I'm the younger "sister", but my dads only child. I guess you would have to be in my shoes to understand why I feel this way. It may be selfish and I may need to grow up, but this may be something I may not get over. I guess I will have to make my day extra special if that day ever comes for me.
I'm going to give what will probably sound like a snide, trollish suggestion, but truly is not meant to be. Please don't get married until you can put this whole issue into the proper perspective, and not feel the need to do things like make your day extra special to somehow make up for the fact that your dad did something wonderful for someone else, or to somehow best your stepsister. You wedding should be about you and your husband, and not about all of this other silliness. If this is getting in the way of your happiness, then you're not ready for marriage.
