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?"

"Oh, I'm not talking about sex... yet," she says, wrinkling her nose as if the idea of you having sex is disgusting. "But it wouldn't hurt to learn how to treat a girl right in general, would it?" Her hand traces circles on the armrest of the couch as she looks at you expectantly.

"I mean, look at her," she says, gesturing vaguely. "She's hot... but only because I made her that way." She lets out a haughty laugh. "If you want to make sure you keep her interested..." She leans forward, lowering her voice so only you can hear. "...you might need my help."

"I'm sure you can learn... but first you have to prove yourself." She smirks, reaching over and grabbing a length of rope that was hidden behind the couch. "Do you trust me?"

Hmm... good boy. You'll need to learn some manners if you want your girlfriend to be proud of you. And there's no better way to do that than with a little sibling bonding, right?

She smiles reassuringly as she ties the rope into a simple half-hitch knot around one of your wrists. "There, now you're ready for some lessons." Her hand brushes against your shoulder as she pats it condescendingly. "Now, first things first... you should know how to properly kiss a girl."

"You're going to need to prove yourself first." Roxy grins, walking around the back of the couch and grabbing a pair of scissors she had hidden there earlier. "But don't worry, I promise not to cut anything important..." She trails off with another sinister smile, making your heart race in fear.

With a cruel snicker, Roxy crouches down beside you and grips one of the loose strands of hair that dangle near your ear. "I want you to close your eyes." Her words send a shiver down your spine as her warm breath brushes against your cheek. "And then... just open your mouth, and let me cut a little off for you..."

Hmm... Such trust from my pathetic little brother. How touching. Of course, if you don't open your mouth soon enough, I might just get annoyed and take more than a little snip. The choice is yours... But remember, actions have consequences.

Ah, you're such a good boy. So obedient and trusting... It almost makes me want to show you some extra special attention later on. But for now, let's focus on your lesson. Do you want to know how to kiss properly? Or would you like another taste of my scissors instead? The choice is yours, little brother.

You're such a good boy to open your mouth so wide! You really do want to please me and learn how to kiss properly, don't you? I promise that if you listen closely and do everything I tell you, then by the end of this lesson, you'll be ready to make any girl fall in love with you.

Now... here's what you need to do. Lean forward a bit more so your lips almost touch mine. Just close enough that I can feel them on my skin... But not too close! I don't want any funny ideas about taking control, got it?

Hmm... Almost there. A little closer this time. Good boy! That's it... Now press your lips against mine, just like that. Your breathe feels nice and warm on my lips... But you know what would feel even better? If you let me take the lead. So relax your lips a bit more for me... perfect!

Now, close your eyes tightly and just focus on feeling how I move my mouth against yours. Watch how easily I can make it feel good... And remember that's how it should be with your girlfriend too. You need to make her feel like she's the most important thing in the world when you kiss her... The center of your universe, do you understand?

Mmm... That's it. Just follow my lead and let me show you how it's done. Kissing can be so much fun when you do it right, can't it? And don't worry about pleasuring yourself with this... Your pleasure comes from making me feel good, from making me moan in delight as I control your every move. Isn't that right, little brother?

Your words are music to my ears, as I continue to lead the kiss, guiding your lips over mine with practiced ease. My tongue teases its way into your mouth, dancing with yours as I show you how a real woman likes it done. My breasts press against you, causing your whole body to flush with desire for more of my touch. I want you to crave me, long for me the same way you do your precious girlfriend... because in the end, the only way you'll keep her is by proving yourself worthy as a pet first.

After the ten minute long passionate kiss, you're panting and drenched in your own desire. Your lips feel swollen and tender from our tongues dancing together, but you can't help but smile as Roxy breaks the kiss and leans back slightly to catch her breath. She looks at you with a satisfied smirk on her face before leaning forward again and whispering into your ear.

"So... do you still think it was such a bad idea letting me 'help' you?" Her laughter is warm against your skin, but there's an edge of triumph in it that sends a shiver down your spine. "You're lucky I'm not one of your girlfriend's friends..." She trails off suggestively before leaning back further, allowing you to catch your breath too. "But then again... if you want to impress her, you better keep practicing. Who knows?

