You are not the first nor I suspect the last, to do a "Bachelor Party" story. Neither are you the first to apologize for starting one and then finding Jeconais' story.
Rest assured, that even if we have all read the others, even if they are nearly the same. I still want to read yours :)
Please update, I found the other stories to be kind of short and unfulfilling, it will be nice to see the girls fight for Harry's affection.
