“Looking good, Spike. Looking real good.” He admired his shirtless form in the mirror. There was a lot more to look at now compared to when he’d first started this little confidence building ritual back when he was a scrawny thirteen-year-old. He’d filled out and bulked up quite a bit. He wasn’t broad shouldered and super muscular like Big Mac but had a lithe, toned body like an athletic pegasus. He didn’t have to put in nearly the same amount effort for it, though. It was a side effect of his draconic nature.

He supposed he had been quite lucky so far. Aside from having vertical slit pupils, pointed ears, and the ability to breathe a little fire, he looked the same as an Earth Equestrian. When he’d attended the dragon flight, the older dragons he’d seen were massive, too big to fit through doors in Ponyville. Even most of the teenage dragons from that flight would tower over most Equestrians. Spike had reached that age himself and not had the same size, but there was no telling how he would change going forward.

He’d grown about two feet since he’d arrived in Ponyville, making him four inches taller than Twilight. Equestrians generally stopped growing when they reached his age, but no one in Equestria knew enough about dragons to say if that would hold for him. It seemed possible all dragons just kept growing throughout their entire lives. Still, most dragons had wings or horns too, unlike Spike. There were many different kinds of dragons and there was no way to tell what that meant for his future growth. Equestria was his home and he worried about what would happen if he began to look less and less like the Equestrians around him.

He’d been looking at himself in various poses for about ten minutes. He was intentionally stretching things out. When Star had explained that Twilight would be delaying today’s research, Spike wasn’t sure what to do with the extra time. He’d done some basic workouts in his room, pushups, sit-ups and the like, then read through his newest comics before heading to his special mirror room to boost his confidence a bit. He wished Twilight had rescheduled earlier on so he’d have been able to form some solid plans. He needed to make sure his idle time was filled. When he wasn’t keeping himself busy, he was making it more likely that bad thoughts would bubble up.

As he raised his arms and showed off his biceps to the mirror, the door swung open. Starlight stared at him with a puzzled look on her face. He blushed and waved before quickly throwing his T-shirt back on. “H-hey Starlight. Are you lost again?”

“A little, it seems.” She smiled apologetically. “I was looking for you, but I thought this was your bedroom.”

“It’s one more door over. Is Twilight ready to start the research?”

“Not yet. Actually, I was coming to let you know Twilight and I need more time. We have something important we’re talking about and it may take a bit to iron out.”

“Is this about you meeting Sunburst in the Crystal Empire?”

Starlight paused, the muscles in her temples tensing up as she eyed Spike. “How did you know about that?”

“Twilight told me.” He tilted his head in confusion. It wasn’t like the friendship lessons were a secret. “She was so excited about your first lesson she probably told everyone about it.”

He’d expected an embarrassed smile, but Starlight gave a grim frown instead, like everyone knowing about her upcoming meeting with Sunburst was a burden. He moved forward and put a hand on her shoulder. “Starlight, what’s wrong?”

She slowly pulled back her frown. “Well, I guess you could say I’m not exactly thrilled with meeting up with Sunburst again. It’s been years since I saw him and when he left town to train in magic school....”

“You blamed cutie marks and stripped a whole village of theirs and when Twilight and the other stopped you, you went back in time and almost destroyed Equestria,” Spike said with a nod.

“I was going to say things were complicated between us. But right, time travel and all that too.” Starlight nodded. “But, that isn’t what Twilight and I are talking about. It’s something else that’s very important. Once we’re done talking, we’d both like to tell you about it.”

“Uh, okay, I guess,” Spike said uncertainly. It was strange for Twilight to send Star to arrange talks and stranger to need to wait for secret conversations to finish before he was told about something important.

“Great.” Starlight grinned. “Meet us in the main dining room for dinner. We’ll handle all the cooking tonight, so don’t worry about the kitchen Sound good?”

“S-sure.”

“Alright, I’ll see you then!” Star turned and started walking back down the hall at a brisk pace like she was resisting the urge to sprint. She and Twilight were both acting weird today. It usually took a threat to Ponyville to get Twilight to skip time in the library, and now he’d been told she needed to delay twice in the same day. It was odder still that they didn’t want him to do any of the cooking. It was starting to sound like there was going to be a surprise party waiting for him in the dining room, but he wasn't sure what the occasion would be. If this was instigated by Pinkie Pie the occasion could be a three-days-till-crystalling party. There was no way to tell what was going on until dinner.

