This is Matsuoka Kouko's remake of /g/2160002/67815176e6/. The title roughly translates to "A Slightly Disturbed Cure Life". The remake has the same basic story beats with four additional pages and some other changes. For example, the OG release has POV "nut" images of each of the three girls (where the girls are naked, facing and looking at the camera completely exposed, either having sex or not) that the new version doesn't have. But the new version has a more playful, seductive Honoka-chan, which I found erotic. And Nagisa-chan takes it in the ass for the new version whereas the OG version was just normal sex.

If you found this worthy, consider giving the artist some financial support and buying from DLSite. I think it was something around $2 (American). https://www.dlsite.com/maniax/work/=/product_id/RJ366411.html
