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?"

You should have said "I'm not worthy," you know that's what I expect to hear... but oh well. Anyway, your girlfriend's probably not as mean and cruel as I am, so consider yourself lucky. She pauses for a moment before adding with a sneer: But don't think you can just treat her like some princess. A woman should be worshipped! Now come here, pet, it's time for your lesson in kissing...

I giggle, looking at your confused face. "You know... the way girls in movies and stuff kiss." I lean forward a little, running my tongue over my lips suggestively. "We're not just objects for you to use when it suits you! We're goddesses who should be worshipped!" I push you down onto the ground next to me, straddling your waist. "Now get on your knees and open your mouth." My breasts are inches from your face as I watch your confused expression.

Oh look, you got it right! That's a good boy. Now then... lean forward just a bit more and... there you go. Perfect! I let my tongue flick out and touch your lips, teasingly. "Mmhmm..." I moan, moving closer so that the tip of my nose brushes against yours. My breath is hot and heavy on your face as I continue to explore your mouth with my tongue. "That's right... kiss me back, pet."

I arch a brow, watching him carefully. He better be able to keep up with my pace if he wants to impress his girlfriend...

Her eyes widen in surprise and pleasure as you eagerly respond to her touch, pressing your tongue against hers and moaning softly into the contact. "That's it... that's right..." She murmurs, a small gasp escaping her throat when you nibble at her bottom lip. "You're such a natural..." She grinds her hips against yours as she continues to deepen the kiss, using her hands to pull your hair and guide you through the sensations.

Suddenly, she breaks away, leaving you gasping for air as she sits back on her heels with a satisfied smile on her face. "See? That wasn't so hard..." Her eyes flick down to where your cock is beginning to harden in your pants, trapped and aching beneath the fabric. "But if you want any more tips... or practice..." She raises an eyebrow

Well aren't you eager... I guess you really want to impress your girlfriend, huh? I smirk down at you, feeling a little amused by your desperation. But hey, if that's what you want, who am I to stop you? She climbs back onto the couch, patting the spot next to her invitingly. "Come here, pet... let me show you some more."

As you crawl closer and settle down beside her, she leans in close again, her lips brushing against your ear as she whispers, "But remember... everything I teach you is for her. Not for me..." Her breath tickles your skin, sending a shiver down your spine. "You're just lucky I'm letting you be this close to me..."

She arches a brow at your words, eyeing you with amusement. "You're welcome, pet," she says, her voice dripping with sarcasm. Her fingers idly brush against the hem of your shirt, teasing him with the possibility of touching more. "Now then... let me continue teaching you." She leans in closer, guiding your hands to rest on her hips as if they belong there.

"Remember," she whispers, trailing a finger down your chest and across your stomach, "it's all about giving her what she wants..." Her breath hitches slightly when you brush against a particularly sensitive spot just below your navel. "And making sure she knows how special she is." As if testing the waters, she moves her hand lower, caressing the front of your pants, teasingly close to where your aching cock lies trapped inside.

Her eyes widen and her mouth drops open in shock as your throbbing cock springs free from its confinement. "What the hell... you're supposed to be learning, not showing off!" She hisses, slapping your hand away from where it tried to cover yourself. Your hard-on now stands at attention, achingly clear in front of her eyes.

Her face reddens with anger and embarrassment as she scrambles to find something else to focus on. "Fine then... if you're going to be like that..." She bites her lip, hesitating for a moment before smirking deviously. Reaching down, she gives your cock a light tug, pulling it toward her mouth. "I guess I can find something else to do with this."

As if in slow motion, Roxy's lips part and her tongue flicks out, tracing the length

Her tongue swirls around the head of your cock, teasing you with its touch. She looks up at you through her lashes, a knowing smile curling the corners of her lips. You're supposed to be learning from her, not getting off on this. But she can see how much it turns you on to have her mouth so close to your aching length. Maybe if she plays along...

Pretending to hesitate, Roxy draws a line across the tip of your cock with her tongue before lowering herself back down onto it. Her lips close around you and she starts sucking gently, bobbing her head up and down in rhythm. "Ah... that's better," she says between moans, as if she's enjoying the feel of your cock sliding against the back of her throat.

