(Fate Grand Order TF, M and F to Various)

BB sighed, looking at the three of us. “What to do with you… What to do…”

She’d already warped the rest of Chaldea, turning goddesses and heroes alike into whatever she’d desired. Currently she was lounging on a sofa that had once been Artoria, now only recognizable because of the blue trim beneath its golden cushions.

“You could go to hell,” Jalter scoffed. I took comfort in the fact that despite everything, she was still ready to fight. Even though there wasn’t much we could do against a Servant that had absorbed a Holy Grail.

Jeanne reached out a hand to caution her sister. She opened her mouth as if to say something, then stiffened. Neither Jalter nor I had time to react before Jeanne exploded, leaving only a fluttering dress drifting towards the ground.

It was so sudden. One second, she was one of the most recognizable saints in Human History. The next, she was just… Gone.

“What the hell did you d-” was as far as Jalter got before the same thing happened to her. Instead of a dress, though, a pair of long nylon leggings collapsed onto the tile.

“Oh, don’t give me that look. They’re fine. Well, as fine as your new outfit can be,” BB gestured towards the clothes, and I realized that neither of them were what the women had been wearing. Then the second half of her sentence registered, but by then it was already too late for me.

My body felt like it was being squeezed all over. My waist pinched in, my cheeks slimmed, my arms and legs drew long and slender. There was a softness to all of it, as well as a maddening pressure. I moaned as all the fat in my body drew towards my chest and hips, soft and heavy breasts swelling, to be counterbalanced by an enormous ass that jiggled every time I breathed.

That wasn’t all to it, though. My skin paled, and my hair grew past my eyebrows. I blinked repeatedly as the soft strands poked ay my eyes, but was still frozen fast in place. My new bangs looked lighter than they should have been though, a rich white instead of the usual deep black.

“You like? I knew she was your favorite, so I thought you might want to walk a mile in her shoes. Or… Well, a mile on her as nylons.” BB moved her hands like a puppet master, and I jerked in time with the motion.

The leggings were first. I could swear I felt them quiver in… Anger? Anticipation? It didn’t matter in the end, there wasn’t anything they could do from shoving my feminine feet into them one at a time, stretching the girl I had a crush on up to my changed thighs. My toes wiggled, not of my own volition, and I marveled at how soft she was.

The dress was next, a proper saint turned into a sexy nighttime affair. Her body was silky and soft and it clung to me like it was unwilling to let go. I swore I could feel heat radiating from it, like the dress was capable of blushing.

“Hmm… No, not quite…” BB sighed, waving her hand.

We fell onto the ground, human again for the moment. It looked like it wouldn’t last long, though. Jalter’s mouth was stretched around both of my feet, a shade of pink taking over her face. Jeanne was pressed against my back, but I could feel something wrong with her, too. She felt almost furry.

Come to think of it, I did too. Everything itched, especially my feet that were pressed against a slimy, soft, writhing thing. It felt as thick as an anaconda, but judging by the horrified look on her face, it was her own tongue.

“Yhuhgh bitfth,” she tried to snarl at BB, the effect lessened by my feet stuffing her mouth. Her drool soaked the hairs that were growing from my feet, and I could feel my new fur cling to what felt like bulging paw pads.

“What’s the matter? Something got your tongue?” BB twirled her finger, and Jalter gagged as her tongue snaked up my legs, wrapping around them, binding them together even as orange fur overtook them.

To her credit, Jalter tried to resist. She looked like she wanted to do something, anything to keep her from turning into a fat, dumpy Lickitung. But the more her tongue grew, the more her body shrank. Her slender form grew pudgier and pudgier, arms and legs shortening in time with the growth of a new, massive pink tail.

I wanted to say something to her, but coughed instead. It felt like hot spice stuck in my throat, and to my shock, a small gout of flame burst from past my lips. I turned from Jalter, afraid of scalding her, and found myself face-to-face with Jeanne. Or… Whatever she was becoming.

