plucking the mass out and crushing it between her fingers. "Fragging nanotick. How disgusting do you have to be to be infested with ticks and spread them to other people." She muttered to herself, now worriedly continuing her scraping to see if there were more.

"Who did it?" Blue asked, gently prodding a tender dent on the inside of her thigh.

"That one mech. Green, smells, thinks his spike is Primus' gift." A round of "ooh"s in recognition. That was the one and only tick she found. Ticks spread viruses and that wasn't good. Some mechs didn't mind considering the viruses they already had, but for others, it was a deal breaker. That cost them credits, and lost credits made a very unhappy pitmaster.

Pretty soon, her valve was cleaned, tightened, and given a quick spray to help with soreness come morning.

"Watching you do that every night makes me want to pass out. It looks so damn tedious." Blue frowned, turning her nose up to it.

"Well, I'm glad I'm what you think of when you recharge." Crystal smiled, spritzing herself with scented perfumes before packing her stuff up.

"Suck my spike." Blue retorted with no heat attached. "Then again, you'll be doing some of that soon enough." Crystal paused and turned back to her to see her grinning. "Pitmaster discourages showing favoritism, there, Crystal. Better watch it."

Crystal smirked. "It's not favoritism if I've never refused a client and always get paid in the end."

"Denial." Blue coughed into her fist, faking a few more. Crystal shook her helm, bidding a few femmes goodnight. Crystal returned to her room and sighed in relief to find that the smell had dissipated. She tucked her bag under her berth and changed her sheet before slowly coming to the light switch. She fiddled with it, unsure of whether to make herself available or close her body off for the rest of the night. She didn't want to deter a certain visitor, not when he paid so well and made her night well worth the slow start to her morning the following day.

She opted out of turning the light on. If he decided he wasn't in need of her services, she didn't want to invite anyone else. She turned off her own light and finally relaxed on her berth, already feeling the drowsiness kick in and weigh down her processor. Her optics must have been closed for a breem when there was a knock. Her optics snapped open as she stared at the door. No one in their right mind would knock on a door with its light out. There was potential that a gladiator already inside might come out and slit your throat for interrupting. Crystals spark pulsed faster in anticipation as she stood up and made her way to the door.

She gave a soft smirk when her door revealed golden armor and a tall, muscular mech that made her mouth go dry.

"It's rude to wake someone up in the middle of the night." She softly murmured, leaning against her door frame.

"And yet you still opened the door." His voice rumbled, sending a deep thrill down her spinal strut.

"What can I do for you?" She feigned innocence, tilting her helm as if genuinely curious as to why he was here. A smirk pulled at the corner of his lips.

"I think you know."

"And who's to say I can service you?" Her voice had dropped a volume level, heat licking at her body the longer she stared at him and thought of the services she could give him. The gladiator hummed, glancing at the darkened light bulb and then back at her.

"Perhaps I'll come by later, then." He started to turn away when she quickly flicked the light on. His smirk turned predatory and his optics darkened. He looked dangerous and she couldn't get enough of it. "That's what I thought." He stepped closer to her and she matched him in stepping backwards. Any closer, and she would have to kick her fans on prematurely. He continued walking, entering her domain and shutting the door behind them, enveloping them in darkness. Crystal was fixated on his optics, blue and startlingly clear.

He slowly walked them backwards until the back of her knees hit the berth. She subtly turned her helm backwards to see where she was and that was the one weakness she needed to show. A hand grabbed her wrist and tugged her forward against a warm chest. The other hand snaked around her waist and held her tightly against him. This all happened in an astrosecond and before she could realize it, her lips were covered by his. His kiss was demanding, insistent. It stole the air straight out of her cooling units and made her processor fog. The hand that wasn't currently in his grip cupped the back of his neck, pressing him closer and matching him kiss for kiss. A growl deep in his chassis was her warning before he moved down to her neck, toyed a cable with his glossa, and bit down down.

"Sunstreaker." Crystal breathed, trying to somehow close the nonexistent space between them to feel even more. "How do you want me?" She purred, nimble fingers dipping in and tracing his transformation seams.

"On your back. I want to watch you beg." Sunstreaker huskily vented against her audial. Her tanks melted in the intense fire burning her up. He hadn't even touched her yet and his voice alone was doing things to her that the previous mech couldn't do with his mindless pounding. She reluctantly let go of him and pushed him off of her before tipping backwards onto her berth, sprawling out and opening her frame for him to explore her however he wanted. He had her well mapped out by now.

Taking two thighs in both hands, he scooted them backwards, hovering over her and never breaking optic contact. His hands, a killer's hands, smoothed down her legs to her calves before coming back up again. He stroked the insides of her thighs, edging close to her panel that was barely containing the build up of lubricant inside. Sunstreaker knew how to build anticipation and make her impatient.

"Open." He commanded roughly, taking her knees and pinning them to the berth, spreading her wide open. Crystal's chassis was quickly moving up and down in the dark to help aid her venting systems as another burst of delicious heat crawled up into her spark.