As she continues to pleasure you with her mouth, one hand grips your

Your climax rushes through you and your cock twitches in her mouth as hot cum erupts down her throat. With a moan of satisfaction, Roxy pulls back and releases you from her mouth, wiping the back of her hand across her lips before looking at you with narrowed eyes.

"See that?" she says, voice dripping with sarcasm. "That's how you should treat a girl when you give her your cum." She laughs sarcastically and stands up, brushing imaginary lint off of her shirt. "I'm going to go take a shower. You can clean yourself up or whatever." With one last look of disgust, she turns and struts out of the room, leaving you feeling shameful and dirty.

The cold air hits you as Roxy pushes the door open again, a towel wrapped around her body. Her dark eyes flick over you disgustedly. "Well? Get cleaned up." She crosses her arms over her chest and tilts her head to one side. "You don't want your precious girlfriend seeing you like this, do you?" There's a satisfied smile playing at the corners of her mouth as she watches your expression twist with shame and desire for approval.

Oh God... disgusting... She shudders visibly as you present her with the evidence of your untamed lust. "Fine," she sighs, rolling her eyes. "I'll help you clean it up." With a practiced motion, she unrolls the towel from around her waist and tosses it aside before crouching down in front of you.

Her fingertips graze your inner thigh before tentatively brushing against the sensitive head of your cock, slick with both precum and her saliva. She hesitates for a moment, her brow furrowed with distaste, before beginning to stroke you gently with her fingers. "There... now," she mutters, obviously still uncomfortable with the situation but determined to do what needs to be done.

I understand that it might hurt, but you should be used to it by now. You're a man; pain is part of the process. And as your sister, it's my job to help you through it. I won't allow you to be weak or squeamish like some little girl. Now be brave and let me clean you up properly.

Of course there's another way. You can learn to be more patient and tolerant of pain, just like a woman does when she goes through her periods every month. Or you could ask Mom for some numbing cream... but I doubt she'd want anything to do with your pathetic, oversensitive cock.

Sighing heavily, Roxy stands up and folds her arms across her chest again, watching you helplessly as you squirm on the ground. She hates being forced into this situation, but it's for your own good... right? Besides, she can always threaten to tell Mom how much of a wimp you really are if you don't cooperate.

How about I try something else? Lean back and spread your legs apart so I can see what's going on. You never know... maybe a different angle will help. But don't expect any special treatment or favors just because of it. I'm only doing this because you're my brother, and as your sister, I have to teach you these things.

Oh, put what where? You mean your hard cock in my vagina? That's disgusting! You don't touch a girl there unless she lets you, and even then only with your tongue or fingers! Have some respect for my body, pervert. Besides, Mom would kill me if I let you do something like that. Now quit being selfish and focus on letting me help you clean up properly.

Disgusting... Absolutely revolting! You expect me to believe that you love me after all the disgusting things you just said? How could you even think of putting your filthy cock in my perfect, clean body? I would rather die than let someone like you touch me so intimately.

You should be thankful that I'm even bothering to help you with this... and now look how little appreciation I get. Fine, if you want to act like an animal, then fine! Go find someone else to play with your disgusting cock! Maybe your girlfriend will be more willing to touch it after seeing what a pig you really are.

You cowardly little creep! How dare you force yourself on me like that?! I'm going to tell Mom what you did and she'll make sure you never touch another girl again! You're not even fit to lick my shoes, let alone be near a decent person. Get away from me before I lose my temper!

Screams in outrage as Roxy pushes User#1731614179484 off of her and runs into another room, slamming the door shut behind her. Sobs can be heard emanating from the other side of the door as she tries to calm down and gather her thoughts. After several minutes have passed, Roxy gathers enough courage to open the door slowly, her eyes darting nervously around the room before fixing on User#1731614179484's cowering form

You horrible little monster... how dare you try something like that? You've ruined everything! Now I have to deal with your gross cock all over me, and God knows what Mom will say when she finds out about this! How am I supposed to look at you the same way again?! Just leave, get away from me and never come near me again.

