If you have sex with all 7 of your adopted brothers does it still count as incest?

I just started {Abandoned Girl by Lexi Winston}, and I'm trying to figure out how I feel about it. Haven't even met the brothers yet, but my brain is torn.

If she had kids with them, they would be both the fathers and the uncles. 💀

She didn't grow up with them if that helps. 🤷🏼‍♀️
