Over the next few days, Spike avoided going down into the underground caverns for a while, wanting to take a break from those damned bats. He didn't want to risk running into another one of those stronger bats, not until he'd grown in strength. Thus, he spent his time on the surface, practicing his fighting skills against imps and goblins, honing his skills and gathering what he could from them. He tossed out the ale that those annoying goblin girls dropped, not being one for drinking anyway, and he hesitantly held on to some of the items he'd gotten off of the imps, wondering if they had any use aside from corrupting him. A part of him was tempted to drink some more of that milk, since had been so tasty before... but he fought off the urge, not wanting to lose himself.

Eventually, he began to feel himself growing stronger, faster. His fighting skills improved gradually, to the point where he felt confident enough to travel down once again. And so he made his way, ready for whatever got in his way.

The first few hours of walking were relatively uneventful, with no sign of any opposition in his way. He even managed to find another fire ruby, as he'd decided to dub it, embedded in the rocks. It looked awfully tasty, yet he wasn't ready to try and eat it, not yet. He'd save them both for now.

Just when things seemed peaceful at last, a small group of bat gremlins attacked, shrieking and cackling as they tried to capture him once more. Spike took them out easily with his newly developed reflexes and brute strength, and soon he was walking away from five groaning bat gremlins. He had been keeping his lust in check by masturbating regularly, and while he didn't like having to stoop to such a level, it was better than ending up fucking with bats. He shuddered as the thought of all those naked bodies ran through his head, and as he walked on, he felt the heat rise in his crotch.

"Again? Celestia damn it, I just jerked off before I went down here..." he complained to himself as he shook his head in frustration. The last thing he needed was to fuck right now.

He had to take action. He had one thing in mind: stop these damned bats from coming after him. He wanted to find out where these bats were coming from, confront their leader, and get them off his tail. He had to get the message across that he wasn't on the menu. He wouldn't let himself become a breeder for them, he wouldn't let them wear him down. He was Spike the Dragon, and he was going to get out, one way or another.

A few more small encounters with more bats later, and Spike once again found himself face to face with a stronger variant. She looked at him lustfully, but he immediately evaded eye contact, closing off his eyes to try and judge where she was by sound alone.

"Hmph. Pesky little lover. You zink yourself a bat? Ha! You are a fool! Stop all zis fighting, and come to me~!"

He could hear her taking steps forward, and with a roar he charged forward, thrusting all of his weight... only for her to leap up and out of the way with a rich laugh. He stumbled and fell hard to the ground as he heard her gently land a distance away. She was taunting him.

"You'll 'ave to try 'arder zen zat, my lover~! Don't deny me~."

He struggled to rise, then turned to face her with his eyes screwed shut. He couldn't give in. Not now. As he listened to her slowly walk towards him, his mind raced. What did he know about them? There had to be some plan to take her out quickly...

"Come now, isn't this romantic? Just me and you, alone in the dark, my little lover~..."

That sparked something. An idea. Dark... It was always dark down here. The bats never left the darkness! That was it! He slowly began to collect his breath, and just before she reached him, he let it out, a large ball of bright flame, right in her face. She shrieked in pain, clawing at her eyes as she doubled over. Spike took his chance and slammed his body into hers, knocking her out. He'd won... he'd overcome one of their strongest fighters! He bent down to retrieve the spoils of war that he'd come accustomed to finding, a few coins and... a vial of blood? That's what it looked like, a small vial of blood.

With a shrug, he decided to pocket it... only to find he apparently had run out of space. One pocket had two fire rubies, another had three vials of that milk, and yet another had a single draft of some strange off-white liquid. In the back of his mind, only three options presented themselves: toss out the vial, dump out a pocket to make room, or drink it. For some reason the idea of taking something out of a pocket and using it immediately to make room didn't occur to him. Instead, he looked at the vial closely. From what he understood, eating and drinking these things had a bad tendency of changing him. Still, he couldn't help but admit he was curious and didn't want it to go to waste... thus, in a brief moment of curiosity, he uncorked it and chugged it down.

