Double Jacksaw 

The act of counter-rotational fellatio in which the giver harmoniously utilizes both hands and the mouth for maximum stimulation during blowjob. Traditionally, the left hand is on bottom and right hand on top while one rotates and the other counter rotates on the shaft while the head of the penis remains in the performer's mouth. For full effect, the two handed rotation and counter-rotation must be coupled with up and down motion on the penis and blowjob until explosive orgasm in the mouth is achieved.

**WARNING: NOT FOR THE INEXPERIENCED**
