Sex balls
From Voyeurweb's Wiki about Sex
Sex balls are a sex toy. Other names for sex balls are "Ben Wa Balls" or simply "pussy balls" or "ass balls". Sex balls are usually two or more small balls made out of metal or plastic linked together by a string or chain. The balls are hallow and contain a small weight which rolls around with every movement of the user. Sex balls are inserted into the pussy or anus and supposed to sexually stimulate the woman wearing the sex balls. However most woman report that the usage of sex balls does generate little to no sensations.
Sex balls vary in dimensions, weight and number of balls. Smaller balls are used for anal insertion and are called anal beads. Huger balls are used for vaginal insertion.
