Zoe didn't even look up from her phone. "What? Did you forget something else?" she asked, her voice dripping with teenage annoyance.
"Not at all," Jon purred, enjoying the sound of his new, husky voice.
Zoe glanced up, her expression shifting to confusion at her sister's tone. She took in the vision standing in her doorway—the same stunningly beautiful sister she'd always had, but now carrying herself with a predatory confidence that was entirely new. "What's with the weird voice? And what is that thing?" she asked, nodding towards the remote in Jon's hand.
Jon's grin was a wicked, beautiful thing. "I just decided we're going to have some fun." He raised the remote. "Starting with you."
"What are you talking ab—"
Click.
In a silent, instantaneous flash, Zoe's baggy t-shirt became a tight black vinyl corset, pushing her breasts up. Jon watched, thrilled, as Zoe's sentence hitched. She blinked, her reality seamlessly rewritten.
"—out?" she finished, her brow furrowed. She gave a little adjustment to the top of her new corset, a casual gesture. "Seriously, Jen, what is your deal? You're staring."
Jon's grin widened. It worked perfectly. He pressed the button again.
Click.
Zoe's cargo pants dissolved, reforming into a short, pleated black skirt and thigh-high fishnet stockings. She was in the middle of turning back to her phone, but paused, distracted again by Jon's intense gaze. "Are you just going to stand there and gawk, or did you actually want something? It's just a skirt."
He was drunk on the feeling. He raised the remote and clicked it twice in quick succession.
Click. Click. Click.
He watched as Zoe's breasts swelled to fill the corset, straining against the vinyl. Her hips and ass flared outwards, her body inflating into a perfect D-cup hourglass figure.
From Zoe's perspective, nothing had happened, but her sister's eyes had just widened, his smile becoming something hungry and unhinged. Her own body suddenly felt very warm and heavy for reasons she couldn't explain.
"Okay, you're officially creeping me out," Zoe said, shifting uncomfortably. She couldn't look away from her sister. Why did her parents have to give her a sister who was so hot?
A slow, powerful smile spread across Jon's face. He understood now. He could rebuild her piece by piece, and she'd never even know. The power of it was intoxicating, sending a fresh wave of arousal washing through him.
"Don't worry," Jon whispered, the promise in his voice making Zoe shiver. "You'll understand soon enough."
He took a step forward, and Zoe found she couldn't move, her body flushing with a confusing heat as her always-beautiful, but now terrifyingly intense, sister closed the distance between them. He absently set down the remote on her desk.
Despite being a good bit shorter than her, Jon pulled Zoe into her, their pert breasts pressing against each other as Jon kissed her. For barely a moment, Zoe squirmed but quickly melted into the kiss. Jon found himself to be surprisingly good at it (did the remote change more than just his body?)
Jon moaned into Zoe’s mouth as she kissed back, but then as quickly as it started it it was over.
“What the fuck are you doing?” Zoe asked, breathing heavily and flushed, but there was anger in her voice.
“I just wanted to kiss you, I couldn’t wait any longer.”
“Wait?!” Zoe practically yelled, and Jon winced. “If you leave right now, I won’t tell Mom this happened," she said, voice shaking, her eyes traitorously tracing Jon's curves.
Jon frowned and reached over and pressed PLUS. Zoe’s eyes fluttered, and then she blinked. Nothing outwardly about her had changed.
“I-I don’t think we should be doing this, Jen,” Zoe said, worried, looking slightly down at Jon's tits, her voice shaking. Jon shut her up and pulled her in for another kiss, pawing at Zoe’s breasts, drawing a moan from her.
“Admit it,” Jon gasped between shallow breaths.
“What?”
“You’ve always wanted me, you’ve always been looking at me when you thought I wasn’t looking,” Jon said, kissing along her throat. Zoe moaned as he freed one of her D cups from her corset.
“Oh god, yes.”
Somehow, they tumbled into Zoe's bed and pressed his face under her skirt and between her thick thighs. It didn’t take much to tear away the lace and press his lips around Zoe’s hot slit.
“Oh, Jen,” Zoe gasped, pawing at Jon’s shoulders. He got to work, teasing around the sides of it, delighting in her tiny twitches in response until he could take it no longer and took a long lick up her cunt.
It tasted heavenly, and Zoe thrashed beneath him. God, he couldn’t get enough.
