Couples toys are devices that are designed to be used in the company others: girl-boy or girl-girl or any gender variant that seems appropriate at the time. After all, sharing is caring! Or is that vice versa?
In some BDSM kits, the feather ticklers that are included aren't fit for purpose; they supply a bit of relaxing fun for someone who's on the receiving end but that's all. If you want to tickle someone properly then a different kind of equipment is worth considering. Real enthusiasts of tickling do without mundane feathers or little pieces of coloured fluff. They know precisely which tickle fetish toys will yield the desired results. In fact, Mother Nature has amply provided us with a wonderful variety of organic options.
