Take off the Cock Ring... With unexpected consequences.

(Author's Note: No sex in this chapter, but there is some pleading for sex.)

You've had enough for now. You can play with your sister more later. You slip the MCR off and glance into the room. Your sister flops onto her bed, panting. She glances at the place where your cock used to be and frowns. She lets out a slightly dissatisfied sigh. You don't notice as you carefully close her door and head toward your room, feeling satisfied.

You sit in your chair and watch some videos but, about half an hour later, you hear a knock at your door. You answer it and find Kelly standing outside. She's bouncing on the balls of her feet and biting her lip, glancing up and down the hallway. She seems nervous.

"'sup, Kells?" you ask.

She practically jumps at the sound of your voice. "John. Hi. Uhm. Can I come in? I need to... I need to talk to you."

You look at her and raise an eyebrow. You shrug and push the door open. She steps inside and closes the door behind her. She takes a seat on your bed, fidgeting her hands and biting her lip. She refuses to look at you. You take a seat on your computer chair.

"Is everything okay?" you ask. "You're acting weird."

"I'm... I'm having a really weird day," Kelly says. "You wouldn't believe me if I told you."

"Try me."

She thinks about it for a moment and sighs. "No, really. I mean, even I don't believe it. It doesn't matter right now anyway. I just wanted..." She goes quiet again. She glances at you, but then blushes and quickly looks away again.

"Spit it out, Kells. I'm trying to relax."

She glares at you and is about to start yelling. However, she stops herself and lets out a shuddering sigh. "Look. This is going to sound weird. Sick. Totally wrong. But you have to hear me out, okay?"

You start thinking about what you just made her do in her room. You try to think. Could she have noticed you? Is she trying to say she knew it was you? You were suddenly very nervous.

"Uhm... Okay. What is it?"

She struggles with words for a little while. She starts to talk but then stops herself. This goes on for about two minutes. With your own nerves and your patience wearing thin, you give an annoyed sigh.

"Okay, okay," she says. "Don't be such a brat. I just... I wanted to... I need you to..." She mumbles something quickly, then blushes hard and looks down.

"What? I didn't catch that."

She sighs and finally says, out loud, "I really need to lick your dick and fuck it with my ass."

You're stunned into shocked silence. Your mind races. What the hell? Why is she saying this? You think back to the command you gave her through the MCR. And that's when it hits you. You said "Lube me up with your tongue and fuck me with your ass." You hadn't been thinking of your dick at the time. You'd been thinking of you, personally. Maybe your thoughts and commands need to be more specific with the MCR. Now, your sister is compelled to lick your dick and let you sodomize her.

"What," you finally say.

"Look," she says, trying to remain calm. "I know it's weird. I know it's disturbing on so many levels. I know it's against the laws of nature and God and whatever. I know all that. But I cannot, CANNOT, get the thought out of my head that I need to lube up your dick with my tongue and stick it right up my ass. I feel like I have **** in the matter and I really have to do it."

Your nerves catch up with you and you start to laugh, first in short burst, then in a loud belly laugh. Your sister glares at you.

"You think this is a joke. I get it. You think I can't possibly be serious. Let me show you how serious I am." With that, she gets up from your bed and, in one swift motion, takes her shirt off and throws it onto the floor. Her tits flop down freely. She hadn't been wearing a bra.

Your mouth drops open and your laughter dies in your throat. You're staring at your sister's gorgeous titties, her nipples already erect, though you can't tell if it's from the air conditioning or arousal.

"Kelly, what the fuck?"

"This is how serious I am, John." She starts slipping off her yoga pants and panties. "I need to lube up your cock with my mouth and I need you to fuck my ass." Soon, your sister is completely naked in front of you.

You try to speak but you can't. It seems like you're doing exactly what your sister was before. You're like a dying fish, gasping and failing to talk.

She gets on her knees and pouts. "Please, John. Do you want me to beg? I'll beg. I need this. I need your cock up my ass. I have never needed anything more in my life. I know my ass is perfect and I know you'll love fucking it. Just please. Let me lick your dick and fuck you with my asshole. I am literally on my knees, naked, pleading, begging for you to stick your cock in my ass. Please please PLEASE fuck my ass."

You look down at your sexy sister. You never thought you'd be in a situation where ANYONE is begging you to fuck their puckered hole, let alone your sister.

But you have to decide. Do you give in to her pleading? Do you come up with a compromise? Or do you use the MCR to fix this mess before it goes any further?
