The black fog and purple lights held him in their grip for a while longer, and then they dissipated. Stumbling to the floor naked, he managed not to hit his elbows against the carpet, but he wound up on his hands and knees. There were bookshelves all around him, and a few feet in front of him, a pair of shiny black boots.
"Oh good," a lady said. Her voice was calm and silky, and she was sitting in a big, ever so slightly fuzzy gray recliner. He looked up past her long boots, and past that, she was wearing nothing but a set of latex underwear on her pale body. An elaborate heart-shaped tattoo rested just above her panties, and both dread and arousal filled him as he got an idea of what she was. Catching a glimpse of her stunning violet eyes as they finally bothered to glance at him, he looked into them, half in fear and half expecting her to say something.
"Mhm, yes, you'll do," she said, nodding without much of an expression. Too afraid to respond, he kept looking at her; his gaze was drawn to her lovely chest at first, but then to her black wings and horns. The warm light from above glinted off her wings, spread gently out from her back and sticking out to the sides.
Still on his hands and knees, he didn't dare to move from his position. After being whisked away by that cloud of glowing magic that ambushed him in his bedroom, he feared what else she could do. The wings, horns, and then the tail with the bulb-shaped tip he finally spotted behind her... He heard things about succubi, but never took their existence seriously. He looked around more; her recliner was nestled in a cozy corner of a massive, windowless library, warmly lit from above by bright chandeliers. To his left was a wrought iron railing, beyond which was the library's lower floor. He almost thought of jumping to escape.
Instead of saying anything, she reached over to the table to her left and picked up her laptop. She set it on her lap and unfolded it, disregarding him; the table on the other side had a book and a cup of what was probably tea.
It felt like she was just on the brink of saying something for several seconds that felt like forever, but eventually, he mustered up the courage to say something on his own.
"Ummm... What's happening?" he said, praying she wouldn't do something horrible to him.
She picked up her tea and took a sip. "I just wanted to relax in my library for a while with some tea and a snack. So I summoned one." He shuddered as she called him that. Unless there was some cake hidden out of view...
She typed a little on her computer, then looked back at him. "You can wander around if you like. I prefer to let my meals sit for a while." Then, she was back to typing.
Snack. Meal. Succubus. He only had a vague notion of what they did to their victims, but it began to sink in that he was about to be one of them.
"I, uh, please don't kill me..." he muttered, quieter than he thought he would.
She didn't respond; instead, she just looked at her computer screen, sometimes scrolling. For a moment, he wondered what she was even looking at on there, but then all his other concerns came back. He tried speaking again.
"Are... are you going to kill me?"
Not a single reaction flickered on her face. She still typed away as if she didn't hear him at all. Although he was naked, he still felt himself heating up from what was probably fear and uncertainty; then, as he thought about himself, it occurred to him that he was still on his hands and knees.
Cautiously, he stood up. She didn't smite him to ash with magic as a small part of his brain expected her to. Even from his normal height, she was still imposing; her violet eyes looked like they could kill him with a glare. And worse still, even slouched on her recliner, she was so hot...
Why was he staring at her thighs? He tried to look away, but wound up gazing into her chest instead. If she noticed him doing it, she didn't care.
Not wanting to provoke her anger--if she was even capable of feeling it--he didn't ask a third time.
"Um..." he stammered. "I'll wander around, if that's okay with you..."
"Go ahead."
Maybe he could find a way out? If she didn't care that much about him, maybe, just maybe she didn't care that much about this place's security... He slowly turned around and began to walk away, wondering what all she was planning on doing with him. The possibilities cycled through his mind...

He wasn't sure if the library was part of some palace or something; or if he was even on Earth anymore. Maybe deep under it. That seemed more likely--none of the books were written in any language he understood. He was afraid to take one out of its proper place on the shelf and examine it, but when he made it downstairs, he finally succumbed to curiosity and gave the inside of one a look; it was gibberish to him, though all the bullet points and lists and pictures of plants inside made him wonder if it was a cookbook, or even a spellbook. He put it back.
It didn't take him long to make it to a pair of polished oak double doors that seemed to lead out of the library. He tried to reach for the doors, but an invisible force repelled his hand as it came within an inch of the brass knobs. He pushed harder, and so did it. He tried as hard as he could, but it just made him slide backwards against the carpet.
Then he got an idea. When he tried to touch the doorknob with a book, it was able to make contact with the doorknob: the aura seemed to only repel him alone. With a little finesse, he gripped it with a pair of books and turned it, pulling the door back towards himself. He finally opened the door, glimpsing a dim marble-floored hallway beyond that ran to his left and right. There was hope; his fear vanished for a moment, and he looked behind himself one last time before darting towards the opening.
Then, when he tried to go through, the invisible force shoved him back, and he bounced backwards and almost fell to the ground, dropping both books as he caught his balance.
With his hopes dashed, he put his books back and started looking for other options. Remembering that there weren't any windows, he wondered if there was some other way out...
Just as he was thinking about secret passages, he felt something enter his mind; his vision blurred for a moment as he heard that succubus's voice echoing in his head.
"Come back to me. I'd like to feed on you."
His body obeyed her command, even while he was unsure if he should try and force himself out through the barrier or submit. His legs quickly moved him along, taking the most efficient path to the staircase. He couldn't control a single part of his body as it obeyed her. And, that presence in his mind was still there... Was she reading his mind? He had no idea. He tried to suppress his thoughts of escape and failed miserably.
