A demon ( or half incubas specifically), Tsubaki, engages in a sexual relationship with his friend since childhood & excorcist, Shiro, in order to help "feed" Tsubaki energy. They're stuck in this this friends with benefits relationship but both want more. Will they or won't they?
Their relationship is super cute. The drawings look like they were inspired by Harada hehe. But it is still doing it's own thing. They can also bea not awkward, especially with the flow, like this is someone's first comic. But it's still good, with lots of work into the many panels on each page. The sex is pretty good too.
Interesting concept, it kept me reading.
