We have 20 minutes

Boss left, time to get dicked by the intern. Ever since the new guy started working at the firm, the bastard knew he was going to be a game, but there was never any opportunity left. There were always too many people in the office to prevent even a quick hook-up. But the big day arrived. The boss called the group to see something in the building but they didn't go and had 20 minutes to enjoy it.
