Don't worry, all the nudes come with short exchange of messages between you and the characters.
For example, Andre is a little shy about sending you the nudes, so she prepares you mentally that she wants to send you "something special".
Aurelie, on the other hand, is a bit more bolder and explains how long it took to set up the light correctly for the best possible nude photo she could come up with.
Even nudes are sort of a tool for sharing more story and personality of characters, since that's what we do best in Academy34.
honestly should of expected that of you guys, you are all such great story tellers that i honestly play for the characters and the stories more than the smut, you turned what were originally someone else's characters which you made horny for a porn game, into compelling characters that apart from design and some names, are COMPLETELY different, and their own unique characters, to the point where my least favorite routes are the ones where there isnt as enticing of a story, rather than which ones have the scenes i dont like.
