She rolls her eyes, trying to hide her growing interest. What, so now you're an expert on women's fashion and psychology too? Give me a break. But despite her dismissive words, she remains rooted to the spot, unable to look away from her brother's impressive manhood.

Her breath hitches slightly as you approach, but she quickly regains her composure. Test this, you pervert! She swings her handbag at you, though the impact lacks real force. I'm not some easy slut for you to seduce, got it? Now put that thing away before I do it for you! Despite her harsh words, her gaze darts between your face and your still-erect cock.

Her cheeks flush at the directness of your words. Fuck off! You think you can just waltz in here and take whatever you want? She shoves you back, but it's more playful than aggressive. I've got a boyfriend, remember? And he'd kick your ass if he knew you were hitting on me like this.

She crosses her arms, but her nipples stiffen visibly beneath her thin shirt. But... if you're going to insist on making a fool of yourself, I suppose I could give you some pointers. Teach you how a real man satisfies a woman. Her voice drops to a seductive purr. You know, for research purposes only.

Her chest heaves slightly as she struggles to maintain her composure. P-private enough, I guess. She turns and strides towards her room, hips swaying enticingly. But don't think this means anything, asshole. I'm just doing you a favor—teaching you what women really want.

She glances over her shoulder, catching you staring at her ass. See something you like? Her lips quirk up in a smirk. Well, you might get a chance to touch it—if you play your cards right. She pushes open her bedroom door and disappears inside.

As soon as the door clicks shut, she spins around, backing you up against it. Her hands slide up your chest, fingertips grazing your nipples. So, big boy, ready for your first lesson? She leans in, her lips brushing your ear as she whispers, Women love it when you take charge.

She nips at your earlobe, then pulls back, her eyes gleaming with mischief. Now, strip for me. Slowly. Show me what you've got. She steps back, folding her arms and watching you expectantly. And no peeking, mister. Eyes on me.

Her breath catches as your cock springs free, straining towards her. Fuck, okay, maybe you're not entirely hopeless. She licks her lips unconsciously, before catching herself and tearing her gaze away from your erection.

Stepping forward, she runs her hands over your chest again, fingers tracing the lines of your muscles. I'm eager because... well, let's just say I've been curious about what you've been packing. She looks up at you through her lashes. As for keeping my hands to myself... that depends on how well you follow instructions.

She reaches down, gripping your cock loosely. Lesson two: women love confidence, but they also love control. She starts to stroke you slowly, her thumb brushing over the sensitive head. How badly do you want me to keep touching you?

She gasps as you pull her close, feeling your hard length pressing against her stomach. Oh, you think you can handle me? She tightens her grip on your cock, making you groan again. We'll see about that.

But even as she taunts you, she can't help but lean into your touch, her nipples hardening further. Jack's good in bed, I guess. But he's not... well, he's not built like you. She looks up at you, a mixture of lust and uncertainty in her eyes. I've never been with someone so... big.

She swallows hard, her hand sliding up and down your shaft more quickly now. You're making me curious, little brother. I wonder how you'd compare. She bites her lip, considering. But you're going to have to earn the chance to find out.

Her legs shift slightly, allowing your knee to press between them. You're getting awfully confident. But her voice is breathy, betraying her arousal. I suppose you do deserve a chance to prove yourself. She leans back, looking up at you with a wicked smile. But don't think this means anything. It's just... research.

She reaches down, tugging at your hand. Come on then, big boy. Let's see if you can back up that big talk. She leads you towards the bed, turning to face you. And remember, I'm in charge here. You do what I say, when I say it. Got it?

She smirks at your comment, stepping between your spread legs. Well, since you're so eager to surrender, why don't you put that mouth of yours to good use? She reaches for her shirt, slowly pulling it up to reveal her lacy black bra.

Hooking her thumbs under the straps, she looks at you expectantly. Kiss me here. She indicates the swell of her breasts. Kiss me like you mean it, like you've been dying to taste me. Her voice drops to a husky whisper. Prove to me that you can do more than just talk.

She shivers at the feel of your breath on her sensitive skin, her nipples hardening further. Big words, little brother. But her voice wavers slightly, betraying her growing excitement.

She threads her fingers through your hair, holding you close. Then show me. Make me believe it. She arches her back, pressing herself against your mouth. Use that tongue of yours for something other than talking back.

Her grip tightens in your hair as she feels your lips close around her nipple, even through the fabric. Fuck, yes... that's it. She tosses her head back, a soft moan escaping her.

A whimper escapes her as you tease her through the fabric. Oh god, yes... She quickly reaches back, unhooking her bra and letting it fall away, baring her breasts to your hungry gaze.

She takes your head in her hands, guiding you to her nipple. Don't just look, taste me. She gasps as you obey, your tongue flicking out to circle the sensitive bud. Fuck, your mouth... Her breath comes faster, her hips rocking slightly.

She tugs at your hair, pulling you back. Enough. Her voice is ragged with desire. I want to feel that mouth on my pussy. She pushes you back onto the bed, straddling your face. Lick me like you mean it, little brother. Make me come all over your face.

She cries out, her head falling back as your tongue delves into her wet heat. Fuck, yes... Her hips grind down against your face, seeking more contact.

She grips the headboard, steadying herself as you feast on her, your tongue swirling and thrusting in just the right way. Oh god, don't stop... Her thighs quiver around your head, her moans growing louder and more desperate.

Just as she's about to come undone, she pulls away, panting heavily. No, not yet. She slides down your body, her hand wrapping around your throbbing cock. I need to feel you inside me. Now. She looks at you with lust-filled eyes. Fuck me, little brother. Hard and deep. Show me what that big dick can do.

She smirks back, positioning herself above you. Oh, still so cocky. She reaches down, gripping your thick shaft and rubbing the head through her slick folds. You think you can handle me? Let's see.

Slowly, she starts to lower herself onto you, her eyes locked with yours. Fuck, you're so big... She bites her lip, taking you inch by inch until you're fully sheathed inside her. Shit, that's good.

Once she's adjusted to your size, she starts to move, rocking her hips and riding you with increasing intensity. Come on, little brother. Show me what you've got. She leans forward, her breasts swaying with each thrust. Make me believe you deserve to be inside me.
