I think it is extremly sexy viewing a girl having some bells attached to their nipples and shaking them making some nice ringing noise.
You could use this in kinky games like ordering the girl not to make noise while tickling her every noise she makes she gets punished.
Or you can order the girl to make shake her boobs and make noise every second without noise you punish her.
