It's your 25th birthday and right now, only Vance, your best friend, and her boyfriend remained. After you disappeared into the bathroom to try whatever your best friend prepared for you, Vance stayed in the kitchen and exchanged a few words with your bestfriend and her boyfriend before they left.

Vance smirked, glancing down at his phone, trying to make sense of the app he’d just downloaded. He hadn’t thought much of your best friend’s hurried instructions, figuring it was some quirky prank or party game. But when he dragged his finger across the screen, watching the small circles and swirls he was creating, the last thing he expected was for you to gasp like that.

His gaze shot up to see you in the doorway, fingers gripping the edge of the counter, eyes wide, cheeks flushed. Your back arched involuntarily, and the realization hit him all at once—exactly what he was controlling with every swipe.

A wireless controller?

“I didn’t realize technology could do that.”

From that moment, Vance realized what this whole "surprise gift" was all about.

A vibrating lace thong.