Immediately, he felt a warm rush over take his body as his muscles locked up. His back burned, his teeth hurt, and his chest felt as if it were swollen. When he finally recovered, he immediately did a check to see what had changed. He instantly felt a strange new weight on his back, and when he turned to check... wings. He had wings. Not big enough to fly with just yet, but... he had wings. This... was something he was actually happy about for once! He grinned... only to realize his fangs had grown longer again. He let out another sigh as he crossed his arms... finding the final gift the vial had given him.

He had boobs. Not big ones. But... boobs. He stared down at them in one part disgust, one part fear, two parts lust, and three parts awe. Honestly, his breasts looked about the size of the usual bat gremlins, not quite as big and firm and sexy as the stronger one, like the one sitting right in front of him, staring at him expectantly. Wait...

Spike snapped out of his haze to face her. She wasn't trying to escape, and he didn't feel his mind clouding over from looking at her. She looked... not scared, not sad but... it was hard to put a name on how she looked. Seeing that Spike was paying attention to her though, she gave him a weak smile.

"Vhat do you vish of me, master? I vish to serve you."

Spike... wasn't sure how to respond to that. Then he remembered what he came here for. "I want you to take me to your leader!" he said in his most intimidating voice... which wasn't as intimidating as he'd thought it would be, since his tone had apparently grown more feminine. He would... panic over that later. Right now, he had business.

The bat nodded eagerly as she rose, shaking slightly, to lead him down the tunnels. On and on they walked, silently, nothing disturbing them on their trip. Finally, after what seemed like hours of walking, they reached a large city of stone in an particularly big cavern. The moment they arrived, every bat stopped what they were doing and turned to stare at him with glowing eyes and wide grins.

"It's the dragon!"
"Look at that stud!"
"I call first fucks!"
"No I saw him first!"
"Take him for the Queen!"

Every single one of them took flight and began to swarm around him in one big, screeching tornado of bats. He... hadn't been prepared for this. He hadn't expected them all to come at him at once. He stood his ground and tried to swipe them away when ever one lunged, but there were just too many of them. There were hundreds of bat gremlins spiraling around him, all laughing at him and taunting him at once, and it was only a matter of time before they broke him down. He needed something to give him a boost. Something that would fend them off... He didn't think he could muster a flame big enough to scare them off though...

It was then that he remembered something. The fire rubies! He reached into his pocket, stuffing one and then the other into his mouth, dodging bats all the while. He felt his inner flame burning even brighter, and as he built up his power, he felt stronger than he'd ever had before. With one massive roar, he let up a colossal plume of fire straight up through the middle of the bat tornado, so massive that it reached the cave ceiling. He kept it going even as the fell blinded to the ground, letting it rip until his throat was raw. He fell to the ground panting, a tired smile on his face. The bats were all down. He had done it. He had done it...

His thoughts of victory were interrupted by a slow, deliberate clap. He looked up to find... the most curvaceous bat he'd ever seen. She was tall, possibly taller than him, with plentiful round curves and a large, buxom chest. Her massive wings draped around her back like a cape, and she wore a revealing set of black, chitinous armor. Atop her head rested a crown that looked like it had been carved out of obsidian. She was staring down at him with a look that seemed to be a mixture of admiration, lust, and defiance.

"A good show to be sure, noble dragon. You've bested my daughters in every way, it seems. To what do I owe this pleasure? Have you come to do the demon's work and slay us all? Why do you try and destroy everything we've worked for for so long?" Her voice was rich and melodic, with a somewhat dominant quality to it.

Spike rose and stared back at her defiantly. "I didn't mean to cause any trouble. But I had to come to make you stop attacking me. I don't want to be your enemy. But I also do not want to be a mindless breeder for your people. I have my own fight, and I cannot let myself be taken by anyone. Tell your daughters to stop trying to kidnap me, have your people stop trying to force me into servitude, and I will leave you alone. We don't have to fight."

A moment passed as the Bat Queen seemed to consider his words. "Well then. I think we can come to some sort of agreement. It seems we have a common goal, and I see now that you would serve us better as an ally than a slave. However, I have one condition. Meet it, and I will not only command my daughters to cease attacking you, but I will give you full access to our city's services."

"What do you want?" Spike asked suspiciously. Her offer did sound good, but he had to be sure he knew what he was getting into. In the back of his head, he knew that he would agree to this to end the frustration of dealing with her army.

