I fucked up. This is my girlfriend's sister. She's been living with us for almost 2 and a half years. A few months after moving in she started a secret onlyfans that she thought no one knew about. I found out pretty quick. I subscribed and for a few months we chatted and she made custom videos for me. She never knew it was me. It only lasted a few months before she got burned out and abandoned it. Since then I never brought it up to her and I only ever told my best friend that she's never met. I've secretly been in love with her this whole time.
