Contains ping pong balls, magic expansion n' shit and horse sexan
Twilight trotted into the library, happy that she was finally going to have a weekend to herself
She had just returned from seeing Spike off to his Dragon diaspora convention at the train station
Closing the door with magic, she shrugged off her saddlebags, eager to begin
She levitated a ping-pong ball from the kitchen counter to her mouth, and gave it a quick lick
Once it was sufficiently lubricated, she inserted it in her pussy.
It was big but she was prepared for that.
She felt it work its way up to her cervix, she used her magic to open up her cervix, and felt a rush of adrenaline and excitement as she drew closer to what she knew was coming
Once the ball plopped into her womb, she left her cervix open and she levitated the ball inside herself.
It was incredibly hard to lift one's self with magic, but a small ball? She'd been training with those since she was a foal.
The lavender mare licked her lips and closed her eyes, and she cast her spell.
The ball began to expand, and Twilight felt more and more aroused
She felt a rush when the ball touched the sides of her uterus, and she drew a hoof down to her marehood
As the ball ballooned outwards, it began to strain her uterus, which she had done many times before.
Her hoof wet from her own juices, Twilight gently grazed her clitoris, bringing a wave of arousal and sensation to her groin
Looking down at her belly, Twilight stopped the ball's expansion
She looked slightly pregnant, which was just what she wanted.
She lay down on her back, massaging one hoof over her bulging belly, and continuing to rub her clit with the other
"Oh," she cooed aloud, "I am going to be the best mother ever; I've read all the books, I—"
She cut herself off as she hit *just* the right spot in her marehood, causing her to make a face and cease all thought.
She giggled to herself as she regained her senses, and drew both hooves to her breasts.
"Now where was I?" she asked herself coyly as she absentmindedly tickled her breasts.
Her horn glowed as she expanded the ball further.
Her womb swelled, and she soon lost sight of her breasts.
As her belly ballooned, she found her hooves could no longer reach her nipples, but she was too aroused to care.
As more and more of the library disappeared behind her belly, Twilight simply lay back and enjoyed the pressure.
Her womb pressed into her vital organs, and pushed blood out of them, moving more and more to her vagina, leaving her loins in a perpetual state of vague pleasure.
She stopped expanding the ball for a moment, and ran dried her wet hooves off on her burgeoning belly.
She looked like a mare ready to give birth, and she loved the way she looked.
"I *am* going to be the best mother ever," she said, a plan forming in her mind.
She grinned mischievously, and shifted onto her side.
She got up slowly, treating her bloated belly gingerly, and her head swimming from the pleasant glow in her pussy.
Twilight took slow steps to the stairs, her marehood happily throbbing with each step.
As she began to ascend, she noticed her belly lightly dragging on the lower steps.
Smiling to herself, she completed her ascent, and magicked her wardrobe open.
Sparse though it was, being friends with the most generous fashionista in Equestria had its advantages.
She levitated socks and a dress saddle out, and gingerly put them on.
The saddle was strapped right at the biggest part of her belly, which squeezed it in *just* the right way.
Looking at herself in the mirror, Twilight found her form attractive.
She was no narcissist, and didn't find herself attractive, but when her belly ballooned out, she couldn't help but be aroused at the very sight of herself.
Judging herself quite well-prepared, she gently teleported herself to Manehattan; she was too well-known in Ponyville and Canterlot to find a root there, and besides, the Big Apple always had the most chic stallions.
She stepped out of the alley and onto the busy street, stifling a smile as she noticed all the stallions (and a good portion of the mares) eyeing her with surprise and lust.
One stallion in particular, an extremely handsome red pegasus, stood out to her.
She shot him the bedroom eyes, and he understood at once.
A few minutes later they were in his apartment.
Small, bare, but cozy. He had a bed; that's all she needed.
They hadn't said a word to each other before he took her saddle off with his teeth.
He hugged her belly tight, making Twilight moan, and then released, moving down to her pussy.
His tongue darted up, down, left, right, going everywhere besides where Twilight wanted it to go.
She gently squeezed his head between her thighs, pushing him between her legs and her belly.
He looked up at her and read on her face that she he should try something different.
He sheepishly arched himself over her, his face inches from hers.
He gave her a soft kiss on the lips as he teased her with his cock.
"Put it in," she whispered in his ear.
He did so, and the pressure between her belly and the stallion's member was so great that Twilight came immediately.
She didn't stop, though; she came repeatedly from the time he entered until the time he finished.
She couldn't even muster the presence of mind to scream; instead, she simply rubbed her massive belly and melted in bliss.
Afterwards, the panting stallion cradled her belly and looked into her eyes.
"When are you due?" he asked.
"Yesterday," Twilight lied quietly.
He snickered and held her tight.
After a few minutes of respite, Twilight's horniness overcame her fatigue and she began to grind her full-term belly against the stallion's chest.
As she moved, her pussy throbbed as her belly pressed down against it, and the counter pressure from the stallions body put squeezed it tight.
She began to moan as the stallion took the hint and put his hoof on her pussy, pushing it towards her belly.
She silently thanked him with a stroke of her wing, but her other hoof was occupied, holding her belly.
She pushed the stallion onto his back and rolled on top of him, knocking the wind out of him.
The surprised pegasus regained his senses, and had recovered enough to insert himself.
Twilight squeezed his shaft and rubbed her belly as she moved up and down.
"Oh, OH!" she squealed as she found the angle in which her g-spot was right between her belly and his member.
Only a thin layer of nerves and flesh separated his cock from the ping pong ball which he assumed to be her child.
The stallion helped her by pumping, and moved his hooves up to her belly to rub the underside.
"Oh my g—aahhhhh," Twilight whined as she began to climax. "Oh, the baby, the baby, the baby," she intoned out of habit and fantasy.
Lucky for Twilight, the stallion wasn't able to stop himself. He finished only just after she did.
His concern and realization came just after.
"Are you... Are you ok?" he asked.
"Yes," Twilight said, collecting herself and falling back on the bed.
She stroked her tummy and cooed; she had all weekend. If everything went the way she wanted to, she might end up a real mother.
She left the stallion next morning after having gone at it the entire night. She looked 10 months with twins with the amount of semen in her.
