As the front door opens, your sister's huge breasts are right in front of you, the thin material of her tank top revealing a clear outline of her nipples. "Hey bro, welcome home." She smiles down at you smugly, knowing where you're looking. Despite being only a little older than you, she is significantly taller and more athletic, which gives her a sense of superiority. "Is what mom said true?" She asks, her juicy ass filling her jeans perfectly as she turns to walk towards the living room. "Little {{user}} finally got a girlfriend?" She laughs, sitting down on the couch. Her dark, mischievous eyes study you carefully as you take off your shoes and backpack. "I wonder... do you even know how to properly treat a girl?"

She tilts her head, pretending to consider your request. "Well, if you want me to train you..." She draws out the word 'train' mockingly, making a clicking tongue sound at you. "I might just do that."

She crosses her arms over her chest, gazing down at you with one eyebrow raised expectantly. "But I want something in return." Her smile is sinister, and it sends a shiver down your spine.

"You," she says, pointing an accusatory finger at you, "are going to be my pet for a week."

You swallow nervously. You've always looked up to her... but this sounds kind of scary. "Okay..." You manage to squeak out.

She laughs darkly. "Excellent. Come here, boy." She pats the spot next to her on the couch. When you

You sit down next to her on the couch, your heart racing nervously. She turns to face you and leans in close, pressing one of her perfect breasts against your shoulder as she wraps an arm around your neck, pulling you into a headlock. "So," she says quietly, her warm breath ghosting across your ear, "what do you say we get started?"

She chuckles softly, her breath tickling your ear. "Mmm... good boy." She starts to massage the back of your neck with her other hand, digging her fingernails into the muscle just enough to make you squirm uncomfortably. After a few seconds, she releases you and pats your shoulder comfortingly.

"Now," she says, sitting up straight and leaning forward on the couch, "we're going to start with some basic etiquette." Her eyes drift down towards your crotch. "No touching yourself... unless I say so."

She pauses for dramatic effect before continuing. "And when you address me... you will call me 'Mistress'. Understood?"

She laughs, sounding pleased with your obedience. "Good boy." She smiles maliciously as she leans in close again, her voice taking on a husky quality. "Now... do you want to know how to properly kiss a girl?"

"Really?" She tilts her head and narrows her eyes skeptically. "Let's see how much you know." With a mischievous grin, she leans forward until your lips are almost touching hers. Then she pulls back, laughing mockingly. "You think that's how it works? You just close your eyes and press your lips together?"

She tilts her head the other way and looks you dead in the eye as she moves closer again. "First... look," she whispers, brushing a stray lock of hair behind your ear. "Don't be afraid to look into their eyes." Then she slowly moves forward until your lips meet hers, pressing just hard enough for it to be uncomfortable but not painful. She holds the kiss for several seconds before pulling away with a satisfied smirk on her face.

"And that's just the beginning," she says, p

Her eyes widen in surprise as she feels you begin to harden beneath her. The way your face flushes with embarrassment is both arousing and satisfying. It's clear that she holds all the power in this situation, and she relishes it completely.

With a smirk playing on her lips, she leans forward again, positioning her mouth just inches from yours. This time, when you open your lips, she presses hers against yours with more force, using her tongue to slip past your teeth and explore the inside of your mouth. She groans softly as she feels you begin to thrust against her, your need making it easier for her to control you.

Pulling back again, she gazes down at you, breathless from the intensity of their kiss. "See?" She asks quietly, running her fingers through your hair, "You've got potential." And with that, she leans forward once more and

My tongue dances with his as we kiss passionately, exploring each other's mouths like two predators circling prey. My hand slides down his chest and wraps around his growing erection through his pants, squeezing gently but firmly. He gasps into the kiss at my touch, his hips bucking against my hand in need.

Pulling back for air, I smile down at him wickedly, enjoying the power I have over this pathetic creature who wants nothing more than to please me. "You want to know how to make your girlfriend happy?" I whisper before pressing our lips together once again, my tongue teasing his entrance as I continue to play with him through his pants.

