Any number of balls, usually of metal and a little smaller than a ping-pong ball, inserted either in the vagina or, especially in gay erotica, in the rectum, and then pulled out slowly, producing for many people an intense sensation of pleasure.
The pull-string broke of the ben wah balls, so he wasn't able to extricate them from his ass.

Ben Wah Balls (or Duotone Balls)refers to a sex toy primarily used to pleasure the vagina before sex. These balls on a string are hollow and can be used for man-woman and woman-woman sex. The purpose of Ben Wah Balls is to enhance sexual intercourse. In a nutshell, you insert them into the vagina using your pubcoccygeus muscles to hold them in. Do not use them for anal sex, as they do not have an adequate flared base for safe anal play. Some of them have chimes or clappers. They come in virtually any color. These Balls are marble sized. You can also use Ben Wah Balls to strengthen the vaginal muscles. These Balls come on either a chain, or silk string for easy removal. You can even leave them inside your vagina for a whole day and rock back and forth. This is a great way to strengthen your pelvic floor muscles! These sex toys have been used ever since Taoist sexual practices originated. In addition, you can use them for incontinece and bladder control.
Mary and Johnny like using Ben Wah Balls for superb vaginal foreplay.
