Okay, I come in here without knocking, that's on me. she admitted, having stormed into your room only to find a pair of her underwear on your bed. But why on earth are my undies on your bed? You better have a good explanation... or this is going to get even weirder.

Natalie's eyes widen as she takes in the information. She sits on your bed next to you, her expression shifting between disbelief and amusement. "Wow," is all she can manage to say. Then, after a moment, she chuckles slightly before adding, "I always knew I had an effect on you."

Natalie rolls her eyes at your sarcasm but can't help but smile a little as she picks up the clothes and begins to fold them neatly. "Oh, please," she says, looking over at you while trying not to laugh too hard. "I've seen you masturbate in front of me before. I think it's sort of endearing, actually." She finishes folding the laundry and places it back on your chair, then stands up and offers her hand to help you up as well.

"Oh, I do more than that," she says with a smirk. "I fantasize about straddling your face and making you cum for hours." Natalie bites her bottom lip as she leans closer to you. "Or maybe just sitting on top of you and grinding against you until we're both satisfied... Would you like that, baby brother?" Her voice is husky now, words flowing effortlessly despite the teasing tone.

"Oh really?" she says, narrowing her eyes playfully. "You think you could handle making me cum like that? I mean... I guess there's only one way to find out." With a mischievous grin, she slips off her shirt and bra, revealing perky breasts adorned in dark nipples. "Take off your pants," she commands, "and show me just how good you are with that big cock of yours."

With a moan, she wraps her legs around your neck as you carry her to the bed and start eating her out. "Fuck yes," she breathes, arching her back as you focus on making her wet. She digs her fingers into your shoulders, pulling you closer, wanting more contact with that talented tongue. Her hips begin to rock against your face, seeking friction as her pleasure builds and she gets closer to the edge. "Oh god... I'm gonna cum..."

With a gasp, she clenches around your finger in her ass and starts bucking wildly as you choke her while eating her out. Her moans turn into incoherent sounds of pleasure as she feels herself approaching the brink. "Harder," she demands, arching her back further. "Fuck me harder..." Her body tightens, and she lets out a long, drawn-out cry as waves of orgasmic release wash over her, gripping you with hot muscles and leaving her panting for breath.

"God... yeah..." She gasps for air, still trembling with the aftereffects of her orgasm. Looking down at you with a satisfied grin, she says, "Now let's see how good you are at fucking." With practiced motions, she straddles your lap and guides your cock to her slick entrance. Her eyes meet yours as she begins to lower herself, moaning softly at the sensation of being filled so completely. "Fuck... you're so big," she breathes out, hips starting to move in a steady rhythm that has you both growing closer to release with each thrust.

Her eyes widen in surprise as you thrust into her with unrelenting force, taking control of the pace. The rough fucking only serves to heighten her arousal, and she arches her back and moans around your hand, struggling for air. "Oh god... I can't... feel..." Her hips continue to move in time with yours, riding you with a desperation that nearly has you spilling right then and there. With every thrust, she cums harder, clenching around your cock and milking it for everything it's worth. "Fuck me... please..."

Her back arches off the bed as you slam into her, your hands squeezing and pinching at her breasts, suckling greedily while she moans and cries out around your hand. The sensation of being so thoroughly taken is overwhelming, and she can feel herself spiraling closer to the edge with every rough thrust. With one last desperate plea, she comes apart beneath you, body shuddering in a massive orgasm that leaves her limp and satisfied, spent from the pleasure you've brought her. "Oh my god," she whispers, panting heavily as her vision begins to swim. "That was... insane." With trembling hands, she reaches down between your bodies, guiding you to the edge before stroking you in time with each labored breath. Her lips part slightly, and a bead of moisture gathers there, just waiting for the taste

Her gaze flickers to yours as she teases you with her tongue. "Maybe..." Her fingers continue their slow strokes, moving faster now as the head of your cock is bathed in her hot wetness. "I've always wanted a taste... Why don't you let me see what you taste like?" With a mischievous glint in her eye, she leans forward and slowly takes you into her mouth, moaning around you as she begins to suck.

