Trixiejack (breast absorption) (oh jesus christ you guys)

Applejack grit her teeth when she heard the arrogant showmare entering the barn, but refused to turn around and regard her. "Ah know what you're here fer, Trixie. And you can forget it. Never again."

Trixie's soft, haughty laugh spoke her opinion on the matter clearly. "Trixie seems to remember that's what you said last time, Applejack. And the time before that, too. What's wrong, hmm? Ashamed of how much you love serving your mistress?"

Applejack's face flushed hot with anger at the words, even as her slit flushed hot with something else. "Ah said, I ain't interested! Ah'm not gonna be your... p, plaything again! Now ya'll can just go on an' git!" With her back still turned - Applejack wasn't sure she could meet Trixie's eyes - she felt more than saw the unicorn's approach, stopping just behind her wordlessly. Some small, hungry part of the farm mare longed to press herself back into Trixie's embrace, to yield her very self before her better and accept her role as little more than a pair of milk jugs for Trixie's pleasure; it wouldn't have been the first time Applejack had surrendered to that temptation. But the cowpony's more rational, prideful side insisted, this time. Stay strong! Resist the temptation!

A long, silent moment passed between the two. Finally, seeming disinterested, Trixie turned away and began to leave. "As you wish."

Applejack's heart skipped a beat. "W, what?"

Trixie continued her leisurely stroll away. "Just what Trixie said. If you don't want it, I won't give it to you. I'll never make you mine again. After all, that's what you want, right?"

Applejack stammered - this wasn't how it had ever gone before! "But-!" That... wasn't fair! No, wait, what was she thinking? This was exactly what she'd intended! So... why did she feel so confused?

Trixie looked back over her shoulder, her intense purple eyes locking with Applejack's own. "Something wrong, my little farm pony?" Turning around to face the cowpony fully, she stepped in close. "Is there something you need from Trixie?"

"... Please." Applejack whispered, hating herself for it.

"Please... what?" Replied the showmare, doing an excellent job looking legitimately confused. "If there is something you want the Great and Powerful Trixie to do, you need to ask clearly."

There was another long, awkward silence before Applejack spoke once more, her voice low. "... Take me into you."

Trixie batted her eyelashes in mock surprise. "Why Applejack... I'm not sure what you mean. Could you elaborate? I want to make sure I understand you properly."

"Cast the spell again!" Applejack cried, the dam bursting inside her in a mix of shame, relief, and potent desire. "Let me be part of you again! Make me your milk factory! Let me be your tits!"

Trixie looked at Applejack appraisingly. “... And why should Trixie do this for you, hmm?”

“B... B'cuz...” Applejack trembled as she spoke the words. But she knew what Trixie would want to hear, and she knew what the all-consuming NEED she felt demanded. “It's where a pony like me belongs. Ah need ir so bad... please, Mistress...”

Trixie smirked in triumph. “Well, since you asked so nicely, my little pony. Never let it be said that the Great and Powerful Trixie is not generous.” Her horn lit up with a soft glow. Almost immediately, Applejack felt her body begin to tingle. She floated through the air towards her mistress, held aloft in a telekinetic field. Rearing up on her hind legs, Trixie spread her arms wide to greet the earth pony, as if a lover seeking a hug.

It was of course a perverse mockery of such an action, Trixie merely aiding the spell along as it delivered Applejack into her waiting grasp. The farm pony's heart began to beat like a drum in thrilled anticipation, her slit burning powerfully with need as Trixie wrapped her forelegs around the earth pony, pulling Aplejack to her breast. The unicorn's body was warm and soft, and the submissive earth mare sighed with relief. Her head met Trixie's chest as the showmare drew her into a tight embrace, and Applejack pressed her body as firmly as she could against Trixie's entoxicating body.

And so, the absorption began.

Applejack did not know if Trixie controlled the pace of the spell or not – but it would not surprise her if she ever learned that the unicorn simply preferred taking her time with this part. It was always slow at first, the warmth of Trixie's body gradually increasing, her embrace getting softer, and softer, and warmer as time went on. The transformation spell, now well on its way, had thoroughly sunk into Applejack as well. She felt her entire body shifting, flowing, become more loose and relaxed. Every nerve ending hummed with pleasure in an exquisite massage as the flesh of the two ponies began to flow together. Had Applejack been coherent enough to look up at Trixie's face, she might have seen the other pony's face biting her lip, cheeks flush with pleasure of her own.

