Docking is something you can only do with an uncut guy, or if you are both uncut - even better!! Preferably, if you have a fairly loose foreskin. Insert the head of your cock into your partner’s foreskin and gently rub them together. Incredible! The sensation if you cum while doing it is unbelievable. Take a $1/50p trial at Cock Dockers and see it for yourself.
