Cum Obsession

I have a strange obsession or fetish regarding my husband's warm cum. Whenever I am in town in my office, I love to have him take me to lunch, and after we return to my private office, if my day allows a little time after lunch, I ride him and love hearing work going on just outside my office door while hubby is getting excited to the point of no return. I tease him getting him really desperate to release his cum in forceful throbs filling me with warm sperm. My secretary has been with me for years and she knows and will block off time right after lunch for me to do this. What really turns me on is to have him fill me up just before a meeting, so that I can put my thong on right away so during the meeting, I can feel his warm cum slowly spreading inside me and then leaking out of me while I am in the meeting. I have found that some positions more than others, seem to take longer for him to dribble out of me and that turns me on the most. My secretary will sometimes come in as soon as he leaves and smile at me since I know she can smell our sex. It doesn't interfere with my work and nobody but me or my secretary knows, so I love and will continue to do this.
