We've been doing this for a bit over FIVE years and I don't think we'll stop any time soon. As an aside, my wife is also in the health care profession (R.N.) but only one man that she works with has ever gotten her. He's a lab tech, so they do have a lot of professional contact at work. When he first started fucking her they would have quickie contacts in his area, which was usually just a blow job. (They work evenings) But one night they were almost caught by the cleaning crew, so now when they meet it's just a nod and hello. After work is different. He's also married and has to be home within a reasonable time after he gets off, so their time is limited. BUT he has a van, so my sweet little wife can get Black Cock injections on a parking lot!
