The Mind Spear Chapter 17

Cathy proves to be a good sister

Cathy stands naked in the bathroom and bends over the sink to check her discreet make-up. Her finger runs over her lips and she flinches. Her body bears clear marks from sex with her brother. Her breasts hurt and, like her legs and arms, are bruised. Her lips are sore, as are her labia, and her bottom is clearly labeled as his property by hand marks. But Cathy smiles at her reflection in the mirror.

She skips all her classes at university today, somehow she suspects that education is not what Ethan will ask of her, and instead spends the time on something she didn’t think she was capable of a few days ago.

The internet is a good source for the things she needs to learn and at first it was strange, then she found it very hard not to press her hand between her thighs and desperately finger her ever-wet snatch as she searched various porn sites and read up on sister porn online. Only once had she been shocked when she realized she had no control over her body, then she had focused on how she could be the best big sister for Ethan. It wasn’t so bad if she considered the fact of being a slave as something as natural as the sunrise. She knew she was enslaving herself, but the pain was gone and she knew she would continue to do so.

Now a nervous girl looks back at her in the mirror, trying to be submissive yet independent enough to make her little brother proud and pleased with her. But she will succeed.

Because Cathy has learned something new about herself. Yes, she is terrified of the worst pain she will ever feel, but she has realized that she is finding it easier and easier to strive for a mindset that protects her and pleases Ethan. The euphoria after the shocks, when she has managed to think the way her brain tells her to, submissive and supportive, is addictive. The feelings of happiness that arise when the pain stops and she realizes that life under her brother’s control is possible makes her try. And it works. Yes, she gets shocked from time to time, but if she sees that pain as a reminder to be a better person for Ethan, then she wins too. And she hopes that her brother will like it.

She looks at her watch. Ethan should be home soon. She quickly puts on a black bra – Ethan seems to like that, ripping the things from her big breasts – under her long white shirt and a pair of tight jeans that only come down to her lower legs. She checks one last time that the clothes can be taken off quickly, then hurries into the living room, stands in front of the door and waits for her brother, the paniced beating of her hard only soothed by the wetness between her legs.

“Welcome home Ethan… oh… oh no…”

The black eye and sore cheek are not a pretty sight but what hits Cathy the most is the blank look of resignation she’s seen on his face so many times before and ignored. But not now.

“Jason was there too,” he says simply and Cathy can no longer contain herself. With a pained look, she takes her little brother in her arms, all thoughts of slavery and sex gone and it feels good, natural, to give her brother comfort.

“Come in little brother.” She leads him to the sofa in the living room while holding him in a feminine way.

“I gave her the second load.” Cathy sees the cartridge for the first time, sees two red and two green bars on an electronic display. This is the device that has made my life so… so much better. She is not shocked. It looks so unimpressive in his hands, but Ethan looks at it like it’s poisoned. “I didn’t mean to. It was a reflex.” His voice is monotone, no trace of the determination and self-assurance Cathy’s torture and submission has brought out of him. And Cathy gets angry. She’s his big sister and she should be making sure he’s happy. And this girl was watching him get beaten up? “She thought I stabbed her with an Epi-pen or something and Jason made fun of it.” He waits for a second. “I’m not going to activate it.”

“Yes you will,” Cathy hears herself say, now crossing the line completely. Her brother looks at her, puzzled.

“What?”

“You’re going to activate the spear. Like you did with me.”

“I love this girl Cathy. I can’t…”

“Shut up and listen.” Cathy blinks, Ethan does too. But the shock doesn’t come.

“Okay.”

“Thank you,” she says, relieved. Then she puts her hand on his shoulders and talks to him from big sister to little brother. “Ethan, I’m a bad person, we both know that. And you make me better. Against my will, but look what you’ve done to me in such a short time.” She takes his hands, places one on her breasts, the other on her cheek. “It’s not so bad being a good girl for you. You see? I’m already thinking in a better way. And let me tell you, Jenna’s a bad person too. She could have just said ‘no’, could have called Jason back, could have defended you.”

“She laughed.” He looks hurt, like he’s going to be shocked himself. Hurt, unsure and depressed.

“I would have done the same before you made me better. Don’t be afraid to cause her pain. You weren’t afraid with me either. The pain is bad, but you have no choice but to submit to you and look at me. What comes after the pain isn’t so bad.” And Cathy enjoys his fingers moving against her breast. She tilts her head and nuzzles his hand.

“She has so much potential…” he admits shyly.

“And you will free her potential. And Jenna will thank you for it. Trust me with this.” Cathy leans forward, gently pushes Ethan onto the sofa and swings herself across his lap. “Just think,” she says as she unbuttons his pants “how happy she’ll be with you once she thinks the way that’s good for her.” His cock comes free and she grinds her hands firmly around it, starting to jerk off. “The way you tell her. Think of the looks she’ll give you.” She holds her long hair and lets a blob of spit fall onto her hand and his glans. “You decide if she looks at you in love or fear. Or both. You make her feel good.”

“Cathy…fuck…” His hips move toward her and Cathy grins with satisfaction. He wants to hurt and fuck me so I’m a good sister to him. Yes! She leans forward and kisses him on the mouth, intimately and lovingly, then hot-bloodedly.

“And now you’re going to fuck your big sister in the living room. Let me take your mind off it…” She smirks. “Master.”

“Fuck…”
