A Jack Rabbit surprise can only occurs under very special conditions. The Male has to have the pelvic reciprocation speed of a cheetah. He also has to be hung like a baby chipmunk. To do the Surprise a regular size condom must be worn. The Jack Rabbit happens when the condom is lost in the woman’s vaginal receptacle. This is due to the small size of the male’s member and the high PTPM’s (pelvic thrusts per minute). Once the condom is lost in the vaginal canal the male stops and yells SURPRISE!!
