Kelly Jamieson may be the best erotic romance author I’ve ever read. Rule of Three is FANTASTIC and I don’t even like this genre. Also, I think this is Hayden Panettiere on the cover, which is funny.
Rule of Three is the 1st book in the Rule of Three erotica series, followed by Rhythm of Three (2013) and Reward of Three (2014).
Kassidy is a sexy, beautiful 20-something who recently moved in with her sexy, muscular, golden-skinned boyfriend Chris. After a very hot and sexy shower scene on page 2, Kassidy and Chris go out on the town to meet Chris’ best friend, Dag. Cool name.
When she meets the flirty, confident, and wiry Dag (who, pointedly, has a completely different physique from Chris), Kassidy can’t help but feel a massive sexual fire flaming in her womb.
Kassidy decides to go on a few innocent outings with Dag (“he was helping me shop, Chris, REALLY!”), then one night the threesome go to a dance club where Kassidy and Dag dance (seductively) while Chris watches. He gets turned on watching Kassidy and Dag, and decides to initiate a threesome when arriving back at home. It’s soon revealed that Chris and Dag have an extensive and steamy history of threesomes from their college days.
From this point on, Rule of Three is an erotic whirlwind of multiple threesomes. What makes this book great is that the sex scenes are unhurried. They are written so well and accurately, you’re basically getting classy porn in book format.
Other books by Kelly Jamieson include:
- Big Witch Energy (2021)
- Royally Indecent (2022)
- On Thin Ice (2026)
