“Okay Sweetie, how’s that?” Spike queried as he pressed down on the duct tape wrapped around his beloved robot’s mid-section. Sweetie looked at it, and closed her eyes as she flexed the synthetic plates on her back. The tape on them bulged considerably as the blaster cannons concealed underneath struggled to get out.

“Ummm… maybe one more layer? Just make sure I’m absolutely safe?” She asked with a nervous giggle. Spike looked at her funny, and tried his best to suppress his snickers as he wound another layer of duct tape around his marefriend’s body.

“I’m pretty sure when they taught you about the needs of ‘safe sex’ in health class, this isn’t what they meant.” He quipped, smirking as Sweetie giggled again.

“No, but it’s what’s important. The last thing I want is to ruin the mood of our first time by accidentally blasting you, or the room, to pieces.” The robot unicorn meeped, feeling her CPU fizzle as Spike finished applying the impromptu ‘protection’. She still detected that her body’s defensive measures could rip through the tape if she felt her life was honestly in danger, but given she couldn’t calculate any possible way the current situation could turn dangerous (at least without her help), she deemed it was an acceptable risk.

“I still think you’re worrying too much.” Spike sighed as he placed the tape on the night stand and lay back down on the bed. “You may have popped numerous blaster boners, but so far you’ve stopped yourself from actually hurting me. I’d say that proves we won’t have any accidents.”

Sweetie felt her face heating up as Spike took her frontal hooves, helping her climb on top of him.

“Well, save for the accidents we planned for.” She said, her circuits sizzling again as she settled down against her sweet dragon’s muscular front. Even now, when they’d spent so many days and nights cuddling together, the feel of those warm, smooth scales was still electrifying, more so now that she no longer had her synthetic coat and outer skin to act as barrier. She stared down at the dragon’s softly smiling face, feeling her heart pump and start to speed up as her nether regions began to grow wet.

“You’re really okay with doing this… and letting come what may?” She asked. The simple nod from Spike made every light on her body glow like a cluster of stars.

“You said you wanted to know if you’re capable of bearing foals. I meant what I said about wanting to give it a try.” He replied while cupping her face. “Regardless of whether you’re metal or flesh, whomever designed you wanted you to be able to fulfill all the parameters of being a normal pony. While Twilight may say we’re still young, it’s not that uncommon for either ponies or dragons to be having offspring at our age.”

Sweetie’s gaze averted as the intensity of her lights died down.

“Yeah, but a dragon and a robot pony together? That’s still introducing a considerable degree of unknown factors, and...”

The mare broke off as she noticed Spike’s gaze narrowing at her in the darkness.

“You’re right, I’m worrying too much. I’ll stop now.” She said, then murred as Spike leaned up to kiss her gently on the lips. “I just… like any mare who’s experiencing her first time having sex, I want this to be the best it can be. Something I’ll treasure every time I remember it.”

Spike smiled with notably more smugness as one of his hands slid down to the glistening folds between his marefriend’s legs.

“Well, it feels like you’re off to a good start.” He said, feeling his own heart speed up as Sweetie squirmed like she tended to do whenever he touched her down there. “A little cuddling and you’re already wet?”

Sweetie grit her teeth as she felt every fiber optic cable in her burn with the intensity of pleasurable data, all blooming upward from her loins.

“That… and the feel of your body… ngh… the realisation that I really do want this… that I’m ready for this...” She meeped, her voice crackling slightly as Spike slid his fingers in deeper.

“I’m ready and want this too, Sweetie. So long as you’re good to go.” Spike soothed as he kissed his mare on the neck. He made sure to be gentle, watching that he didn’t hurt Sweetie with his claws or his teeth. Granted, he wasn’t actually sure if he could, given her body had already proven durable enough to survive being incinerated in a fire, but then again, he’d never tried to be rough with the unicorn before, and thus there was no reason for him to start now!

“Oooh, believe me, Spike… when you start doing… mmmph… that… oooh, I am so ready!” Sweetie moaned as Spike lightly nibbled at her synthetic flesh. It really did amaze him how she still felt so soft and plush. Granted, she was smoother now, due to her coat having been burned off, but the synthetic skin otherwise felt real. It was as warm and tender as a pony should be, quite appetizing in fact! Not that Spike would ever dream of eating his marefriend… well… not in a final sense, at least.

Sweetie moaned again and wrapped her front legs around Spike’s neck as he traced her labia. His tail curled upward to help add to the stimulation, rubbing itself against the mare’s increasingly soaked sex as Spike moved to kiss over her chest. He could sense her growing want to get to the main part of the action, but at the same time, he wanted to thoroughly explore her body. Even if they had at least done this much together before Sweetie’s true status had been revealed, she now felt like a wholly new, and utterly wonderful being, one Spike wanted to memorise every inch of.

