Exposing Myself To My Friends Wife

It started about five years ago. I do not wear any underwear and then sit in a position that allows her to see up my shorts. I do it in such a way as to pretend i do not know i am doing it but i know she knows i am getting a thrill out of it as i have sometimes had an erection whilst exposing myself. It is such a thrill knowing someone can see up your shorts and witnessing the casual glances, knowing she is looking!!