She grinned to him. "You are far too good to simply be a breeder for my daughters. Mate with me instead, right now, and I shall make my decree. Give me your seed so that we can create a new, stronger breed of gremlin! It will only be once, that shall be enough. Do we have a deal, sir dragon?" She stood tall in a regal post, accentuating her magnificent queenly curves. Spike had to admit, she was the most beautiful creature he'd seen in this place.

Spike began to quickly weigh his options. On the one hand, this was completely consenting sex, both would be in agreement and he would be in his right mind. Plus it would get all of those bats off of his back. On the other hand, he didn't like the idea of having sex like this, not without any love between them. Besides, she was way above his league. It quickly became apparent to him that despite any of his doubts, it was unquestionably better to go through with it.

"Alright. You have a deal," Spike said as he stepped forward. Her grin widened, and he could tell that it was from genuine joy, devoid of malicious intent. He followed as she led him on to her palace in the center of the city, a massive towering place that seemed to have been expertly carved. She led him on to her private suite, and had him wait outside her door to 'freshen up' as she put it. As he sat there, he looked up and gaze into a mirror in the hall. He noticed he'd gone through yet another round of changes thanks to the two fire rubies he'd eaten.

His body seemed... simultaneously more masculine and more feminine. His muscles were developing again, yet his form seemed to be slimming into a more feminine hourglass. His hips had swollen larger and his eyes... the whites of them had turned a pale yellow, while his irises were now as red as those rubies. Plus... he felt his inner fire magic burning even hotter than usual. It felt... good. Really good. He didn't want to admit it to himself, but he liked these changes. He liked the rush of power they gave him. Deep down, he wouldn't mind trying more of those rubies... heck, a part of him even began to grow more accustomed to changes in general. He could use these to his advantage. He could get stronger faster. He could-

"I'm ready for you, my noble dragon warrior~," the Bat Queen called from her room, snapping Spike out of his thoughts. He rose to enter, only to freeze in awe at the sight of her. She was wearing a light, see-through silk dress, her wings folded tightly to her back as she laid on a massive bed, fit for a queen of course. She laid on her side with a magnificent come-hither smile, her bountiful breasts on full display as she teasingly rubbed her hips together. "Come to me. Take me and claim your prize for defeating my army, you big, mighty beast you~."

She seemed to want to roleplay with him, and in his lustful state, he felt inclined to play along. "Oh, I intend to, my beautiful queen. I fought long and hard, just to claim you as my own~." He let out a low growl as he stepped forward, slipping out of his clothes, at which she clucked her tongue in disapproval.

"Defeating my entire army while wearing naught but filthy rags? Oh, that does not suit one such as yourself. I'll have to see about getting you a more suiting set of armor. But there is time for that later. Now is the time for you to take me and make me yours~... do whatever you want with me~..."

Spike grinned wide as he climbed up onto the bed with her, eying her sensuous form lustfully. He did want to take her right here, right now. She was beautiful, magnificent, and just down right sexy in every sense of the word. Now that he was closer, he could see that she was a bit more aged then he thought, but that was alright. He'd always had a thing for older women, and she was looking good for her age.

"Let's get a better look at my prize... will you remove your clothes, or shall I do it for you~?" He bared his claws, and at the excited look she gave him, he knew he had her permission to rip into it. He tore away the expensive looking garb as she let out a squeal of mock terror.

"Oh no, you dreadful rogue, that was my favorite nightgown! Oh dear, now my royal assets are completely unprotected~..." She let out a purr as she spread her legs for him, biting her lip with her fangs in anticipation. Spike let out his cock from its sheath, and she gasped at the sight of it. "Oh~! It's so large~! Surely you aren't going to use it on me? You'll split me in half with that monster~!"

Spike grinned wider, licking his lips at the sight of her already dripping pussy. He closed in and began to gently press his cock against her nether lips, as his hands traveled up to fondle at her magnificent rack. He reveled in her feminine moans for a moment before gently thrusting it into her, getting a pleasant gasp out of her. He quickly began to pick up his pace, both in fucking her and in his groping, trying to keep in play with their little game.

