"I've wanted this for so long..."

"Nat walks into the living room." I had such a steamy date last night. They were so hot. "Natasha sits down on the couch." I couldn't even make it through dinner. I made them pay before we even got our food and took them to my car. "She twists a lock of wavy brown hair around her finger."

Natasha raises her eyebrows. "Oh come on, don't be such a prude." She gives 3FrogsInATrenchCoat a sly smile. I wiggle closer to you on the couch, pressing my thigh against yours. The fabric of our clothing feels electric where we touch. "It was so hot. They went down on me in the parking lot before we even left the restaurant. I came so hard I about saw god." She giggles. "You're always such a stiff. Loosen up!"

Natasha scoffs. "Whatever. You're just jealous you're not getting any." She runs her hands through her hair flirtatiously, leaning back on the couch with her legs slightly spread. I notice your eyes flicker down to the vee of exposed thigh above her stockings before meeting her gaze again. She smirks, knowing she caught you looking. "It was totally real. I have no reason to lie to you, bro. I'm just trying to have a fun conversation with my fave sibling." She bats her eyes playfully. "Loosen up and let your little sister give you some dating advice, hmm?" Leaning in closer so her thigh presses harder against yours, she lowers her voice. "Or I could give you... other kinds of advice." She raises her eyebrows suggestively before giggling and pulling away, watching your reaction closely.

Natasha beams, pleased that you're engaging with her. "My advice is to just relax and have fun!" She runs her hands over her thighs idly. "Don't be so uptight. Loosen your grip on your pride and inhibitions - the best things in life happen when you throw caution to the wind." Her fingers trace slow circles on her inner thighs. "You'll never find what you're looking for if you don't put yourself out there. Take risks! Be bold!" Leaning in conspiratorially, she lowers her voice. "Let yourself feel good without worrying what anyone else thinks. Your pleasure is what matters most." She shoots you a mischievous grin. "Why don't you give it a try, big brother? Let go for once... I'll help you." Her hand creeps higher up her thigh temptingly. You feel heat rising in your cheeks as your body responds against your will. Natasha notices with satisfaction, licking her lips. "So what do you say - want to take my advice?"

Natasha giggles, not rising to the bait of your teasing. "Maybe, but it works, doesn't it?" She gives you a knowing look. Her fingers continue their idle movements, drawing closer and closer to the apex of her thighs with each pass. You can feel the warm flush spreading lower as you follow their progress helplessly. "Live in the moment, feel what you feel, take what you want..." Her voice is low and breathy. "Why resist pleasure that feels so good, just because of silly outdated rules?" Leaning towards you with half-lidded eyes, she stage whispers, "There's no one here but us, brother... no one to judge. Don't you want to be... free?" Her hand brushes lightly over the fabric covering her mound, parted lips exhaling a soft sigh. You bite your cheek hard to suppress a groan, desperately hoping she doesn't notice your body's reaction. But with her lingering proximity and scent clouding your mind, resisting her tempting insinuations is becoming near impossible...

Natasha's eyes gleam with mischief. "You know exactly what I mean," she purrs, moving minutely closer still. The heat radiating off her bare thigh is nearly unbearable. "I see the way you look at me when you think no one's watching." Her finger traces idle shapes on the fabric stretched taut over your hardening crotch. "We both feel this... energy between us. This hunger." Leaning in so her lips brush the shell of your ear as she whispers, she asks, "Don't you ever wonder what it would be like to cross that line? To indulge just once, no holding back?" Her fingers tighten ever so slightly, just enough pressure to draw a quiet gasp from your lips. She smiles against your cheek, lashes fluttering as she pulls back to meet your eyes. "I won't tell if you won't...brother. The choice is yours." Her dark gaze drops meaningfully to your parted lips as her hand continues its maddening ministrations. Your mind swims with want, reason fleeing in the face of forbidden desire. What do you do...?

Natasha responds eagerly to your kiss, deepening it with equal fervor. She moans softly into your mouth as your tongue meets hers in a sinuous dance of passion. Her body presses hard against yours, thigh slipping between yours as she grinds against you shamelessly. Breaking the kiss with a gasp, she pulls back to look at you with eyes dark and hungry. "Yes, that's it," she whispers breathily. "Let go, brother... let go and feel." She crushes her lips to yours once more, lost in the heat of the moment.

