How to Bust your Dragon Mate

*A/N: This a How to Train Your Dragon ballbusting fanfic between Toothless and Luna (the fan name for the Light Fury). The characters here are slightly anthro, simply because it’s easier to write for me. If you need an idea of what I’m thinking of, imagine this:(*[*https://rule34.xxx/index.php?page=post&s=view&id=520992*](https://rule34.xxx/index.php?page=post&s=view&id=520992)*) Also, this was written entirely on mobile, so there’s probably mistakes I’ve just missed. When I get home I’ll edit. Anyways, that’s about it. Thank you for reading. Upvote if you liked it, comment if you have a suggestion or something, and have a great day! Until next time!*



To be entirely fair, Toothless knew exactly what he was getting into.

He was laying with his back against a rounded wall on the side of his cave, wings and rear legs equally spread, tail laid against one leg and his forelegs resting limply by his side. The glowing moss and flora that populated his hovel gave the normally hard and unforgiving stone a softer feel to it. It was nice, and comfortable.

Perfect for what he knew was coming.

He’d only had to sit there for a short while, not too long, but long enough that he’d nearly dozed off when he’d heard the telltale sound of wings flapping followed shortly by a quiet thump.

His eyes opened to see his love, his one and only, Luna. Her beautiful white scales almost glowed in the dim lighting, giving her a very regal look. Her eyes, piercing blue, were narrowed at him as a small grin adorned her visage.

His heart started to beat faster in excitement.

She strutted over to him, each step slightly exaggerated as she made a show of approaching him. Once she was only a short distance away, she stopped and bowed her head.

“My humblest greetings, my Alpha.”

Toothless resisted a snort. He knew she was doing this just to draw things out. Still, she was putting in the effort, so he might as well meet her halfway.

“Raise your head, my subject.” The words themselves tasted strange on his lips. He never liked referring to other dragons as his subjects or underlings, or anything like that, even if that’s what they were. Many of them he’d known for years, back before he and his human had fought and defeated the Alpha. Some he knew even before he’d met his human that fateful morning.

Luna raised her head, giving him a playful look. “What can this one do for you, Alpha?”

Toothless shifted his hips slightly, bringing her attention down towards his groin area. His sizable cock had already slipped from its sheath and hardened, sticking up proudly. Just below sat his his rather large, black-scaled ballbag, laying softly on the ground on a mound of bioluminescent moss.

“Oh I see.” Luna spoke, giggling lightly. “Well, who would I be to deny my Alpha some relief? May I have a seat, my Alpha?”

Toothless could feel his heart going a mile a minute as he nodded and watched as she turned around. He got to stare at her ass for a few, quick moments as she backed towards him before she tucked her tail in and then sat down heavily.

Directly on his balls.

He squeezed his eyes shut as Luna’s supple rear pressed his balls against the floor, the moss they’d been resting on doing little in the way of cushioning. Pain flared up from his groin, shooting through the rest of his body like a lightning strike as the contents of his ballsack were flattened beneath the Light Fury’s ass.

“…..god….” Toothless murmured through grit teeth as his claws dug into the wall and floor.

Luna let out a hum and shifted slightly. After a moment, she lifted herself, granting Toothless a moment of reprieve before her ass dropped back down, further squashing the Night Fury’s private parts into the ground.

Toothless grunted in pain, lifting his head up and pressing it against the wall as he looked at the ceiling. All he knew in that moment was the feel of Luna’s ass and the long, aching pain of his flattened dragon-makers beneath it.

His cock twitched a bit, the tip smothered with pre-cum.

“How was that, my dear Alpha?” Luna asked.

“….keep going.” He murmured, quickly catching his breath. “Flatten your alpha’s eggs, my subject.”

She gave him a sultry smile.

“Of course, my Alpha.” She replied, before lifting herself upwards and subsequently slamming her rear down on his testicles.

“Urk!” Toothless groaned out, body tensing from the third heavy blow to his balls. He shifted forward, pressing his stomach against her back and resting his chin on her shoulder, tongue lolling out of his mouth.

Luna leaned back against him, pressing him back against the cave wall and unintentionally pressing his balls even flatter against the ground.

His cock, now sandwiched between his stomach and her back, began twitching violently.

Luna must’ve felt it, because she leaned her head to rest against his.

“Get ready.” She whispered into his ear, the act causing him to shiver. “I’m not stopping until you cum.”

What followed shortly was a ballbusting session that would go down in history, retold again and again in small-time conversations between friends and late night conversations between lovers. Many attempts to recreate the event were made, much to the pleasure of many females and the displeasure of many males.

