Left to do overtime

"Mgpphhh!" Rachel tried to defend herself, saying that the piss was fresh and she had been cleaning all day, yet all that came out were muffled protests as her gag prevented her from talking.

"That's it! Until you clean this toilet up, you're not going back home for the night! Consider this... Overtime." Celeste crossed her arms, angry at Rachel's incompetence.

"Report to me when you're done and I'll come check your work. I'll be in my office down the hall doing paperwork, don't try to get away, I'll check the security cameras stationed outside the toilets from time to time." The raven-haired woman instructed as she huffed, pushing her neat bob cut to the sides and turning away before Rachel could utter any further protest.

"Mghhhhh... " Rachel grumbled through the gag. The only time she had to look forward to was when her shift was over and she was allowed to go home, finally being able to dress in clothes again and stand upright instead of on all fours.

But now, she had received what every employee feared: overtime.

Stupid Celeste! Always giving me a hard time! I'll show that stuck-up bitch one of these days... Rachel thought to herself as she went to grab her cleaning cloth, imagining all the ways she would get back at Celeste. One of these days, Celeste would be the one laughed at and groped by gross **** men, nude and crawling. See how she likes it.

But for now, Rachel was the one suffering. She grabbed her cloth and wet it, setting to work.

Rachel placed the wet cloth in the floor, intending to take her time since she knew most customers had gone to bed or were using their room toilets at this hour. She spread her thick legs and exposed her tight pussy and asshole towards the door as she leaned toward the yellow stains, rubbing them away.

Her huge ass wobbled and shook in the air as she really got into it, rubbing hard to make the floors as spotless as she could.

She was so invested in her work, and deep in **** fantasies, that she didn't notice the door slowly creak open again...