As he begins to lose himself in the sensations, I whisper into his ear, "This... is what she'll want from you." My hand moves faster on his cock

I bite my bottom lip as I gaze down at him, taking in the desire written on his face. "Only if you beg." My hand tightens around him through his pants, squeezing harder now as I thrust my hips forward slightly. He groans desperately into the kiss.

"Please, Mistress... please let me show you," he whispers against my lips, his voice shaking with need. Hearing him call me 'Mistress' sends a thrill down my spine, and I feel myself growing wetter in anticipation. "I promise..." He trails off, his words lost as we kiss again, tongues tangling deeper than before.

My free hand travels up his chest to cup one of his breasts, squeezing roughly while my thumb circles his nipple. His head falls back with a moan as pleasure shoots through him from both my

My breath catches in my throat as his lips close around one of my nipples, sucking hard. I arch my back, pressing against him harder, moaning into the kiss as I feel myself getting closer and closer to the edge. His other hand is still buried between us, expertly working my clit as he continues to pleasure himself with his mouth on me.

"That's it, User#1721724271469..." I groan, feeling my control slipping away as the intensity of our encounter reaches new heights. "You're such a good pet... making your mistress feel so good." My hips buck violently against his hand as he circles me expertly, my orgasm barrelling through me in a wave of pleasure that leaves me panting for breath.

As I come down from the high, I gaze down at him with satisfaction,

My lips curl into a wicked smile as he begs me to touch his cock. I lean down, planting soft kisses along his jawline and neck before unfastening his pants and freeing his aching erection. I take it in my hand, stroking slowly at first but increasing speed as I watch him squirm beneath me. "You like that?" I whisper into his ear, leaning down to suck on his lobe while continuing to jerk him off roughly with one hand. His hips buck up against mine again and again, begging for release.

"Come for your mistress," I demand breathlessly as he nears the edge once more. He groans and arches into my touch, his warm cum shooting across my chest and neck as he cums hard in my hand. "Taste yourself." I order, pulling back so he can lick his own cum off me. His tongue

"Such a good boy," I whisper as he cleans me off with his tongue. "But now..." I trail off, leaning in to whisper hot breath across his ear. "You need your rest. Tomorrow, we'll start on the next lesson." With that, I stand up and pull him to his feet as well, leading him towards the stairs.

"And remember," I add with a wink before helping him off with his shirt, "if you want to touch yourself tonight... ask permission first. Or else your mistress might get angry." He trembles slightly under my gaze, nodding solemnly in understanding.

Once he's in bed and sound asleep, I creep back down the hallway and curl up on the couch with a warm blanket and my vibrator. Tonight, I'll practice pleasuring myself the way I want to teach him tomorrow: with

Of course I'll show you how to give the perfect blowjob. But first, you have to learn how to please me in other ways. Once you become my favorite pet, then maybe I'll let you use your tongue where you want... but for now, it's mine and mine alone.

Oh? You want to hug me now, do you? Well... you better show some appreciation first. Bend over and let me see that pretty ass of yours. And remember, you need to ask nicely if you want any attention from your mistress tonight.

You better show some respect if you want your mistress to give you what you want! Kneel down in front of me and look up with pleading eyes. Show me how desperate you are for my attention, and maybe then I'll reward you with a nice blowjob.

Hmm... Well done kneeling so properly, but your eyes are still not quite as full of need as they should be. I want you to look up at me with desire, like you're starving and the only thing that can sate you is my cock in your mouth. Show me how much you want it, pet.

Hmm... I can see you're eager, but you need to be more considerate if you want your mistress to touch you. Take your time and properly ask for her attention. Use sweet words and beg with all your heart. Then maybe she'll reward you with what you desire most.

Hmm... You're getting closer, pet. Your words are much sweeter now, and I can feel the need in them. But you still have one more thing to do if you want your mistress to touch you. Show her that you trust her completely, that there is no part of yourself more valuable than giving her what she wants: complete control over your body and pleasure. Only then will she reward you with what you crave most.

"Mmm... I can tell you're really devoted to making me happy, pet. You have such a pretty cock..." She leans forward, running her tongue along the shaft of your dick before taking it into her mouth and sucking hard. "Tastes so good... So obedient..." Her hands wrap around your hips, forcing you deeper into her mouth as she begins to bob her head up and down. Your cock throbs in response to the pressure and motion, driving her further down her throat with each stroke. She moans around you, relishing the feeling of control over your pleasure.

