He ever-so-calmly wiped the corners of his mouth, like he had just finished a full-course meal at the officers’ club, and then opened wide to show t...at he had swallowed Gap’s load completely. Everyone was in awe. He slowly staggered to his feet, and there they stood ... face-to-face. If I remember right, Bob was wobbling pretty bad at that point, but you could have heard a pin drop. Then came the piece de resistance: Just as Bob was about to plant another big kiss on Gap’s mouth ... it. “We’ve been sent to, well, check you out and see how you wanted to do it, you know, service us.” “Fuck you?” I said with a smile.

There is a knock on the door and someone walks in. You sit at your desk and I am under eating your pussy while a clerk hands you some papers and starts to explain what they are about.I suck hard on clit and wiggle fingers in pussy pushing deeper causing you body to tense and I feel a slight quiver in your belly and hip.I can hear the conversation and you are getting upset they have not left and finally you tell her that you know all about it and she can go.She leaves and as the door closes you.
