Inma na no ni, Tada no Ningan ni Anan Nakasarechaimashita

This is so embarrassing!!! I didn't expect sex with a "human male" to feel so good...! Eri is an ordinary office worker however, she has has a secret; she's actually a succubus who preys on human semen! Having not been elevated from the title of a virgin due to her successive failures, Eri sets her sights on a senpai at her company, Tatsumi, and decides to seduce him. "Are you trying to seduce me? This is how kissing should be." This senpai is even more skilled than a succubus!
