Yeah, in the train.

She is standing near the exit of the train.

2 guys are standing there, too, watching her.

The roundness of her hips is well defined by the thin fabric of her short skirt.

Another observant man is sitting not far. He is the first to notice it.

He gazes not at her inviting ass but at her legs.

This man is surprised as he finds the silvery dripping between her legs.

Soon, all 3 men watch cum dripping downs her knees and ankles.