Her eyes were squeezed shut, and there was a familiar blue and cream fur covering her face. Her ears were triangular and pointed now, and twitched as I took in a raspy breath, ready to cough again. “Muuuhaster?” Her voice sounded low, dumb, guttural even.

Then she took my face in her hands, twisting me in a grip that was more powerful than I expected. Jalter was forced to thump into her side, letting out a sputtering, muffled gasp. Jeanne’s lips crashed against mine, and I coughed again.

I could feel the fire burn from my throat into her mouth, and felt a pang of worry for her. But instead of burning the changing girl’s mouth, it bulged her instead. It was like filling a balloon, each cough of mine swelling her a little more at a time.

“Hghnmmoooreeee,” she rumbled, growing, softening, pressing against me. Her breasts were big enough to stuff my entire body between, and I whimpered as she eagerly hugged me, wrapping her arms around me and turning again.

Jeanne’s dopey Snorlax body squished me beneath it, and she ground her blue-furred crotch against her sister’s Lickitung face. The muscles in my arms spasmed as I tried to push back against her, and-

“Not that either.”

I was human again, gasping for breath, looking up at BB pitifully. The saints gasped at my sides, and I turned towards Jalter in concern, only to freeze.

To my left was a massive white-furred Tibetan Mastiff, with big mindless brown eyes and a small ruff to the fur on her mane that looked almost like the little ahoge on her hair. I didn’t need to look at Jeanne to find out something similar had happened there, she was already pressing against me, her furry body so warm against my right side.

Too warm. I tried to pull away from her, but the Jalter-dog took this moment to press against my left side, sandwiching me between them. It was like being stuffed between a pair of heated blankets in the summer, and I started to sweat, overheating.

“What… What the hell are you doing now?” I gasped, starting to pant. As if it was answering my own question, my tongue bulged in my mouth, stretching my cheeks, pressing against my teeth. I couldn’t keep it in, I had to let the massive thing flop past my lips, feeling it wetly dangle below my chin as I started to pant. “Duuhhhhhawwgs?”

It wasn’t quite what I meant to say, but I could feel my thoughts slowing. What I couldn’t feel was my body below the neck. I looked to my shoulders, but instead of finding them, I could only see the canine heads of my former protectors.

“Not quite…” BB smirked. “Just the one dog, actually. My little take on a good boy.”

It took me an embarrassing amount of time to remember Cerberus existed. It took even less time to realize an even more embarrassing thing: there was one part of me I could still feel. Somehow, despite all of this, I was more aroused than I had ever been in my life.

The realization came in time with our bodies fully merging. The heat of their fur became all-encompassing as they fully squished me between them, their inwards legs sliding towards the center of our body, softening, jiggling their way into sensitive teats.

I could feel their minds too, both canine instinct and fading human intellect alike. Both the dogs were horny, so horny that Jalter’s white-furred head started to lap at our own tits, while Jeanne’s blonde-furred head dipped her wet nose against our crotch, sniffing at my dick.

They were ashamed, humiliated. I couldn’t quite feel more thought from them than their overwhelming emotions, enough to drive embarrassed tears to my eyes. “Puhuhuhleethe! Thtawp, ‘oooo tuuhoooo!” I tried to plead with them, and their embarrassment only grew.

Unfortunately, so did our arousal, too. Thick fur bloomed around my neck, leaving me hot and bothered in every sense of the phrase. Shame started to fade, and I started to lick Jalter’s jowled face next to me, feeling my own growing jowls brush against our fat teats.

At the same time, Jeanne shoved her entire maw over our reddening cock, loudly slurping at it, bumping her nose against our balls. Our hips started to pump, each of our heads puffing out quick, hot gasps of pleasure.

“Perfect. I think I’ll just leave it at that, then.” BB smirked. She reached down and rubbed behind my ears, stretching them longer, leaving me with a canine head. I dimly noticed that the tail between our legs was dark like my own hair. I wondered what we looked like.

Then our body tensed, hips spasming, pleasure whiting out the rest of the world.
