i 3bet JTs light, get 2 callers

[tw0please]

Hello, don't have the HH on me but a friend thought I should post this hand from Stars 100NL. Villains are both taggish, BB was running at about 23/20 and UTG was about 20/15. Hero has been pretty active preflop, running about 27/20 over 50 hands or so but hasn't played any big pots. Effective stacks are 100bbs.

UTG opens to $4, I reraise to $14 with JThh. BB cold calls pretty quickly, UTG thinks for a bit and calls. Flop comes AAA and gets checked around. Turn is an 8 or something. Both villains check to me.

1) Should I have bet the flop?

2) As played should I bet the turn?
