Frankenstein Fuckstick

A male pornstars penis which appears to be a totally different colour to the rest of his body

"God look at the Frankenstein Fuckstick on that guy, He is pale as milk and has a brown cock"

Poor Alice was about to be penetrated from the rear when she noticed a reflection in the bedroom mirror, "christ" she screamed "you are not getting that Frankenstein fuckstick near me"
