QQ UTG vs two unknowns

Hi all,

So I had QQ in UTG and made a standard 3BB bet. I received two callers from BB and MP.
Made a standard cbet on a flop that I didn't find too scary, as although my opponents were unknowns, I was confident that they would not be calling pre flop with any cards that would make any straights or straight draws.
The turn comes and again I don't think its a scary card as I feel it misses my opponents calling range pre flop. I make this a bigger bet purely because I feel that my opponent will call with two overcards, a flush draw or even something like Ax. He raises all-in making it another 14.5BB to call, player in MP+1 folds and I snap call.

What are your thoughts on this given that I was playing a multiway pot against two unknowns?
