What is Vulcanizer?
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
