When two men unite by joining their penises, head to head, to make a rod with one back. The foreskin of the dominant male (or space station) is wrapped over the end of the smaller knob belonging to the submissive male(or moon unit) to great a blind, but elongated penis shaft.
Son: Hey Dad, while I'm not really into penis docking it might help us to do some father and son bonding. Dad: That would would be lovely son. I haven't felt the touch of your knob for years.
