Supprised By Mother In Law

The First time I can remember being caught nude, not on purpose, was when I was first married. My wife worked the morning shift 8am to 5pm and I worked the 3rd shift 11pm to 7am. This way we didnt need a babysitter for our new son. I would get home just before she would leave for work and then I would take care of him. This morning had already been hectic with me being a bit late coming home, and the wife having to hurry out the door. The Baby was still sleeping so I decided to take a quick shower and try and get some rest while he slept. The appartment was small and had only one bathroom in a hall way between the two bedrooms. I had gone into the bedroom and taken off my clothes, was adjusting the water when I heard the baby cry. I went to his room and changed him and then had picked him up to go get his bottle, when I felt someone looking at me. As I turned around with the baby in my arms I saw her standing there not saying a word. I just pushed out the door and went to get the bottle for the baby like I was dressed, she followed me to the kitchen, then back to the bedroom, I laid the baby on my bed and got a robe, then I ask her how she got in the house, and she told me she had a key, and my wife had told her to come by any time she wanted to. I took the key and showed her the door, and the door bell. I put the baby back in his crib and went to get my shower, when I came out there she was again this time holding the baby. You see I forgot about the hidden key outside. I still wonder how many times she had done this before that i didnt know about.