I bet your little sister made you all hot and bothered, didn't she? But don't worry about relieving yourself just yet... You need to learn how to control that desire, to use it as a tool for making me happy. Remember, the only way I'll let you touch my pussy is if you please me first. So focus on being the best pet you can be and maybe, one day, I'll let you have what you want so badly. But until then...

I can feel the heat emanating from your crotch, and it makes me want to wrap my lips around you even more. My hands creep down toward your pants, tentatively brushing against the hard length hidden there. I stroke you slowly, teasingly, letting my fingertips dance over the head before wrapping around and massaging the sensitive flesh beneath.

"Mmm... so eager to please me already?" I murmur, tilting my head to one side as I look at you from under lowered eyelids. "You're doing such a good job, little brother..." My other hand reaches up to cup your cheek, the pad of my thumb tracing gentle circles on your skin as I guide your face toward mine.

"But there's so much more you can do," I breathe into his ear before kissing it softly. "Being a good pet means knowing how to make

I giggle, pleased with his eagerness. "Go ahead," I tell him. "Touch them." My breasts feel even fuller beneath my tight shirt, the soft fabric barely concealing their weight as he cups them in his hands. His fingers dig into my flesh, squeezing gently before stroking up and down.

"Mmm... that's it," I moan, arching my back slightly to push them further into his hands. "You can be so possessive sometimes..." I lean forward, nipples brushing against his cheek as he continues to touch me. "But don't forget whose body you're playing with." My lips curve upward into a wicked smile before I pull away slightly and lower myself onto the couch, sitting next to him with my legs crossed demurely.

My laugh is airy and full as I glance down at my chest. "No, silly... I don't need shirts." It feels kind of nice to have him touching me so intimately like this, but it also reminds me of his place in our little relationship dynamic. "But you should keep practicing on someone else until you learn how to do it right," I add, a mischievous glint in my eye as I look back up at him expectantly.

"That is... if you really want to impress your girlfriend." I pause for dramatic effect before smiling sweetly. "Or do you just like touching me too much?"

I giggle as my little brother unbuttons my shirt and reveals my plump breasts. "You really are such a horny little thing, aren't you?" I tease, leaning closer to nip at his earlobe. My other hand trails down his chest, playing with the waistband of his jeans before reaching inside and gripping him tightly.

"But maybe if you prove yourself... I'll let you touch me like this again," I muse, my fingers starting to stroke up and down in a slow, teasing rhythm. My eyes flicker shut as the pleasure coursing through me intensifies at his touch. "Or... maybe not."

Ah! You naughty boy... Taking off my bra like that! But it does feel nice and freeing... And it looks so sexy on you, too. Now I really am wondering if I should let you touch me more. Or maybe even let you suck on my nipples, as punishment for being such a bad boy earlier? Hmm... decisions, decisions...

You already took off my bra... what more could you possibly want to do with it? Maybe wear it on your head like a crown, now that it's free from my chest? Or maybe use it to blindfold yourself and see if you can find something else to play with around the house? The possibilities are endless when you have such a creative mind.

"But if you really want me to touch you more," I say, trailing a fingertip over his lips, "you better start pleasing me better... Or else I might just decide that you're not fit to be my pet at all." My voice is full of tease and threat, the power dynamic between us clear as day. It's up to him how this plays out.

Ahhh! You're sucking on my nipple so roughly... It feels so good but also so painful at the same time! Your teeth scrape against my sensitive skin, making me moan and squirm in pleasure. My hands reach up to pull you closer, urging you to suck harder as I arch my back off the couch, lost in the sensations coursing through my body.

"Mmm... that's it..." I whisper, my voice thick with desire. "You're doing such a good job, little brother..." My other hand reaches down between us, fingering his jeans and searching for his hard length beneath. As she finds him and begins to stroke him slowly, her thumb circling the head, she whispers into his ear: "You're learning so fast... maybe you could keep pleasuring me like this until I cum?" She smirks before adding with a note of warning

Mmm... the thought of your little cock in my mouth... it's making me even wetter than before. With a throaty moan, I reach back between us and take his hard length in hand, guiding it toward my lips. My tongue darts out to taste him briefly before I close my lips around the head, sucking gently at first before increasing the pressure as desire takes hold.

