Zane and his harem of Bodysnatching Demons

What it do for a lanky, sub, like him? Well in Lisa's library there was a book. Nobody knew how it got there, but it did. For anyobody else it was a gibberish it not for him appearently. At least he could read the title. "Art Of Underworld Summoning".

Despite this, and being an public eye, Lisa did not let her borrow it. So he did the stupidest move one could think of:

He stole it.

Yup, but don't worry he had enough sense to write his last rights. Then again, it was in the open in the bookshelf's. Appearently this book was first found not soon after the Cataclysm. Scholars of every era tried to crack it in vain. Since nobody knew of it, and it was "deemed" harmless. Yet the librarian was stingy with it, yet kept it in public space.

He didn't get it.

Anyway, once he was back in humble abode (Shack) that was in Mondstadt, he started to read through the book. There were incantations and detailed instructions of all kind of Demons. From Knights, Generals, to the Succubus, Love demons.

Well, he is a lonely dude, so why not try to latter.

With a chalk, he painted a circle with a star in it on the floor. When he finished he flipped to the page where he found the kind of Demon he wanted to summon. He read the incantation...

Nothing.

...Of course it would be nothing. why did he bother? Sumeru Scholar's couldn't do a thing, why did he think a nobody like him could?

The door to his abode opened. It was Lisa, with a teasing smile on her face. "My my, it seems I was worried about nothing~"

"...You let me stole it didn't you?"

She nodded. "Wasn't my brightest choice. Had a feeling you had a connection to the book with how incistent you were with it and eyed it for the past few days. But overtime my curiousity won and wanted to what it do. Now I'm thankful it's a hoax. What kind of idiot would summon a malicious spirit." Zane fumed at this.

"Now be a dear and give it back to me, and I consider letting you off the hook this time~" He stretched his hand out for her to come and take it.

Lisa closing the gap, stepped on the chalked circle. It glowed Pinkish red. At once, the room was lit and Lisa was paralyzed. Under the floor, it seemed like a gate opened which only let things out, not in. A black smoke exited, and circled around Lisa's form. Said woman was for the first time in a long time was terrified. After the smoke examined her, without any warning, dover right into the mouth. It was an erotic sight for Zane.

As the last of the essence, went down her throat, the bulge that the smoke caused faded as well. Zane was standing there breathless at what did he just witnessed. Lisa stood there for only just a second but then her head snapped at her. Instead of the gemlike green eyes, what stared back was inky black eyes. Which only lasted a second, and her eyes returned to their natural colors. Zane dared not move a muscle as Lisa examined herself taking stock of her new form. As she finished and cupped her own breast Lisa let out a giggle

"My, my what a wonderfull body you have gifted me Master~" 'Lisa' purred. "I'm pretty sure I can dance in this to whatever tune you desire."

"...You're not Lisa are you?" Stupid question, but that was the only thing that could come out of his mouth.

"Hmm, since that is my meatsuit's name may well be." She put a finger under her chin in thought. "But my real name is Lilith, your summoned Succubus."

He frowned. "I summoned Love Demon."

She had a chesire grin on her face. "Same thing darling, we just put on seperate category because nobody would be fool enough to summon a succubus."

He felt cold. Well, getting his life ended with sex might not be the worst way to go.

As if she could read his thoughts she chuckled. "Don't worry Master, you are still my contractor I would never harm you. We threw that book into this world so one day, the world births a person who can summon me and my kind. We give you our loyalty in exhange to walk this plane. Not a bad trade, no?" She walked to him, hips swaying and put a hand to his cheek. "I'm more than willing to answer to your desires~ My kind can easily imitate any person we possess, while also adding our strength to the vessel."

Her hands trail down to his pants. "I see you desire me, this wonderful body~" She unbuttons it. "Let me ease you for what is to come."

And so Lilith or 'Lisa' started rubbing his balls. Kissing his rod from the base to the tip, He was fully erect and started to fuck her mouth. Once he came he drank all his cum with one loud gulp.

"Oh yes, life will be good." Zane muttered. He is tuckered out, and Lisa snuggled into his embrace on his bed, naked. Tomorrow he will plan how to proceed but now. He enjoys the gift he got
