Succubi have a vibrate setting. Handy.

I feel like that could actually happen in a certain VN… and I wouldn't be surprised if it did. That would make a certain sweater stuffed with marshmallows very happy…

For real, though, if you don't know about The Reject Demon Toko (even though only Chapter 0 is out), you should – that is, if you'd like the absolute sweetest and oddly really natural feeling slice-of-life-y/action-y yuri story featuring demons, hell, rock'n'roll instrument battles with JoJo Stands, a demon daddy probably somehow related to Aikuro Mikisugi for reasons, a fuckin' sexy badass 'amazon' abs and underboob witch, and, my favorite part (even counting that other stuff), an anime-style VN with an adorably plump girl as the second main character/love interest.

Also the main girl Toko has a bass guitar Stand and let's just say fingering that instrument is probably fingering that instrument. Just sayin'. Also she can strum that thing hard enough set off car alarms down the street and all the vibrating power that comes with it.

…wait, what were we talking about?
