Spawn
Written by CodenameOne

It was a warm Friday night, and Twilight Sparkle had the windows open, letting the air flow through her room in her new home, the Castle of Harmony. The castle was pleasant, lovely even, but it wasn’t as homely as the library had been. It was too cold; too much marble, too much stone.

The fireplace in her bedroom helped, though.

Next to Twilight lied her boyfriend and life-long friend, Spike, temporarily turned into a pony, as he had been born a dragon. He had his eyes closed, and was rubbing Twilight’s stomach with a hoof. The adjustment to his new form was difficult, and Twilight wanted to make sure he was fully comfortable in his new skin before engaging in tonight’s activities.

With a tender kiss on Twilight’s neck Spike looked up into her eyes, asking “are you ready, my love?” Twilight reached around behind Spike’s back and idly rubbed at his dock, where his tail turned from hair to flesh.

This day had been a long time coming; Twilight had poised the idea of children to Spike a while ago, and he had agreed eagerly. Twilight had even prepared to try and convince him to go through with it, but he surprised her. Seems he had been wanting to have some, too. They had had to wait until Twilight’s next estrus cycle, which began tonight. Twilight could already feel her loins start to burn as her body put her into the more fertile state.

“Yes, it’s starting. Let’s do it, Spikey” Twilight whispered, kissing the now-stallion. Rolling over, Spike got on top of her, transitioning to his dominant state of mind. When he was a dragon, it was even more exciting as he was another species; it was more exotic, and erotic. However, Twilight wouldn't be able to get pregnant if he weren’t a pony.

He wasn’t erect, yet, but he started by kissing Twilight’s neck and caressing her body. They had abstained for a week in order to build up Spike’s own virility. By now, he had a healthy and plentiful load of seed to ensure the highest probability of impregnation.

Placing his hooves on Twilight’s hind legs Spike spread them open further, getting her ready. Eyeing her slit the now-stallion leaned down, giving the sensitive region a lick. Twilight shuddered, her libido rising. She knew she was about to start secreting fluid any second now.

A hoof found its way to Twilight’s butt as Spike wriggled it under her body, rubbing the bubbly cheeks. It wasn’t any where near as good as when he did it with his hands when he was a dragon, but when in heat any touch set Twilight off.

At the sight of Twilight’s snatch and sounds of her sighs Spike began to grow erect, his shaft poking out of its sheathe. Twilight had let Spike get used to this part of his body by allowing him to become erect earlier in the day, the now-stallion awed by the increased girth he got with the stallion penis. Spike always had very little trouble satisfying Twilight; what with the hands and the nature of his being a different species the alicorn mare was able to cum with relative ease. Tonight, though, Twilight wasn’t looking for an orgasm; she knew she’d have one, probably more, but Spike’s orgasm was what was important.

Now engorged to full length Twilight watched Spike’s cock throb, each beat of his heart making the long member pulse. Spike smiled, leaning down and kissing Twilight, the penis pressing against her stomach; it was warm and stiff.

“I’m a lot bigger now; do you think you’ll be able to take me?” Spike asked, still rubbing Twilight’s body. She was really starting to get worked up, and honestly just wanted Spike to stick it in already, so she answered quickly.

“We’re meant to take large penises, Spike. Now please just rut me.”

No further encouragement was needed, and Spike leaned back, pressing the head of his cock to Twilight’s snatch. With a prod, his rod spread her lips open, and pushed into her pussy, eliciting blissful sighs from the mare. Spike pushed more, and quickly hilted. Twilight was ever tight, but she accommodated his large size with relative ease. The sensations on Spike’s end were pretty much the same, but he enjoyed them more with the many extra thousands of nerve endings his extra size granted.

Leaning back down Spike kissed Twilight, making out with her as he pulled back, beginning his thrusting. Involuntarily flexing his cock Spike felt his head flare and then contract again, growling at the surge of pleasure. Twilight put her hooves up on the now-stallion’s shoulders to brace against the thrusting. Spike always got deeply into the sex, to the point where he’d growl, blow smoke, thrust very hard, and dig his claws into Twilight’s back. The studious mare discerned from her books that it was part of his dragon instinct; to be naturally dominant and forceful. Usually it wasn’t a problem, as his thinner penis didn’t stretch her as much, but this time it was a little much.

“Nnnngg, Spikey...” Twilight groaned, looking into the now-stallion’s face. He was gritting his teeth, but still had enough control to keep his eyes open and look back at the mare.

“Fuck, yeah....” Spike growled, pushing up to focus on fucking his marefriend. Twilight loved how dominant he was, and seeing him standing over her, hooves on either side of her and his huge stallion cock penetrating her formed the trinity of bliss.

“Oh Goddess, I’m going to cum soon...” Spike uttered, continuing his pounding. With each plunge his ballsack slapped against Twilight’s bottom, the rhythmic tap aiding Twilight along on her own journey to orgasm.

