I think we know where this is going...

"Anything of yours, hmm?" Bonnie asked, her smirk growing wider as she placed her hands behind her back and slowly walked around you.

"Yeah, pretty much." You reply. "My laptop, my bag, my chair..."

"Your towel?"

"My tow-" Your eyes widened in horror as you finally realized the one drawback to your bargain, slowly turning to see Bonnie's smirk having turned into a hungry grin. "Wait! Hold on! Not -"

But alas, it was too late. Bonnie reached out and whisked the towel right off your naked body, exposing your plump ass and six inch package.

"Twit-twoo!" Bonnie whistled loudly before letting out a laugh. "Bet you won't forget about the game now. By the way, nice ass, John!"

Bonnie punctuated that statement with a sharp spank to your naked ass, causing you to yelp as you turned around to face her. Unfortunately, this allows Bonnie to have a full view of your partially erect manhood before you throw your hands over it in a move that's too late, your face burning in embarrassment.

"Bonnie! Please! Give that back!" You beg in a hushed voice, not wanting to draw any more attention to your situation.

"Hey, you're the one who said I can take something of yours as collateral." Bonnie said, waving your towel like a flag. "And I took my collateral."

"That's not what I meant!" You snapped, "Now give it back!"

"Hmm... Nah." Bonnie said with a laugh as she turned and raced down the hall.

"Bonnie! No!" You shout as you streaked after your coworker, cupping your balls and manhood as you burned redder and redder by the second.