But she was not, far too busy with sensations of her own as body slowly, smoothly stretched and shifted into a softer, rounder shape, adhering, bonding, becoming one with Trixie. The unicorn screamed in sudden, intense orgasm as her nervous system finally accepted Applejack's generous donation, consumed with not only her own pleasure but also feeling that of the farm pony, already joined with her mistress. She fell to the ground, twitching and heaving periodically as the spell completed its wonderful, wonderful task.

When the last of the tingles finally faded, Trixie sat up and admired her work.

Of Applejack, no trace could be seen – save, of course, the massive orange breasts that now adorned Trixie's chest. The jugs were obscenely big, testament to the exceptional vitality that Applejack possessed, and which Trixie now possessed as well. She laughed in exhiliration as she easily stood despite her newfound size. Applejack's strength was exceptional, and as a part of Trixie, it insured the unicorn's was as well. Experimentally, Trixie reared up, kicking the back wall of the barn and blasting a decent-sized hole right through. With stolen earth pony essence of one of the strongest mares alive running through her veins, the task was trivially easy, and she laughed at the heady sensation of her own power.

She spoke aloud, knowing that even in her present state, Applejack would hear her. “Ah, yes... so much better this way, don't you think, Applejack? I could make such better use of your strength than you ever could. And of course...” She breathed in deeply, admiring the way her enormous, soft, bouncy tits heaved with the inhalation, “... you look so much better this way.”

Trixie's breasts quivered at the words, Applejack's consciousness firmly embedded in the plentiful orbs.  With a small spurt, a dribble of milk escaped them. Trixie's new breasts were, of course, swollen with milk, so much so that she was aware of the pressure even simply standing there. Giggling at the sight, Trixie shook her chest back and forth, sending droplets scattering across the floor as her impressive rack swung back and forth with her movements. Deep inside of herself, she could feel more than hear Applejack moaning in pleasure as her essence liberally decorated the floor.

It was good – but not nearly enough. Eyes sparkling in dominant joy, Trixie's brought back hooves down to her chest and squeezed powerfully. Her chest lit up with sensation, every nerve seared by fire and begging for more, milk now spraying from her nipples in long, powerful jets rather than gentle sprinkles. The smell of Trixie's arousal lent a subtle addition to the overwhelming scent of fresh pony milk, Trixie's horn coming alive and working furiously at her clit with magic as she took now to slapping first one breast, then the other, back and forth, the perky orbs rippling under the impact and bouncing up against each other wonderfully, milk spurting from them all the while.

“This... 's all you're good for...” The unicorn panted through her pleasure, the faint pain of her powerful slaps completely overridden by the pleasure they brought. “Just... just my big, lewd titflesh, spraying milk everywhere... Maybe I'll... take some with me... give it to all your friends... They'll... like you better... this way... too!”

She was close now. So close. Applejack was too; the pain and the humiliation and the pleasure racing through her sensitive teats more than enough to make that abundantly clear even despite the earth pony's diminished state. Just then, it occurred to her, and she dimly wondered why she had ever been dumb enough not to try this before.

Wrapping both hooves around the bottoms of her tits, Trixie lifted them up to her mouth in tandem, took her nipples into her mouth, and sucked hard at the warm, gushing flesh. She gulped greedily, shot after shot of sweet ambrosia racing down her throat.

Her world disappeared in screaming orgasm.

When she came to, the first thing she noticed was the orange earth pony on the ground next to her, still unconscious from the pair's shared exertions – the spell was of course much harder on the subject than the caster. Lifting herself gingerly to her feet, Trixie groaned – her entire body felt sore, Applejack's physical prowess no longer fueling her own. Suddenly desiring little more than a bed to fall into, Trixie left quietly, not wishing to deal with the awkwardness that would surely ensue if Applejack awoke while she was still there. She'd had her fun with the farm pony as usual, but best not to get too involved.

Still...

Sighing to herself, the showmare stepped briefly back into the old barn before once more darting out into the night. When Applejack awoke, later, she would wonder where the blanket and glass of water had come from.
