I have used these Anal Gel Beads in a few videos, they make for a very intense orgasm.  I have used them myself and I very much recommend them, if you like a little or a lot of stimulation!!!.  Rubber beads formed on a rubber string makes using these jelly style anal beads easy for novices and experienced bead users. Insert as much as you like, then quickly remove at the point of orgasm.

The packaging and product may vary slightly from the photos, these can be difficult to get so I get them from the supplier has them in stock, at the time.
