The metro's hum and rumble provide a steady rhythm as the Heathers, oblivious to the world outside their car, succumb to their forbidden desires. They lean in for a first, tentative kiss, tongues tentatively exploring. The scene quickly escalates, with one Heather pushing the other against the hard metal wall, hiking up her skirt, and burying her face in her warmth. The other moans, her fingers tangling in her friend's hair, urging her on. They're a mess of tangled limbs and desperate, whispered pleas when the metro lurches to a stop, their interlude cruelly cut short.
