Cook Brothers, book 4: Hard BackB. J. Harvey2020

Having watched his brothers meet their match, Cohen Cook is feeling something he never anticipated—envy.
With a demanding job, and helping his brothers with their biggest flip project yet, he doesn’t have time to sleep with, let alone date, anyone.
Skye Rossi is a free spirit. She’s a take-her-as-you-see-her woman who works hard and plays hard, but the person she wants to play with friend-zoned her the minute they met.
When sparks fly between Cohen and Skye, the only way forward is to propose a mutually beneficial arrangement that no one knows about.
Besides, what’s the harm in a few orgasms between best friends?