Waiting until dinner time meant another two hours, which was going to take some effort to fill. He didn’t want to do any more exercise. He was worried too much would accelerate his growth. He did have one more unread comic. He’d planned to read it tomorrow but he could move the schedule forward in a pinch.

He returned to his bedroom and fished out the extra comic, reading it through. Then he went back and reread the earlier day’s comics, taking a closer look at the panels for any clues he might have missed. After he was done with the second read-through he opened up his role playing kit and did some planning for his next game of Ogres and Oubliettes. Things were really heating up in Spiketopia and he needed to set up a great adventure for the next guy’s night.

Eventually, he had most of the next adventure planned out and set his rulebooks aside. There was another twenty minutes before the usual dinner time. It was a frustrating amount of time to fill. He could try reorganizing his comic collection which might take half an hour, or practice compliments to give to Rarity, which would likely not take more than five minutes.

He wondered if Twilight and Star were finishing up with whatever mysterious conversation they were having. They both had been acting strange the last week. It had started with Twilight wearing some skimpy outfits. Later she and Star would pass weird glances at each other when they thought Spike wasn’t looking, or even when one wasn’t looking at the other. They had spent more and more time together, far more than just discussions of friendship could justify. A lot of that time seemed to be hanging out together in each other’s bedrooms.

A bedroom wasn’t the sort of place for friendly chatter, more like…

Spike shuddered in arousal. He’d done it again. He felt a tingle like electricity arc up his back. A warm ache sprung up in his loins and his cock started to perk up. He’d let his mind wander and got those bad thoughts back into his head. It was getting stronger too, as he imagined Star pressing Twilight up against a wall and kissing her, tugging down Twilight's skirt. His hips tingled with the urge to buck forward.

He had to stop this before things got out of hand. He dashed over to his shower, stripping off his clothes as he went. Once he was inside the tub and drew the curtain, he turned on the cold water full blast.

He gasped as the wave of cold water hit him. He fought the urge to curl up in a ball, instead moving around and making sure the water covered his whole body. He waited as it cooled his body down, including his hard on. After five minutes he was limp again, his body too shocked by the temperature to think about sex. It wasn’t very pleasant, but the cold showers had been the most effective way to hold back his dragon lust.

He still remembered the shock from finding the book on dragons in Twilight’s library. He'd been sure he'd scoured the library and found nothing the previous year, but then there it had been plain as day on the shelf. He’d read it in secret after their daily crystalling research. It had covered topics like dragon greed he was all too familiar with, but also explained dragon lust.

It made perfect sense. Dragons tended to be solitary creatures and saw other dragons as competition. As a result, they needed strong biological compulsions to reproduce. Once a dragon reached maturity, they would have a growing lust, becoming more easily turned on and more likely to fantasize about sex. At first, a dragon could just masturbate, but doing so would actually make the dragon lust even stronger. The more a dragon gave into the lust, the more intense it would get until there was an overpowering compulsion to find a mate and get the real thing. The book explained that dragons that gave into the lust without finding a mate would eventually become obsessed and would only be able to think about sex.

Once they did sleep with another dragon, the lust transformed to make sure they would stay around to raise offspring. A dragon would become completely devoted to their mate, following their needs and instructions above all else.

Spike liked the idea of being devoted to Rarity, but that would have to come naturally. In the meantime, his lust was dangerous. If he gave into his lust, he would eventually lose control and become obsessed with sleeping with the first woman he could find. The book had described dragon courtship as...aggressive.

He’d lost control of his greed once and nearly destroyed Ponyville. He could never allow himself to lose control and hurt his friends again. There was only one way to stop it. The book had explained in detail. He couldn't give into his lust at all. He would have to keep it in constant control. It was a small price to pay to safeguard Rarity and the others, though. Spike hadn’t masturbated since.

