There are no limits to your imagination and joy of experimentation with the Cluster Buster & Sultry Sub. Whether bathing for hours in gentle tingling or letting yourself be driven to ecstasy with brisk pulses in the right place - it spoils you from tender to intensive to hard. Are you open to new things? You have the choice between twelve stimulation and five training programs. For example, you can also make the pelvic floor fitter, which is particularly required during lovemaking. One Year Warranty.
