AK TPTK SB big pot

PartyPoker NL100. Havn't figured out how to get HH's on this site. Lost a buyin earlier to A-high flush holding K-high flush, but other then that, this site is going good. Games seem much softer then I've played on PS.

Anyway, interesting hand comes up. I'm a bit over 100 deep, playing tight, solid poker. 4 limpers, button raises to 5x, I call from SB with AKo, BB calls, all limpers call! Table seems somewhat loose, but this is not the norm.

Flop comes K74r. Gawd. I'm just begging to get stacked here. I check, checks to CO, who's 45 deep and bets 15 into OTB who was the preflop raiser. I'm more worried about being stuck inbetween the deeper stacks on my left, one of which could have easily checked a set on this board.

I call hoping I don't see any action other then folds to my left. Thankfully they all fold. Turn blanks, I put the last 30 in for villain, he calls, I win, I don't know what he had, still loooking for those damn HH's.

Did I unneccessarily put myself into a bad situation here? Should I just muck this preflop with my gawdawful position postflop (SB in a multiway pot directly on the raisers left with an AKo.)

thoughts?

I like it. Maybe reraise preflop depending on your read of initial raiser or how tight/loose table has been. Leading this flop for $15-20 might be a good idea though.
