Sister’s Keeper

This is to @dahob’s commissioned continuation of Sister Trouble

Content warning: This is a story about a succubus and her half-brother incubus in a magical dom/sub relationship. Implied incest, sex, and domination throughout.

Ivette, it turned out, was sitting in their shared apartment, reading.

Joff stifled the entirely unfair I didn’t know she could read; she’d graduated from Addergoole, same as him. She was literate and educated, more than most of their peers in in college. Just because she generally didn’t show it…

“‘Vette, what are you doing?”

She glanced up. She was holding a fat highlighter in her mouth – not, the way some girls might, between her lips, but down her throat, as if she was giving it head. Joff felt a tightening in his pants and ignored it.

“Mmm..” She pulled the highlighter slowly out of her mouth. “I’m studying.”

“Don’t lie to me, Ivette.”

She pouted. “I hate it when you do that, Joffie.”

“I hate it when you call me Joffie. Don’t lie to me today.”

She tugged on the thin gold chain around her throat. “But I am studying. See? Highlighted and everything.”

He sat down next to her and looked at the book. “Abnormal psychology? I didn’t know you were taking this class.”

“I sort of snuck into it when you weren’t looking.” She shrugged eloquently. “I was bored in the other classes. Fashion. Bah. So I dropped out of Fashion and Health and started taking Business and Abnormal Psych.”


“I told you, I was bored. You’re not the only one who can, you know, study and stuff. I like learning things, too.”

Joff pursed his lips. “Ivette, stop the poor-me act. For now, at least. Why are you really doing this?”

She sulked, but she pulled back on her power enough that Joff could breathe. “You told me to go to college.”

“No.” He shook his head. “I told you that I was going to college, and that you should come up with a plan.”

“You Kept me, remember?” She tugged on the tiny gold chain. “Being yours is my plan.”

Oh. Was this… no, this was a distraction. He glared at her. “Ivette, tell me what you’re up to.”

“Right now, I’m trying to distract you from asking why I’m studying… damnit, Joff. I don’t like it when you do that.”

“Well, I don’t like it when you leave people half-alive bloody piles of whimpering. So you’re going to have to deal with being told what to do once in a while. Ivette, what is your plan?”

“Well, so, I have to do something. You said. And I’m not really even bad at numbers, but I figured, most of the stock market, most of business, is all a giant scam anyway, right? It’s all psychology.”

“…So you want to go into business? Or into businessmen?”

“You told me I needed a real career first. I still don’t understand why.”

“Because I said so.” Sometimes having Kept his sister seemed like the worst decision he’s ever made. “So. Business.”

“Business.” She waved the book at him. “I am going to slay in the boardroom. It’s going to be so much fun.

“And where does saving yourself for marriage come in?”

He was almost afraid to find out the answer.



There were odder things she could have said. If she’d said she actually was concerned about her immortal soul, that would have been weirder. If she’d said she wanted to redeem herself for everything she’d done in Addergoole, that would have been the weirdest. but this… this was pretty weird. “Reputation?” he repeated.

“Reputation. in Addergoole, everyone knew what I was. Everyone knew I was Ivette, the succubus. Ivette, the slut. Ivette, the man-eater.”

Joff had heard far worse than that, so he didn’t argue with her assessment. “Addergoole is small. It doesn’t take much to get a reputation there.”

“Joff, the pretty. Joff, the victim. Joff, the amazing chef.”

“Yeah. That.” He shrugged uncomfortably. “We all had them. We all had the names.”

“And the Names. Don’t forget those.”

“Vette, is this about…?” Her Name. What Mike had saddled her with, damn him. As if being his sister’s Keeper wasn’t hard enough on Joff without giving her that.

“No.” She shook her head angrily. “No, because I refuse to make it about that. Absolutely refuse. I am not going to be the door that is always open, Joff, the ride everyone’s been on. and nobody, nobody is going to know me that way. I’m not going to let it happen.”

“So you’re… saving yourself for marriage? You’re still a succubus, ‘Vette, how’s that going to work? How long can you hold out?”

“I don’t have to hold out. I just have to not let anybody know.” She ran her hand up Joff’s thigh. “You won’t tell anyone. You love me.”

Joff caught her wrist and lifted her hand off of his leg. “Ivette.” He hated being mean to her, more than most things. But he knew if he didn’t, she’d never get any better.

She sulked. “Joff, you wouldn’t turn me down, would you?”

“I would, and you know it.” He used his best stern voice and the expression that matched. It felt foreign, but it worked. “Behave.”

She sat up a bit straighter and wiped the smirk off her face. “Are you mad at me?”

“I don’t like it when you succubus me.” He released her wrist.

“But you’re not mad about the business thing?”

“That? No. That’s a good idea, actually.”

She preened despite herself. “You think so?”

“Yeah. But.”

“There’s always a but.”

“That’s why I’m Keeping you, big sister. You never think about the but.”

They shared a giggle – entirely inappropriate for the serious conversation, but they were succubi, after all. Then Ivette tilted her head and put on a good business-woman face. “Okay. So what’s the but, master?”

“You call me that just to get punished.”

“Of course I do. Joff, seriously.”

“You’re never serious, Ivette.”

“I’m not normally collared by someone who can handle me, either.”

He sighed. She was back to flattery. “Wrists behind your back. Stand up.” He stood as he gave the orders, and got a handful of her hair. She didn’t focus without this, once she got it in her head that she deserved it. “Up to your room. The but, sister…” He steered her up the stairs, one hand in her hair, one on her wrists. “It’s a good plan – but you’re going to have to stick to it.”

“Really stick to it? Joooooooff, you know you’ll help me.”

He pushed her to her knees, ignoring the waves of lust coming off of her. “Help you? Sure.” He leaned over and whispered in her ear. “No sex for you without my permission.”

Keeping his sadist of a sister, he mused, was likely to turn him into a sadist himself. This was almost fun.

  1. Snorks. I think she made the right decision handing herself over to him, but that doesn’t mean she won’t regret it.

  2. I had no idea what I wanted when I requested this, but this is /perfect/! Great job Lyn! I’ve always liked these characters. So broken
