Cock knocking involves two males. One male has "trained" or "stretched" his penis hole, commonly using house hold objects such as markers and progressing to larger items, etc.
The second male inserts his erect penis into the urethra of the male with the "stretched" hole and they proceed to have penis to penis sexual relations. often resulting in disturbing infections.

Get the cock knockingmug. A cock knock is when two men are having sex with a woman, and one goes from the behind, and the other in the front. By the law of physics, the sword player's cocks would "knock" each other.
