Two strangers, both women, find themselves alone in a dimly lit subway car, late at night. Their eyes meet, and an unspoken understanding passes between them. One, dressed in a sharp business suit, reaches out, her hand gently caressing the thigh of the other, clad in casual jeans and a t-shirt. Their hearts race as they explore each other's bodies, hands roaming under clothing, finding warm, eager flesh. The train rumbles on, a secret accomplice to their forbidden tryst.
