It's not historically correct but if it's according to the definition of Incubus and succubus then...
Incubus = top
Succubus = bottom
Ikr
Finally, a manga that properly uses the terms correctly.
Incubus = top
Succubus = bottom
Incubus doesn't necessarily need to be males and succubus doesn't have to all females.
Any recommendations that uses these terms correctly cause when I read succubus, I expect them to be the bottom not top.
