What they're not telling you is that these are anal beads the wife will have to cram up their ass. So the incentive is for them to have less beads. Or more. I'm not sure.
If I tried this shit with my wife, she'd have a U-Haul back to Michigan rented in less than 24 hours. It's like bringing a case of pineapple juice to the office as a hint to the Human Resources Assistant that you want a blowjob at lunch. Which also doesn't work, I have heard.
