I sucked off a driver who was taking me to the local gay bathhouse. He gave me his personal mobile number to call him when I need a cab. Now I have a couple with that arrangement. One is a horny chub the other Indian.
I've sucked off taxi drivers who are bored and horny while waiting for fares. There is a parking lot near a gay cruising park where they know cock suckers like me will often approach them and suck them off. I always swallow so there is no mess in the cab.
