Not as bad as I remember and your right about her being enchanted by the MC's cock. However, as a plot point, I'm still a little confused. Why would she be enchanted by his (MC) cock? Isn't the magic in the cum (Corruption) only supposed to make them more open towards sex? It's not supposed to cause addiction or create any kinky behavior, only reveal what's inside, so to speak. Why is it always "...I love the sight of your massive cock" with almost all the girls. I get that the MC has a giant horse cock and that's the main theme of 99.9% of porn games but does the dialogue have to be like that? To me it'd make more sense to have some girls be more guilty/shy/sexually restrained at first, then as you corrupt them they'd be more confident/overtly confident in their sexuality. Feeling less guilty with more corruption until finally reaching whatever desired outcome. Whether that'd be a harem, hedonistic, dom/sub path, etc.
I've noticed that specific story paths get different corruption dialogue. For example, with Tia it has less to do with the MC's big cock and more about building a harem. With Kate, Clair, Emily, Frisha, etc it has less to do with a harem (for now) and more about a big cock and keeping it in the family. I haven't gotten around to the other girls yet, I'm still playing through after the update a while back, so I'm not too sure about the others... maybe I'm wrong about the corruption. I still got to play around with it.
