You made some little mistakes

You continued your work. From time to time your arms brushed your bosom and caused the bags to jiggle a little. The unknown sensation of two heavy bags jiggling on your chest distracted you, causing you to make some little and unnecessary mistakes.

"I thought you wouldn't make such silly mistakes." Stephanie said astonished.

"I'm sorry, but these things are distracting me." You point towards your chest.

"Well, either get used to them, or ..." She took her handbag and dug through it, until she took out something in the same color as the bra you are wearing. With one finger she held the lacy cloth towards you.

"You can't mean it." You back off a little with your office chair.

"A deal is a deal." She reminded you with a big smile.

You let out a sigh and grabbed the cloth. "Is it ok if I use the toilet?"

"Sure." The redhead answered. "Thought I wouldn't have a problem with you doing it here."

"Definitely not." You replied heavily blushing.

You went to the toilet and locked the door behind you. You looked at the cloth in your hand and let out another sigh. "What place did I step into?" You unfolded the cloth and looked at the lacy thong. It must have been a spare one of Stephanie, as it matched her bra. You asked yourself if you should really put it on, as agreed, of if you should try to fool Stephanie.
