Two cute girls that somehow work part-time as a miko and a nun are corrupted by a male demon and become succubi then proceed to dominate and corrupt school. Demon starts the whole thing but this is mostly girl on girl (also futa). There is also some hapless human males getting reverse-raped and drained.

This is english version released by an author.
Japanese version of this work was already posted on this website here:

Author created free game (with english version) that can be played in browser that is a continuation of this story. You can download it from his pixiv page.

Author creates classic corruption stories and posts them on pixiv and fanbox. Office ladies, students, teachers and exorcists become evil and sexy monsters like Vampires, Succubi or Oni. They are pretty good though a bit short when it comes to text.
Some of his works are already posted here so I thought I will add some more. Author recently started adding english translations of his work. Translations are mostly through machine but they are not that bad and it's better than nothing. Below are some links:
