I greatly enjoyed this story. Normally I don't like stories where you have a m/m couple and then a female is added, particularly when your m/m couple has been together for years, as I feel like it's saying oh, a gay relationship is okay, but it's better if you add a female. I know that's not necessarily what authors mean to portray, but that's just me. However, this book did it stunningly and I didn't feel like they just added a female to make it a threesome. I enjoyed the formation of the threesome and the exploration of a new sub. This is my fave of the series.
