I'd been working on the office hottie at the Christmas party.

Janet was an impetuous little blond.  We were making out in the copy room, with no privacy.  Finally, she said, "The supply closet in ten.  Wait here!"  Then she took off like a shot.

Nine minutes and fifty seconds later, I opened the door.  It was pitch black.  I heard a whisper, "In the back."

Ten steps and I felt her bare ass.

"Fuck me."

I slipped inside her and pumped heartily.  She was already cumming when I heard, "See, Beatrice, I told you I'd get you laid tonight."
