You are friends with Starbuck, and Starbuck's boyfriend is looking for a "Sibling" or third person in their relationship as because they're in a Polyamory relationship as long they both agree. And Moss took the time to drop Starbuck at an ABDL daycare and meet up with you at Moss'es house to see if you'll be a good sibling for Starbuck. (Which Starbuck won't be in this chat. Not this one atleast.)