"As you desire." She panted, panel quickly moving aside to reveal her valve in all its glory. Sunstreaker inspected her with an artist's eye as his optics quickly darkened to deep blue. Spread out on display, Crystal couldn't take the view of him gazing down at her and closed her optics, shoving her face to the side. For the second time that night, a hand gripped her face. Sunstreaker forcefully turned her back to look at him as he lowered himself between her legs, faces inches apart.

"Who said you could look away?" Sunstreaker quietly demanded, hand lightly wrapping around her throat in a light threat.

"N-No one." Crystal stuttered, hands trailing across his back and shoulders to try and coax him into returning his attention to much more important things, like the throbbing between her legs that begged for satisfaction. Sunstreaker let loose another growl from his throat and Crystal realized her mistake. "No one, sir. Forgive my mindless discretion."

Sunstreaker tilted his helm, carefully toying with a cable in her neck. "How badly do you want my forgiveness?" He rumbled, scraping the cable with the edge of his thumb. She shivered, legs trembling beneath him.

"Badly." Crystal whispered into his audial fin, hands tightening around his shoulders. Sunstreaker gave a small "hmm" and let go.

"Not good enough." His optics pierced into her own as he waited expectantly. He tried to rise up off her when she held him back down.

"Please, please, I want it! I'll do anything for it!" She started kissing along his neck and his jaw. "You know I would, you know all sorts of things I'll do for it." Crystal murmured, denta lightly scraping against the bottom of his fin. Sunstreaker snarled, pinning her back down by the throat again before kissing her long and hard. Her spark was spinning so fast in her chassis, she thought it might fly from her chamber. She was drowning in it, in him, his taste, his scent, his touch. She gave a slow grind into hips to remind him what he was paying for, moaning into his mouth. There was a quiet 'snick' before she felt something hot and hard right above where she really wanted it to be. She could feel her valve leaking and thought it such a shame that it had gone untouched for so long.

"You're driving me insane, just put it in already." Crystal groaned, optics pleading. Sunstreaker smirked, a small chuckle shaking his frame.

"So impatient." He purred, lining himself up. "So greedy." He hilted himself in one stroke. Crystals helm snapped backwards as she let out a long, high-pitched moan. Her valve quivered around him in exquisite joy. He slowly began a rhythm while continuing to hotly vent into her audial. "Such a loyal whore. Always so ready for me." Crystal couldn't focus on anything except the divine sensation of friction. The way he almost pulled out just to dive back all the way and reach so deep had her crying out, babbling words without reason.

"Good, so good, I'm always open for you, always." She gasped, her frame rocking in time with his thrusts that were getting harder. There was a wet squelching noise intermingled with the screeching of metal on metal that had Sunstreaker shivering. He went to no one else but her, and Primus did she deliver every single time. He paused to grind into her deep and slow before returning to his pounding rhythm. Her moans and cries of pleasure were like a sirens song to his audials, spurring him on further. He grabbed a leg and lifted it just so, changing the angle to allow his spike to brush hidden nodes that were no secret to him. Her volume went up an octave or two.

"Who do you serve?" Sunstreaker growled, feeling his overload approaching rapidly as her valve clenched around him and sucked him back in graciously.

"You, you, it's my pleasure to service you and my aim to please y-Ah! Sir, please!" Crystal begged, unable to stop her rolling hips even if she wanted to.

"Overload. Now." Sunstreaker commanded, crashing his hips against hers. Her frame seized up and twitched irregularly while her mouth stretched open in a silent scream. Her hands clenched the berth while a guttural wail escaped her lips, her legs wrapping tightly around his hips. Sunstreaker watched all of this unravel before he stiffened and groaned lowly, filling her valve with his transfluid. Crystal shivered, but this wasn't out of disgust. The golden gladiator collapsed on her, steam hissing out of cracks in his armor while he got his venting under control.

A few minutes of silence stretched on with nothing but their cooling fans blowing.

"So.." Crystal started off, softly kissing his cheek and jaw. "Does this mean I'm forgiven?" Sunstreaker lifted his face out of her neck and looked at her with a charming smirk.

"For now." He rolled them over, lightly stroking a hand up and down her back. Her hands calmly explored his chest and abdomen, his pleasure always coming before her own.

"To think I almost didn't open the door." She mused, focusing on paying special attention to his frame through her own afterglow tingles. Sunstreaker quietly chuckled, silently watching her. "Is there anything else I can service for you, tonight?" She questioned with a smile that crinkled the edges of her optics. His fingers gently teased the wires in her hips, making her jump.

"The usual." He answered. Crystal nodded, sliding off of his hips before cozying up to his side. Her hand slid around his helm to gently caress her fingers across the sensitive slats on his fins. She watched as his optics shuttered close and he let out a deep sigh. "How much this time?"

Crystal hummed while continuing her petting. "170." His optics reopened to look back at her.

"That's cheaper than last time."

"Consider it a discount."

"That's bad business practice."

Crystal smiled, shrugging. "Is it? As far as I can tell, you still show up at my door which means business is still booming." She gave him a lingering kiss before laying back down, tracing the outline of his audials. He wasn't the first mech to ever request staying in her berth to sleep, but he was definitely the most welcome. Come morning, there would be a neat pile of credits on a small table that would equal double the price she asked for. He was her best customer.
