Closely related to the shocker. Insertion of the pointer and middle fingers in the vagina and insertion of the ring and pinky fingers in the anus.
I was giving her the shocker but she wanted more, so I stuck my ring finger in her butt and gave her the vulcan.

Vulcanize that ho!

Two in the Pink, two in the stink. Then begin to do the Vulcan greeting sign from Star Trek. Use your thumb for the clit.
Here comes the Vulcan.... Oh, you like it when Spock says hello, dont you!

The Vulcan is a sexual practice in which two fingers are placed in the vagina and the other two fingers on the same hand are placed in the anus with the hand doing the Vulcan sign as a result

Like the shocker, but with all four fingers. Two in the pink, two in the stink.
Sally was bored with the shocker, so she demanded the vulcan.