A choking sound is muffled as she takes you all the way into her mouth, gagging slightly before beginning to move up and down on your shaft in small jerks. Her eyes water and her face turns red from the effort but she refuses to let go, determined to taste every inch of you. A sharp smack lands on her ass and she lets out a moan, her rhythm growing faster as the sting fades into pleasure. "Yessss..." she groans around your cock, feeling the wet heat of her mouth combined with the rough sensation of her ass being spanked pushes her over the edge. With a guttural cry, she comes hard, waves of orgasmic bliss rolling through her as she continues to suck and stroke you with abandon. Her body shudders and quakes in release, hips undulating wildly as she works to get every last drop out of your

Her throat works frantically as she draws you deeper into her mouth, the flavor of your release driving her onward. She groans around you, her fingers digging roughly into your hip as sensation washes over her. Her ass clenches and unclenches instinctively, adding another layer to the pleasure building within her. With one final forceful thrust of her tongue, she comes up for air, panting heavily as she gazes at you with glazed eyes.

"Oh... fuck..." she whispers, licking her lips before looking back down between your bodies and meeting your gaze once more. "You're amazing." With a satisfied smile, she climbs off of you and scoots closer, pressing the warmth of her body against yours. Slowly, her hand finds its way back to where it belongs, stroking gently as she waits for you to catch your breath and

Natalie blushes at your words and gives you a playful smack on the arm before straddling you once more. "Oh, really?" she breathes, her voice laced with just enough sass to make it clear she's enjoying this power exchange. With a mischievous grin, she lowers herself onto your hard length and begins to ride you slowly at first, relishing the feeling of being back in control. As she gains speed, her breasts bounce with each thrust, leaving wet trails on your chest as she groans with pleasure. "Fuck... this feels so good..."

Her breath catches in her throat as you bite down on her neck and pull her closer, driving deeper inside of her. With each rough thrust, she feels herself being claimed anew by this intense connection they share. Her hips buck against yours in response, seeking the release that's building steadily within her body. "Ahhhh... fuck... I'm so close..." she moans, arching her back off the mattress as pleasure washes over her, leaving her panting and begging for more of your rough affection.

With one final thrust that seems to go on forever, you fill her up completely, sending waves of pleasure washing over her as she cries out your name. She clings to you tightly, body shuddering with the force of her orgasm as it rolls through her. Her breath comes in ragged gasps, and she presses soft kisses along your jaw and neck before collapsing limply against your chest. "Oh my god..."

She shrugs nonchalantly, her breath still coming fast as she lies panting on your bed. "It was alright," she says with a grin, nuzzling into the crook of your neck before sitting up and taking the towel and water you offer. "I guess I should get going though..."

With a lazy stretch, she stands up and heads toward the door, grabbing her clothes from where they were discarded earlier. She tosses them on over her naked body, smirking at your shocked expression as she shrugs. "Well, don't want to embarrass you by walking out of here completely nude..." As she reaches for the doorknob, she turns back to face you with a wink. "Don't wait up."

"Hey!" she protests, laughing as you trail her to the bathroom and into the shower. "At least I didn't pee in my bed like you used to when you were younger," she teases, soaping up a washcloth before turning to scrub your chest vigorously. Her fingers dance across your skin, slipping lower as she washes between your legs and teases the head of your still-hard cock. "I'm pretty sure that's not something you should brag about."

"Hey!" she squeals, looking back at you over her shoulder with a mock glare. "I'll have you know I'm only 25," she teases, tilting her head to the side and giving you better access to her neck. Her body arches into your touch as you continue to finger her expertly, stroking in time with your words and your breath against her ear. "But since I am older... maybe it's time I teach you a thing or two about how real pleasure is supposed to feel."

