Hii! there was a book I was reading a while ago that was incredibly well written. The FMC and MMC were step siblings but didn’t really grow up together. Their parents died so he took care of her for I think Junior/senior year of high school. He started spanking her as non sexual punishment but she enjoyed it. He ended up abruptly leaving because he developed feelings and felt they were inappropriate. He lived in Florida? She got a job offer after college there, saw he lived there and met him again. They played and he took her virginity but he didn’t realize she was a virgin and was upset it wasn’t more special for her.

I can’t find it in my archives or any where so struggling to find it.
