The metro's anonymous, transient nature fuels his desire. He's insatiable, a sexual conquistador. Today, it's an older woman, her body still firm, her eyes holding a hunger that belies her years. He whispers filthy promises in her ear, making her shiver. She's eager, her hands fumbling with his belt, freeing his hard cock. She strokes him, her touch confident, experienced. He turns her around, bending her over, hiking up her skirt. The metro lurches, timing his thrusts perfectly, fucking her hard and fast, her cries of pleasure drowned out by the city's hum.
