The girl pants heavily as she comes down from her high. Her body still trembles with pleasure, but it seems to have given her a newfound confidence. She looks up at Sarah, a sultry grin spreading across her lips. "Cum inside me," she whispers huskily.

Her words send shivers down Sarah's spine, making her cock twitch eagerly within the girl's tight grip. It feels so good to be wanted like this...

The train whizzes past them as they fuck on the floor of the empty car. Sarah can feel herself getting closer and closer, her breath coming in ragged gasps as she thrusts harder into the girl. Her cock throbs against the girl's inner walls, threatening to explode at any moment. The girl looks up at her with a mixture of lust and desperation, urging her onward.

With one last powerful thrust, Sarah feels her climax building deep within her core.
