Does anyone fold bottom set here?

[robinmbuk]

Villian is about 25/10, I'm playing at 16/8. No direct reads, but havent seen him getting out of line, and I havent done anything crazy.

NL24, 6max

Villian is UTG with ~100BB
I am UTG+1 with just less than 100BB (missed my chance to reload).

Villian Raises to $1.Hero Calls with 66. All fold to BB that calls.

Flop: 3 players, $3: 687 rainbow.
BB Checks, villian bets $2.5, hero raises to $7, BB folds, villian shoves, hero?

Does AA/KK/QQ/JJ really shove here? Maybe to protect against something like 99? Can you fold bottom set here?
