This is a form of dogging that happens in markets or bazaars and is usually accompanied by shouts from the crowd of "bak sheesh, bak sheesh". The couple copulating usually have to have intercourse in a small contained place reserved for urinating and faecal waste hence they form a pyramid shape to avoid the shit on the floor.
Even though Susan was from Rightford she still dogs egyptian like a seasoned pro. Her proffered ass and pyramid stance meant I could give her good and made for a fantastic egyptian dogging scenario. The cries of "bak sheesh" made me ejaculate into the pocket of her carrybag.
