Kate

"I'll share a room with Kate," Ally said. "It's been awhile since I've seen her. I wouldn't mind catching up a little."

"Aww, okay," Jenny said. She gave Ally a quick, curt hug before heading towards her guest bedroom. Kate, on the other hand, looked Ally up and down with an emotion Ally couldn't place. Suspicion? Surprise?

"Obviously, we're going to take the master bedroom," Kate announced to her, allowing Danny to hear as he followed Jenny off and away. "I know you want to stay in your old room, but that's nonsense."

"Kate..." Ally complained.

"I won't hear any more of it," Kate said. "This isn't a fun vacation, right? You said that Grandpa said this was a challenge. We need an appropriate base of operations if we're going to win the deed to the house."

"I didn't realize you cared this much," Ally said.

"I loved Grandpa too," Kate said. Her voice ached with some small sadness, the hint of a tear underpinning her words. Ally hadn't thought much about being Grandpa's favorite -- she hadn't thought that it could hurt Kate's feelings. It wasn't Ally's fault that she was their grandfather's favorite. Maybe Grandpa couldn't help it either.

Still, Ally felt her own heart softening towards Kate. Maybe she would be able to find a way to make it up to her, over the course of their stay.

The master bedroom was larger than Ally remembered, which was odd to her. She thought things were supposed to look smaller as you aged; but even though the last time she saw the room was when she was a child, the room seemed twice the size it had when she was little. The floor was entirely covered in this deep, navy carpet, dotted with little flashes of white to mimic an expansive night sky. The bed itself was large enough to comfortably fit ten, its own surface covered in blue and white sheets. Off to the side was the en suite bathroom, a room twice the size of any guest bedroom, filled with a stoney sauna and multiple, lengthy ceramic tubs.

Ally couldn't help but think the entire place was designed to suit some gigantic, lustful orgy... She looked over at Kate, who, based on the strange, disgusted look in her eyes, seemed to be thinking the same thing. Ally didn't think it was all that disgusting... but maybe it wouldn't do well to say that to Kate. She hadn't imagined her sister prudish -- she'd met a dozen of Kate's boyfriends over the years. Ally always thought that she herself was the virginal one.

"We'll take turns in the bathroom, then," Kate said. "I'll go first. Check out the rest of the room. I don't really trust it."

"You always were such a worrier," Ally said. Finally, Kate smiled at her. They didn't have many touchstones as sisters, but that phrase was definitely one of them -- a joke they shared as kids. Between the two of them, they never stopped worrying, and they never stopped complaining to each other about how much they worried.

"Check the closets," Kate said.

##

It turns out, checking the closets had been a fantastic idea. Amidst a variety of old and beautiful dresses owned by her grandmother, she found a gorgeous ballgown, one that she recalled from her childhood and had loved even as a kid. It was a dress woven with strands of black and red, with small golden stars inlaid across the chest -- a dress Ally had always hoped to grow into, but now knew she never would. She brushed a hand across the dress's bust, lost in a fantasy of dancing in one of Scream House's many wonderful ballrooms... and her hand caught on a small piece of roughness. Ally dug her fingers into the dress and pulled out a small black envelope, just like the one that had appeared on her pillow.

Her fingers deftly opened the envelope, her mind racing with her grandfather's words, how he would leave her and her alone some tools to help her win the house. Her eyes scanned the letter as her heart raced:

To aid those of my family, read these words aloud: Fallum Moisses Egerex

Ally paused. Should she just say the words, uncritically? Should she ask Kate? The letter did say "those of my family," which meant the power might extend beyond Ally alone...

"Fallum Moisses Egerex!"Ally shouted, as though casting a spell, and maybe she was. For a moment, nothing at all happened. She waited, teeth pressing over her lip, to see the consequence of her action... And then she felt it: A small tightness pressing against her thigh. What on Earth...

She pushed down the hem of her pants, a small pain pushing out from between her legs, until she saw a new appendage rising from where her cunt used to be. Her eyes widened. The sleek, smooth foreskin of her penis stared back at her, while her hands moved to hold her new length. Even just touching it send small shocks of pleasure up her cock, the sensation rising above her stomach and fluttering inside her chest. She rubbed a finger across her sensitive cockhead, unable to keep herself from moaning, as her other hand lowered to her new, growing nutsack, tickling her scrotum with a strange, new pleasure. What on earth was going on... and why was it so... hot? Her breath became labored, she felt herself sweating. Her hand pulled back the skin of her cock and pressed it forward, awkwardly, figuring out the pleasure of her new length... She felt to her knees so as not to have to hold herself up, her hand increasing its pace, her body rubbing against the soft carpet of the floor...

"OH MY GOD!" A scream called from the bathroom. Kate's voice. "WHAT HAPPENED?"

The scream shocked Ally out of her pleasure, as she ran back into the master bedroom, where Kate had pushed open the bathroom door and run into the room, still fully nude. When they saw each other, they both froze. Their eyes fixed at each other's waists. Where each one had grown a full, throbbing cock, dripping beneath each other's eyes with a small trail of precum.

"What do we do?" Kate asked, misery coloring her voice. "What happened to us?"
