You got confronted

"Seems like somebody loves dressing up like a woman." Stephanie said as soon as you left the toilet.

You were thunderstruck that she confronted you with it. "How... where... I mean..."

She stood up and walked over to you. "Don't worry, I won't tell anybody. Though Nicole must know it too." She leaned in and whispered in your ear. "Fortunately the walls to the other offices are thicker than the ones in the office."

You heavily blushed and wanted to curl up and die. You never even thought about somebody hearing you masturbating.

"I can keep your secret, if you want." Stephanie said with a cunning smile. "But it wouldn't be for nothing."
