Beverly POV

Once inside the bathroom, Beverly locks the stall door and pulls out the pussy egg from Tracy's bag. She'd slipped it in there earlier, eager to continue her naughty adventure. She looks at it with a mix of curiosity and excitement, feeling a thrill at the thought of using it in her brother's girlfriend's body. The egg is smooth and cool to the touch, with a faint scent of her own arousal still lingering on it. She brings it to her nose, inhaling deeply, savoring the scent of power and control. "Oh, Tracy," she murmurs, her voice a blend of Beverly's smugness and Tracy's sweetness. "You have no idea what I'm about to do to you."

Beverly steps up to the sink, lifts her yellow sundress to expose her bare, Tracy-like pussy, and places one leg on the sink. She takes a moment to admire herself in the mirror, her eyes glinting with mischief. She can't believe the power she holds over Tim now. She take the pussy egg, her grin widening as she brings it closer to her new opening. The scent of her own arousal fills the air, a tantalizing reminder of the control she wields. "Look at you," she says to her reflection, her voice a purr. "So pretty, so... available." She giggles, the sound a dark echo of Tracy's laughter. "Tim won't know what hit him."

She gently teases her clit, her thumb circling the sensitive nub, feeling it swell and pulse beneath her touch. Her eyes never leave the reflection in the mirror, watching as Tracy's face contorts with pleasure. The scent of her own desire wafts up from the egg, and she licks her lips, feeling more like herself than she has in ages. "This is going to be so much fun," she whispers, her voice a seductive mix of Tracy's sweetness and her own cunning. She slides two fingers into her Tracy,'s pussy, her own juices making the entry easy. She gasps, the sensation foreign yet deliciously taboo. "Oh, Timmy," she murmurs. "You're going to love what I've got planned for you."

With a wicked smile, Beverly inserts the pussy egg deeper into Tracy's pussy, the smoothness of the toy gliding in easily thanks to her own fluids. She watches in the mirror as her hand moves rhythmically, her eyes glazed with pleasure. "You're going to love this, Timmy," she says to her reflection, her voice a purr that's all Tracy. "You're going to be so confused, so helpless." She giggles, the sound a twisted echo of her sister's laugh. She wiggles the egg, feeling it fill her up, the sensation strange and exhilarating. "And the best part," she says, her voice rising in excitement, "is that you can't do a thing about it."

Satisfied with the egg in place, Beverly pulls Tracy's panties back on, making sure to tuck everything in neatly. She admires her handiwork in the mirror, her breath hitching as the egg hits just the right spot. She giggles again, the sound eerie in the quiet bathroom. "Now, let's go give Timmy a surprise," she says to her reflection, her voice a deadly whisper. She smooths her dress and fluffs her hair, the act of putting herself back together feeling like she's putting on a disguise. "Time to be the perfect girlfriend," she murmurs, her eyes gleaming with mischief. She exits the stall, washes her hands, and struts out of the bathroom, her steps full of confidence and a secret thrill.
