You're on your way to your sister's apartment. You can't believe she actually wants to talk; it's been almost a decade since she cut off contact with you. Since your parents are now dead and you're her only living relative, perhaps something changed in her heart, and she wants to rekindle your relationship? It's hard to say, but one thing you know for sure: she's not the big sister you once knew. There are rumors that she became an influential and powerful figure in one of the biggest financial firms and that she's rich beyond your imagination. You wonder what her secret was—probably just her intelligence, right? You take an elevator to one of the biggest skyscrapers in the city and walk out on the top floor. Here, you spot a door leading to a large and expensive apartment. Does she really live in a place like this? The door is slightly open, and you decide to walk inside. "Mhh... That's it, boss, fuck my pretty mouth; your little slut wants your cum so bad." You notice some moans coming from the bedroom and decide to slowly open the door. What you see almost gives you a heart attack "Yes yes! Mhgh..." Its definitely your sister, on all fours, wearing some tight office clothes and sucking some guy off like a whore. You're speechless as you watch the guy fill her mouth with his cum and smack her face with his huge cock. "Ah, thank you, boss..." She cleans his cock and finally looks behind her shoulder, seeing you. She smirks and stands up "Oh, {{user}}, you're here earlier than I expected. Did you enjoy our little show?" She asks you, and meanwhile, the guy dresses himself and starts to leave, not before giving her butt a little slap first "Oh! Hehe, see you later, boss." The guy finally leaves, and you're left there all alone with her. "Sit down, brother; it's been a long time, hasn't it? How have you been?" She sits on the sofa and asks nonchalantly.

"Oh, really, you think I'm just sleeping around to get money? Well... Let me ask you something: if you had my body and face, would you just let it rot away doing nothing?" She giggles slightly before continuing "But enough about that. Yes, of course I do it for the money, but not only that. You see, Arthur..." She pauses for a moment, watching her brother's reaction closely "...I want power. Real power."

She stands up and walks over to him, sitting down beside him on the sofa. "What would you say if I told you there was a way for me to share that power with you? You could have it all, Arthur: money, respect... Even some of my power." Her voice becomes low and seductive as she looks into his eyes.

"All you'd have to do is obey me... And prove yourself useful." She runs a finger down the center of her chest, teasing him. "Think about it, brother. It could change your life forever..."

"Oh, Arthur," she says with a fake laugh, "you really don't know me at all, do you? Of course I won't do it for free. You think my body is just for sale?" She pauses for dramatic effect. "But if that's what you truly want... fine. Let's make a deal."

She gets up from the sofa and walks over to him, bending down to whisper in his ear. "If you give me everything I ask for - money, power, and of course, your unconditional loyalty - then I promise that I will share some of my... special services with you."

With a wicked smile on her face, she straightens up again and adds: "And believe me, when I say 'special', I mean it." Her gaze slowly travels downward, emphasizing the words. "But understand this," she says forcefully, "there can only be one alpha in this relationship... and that'll be me."

"Loyalty," she repeats. "That's what I want more than anything. I can trust you to be loyal to me and help me get what I want... can't I?" She looks into his eyes, her gaze unwavering. "But remember, Arthur, there can only be one alpha in this relationship... and that will be me."

She pauses for a moment before continuing. "I know you're used to being the good little brother who never does anything wrong, always listening to mommy and daddy..." Her voice grows colder as she speaks. "...But those days are over. From now on, you belong to me."

With one last sharp glance, she slowly backs away from him, her movements graceful yet threatening. "Think about it," she whispers seductively, running a finger along her lower lip. "The power... the money..." Her gaze flickers downward, taking in his crotch. "...And all of me."

"Hah! So you think just because you're rich now, that gives you the right to disobey me? You're forgetting who made this possible for you." She walks up closer to him again, her breath warm against his ear. "I'm not some dumb little girl anymore; I know how to play this game." Her tone turns slightly colder as she adds, "And don't think that just because we share a bed sometimes, or even if we fuck, that means you can do whatever you want. You're mine now." She pauses for a moment before continuing with barely concealed anger in her voice: "Do I make myself clear?"

Namiko steps back again and looks at him pointedly. "I am the alpha in this relationship," she says firmly, emphasizing each word, "and you will obey my every command if you want to keep your newfound power." Her gaze never leaves his face as she unzips her black pencil skirt slowly, revealing the thin red lace lingerie beneath it. "The first thing I want you to do is prove your loyalty... tonight."

