Despite the "2" in the title, this is actually a prequel to Futaman 1.
Here we finally see the backstory behind the pervy manga artist and her shortstack girlfriend (?) from Futaman 1. Since they’re both futanaris and this is an Aoba Q Madou book, expect the content to be 10% exposition and 90% steamy futa sex!
Inori is still at it with her kinky hijinks. After she nearly got caught masturbating on the orphanage grounds in the first volume, she decides to indulge her proclivities at a public park a few night later.
But everything she does is to expunge the Devil from her body! She definitely isn’t a massive pervert who enjoy masturbating in public. Perish the thought!