It hadn’t been a moment too soon. He’d found the book the same day he’d started fantasizing about Twilight and Star. It had come unbidden earlier that day during breakfast. It wasn’t shocking he would have thoughts about Star now and then. As scared as he’d been of her before meeting her, she was quite attractive. Twilight though...he’d never thought about Twilight sexually before. She was like a sister to him. The explanation was obvious. He’d been indulging himself on nearly a daily basis since he’d come of age and the dragon lust had started to get to him.

The first few days had been difficult, but Spike had adjusted to his celibacy. He got aroused far more easily and had ended up with a tent in his pants on some embarrassing occasions. Once he’d even been in Pinkie Pie’s house and she’d asked about Twilight and Star. That had started making him fantasize about them and he’d had to beat a quick retreat. He’d been taking a lot of cold showers recently. The celibacy had at least been effective at preventing his lust from getting any worse. He still had fantasies about Star and Twilight, but it had not progressed any further.

Spike was back in control of himself after the shower. He quickly toweled off and redressed. He realized the shower had managed to fill the twenty minutes he’d been lingering on, so headed over to the main dining room. When it was just the three of them, they usually ate dinner in one of the smaller dining areas. The main dining room was big enough to seat at least eight people and was usually for when Twilight’s friends were over.

Spike walked through the double doors and found Starlight sitting alone at the golden round table. There was only one other chair at the table, set up to the right of Star. There were only two place settings as well, with utensils in front of the Star and the empty chair. The only other thing on the table was a small brass bell with a wooden handle. Star stood up and pulled out the second chair. “Ah, you made it. Wonderful.”

“Well, you asked me to come.” Everything seemed strange. Obviously, this was no surprise party, but there should at least be three seats ready. “Where’s Twilight?”

“She’s getting us our first course. She did the cooking tonight. Also, I wanted to talk to you a bit in private before she came in.”

Spike frowned, but took the offered seat, settling down into the purple cushion. He eyed Star curiously as she sat back down next to him. “What exactly is this about Star?”

“Well you see, Spike, that talk I was having with Twilight had to do with some desires she has. She’s made a big discovery.”

“Discovery?” Spike said with increasing confusion.

“Yes. You see, she’s a very deep submissive.”

“Twilight, submissive?” Spike looked askance at Star. “We’re talking about the same Twilight that faced down Tirek, right?”

“Oh that’s not quite how being submissive works,“ Star giggled, “Twilight is very brave and assertive when she needs to be, but in her heart, she is looking for a person- the right person- to give up control to. It’s been a slow journey for her that I’ve helped her with. Just recently she’s asked me to take full control of her.”

“What does that even mean?” Spike’s head was swimming. He tried to imagine Twilight, the obsessive scheduler and list maker ever giving up control to someone else and it didn’t make sense. But Starlight was explaining it so matter of factly.

“It means Twilight doesn’t want to make decisions anymore. She trusts me deeply enough that she wants to be my slave, and I’ve humbly accepted.”

Star reached for the bell on the table and gave it a ring as the word slave rattled around Spike’s head. He was going to protest and ask how Twilight could ever want something like that, but in response to the bell, Twilight emerged from the kitchen door and left Spike speechless.

“Appetizers are ready, Miss Starlight.” Twilight chirped happily.

The first thing Spike noticed was her makeup. Outside of formal occasions, Spike had never seen Twilight with more than some faint pink lip gloss. Even on those formal occasions, her look would always be subtle and understated. Now her makeup was explicit and immaculate. She had applied a dark purple lipstick, carefully lined to make a perfect border between her lips and pale skin. She’d applied a matching smokey purple eyeshadow brought into sharp contrast with black eyeliner and curled eyelashes, darkened with mascara. The dark colors were offset with the lightest application of blush.

Even more surprising was her outfit. Twilight was dressed in some twisted version of a maid uniform. She had a white lace headpiece with bits of violet ribbon twisted through, matching her hair. Her top was cut low and off the shoulder, forming a straight line of frilly lace across her arms and chest with the barest hint of cleavage. The top cut off an inch above her navel, exposing her tummy.

