LELO MONA WAVE simulates fingers motion while they are into the vagina so for the Orgasm to End All Orgasms

We are going to borrow the following text, of one of the leading sex toy reviewers in the world- XTRA CARRUCURAR -
"The new INA Wave™ and MONA Wave™ were designed to address a serious subject: the relationship women have with their bodies. The motion of the products closely recreates the sensations of a partner, sensations that are hard to produce in your own body alone. The LELO Waves give that power back to the user – they allow her to take complete control of the pleasure that would otherwise only be offered by a partner. In short: INA Wave™ and MONA Wave™ give you complete ownership of your orgasm.

With its voluptuous form and beckoning ‘come-hither’ finger-like motion, MONA Wave not only takes you to the limits of pleasure, but pushes you over the edge to a whole new world.
