She lifts her arms, gingerly but not hesitatingly, like someone just waking up from sleep might slowly stretch theirs.

So cute, thinks the man sitting close in front of her on the soft, furry surface of a light-colored rug by the window of the studio apartment. She is anything but sleepy, however. Her senses are alive with a sharp tinge of desire. The man in front of her lifts her peach-colored sweater up above her arms, helping her out of it. There is nothing that she wears underneath her sweater such that this act bares in front of him her lithe, beautiful young body.

She gives him her best innocent look and makes a deliberate gesture of lifting one hand in a pawlike way to her lips and giving it a lick. So mischievous and cute - the feeling comes to him armed with a sharp edge of that old and familiar almost-icky-yet-sweet feeling he used to get for her when they spent many a debauched afternoon surreptitiously in each other’s arms.

Yet for all her frolicsome behavior and typically cute, sexually charged mannerisms, it is clear to him that years have passed since he has held her the last time. That is, aside from the previous night when perhaps deliberately she had sought the safety of darkness to give herself to him again after such a long time. It is only now, with the shafts of golden evening light pouring in through the window, sparkling in her smiling eyes, and illuminating her smooth skin that he can have a proper look at her naked body.

He can see that at thirty now Wendy is intoxicatingly sexy, effecting effortlessly a delightful feline charm that seems to be born out of both her toned, lithe figure, as well as from her general physicality and movements. Her beautiful intelligent face is as affectionate as ever, but there is something distinctly new there. It lingers in the corners of her eyes and mouth, etched in her general bearings and occasionally in the way she looks at him; it presents to him first as an amorphous novelty in her being. After he gets to better grips with it, the best way he can describe it is maturity.

She was well grown-up when he had had to leave her. But now she seems like she has already lived a life; traversed onto the other side of a phase of her life where he was absent. He does not know why, but it makes her more delicate, more inviting, almost mysterious to him.

'Mystery' is not a word Ryan and Wendy have readily associated with each other since, unbeknownst to their parents, they had started fucking in one another’s arms at the ages of twenty-one and eighteen respectively. Now as he traces his eyes down her perky breasts with her erect pink nipples, the gentle curvature of her sides, her flat stomach, he has to admit she has grown even sexier since he has last seen her. He used to love and covet her thin body, so delicate and bony in his arms. She is far from a radically changed woman now, but there is a hint of growth in everything about her. And this excites her elder brother more than she can imagine.

When he places his arm as though by instinct on the bare skin of her waist, she feels instantly drawn to the handsome, athletic man that her brother has grown older in to. He bends forward and kisses her softly on her shoulder and sniffs audibly breathing in the scent of her body. She giggles, lazily pushing him away.

The next thing to come off is his t-shirt. Wet kisses trail across his chest from where she looks up giggling at him, leaning her face into him. It feels as though a layer of nervousness has been dispersed, in exchange for the relative safety of familiarity, and Ryan smiles as well.

His cock is thick, hard, and full in her palm once his shorts are taken off. Resting his hand on her waist, he kisses her. Her light brown hair brushes against his face soft and fragrant. Her skin is velvety and cool to his touch, her body delicate like butter.

When they part lips and she smiles at him again, it is a clear acknowledgment of the increasingly evident fact now that the magic is still there. It is etched in clear language in the dance of their psyches and across the surfaces of their skins, burning warm in the pit of their stomachs. To each of them, the other looks like they’re glowing with desire and shameless lust, and it only serves to make them hornier for one another.  

Ryan presses a couple of cushions underneath him and sits leaning back against the warm glass walls of the sliding French window. When he lifts his sister onto his lap, she angles herself close upon his cock, catching the glorious diffused light through the glass on herself, almost daringly hoping it now makes her even more naked and more visible to him, for better or for worse.    

When she sits down on him, making him pierce through her folds and reach deep inside her body, she thinks maybe it is for the better after all. Her hands resting on his shoulders and being in turn held lovingly by her waist, she can feel him growing bigger inside her. She merely sits like this for the next few seconds, feeling comfortable and excited staring into his eyes while a part of him rests snug inside her. He caresses her sides softly, just the way he used to. Somehow it sends a tickling sensation through her and she giggles contracting her body and crossing her arms across herself as if by a biological reflex for self-protection. Ryan reaches forward and hugs her, and as though by instinct beginning to scratch an itch unawares, she starts moving her hips slowly within his embrace.

