The Two Hand Ham Twister (THHT) is an advanced form of head in which the one giving head has one hand on the base of the dick and one hand near the top and twists them in opposite directions back and forth while simultaneously moving both hands up and down in sync with each other and the mouth giving the head. This type of head requires a considerable amount of lubrication and skill and it is also the type of head Simon is receiving.
