Okay, so that anon sold me on the idea of Itachi x Iruka, so I've been thinking about how Itachi x Alpha x Iruka would go.
I've decided that my favourite dynamic is Iruka x Alpha to start with, both of them looking out for Naruto together of course. They met in their mid teens, became quick friends, and then fell in love just after Iruka started teaching.
The alpha works in the hospital as a mednin, Iruka teaches, Naruto is a menace, all is harmonious.
Itachi falls for Iruka first. He gets to know him through Sasuke being Iruka's student and gets a massive crush. It's his first proper crush and he's all confused and doing his repressed hair twirling. He does not know that Iruka is mated at this point.
Itachi falls for the alpha second. He meets them through the hospital, probably as they tend to a teammate of his after a rough mission. And they're so nice and friendly, and they kind of remind him a bit of Iruka. Itachi doesn't think anything of it until he has a very, very sexy dream where both the hot mednin and teacher feature quite heavily.
And then he finds out that they're mated to each other. I don't know how, I don't think it matters, but it causes a lot of very complicated feelings. On one hand, he's devastated, but on the other, he is now confident that they both have likely had sex with each other irl, which is not helping his dreams, night or day.
Itachi is such a mess that both Iruka and Alpha start to notice. They both find it very cute and endearing to watch his stoic face slowly take on a pink blush when either of them give him any attention, only to blossom into bright red when they give him attention at the same time.
Long story short, they get together, and the relationship is just the healthiest thing that Itachi has ever been a part of. Not just the healthiest romantic relationship mind you, healthiest thing involving another person ever.
They are all so cute together!
What do you think their relationship would be like? I'd love to hear some thoughts! :D
