It's chapters like this that make me wonder how capable Nadeshiko is of independent thought and will compared to the influence of her "Mom's" sexbot programming. The whole setup for this chapter was a fake out making us think she's gonna be serious and put aside sex for a moment, only for the "documentary" to just be one of her sexbot functions.
Of course, this also prompts questions about how comparable that "programming" is to any child raised on the ideology of their parents... Either way Nadeshiko could really use her horizons broadened lol. Hopefully she's capable of that, if not then Jun actually would be the better partner.
