I like the abducted woman introduced/ forced into slavery variety.
A woman leading a normal life with kinky fantasies but not exploring.. Has her daily routines etc.. But unbeknownst to her, she is being watched and the unsuspecting lady in question is kidnapped & taken to the unknown. She keeps fighting, resisting but in time she accepts her place. Strict training, punishments & forced orgasms fill her life. But still there is the thought of escape etc.

The belle captive is taken to her keeper's boat and they sail to other lands. They spend a lot of quality time together alone in the open waters filled with forced orgasms, stimulation etc. When checking to a hotel in an exotic land, she is stuffed in a trunk so she is always unnoticed and is helpless.
