In the bustling, dimly lit metro station, a stranger catches your eye. You're both there for the same reason, the thrill of the unknown, the danger of being caught. She's dressed in a trench coat, hair disheveled, eyes hungry. You follow her into the secluded corner of the platform, hearts pounding in sync with the approaching train. She unbuttons her coat, revealing nothing underneath. You're hard instantly, your hand finding its way into your pants as you stroke your aching cock. She watches, licking her lips, before dropping to her knees, taking you deep into her warm, wet mouth. The train arrives, lights flickering, but you can't stop now. You fuck her face, her tits, until you both climax, panting, before disappearing into the crowd.
