It was difficult to tell. From the body you would have thought late 20s, but she was obviously much older than that. She clearly kept herself youthful...and that alone made me instantly attracted to her. I'd later discover that she was 48, 18 years my senior but my god I was smitten!As I settled into my new job I became more and more impressed with how gorgeous this lady was.

You have all of the equipment. She had me wanting more of her and I couldn’t wait to get there. I pulled into a parking spot just outside her apartment door and I checked myself out in the rear view mirror. Call me vain, but I really did want to look good for her. Just something about her wanted me to look more presentable than I usually had done. I got out and walked up to her door. I knocked and waited for her to answer. She opened the door and said “Well hello there, stud.” I could feel the redness flow across my face..
