.25-.50 PL Live - Combo Draw

[FireStorm]

.25-.50 PL Hold em, live, at someone's house. Actually a fairly idiotic game in which the buy in's for this game are capped at $20. (I realize this is terrible and obviously makes for bad poker. I usually play in clubs where buy ins are standard, this game is more for fun, as I went in expecting to see stupidity).

Not too long into the cash game, pickup Kh7h in MP. After a couple of limps, I limp (bad), and we get to a flop 6 way limped.

$3.
8x-5h-4h. Villain 1 leads out for pot from the BB. Folded to me, I call (raise here?). Villain 2 to my immediate left pops it to $14. Villain 1 quickly coldcalls $14. Hero .... ? Forgive lack of HH but I have something like $18 behind at this point.

Villain 1 is actually my g/f. I taught her to play, she is pretty tight and ABC. She doesn't overvalue hands or get out of line. She has led out with draws in the past.

Villain 2 is another club player of whom I have a good impression. Seems like a knowledgable player. I don't a read that this is a move or overplay of a marginal hand.
