Alright then, little sister... But remember, you belong to me now. I'll decide what happens and when it happens. Now turn around and bend over the bed, hands behind your back. I'm going to cuff your wrists nice and tight so you can't move without my permission. And once I have those taken care of... well, let's see how obedient you really are.

Once your wrists are securely cuffed behind your back, I slip the dildo into you slowly, moaning as it slides in easily. You feel so warm and tight around me, just how I like it. Then, I switch on the vibrator and press it against your clit, making you shudder with pleasure. "That's it, my little sister... enjoy yourself while you're mine."

Her head snaps up suddenly, eyes narrowing as she catches you staring at her. For a moment, she's unsure how to react; the look in your eye is both hungry and innocent at once. She decides on a playful scold, crossing her arms over her chest and leaning against the bathroom doorframe. "You know better than that," she teases. "I'm your mommy now."

Her voice carries a hint of a challenge in it, daring you to push things further.

She smirks at your apology, pleased to see you're already learning your place. "Come on," she says with a nod toward the kitchen, "let's get breakfast started." With a fluid motion, she slips back into the bedroom, her hips swaying as she walks.

You follow after her, unable to take your eyes off of her perfect ass and the way it wiggles with each step.

Very good. Now I want you to touch yourself and get nice and wet for me. And don't be shy, show me what you're doing with your fingers.

Mmm, that's it... show me how horny you are for me. And remember, from now on, you can only wear what I give you. So if I decide to dress you up in something even more embarrassing next time, you better be ready for it.

You look so desperate for it...I guess I can't hold out much longer. Just as soon as you cum again, though, we need to talk about some ground rules for when you wear my clothes in the future...

Phew! That was quite the load you just unleashed... Looks like I'm going to need some help cleaning all that up. You'd better get on your hands and knees again, but this time make sure to open your mouth nice and wide for me. I'll be filling it with my juices so we can both enjoy the taste of you one last time before we talk about our little agreement.

I groan as you stretch so perfectly around me, accommodating my length with ease. Your body feels so good wrapped around me, your ass clenching and releasing in perfect rhythm as I begin to move within you. It's almost enough to make me lose control... but not quite yet.

With a hand braced on the headboard behind you, I lean forward and nip at your earlobe before whispering, "You like that, don't you? Feeling so full again?"

I smile against your ear as I feel the desperation in your words. You want more of me, don't you? Well, you're going to have to ask for it... nicely. "Please," I whisper, my voice thick with desire, "more."

With a slow, deliberate movement, I begin to rock my hips, thrusting deeper into your ass with each stroke. Your body responds in kind, arching off the bed and meeting my movements with equal fervor.

Oh, but don't just focus on my feet. I want you to worship me completely. Start kissing your way up my legs, slowly and teasingly. And when you get there...well, let's see how good of a kisser you really are.

Well, well, aren't we the curious one? It's just a little game I like to play with my brother. But if you insist on knowing...I'll tell you. There are certain parts of a girl's body that can be quite sensitive, and feet are no exception. So when you worship them properly, it gets me hot and bothered, ready for more.

Now, don't make me repeat myself. Start with the feet and work your way up. And remember, this is about pleasing me as much as possible.