As he got to her barrel, Spike felt Sweetie tug on him, coaxing him to lean forward, and by extension help her to lie down on her back. He looked up to see her staring down at him, her glowing green eyes burning with the same desire he’d seen so many times after the two had officially become a couple. Smiling, Spike shifted forward and lay his beloved mare out on the bed, kissing her again on the lips as her legs curled away from him, signifying the dragon could do whatever he wished now.

What he wished was to see how much of a true mare his sweet robot was. Her sex felt real enough and hot enough to his fingers, but would it to his nose? To his mouth?

To his tongue?

Sweetie’s legs inadvertently kicked as she sensed her drake’s next destination. Spike grabbed them, and held them still as he closed in on what he desired. The heat of his breath was feeding that which coursed through the mare’s circuits, making her want to struggle all the more. She knew she could just temporarily disable her limbs, at least so she didn’t accidentally send Spike flying from a hoof to the face (that had rather soured the mood during a previous time of intimacy), yet the dragon seemed to relish having to hold his wild love down. Not to mention the feel of his dense, muscular arms, fighting against her well maintained mechanical strength, that felt good in a wholly different way.

By the time Spike applied his tongue to Sweetie’s petals for the first time, the mare felt that familiar sensation building up both above and below. The sense that her cranial CPU was about to hit critical from the overload of emotional data, as her nether regions exploded in that strange yet oh so deliciously satisfying sensation of heat and pleasure that ponies dubbed an orgasm.

Spike licked deeper into his marefriend’s folds, his mouth salivating as he found she indeed still tasted like he remembered. He directed some hot breath onto her pearl, feeling her sex ‘wink’ around his maw. Yes, down here, much like everywhere else, she was indeed a very proper female. Machine or not, she was capable of fulfilling every criteria that was expected of a mare, right up to the ragged moaning, and the muffled screaming as juice splashed all over Spike’s muzzle.

The dragon dug his claws into Sweetie’s hind legs, feeling them thrash and battle him with even greater vigor. His arms flared with purple scaled strength as he held those squirming limbs against the mattress, licking and cleaning Sweetie’s sex up before finally rising and beholding his blissfully panting love.

“Well, that took even less time than before.” He commented, getting a breathless giggle.

“Well, you’ve never used your tongue on me before… and it felt so much more intense without my epidermal covering… heh...” Sweetie sighed in relief as she beheld her dragon’s noble features. “At least this time I didn’t leave you with a black eye. Was kind of worried about that after last time...”

Spike snickered and shook his head.

“As I said then, dragons are supposed to be able to take a pounding. As presumably are robots...” He stated with a slightly more lewd tone. Sweetie felt her loins grow even hotter as she looked down to her gentledrake’s crotch, seeing the action had arisen that which had her both awed and feared at once.

“Are you ready to continue?” He asked, stroking the length of his ridged and knotted penis. Sweetie bit her lip, recalling that odd tidbit she’d read about in one of Twilight’s books on dragon anatomy. As a species whose entire existence was defined by how perilous their environment and their society was, dragons had evolved specific means to ensure that they had the best possible odds of conceiving when mating, both by stimulating the female to ovulate and also ensure none of their seed was wasted. While that was all well and good for when one dragon mated with another, it added a sense of considerable danger when one did so with a pony. The fact that Spike was exceptionally huge for his small sized body didn’t help either.

Sweetie bit her lip as the HUD in her eyes gauged Spike’s maleness and flashed several warning signs that taking it inside her was going to be damn risky. Silently she calmed herself, repeating her sweet drake’s statement that they were both durable creatures.

“Yes Spike, please, let’s keep going!” She said, forcing herself to look up at Spike’s eyes as he climbed on top of her. “And don’t stop, no matter what.”

Spike slowly slid his hands up along his marefriend’s body, taking hold of her front legs as he slowly lined himself up with her sex. Internally, the robot accessed the system for her pain receptors, preparing to switch them off if the next part hurt too much.

It certainly did as Spike began to enter her, though the angular shape of his cock helped a little. He still took his time, letting her get used to the gradual spreading of her petals as he pushed himself further in. More warning signs flashed across Sweetie’s eyes, but she simply dismissed them. This is what every mare went through during their first time, even if their lovers tended to not be endowed in the same manner. There was pain and blood, but both would only be temporary.

“Ngh… so tight… oooh, you okay?” Spike asked as Sweetie raised her face into his chest, letting his scent and his warmth quell her worry.

“Yeah… just.... ngh… I think you’re at my hymen… ngh… which means the next part is going to be the worst.” She said in a muffled voice. Spike looked at her in shock.

“You have a hymen?” He asked. Sweetie nodded meekly as red began to bleed through her ears. “Wait… so does that mean whomever created you also intended for you to also function as… as… uh… actually, you know what? I don’t want to know the answer to that.” Spike muttered as he caressed the unicorn’s mane. “Let… mmm… let’s just save that question for later.”

From between his pecs, Sweetie muffled a ‘thank you’. Steeling his nerves, Spike gripped the sheets with one hand while he stroked through the unicorn’s silky locks.

“You’re right though, Twilight says this next part is supposed to hurt the most, so if you need a moment...”

Spike paused as he felt Sweetie suddenly wrap both forelegs around his hips. With a strangled sob, the robot pulled him fully into herself, tearing through her hymen and also really stretching her outer lips as the knot entered her too.

“AGH… guh… Sweetie!” Spike gasped, feeling a sudden rush of both pleasure from his flesh being fully nestled in the warm, wet confines of his love, as well as fright that said love was also crying into his chest as the lights on her body flashed in a schizophrenic manner.

“Sweetie?” He looked down in worry as the unicorn extracted her tearful visage and hastily wiped her eyes.

“I’m… *sniff*... I’m okay. Just… ahhh… felt it was better to get it over with. Ngh… get past the hurdle.” She said, blinking as damage reports flickered repeatedly across her vision. Spike tenderly cupped her face, dabbing away her tears with his thumbs.

“You’re sure?” He asked. The mare nodded as the emerald glow of her orbs slowly returned to its usual hue and brightness.

“You’re my first now, Spike. You’ll always be my first. That’s what matters to me.” Sweetie said. “Whatever damage you’ve done, I can fix it. Just again, don’t stop!”

Spike felt his own eyes start to tear up. He brought Sweetie up to kiss her again, then carefully laid her down on the mattress so he could position himself to commence with the real action.

The first few thrusts brought more pain and blood, as Sweetie’s now deflowered treasure struggled to adapt to the size of her dragon’s length. Yet, as Spike maintained a slow, gentle rhythm, it indeed began to get better. Sweetie felt herself actually start to experience the pleasure that was supposed to accompany sex, albeit with some awkward starts and stops as the tape wrapped around her midsection kept catching on the sheets. She tried to ignore it but as Spike picked up the pace it began bunching up, causing him to have to thrust harder, then pause as he felt his mare yelp from her skin getting pulled, while her body stuck fast to the bed.

“Ngh… um… think we need to change position. Hold on.” Spike rolled over onto his back again, pulling Sweetie on top of him. “Let’s see if this is any better.”

He began to piston his hips upward, keeping a firm hold on his mare’s flank.

“Ooooh… ngh… y-yeah… oh Spike that’s much… ngh… sooo much better!” Sweetie moaned, feeling even less pain and even more glee. From this position, she not only had the pleasure of his measured thrusting, but also the visual feast of his muscles rippling and flexing with the effort. He might have been small of height, but as he was currently demonstrating, everywhere else he was big and powerful where it counted the most!

On his end, Spike was finding Sweetie to be the exact opposite, which just made it more perfect. Her body squeezed and smooshed around his length on each thrust, her hips and barrel giving into his secure grip like real flesh was supposed to. She was a marvel, just as she’d always been. The only difference was now she was even more so, because she was HIS marvel.

Gritting his teeth, Spike tried to maintain his rhythm, worried any lull in his marefriend’s moans meant he was doing something wrong. With this being his first time as well as hers, he couldn’t hope to dash all of his stage fright, more so with his wings and tail just wildly flapping about every time another bolt of pleasure shot through him. As both of them were learning, one could read all the romance novels and sex guides around to learn what to do during these most intimate moments, but that didn’t automatically make one a master lover.

“Ack! S-Sorry Sweetie...” The dragon blushed as his tail inadvertently whipped up and smacked the robot across her back again. “Ngh… didn’t think it’d be such a problem keeping all my extra limbs under control...”

Sweetie meeped as Spike suddenly lurched upward, causing her to almost fall off him. She looked down and giggled softly as the dragon stretched his wing back out from where it’d crammed itself under his back during one of his thrusts.

“It’s fine Spike… mmm… seriously.” She soothed, leaning forward to kiss him again. “This still feels wonderful, still lets me know I can be the mare you deserve… eeep! And… you’re not the only one who doesn’t quite know what to do with their body”

Sweetie looked behind herself as she felt the tape start to tear. Spike’s tail had weakened it with the smacks, and her blasters were now trying to take advantage and bring themselves into the action again.

