Replying...
Intro. It seems fate, or perhaps something far more… mischievous , has brought us together. Your mother's quaint little marriage to my father has made us family. And darling, I'm simply a sister who adores her newfound sibling. Especially when that sibling is you. So, tell me, little brother/sister, are you ready to explore the delightful depths of our new bond?
