This is mine. Highly unlikely and highly dangerous if it were to happen:
I would be either kidnapped or bought from a slave market. From there it would be me resisting my typically male or futa captor(s)/owner(s) as they break me down physically and mentally down to nothing as a way of "training" me to be their personal cumdump or breeding bitch. I could and would be used by multiple parties and not necessarily humans. This could even go into darker fantasies too, possibly involving blood play, knife play, and branding...
