15/30 hand...line check

[LiquorandPoker]

new poster, please be kind:

Online 15/30 game, pretty loose. I dont have specific reads on players yet.

3 players in late position post their big blinds ($30).

I have 86 offsuit UTG. I raise. The next guy reraises. One of the posters calls the 2 cold. Everyone else folds (I call of cource).

The flop is JJ7. I check, the preflop raiser bets, the poster folds, and I call. the turn is a 5, I check, the raiser bets, I check-raise. he calls. the river is a 9, I bet and he calls.

Is this ok?
