During the act of docking, when the man with foreskin gets an erection so that the tip of his penis pushes the uncircumcised penis out of his foreskin. Usually performed after the uncircumcised man has climaxed.
While docking Pat let out a great moan as he splurged causing his life partner Jeremy to obtain an erection thus undocking Pats now flaccid penis from Jeremy's foreskin.
