My best friend made damn sure I knew the rules. His sister was strictly off limits. Until now.

Growing up, it was always the three of us. Me, my twin brother, Kyle, and our best friend, Aiden. We were inseparable all the way through high school.

Did I picture myself with Aiden from the first moment I laid eyes on him back when we were eight? Hell. Yes. I fell in love with his soul that day. But he was always more Kyle’s friend than mine. And Kyle made damn sure we both know the rules.

I was strictly off limits. Forever.

But now, Kyle is gone. Dead from a freak accident. And Aiden is still here. Looking hot as hell in his grown-up body. Looking sexy AF with those tattoos all over his muscular chest. Sad and in need of comfort. Just like me.

Every time Kyle caught me lusting after his twin sister, Kali, he reminded me of the rule. "You were my friend first."

If you want to get technical about it, I was Kali’s friend first, not Kyle’s. But that’s not how he saw it. One rule. That’s all we had between us. Just one. Stay away from my sister.

All these years, I’ve honored that. I never broke his trust. Until now. Because he’s dead. He left us. And being with Kali is the only thing that makes the pain go away.

I want Kali. I want to marry her, and have kids with her, and keep her in my bed forever.

But I want Kyle’s blessing, too. And that’s something I’ll never get.
