This book starts out with an established couple, Loren and Harrison. They are recently trying to explore some kinks, but it's not going well. I think their kinks don't exactly match up, but they don't realize it. I don't think Harrison knows what his kinks are at the start.
They also run a museum together, and they are looking for a chef for their fundraising gala at the last minute, because the original chef canceled. They meet Kody in a bar and they have a one night kinky threesome. As it turns out, Kody is more experienced in kink and helps them figure out how to get kinky together in a way that works for both of them. Kody tells them he is a chef, but doesn't tell them that when he pretended to "meet them" in the bar, he actually already knew they were looking for a chef for the gala.
The next morning, he makes Loren and Harrison the world's most amazing French toast. (He bakes the bread himself, then he makes the toast.) So when they get back home, they obviously discuss offering Kody the gig as the fundraiser chef (without knowing that's what he was hoping for all along.)
They continue to hook up and explore their kinks. There's a lot of cuck kink and humiliating the cuck (Loren). When they're not having sex, the rest of the book has a lot of talk about food, planning dinners to impress the museum board, auditioning for the chef gig, etc. Lots of talk about tasting menus and cooking. Just my personal preference, but I didn't think it was that exciting.
