I think this is a flop you'll see 77 slow played more often and worrying about it is going to be counterproductive. Once you've called that flop raise and the turn, many hands will now shut down especially with that turn Ace. I don't mind your play on either of those streets as I think nearly everything will fire a continuation raise there and shoving on the turn seems like it's asking for limited two pair hands (given this board) or 77 to crush you while you should still be able to get some value on the river versus the more common weaker hands.

This river looks like one that needs a bet.. Fire something he'll think about calling with a solid piece of the flop like a good K, and don't allow him the free showdown I'd expect him to take.
