What I think is, apart from being jealous in some ways, Kami is afraid of Heidi. She has the same age as her (25) but Heidi is far ahead in term of "social" behavior. Kami is afraid of the world, and of the world she is working in. She manages it, being courageous, but still, it is not her world. Heidi is more mature, more experienced, not scared at all. When she heard the price of their trip to Geneva the "boyfriend" of Kristy was paying for, she almost fainted, fearing what it could imply (i.e prostitution).Heidi talked a lot to Kami, and Kami took the bet. (At the end the trip was very nice and the girls are very happy)
Kami is a nice and good girl. She is not sex shy, she likes sex, even with girls, but there are a few things she doesn't want to do and that hurt her - things that Heidi don't care so much. Kami is certainly a bit naive and she is not able to think a lot by herself, she is very emotional, does a lot of thinking with her guts only. She is a strong fragile girl - Kristy is certainly more brainy.
She knows from her teenies that she is special, beautiful in many ways, a princess as Kristy said about her, but the world is also mean to this kind of girls and they have to be real tough. So she is looking for people to protect her - she said that about what she is looking in men -, Dima is doing this job - I don't like the guy but he is always present for her. Kristy is doing the job also. When Kami travels alone she is really suffering, scared.
Kami is like a jewel going around without security.
I don't know the people behind RLC. But what I saw seems to me that they are pretty decent and nice. They are doing soft porn with amateurs and try to protect them - I think those at the origin of the project are fairly educated.
Did Kami was consulted before letting in Heidi ? I don't know, but I think she couldn't refused. Heidi was in the need of a place in Moscow, Heidi was her friend and Kristy's friend and herself (Kami) was more and more away from the apartment. They could have told her : Ok, you go away as much as you want but we need another girl in this apartment.
I like Kami a lot - everybody here has understood it -, because she is very human : very strong and very fragile. Apart from having a beautiful face, a beautiful body and a warmness only Russian can afford to have, it seems. (Read Dostoievsky). So we must enjoy her presence, look for porn elsewhere, and be thankfull to be able to meet such a girl through internet. I just hope our support can help and protect her.
