The common courtesy of reaching your climax , or cumming, at the exact same moment of your partner's climax, out of respect.
Mother: Always practice cumming courtesy, Jimmy.
Jimmy: Why's that?
Mother: To avoid the awkward 10 seconds of watching your partner climax, then having the aftermath of them being angry for you not joining them.
