NL 25 Flopped set on dry board

[nmt09]

Villan is 13/9/1.9 through 87 hands, no real reads on him.
I know i should raise PF and i normally do but had a big hand on another table and almost timed out. Other than that what do you do here? the straight that appeared would have been a gutshot and I really didnt put him on that.
