Sunlight streamed through the window, bathing Twilight's face in golden light. The lavender alicorn screwed her eyes shut against the glare of the morning sun. A groan escaped her lips and she buried her face in her pillow in a desperate attempt to escape the shimmering reams of fiery light that burst through the window.

A rainbow of colour literally flew through the window and landed in a heap on the hardwood floor of Twilight's house.

"Hey Twilight!"

"What's up Rainbow Crash?"

Tears sprang to the pegasus' eyes and she began to cry. "Why!"

Twilight immediately realized her mistake and she pulled the sky blue pegasus to her, desperately trying to ease the convulsions and tremors that ran through her.

"I'm sorry Rainbow Cr- Dash," she apologized. Can you forgive me? Please Dashie?"

Rainbow Dash scowled and said, "Alright. But only if you promise not to do it again."

"I promise."

"Thank you Twilight."

A weak smile found its way to the alicorn's lips. "No problem."

"You ready to play?" Enthusiasm laced her tone.

Twilight's face fell. "Sorry Dashie. I missed a load of studying yesterday when I was playing with you guys and I desperately need to catch up."

Rainbow nodded. "OK. I understand."

"You do? That's great!"

"I'm sorry you can't come and play with us, but maybe we can reschedule?"

"I'd like that."

Twilight smiled gently, and her horn glowed a soft magenta as she used her magic to lift a book from one of the high shelves and prop it open on the bed.

Another burst of colour and Rainbow Dash was gone in a instant, exiting the way she had come; through the window.

A sigh of content escaped Twilight's lips, and she continued to read, completely engrossed in the book that was open before her. Black met white as the words stood out on the faded parchment, clear as day to the lavender shaded alicorn.

A slight knock on the door caused Twilight to jerk her gaze towards the sound and yell, "Who is it?"

"It's Rarity," came a voice from the other side.

"Come in."

The door opened and in trotted the snow white mare, her coat glistening in the dim lamplight that filled the room. Walking over to stand beside Twilight, she said, "Is it true? What you said about… you know…"

Twilight sighed and said, "Yes Rarity. It's true."

A delighted smile leapt across her face and the alabaster unicorn squealed and placed a gentle hoof on the slightly distended bump of Twilight's stomach.

"I love you Twilight," she murmured softly.

"I know Rarity. I know."

Rarity leapt onto the bed and pinned Twilight down beneath her, plunging her velvet tongue into her mouth, letting it explore the moist cavern that was her lover's maw.

Excited by her actions, Twilight kissed her back, rolling over so that she was the one pinning down her lover. She deepened the kiss, letting her tongue find its own path, deeper into Rarity's mouth, her tongue wrestling with that of her lover, engaging in a passionate dance, a tango to which there was no end.

An excited moan was swept from the unicorn's lips, and she sneaked her hoof down towards Twilight's nether-regions, taking in the sweet smell of her dripping sex.

But no sooner had she reached it, the door swung open, and in walked Pinkie Pie, a delighted grin on her face.

The two lovers screamed and rolled off each other, glaring angrily at the pink earth pony as she continued to grin stupidly.

"Pinkie Pie!"

"Oops! I guess I came in at the wrong time huh? I'll just leave then."

"No, you might as well stay now that you're here."

"Oh. Okey dokey then."

Pinkie Pie laughed and dropped onto the bed, making the two lovers wince as the wooden frame creaked under the extra weight.

The moment Pinkie turned her back, Twilight and Rarity became locked in a passionate embrace once more, their lips sealed together as if glued with hot wax.

The earth pony twisted her body and sneaked a glance at the unicorn, who was running her hooves along the alicorn's shoulder blades, eliciting a quiet moan from the sex deprived, virgin mare.

Pinkie Pie blushed heavily and squealed in partial disgust, leaping from the bed and racing from the room faster than… well… Rainbow Dash.

The two mares, both unicorn and alicorn, laughed as the earth pony exited the room, then sighed in disappointment, knowing that their intimate moment was over.

"Well," sighed Twilight, "it was fun while it lasted."

"Aww, don't be like that," pouted Rarity. "We still have tomorrow."

"I guess."

"What have I told you about being downcast? What happened to the Twilight Sparkle I used to know, hmm?"

A shrug was her only reply.

That was it. This was enough.

Rarity trailed her hoof down towards Twilight's pregnant stomach, and ran it along the dark purple line left by the baby's constant growth inside her womb.

A gentle laugh escaped her throat and slowly turned into a fit of giggles as the alabaster unicorn began to tickle the alicorn's belly, even beginning to laugh a bit herself as she felt Twilight's baby move beneath her hooves, a soft smile tugging at the corners of her mouth.

"Beautiful, isn't it?" asked Twilight.

"Yeah. If the baby is, as you say, mine, then I will be happy to raise her with you."

"Her?"

"I don't like calling unborn babies 'it'. To me, it doesn't seem right. I mean, they might not be born, but they're still alive, and I'm sure you agree. Right Twilight?"

"Absolutely."

The unicorn mare edged slowly towards her lover, nuzzling her gently with her velvet nose, her soft blue eyes meeting with Twilight's shimmering purple ones. A gentle smile touched the corners of her mouth, her lips curving into a soft crescent shape as her happiness grew.

An exhausted yawn escaped Twilight's throat and Rarity in turn, yawned back. Glancing out of the window, Rarity noticed that the sun had begun to set and the pale light of Luna's moon was seeping slowly through the misted glass.

Pulling back on the edge of her duvet, the alicorn princess stepped in front of the window, the moon's light spilling over her form and illuminating her voluptuous curves. A seductive light sparkled in her violet pupils and she wanted desperately to run her hooves over her marefriends' body, to feel the alabaster unicorn's gentle touch glide smoothly over her-

"Twilight?"

She snapped out of her erotic reverie at the sound of Rarity's voice. "Yes?"

"You OK? You kind of… zoned out for a moment. I was getting worried."

"Yeah, I'm fine."

Then, she collapsed.

"Twilight!"

Rarity galloped over and picked her marefriend up in her front hooves, setting her gently on the bed and flicking back the other side of the duvet so that she could get in. Tracing her hoof along the sloping curve of Twilight's belly, she whispered softly into her ear, gentle, comforting words that sent the alicorn into a dreamlike stupor, her tired eyes drooping ever so slightly.

Climbing in beside her lover, the unicorn bearing the three diamonds upon her flank buried her snout in her lavender shaded neck, the soft hair driving her crazy as it rubbed against her face.

A soft grunt emanated from Twilight's side of the bed as she felt a gentle push on the inside if her stomach. She smiled in wonder; even though she'd already felt her baby move, to her, it was amazing just to feel even the slightest twitch of her growing child.

Grabbing Rarity's hoof, she placed it lightly on her belly and an amazed smile lit up the unicorn's face as she felt the little filly move.

"It's amazing," she murmured tiredly.

"Tired?"

"Yeah."

"Then let's get some sleep. We'll need it."

And with those words, the lavender alicorn and her lover both drifted slowly off to sleep in each other's arms.
