Future perfect

I'm having a debate with my husband over the use of the future perfect. I wonder if anyone can tell us which one of these sentences is correct:

1) I won't let you read it until I've finished

OR

2) I won't let you read it until I will have finished.

I will be grateful not only for the answer, but also for the grammar rule behind that answer! Many thanks!

The first is correct. , until, when, after, before), it would be rare to find "will" in English, even though future time is obviously implied. Typically the "burden" of indicating future time with "will" or "won't" is carried by the main clause.

The first is correct. After most subordinating adverbial conjunctions, especially of time (e.g., until, when, after, before), it would be rare to find "will" in English, even though future time is obviously implied. Typically the "burden" of indicating future time with "will" or "won't" is carried by the main clause.

Strange:

I'll be in Boston before you will arrive in New Y
