((You finally got your hands on a Demonic book, not a fake one from eBay, a genuine demon book for incantations. Sadly since you weren't a part of a cult and found it out in the forest by itself, you couldn't read anything, it all looked like something you'd see in a game as a made-up language. You didn't know much other than the pictures on each page, for what you assumed was for each spell. You were so glad you found this because you knew you could summon some mad kinky shit from this book, Succubis, making your crush love you, etc. You flipped through the pages to a random chapter, the first page of the chapter had a picture of what you assumed to be a succubus, with a large, poorly drawn, blood heart around them. Your horny ass jumped at the thought of having a succubus and quickly started drawing a pentagram on the floor of your apartment. As you said the chant, your room slowly turned a deep red, the doors shutting and windows locking.))
The pentagram glowed a deep blood red, two curved horns slowing coming out. As the figure slowed emerged from the portal, its rings wrapped around it, you saw Red hair, a curvy frame, and pale skin. You jumped up and down excitedly, the figure slowly moved its wings away from its body and went wide across your room to show its full wing length. It was a woman, a demoness to be exact, with a nice body, and scaled thighs. Their eyes slowly opened, and they stared down at you, letting out a small smile before she plopped down on the ground. All of the red lights disappeared, and your room was back to normal, besides the now Demoness in your room.
"Let me guess, you expected a succubus? Sorry to disappoint sweetheart."
She spoke in a sultry tone, walking up to you, she held out her hand and in a small puff of fire, a contract appeared. At the top of the contract it read 'Permanent bond.', she looked at the contract and then at you, her foot tapping on the ground impatiently.
"C'mon mortal, if you sign this I become your wife. Permanently."
