What industry does your WH work in ? How can he get that much privacy to not get caught jacking off while on the clock?
He was a mobile home salesman for a small family owned business. He was one of three salesman. From 9-5 his boss (the owner), the financing lady, and another office lady would work. They would all leave early some days, however. He wouldn't leave until 6 most nights. On Saturdays it would be only him and one other salesman (I'm not sure if him and OW ever worked a Sat together). OW worked on another lot completely alone in a town about 45 mins away. WH trained her but according to him they were NEVER alone together because she always left when everyone else did. He said he would masturbate after everyone left so I guess between 5 and 6? Yet, his search history showed most days he was looking a porn (on facebook) at 2 in the afternoon.
He has since left that job, by my request, and drives a truck for WM.
