My Little Brony: Chaos is Magic

"Ahh...That feels real nice...Mhmm, it tickles real good and all...but...Please! Buck my brains out...I can handle it..."

Sweetiebelle moaned, not exactly enjoying the slow fucking I was already maintaining.

"Ahem...This sure isn't awkward or anything...Just about to release my seed into a small pony...Let alone Rarity's Sister...But what the hell! I already did it once...Why not again?"

The constant thoughts of myself stopped me from finishing the intended job...

I look down on my lap to see Sweetiebelle staring up at me...Almost in a comatose state of pleasure, she remain eyes half shut, her face a heavy blush...Hard to believe my dick actually fit inside her, I felt as if I should've been poking her uterus by now...

"Hmmngh..."

Sweetiebelle sighed, laying back in my arms as I thrusted my hips upward, no doubt the visible bulge beginning to throb as I picked up the pace. It was really embarrassing to know that I couldn't handle Sweetiebelle...she was so tight!

Therefore whenever my dick would absurdly pulse....

"Oh! I can feel it...Mhhm! It's tickling my insides..."

Sweetiebelle blurted out, starting up with a series of continuous moans and sighs, her eyes widening as we both just stare at eachother...

The loud sounds of penetration causing a show for the mares in the Clubhouse to spectate...

"You can do it, Sweetiebelle!"

"Heh, make sure she gets filled Orion..."

Applebloom and Scootaloo both say, confident for their friend and her lust for cum, which at the time I could not think about...

"Oh!"

Sweetiebelle stopped her statement, instead, she just took it...All of it...Constantly whining on the same rhythm as my cock expelled her insides full of semen. She remain grinning down at her stomach, staring at the bulge as more and more cum filled her up...

"It feels..."

++++

"Wow...Look at all of..."

Pinkie stopped, as the screen turned from pink, to filled with white in an instant! The swarm of white tadpoles traveling up the uterus, searching for...

"Mhhm! Would you look at that..."

Screwball said cutely, moving the screen to show Sweetiebelle's ovum...

"Is that what I think it is?"

Twilight asked with bright shiny pupils, the sperm almost attacking the egg instantly, trying to break through...

"Twilight, I may not be no fancy smancy Pony doctor, but...Won't one of those lead to a..."

Applejack stopped, almost thinking on what the hell this creature inside Sweetiebelle would be...

"Silly sperm! Sweetiebelle isn't for humans..."

Screwball giggled as she zapped the screen, more importantly Sweetiebelle's insides, with a lightning bolt...

"There...now no matter how much sperm, only one can make it inside..."

"Wait! Don't we want ZERO sperm cells to enter the egg, Screwball?"

Twilight inquired as Screwball just giggled...

++++

"Oh...Orion...I feel very ticklish inside here..."

Sweetiebelle sighed, my dick still pulsing by where she said felt funny...I look down to see the bulge, and how close it is to this "funny spot," which was probably her uterus.

"Aww, it feels so nice!"

Sweetiebelle moaned, laying down on the mattress as I began fucking her again...Her legs open as far as they could spread as I had a stupid idea to give Sweetiebelle more...

"More! I want...more!"

Sweetiebelle sighed, slowly wrapping her hooves around my neck as my dick locked inside...Overfilling her pussy...

++++

"Aheh...Alot more! And you're certain NONE of them are able to fuse?"

Dash sighed, as one by one my DNA filled Sweetiebelle's uterus, more and more sperm cells attacking the egg.

"As long as she doesn't want more...I think we're good...Wait! What the buck is happening now!?"

All the mares watched as lucky Sperm number 935 made it's way inside the ovum, a bright pink light filling Sweetiebelle's egg as the sperm tail finished it's way completely inside.

"Well...we're bucked..."

Lyra sighed, as the egg remain constantly flickering a dim pink to a bright neon pink, then eventually into a cloudy looking red.

"Yup..Silly me! I forgot to disable Spike's spell..."

Screwball smiled, putting her hoofs together, as if in some plan...she had succeeded.

++++

" I love you so much! Heh, it feels like a party in here..."

Sweetiebelle giggled, rubbing her tummy where my dick was, she then gave me passionate affection, constantly kissing and hugging... and I fucking loved it! The thick bulge had ceased and I was ready for another mare...Just after a couple of minutes at least...But instead...

I kissed Sweetiebelle's cheek, continuing down her fur...Until...

"She's asleep..."

I say to myself, while slowly leaning back, away from beautiful Sweetiebelle passed out on the mattress cushion. The moment I turn around to face the mares I get glomped with affectionate kisses and holds...

"Please buck me..."

Scootaloo, Applebloom, and Cheerilee each said, sitting on their flank, tail blocking view of their slit...The look in their eyes...It meant I shouldn't have put on a show that good...

++++

"So what was that universe idea you mentioned...?"

Twilight eagerly purposed to Screwball, who just kept gazing upward into the now clear sky...Suddenly cleared by a new bright star that remain vigilant over Equestria.

"Well Twilight, I'd be spoiling the fun if I told you...But every plan begins with a single step..."

Screwball stopped as she stood on hind hoofs, walking towards the screen displaying,"My Little Pregnancy."

"This is step one...Secure the keys...Ehyup!"

A smirk grew upon Screwball's face, her cap whizzing as a strong breeze filled the night sky...

Only STEP ONE!? OUT AH EIGHTEH?

...and a foal is a key to what now!?
