This is a specific situation that happened to me and I'd like advice on how to play this situation. 8 players in a $25 max buy-in ring game. Early in the game. All are average players. Button is semi-loose preflop and aggro post, but definately not a shark.

Your in CO with with KT off, it's folded to you, you raise 3xbb.
Button calls, blinds fold.
Flop comes KT5 rainbow.
You have top two pair, and are first to act.

What I want to know, it how would you play this hand in a way to find out that the guy in the button has pocket 5s. Is it possible, or do you always pay off the trips in this situation?

How would you play it differently if the guy was tagg?
