This honestly had promise and Harry/Sister is always good, Harry/twin sisters is even better. But...you definitely seem to have written this before you knew what sex actually was...which is kinda sad because it's a bit of a waste of a decent premise. Big is one thing, 2 foot would literally kill someone. So would the other egregious item here. Multiple ways over with that one...

Please update your story soon!

Passy? Nope. Not gonna work. First off, lots of gore. Second, you gotta deal with her shitting through her vaginal cavity, which will cause major major infection issues. That “little” bit of skin between the vagina and rectum, is not little. That’s not gonna tear like a hymen. You’d need to go at that with some scissors and a knife. I honestly have to blank out anything to do with passy and try to rewrite it in my head to make it make sense.

Interesting!

shame this fic is dead

The thing with the "passy" is just too weird and too painful sounding.

Just curious how long do you think 2 foot is?

Is Passy somekind of new fetish that involves gore or something? Im truly confused, never heard of this before.

Over all not to bad but some of the descriptions and parts where just ridiculous... I think you know which ones. Other than that not to bad.

are you going to continue this? would have liked to see a follow up with lily
