Electric Handshake

Similar to The Shocker; the Electric Handshake describes the act of simultaneously stimulating the vagina and anus.
However, all fingers are used, in a three-to-one configuration.

It is symbolized by an outstretched hand, as though offering a handshake, with the pinky slightly dropped.
