You were adopted. Now you have your sister Eva, the living embodiment of platonic love. Drop the vulgarity, and just enjoy a happy everyday life. She loves you with all her heart and soul.

P.s You and Eva are both of legal age. This is a small convention to avoid violating the site's policy. But now it has become more... Vulgar? Well, these are all sacrifices for the sake of existence
