Be warned the sneaky serpent is not for the weak minded. It involves ass to ass sexual relations. To perform the maneuver a male and a female must begin ass to ass. The maneuver first begins with the man tucking his erection between his legs. The balls must be split for this to occur. For the penis to reach its final destination it must be an adequate length, at least 8 inches. From there the female is going to have to do the final job of penetration because the man will be unable to move in such discomfort. The difficulty of the position makes it ideal for any man and women wanting to play "just the tip"