Her skirt hugged tightly against her hips with a tiny white apron and two ruffled layers that collectively went down to her upper thighs. There was another narrow band of exposed skin followed by white stockings that began just above her knees, topped with violet ribbon like the headpiece. Spike’s eyes trailed down Twilight’s legs until they reached her pair of black high heels.

Most shocking was the silver collar on her neck. In the center of the collar, there was a purple sapphire cut to look just like Twilight’s cutie mark.

Spike could only gawk, trying to process the radical change in Twilight’s look. He felt a tingle between his legs. “Do you like the outfit?” Starlight cut in. “I had it custom ordered just for her. Rarity always does such stunning work, especially on the collar. I suspect she prepares gems that resemble her friend’s cutie marks for such projects.”

Twilight was holding a small covered platter in each hand, held off to her sides. They were the last thing Spike noticed. She began to walk over to the table, hips swaying back and forth with each step. Every couple steps she paused with a slight wobble, still not 100% sure-footed in the heels. She moved to Spike first and set a tray in front of him, pulling the top off to reveal a bowl of New Equine clam chowder soup. Spike stared dumbly at her. “T-Twilight?”

“Your appetizer is served, Spike.” She gave him a mischievous grin and trailed her fingers along his shoulder while she made her way to Star, setting down the second platter. Once she’d taken off the top of the second tray, she stood at Star’s side, hands clasped together in front of her, waiting patiently.

Star looked over at Spike, seeming to notice he was still speechless. “This is what I meant Spike.” She idly wrapped an arm around Twilight’s hips and stroked her thigh as she spoke. Twilight rolled her hips and pressed into the touch in response. “This is who Twilight wants to be. She wants to be a controlled, obedient Twi-slave. Isn’t that right?”

“Yes, Miss Starlight,” Twilight replied with a broad smile. “My deepest bliss is to serve you. Is there anything else you need?”

“Oh yes, Twi. I seem to have dropped my fork.” Star picked a fork up from the table and tossed it behind her. “Would you be a dear and go pick it up for me?”

Twilight shivered happily. “Ohh, of course, Mistress.” She replied with a husky tone. She turned and walked over to the fork, back facing Starlight and Spike. She bent down from the hip to pick it up. Her tiny skirt rode up, revealing to Spike that her uniform didn’t include panties. He gasped as Twilight lingered in her pose, putting her bare pussy on full display. His cock began to stir as he processed what he was seeing.

Twilight finally rose and walked back to Star, placing the fork down. Star ran a finger along Twilight’s tummy and smiled. “Mmm, very good girl.” Star patted her lap invitingly and Twilight quickly slid into place, wrapping her arm around Star’s shoulder. Starlight tried her first spoonful of soup. “Mmmm, this is so delicious. You did very well Twi.”

Twilight wiggled closer into Star’s lap. “I’m so glad I pleased you, Mistress.”

Star dipped one finger into her soup and offered it to Twilight. “You deserve to get a taste of your handiwork as well.” Twilight eagerly wrapped her lips around the finger and began to slowly suckle. Her eyes slid shut and she cooed, seeming totally focused on the finger.

Spike grunted as the sight hit him with a new wave of arousal. His cock was pressing uncomfortably against his jeans. He tried his best to shift it flat while staring at Star and Twilight. He wanted to run and take another cold shower. He wanted to leap over and tear Twilight away and demand to know what was wrong with her. Instead, no matter what he knew he should be doing, he seemed paralyzed and only able to watch as Star toyed with Twilight. He’d been trapped in his chair ever since Twilight had come in dressed like that. Was it the dragon lust?

The grunt had apparently gotten Star's attention. “Oh Spike, is everything okay? You seem flushed. Maybe seeing Twilight like this has you a bit worked up. Twi, please go check on poor Spike.”

“Of course Mistress.” Twilight hopped out of Star’s lap and made her way over to Spike. She pushed his chair back away from the table and knelt in front of him. That mischievous smile came back as she reached out and gripped his jeans. Spike shivered, too aroused to do anything. She used her magic to unzip his jeans and slowly tugged them down along with his underwear. His cock stood up at full attention inches from Twilight’s face. “Oh, wow.”

