The metro's echoing tunnels resonate with the wet sounds of lust as an unknown figure, their face obscured by a hood, leads a willing participant to a secluded corner. The stranger's hand guides their companion's head, pushing it down onto their stiff cock, the metro's rhythmic sway setting the pace. The stranger's other hand grips the pole, knuckles white, as they struggle to maintain control, their hips bucking slightly. The commuter, eager to please, takes them deep, their throat muscles contracting around the stranger's length, leaving them both breathless as the metro screeches to a halt at their stop.
