This is the ero take on that movie where you press a button and someone, unknown to you, dies and you get paid, but here, someone gets horny and you get laid.
"Something takes a part of me
Something lost and never seen
Every time I start to believe
Something's raped and taken from me, from me…" Yup, it fits perfectly with this story.
The classic Cinderella tale told in hentai form except instead of a glass shoe its remote to a vibrator.
And it just so happens that the vibrator is owned by the perfect and wholesome girl Inoue who's the top student in the school and upstanding moral committee member. But in reality she's a giant secret pervert who can't help herself when it comes to feeling good. Another A+ good girl turning out to be a pervert :)
-when I think about hentai, a chapter like this is what comes to mind.
