Invented by MADebito of IRC, the Double shocker is the regular shocker. Pink in anus, 2 fingers in the vagina...but...The use of the Thumb to massage the clitoris is applied.
It's like the shocker but you have to pot your pinky and your ring finger in the girls butt. The two fingers in the womans vagina are just a normal fingerbanging technique so the real shocking part is the pinky in the butthole. Therefore putting your ring finger and your pinky in the girls ass makes it the double shocker
