Handjob with a pearl necklace???

Ok so I was doing some research to spice up our sex life, and I found this one article that told you how to give your man a handjob with a pearl necklace. Basically, you wrap it around his penis so it's completely covered and then do your normal handjob stuff. Oh and use lube.

What do you guys think of this? It sounds like one of those extreme fantasies, and honestly I could see so many ways this could be painful. 😂

Here's the link to the website if you want to read it:
