overcall all 3 streets or would that compensate my manhood?

[TStoneMBD]

villain is 24/13/1.6 2500 hands. my notes on him are "isolates UTG lag from EP with A9o". the calling station is an unknown.

after i was bet into on the flop my plan was to just call down all 3 streets.

after the 3rd king hits on the turn, i was thinking about just going for the overcall instead of raising. id hate it if i raised and the bettor folded 99-TT drawing dead. i also dont think i mind the button calling with Ax.

lets say i just call the turn and the river blanks, could a case be made for going for the overcall or is a raise painfully obvious?
