The Sleepover - Part 9

 

Billy stared at Fred, then back at the mask in his hands. He couldn't believe he was going to put it on again. Especially after what happened last time.

He hesitated.

But there was something in Fred’s expression, a glint of excitement that mirrored his own. Billy took a deep breath and pulled the mask over his head.

The transformation was immediate, a rush of sensation as his body filled out, the mask merging with his skin in a seamless wave. He felt himself change completely, faster even than last time. 

The voice was there, waiting.

“Ohhh, Billy...” Erica purred, “It’s so good to be back.”

His clothes were almost immediately too tight, his jeans cutting into his hips, his t-shirt pinching his chest as it swelled beneath the fabric. 

He looked at Fred, eyes wide, already feeling himself slip away.

Billy’s voice was breathy, “She’s... she’s...”

“Taking over?” Fred’s eyes were huge, filled with a wild mix of fear and excitement, “Just try and hang on!”

Billy wobbled to the bathroom, legs shaky and uncertain beneath him, “She’s so strong!”

He barely made it, the jeans binding him at every hurried step. He yanked at them, the seam bursting as they slid off his growing form.

The force of the transformation swept through him, and he could feel Erica surging, feel her trying to claim him.

Billy didn’t know how much longer he could fight it. 

Fred hovered in the doorway, unable to look away.

“Don’t let her win, Billy! You’ve got to resist!”

“Isn’t it amazing?” Erica’s voice filled his thoughts, powerful and seductive, “Isn’t it wonderful?”

But Billy found an opening, and he started to push back. He felt a flicker, like a flame catching in the wind, and held on with everything he had.

He writhed, feeling the woman’s body shifting, his boyish mind struggling to reassert itself, “I’m still...”

“Ohhh, Billy,” the voice breathed, caught between a sigh and a moan, “I don’t think you are...”

Billy felt dizzy, off balance, the full weight of Erica coming back to him. She was stronger, more determined than before. 

He shivered with the thrill and the fear, feeling himself slip toward her, feeling himself almost wanting to. 

Then it was too much. He felt the powerful sensation crash over him, felt his legs buckle as he gave in and let her take him. 

Billy watched helplessly through Erica’s eyes as she caught her breath, feeling the wonder of being so completely her. 

Fred crouched next to her, his voice a mix of awe and disbelief, “Billy?”

She was shaking, almost laughing, the sound breathy and wild, “Yes, Fred. It’s me. Billy. ”

What? Was “Erica” pretending to be him? If one thing was for certain, it was that Billy was no longer in control.

Fred reached out, almost touching her cheek, then pulling back, “Are you OK?”

She sat up, her long hair falling over her face.

“I thought... I thought she’d won,” he said, breathless.

Erica smiled, the expression almost a taunt, “Not this time.”

Billy wanted to scream, to warn Fred.

Fred said, “We can tame her.”

But Erica was barely listening. She let a loose giggle escape her lips. Billy’s giggle.

“I think I might keep this on for a while,” her voice was a sing-song tease, “See how long I can be her and still be me.”

She sauntered to the laundry room, Fred trailing behind like a loyal puppy. Erica pulled out a pair of panties and a bra, putting them on with the casual ease of someone who’d been grown-up all along.

“Are these your step-mom’s?”

Fred nodded, his eyes wide with curiosity.

Erica slipped on a tank top, her movements slow and teasing, “I wonder how long I can last before she takes over again.”

Fred watched, captivated by the apparent transformation, “You’ve got to let me try it too.”

“Let’s see how long Billy can handle being Erica first,” she said, pulling on a pair of jeans, the snug fit thrilling against her grown-up body.

Billy simmered inside her, mute and panicked.
