I asked her to close her eyes and hold out her hand. She gave me a look, but did as I requested. I opened the small box I had hidden in my pocket and tipped the contents into her palm. I liked the delicate sound the metal balls made as they rolled around in her hand, sensual and alluring. How could something so small offer so much promise?

Rolling pleasurably into the spotlight thanks in part to a very memorable appearance in the Fifty Shades legacy, these perfectly weighty, ultra sleek, 100% stainless steel classics offer a deliciously self-indulgent way to prime for pleasure, strengthen sex muscles and increase sexual awareness.

Long before they catapulted into the public eye thanks to a titillating appearance in the ultra erotic Shades trilogy, ben wa balls have held a place in history, both sexually and in health-related scenarios. In Japan, elite courtesans were thought to wear the balls constantly as a way to strengthen the pelvic floor muscles, giving the courtesan's 'pleasure quarters' a very literal meaning. Today, this type of sexual tool is still used in a variety of ways, but most often, the balls are used as kegel weights for vaginal strengthening and to increase sexual awareness. The weighted balls help you exercise the muscles in the pelvic floor responsible for sexual pleasure, while keeping the vaginal walls elastic and responsive to stimulation and pleasure.

This pretty silver 100% stainless steel set is ideally designed for customized use and enjoyment. If you're a true beginner, you may want to start out with a single bead, the set combined is 56.6 grams, with each bead weighing in at 1 oz (28.3) grams. Once you have the Balls inside you, in whichever combination of weight you desire, they'll naturally pinpoint the muscles needed to create a stronger pelvic floor, as you'll need to contract these muscles to keep the bead(s) in place. For those who already practice kegels and vaginal strengthening, the weighty spheres can help further tone and highlight some of the more subtle contraction combinations and muscle reactions.

Aside from the practical applications of this fantastic system, the Balls are also a way to gain increased sexual awareness, as our friend Anastasia Steele discovers in the Fifty Shades scenario. Moving around while wearing the beads creates a pleasant, subtle feeling of pleasure, as the Balls gently vibrate and jiggle, naturally stimulating the vaginal area. Many women love the full sensation during wear, and find that it increases desire, making the Balls a great way to get ready for sex. Since this set is so incredibly discreet, you'll be able to wear it unbeknownst to anyone, letting you get your workout (or simple pleasure) secretly and enjoyably. The temperature sensitive, naturally warming Balls are completely hypoallergenic, compatible with any type of lubricant, and are extremely hygienic.
