I'm a married man and have been for nearly twelve years. Only in one of those years have I been faithful to my wife. That's because in the second year I met my "adult" lecturor at college when I took an adult course in IT. He's 54 years now, but has the body and sexual enegry of someone in their twenties. From our first meeting I had a distinct idea we'd end up having sex by the way he looked me over. I was a genuinely a straight man until he asked me after a lecture to stay back. In a small annex building I got my ever sight of another mans erection, and my first ever mouthful of warm meaty cock. Within a fortnight I was naked in the same building taking his long fat cock up my rear. At least twice a week ever since I've visited him at his apartment for sex. We've spoken about me ending my marriage, but for now at least I enjoy both sexual worlds. Being dominant at home and fucking my very prett wife, and totally the oposite at his place when he hammers away at my always eager mouth and asshole.
