I’ve had this question four times in the last three days….
“How do I get my wife to read the book?”
Dude? Did you read the book?!?! A major premise is that women are curious sluts that don’t always like people knowing they are curious sluts, so they do stuff in private.
Just leave the book out in the open and then walk away from it. Say you’ll be gone a couple of hours.
Book mark the chapter you most want her to read.
You could do some sort of hidden camera routine to see if she reads it, or some sort of old school thing where you drape a single hair over the book and see if the hair is gone when you come back. But it’s probably a good enough sign if you get an unusually high sexual interest that night…
