Speaking of succubus Umi-chan, I think 9chibiru's "Harenchi U&MI" is the only other book with this idea, but with Umi Sonoda+demon girl+futanari+selfcest instead.

@Nasen
That's great news! Thank you so much for your hard work!!

Ooops. Thanks for pointing that out. No idea how that happened.

Also, I already have a scan for 9chibiru's "Harenchi U&MI", just waiting for a translation.
