Hot Blooded by J. D. Light

Mark and Devon have been best friends since they were ten and completely inseparable since they were thirteen. They were together before either of them presented as alpha or omega, and they’ve been the most important people in each other’s lives without exception these last twelve years. Since they were in high school, everyone always asked if they were a couple, and eventually, they both just started saying yes. In their twenties, not much has changed. Neither of them have had a boyfriend ever, they basically live like a married couple, and most people––with the exception of a few––just assume they’re together.

But among those few who don’t, there is one that is actually stupid enough to try to get between them. When his meddling pushes both men into fighting for each other, the might actually find that they really have been together this whole time.
