Hmmm, interesting question and one i've not really considered before but since you ask...
First it would be a woman i've kidnapped off the street (black van style, skidding tires, side door flying open and just whisking her off in broad daylight).
Then it would be a safe house somewhere that I can keep her for as long as I want. The first few days would be some sleep deprevation torture and at least a half a dozen video monitors contantly piping in different flavors of porn so i could watch her remotely and see what kinds of things she zero'd in on when she thought no one was looking. Even though she would be afraid, repelled, and disoriented eventually she would respond. every few hours i'd come in the room, sneak up behind her and blindfold her so she didn't know who or what to expect then come around to the side of the bed she was strapped in and roughly massage her tits, slap and finger her hole, all while she cried and begged for me to stop.
after a day or two the sensory overload would have her reaching orgasm against her will, her body betraying her. After that if she did not cum immediately after my rubbing of her pussy and fingering of her asshole she would receive increasingly harsh slaps to her breasts or choking just before the point of passing out maybe even flipping and re-tying her on her belly so I could whip her from her shoulders to her calves for not cumming on command.
maybe a day or two later complete isolation, just darkness, no binds, just microphones so I can listen to her breathing for a day maybe three. Then the porn assault resumes but she is not bound, just locked in the room and an assortment of vibrators, dildo's, some shaped like dog cocks for her to choose from.
The next day back to being tied down so she cannot masturbate if she wanted to, no telling that she would? just that she can't. More porn coming at her from all sides and a continuous soundtrack of women moaning, sighing, cumming and breathing matched to a subtle club like bass line beat. after a day or so of this treatment I will again return to her quarters and blindfold her as always then eat her pussy until she cums, pinch her nipples and eat her pussy and ass until she cums, when she's worn out, leave her again.
after a few weeks of watching the news about her abduction and gauging how her programming is going I finally fuck her and clean her up then return her to the precise spot i've abducted her from, dressed exactly as she was when I took her.
After that I just monitor the spot I originally took her from and if she returns I abduct her again and re-double my efforts.
