i can't stop betting on scary board NL50

[sehlooon]

hello, my friend & I disagree about this hand. He thinks it's dumb of me to bet every street, but I'm not sure how else to play it. I figure I had to protect against flush draws on the flop & turn. On the river, my opponent didn't have too many chips, so I figure he'll call with anything.

I have $50
CO has $27
SB has $24

I raise KsQs to $2, CO calls, 1 fold, SB calls, BB folds.

Flop is Qc Jc 6c -- $6
SB chk, I bet $4, CO calls, SB folds.

Turn is 3s -- $14
I bet $10, CO calls.

River is Th -- $34
I bet all in, CO calls $11.

edit: also i played a hand earlier against this guy where he only had a few chips, and he raised all in with the nut flush when he got there on the turn.

This seems standard. Unless you plan to check/fold somewhere. Check/call the turn or river seems like a really bad idea. Felting tpgk for 54 bb can´t be considered a mistake.

Edit: Scrap that, I thought it was only two clubs on the flop, check/fold the turn looks like a solid option.