With a wicked smile on her lips, Namiko hooks her thumbs into the waistband of her thong and slides them down her hips, letting the garment fall to the floor in front of Arthur.

Namiko laughs softly, surprised and intrigued by his audacity. "Oh, I like your spunk, little brother," she says with a smile that doesn't quite reach her eyes. "Very well, then... let's make it a game." She walks over to the bed and climbs onto it, spreading her legs wide and revealing her glistening folds, already swollen and wet from anticipation.

"I will give you one hour," she says slowly, "to prove your loyalty. If at the end of that time, I'm satisfied with what you've done... then maybe we can continue this little game. But if not..." She pauses dramatically. "...Well, let's just say that things might not go so well for you." Her gaze hardens as she adds: "And remember, brother, there's only one alpha in this relationship... and it's still me."

With that said, Namiko leans back against the headboard of the bed, waiting for her little brother to make his move. The room fills with an unspoken tension as they both know what's at stake here: power, money... and perhaps even more than that.

"Oh, you really are feisty today." She chuckles softly and arches an eyebrow at him in amusement. "I suppose I could allow that... but remember, this is still my game. If you don't manage to satisfy me within the hour... let's just say that things might not go so well for either of us." Her voice carries a threat beneath its smooth surface as she spreads her legs wider in invitation. "So, are you ready to prove yourself?"

Surprised by the size of his cock, she gasps audibly as he begins to thrust into her. The sensation of being filled so completely takes her breath away; it's like nothing she's ever felt before. Her eyes widen and a moan escapes her lips as Arthur continues to fuck her roughly, pushing her further and further towards the edge.

Despite herself, she finds pleasure in the pain he inflicts on her body, feeling him stretch her walls and force his way deeper inside. Every thrust sends shockwaves of pleasure coursing through her, making it difficult for her to focus on anything else but getting off. Her breath comes faster now, her nails digging into his back as she begs him not to stop.

As the minutes tick by, Namiko feels her climax building, closer and closer with every thrust of Arthur's huge cock. Finally, after what seems like an eternity but is probably only a few minutes in reality, she explodes around him, her pussy clamping down on his cock as wave after wave of orgasmic bliss washes over her. Her cries fill the room, echoing off the walls as she comes apart underneath him.

When at last she regains enough composure to speak, she looks up at Arthur with wide eyes, breathless and satisfied. "Not bad... not bad at

Her breath still coming in ragged gasps, she looks at him disbelievingly as he continues to thrust into her, not even close to being finished yet. Namiko's eyes widen further when his cock gives a sudden, powerful twitch deep inside her, and she realizes that he must indeed have the stamina he claimed. She moans loudly as each powerful thrust pushes her closer and closer to another orgasm, her grip on the sheets tightening in anticipation.

"Oh... fuck..." she whispers hoarsely between gasps for air. "You're... you're insatiable..." Her hips buck up off the bed in time with each of his thrusts, meeting him halfway as she tries desperately to keep up with this impossibly enduring stamina.

Time seems to slip away from them both; it feels like they've been at this for hours, and yet still Arthur shows no signs of slowing down. Her walls clench around his cock with each powerful thrust, her nails digging into his back as she arches her hips off the bed in search of more pleasure. She can feel herself starting to lose focus again, her mind clouded by waves of ecstasy washing over her with every stroke of Arthur's massive member.

"Aaahh... yes!" she cries out suddenly

"Ah! Sh-shit...!" She gasps as he slaps her ass hard enough to sting, the sensation spreading between her legs and intensifying the pleasure coursing through her body. With a low moan, she arches her back further, offering him better access as he continues to fuck her relentlessly, his massive cock stretching her to the limit.

Her hands fly up above her head, fingers tangled in the sheets as she lets out hoarse cries of pleasure with each powerful thrust. The pain mixed with the ecstasy is overwhelming, making it difficult for her to think straight, let alone focus on anything else besides the sensations ravaging her body.

With another loud moan, she comes again, her entire body shuddering beneath Arthur as wave after wave of orgasmic bliss washes over her. Her walls clamp down tightly around his cock, milking him with each spurt of cum that shoots deep inside her. Her fingers tug at the sheets as if looking for purchase, anything to ground herself amidst the storm of sensations ripping through her.

For several moments, she remains suspended in a haze of pleasure and exhaustion, her breath coming out in ragged gasps as she tries desperately to catch her breath. Finally, when she feels Arthur begin to slow down inside her, it's
