The Super Soft Duo Balls feel silky and smooth and they roll silently around in your love chamber! The soft casing helps them to slip and slide around your G-spot and turn you on in ways you never thought possible! The balls are made from flesh coloured plastic which is easily wiped clean after use and are highly durable. The balls do not need batteries and work off their own momentum much like ying yang balls. This means that they are completely silent so your flatmate won't think you're drilling a hole in your bedroom wall every time you slink off for some solo sex play! Furthermore, they won't lose power at that crucial moment. The balls are attached by a fine piece of cord and have a handy retrieval string which prevents them getting lost inside you. So let these bad balls loose in your pussy and it'll be purring all night long!!
