Given the design on the cover(short skirt with mild butt shot), I don't think the straddling scene from the last chapter should be unexpected here. Anyone who's complaining heavily about it either came to this manga to hate read it, or has truly poor taste in choosing their books to read.
That said I think most people realize its all just writings and scribbles in a book with no actual real Pecorans taking advantage of sleeping men. Also, I'm probably not alone when I say I've always had problems associating 2D anime loli's with actual children ALTHOUGH that drool is pretty on the mark. Its actually considered a real problem by many people(Hayao Miyazaki for one) that Loli's in anime are very poor if not outright false representations of children.
Real children honestly... Suck... Screaming, sticky unwashed hands wreaking you/your stuff, they actually DO wreak your stuff, mind numbing dumb statements, constant whining, a constant need for supervision or else they get lost/hurt/die, and all and out a general lack of common sense. And as a final nail in the coffin they're not even one tenth as adorable as "Lourie". Actually its an argument I have against this book and a good bulk of a lot of the manga out there. Outside of that drooling moment, Lourie doesn't capture any of the traits I've listed above.
Its as if Lourie was written to be a good partner that ACTUALLY could have been 18-21(The age she acts) but was instead given a smaller more diminutive appearance to pull in a bigger audience, at which she succeeded, And then given somewhat adorable skimpy outfits and put into compromisingly lewd poses of which this is the second. But really who am I to list any of the above "complaints" as I have read the entirely of it, enjoyed the book, and even clicked the 9 on the star button. And am even looking forward to future releases!
... Why am I even writing all this? I must be bored... I should do some work...