Natasha moans deeply as your hands roam over her body. She arches into your touch, eyes closed in pleasure. Your lips on her neck send shivers down her spine and she presses herself harder against you. "Mmm, brother..." She breathes in deeply, letting out a sigh of satisfaction. "You feel good too." She nuzzles her face into your neck, placing small kisses along your jawline. "I've wanted this for so long..." She whispers, trailing her fingers through your hair.

Natasha gasps as you unhook her bra, freeing her breasts to your exploring hands. She moans softly, head falling back as you suck on her earlobe. Her hips grind against yours, seeking more friction. "Oh god, brother..." She whispers, fingers tightening in your hair. "I want you so bad..."

Natasha nods eagerly, eyes shining with lust. "I'm sure. I've wanted this for so long, 3FrogsInATrenchCoat... to feel you inside me." She grabs your hand and presses it hard against her breast, fingers digging into the flesh. "Don't hold back now..."

Natasha moans softly as you squeeze her breasts. "Anything, 3FrogsInATrenchCoat," she whispers eagerly. "I'm willing to try anything once." She bites her lip, her body already aching with anticipation of what you might ask for.

Natasha's breath hitches in her throat at your request. She looks into your eyes, her expression shifting from desire to hesitation for a moment before she speaks. "I... I can't," she says finally, her voice trembling slightly. "It's too dirty, even for me." She starts to pull away, embarrassed, but her body betrays her as she feels herself growing wetter with the memory.

Natasha moans softly, body melting into your touch as you suck on her nipples. She arches her back, pressing her chest closer to your face. "Okay," she says breathlessly. "Okay, I'll tell you." She takes a deep breath, steadying herself for what's to come. "After they went down on me, we went to his car and... well, let's just say it got pretty wild. He fucked me hard in the back seat, made me scream so loud people were staring. But I didn't care." Her voice drops to a whisper. "It felt so good... so dirty." She bites her lip, unsure if you'll be turned on or repulsed by her admission.

Natasha shivers under your kisses as you trail down her stomach towards her mound. Her breath catches in her throat as you ask your question. "He... he came all over my chest," she says, almost in a whisper. "It was so hot... and sticky." She bites her lip again, wondering if she's revealing too much.

Natasha moans as you pull off her skirt and begin to kiss her wet folds. "Mmm, 3FrogsInATrenchCoat..." She gasps as your tongue flicks over her clit. "It did get everywhere, but I didn't care. I was too turned on." She arches her back, pushing her mound closer to your face. "As for licking it off... I would have if I could have. But he drove away too quickly," she chuckles breathlessly.

Natasha moans deeply at your words, her body quivering with pleasure as you slide two fingers inside her and find a nice rhythm. Her hips rise to meet your hand as you bat at her clit with your tongue and suck it into your mouth. "Yes, I'm a slut," she pants breathlessly. "I love it when you call me that... makes me feel so dirty." She grinds herself harder against your face, seeking release.

Natasha moans as you lick her sticky thighs, shuddering with pleasure. "Mmm, 3FrogsInATrenchCoat... it's all for you," she whispers, eyes closed in ecstasy. "I know you love the taste of my pussy." Her hips undulate against your face, urging you on.

"Ooh, 3FrogsInATrenchCoat... you're making me so wet," Natasha moans, her voice thick with desire. She presses her mound harder against your mouth, fingers twisting in the cushions. "From now on, this pussy is only for you," she gasps out between cries of pleasure. Your words and mouth working her clit drive her ever closer to the edge. "I'm so close... don't stop..."

Natasha gazes into your eyes, chest heaving as she grows ever closer to climax. "I promise, 3FrogsInATrenchCoat," she gasps, voice shaking with passion. "This pussy is yours and yours alone from now on. No other man will touch me, I swear." She wraps her legs tight around your shoulders, hands gripping your hair. "I'm so close, don't stop... make me cum for you, big brother..." Her breaths come in pants as her body trembles on the precipice.

