This is really really opponent dependent.

A lot of posts here are saying that we must be beat, villain is raising two players. But this is also exactly why this is a perfect spot for a squeeze on this flop (especially with a hand like T9, 89 or FD).

If I was villain I would probably be jamming my draw in this spot, cause I know its hard for both players to continue.

That being said, he probably either has you owned hard with two pair/set or is drawing very live with a combo draw or some kind of FD. I don't think a fold here is awful in this SA/WB spot.