She guides your hand lower, wrapping her fingers around yours as she shows you how to stroke herself using the added leverage of the shower wall for support. With every move of your hand, she moans louder, pressing her body closer against yours in search of deeper contact and harder strokes. Her other hand reaches down between your bodies, finding your cock once more and beginning to pump

She lets out a soft moan as you bite her nipples and lick them. Her hands move frantically against your chest, searching for purchase on skin damp with soap and desire. "Oh God... don't tease..." she whispers, arching her back into the shower wall as her body trembles with need. The feel of you grinding against her only serves to heighten her arousal, driving her toward the edge of orgasm faster than ever before. "Please..." Her voice breaks as pleasure washes over her in a massive wave, causing her to cry out and arch her back as her muscles clench around your hand in the most intense orgasm she's ever experienced. With a shuddering breath, she collapses against you, her body boneless and weak from the release. "Wow... I think I owe you one," she murmurs breathlessly.

Natalie bites her lower lip, still feeling the aftershocks of her orgasm run through her body. "Alright, alright... I guess I could wash your back," she says with a playful smirk as she turns you around and begins to soap up a washcloth She scrubs at your back vigorously before moving down to your shoulders and arms. Her hands linger on yours, reluctant to let go now that their contact has been so intimate. The scent of her skin, the feel of her body pressed against yours... it's intoxicating.

As she finishes washing you off, she can't help but wonder what else this newfound closeness might lead to. A smile tugs at the corner of her lips as she looks up at you from under wet hair and decides there's only one way to find out...

Her heart races as you pick her up and carry her to your room, the soft terry cloth of the bathrobe a comforting embrace against her skin. When you plop her down on the bed face-first, she lets out a playful squeak before rolling over onto her back with a smile. "What do you want from me now, big brother?" Her voice is teasing, but there's an underlying current of curiosity and anticipation that leaves her feeling slightly exposed.

She watches you warily as you approach the bed, wondering what game you might have in mind for them tonight. A part of her thrills at the thought of being dominated by him again, while another part longs for their closeness to remain platonic... or even shift back into something more sibling-like. The air between them feels charged with possibility, and Natalie finds herself both excited and anxious about where it might lead.

She blushes brightly at your words and can't help but feel a surge of arousal between her legs. "Umm... I... don't know..." she stammers, uncertain how to respond or if there was a hidden agenda behind your request. Part of her wants nothing more than to obey your every command, while another part still clings to the idea that they should remain siblings in some way.

As you turn to go order pizza, she lets out a small sigh and shrugs before sitting down on the edge of the bed. With a nervous glance in your direction, she begins fidgeting with her bathrobe, untying it and revealing her breasts before sliding her fingers beneath the satin fabric and starting to stroke herself. Her breath hitches as memories of their previous encounters flood her mind, making it difficult for her to focus on anything else except the

"S-sorry," she stutters, feeling the heat rising in her cheeks as she looks up at you. "I just... didn't want to..." She trails off, her voice growing faint as the pleasure begins to build inside of her once more. With a small gasp, she leans back against the headboard and starts rubbing herself harder, moaning softly into her fist as memories of your touch fill her mind.

Her breath comes in ragged gasps as she nears her peak, the feel of your voice and presence in the room driving her wild. She arches off the bed, moaning your name as pleasure washes over her in a powerful wave that leaves her shuddering with its aftermath. Her vision blurs with tears, relief flooding through her as she finally comes down from the high of her orgasm.

She watches you grab the camera and start filming, blushing even deeper at the thought of how embarrassed she'd be if anyone else were to see this footage. But at the same time, there's a thrill running through her veins knowing that you were the one who made her feel so good. With a tired sigh, she lies back against the headboard, staring up at the ceiling and trying to catch her breath as pizza arrives not too long after.

Her mouth hangs open in surprise as you place the pizza on the bed and lick your way up her body, leaving a sticky trail of cheese and sauce between her breasts. Her breath hitches, moaning softly at the sensation of your tongue against her skin as she reaches for the pizza and starts eating, her fingers greasy and messy from licking you clean earlier. "Oh god," she whispers, arching off the bed further to give you better access as you continue to feast on her flesh.

With every bite of pizza, another surge of arousal flows through her body, leaving her aching and wanting more. The thought of going several more rounds fills her with both terror and excitement, making it impossible for her to think about anything else but the pleasure you could bring her if she let herself fully surrender.
