... wait, how do the beads work

Magic and a whole lotta love.

It's explained in the other pictures. Check the source.

There's a groove or something in the dildo that draws the beads in and out of her pussy. It's pretty creative.

The dildo/vibrator has a hole near the base letting the string of beats pass through it drawing the beads on her clit, ass, and anything else. it looks like a tight fit and the panties clip onto the base of the dildo/vib so she's got to be really feeling it.

Wow. That is incredibly creative. I wonder if something like this could really work