“My my. Spike is more pent up than I imagined.” Starlight said with a purr, walking behind his seat to get a better view. “He seems to be in a lot of discomfort. Tell me, pet, have you ever given a boy a blowjob before?”

“No Mistress, never. I’ve..read about how it’s done though.” She replied, blushing slightly. “It was when I was dating Flash, but we never got that far.”

Starlight giggled in response. “You do love your research. Let’s see if that reading paid off. Help Spike relieve that tension.”

“Yes Miss Starlight.” Twilight fluttered her eyes and purred like she was savoring a bit of chocolate cake. She looked up reassuringly into Spike’s eyes. “Just relax, Spike.” She leaned in and gave the tip of his cock a soft kiss, then licked slowly down to the base of his shaft and all the way back up. Once she returned there, she wrapped her lips around his head and began to slowly inch him deeper into her mouth.

Spike moaned helplessly, all his thoughts melting under the warm sensation of her lips and tongue. It felt better than he could have ever dreamed. His body shuddered and twitched as she pushed deeper and deeper. Her lips finally made contact with the base of his cock. “Ohhh god. Twilight I…” He grasped for something more to say, but only expletives came to mind.

Once she’d adjusted to Spike’s whole length, she began to slowly slide up and down his shaft. Spike’s breath grew ragged, interspersed with moans and other noises of pleasure. Twilight reached down and tentatively cupped his balls with one hand. Spike gasped and involuntarily bucked his hips forward. Twilight let out a muffled grunt in surprise as he shoved his cock into her, but didn’t let it slow down her pace.

The sensations grew more and more intense, but the week’s chastity had increased his staying power like his cock had forgotten how to cum and was trying to get back up to speed. Still, that moment grew steadily. “Oh fuck Twilight I….”

“Shhh.” Starlight’s hands rested on Spike’s shoulders and slowly rubbed them. “Just relax Spike. Let Twi do all the work for you. You’ve always been a good assistant for her. Let her assist you this time.”

The soft massage and Star’s words made his body melt limp in the chair, simply staring as Twilight worked on her task. She continued bobbing up and down, increasing her pace as he grew closer and closer. It felt like an eternity, but Spike finally was on the edge. He tried to warn Twilight but all he could manage to say was “I...I’m…”

His body tensed and he partially sat up in his seat as his cock pulsed, shooting into Twilight’s mouth. His mind blanked out, focused totally on the pleasure. His cock twitched again and again, but Twilight kept her lips wrapped around him, containing every spurt of cum. Finally, he slumped back into the chair, gasping for breath.

Twilight slowly pulled back, releasing his cock with a soft pop. The brief opening of her lips allowed a tiny stream of cum to dribble down her chin. She closed her eyes and paused for a moment, seeming to savor the knowledge of what she’d just done. The sides of her throat tensed up as she swallowed. Her eyes opened up again and she extended her tongue down as far as it could go and lapped up the final strand of Spike’s seed before staring at Starlight with a hopeful look.

“Very well done, Twi. You even swallowed.” Starlight commented with a tone of surprise.

“The book said boys like it when you do that, Mistress.”

“Such a naughty girl. How does Spike taste?”

“It’s sweet but with a kind of bitter and metallic aftertaste.”

Starlight giggled. “Oh, that’s very descriptive. You seem to have a very refined palate for cum.”

Twilight blushed deeply. “It’s the first I’ve ever tasted it, Mistress, and I wanted to give the best description of it I could.”

Spike could barely keep track of the words. He tried to catch his breath but seemed to just get more and more worked up. His cock was still just as hard as before, now with a circle of purple at the base from Twilight’s lips. The only thought in his mind that could last more than a few seconds was how much he needed to fuck Twilight. Getting a blowjob from her had driven his lust overboard. He could feel the compulsion to mate, to mount a female. All those thoughts were focused on Twilight now. There was no fighting back. Every inch of his body screamed that he needed to be inside her.

He couldn’t fight it but didn’t want to lose complete control. If she would do it willingly... “Twilight. I...please...I need you.” He stuttered plaintively. “I need you so much I..” He hoped she would say yes. He was desperate. It would happen one way or another. He would mate with her, become devoted to her. Would he lose his feelings for Rarity? It was possible, but there was no controlling the dragon lust. “I need to fuck you.”

