As the subway car rattles through the city's underbelly, two black beauties, one with curves that defy gravity, the other lean and athletic, find themselves in a cramped corner. The air thick with the scent of sweat and desire, they inch closer, their legs brushing, eyes locked. The taller girl, her skin glistening, reaches out, tracing the other's full lips with her thumb. The shorter girl responds, her tongue flicking out to taste the offered digit. The train lurches again, pushing them together, their bodies grinding. The taller girl's hand finds its way under the other's skirt, fingers probing, finding wet heat. The shorter girl gasps, her own hand snaking up the taller girl's thigh, their bodies moving in rhythm with the train's motion. The world outside is forgotten, replaced by the primal dance of these two black coeds, lost in their urban lust.
