False Double Foul with Held Whistle

[NewNCref]

College Intramural Championships. Fed Rules.

As Team A is driving toward the basket, B6 (on the bench) screams at me (I'm C) "When are you going to start calling some f***ing fouls!" I hold whistle until play is over, but it end with a shooting foul committed by B1 on A1.

The question is, this is a false double foul, but how do you administer the free throws? I know you do it for the foul that occurred first, so I reasoned that the T actually occurred first but the whistle was just delayed. I am R, so U1 and U2 come to conference about what to do. We gave 2 shots for the T with the lane cleared, and then put people on the lane for 2 shots by A2.

Is this right?
