Bet this river?

PP 15/30

4 limpers to me, I limp on the button w/ K[img]/images/graemlins/diamond.gif[/img]3[img]/images/graemlins/diamond.gif[/img] Blinds complete and check, 7 to the flop. Flop comes 8[img]/images/graemlins/diamond.gif[/img]7[img]/images/graemlins/diamond.gif[/img]5[img]/images/graemlins/club.gif[/img]. Checked around
to my right who bets, I call, both blinds call and UTG calls. Turn is the 5[img]/images/graemlins/heart.gif[/img]. Checked around to the bettor who bets, I call and both blinds call. River is 3[img]/images/graemlins/heart.gif[/img]. Checked around to me, I check and MHIG. Anyone find a bet here? Is this an automatic call of a bet if MP bets again?
