It's a fantasy of mine that someone gets hold of my wife's secret pictures and contacts.
Since it would be a disaster for her if the pictures were sent to her contacts, she would surely do anything to prevent that from happening.

What could he do with all that?
Would he make a date with her and force her to wear certain clothes and leave her bra and panties off?
Will she have to pay the finder with her body?
Would he have hidden a camera to film everything?
Would he have copied everything?
Would she then have to go to him more often?
Would he "persuade" her to do more and more things?
Would he invite friends over to use her?
