Poker Stars, $0.10/$0.25 No Limit Hold'em Cash, 7 Players

SB: $18.90 (75.6 bb)
BB: $8.21 (32.8 bb)
MP1: $43.17 (172.7 bb) <<< 64/5 over 22 hands 1 tabler aggression 0.3
MP2: $9.61 (38.4 bb)
Hero (MP3): $41.34 (165.4 bb)
CO: $25 (100 bb)
BTN: $25 (100 bb)

Preflop: Hero is MP3 with K Q
MP1 calls $0.25, MP2 calls $0.25, Hero raises to $1.25, 4 folds, MP1 calls $1, MP2 calls $1

Flop: ($4.10) 5 4 Q (3 players)
MP1 checks, MP2 checks, Hero bets $3, MP1 calls $3, MP2 folds

I b/f for value.

Turn: ($10.10) 7 (2 players)
MP1 checks, Hero bets $7, MP1 calls $7

I'm unsure what sizing is best here, Villain takes the c/c and check turn with pair of 10s, Qs, Already made flush and flush draw.

Still b/fing of course.

River: ($24.10) T (2 players)
MP1 checks, Hero bets $6.75, MP1 calls $6.75

I believe Villain takes this exact line with all hands I listed above, I felt if he has a pair of 10s or Qs He'll call 1 more street, I'm still obv b/fing but was confused on what size I should go for OTR as well.

Besides sizing, look good?
