Well, that's a little...
"Come on, runt." Tempest commented, mocking at the smaller dragon in front of her. "Punch this bag."
At the Ponyville Gym, Tempest Shadow, the once former commander of the Storm King's dreaded armies, was not shouting commands at Spike, the resident, friendly dragon. He was standing in front of a punching bag, the mare leaned against it as if bored and annoyed. His clawed hands were stuffed in a pair of boxing gloves, and he was trembling a little as he looked at the bag that was nearly three times his size. The mare only continued to glare down at him, unimpressed and losing patience with his hesitation.
"But...but Tempest..." Spike commented, shivering nervously as he felt overly intimidated by this taller mare. Even his wings seemed to shiver at her gaze. "W-why do I have to do this?"
"Like I told the Princess. You're a dragon." Tempest exclaimed, rubbing her temples in frustration. "And the dragons I've seen have been big, scary, or at the very least, strong." She pointed at Spike. "You are none of these things. You're a disgrace to dragons!"
"I...I wouldn't say that I'm..." Spike stuttered a little, not really able to look Tempest in the eye. "I...I can be big...and strong..."
"Then prove it." Tempest replied, glaring down at Spike with cold, cruel eyes. The dragon hesitated. Sighing, she walked over to him. "Fine, I'll have to force it out of you."
"What are you-" Spike tried to ask, but before he could finish a word, Tempest punched him in the stomach, knocking some of the wind out of him. He gasped as the air left his lungs. Falling back, he twitched and clutched at his belly. "T-Tempest...what was-"
"Get up." Tempest said coldly, glaring down at the dragon. "You can get up, and prove me wrong. Or lay there, and pass out, like some weak...pathetic-" Her words were cut off, seeing that Spike had already passed out. She scoffed. "Typical, the Princess was right, you can't handle it." Sighing, she turned to start taking down the punching bag. Suddenly, she heard a sound, like a low groan. "Look, kid, don't even bother. Cause you're not gonna-"
Again, her words were cut off, but not by what she heard, but what she saw. Spike was laying on his back, his chest huffing up and down as he was catching his breath. But it was what was poking from his gym shorts that caught the mare's attention. It was his cock, but it was big, so very, very big. Disproportionally big for a dragon of his size. Tempest paused for a moment, speechless at the sight of this dick, one that was almost throbbing in an intimidating fashion. Spike's body didn't stop there. It started to grow, swelling stronger.
Tempest hissed and moaned, pressing her body against the punching bag. Her tits bouncing as she couldn't stop but shiver and tremble. Behind her, hammering his massive cock in and out of her tight, sobbing wet pussy was Spike. But unlike the small, cute form he had before, he was massive. The pent up frustrations from lust, want, and desire had swelled his frame until it was a strong, muscular, and dominating figure. Fueled only by the urge to breed, he fucked this mare's pussy, his cock was stretching out her pussy, ruining her for anyone else.
"Fuck, fuck, fuck!" Tempest hissed, looking back at the dragon who was so brutally ravaging her. "Come on you huge bastard! Fuck me harder! Is that all you got?"
Spike said nothing, only huffed and panted, his conscious mind seemed to have faded to leave only the primal urge to breed. The mare was just his mate, a fuckable hole for him to drive his cock in and out of her soaking hole. Whether the two were compatible, for Tempest to bear his children, none of it mattered to him. All this primal, savage creature desired, was the sensation of dominating, conquering, and hoarding this pussy all for himself. Tempest might've been a proud mare, a strong mare, one who could face any challenge. That was then, now, she was his bitch.
"Fuck...how can such a...small...weak...fuck!" Tempest moaned out, crying out in orgasm as she could feel Spike's cock swelling and growing inside her as he was fucking faster and faster. He was about to cum, he was about to fill her up with his hot seed. "Shit...just cum already!"
Spike, or whatever was left of Spike in the mind of this draconic beast, didn't seem to register that Tempest was even speaking, let alone what she was saying. All that seemed to communicate to him was how tight she was getting as she was cumming her sloppy mess all over his cock. The dragon fucked faster and faster, feeling as his size was swelling. He was about to cum, the mare shivered as she could feel each throbbing moment of this dick inside her. Leaning more over her, Spike pushed his full strength into his thrusts.
Opening his mouth into a wide display of his large tongue, and sharp fangs, Spike roared out in orgasm, pushing so hard that it nearly caused Tempest to tear the punching bag from its chains as she could feel the dragon bottoming out in her. The mare screamed out as she came another large, wet release as she felt the hot spunk of this dragon flooding her insides. She could feel as her womb was being stuffed as the pointed tip of the dragon's cock forced its way past her cervix, making sure not a drop of his cum could leave her pussy as his throbbing cock stuffed her moist hole.
"Fuck...just...fuck..." Tempest moaned, her eyes rolling back as the strength was draining from her. Feeling faint, she collapsed forward, Spike's cock being strong enough to keep her help up as she went almost fully limp from exhaustion. "Guess...you're not...a runt...afterall..." Before Spike could even growl a smirk, the mare passed out.
