How did I play this KTo?

[Sandwich]

.50/1 Party ring game. Full table. (10 players)

I get KTo in LMP.

One limper to me. I limp. Button limps. SB completes and BB checks.

Five of us see the flop. K 8 6 rainbow.

SB, BB & EP check around to me. I bet. Button calls. SB and BB fold. EP calls.

Turn is 2, completing the rainbow.

EP checks. I bet. Button calls. EP folds.

River is 6. I bet. Button raises. I call.

results (in white): <font color="white"> Button shows KQ and takes the pot down.

Is there anything I can do differently to maximize my win / minimize my loss here? Was it proper for me to be the aggressor throughout with top pair medium kicker?
