I' say There's 2 way to do it...
Check behind them to see what they'll do on the turn or bet a bit more than the pot to look like a bully.
I would have choose the sedond option considering they both raise and reraise proeflop...
However, they were obviously raising and reraising preflop with nothing!?!? Soo, maybe nothing would have worked... or they are both super reader and they saw you was trying to bring them in your trap!?!?

Nope... I think they are just stupid dummies...
