I remember when i was about 20, a 'mature woman' at work, probably early 40's, fit, trim and a natural blond, took me out drinking. she held her liquor way better than I, but we fucked in my car, in her bedroom, in her living room, until she announced that her husband would be home soon and that I had better...i was gone before she finished the sentence. at one point i do remember was asking her in a drunken slur "how old are you anyway?" I was young AND dumb! One of my most memerable and best lays, to date.
My advice...don't ever pass on an older woman
