An "extended one" occurs when two men touch the tips od their erections together and a woman simultaneously jerks both men off at once. (This can also be done homosexually.)
Bro, that chick over there said she'll only hook up with me tonight if we do the extended one. Get over here!

1.A relationship that started out as a one-night stand but turned into a relationship that never should have extended beyond the one night.;2. A relationship that is one-sided in the sense that only 1 of the participants thought it became something more, while it never progressed past one-night stand status for the other-no matter how much time is spent together/how long it continues & behaves like a boyfriend/girlfriend relationship
She thought he was her boyfriend for 3years, even though they had sex the night they met--it was really an extended one-night-stand.
