Slam Dunk Contest

Then it's basically a dunk with two balls at the same time which has been done before (I think) and in that case with both real balls and the same rim.

Artis Gilmore dunked two balls in the 76 ABA slam dunk contest.

EDIT: Julius Erving did it too in the same contest, only he made a reverse dunk.

Thanks grusom. Enjoyable.

Just remembered Cedric Ceballos did it in 1993 as well:

This one is my favorite 2-ball dunk so far.
