The late-night subway car is dim, offering anonymity to the two strangers who find themselves face to face. One, a confident woman in a business suit, notices the other's nervousness, her hands trembling slightly. She leans in, whispering, "First time?" The younger woman nods, blushing. The older woman smiles, her hand sliding onto the younger's thigh, feeling the dampness through her skirt. She guides the trembling hand to her own crotch, showing her how to touch, how to ignite pleasure in the most public of places.
