Geisha balls

We are witnessing a real craze for the geisha balls after the release of the erotic novel " 50 shades of Grey ". The geisha balls are a sex toy and an accessory for rehabilitation and strength training of the perineum. They are also known as the balls Ben Wa (阴道球, yīndàoqiú, "balls vaginal" or 内用球, nèiyòngqiú, " balls for internal use ").
