I am Succubus! or "When I refused to have sex with a succubus, she turned me into one!"
Saeko Ito has only really wanted one thing in his life— to be treated as the boy he is. Unfortunately his friends, club, and even his own sister teases him and treats him differently because of his effeminate features.
One day, his life is flipped on its head when a succubus named Mio not only transforms him into a girl, but into a succubus! All because he couldn't find it in him to "man-up" and have sex with her.
Now he, or rather SHE, must navigate her new life as the opposite gender and find a way to transform back. But as her succubus powers manifest, so too, does her succubus aura which subconsciously attracts people to her. To make matters worse, Saeko's hunger grows with each passing day as her thirst for sexual energy begins to take over.
