Deeper Underground. Holly Deeper Fantasies, #1

Holly Deeper is an adventurer, a woman of mystery and intrigue. She is a bisexual secret operator, who seduces and enslaves other women. She is also the submissive consort of a man known only as Master. Holly and Master may be supernatural beings. They know the silent desires of the women they hunt. They prowl the heart of the city and out to the wealthy suburbs, making the darkest fantasies of these women come alive.  Deeper Underground Holly Deeper is riding the subway.
Master is with her, lurking nearby in the crowded subway car. Holly is following a young woman, Gabrielle. Gabrielle is wearing a tight, short, mini-dress, dressed for a night out. Holly gets right behind her. She starts to feel the young woman up. The groping gets more serious. Gabrielle is VERY turned on.  Holly yanks Gabrielle's skirt up above her waist. The train stops between stations. Then there's an announcement.
They may be stuck down here a while. Gabrielle is exactly where she wants to be - at Holly Deeper's mercy.
