SUCCUBUS NA KIMI WA OTTO WO OTOSENAI

Succubus na Kimi wa Otto wo Otosenai summary:

Koutaro Tachibana is a perfectly ordinary salaryman, with one little caveat: his wife, Kiyora, is a succubus.
While any man would kill for such a position, Koutaro knows the full story - Kiyo is strict and level-headed, and it’s only when she enters his subconscious that becomes an exhibitive flirty demon ready to suck out his life force. Perhaps that disconnect is the reason why so far, they’ve only made love in his dreams.
Of course, Koutaro loves Kiyo, but he also wants to bring their relationship to the next level too. But what does Kiyo think?
