The latest trend in #Swinger fashion is the Butt Plug Extreme Bikini. It solves the problem of strings up your back by anchoring the front string in a butt plug up your ass. It is impossible to wear this without the butt plug. The single string runs between a neck collar baring the tits & nipples down to between the pussy lips to the anchor butt plug.
Swingers love this sexy new thong bikini which looks totally bare ass & bare back. You can buy this at www.a-s-s.ch
