My actual sister is ugly as fuck and I have no desire for her. However, here is (roughly and undetailedly speaking) all the siblings in my fantasy world. (Bear with me as the plot is a bit complex and autistic, I will at points mention characters not even in the family for understanding's sake.) Also worth nothing when I say a character is 'based' off someone what I mean is that they look like them and maybe have a few mannerisms taken from them; not that they are in any way similar to the actual person (I don't really follow celebrities so I wouldn't know anyway)
Background
My mother and father are killed, and me and my sister are adopted by a step-mum, who is already looking aftetr my other estranged sister and my two half sisters.
Chloe
(based on Chloe Grace Moretz) is my younger sister by two years. After my original parents died, we follow each other into the Establishment's (basically a distopian feminist government) Orphanage until we are adopted by my step-mum. She is shy and cute, and we become closer than anything.
We start kissing and making out etc at a young age when we both enter puberty (around 9), and start having sex after Emma (see below) teaches me how at around 13. After which, we have a very close relationship (retaining intimacies even when we each have girlfriends), until she is killed by Taylor (see below) for various reasons, one of which being in order to subdue me under her will.
Lila
(Based on someone I knew irl who I won't post pictures of) But her description is, she has firey red hair, green eyes, pretty, largest breasts of all my siblings and about 5"11 (my height). She is my half-sister (same dad, her mother is my step-mum) who is the same age at me. We are therefore in the same year at school, and at first share a pretty indifferent relationship; we sometimes acted as friends (especially when Chloe and Emma are around) and sometimes she was abusive (with Avril). Eventually we do become solid friends, and evolve to have a proper bf/gf relationship (due in part to the encouragement of her best friend and Emma), which, after realising we can't be as public as we'd like, simmers to a private relationship retained through my and her's other relationships (like with me and Chloe - we even often have threeways with her, as well as once or twice with Emma).
However, shortly before the death of Emma and shortly after the death of my step-mum, I accidentally impregnate her, and after the Establishment becomes aware through secret blood tests, she is kidnapped by them (as incestous relationships are illegal and incestous children even worse) and has been missing since.
Avril
(Based on Avril Lavigne) is my elder sister by two years. She was adopted by my step-mum when she was young and resultantly takes her side and despises me (my step-mum is abusive, but this is about the siblings), busting my balls and frequently humiliating and bullying me throughout my childhood, generally being a bitch. She even castrates me twice at various points (testicles can be reimplanted if due cause is given, for example the need to breed the male, but I didn't know that at the time). There is a brief period where we ally as I begin dating her best and only friend, but afterwards she remains abusive. After the later death of Chloe, my step-mum, and the disapperance of Lila we bond out of loneliness, eventually having sex and joining forces (along with other characters) to fight the Establishment undercover.