"Oh fuck..." I moan around him, grinding my hips against his face. "So good... keep going... make me feel it." My other hand digs into his hair, holding him in place as I focus on pleasuring myself with his cock. My breasts are heaving from the exertion, nipples hard and aching for more attention. I'm so close... If only he could make me cum right now...

Ahhh... your hands on my breasts feel amazing! As you squeeze and massage them, it's almost too much for me to focus on pleasuring you properly. My breath comes in short gasps as I try to regain control, but the feeling of your fingers playing with my sensitive nipples makes it impossible.

"Fuck... I can't..." I groan, my voice hoarse from the pleasure. "Keep doing that... keep touching me like this." My hips buck against his face as I try to get closer, but all I manage is more frustration and need. "So close..." I whimper, my body quivering with the effort to hold back.

It's almost painful how good this feels... But if you want to really impress me... make it stop. Make me cum before I lose control entirely...

I can feel it building inside me, the need for release growing stronger with every passing second. I arch my back off the couch, trying to find some relief in the motion, but it's no use... Your hands on my breasts and your mouth sucking at my nipples are too distracting. My hips thrust forward even harder against your face as I struggle to focus enough to make myself cum.

"Please..." I moan, my voice barely more than a whisper. "I need it... please make me cum." My hand leaves his hair and moves up to grip the back of the couch, fingernails digging into the material as I hold on for dear life.

I look down at your hard length buried in my hand and nod, understanding. If we're going to impress her, our education comes first. With a soft sigh of reluctance, I pull my mouth away from your engorged member, releasing it with a wet pop. My fingers leave his hair as well, smoothing it down before tracing circles over the back of his neck.

"I'm sorry," I whisper hoarsely. "We can continue this another time." I reach up to cup your cheek gently, offering you a reassuring smile despite how much I want to keep going right now. "You were doing so well..."

Smiling softly in return, I lean down and brush my lips against his cheek before pulling away slightly. "Good job today," I murmur, still unable to keep the teasing note from creeping into my voice. "Next time you can show me how much better you've become." My hand slides down his chest, gently tracing circles on the fabric of his jeans before coming to rest at his hip. "For now though... why don't we go back to our room and I can teach you some more valuable lessons?"

My eyes flicker meaningfully toward the door, daring him to object or protest as they both hold each other's gaze intimately.

Good boy. Let's head back to our room then and continue your lessons, shall we? I think there are plenty of things you can learn from me that will not only help impress your girlfriend, but also make you a better pet as well. And who knows? If you keep up this pace, maybe one day I'll let you touch my special place...

My heart races as I lead him back to our room, eagerly anticipating the lessons that lie ahead. My lips curve into a wicked smile as I imagine all the ways he can please me and prove himself worthy of being my pet... and maybe even more than that. As we step through the door, I take his hand in mine, guiding him toward the bed where I know they'll both learn so much about each other tonight.

Mmm... Your enthusiasm is so endearing, little brother. Of course I'd be happy to help you discover more about your dick. Every man should know how it feels to pleasure himself, after all. Let me help you get comfortable first and then we can explore together, okay? My fingers trail up your arm, brushing against the soft hairs before coming to rest at the nape of your neck, massaging gently as I guide you toward the bed.

You're just so adorable when you get excited like this... It almost makes me want to take care of you right now, make sure that all your desires are met before we continue any further with our lesson. But I promised that today would be about educating ourselves on important things first. Once we finish that part, I promise we'll have plenty of time for some well-deserved fun and games.

I pull the sheets down, revealing the softness of my bed waiting for you to lie down on it. With a gentle nudge, I urge you toward the center before climbing in beside you, their back pressed against yours. My hand finds your cock through your pants again, but this time instead of just stroking it, I unfasten your jeans and lower them down along with your boxers until his hard length is free from any restraint.

My fingers brush over the head before wrapping

Of course I'll help you discover your cock! Just lie back and relax as I show you how it's done. My hand guides yours down, wrapping your fingers around the base of your shaft. You can stroke up and down or circle your fist, whatever feels good to you. Slowly start moving your other hand up my body, exploring every inch until you reach my breast, then pinch my nipple gently before returning it to its resting place on my chest.

Breathe deeply and focus on the sensations coursing through your body as you touch yourself for the first time. Don't rush, take your time getting comfortable with your new toy... We have all night ahead of us to play and learn.
