1/2 KK - scary flop?

[ThinkQuick]

A friend starting out at NL would really appreciate comments from the forum.

Hero has KK in MP, no useful reads
Hero has about $150 and is covered by Villain.

Preflop:
3 limpers, Hero raises to $20, 2 LP callers, 1 EP caller.

Flop (Pot size $85): T [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/club.gif[/img]

EP Checks, Hero bets $60, LP1 folds, LP2 Pushes, EP folds, Hero calls (~70 more).

Comments and criticism?
