I Fuck My Sister At The Office

I get a call from my friend with very exciting plans and I can’t say no. But there’s a problem, I still have 5 more hours to cover in the office, what should I do?
To my right I see my coworker, I would never think of doing anything with him but leaving early on a Friday sounds awesome, so I convince him to let me suck and fuck him for him to cover up for me. Needless to say, he agrees.
