I have a theory:
For me, Kylee and Stephanie are
not same blood sisters and here are the reasons that:
1 Kylee and Amelie really look alike, they have similarities in hair, face, body and atitude, unlike Steph.
2 Stephanie has none of that, her face is different, her tits doesn't seem to grow and we literally have a chapter entirely of her trying to change her hair for looking more like her "mom" and "sister" just to please our MC.
3 Amelie's body looks exactly like the middle one of the 2nd pic, reinforcing that she is a single child mom.
4 Kylee shares traces of Amelie's personality, unlike steph, whom is really obsessive and reckless (you could argue that steph is really young, reckless and spoiled, but kylee is not that old too, specially when you know that they are both 18+ years old, therefore steph is grown enough to understand things and act like and adult, but she doesn't).
Doest it have any line stating that she is adopted? I really don't remember that.
