Ore no Imouto ga Saikou no Okazudatta - Vol. 1 Ch. 5

I wasn’t taking the story that seriously but it does make sense. Reading later chapters makes it fit too well like a red herring. Which is the most likely conclusion imo

Update: Turns out this is actually porn that got inexplicably dialed back for the manga format. Sugar daddy thing is entirely on the table as a serious explanation, even here...

Update 2: The Reveal happens in Chapter 44 of the WN. But not before adding yet MORE layers to the stupid thing. It is dumb. It's implied there's more, and not every question is answered yet (Like why she's got no problem guzzling cum (Yes it's been addressed, and yes, she avoided the question), but bigger secrets have been revealed in this story with less buildup and fanfare.

But to answer the question: I was... kind of right. Kind of. You were entirely wrong, though. The manga made it seem like she was entirely used to all this, which threw us all off. Also she's way nicer here. Somehow managing to keep the cold exterior anyway.

I lost hours of sleep over this, and I'm disappointed. But I promised I'd buy the whole thing if I heard about the trip, and by god did I hear about the trip.

EDIT: Lots of questions answered later on. Not great answers, but, to be fair, it's porn. And real life doesn't always give you neat answers anyway.
