Lilim wants to Lv up♥

After many years of work, I could now say I was able to live a fairly good life. However, I had no goals in life; I just went to work and got off work in an everyday cycle. One day, I took advantage of the alcohol and shouted out to the sky that I wanted a girlfriend—and then, there was actually a beautiful, young woman.

“I’m just a low-level succubus, so I can’t give you what you want. I haven’t even successfully enchanted any humans yet…”

So said Lilim, a self-proclaimed succubus. She said that, as a succubus, there was only one way to level up—and that was to get laid!
Having been single for a long time and feeling lonely, I agreed to take her in for a month, which made Lilim very happy. Looking at her cute smile made me feel a little bit of a stir in my heart. Well, undeniably also in my crotch. I couldn't help but look forward to what kind of an erotic life I would be able to lead later on.

What would become of my relationship with Lilim during these 30 days, and would she be able to succeed in her dream of becoming a high-level succubus?
