The city bus rumbles to life, carrying with it a hidden secret. A discreet hole in the wall reveals a hungry, waiting mouth. A gay man, aroused by the taboo, steps onto the bus, his eyes scanning the crowd, looking for his next anonymous encounter. He moves towards the back, dropping to his knees, and with a practiced ease, takes the offered cock deep into his throat. The stranger groans, his hips bucking slightly as the skilled mouth works him over. The bus lurches, and the gay man's head bobs, bringing the stranger closer and closer to release, until finally, he spills his load, the gay man swallowing every last drop before the bus pulls to a stop, and the stranger disappears into the night.
