Folding an over pair in 2/3 Live?

UTG +1 $450 (hero)
CO $600 (Villain 1)
BB $300 ( Villain 2)

Hero has KK raises to $15
fold to CO
CO calls
BB calls

Flop: 10 7 4 rainbow
BB bets $20
UTG+1 raises $50
CO moves all in
BB calls
UTG+1 calls

Board runs out Qs Qc

CO turns over pocket 7s for the full house
BB turns over 10 9o

I wasn't worried about the BB as he was more of a fun player but the CO was a good reg.
Am I right to call off all of my stack with just KK after 2 players move all in?
