After Hours
When I lived in South Africa, I was manager of a branch of a large industrial tools company. The branch was located on a moderately busy street and the front 'wall' was one plate glass window, fitted with reflective film to keep the office cool. That meant it was just a giant mirror from the outside. Most people couldn't resist looking at themselves as they walked past, and some would stop and tidy their hair or whatever. I liked it when young girls stopped as I could study them closely, checking out their tits. The South African climate meant there was no need for heavy coats, so there was a nice selection of skimpy, semi-transparent or low-cut tops on display.
I couldn't do much about it during working hours ... but after hours was different! Once the staff had gone home, I would lock up, strip naked and start putting up the orders for next day's deliveries. As I worked, I kept an eye out for girls using the 'mirror' and would go back through to the office and stand right in front of them and masturbate. It was very stimulating, standing only two feet away from them, especially if I could see their nipples. It was as if they were looking right into my eyes. I knew I couldn't be seen, as I had checked! It had to be dark outside and the lights had to be on inside before you could see through, even if you cupped your hands on the glass and looked in.
One evening the phone rang. When I answered, it was the Marketing Director from head office. He was just phoning on the off-chance someone might be there, and he was surprised when I answered. I explained that I stayed back to put the orders up and gave him the information he had phoned about. At the end of the month, I was pleasantly surprised to receive a bonus in my salary. Win-win!
It would make it even more exciting for me, knowing your wife was aware of what I was doing. I would love to have it filmed from my side of the mirror, then I could see her and myself at the same time!
My wife loves mirrored walls and puts on a nice show in front of them hoping someone is watching she would really get into it if she knew you were naked on the other side watching and masturbating
