Omegaverse - trying to decide if it’s non con

I have read a lot of OV books, and usually there is some level of getting to know each other, she invites them into her bed etc… even if insta love.

I am currently reading one where everyone involved is just a slave to their instincts that there is no conversation, there is no question, there isn’t any preamble at all just random “come here omega and ride this cock…”. Which don’t get me wrong, I am all for free use vibes. But these people barely know each other. The first instance was one of the guys randomly showing up at her house to give her something (he only met her once before) and suddenly he’s in her house and talking dirty to her, eating her out, cumming all over her and marking with his scent. She didn’t even invite him in.

I am struggling on if this is just this omegaverse universe or if this is really more rape / non con… thoughts?
