Do I raise again? Just call? fold because he must hold a set?

Read UTG+1: Vol put $ in pot= 36%, PRF raise = 0% (42 hands PT)

No reads I suppose I just call down unless you're sure you're drawing to two outs. 88-JJ make this play a lot too.

[Borax]

I thought about calling raising, pushing and folding here.
I am affraid of a set or a straight here, but 55, 88, 99, TT and JJ is very possible holdings I would say. So I decided folding would be a bit passive. but try to call it down, raise or push is the mian question. If I call, do I fold to a big river bet?

[los_toros]

I'm not sure if raising folds out other overpairs, so I'd call down.
