Do I dare?

I have a fantasy that involves a co-worker that has basically groped me for the last 5 years. I think it started out innocently enough but now I frequently think about the things I would do to him. We are standing in a room at work behind closed doors and I slowly pull down his pants (to his futile plea "not here", "NOT HERE") to expose his cock that is giving away his true feelings about what I will do next. I can imagine grabbing the shaft of his cock (average in size, I don't want to be to ambitious right out of the gate) and wrapping my lips around the head. I can hear his breathing speed up and low moaning start at the same time his hips are starting to gyrate with my sucking. His cock tastes good in my mouth and I enjoy the softness of his member. My hand starts to stroke his cock in between sucks and now his eyes are closed and he keeps whispering "don't stop now", "keep sucking". His cock starts to get harder and I can feel him swell in my mouth as he gasps and shoots a giant load of cum over my lips and face. I can't believe how warm it is on my skin and I really enjoy this part. Saying nothing, I get to my feet and wipe of as much jizz as possible, leaving him with a blank expression on his face. Next up...diner date with a seductive lady in her favorite pair of black thigh highs.
