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

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.

A tiny in town in Alberta, Canada. After 'Star Trek' became popular the town capitalized on the name coincidence. There's a ton of Star Trek stuff in this town - murals, a huge starship, a space station that doubles as the town visitor center.

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.

To make the Vulcan "Live long and Prosper" hand salute, then inserting 2 fingers into the vaginal opening (normally the index and middle fingers), and 2 into the anus (rather than just 1, like the shocker). "2 in the pink, 2 in the stink". This is usually performed when she is laying back, in the "deep thrust" postion.
The Vulcan neck pinch is not half as powerful as the Vulcanizer, but much cleaner
