The Writer's Visit

The Writer's Visit is a game where you play a dominant, bisexual transwoman who visits her brother while on vacation. Sammy (or any name you choose), a famous erotic novelist known for writing about her sex life, quickly discovers her niece is just as sexually ambitious as she is! It's up to you to use your niece to help grow your harem, while making sure you're the one that remains in charge. You'll need to train your niece and her diverse group of friends to bring in others, and make sure that they not only understand the rules but remain firmly submissive.
