A couple of times a week I find myself naked, hard and jerking off at work! It goes like this: I get in 2-3 hours before any of the other employees, except the janitor -- a married guy in his twenties. He's always there before me. We talk, I go to my office, he goes about his business. The thing is, he never takes the stairs (always the elevator) and has a set routine.

There's one main stairwell in our 3 story building. The pre-hours entrance is on the bottom floor. I've discovered that I can strip down to nothing and hang out on the upper floors while the janitor does his thing on the lower floors. Once he makes his way to the 3rd floor (via the elevator) I just run -- with my hard dick flopping -- to the next level down in the staircase. The challenge is to spy on him while I'm completely nude without him seeing me. If anyone comes in via the pre-hours entrance (which is rare) I can always hear them before they enter and pull on my clothes -- usually just in time. It's a real turn on!
