Designed to play on the same set of muscles from both sides, the Flex is a fun way to experiment with double penetration. The smooth dildo provides fullness in the vagina, while the soft, flexible beads stimulate anally. Best of all, the vibration from the base can be felt all the way up both sides. Easy to clean and made of Tantus's own unique blend of 100% Ultra-Premium Silicone. Flex is sure to be a versatile addition to your toy collection.
