The train's rhythm sets the tempo for Rossa's throbbing desire. The station's cacophony fades, replaced by the symphony of Troia's moans as she grinds against him, her breath hot on his neck. Piroshka, watching from the corner, bites her lip, her panties dampening. As the train rolls into the next station, she seizes her chance, pushing Troia aside and taking Rossa's cock into her mouth, her tongue swirling, eager to taste his precum. Troia, undeterred, watches, her hand sliding into her panties, fingers dancing on her clit, ready for her turn.
