Intriguing concept for a book

"Spicy story with a futuristic twist. I love the plot of this story, it's a thoughtful and unusual concept as a space travel to restore the human population. The spice content is good but one sided and only doing one or two positions. It ends up becoming redundant. I would've liked to see more participation on the female side since it's a poly story. The character descriptions are also the same exact descriptions in almost every chapter, there's no variation, so rereading the descriptions becomes tedious. "
