I also feel uncomfortable. So much cringe. I'd rather they just fuck and get it over with. I'm fine with incest hentai. But lying to everyone while openly flirting is just nope. It's inevitable they'll get caught since people know they have a sibling.
I swear the author would be so based if they made a chapter with several explicit sex panels and right then continued with another wholesome episode filled with fluff, like nothing ever happened.
Not sure why I'm still reading this.. I really can't see where their relationship going to beyond flirting and play pretend lovers (well I guess it's in a way rather cute).
There's no way author going to pull Oreimo as well right? Or worse.. turn this into a smut like the author of "Gal Cleaning" did...
