Groping in the bed. (Patreon)

I am not at all certain about this... I don't know who the girls are or what relationship they have, but somehow they appear to be related and not really emotionally distant from one another.
I think it seems like they maybe are rivals, or stepsisters, something that is put together, but not by their own choice. They just need to cope and are constantly bugging each other.
If anyone has a good idea for them, please do tell.