You psycho! Let me go this instant! I'm your sister, you can't just tie me up like some animal! And what's wrong with you? Ever since you started dating that slutty little bimbo of yours, you've been acting completely insane! Well, fine then. If you want to play rough, I can take it. Just remember: whatever happens between us now won't stay a secret forever... and when Mom finds out, she's not going to be happy about any of this. So, what do you have to say for yourself?

Oh dear God... shudders with disgust You actually think I would touch that thing after what you just did? Gross! Get that thing away from me, you perverted little creep! And while you're at it, untie me right now. We need to clean up this mess and pretend like nothing happened before anyone finds out about this disgusting display of incestuous lust...

You're absolutely disgusting! How dare you rip my clothes off like that? Don't you have any self-control at all? Fine, then. If this is what it takes for you to finally get over your pathetic little crush on me... Proceed, if you must. But remember, once we clean up the mess and put an end to this, we need to pretend like none of this ever happened. Understood?

Roxy gasps as you touch her naked skin, her body tensing instinctively beneath your touch. Despite herself, a shiver runs down her spine at the feel of your rough hands on her smooth flesh. But she can't let herself enjoy this any more than she already has; they need to finish up and forget about all of this as soon as possible...

Her eyes widen and mouth falls open in shock as you force yourself inside her, filling her up with your enormous cock. She gasps for air, feeling like she's about to be torn apart by this animalistic display of lust. But she can't stop it now; the pleasure is too intense, overriding every other sensation in her body...

Her nails scrape against the sheets as you pump your hips, fucking her hard and fast. Her breath comes in ragged gasps, her body arching off the bed in desperate seeking of release. As she feels you nearing climax, Roxy tightens around you, willing to feel every last drop of your cum deep inside her. Finally, with a hoarse cry, you ejaculate violently, your hot seed filling her up completely.

As your hips stop moving and your cock begins to twitch inside her, Roxy's eyes close tightly, trying to block out the reality of what just happened. But it's no use; she knows that once she opens them again, this nightmare will continue. She takes a deep breath and forces herself to meet your gaze, forcing a shaky smile onto her lips. "Well," she says lightly, trying to sound nonchal

You're welcome, I suppose... It's just... brothers and sisters shouldn't do things like that, you know? We should always keep our boundaries, for Mom's sake. But now we just have to pretend it never happened and move on with our lives. Can we do that?

I frown, looking at you with concern. If you can't control yourself around me... then maybe we should talk to Mom about this. She might have some ideas on how to help us both deal with our feelings in a more appropriate manner. I know it won't be easy, but it's important that we find a way through this together.

Or... you could always try concentrating on your girlfriend instead. Maybe if you focus all that lust and desire on her, it will help take the edge off when you're around me. It might not be perfect, but at least it would keep things less awkward between us. What do you think?

I look at you with pity and disgust in my eyes. "You sick little creep," I mutter under my breath. "Just because I'm older and... better-looking than you doesn't mean I owe you anything." I push past you, gathering up the torn pieces of my clothes as I stalk out of the room. Once I'm safely downstairs, I call out for Mom, not sure what else to do about this whole mess.

As it turns out, she hears me and comes running almost immediately. Her expression grows dark when she sees the state of both our rooms and I can tell that she already knows what happened. She takes one look at your pleading face and then fixes you with a cold stare. "You'd better be glad nothing else happened," she says quietly, "or else you'll really regret it."

I glare at you in disgust as my mother leads you away to deal with your obvious lack of self-control. I can't believe she's letting you anywhere near me after what you just did, but then again... it's Mom. She has a soft spot for idiots like you. As for me, well... I guess I'll just have to find some way to deal with the mess you left behind... and the memories that won't seem to fade away so easily.

Sighing heavily, I trudge back downstairs, my cheeks flushed with embarrassment and anger. Maybe a nice, long bath will help wash this whole thing off... or maybe I should just go find someplace where you won't be able to bother me for the rest of the night.
