Testing Mind Control with your sister.

Your sister is about to leave and you'd rather strike while the iron is hot.

You bring the cock ring up to your mouth and whisper to it. "Your mouth and body will follow any order from your brother as long as he says 'Please'. Your mind is free to question his orders as long as you follow them." You then squeeze the ring and it vibrates.

You then start making your way to her room. You hold the cock ring behind your back and go up to her door. You knock on it.

"Who is it?" Kelly says.

"It's me," you answer. "Can I come in?"

"Oh, sure, NOW you learn to knock," Kelly says, obviously bitter.

You enter and find her gathering up some things in her purse.

"What do you want, you pest?" she says as she puts some make up in her bag.

You put both arms behind your back and sigh, trying to look resigned and concealing both hands behind your back. You slip a finger into the cock ring and concentrate. You see your finger poke up from her right shoulder.

"I just wanted to say that I'm sorry about yesterday," you say. "I just... The whole thing was a bit absurd ."

"Invading my privacy isn't absurd, it's sick. And I can't believe you didn't leave when I asked you to."

You slip your finger out, watching your finger disappear from her shoulder. You slip the cock ring into your back pocket and hold both hands up. "Okay. I'll admit it. I found it kind of funny and... actually kind of hot."

She looks shocked and appalled. "John, that's really fucking sick."

"Please say you forgive me."

"You forgive me," Kelly says. She blinks and frowns. "I mean, why should I forgive you? I'm really disgusted by you right now and, honestly, don't be surprised if I bring this up to mom."

You look panicked. "Please don't tell mom. Please never tell her anything we do together. As a matter of fact, please just keep anything we do together to yourself."

She looks insulted. "You act as if we'll be doing anything, you pervert."

You sigh. "Look, let me just start over. Please, hold my hand." You hold your hand out to her.

She reaches out and holds your hand. She looks down at her hand as if it's an alien. You feel ecstatic inside. She's definitely following your orders.

"Please forgive me," you say.

She blinks and sighs. "Look, fine. I get it. I mean, I guess it's been a really long time since you last got laid. I can't be too mad at you. Just don't let it happen again."

You let go of her hand and cross your arms, smiling. "I promise, I'll never watch you buttfucking yourself without permission ever again."

She rolls her eyes and points at her door. "Out, vermin. I need to get dressed."

"Please refer to me as Master when you're talking to me when we're alone."

She glares at you. "I said get out, Master." She blinks. "I meant to say Master. Master." She looks at you, confused and a little scared. "Why the fuck am I calling you Master? I'm trying to call you Master."

You grin. "Oh, Kelly. I think you'll find you'll do anything I say if I'm polite about it. For example. Please twerk your ass at me."

She immediately turns around and bends over a little. She starts to wiggle her butt at you. She looks back, her face horrified as she dances and wiggles. "What. The. Fuck."

You smile. Kelly has always been hot but, despite being your little sister, she's always been demanding, too. It's high time the tables were turned.

"Please stop twerking and turn around," you say. "Let's do something different."

You look at the time and realize you should probably talk to your mom. You frown and look at Kelly as she turns around and stares at you, in shock and some awe.

What should you do? Keep playing with Kelly? Talk to mom? Take Kelly with you to talk to mom? Decisions, decisions...
