The city's rhythm echoes in their hearts as they stand, entwined, in the packed metro car. His hands roam, finding her secrets, as she grips his throbbing cock through his jeans. The train stops, people push, but they stay locked, their bodies moving in a lewd, silent rhythm. Her breath hitches as he finds her clit, rubbing it in time with the train's rocking. The city outside blurs as they chase their release, anonymous lovers in the urban jungle.
