Is there a sequel or prequel to this? It's tagged 'multi-work series'

Page 15 has some overlapping japanese text.
Page 21 has a weird line next to "took".
Page 27 has "she he".
Page 28 should probably use "was" or "would be" instead of "is".
Page 48 is missing a pronoun.

@AkaiKurai
you know, I'm not actually sure. It's just that Ishimura's tentacle plots and character designs are so similar that people assume so with the way this one is written. The magical girl in this one looks very much like the girl in http://e-hentai.fbk.tokyo/index/g/1485547/d95026a0c6/ , but that was a miko and not a magical girl.

Main girl from this one almost certainly was already drawn several times by Ishimura, one over three years ago. Pretty sure though those were only a single page drawings.

One of the seemingly unspoken rules of hentai I've noticed - though there are exceptions to this - you have a higher probability of avoiding a bad end in a hentai if you're already accustomed to doing the deed (or in this case shoving stuff up your butt) cause you have a higher fortitude for it.

Man's the king of anal doujin.

A corruption doujin that blueballs you on the actual corruption transformation, booo!

There just isn't enough mouth / throat modification out there. So good.
