So when I gave him my cum, I stopped sucking on him. At the time I did not realizing how I was just leaving him hanging, something I wouldn’t do now... But I think that he was just so happy to eat my cum, that the fact that I did not even jerk him off, was OK by him. This went on for a short while, us 69’ing, but stopping when I shot my load in to his eager mouth. Never once, in all his blow jobs, was a single drop of my cum wasted. He always swallowed it all and never let any of it get on his. I stared to thrust a bit hard and deeper to work her up to a big climax, I started to pump faster and faster. Bringing her to a climax with each strong deep pump, as she was almost ready to cum, I stopped and slowed to almost a stop. Her body quivered, she was burning hot and ready to cum. She was almost breathless and tried to say why are you stopping? I giggled and said that she wasn’t ready to cum yet. She asked why not? I said because you teased me for so long, I wanted to return the favor…. So I asked her “How ?” Her reply surprised me, but not very much. She said “ I knew it wasn’t my imagination because I was smelling them, which turned me on even more” So I knew we had actually been caught the first time when the guys came in.. So, even more intrigued, I asked her when exactly she cam to know, and she said “ When on of them licked my nipple, my face was near his shoulder, and I could smell his sexy armpit odour. Then as you were rotating them around, I could tell when it was. I took blood samples each morning and every second day I gave him a bed bath. Although I pretend to be profesional lets face it I'm only human and he is a fine looking athletic and intelligent man.I used to pay special attention washing his privates. Keeping a stance of profesional detatchment I loved handling his penis and tried to "accidentally" stimulate him and feel it swell slightly in my hands, which always made him blush terribly.On Tuesday morning I waited till the other nurses were.
