MC has some serious self-control dealing with these twin succubi, though I really hate that blackbox censorship in the middle of the chapter and are we getting a secret seggs scene next chapter?

it makes it more likely, way more...
How come Hayato wasn't puzzled by those strange black boxes? You'd think he would first rub his eyes to make them disappear and when that failed, try to touch them to see what they are all about.
