When fisting a girl fully submerge fist up to your wrist into the vagina.Extend fingers and proceed to turn the imaginary doorknob. The proper application of this technique will make a "boot stuck in the mud sound".
I introduced K love to the doorknob technique I think she's my soul mate.
A technique in which a male or female assertively grabs hold of a sexual partners penis, preferably the head, and massages it vigorously in the motion of a turning doorknob causing both mild discomfort or pain with intense pleasure. -
Said to be created by a good friend C. Powers
