Olivano Olivano drew this wonderful sequence as a surprise! I wrote a story to go with it. This is part 1

"Gosh you're cute! You're all mine now, and you're coming home with me."

The toy was cute, sitting on her shelf. Rukia's new little donkey plush sat innocently, staring back at her with beady little button eyes. It had odd colors for a donkey, white with black splotches on its flank and ears, but that just added to its curiosity. Maybe she could give it a name sometime, but the last minute purchase had to wait for a title until tomorrow. The day had been long and exhausting and it was time for bed.. the soul reaper let her eyes close, thinking nothing of the unassuming plush she was now the proud owner of..

When the night was dark, however, things changed. Her new toy wasn't as restful as she was, which would have been apparent to anyone watching it climb out of her grasp and stumble its way to her backside. It unevenly, floppily tucked its knitted hooves underneath her waistband, jerking back to pull them down and expose her bare rump. Rukia would soon regret buying and taking home that new donkey toy as it climbed its clumsy way up onto her, mounting her, staring at her sleeping face with a grin.

A moment later and the donkey had grown a new set of equipment between its - now his - hindquarters. A hefty latex set of jackass bits, shining in the dim light. His new cock pushed its way into her rear, spreading her wide open around its rubbery girth, slipping in as if it were coated with thick lubricant. "Hhhfff!" It grunted, hips making contact with her rump, which had started to swell as he got to work. The little plush began to pump into her, hard donkey shaft throbbing, median ring catching at her tight hole with every stroke while Rukia slept through her changes.

The donkey, Kiba, changed along with his victim. Swelling and shifting from stitched fabric to flesh and blood and fur, that same fur growing along Rukia's bare flesh, her hands fusing together into hooves, elbows and hips cracking and reshaping into a new posture more fit for a feral beast like her soon-to-be-master. Rukia's increasingly equine face stretched out across her pillow, nose pushing away from her cheeks and eyes, mouth following with it to join in her new snout. Teeth became big square chompers, her ears growing long and fuzzy, swishing back and forth as she slept through the noisy, steady humping her former toy was delivering.

Squelch, schlorp, plap, plap plap, plap, plap... Kiba didn't for a minute stop humping her growing, increasingly furry rear. A tail had begun to grow above her plumpened cheeks, her hole puffing around his rubber - though lessening so - shaft, wide and thick almost like a donut. Kiba himself kept changing, more and more fur overtaking what was once felt and fabric, his latex genitals now leather, covered in sweat. "Hnnf.. hnnf.. hnff.. hnff.." His panting didn't wake the heavily sleeping donkey girl before him. Not even the last change to overtake her would be able to rouse her...

Rukia's own groin was finally caught up in the changes. Labia melted together into a scrotum, ovaries changed and descended down as testicles, clitoris lengthened and swelled massively, longer and longer, thicker and thicker, throbbing as it became a donkey's shaft! Satisfied, the donkey's tail swished back and forth as he spoke. "Wake up, my pet."

Rukia's eyes slowly opened. She felt odd... her clothes were in tatters around her.. something tasted salty. Rukia blinked several times to clear her vision, finding herself licking... something?? It felt so good! What was this? How could she feel through it? Who was breathing down her neck? Wait... WHAT!?

"Oh, this is just the beginning."
Oh no, there was someone-!
"HeeeEEEEEEHAAAAAAAAWWWWWWWwwwww!"
Rukia yelped in shock, the sudden braying noise having come from just above her. Before she could turn and look, and just as the bray was ending, she came to a powerful, sudden, and unexpected orgasm!

"MMMMmmmmpghm!!" Squealed the new donkey, her face splattered with her own orgasmic mess! Cum gushed from her new shaft, spraying her own face down in thick donkey spunk. "Haaaaahhhnn!" She moaned, the orgasm too distracting for her to confront the stranger standing right on top of her. "Wh... what... is... th-this...?" Her voice came in panting moans, energy wiped out from the strength of her climax. "A-... A penis!? Did I just-!?"

"Yes. Yes you did." Said the voice, causing her to finally turn her head and look up into the eyes of-... her plush? But he was... real now??

"What are you!?" Rukia lept to grab a weapon but her hooves uselessly clunked into the door of her wardrobe bed. "What's happening!? I can't-"

"No you can't. You're all mine, now, and you're coming home with me!"