Closing his eyes Spike raised his head up, teeth bared and grit together. Twilight could tell he was trying to hold back so she could cum first, which was definitely going to happen soon. She also knew that the now-stallion wouldn’t last very much longer; in her experience the longer Spike abstained the shorter the sex was when they finally did get to do it, but she appreciated his efforts.

“Oh yes, fuck me!” Twilight yelled, her walls clenching. The slap, slap, slap of Spike's crotch on her clit finally pushed her over the edge, and she squealed as her walls spasmed, excess juice spilling out around Spike’s shaft. The clenching triggered Spike, and he hilted himself as he bit Twilight’s shoulder hard, his stallion cock flaring with each thick rope that shot out into Twilight’s cervix, flooding her with potent seed. She loved the pain and pleasure and knowledge that right now millions of sperm were racing to her eggs to finally give them a foal of their own, her orgasm stretching on a little bit longer at the thought.

“AGGHH! NNNNGGGGAH!” Spike screamed into Twilight’s shoulder, biting even harder and drawing blood. As his orgasm subsided and some semblance of his faculties came back Spike pulled back, releasing his teeth from Twilight’s shoulder. His throbbing slowed as his spurts ended, the contractions transitioning to shudders as his system ended the orgasm.

“Fucking... Yes... Ah, Goddess, that was amazing” Spike commented, panting. He opened his eyes and looked down at Twilight, his gaze immediately turning from the mare’s eyes and at the blood pouring down her shoulder and seeping into the blanket. It wasn’t gushing, it wasn’t even actively bleeding, but there was fresh blood still seeping out.

“Oh Goddess, I’m so sorry, Twilight! We better stop that bleeding” Spike said, pulling out. Twilight had passed out from the orgasm, however, or maybe the blood loss. Spike couldn’t really tell, which really worried him.

Getting up from the bed Spike was about to head to the bathroom when Twilight came back around, calling him back to bed. “Forget about it, stud; it’ll stop on its own. It’s kind of hot, actually” she growled, the estrus talking. “Now come on, stop fooling around and get back in bed. The night’s still young, and you’ve got a LOT more thick, gooey, lovely cum to deposit inside me.”

Spike was still hard as he climbed back into bed, immediately and forcefully pushing himself into Twilight’s cunt. “Oh yeah, I’m gonna fuck your brains out, sweetie” the now-stallion declared, his dragon instincts overriding the concern.

“Oh yes! Rut me!” Twilight yelled, spreading her hooves out across the bed. Spike gritted his teeth and started thrusting again, Twilight looking at him with glazed eyes.

Within minutes the two were screaming again, both fast approaching orgasm. Their sensitive nerves screaming. Twilight clenched and squirted again, followed by Spike’s cock blowing another load of seed in Twilight’s snatch, filling her up even more. Pulling out some of the cum followed, leaking out of Twilight’s gaping pussy and down her butt.

“Again! Yes! Goddess, yes! Bite me! Come on, bite me again!” Twilight yelled, the estrus talking again. Spike obliged, his teeth digging into the mare’s flesh on her other shoulder. He didn’t draw blood this time, keeping conscious enough to be mindful of the potential of his teeth. Twilight didn’t mind, though; the pain from the bite was good enough to send her squirting another load of mare-cum onto Spike’s cock.

Releasing his hold Spike stuck it back in Twilight, pounding her harder this time. He felt his stallion cock flare erratically and anus contract as he blew another load, his cum spurting into his mare, his conquest. Most of it was leaking out now, as her insides couldn’t hold any more of his virile seed.

Pulling out one last little spurt landed on Twilight’s stomach, and she immediately scooped it up and licked it up. Spike growled ferally and collapsed onto Twilight, exhaling hard out of his nose. Reaching down Twilight furiously rubbed circles around her snatch until she came again, her pussy expelling more juices onto the sheets, which were now completely soaked in that area. Without Spike’s stallion cock to keep the flood contained Twilight’s crotch and legs were sprayed, become matted with the fluid.

“Aahh! Ah! Yes! Oh fuck...” Twilight exclaimed, passing out immediately after. Spike chuckled, rolling onto his side next to her, his softened but still exposed cock draped across her belly, the last few drops of seed seeping onto her fur. He nuzzled into his mare’s neck and exhaled hard again, content with their efforts for the evening. The sex wasn’t over for the week, but Spike knew it wouldn’t be as intense as all the times before, now that Twilight was assuredly pregnant.

Spike smiled, knowing that in eleven months he would be a father. For now, though, all they could do was prepare for the foal, and continue with their bedroom romps. Spike’s smile turned to a dragon-like grin; he’d be turned back to normal by tomorrow, and Twilight would still be wanting sex. He was looking forward to being back in his usual body, and looking even more forward to digging into her body again with teeth, claws, and cock.

“I love you, Twilight” Spike whispered, closing his eyes and settling in for sleep.

I'm going to Florida for the next week, so I wanted to post something for my readers before I left. Since SpiLight was asked for, SpiLight was delivered. Wrote this quick, so errors are abound, I'm sure.
