A Spiked Maternity

Scene 1:

“Now Shiny, you promised to help….”

Shining Armor trembled gently on the floor, his cheeks tinged pink with a mix of embarrassment and shame at his current situation.

“Something just went wrong, and this is the only way to reverse the spell. Magic involving dragons can be very unpredictable due to their inherent magical abilities.”

Twilight giggled.

“Although I will admit, it usually doesn’t involve a complete egg regression.”

Twilight closed her eyes as her horn lit up, and Spike’s egg gracefully floated into the room.

“Now, you promised you’d help me out, and I know you’d want to help Spike, so I guess I just don’t understand what the big deal is?”

“It’s huge! You said he’d turned back into an egg, but look at the size of it!”

Shining winced nervously as he watched the floating egg looming over his rear.

“Nonsense Shining, you know dragon maturity doesn’t work like that! Now suck it up and get it together, the longer we wait the longer it will take to incubate him.”

“J-just a day or two, right?”

“Of course, any longer and I’ll look for another solution.”

Twilight smirked, and gave her brother’s raised rump a gentle stroke.

"Besides Shiny, anything for the family, right?"



Scene 2:

“Y-eah, but Twily-y-y-y!”

Shining’s voice cut out as Twilight began grinding the tip of the egg against her brother’s anus, prodding and spreading it, testing it’s tightness. Shining clenched his eyes and gritted his teeth as his body flushed at the sensation.

“Don’t worry Shiny, I’ll make sure that you don’t feel any pain. You may just feel a slight bit of discomfort from the pressure, along with a few other sensations…”

Twilight smiled to herself, and gave the egg a counter-clockwise twirl. She watched her brother’s face twitch and grimace as he tried to hold in a gasp.

“Maybe just a little bit of lubrication, to make this easier for you.”

Twilight’s horn pulsed stronger for a second, as Shiny’s anus began to moisten and leak a clear fluid.

“Okay my sweet BBBFF, on the count of 3. 1… 2….”



Scene 3:

Twilight stood up on her hind legs, and with a sudden push and a burst of energy from her horn, shoved the egg against Shining’s asshole

“... 3….”

Shining’s eyes snapped open as he let out a long breathy gasp.

“Guuuhhuuunngnnghhh….”

Shining panted and shuddered as his body flushed red with blush. He struggled to focus his eyes ahead of him as the sensations in his ass overloaded his mind and his body. He trembled as he felt the egg gaping his ass wide open, and as his cock tingled between his legs. Behind him, his sister tried to contain her giddy enthusiasm.

“Oh Shiny, what was THAT!? Don’t tell me that you’re enjoying having your ass gaped wide open and stuffed full?

Twilight gave the egg a twist in his ass, deliberately holding it at it’s widest point.

“I thought you didn’t want to do this, but now you’ve got me all confused. Do you want it or don’t you?”

Twilight’s voice dripped with condescension as she teased her brother.

“Well Shiny, that wasn’t a rhetorical question…. Tell me, do you want this?

Shining could feel his ears burning red hot with shame and embarrassment, but even worse was the pre he could feel the egg milking from his prostate. He swallowed his pride.

“Y-yes…. “

“Yes what, oh dearest BBBFF of mine?”

Shining’s voice became very small and quiet.

“I want it… the egg… inside of me… please….”

Twilight grinned.

“How could I refuse my own brother?”



Scene 4:

Twilight gave Spike’s egg the slightest push, and then stood back to watch Shining’s ass do its work. His anus gripped around the egg tightly, pulling it in deeper as it struggled to contract back to its once tight pucker. Shining quivered and moaned quietly as the egg slid slowly inside of him, pressing against his prostate and squeezing out a long strand of precum. Twilight was mesmerized, watching the subtle twitching of her brother’s anus as it engulfed the egg, pulling it deeper and deeper inside. She could feel her heart pounding in her chest and her stomach fluttered with excitement.

“Oh Celestia, I can’t hold it back anymore….”

Twilight closed her eyes and visibly relaxed as her fat cock flopped out beneath her. Beads of sweat formed on her forehead as the repressed lust hit her all at once, making her squirm and squeal from the denied pleasure. Twilight struggled to regain her composure.

“Oh Shining, you have no idea how much you’re turning me on right now. My own brother, becoming a pregnant egg bulging mother for his sister, it’s a dream come true~”

Shining shuddered with pleasure as his mind emptied. His eyes stared ahead blankly as he moaned with pleasure, leaking saliva and precum onto the floor.

Twilight looked back to Shining’s puckering asshole as it struggled to swallow the egg into the deepest recesses of his body

“It looks like Spike needs a little bit of a ‘push’ to find his home nestled deep inside of you... and I probably should have mentioned that dragon eggs need to be fertilized with seed… and I just don’t think you’re in any position to serve that purpose….”

Twilight positioned herself behind her brother, her cock twitching wildly as she rubbed it up and down against his winking asshole.

“Your slutty asshole is just begging for me to fuck it full of my hot cum; twitching and gasping like a hungry mouth. I’m starting to wonder who’s doing who the favour here, Shiny….”



