NL 50:3 of a kind on flop...what to do with small PP against aggro NIT

[starkwired]

Villain is 14/13/6 over 500 hands. He stacks off willingly postflop with top pair type hands against even obvious two pair/sets.

Did I try to get too fancy? Villain seems pretty straightforward, but is a reg and maybe has it in him to play this slowly. Preflop call is standard, especially this deep, but every other street can be done differently, IMO. Thoughts?
