Game of truth and dare?

"I have four pieces of clothing on me, and you both have hidden your bodies with two hands each", Julian said, "so for each hand you remove, I will remove one layer"

Julia raised an eyebrow, her confidence flickering as she processed Julian's words. "So, if we remove our hands, you'll strip? That sounds like a fair trade."

Isabel glanced at Julia, her cheeks still flushed. "Are you sure about this? It feels a bit... daring."

Julian nodded, his expression playful yet serious. "Trust me, it'll be fun. Plus, you both might enjoy this more than you think." 

Julia smirked, her competitive spirit ignited. "Fine, I'm in. Let's see how you handle it, Julian."

Isabel took a deep breath, her eyes darting between Julian and Julia. "Alright, but we better not regret this."

With that, Julia slowly lowered her hands, revealing her breasts while still keeping some modesty. "Okay, one down."
