On a late-night, near-empty metro, two teenage girls, Heathers, find themselves alone in a car. The city lights flicker outside as they start to chat, their voices echoing in the empty space. One girl, intrigued by the other's confidence, leans in for a kiss. Their hands explore each other's bodies, feeling the curves beneath their clothes. The train rumbles on, but they're lost in their own world, their passion growing, their moans filling the car as they bring each other to climax.