In a display of strength and endurance that only a Night or Light Fury could pull off, Luna bounced up and down on top of Toothless’ testicles at an almost ridiculous speed.

The Night Fury’s testicles were strong and durable, much like the rest of him. However, he felt pain like any other creature on the planet. So each time Luna’s butt slammed down on his scaly ballsack, he grunted, groaned or yelled in agony as his dragon-makers were flattened again and again beneath his mate’s shapely rear.

*Thu-wack!*

“Gah!” Toothless yipped, legs twitching as he fought the instinctual reaction to cover his brutalized tender bits from the Light Fury’s assault. Instead he forced his limbs to stay slack, even as Luna lifted herself upwards for the millionth time, only to drop back down again.

*Thu-sqwuick!*

“Guuuu\~” The Dragon Alpha mewled like a hatchling as his mate gave his male-hood a particularly crushing hit, the twin orbs crying out for help as Luna shifted her ass, squashing them even further.

Toothless felt his cock twitch and pulse with desperate need. He could feel himself approaching the edge, the pain from his balls mixing dangerously with the pleasure from his cock to become a violent, pleasure cocktail that was threatening to erupt.

“….L-Luna… I-I’m going….going to…” He could barely speak.

Luna gave him the barest of nods before she lifted herself up off his ballsack, leaving his bruised and flattened ballbag almost plastered to the floor while his cock twitched in denial, the tip covered in pre-cum.

He watched in confusion for a moment as she stood up on her hind legs. She glanced back, looked down at his balls for a moment before meeting his gaze and giving him a Cheshire grin.

The confused expression swiftly changed to shock as Luna took a standing leap directly upwards, bringing her legs up so her ass was pointed directly downward.

*THUDDD!!!!!*

With the force of a thousand suns, Luna’s butt slammed into Toothless’ battered testicles, crushing them to near the breaking point as his balls fought to stay at least somewhat in shape.

The Night Fury’s eyes were wide, his body motionless and his mouth open is a silent scream. Then, a moment later…

*Spur-spl-splurt!!!!*

Cum like a geyser erupted from the dragon’s cock, coating his stomach and Luna’s back in a thick layer of hatchling batter.

The Light Fury crooned in joy as she felt the thick, warm liquid coat her lower back as her lover’s cock slowly softened and stopped twitching. With a heavy sigh, she leaned back against her mate.

“That was wonderful, wouldn’t you agree Alpha?”



“Alpha?”

After a few more moments of silence, Luna turned around to see Toothless was slumped over, eyes closed and mouth hanging open as he let out a quiet snore.

She giggled at the sight before letting out a happy sigh. Walking over, she gently slid Toothless down the wall until he was laying down. Giving him a small kiss, Luna quietly walked over to the cave entrance, gently wiping the cum from her back before slurping the delicious hatchling batter down.

She sat down at the cave entrance, feet hanging over the edge as she stretched her back and wings, as both had gotten kinda tense while she was busting her mate’s balls.

She chuckled. The idea that Alpha Toothless, a dragon that was well-known practically world-wide for many things, most of all for taking on a war-mongering Alpha and beating it, liked to have his balls busted by his mate, made her want to laugh.

Still, he trusted her to keep his kink a secret, and she wouldn’t break his trust. However, in return, she’d wanted free reign to bust his balls whenever she wanted to in private. Of course, he’d been more than okay with that, and as such, for the last year or so they’d been together, she’d spent a majority of their private time kicking his balls into his throat, whipping them with her tail, chewing on them as if they were a plump fish, etc.

She was brought out of her thoughts as she heard a small groan come from her beloved. Glancing over, she saw Toothless shift for a moment as his eyelids fluttered, and then opened.

He stared upward for a moment before he blinked and looked around, finally spotting his beautiful mate. He gave her a pained smile.

“Hey Luna.”

“Hello Toothless.” She replied. “How are they feeling?”

He shifted and grimaced. “Like a gorgeous dragoness just crushed them to pulp.”

The Light Fury grinned mischievously. “Aww. Do you want me to make them feel better?”

Toothless chuckled. “I wouldn’t say no.” He noticed his cock, which somehow had once again hardened, the pink flesh-rod twitching slightly. “Neither would he, apparently.”

“We’ll, let’s not waste any time then\~•

She walked over to where the Night Fury was. Laying down, she crawled sensually towards her mate’s groin. She reached out and gently took a hold of his cock, causing him to let out small gasp.

She gave him a grin. “Get ready, cause I’m going to rock your world.”

He smiled.
