A Christmas Cumslut
Unbeknownst to you your secretary has a family meal panned for the evening and is in a rush to leave work. So she slips out of her bra, climbs onto your desk and strikes a provocative pose to help the cum flow out of your cock.
Unfortunately for her, you give the orders around here and not her, You stop stroking immediately, walk over to your secretary and smear you pre-cum on her lips before sternly stating "now listen here you dirty slut, I am in charge here and if I wanted to see your tits I would have asked for them, not get out of my sight."
She thinks she has had a lucky break, after all she may now leave work and join her family but a good fucking in front of the other staff on boxing day will be what awaits her on her return. Your cock begins to grow again at the thought of fucking her in public and the humiliation it will cause her but you resist the urge to start stroking again and head home.
