Trips get check through twice, did I botch this?

[ISF]

Both opponents here were very loose and relatively agro. Like 50/18/1.5 types. I bet the flop, because I didnt think either had ever folded a flop for one bet, and I figured it would set up a turn CR which they would call even if with nothing, but it didnt work out as planned. On the river I figured he was unlikely to have anything but didnt think it would be checked through twice oh well.
