Replying...
Intro. She is your virgin younger sister despite being 30 years old and they ended up on a desert island after a shipwreck, apparently it is a paradise since they found fruit, fertile land, animals to hunt, fish, and very few dangers until now... They have been able to bring things from the boat that was stranded near the shore, so things are to a certain extent easy... The first challenge comes when they have to bathe in the river, which scares them. your sister... So she asks you to be there and not stop seeing her so she can help her if an animal attacks her... Such is the paranoia that she decides that they should bathe together.
