My boss had to go in for some minor surgery. I went to visit her while she was at the hospital but she didn't want to say what the surgery was for. Her doctor came in at one point and told me she had to check something. She said I could sit on the chair in the room while she did what she had to. I sat on the chair and the doctor pulled the curtains around her bed. One curtain wasn't enough to go right around her bed so there were two. The doctor accidentally left a small gap between the curtains which allowed me to see a little into what was being done. I shouldn't have been looking but when the doctor pulled up her gown it got a little interesting. I was seeing her spread her legs and the doctor sticking her finger into her pussy. The gown came back down and the curtains opened shortly afterwards. I visited a little longer and at one point my boss was sitting up and tried to get a pillow that was at her feet. I stood up asking if she wanted me to get it for her and told me she could get it. She was bending forward and I could see down her gown front. I saw her pussy earlier and now I was getting a peek at what were a set of large lovely breasts. I know she didn't know I saw what I saw. When I actually said I was about to go she said goodbye and got up to use the washroom. As I was walking out of the room I looked back to see her going towards the washroom with her back to me. Each step caused her gown, which ties in the back, to open and close exposing her ass with each step. Once I had got back to my car I didn't know if I should mention what I saw to her or just keep it to myself. Anyways she is a 40 year old MILF and when I got home I jerked off thinking about what I saw.
