She nods and starts looking around. Clues? Any clues around here?

How about this handwritten note in red ink and sharply spiky cursive sitting on the bedside table next to the girls' obsolete glasses?

Hello, Ava and Pirates—

You're both likely rather confused at the moment. Allow me to explain what's going on, in as much as I can.

Yes, you've both been transformed into the most closest bodies to your ideals I can give you while still being somewhat superficially explicable to mortal science. You girls unknowingly did me a good turn some time back, and I make a point to pay my debts.

To explain in more detail, you're both fully functional, though sterile. You'll have the normal hormonal cycle, but modified to be bloodless since there's no need to keep refreshing uterine linings for a pregnancy that won't happen. Your eyesight is repaired and a bit upgraded, your metabolisms should be a bit more cooperative, and your flexibility enhanced. Ava, your knee and ankle are healed, as are your hearing damage and your tachycardia. Pirates, that bit of nerve damage in your finger is resolved, as is the glitch in the nerves around your right elbow that kept putting your fingers to sleep at certain angles, along with your shoulders and knees. Generally every instance of functional damage in either of you has been completely repaired. Scars have been left in place, however, because their disappearance would be harder to explain, and Hailey's attached to several of them. Balance and coordination is improved as best I can without involving any mental changes, and your aging has been permanently halted.

Furthermore, your sexual sensitivity has been increased, as has your libido and pain tolerance. You also both have easily suppressible gag reflexes now.

Have fun.

"Aaavaa? I think I found a clue." She holds the note out to her.

She reads the note.

Then she breaks out in giggles.

"Okay, my best bet now is that it's, like, Jade, or Nathan, or basically any other random trans person I ran into in my work as an online mod. I'm trackable down by mundane means I'd bet, and if magic is in the picture, it's probably even easier to find me. Someone who lived, or had a friend live, or something like that. I can think of dozens of people who'd want to give away transition magic if they had it, and I was a bit of a public figure for a while, so..." She rubs the back of her head. "So if that's Who, the What is — some kind of biohacking, pretty clearly, if they can make that detailed of changes and locate all my physical issues. Probably it doesn't extend to brain work, or maybe they just didn't want to maybe mess with my personality — I know I wouldn't like to wake up as a different person suddenly. For all that I have done exactly that more than a few times, it's different when it's by another's choice."

Sable stretches and grins. "So someone either or both of us looked after hit the magic jackpot and decided to throw us a sneaky upgrade as a thank you? Yeah, that's a pretty solid angle. The "unknowingly" bit makes me wonder a bit, but maybe the writer's just being cheeky. Who knows. Either way, this is a pretty decent explanation and we can probably celebrate."

"I'd guess it's someone we don't know by name. A friend of a friend. But that's wild guessing, and I think the note explains enough. Probably they want their privacy — I wouldn't want to be inundated with a thousand requests to trans strangers' gender either."

"Yep! Well, we'll just have to distract ourselves from speculating. However shall we do that, I wonder?"

She grins, then flips Ava onto her back and pins her, kissing her fiercely.

Ava lets out a little yelp —

And then dissolves in giggles and pulls Sable in harder atop her.

Sable presses in tightly against Ava, kissing her deeply, savoring the subtle squish as their bodies fit together in new ways. One hand drags down and cups Ava's right breast, squeezing it, learning the new size, and then pinches her nipple sharply in the way she knows she likes so much.

"Ah!" She's definitely more sensitive now than she was before, and feeling the press of her extra boobflesh makes her feel awake and alive. Joy surges through her as she starts to feel just what her new body can do. 

She nuzzles her face into Ava's neck, nipping and kissing teasingly, She gropes roughly, squishing and squeezing her breast, other hand slipping down to squeeze her ass. With a little shimmy, she shifts to the side and straddles Ava's left leg, pressing her own thigh up in against Ava's sex.

"Isn't this just lovely," she purrs.

Ava grins, and carefully sits up, pressing into Sable and shifting so she can grind in her thigh more firmly. "Yeah," she says with a teasing smile. "Come and get me, cutie." She leans in and presses her lips to Sable's, and traces a hand down her jaw and over her collarbones to nestle between her breasts. 

She presses in against Ava's hand, savoring the richness of the heightened sensitivity, and kisses her fiercely, hungrily, grinding her thigh in against her girlfriend's pussy. She pinches and twists her nipple, nips her lower lip, and growls into her mouth. Her right hand caresses up and down Ava's side and shoulder and neck, tracing the edges of Ava's changed body, savoring every inch.

Ava lets out a harsh sigh, and grinds back against Sable, feeling alien but oh-so-right sensations rush through her body. Her body presses in close and firm against Sable and she lets out a harsh sigh, her hands grabbing firm handfuls of Sable's breasts to grope and pinch and twist. 

"Sable," she moans softly. "Sable..."

She flushes and gasps at the sensitivity and rightness in all the richer sensations, the simple euphoria in having so much more breast to grope, the blissful relief from dysphoria mingling with the building arousal as these unfamiliar folds slide against her love's thigh.

"Ava," she moans back. "Oh fuck, this is amazing."

Her hands dig in and squeeze, feeling and teasing every inch.

"I love you," Ava says, and grinds in her thigh harder, her breath rising, taking possessive handfuls of Sable's body. "Mine, mine, mine..."

Sable whimpers and moans at Ava's possessive grasp, shuddering and pressing against her, murmuring back, "Yours, yours, yours," with every breath. She grinds against her and writhes atop her and kisses and bites.

Ava gives as good as she's getting, feeling bright and full of confidence in her new body and pushed forward on a wave of bright sweeping euphoria and pleasure. 

It feels so fucking good. Even just grinding her clit in feels like it clicks, like it's part of her, like she owns it. And she wants to own Sable as well. And every motion and grind is full of that possessive, greedy hunger. 

Sable's just as hungry, just as desperate to claim and be claimed. Her breath comes in panting growls — growls that sound cute now rather than too deep or harsh — as she crushes her body against Ava's, sensitive skin dragging against sensitive skin, every touch full of arousal and euphoria in equal measure.

"Ah, Sable —"

Ava has just as much of a hair trigger as before, it seems. She squirms a little against Sable, her eyes squeezing closed —

And then she pushes Sable back and rides her, grinding in hard, clearly seeking the edge of her own orgasm —

Sable's not far behind, pressing in and grinding just as desperately, her breath hot and ragged—

"Ava, Ava, Ava—"