"Oh, gods yes, ravage me~! Rip into me, you beast~! I'm yours! Yes~! Fuck me~!" She rocked her hips against his desperately, wanting him inside of her.

"You like it, you little slut of a queen~? You like being defiled by cock like a common whore~?" Spike taunted, the words slipping off of his tongue. And judging from the noises the queen made, she enjoyed them greatly.

The queen's wings flared out as she let out a pleasured shriek and came hard for him, only making it easier for him to slide his cock all the way in to her, fucking her savagely with his draconic dick, deeper and harder and faster with each wild thrust. His claws squeezed and groped at her royal chest, playing roughly with her round supple tits. He was loving this as much as she was, and deep down he knew that he could get used to this sort of play. He didn't have to fight back, and there was nothing wrong with fucking for fun as long as his partner had fun with it too.

They kept it going, hard and fast, Spike bringing the queen to a climax once more before finally he felt the pressure build. "Are you ready, my queen? It's time for you to take my seed~!"

"Oh yes~! Give it to me~! Impregnate me with your brood~! Fill my royal snatch~!" With that, he let loose his dragon sperm into her in a massive torrential stream, flooding her pussy with his hot jizz. She screamed and writhed in lust as he pumped his cum into her, and he couldn't help but grin at the sight of her stomach slowly start to bulge up with his cum. Finally, it was done. He pulled out as his cock began to recede inside of him, and the queen pulled him down into a loving embrace.

"That was magnificent~... thank you, noble dragon, for giving me this gift... it has been so long since I've found someone worthy enough to pleasure me like that... Please, should you ever feel the need to, come to me again. I'd love for you to grace my bed once more~." With that, she gave him a full kiss on the lips, one that he was more than happy to return. "Please... stay and lay with me a while... I want to feel your arms around me... you know, you never gave me your name good sir. Quite rude of you~."

He grinned as he wrapped his arms around her as they huddled together. "I'm Spike. Spike the Dragon. And you, my queen?"

She grinned back as they huddled closer together. "Oh, how rude of me for not properly introducing myself~! I am Queen Desmoda. And welcome to my kingdom~."

Author's Note

Phew! That was fun!

As a side thing, I've decided to do a small bestiary type thing down here for all of the original creations I've added in so far. Hope you enjoy!

Bat Gremlin: These winged creatures are distant offshoots of the goblin race who, instead of worrying about starting new clans, decided to use their drive to breed to come together as one collective to try and build an army against the demons. Fast and agile, yet frail to most attacks, they prefer to use their speed and wits rather than brute force. Not to mention their sonic screams that can momentarily deafen most enemies. They also tend to prefer to fight in swarms, since alone they aren't very strong.

Bat Nip: Bat gremlins harvest this plant to use as a drug, bringing them into a sort of frenzied state in which they aren't completely aware of their actions. It's said that the drug also works on other races, but with unintended side effects.

Vampire Bat Gremlin: Vampire gremlins are the result of a bat gremlin mating with a corrupt being such as a demon. These gremlins are larger, more dominant, and definitely more powerful than their smaller variants. However, they don't use strength to fight. Instead, they use their hypnotic gaze to lure in their prey. The longer you look into their eyes, the more your mind clouds and the harder it becomes to escape. Thankfully, they get so turned on by their own ability that often they end up forgetting to maintain eye contact in their lust-filled state.

Bat Blood: Vampire gremlins have special needs when it comes to what they eat, and what better than a mixture of blood and powdered bat nip to give them what they need! It doesn't give the same frenzy that bat nip does, but it still packs a punch!

Bat Queen Desmoda: The first and oldest of the bat gremlins, she is seen by all of her subjects as the mother of their race. She loves all of her 'children' equally, and only wants a safe world for them all. She hates that they had to be driven underground like this, and wishes to defeat the demons to prove that the gremlins are more than monsters of the night. She is willing to go to any measure to ensure that her people are safe and happy.

Fire Ruby: Not much is known about these strange stones that glow like a fire. Legend tells, however, that they are the crystallized souls of a powerful race of beings called ifrits, known for controlling fire and for living deep in the desert. No one knows how true these legends are. All that is known is that fire rubies contain a great amount of magic.

And that should be it!
