Principal Celestia spices up her wife's birthday...by allowing herself to be shrunk down and placed on her little sister's nipple.

Some people give their spouse chocolates for their birthday.

Some take their significant others out for dinner and a movie.

And some allow their sister-in-law to shrink them down to half an inch tall to spice up their wife's traditional birthday threesome.

Guess which category Principal Celestia falls into?

Tiny on Titan's Tits

Author's Note

I am totally going to hell for this.

Tiny on Titan's Tits

In her office, blinds drawn and door locked, Principal-Goddess Celestia indulges herself.

Wearing only a pair of black, lacy panties, she scoops up a handful of flea-sized tinies, leans back in her office chair, and sprinkles them like glitter over herself. Some of the shrunken humans pelted onto her bare breasts, gently landing on the gelatinous mountains. Some bounced on the smoothness of her belly.

The luckiest ones, however, have a special treat in store.

The principal stretches out the waistband of her panties and drops them inside, feeling them kick and flail. Some become tangled in the wiry forest of her pink, luminescent, pubic hair. Others land right in front of the pulsing, feminine cave, mashed into the warm hold below by white pillar that was her finger. Luckier still are thoseslid down the silky slope, bounced and tossed between her bubbly cheeks.

Her subjects writhe and wriggle all over her skin. Licking her taste with their tiny tongues. Nibbling it with miniscule teeth. Smiling, she snakes a hand between her legs...

Just as Princess Celly’s daydream was getting good, a teeth-rattling yawn echoed from the heavens. The silky, soft skin beneath her wobbled and jiggled. The principal-turned-princess returned to reality, straddling her arms and legs around her sister’s nipple, digging her white hands into the wrinkled, blueberry nub although trying to strangle it.

She wasn't sure if she wasn’t still daydreaming.

Ever since that incident at the Fall Formal, the past five years had felt like a crazy fever dream; the statue in front of the school revealing to be a portal to another universe; sea monsters in human skin that hypnotized people with music; magical artifacts erasing people’s memories; and so on.

And that was before Sunset introduced to her horsey doppelganger. Before she became the Co-ruler of a kingdom of talking ponies, where the sun and moon had to be raised and lowered manually.

It felt like her life couldn’t get any stranger.

Once the breast-quake settled down, Celly laid back against the areola, her nude body a stark contrast to the dark blue skin.

She should have known better.

From her nipply perch, Celly looked over the delicious bodyscape of her sister.

At this size, her little sis was more landscape than sibling. The reclining body was a pale blue hillside, covered in soft curves, mounds, and valleys. Her stomach perfectly shaped with only the slightest covering of fat for cushioning. And her ass. Sweet goddess her ass! Even at normal size, it’d been perfect. But here, it truly was the ass of a goddess; heart-shaped with a perfect balance of chub and muscle.

Had her sister been a real giantess back home, entire religions would’ve formed around that perfect butt. She couldn’t help but giggle; all hail the mighty Daht’ass!

“Enjoying the view, pet?”

Celly jumped, losing her grip on the nipple and tumbling over the edge before barely managing to cling onto the lip of the puckered milk duct.

“Let me help you with that..” Two fingers the length of tennis courts descended from the sky, gently plucking her from her precarious perch and setting her back onto the nipple. After taking a few moments to calm herself down, Celly looked up to see the living cliff of her sister’s face staring down at her like a goddess.

“My apologies, little one. I did not mean to startle you.”

Someone’s getting into character, Celly mused, ears tingling as the Drink and Shrink potion automatically modulated her sister’s voice to something that wouldn’t annihilate her eardrums. Fresh, minty gales blew across the nipple with every word, raising goosebumps across Celly’s bare skin. Shivering, she raised her hand. Her palms lit up with a soft golden light followed by a pleasant chiming sound. A weak magical shield popped up around her, deflecting the worst of the gale.

Being spiritually bonded to a magical pony princess had its perks.

“It’s alright, Lulu,” Celly yelled up to her goddess-sister, cupping her hands around her mouth.

The cliff frowned. “What was that, little pet?”

Celly rolled her eyes. “I said: I am fine, oh great and mighty moon goddess.”

“That’s better.” Lulu nodded. ”Now, would you prefer it if I made you a few inches taller?”

“No thanks, my goddess.” Celly shook her head and tried again. “Tia—I mean, Goddess Tia likes her pets as little as possible.”

It’s what she would have wanted, had their roles and their size been reversed. And since Tia was literally just a horsier version of herself...

“Goddess?”

“Yes, pet?”

“Just how did Luna learn about...my fetish?” This crazy spin on their traditional birthday threesome had been her sister-in law’s idea, after all. She had to have known somehow.

Goddess Lulu smiled. “Do you remember last week’s girls’ night out with Luna and I?”

“Oh, that.” Celly groaned. The hangover had axed her skull.

“After a few drinks, you began began babbling about how you enjoyed being in control, both in and out of the bedroom. That was when you told us about your...fantasy. In rather explicit detail I might add.”

Celly facepalmed. Note to self: never drink again. Ever.

‘Look at it this way, pet.” A finger descended to the nipple. Celly flipped herself over and let the deity-sized digit stroke her back. “Not only did you bond with my marefriend and I, but you also gave her an idea for the best birthday present ever. Tis a shame she could not join us tonight, what with Night Court but duty calls..”

“Mmm... “ Celly purred as the tiny ridges rubbed against her back. The scent of soap, sweat, and musk filled her nostrils. Pleasant warmth boiled in her loins. Tia had given her companionship, a kingdom, and the chance to live out every little girl’s dream come true; if any being deserved a good birthday present, it was her.

The finger continued stroking, stoking the fires within from a blaze to an inferno. Celly nuzzled her sister’s plush areola, nibbling on the soft flesh, kissing it. Worshipping it. Liquid leaked from her nethers—anointing the nipple

A Lulu-shaking groan reverberated through the bodyscape. A hand started teasing and twisting the nipple across from Celly. “Mmm… look at you, so tiny, so cute against our giantess tits.”

Celly suddenly found herself pinched between two fingers and rudely dumped into the valley between her sister’s breasts. Before she could react, the walls of the valley slammed into her, breast-flesh molding around with a feeling like being pressed into warm dough.She could hear the muffled moans of her sister.

“Do you enjoy this, little pet? Do you enjoy being mashed between our fertile mounds?” Lulu groaned again, rubbing her tits together Droplets of sweat the size of watermelons slid down Lulu’s mounds. “Maybe we should shrink you down even further, small as a dust mite. You could live on my nipple, exploring its creases, sleeping inside my milk duct.” she said, followed by another Lulu-shaking moan.

Before Celly could respond, something twitched inside her head; a signal sent through her spiritual link. “Mmmm-mmmm!” She tried to yell from the mountain of breast flesh.

The breasts spread apart. “What was that, pet?”

“Tia’s coming!”

Without another word, Lulu reached down, plucked Celly from the Valley of Tits, and deposited her back on the nipple. This was it.

There was a series of muffled earthquakes. In the distance, obscured by the thick gloom that filled her bedroom, a slab-shaped blob on the horizon slowly swung with an ear-piercing squeak.

Note to self: have maintenance lubricate those hinges on the double.

A large, white blob walked out of the gloom, becoming clearer and clearer as it got closer. Celly smiled.

The birthday girl was finally here.
