"A..Are you sure it'll..." Fluttershy whispered to the mare behind the door.

"Yes!" A white hoof reached out, holding a solitary jar of lotion, its sides shimmering in the dying summer sunlight. Hoof met hoof, money and product were exchanged, and Fluttershy went on her way, glancing about nervously, uncertain that she was unseen.

Arriving home, the pegasus slammed, then locked the door, proceeding to lock the back as well. Sighing in relief, and glancing about her home, she took out the gel she acquired that day. It was a soft cream colored paste, with a single ornate 'R' insignia on the front. Opening the bottle filled the room with a vanilla scent, warming Fluttershy's heart and home. A single dollop met hoof, and soon, the lotion was being worked into her limbs and sides. "Oh...I sure hope this work—Eep!" Fluttershy looked down in shock as her legs began to shrink and deflate, her body beginning to ripple in pleasure.

Falling to the floor, Fluttershy could only smile as the changes grew more frequent and interesting. Her legs had retracted into her body, leaving her limbless. Her head began to shrink, her mane merging into her head as her face elongated, and her mouth sealed over, pressing inwards to form a small indent. Her head grew less defined as her torso shrank into a short rod-like shape, taking on the color of a soft white. Her head followed suit, shrinking down and becoming proportionate with the rest of her body. As her body converted to rubber, she was thrown into a blinding orgasm, her senses overloading as her brain grew fuzzy. All she could think about was filling up a waiting mare—

'I'm almost finished...' Fluttershy thought, her form shrinking to around a foot and a half long. As she remembered what had happened, her mind faded to thoughts of being used, filling up her owner as the best dildo she could be.

A shadowy figure levitated the dildo off the floor, storing it away in a saddlebag. The pony left Fluttershy's house, retreating into the darkness.

"Oh..Oh Fluttershy!" Rarity moaned, her hips rocking in time with the dildo currently thrusting in and out of her. Fluttershy was in bliss, serving her owner as well as she could, the dildo moving faster and faster as Rarity grew more aroused. In and out, Rarity moved Fluttershy's sleek form into her folds, bringing her oh so close.

A small puddle began to form on Rarity's bedsheets, her haunches soaked with her juices as she climaxed, pressing Dildo-shy into her as hard as she could. Riding the waves of ecstasy, Rarity resumed moving the dildo back and forth, teasing her clit. With shocks of ecstatic bliss, Rarity forced Fluttershy's form through another rigorous workout. As she approached the peak once more, she felt a tingling sensation deep within her folds, as if the dildo were radiating magical energy.

Rarity paid it no mind, lost in her pleasure so deep, until the tingling became a zapping, and Fluttershy's head re-materialized inside Rarity's dripping sex.

"Aaaah! Ew! Ew!" Fluttershy's voice squeaked out, her body reforming outside of Rarity's folds, her neck reaching in like an oversized snake. As she tugged and squirmed, Rarity was thrown into a blinding sensory overload. She swore her hips were cracking, her clit was being smashed against Fluttershy's snout, and her walls were being tickled by millions of tiny hairs at once. She was in the deepest pit of Tartarus and the greenest pasture in Elysium at the same time, and she struggled to fight the immense pain working through her pleasure.

Fluttershy forced herself back, using her forehooves and wings for added power. As she slid back, inch by terrifying inch, the dark walls of Rarity's vagina covered her with juices, and writhed around, trying to clamp down on and expel the object at the same time. Rarity shrieked with pain and pleasure as Fluttershy forced her chin out, pulling with all her minimal strength. As her teeth began to catch air, she gulped down a breath of sweaty, musky stale air as though sipping from a desert oasis. She jolted as Rarity jerked about in pained bliss, her teeth clamping down on Rarity's lips and eliciting another deafening shriek.

Rarity panted. She had never experienced such a rush before! Her body was exploding in pain, and at the same time, it was like giving birth to a foal! She had always wanted a foal, and could pretend, for what it was worth, that Fluttershy's head was her foal. Taking on a motherly role, she began to force pressure around Fluttershy's head, easing it outward as her fur tickled Rarity, making her giggle drunkenly. As she rode the high from having her walls expand so large, she took pleasure in easing the head out of her folds, massaging around her lips with her hooves. As Fluttershy moved closer and closer to freeing her head, she jerked back, and with an audible pop, she shot out of Rarity and slid across the floor in a trail of Rarity's juices. Coming to a rest before the door to Rarity's bedroom, she looked up with weary eyes, smiled at Rarity, and with a whispered "Thank you...", she fainted.

Rarity fell back on her bed, panting, and gently rubbing her sore folds, easing the cramped muscles after the technical 'birth'. With a sigh, she looked over at the box on her floor containing hundreds of little lotion bottles, all with a fancy 'R' insignia. "It appears...that I will be sold out rather quickly." She looked about her room, and to the door, where a scared, wide-eyed Twilight stood, mouth agape and legs shaking. "Oh, well, hello darling." Rarity quipped.

"I heard...So much wrong with..." Twilight shook her head, unable to process the scene before her. She looked from Rarity, to the lotion, and back to Rarity. She tentatively opened her mouth.

"Does it come in strap-on?"

Author's Note

I had no idea what to tag this as, I went for so many different angles. Not really romance, but has the romance aspect.

Huh. Ah well, can always change it later.