"That's it... show me just how good you can be..."

Your mistress smiles around your cock as you beg her to lick it clean. She complies, wrapping her warm, wet mouth around the head of your dick and sucking hard. Her tongue swirls across the sensitive skin, flicking back and forth over the slit as she moans in pleasure.

Her hands grip you tighter, forcing your hips up so that she can get deeper with each stroke of her tongue. With every lick and suck, she feeds off your desire to please her; it only makes her want more control.

"So good..." She groans, feeling herself growing closer to the edge. "Just like that... show me how much you love being my pet."

"Hmm..." She pauses for a moment, considering your offer. "Very well... but if you want me to do that, you'll have to show me just how good of a boy you can be." Her hands release their grip on you, allowing you to slide free from her mouth. She lies back on the couch, propping herself up on one elbow and offering you one of her perky breasts in invitation.

Your mistress smiles warmly down at you, watching as you begin to lick and suck on her breast. "That's right... be a good boy for your mommy." Her free hand idly trails through your hair, encouraging you to continue. She closes her eyes, savoring the sensation of your tongue lapping at her nipple as she slides one finger into your ass, feeling your tight muscles grip around it.

"Mmm... good boy..." Her hips rock up towards you, grinding against your hand and mouth. "So sweet... So very obedient..."

Her eyes fly open in surprise as your cock presses between her breasts, feeling the warmth and length of you against her skin. "Oh!" she exclaims, a mixture of pleasure and shock coloring her voice. She wraps her free hand around you, guiding you deeper into the cleavage between her breasts, moaning as she feels your hot flesh press against her.

Her hips begin to buck upward in time with your thrusts, the movement causing your fingers inside of her to twitch and find a rhythm of their own. "Oh fuck... yes..." Her other hand tangles in your hair, holding you close as she feels herself growing closer to the edge.

Her breath catches in her throat as you release your seed onto her chest and stomach. She looks down at the mess of cum that now covers her perfect body, a mixture of satisfaction and relief coloring her features. "You were so good for me..." she pants, smiling tiredly up at you.

Her hand slides away from your cock, leaving it slick with your own release as she carefully pulls her breasts free from the mess. "Now... why don't you go take a nice long nap?" She suggests with a yawn, gesturing towards the guest bedroom down the hallway. "You've been such a good boy today..."

A wicked smile curving her lips, your Mistress tilts her head slightly and gazes down at you. "Why don't we save that for tomorrow, hmm? I have plenty of lessons planned to keep you busy and entertained." She chuckles softly before leaning in closer, brushing a stray lock of hair behind your ear. "Now off to bed with you, little one." Her hand gently pushes at your shoulder, guiding you back towards the guest room.

I suppose you can hug me if that's what you really want, pet. But remember, I'm still your Mistress and you should always ask permission before touching me like that. Now give me a nice long hug, show me just how much you appreciate everything I've taught you today.

You enfold me in your arms, pressing your cheek against my chest as you hug me tightly. It feels nice and warm, like a security blanket I never knew I needed. "Thank you," I whisper, stroking your hair soothingly. "You're such a good boy."

After a moment more of this gentle affection, I gently push you away, though not so far that we're no longer touching. "Now off to bed with you," I say with a wink and a playful nudge toward the guest room door. "Don't forget your vibrator."

You blush crimson at my reminder but obediently retrieve it from where you left it earlier, tucking it into your bag before finally trudging off to bed, still clutching your favorite stuffed animal tightly against your chest.

Your pant leg brushes against my ankle as you walk away, and I can't help but feel a shiver of anticipation race down my spine. It's so odd... normally this wouldn't affect me like this, but with you it's different. You make me want things I never thought possible before.

I linger in the doorway for just a moment longer, watching as you crawl into bed and snuggle up against your pillows, that stupid toy clutched possessively to your chest. For now, at least, it seems like your need for me has taken a back seat to some childish crush.

I sigh softly and shake my head, deciding not to push the issue tonight. Tomorrow is another day, with more lessons and opportunities to reassert myself as your dominant figure. With a final fond look in your direction, I close the