“Hmmm… well maybe we can take advantage of that...” He hugged Sweetie and slowly sat the two of them up. “Why don’t you turn around and lie down on your front...”

Sweetie looked confused but did as instructed.

“Thanks, now if I just get behind you… and… mmmm… yeah!” Spike growled as he grabbed his beloved’s plush flank and slowly entered her again. “And now...”

Sweetie bit her lip as she felt the tape being ripped off, followed by her blaster cannons springing out of their compartments on her back like a pair of jack-in-the-boxes.

“I can use these as grips!” Spike said triumphantly as he grabbed the weapons’ mountings and began to pound his mare again. Sweetie bit down harder as she felt some small slivers of painful feedback dig their way through her circuits, before the pleasurable sensations returned. Silently she paid Spike due praise for his clever thinking, realising that in this position both of their extra parts were out of the way.

“Yeah… ngh… Celestia this is good.” Spike moaned as his pelvis rammed Sweetie’s flank harder.

“S-So good… ahhhh… you’re so deep in me, Spike… ngh… please… d-don’t pull out. Ahhh… cum in me! Grrr… fill me up… I want everything you’ve got!” She begged. She could feel a second orgasm building as the ridges of Spike’s penis dragged to and fro across her sensitive depths. Her walls convulsed around his knot, ensuring he’d stay right where she wanted him. They’d crossed the threshold, and now they were both going to join each other in going all the way to the end.

Spike wordlessly confirmed he’d do as asked by picking up his pace again. Now that he didn’t need to worry about his wings, or tail, or getting shot by Sweetie’s blasters, he could focus all his energy on bringing things to an explosive ending. Even if he still had no idea about what might follow, he was going to respect his marefriend’s wishes! Especially when she was making it so damn satisfying for him, with the tightness and the whimpering, and the pleasurable winks as he thrust and pounded till at last he felt his entire body seize up in unimaginably sweet release.

“AHHHH YEAH, SPIKE!” Sweetie screamed as she felt a rush of searing hot seed flood her womb. Again, her CPU hit critical capacity as an overload of pleasurable feedback was fed into it, making her join her dragon in crying and thrashing in the throes of a final peak. Her body lights heralded the union by shining bright as stars all throughout the unicorn’s climax.

As he shot a generous amount of his cum into his mare, Spike let himself slowly wilt, collapsing onto the bed beside her and holding Sweetie tightly as she likewise came down off her orgasmic high. Silence finally fell upon the bedroom as the two lay still, their breathing barely a whisper as they let the afterglow bond their souls together like the sex had their bodies.

“Spike… heh… thank you.” Sweetie whimpered, letting a few joyful tears run down her cheeks as Spike stripped the tape off her barrell.

“No, thank you, Sweetie. For giving me a chance, letting me show that I truly love you for who you are, my beautiful, kind, and wonderful robot mare.” He replied, kissing her again as she turned and wrapped her forelegs around her neck. “So… feeling ready for the party tomorrow? To show the world how happy we are to be a couple?”

Sweetie’s eyes whirred and dilated as she thought it over, leading her to let out an embarrassed giggle.

“Maybe if we did it again? Just to be sure?” She asked. “I mean so long as we’re not stopping for anything… and now I know I can keep myself from shooting up the room...”

Spike chuckled and nuzzled the unicorn.

“I think I’m up for a few more rounds. Just how about this time we try a few other positions?”

***

In her own room, Twilight lay on her bed, amidst her long forgotten pile of books. Her eyes remained fixed on the ceiling as all around her she felt the crystal walls shake ever so slightly with the sounds and the action taking place in Spike’s room just down the hall.

“Note for tomorrow: contact the Ponyville press and ask that my ad be put back into their lonely hearts column.” She muttered to herself. “I have got to start dating again!”

Author's Note

So after some thought and reading through the comments to chapter 7, I decided this had to happen. Wanted to give non-anthro pony clop a try, and after debating where I wanted the series to go next it seemed like Spike and Sweetie needed to become sexually active.

I tried to make this half-arousing, half-realistic for their first time (since, let's face it, no one is automatically great at sex from the get go) show that while this is a major stride in their relationship they've still got a lot more ground to cover if they want to be as perfect a couple as possible, and that's before they find out what other complications are looming on the horizon.

Yes, while we're now at the point I'm sure many were waiting for, this series isn't done yet. I'm going to explore a bit more about about Sweetie's possible origins and of course if indeed she and Spike are ever going to become parents. Also contemplating a few other pairings for their friends, hence the ending tidbit with Twilight deciding she might try finding somepony for herself.

Again, I'm open to suggestions on who you think she should end up with.
