For this one, I would be either a traveller that a biker pack finds by my stalled car. The leader sees me, and decides to keep me as their companion, dressed in black leather, or perhaps as their schoolgirl fantasy, kept with them wherever they go, pleasuring him or her, unable to escape.
The second idea has me as a DA, a good one. After successfully prosecuting a gang leader, the new leader has me kidnapped and made into his companion, suitably dressed and kept with them, unable to escape.
If either of these ideas appeal to you, let me know.
