The act of 2 or more people exchanging their cum with each other. The mouth is almost always involved.

Regardless of gender, regardless of who's cum it is, & regardless of how many people are involved in the cum swap. If the previous conditions are met it is considered a cum-swap.

When the mouth is the sole, or nearly so, source of the exchange it is known as cum kissing. A very similar concept.
Last night after I came in my girlfriend's pussy I immediately ate the cream pie. Her & I then cum-swapped until finally she swallowed it.
