Whilst it was probably the only way to see a WG who was not on the street, using small ads and contact mags we're not without difficulties. No mobile phones, no sat nav if you were not from the area. It was a lot more under the radar in those days and sometimes they would have you going from phonebox to phonebox, telling them what you could see getting nearer, until you were finally given an address. Bearing in mind you had never seen a picture so you never knew how old, what they looked like or often what service they provided. Often very little but a quick fuck with a very thick condom. Often no kissing and only uncovering the bare essentials to do the business. When you had cum, that was the end and out you go. Even if you had a fit of PE, no waiting a few mins for a second pop.
