Ellie still has some bugs. When I whip her, her standard hair will not sit as it is supposed to be. and sometimes she will call a shemale dick a dildo.
som detailed suggestions on the sister:
* customize sister traits:
1. You should remove the question whether she lives at home or for herself since this does not give anything but very little background history.
2. This is how I would make it with as few questions as possible with the most customization:
First question, is she your big sister or little sister? If you choose big sister she is a bit more willful because she is older than you and has more experience (not necessarily sexual). If you choose little sister she is a bit more submissive because you are older than her and you have more experience, so she will at least listen to what you have to say.
Second question, does she like you or hate you? if you choose that she likes you, she has a high Loving and a low Loving if you choose that she hate you.
Third question, how is she towards you? Mean, Sweet or Shy/She did not have much to do with you. If you choose she was Mean towards you, she is more Willful. If you choose she was Sweet towards you, she has more seduction. If you choose she was Shy towards you, she is more Submissive.
fourth question, is she a prudish or Kinky? If you choose prudish, then she has more Submissive and Seduction. If you choose Kinky, she is more Kinky and Exotic.
fifth question (this is icing on the cake but is not necessary), is she a virgin? yes she is, No she has a little experience, No she is a bit of a slut, No she is a nymphomaniac. If you choose yes she is, she starts with 0 Sex Skill. If you choose No she has a little experience, she starts with 1 Sex Skill. If you choose No she is a bit of a slut, she starts with 2 Sex Skill. If you choose No she is a nymphomaniac, she starts with 3 Sex Skill. This question will not change so much on personality or background but will allow for some exciting lines from her.
sixth question (this is strawberry on top of the cake but not at all necessary) what is she? Human, half-elf, vampire, and so on. This question will not change on personality or Statistics (with the exception of Exotic) but will allow some interesting backgrounds and lines from her.
* customize sister looks: give her breasts fixed sizes so you can shrink and enlarge them with potions.
* how sister is when you break her into a crazy nutcase (special break):
1. If you shrink a big sister's breasts down to the smallest before breaking her to be nutty, she will think she's the little sister and you the big brother/sister.
2. have kitten ears on her when a little sister breasts down and she will behave like big brother/sister's pet Slave.
As for the sister suggestions, those are very good but I'm too far in to implement too many changes. The various personality choices mostly just color the dialog here and there. The "live at home" question really means "Will she comment about your parents or not". If she lives at home she might say things like "What would mother and father think about this?" while she won't say that if she's moved out of the house. I also use that to estimate her age. If she lives at home, she might say more younger sounding things while if she has moved out she'll say more mature type things. A sister that is younger than you but moved out of the house will behave very mature, but will still refer to you as Big Brother. As such, "live at home" is one of the more influencing questions instead of just background.
I have added "is virgin" as an option, though right now it's mostly just so she acknowledges the loss of her virginity. I hope to make a pass to use it to influence more dialog and pimp pricing, but it's taken me soooo long to make progress, I'm just trying to finish her up as quickly as possible to make a new release. I still have a ways to go.
As for breast size, you can use potions to change the size, but her starter size is completely in your control at customization time. I'm trying to make all the physical aspects of your sister be in your control.
I love the idea of shrinking an older sister's breast down and make her break to think she's a younger sister, but I'll wait to put that in after a release. If I keep adding things I want, I'll never get a release out. As for a pet slave, she already can break as a docile slave. I love her to break as a "pet" slave, similiar to how Ellie can think she's a kitten, but once again, that will have to wait for later. I love the idea of different races too.
There's so much I want to do and so little time I can afford to put into this (and the sister is currently at 5000 lines and I still have a bunch more to do. This takes me some time :) )
