Late Night Fantasies in the Break Room

I work nights at a busy warehouse and have plenty of downtime between shipments. One night, after hours alone in my office doing paperwork, I couldn't resist sneaking into the break room for some solo time. With every flick of the wrist, sliding that slick toy in and out, I imagine it's someone else, my best friend from high school, or even my boss, and let myself go wild. By the end, covered in sweat and coming hard against the back of a chair, I wonder if anyone has ever done something similar during their late-night shift? Is this just normal human curiosity, or am I way off track here?