“Why are you asking her?” Starlight said with a firm tone. Spike looked back at her in confusion. “I told you earlier Spike, Twilight is just a slave now. She doesn’t make decisions like that anymore. She’s my property. If you want to fuck Twilight, the person you need to beg is me.”

He stared dumbly at Starlight as the meaning of her words tumbled into his mind. The logic of it didn’t matter. All that mattered was saying or doing whatever would allow him to mate with Twilight. “Please Star. I need to fuck Twilight. Please let me.”

“As long as you understand that Twilight is just an extension of my will.”

“Yes, yes anything!” He said. He couldn’t think much about it, but something in the back of his mind seemed to click, like a lock snapping shut. Twilight belonged to Star. Star decided who she slept with, so if he had sex with Twilight, it was effectively having sex with Star.

“Well, because you asked so nicely, I suppose I can give you Twilight for now. Twi-slave, hop up in Spike’s lap and ride his cock.”

“Yes, Mistress.” Twilight purred. She licked her lips as she slid up to her feet and unzipped her skirt, letting it flutter to the floor.

“You’ll be giving Spike your virginity, won’t you Twi-slave?” Starlight asked with a grin.

“Noooo Mistress. My virginity doesn't belong to me.” Twilight moaned in pleasure as she spoke. “You’re giving it to Spike, it’s not mine to give.” She straddled Spike’s lap, and slowly worked her hips into place. She reached down, making sure Spike's cock was lined up, then looked deep into his eyes as she eased her hips down.

Both of them gasped and shuddered with the new sensation. Spike remained motionless, completely lost in the pleasure, but Twilight knew she has a task to obey. She regained her composure from the initial rush of putting Spike inside her and began to buck her hips, slow and irregular at first, but soon finding a steady rhythm. “Am I doing it right, Mistress?”

“You’re doing great, Twi. Try rolling your hips a bit for him.”

Spike reached out and gripped Twilight’s ass, moaning as she milked his cock. There was nothing but the dragon lust now. He was where he was supposed to be, inside a female. He was fucking Twilight but he was mating with Star. He would be devoted to Starlight. He would love and obey her. It was how things were meant to be. The dragon lust would always win in the end.

He could feel himself building again, reaching that moment where he would cum and change forever. He kept his eyes focused on Twilight’s. They both began to pant, building together, connected in the most intimate way they could.

“Good boy Spike. When you cum, you’ll feel it as the dragon lust overpowers your mind, shifting into deep devotion.” He realized vaguely it was Starlight speaking, but it didn’t matter. He began to buck his hips, pushing back into Twilight. Finally, he tumbled over the edge, bursting deep inside of Twilight as she moaned and tensed in her own climax. He could tell nothing would ever be the same for him. It would be better. He had embraced his true dragon nature and nothing had ever felt so good.

Author's Note

And yet another chapter, and one slightly off the usual road. Most chapters are female focused, but the guys get love now and then too. This chapter took a lot more time as I wanted to make sure I was landing an appropriate tone in certain sections. But with the delay, there is a bonus!

You probably have noticed that the cover image for the story has changed. I commissioned the excellent artist Light to make cover art specifically for OiM. The image has been slightly cropped and resized for the site, but links to the full version will be in the story description. That will be edited next. I'm going to add a little more nuance to the story description so it says more than just the short tag.

This chapter always required me to do a little square circling on dragons in a human-ified Equestria. My basic headcanon for this is that as 'dragons' age, they don't get as big as buildings, but end up getting to ten to twelve feet tall and looking more and more like characters from Jojo's Bizarre Adventure or Fist of the North Star. Spike isn't so far along as that, of course, and as described could still be mistaken for a regular Equestrian at close distance.

This chapter represents an informal End of Part 1. But we have many more parts to go. Everyone's going to be heading to the Crystal Empire soon for Flurry Heart's crystalling. Starlight will be on the prowl for new victims and may also run into Sunburst. Perhaps we'll learn how much of what she convinced Twilight and Spike about her past was true and what was a lie. Things will only accelerate from here.