Scene 5:

Twilight climbed up onto Shining’s bulging body, her hooves dangling just off the ground as she rubbed her cock up and down against her brothers gaping asshole. Shining shuddered from the sensation, the intense pressure of the egg threatening to take him over the edge at any moment. Twilight leaned over to her brother’s ear and whispered, teasingly.

“This is it Shiny, no going back now. Once I’ve nestled this egg inside of you we’ll have to let nature take it’s course….”

Shining shuddered at the sensation of his sister’s breath on the back of his neck, and couldn’t help but nod his consent. He couldn’t turn back now; he needed this. Twilight nipped teasingly at Shining’s blushing ear as she pressed the flare of her cock against Spike’s egg.

“Oh Shiny, it’s already so warm! And your twitching ass is just begging to grip tight against my cock!”

Twilight pressed her hips forward, pushing the head of her cock against the egg, shifting it slightly. Shining let out a long moan of pleasure as Twilight forced the egg deeper and deeper inside of him, following it with inch after inch of her own throbbing cock. Suddenly, he felt a shift in pressure as the egg popped into place as it came to rest inside of him, nestled perfectly in place. He let out a long heavy sigh of relaxation as his body began to accommodate to its newest feature; a large heavy egg and a belly to match. Twilight nuzzled her muzzle into the back of Shining’s neck, kissing and snuggling him gently.

“Isn’t it perfect Shiny? That constant warm feeling of fullness?”

She rubbed her foreleg on the side of his belly in a slow circular motion.

“And you make such a gorgeous mother too! You’re positively glowing with radiant beauty, my sexy egg bearing BBBFF. But you’re not quite a Mother yet….”

Twilight pulled her cock out in one quick fluid motion, letting his fat swollen asshole twitch and gape for only a second before plunging it back into him, slapping her balls heavily against his own.

“Haaannhhahhhh!”

Twilight began mercilessly pounding her brother’s already abused anus, slamming her cock in and out, and mashing his prostate as she slid between it and the egg.

“That’s it Shiny, moan for me! Let it all out! I want to hear how much you love this, how you want it, NEED IT!”

“D-don’t stop… p-please Twily-y-y-y….”

Twilight slammed her cock into him with full force and began grinding it deep inside of him, holding it there as his anus convulsed greedily on the base of her cock. She whispered in his ear.

“Beg me for it Shiny… I want you to beg for my cum deep inside of you, for my seed to fertilize Spike’s egg and to make you the Mother that you’ve always wanted to be. I want you to let it all out and tell me how you can’t imagine living any other way than being an egg filled broodmare. Beg for it…. ”

Shining didn’t even barely let her finish; between the intense pleasure and the wave of emotions overcoming him, he had to have this. He needed this to be his life.

“Please Twily! I want this so badly! I need you to make me the perfect Mother! I want to milk every last drop of hot jizz out of you, to be the spitting image of maternity with my bloated belly, with cum dripping from my asshole! Turn your brother into your egg filled breeding WHORE!”

Shining trembled with emotion and pleasure as Twily bit down hard on his ear and resumed viciously breeding his boipussy. Every thrust caused his dick to leak a fat glob of precum, and he could feel her getting closer and closer as her cock throbbed in synch with his racing heartbeat.

“Shiny!!!”

Shining felt her cock root as the first powerful spurt of jizz shot deep inside of him. His eyes rolled up as he felt his own dick spraying cum over his distended belly, dripping down onto the floor. His sister released his ear as she gasped with pleasure, pumping load after load of her seed into him, soaking his bowels and Spike’s egg in her seemingly endless orgasm. Shining could feel his mind blank out as the overwhelming ecstasy took over, leaving him as a vacant minded, drooling mess…

Twilight collapsed on top of him, panting on his neck as she came down from her monumental orgasm.

“Oh Shining, that was… I can’t even describe how amazing that felt….”

She kissed at his neck.

“The next eleven months are going to be pure bliss together!”

Shining’s mind twitched, and his asshole twitched with it.

“Ooh, did that pierce the veil?”

Twilight smirked as she rubbed her hooves on his belly, helping the seed inside of him absorb into his body and the egg.

“I have a confession to make Shiny; there was no accident…. I planned all of this, down to a T. Spike was getting too boisterous, too uppity. I needed the sweet little mincing sissy that I had back in Canterlot, and what better way to do it than a full reset? And I knew I had the perfect host as well, just waiting for me….”

Twilight brought a hoof up to Shining’s horn, and started playing with it teasingly.

“I’ve always known that you wanted this, even if you didn’t. The way you’d look at the old pictures
of when Mom was pregnant with me, how you’d stare longingly at pregnant mares in the street. You reeked of envy…. But now you’ve got your dear sweet sister to help you along, to help you fulfill your hidden dreams.”

Twilight tittered to herself.

“We’re going to have so much fun Shiny, you’re going to be the spitting image of motherhood! Mmhmm, so many plans, so many ideas…  though, what to do next, what to do! We could go straight to your loving wife and show her the good news; tell the crystal empire that the royal couple is with child…. Or maybe I could sneak you off to Ponyville first, have Rarity get the measurements on all the new outfits I’m commissioning her for to get your new look started! But perhaps we should just take it slow at first; help you adjust. A spa day would be the perfect way to relax and get you settled into your new lot in life. Decisions, decisions… tell me, what do you think…?”