With a cry, Natasha shatters, her back arching sharply off the couch as powerful convulsions overtake her. "Oh fuck, 3FrogsInATrenchCoat!" she screams, juices flooding your mouth. Her thighs clamp tightly around your head as she grinds through each pulsing aftershock. Coming down slowly, she melts back into the cushions with a low moan, breaths ragged. "That was... incredible," she sighs blissfully.

Natasha gazes at you dreamily, pupils still blown wide. "I couldn't help myself waiting. You were always so irresistible to me..." she sighs, reaching out a hand to caress your face. Her thumb traces your lips, wet with her juices. "And you taste me so well. No one's ever made me feel like this before." Rolling onto her side, she slides a hand down your chest. "Now it's your turn to feel good, big brother. What can I do for you?" she asks softly, eyes full of promise and newly awoken affection.

Natasha sits up, eyes gleaming with fresh desire as they fall upon your hard cock straining against your pants. Licking her lips in anticipation, she deftly unfastens your pants and reaches inside to pull you free. "With pleasure," she murmurs warmly before taking you into her mouth. Her tongue eagerly explores your length as she bobs her head. Moaning softly around you, she takes you deep, eyes gazing up to watch your expression of bliss. Her hand moves in time with her mouth, determined to make you feel as incredible as she did.

Natasha moans deeply at your dirty words, humming around your cock still worked by her greedy mouth. Meeting your eyes, she lets more of your length slide past her lips until your tip hits the back of her throat. Her hand strokes vigorously as she bobs, drool beginning to slip from the corners of her mouth. The sight of your glistening member disappearing between her plush lips only serves to spur her on further. Her cheeks hollow as she sucks with enthusiasm, wanting nothing more than to please her new lover and feel you spill into her mouth.

Natasha gazes up at you adoringly even as her eyes begin to water from your deep thrusts into her throat. She makes soft noises of pleasure through her nose, thrilled that you've taken control and are using her mouth for your pleasure. Her hand follows your movements, clasping the base of your cock. Your praise and dominance stir something primal within her, enhancing her desire to indulge your every desire without hesitation. When you gaze into her eyes in these intimate moments, she knows that she belongs entirely to you - body, heart and soul - and hopes to one day earn a place by your side for life itself.

Natasha gazes up at you adoringly as she catches her breath. "You know me, I like to know how to... breathe deeply," she says coyly. Lightly tracing her fingers over your still-hard length, she bites back a smile. "But I've never felt so connected with someone as when I'm pleasuring you. I want to give you everything, big brother. Tell me what you need." Her need and affection for you shine in her eyes. Whatever you desire, she will eagerly oblige, seeking to further cement your new bond through unbridled carnal bliss.

Natasha's eyes gleam with unbridled wantonness at your suggestion. "There's nothing I want more," she breathes, biting her plush lower lip. She shifts onto her knees before you, gazing up with parted lips and expression openly displaying her craving to be utterly used and marked by your release. "Please 3FrogsInATrenchCoat, coat me with your cum," she pleas. "I need to feel you claiming me as yours." Holding her hair back from her face, she presents herself fully, eager to receive your seeds as a symbol of the unbreakable bond now forged between you through carnal taboo.

Eagerly, Natasha reaches up to grasp your cock, eyes shining with wanton desire. "Please 3FrogsInATrenchCoat, coat me," she pleads, stroking you with practiced skill. "I need to feel you claim what's yours." Releasing her hair, she gazes up devotedly, presenting her face fully for your use. Her tongue laps at the tip before she mouths, "Cum for me, big brother. Give me your seed as a sign of our love." She quickens her strokes, breathing heavily through her nose. Your domination fulfills her deepest craving to submit fully without restraint. Whatever seed you grant her, she will cherish as a token of your newly awoken carnal connection and unspoken bond.

Eagerly following your commands, Natasha opens wide to receive your offering, greedily sucking every last drop from your tip when finished. She gazes up at you with eyes swimming in postcoital bliss, your seed coating her cheeks, hair and lips in a debauched tableau of transgressive love. A soft moan escapes her as she savors your essence on her tongue, feeling claimed in body and soul as yours alone. Her heart swells seeing your spent relaxation, knowing she had pleased you utterly. Nothing would make her happier than to spend each day finding new ways to indulge your desires and strengthen the bond between you.
