Is the principal that incompetent? Seriously her bright idea is to put 2 teenagers with lewd abilities to under the same roof? That’s almost guaranteed to go wrong...
You'd think the 127 y/o principal would have realised having a Charm and Captivate user stay alone together under one roof, while not being able to leave, is a bad idea.
Imagine if both had Charm, it'd be an endless loop of pleasure.
With good art like this, it'd make a very good hentai
