I don't think villain is reraising with 99-TT (though, OP, you would probaly know best). That being said, I gave villain a range of {66-33,75s,65s,54s} and we have 31.7% equity. By adding all 12 combos of two overpairs (let's say TT-99) we are even. Take that for what it's worth, but I really don't think he's reraising these overpairs much. I fold.

P.S. Not to nitpick, but this isn't a flop 3bet.