To each of them, it feels like something clicking into place, and the relaxed sensuality of the moment morphs readily into the urgency of sex. Removing himself from the embrace, Ryan leans back against the wall allowing his cock to better enter his sister’s pussy. His index finger is inside her mouth which she sucks slowly in rhythm as she rides him. He pulls the finger out and lets it trace down her chin and throat, marking its path across her smooth skin with her saliva. It traces down in between her breasts and across her gently curving tummy down to her belly button, leaving a wet line. He puts his thumb inside her mouth next and bathing it with her saliva he brings it to the base of her body where she grinds gently on his cock. The first time she feels his slippery thumb caressing her clitoris she gives a little yelp of pleasure and starts riding him a little faster.

One arm crossed around her back, the other in service of her stiff clitoris, Ryan begins to thrust upwards, meeting her deeper inside each time. Wendy still looks into his eyes. Her breathing intensifies with each thrust. She is deliciously lovable and delicate and as though stretching her pussy wide and fucking her deep is not enough, Ryan caresses her back, her chest, her breasts, brushing across and then pinching her pert nipples. He kisses her body and her cheeks repeatedly as they fuck with increasing need and urgency.

Ryan feels like he can spend a happy eternity with his sister riding him naked like this as long as he does not cum by some magic spell. Knowing no such spell could possibly work with her anyway, and anticipating her legs getting tired Ryan scoops her up in his arms and rests her gently on her back on the rug. His cock bathed in the wetness of her cunt and throbbing close to orgasm, now hangs over her underbelly while he breathes in deeply and exhales, not wanting the wonderful experience of fucking his sister to be cut short by desperate cumming.

Still unused to the experience he finds himself in the middle of, Ryan simply stares at Wendy lying bare against the velvety fur of the rug. Both their skins glisten in the orange sunlight from the fresh gloss of sex.

She looks up at him standing on his knees over her and watches him make the signs with his hands, “You look like someone to die for.”

She laughs, slapping his thigh in a gesture of banishing any seriousness from the comment, and then lifting her own hands makes the signs in turn, “Just fuck me already.”

Once more their lips lock in fervent desire; he is on top of her, his chest brushing against her breasts while he thrusts into her until his groin makes a soft thump against hers. Each time it stretches her wider. Ryan can hear the excitement in her breathing, in the soft moans she lets out close to his ear every time he pokes deep inside her pussy.

Holding her in his arms and pressing close to her body, this movement inside her feels so terribly natural and satisfying that he thinks whether by God or by chance, he has been designed, even programmed for this very specific task. It feels almost holy, a thing he is meant to do. She holds him by his arms, and again by his shoulder. Now she caresses his neck, then her fingers dig into his back until the pleasure is too great to express, such that she simply lays her arms limp by her sides and pours her heart and soul into the delight of being fucked by Ryan who now rises above her and starts thumping into her base, fingers digging into her waist and tummy.

His sister is generally never loud, though he knows the cues of her body and of her breathing to know when she is feeling particularly pleased. But now her cry is deep and throaty and pierces through the studio apartment, resonating with the writhing of her body, the contractions of her stomach bringing her to glorious orgasm under his grip. Her eyes are watery when they look up at him. Ryan leans forward, kisses her, and brushes her hair back lovingly.

Her look conveys everything he needs to know, but she lifts her hand anyway to make the gesture: her thumb sticking out and fingers extended over her chest, she moves her hand in a circular motion, clockwise, twice.

“Please,” she says to him.

More, please.

She holds him in a soft, lingering kiss while he fucks her. It feels good again, so good she wants to spring a voice and tell him so before she remembers she does not need to. He understands in a way other men have not. Suddenly she is immersed and drenched thoroughly in the remembrances of their early years. Of fucking in the privacy of his room and making each other cum again and again, discovering the wonders of sex and attraction together. Sometimes guided by him, but often taking pleasure in guiding her older brother herself.

Memories of orgasms given and received, and of other kindnesses become one with the urgent, burning sensation inside her pussy and on her clitoris under the pressure of his thumb, until she is close to cumming again.

The drunken stupor and cover of darkness on the previous night had hardly allowed her to see him when he had felt at his most vulnerable. It makes her want even more to see him cum for her now.

“Please,” she says again, “Please cum for me.”

Cum for her. Cum for your sister.

Ryan does not want to but his cock is on the brink of exploding, he pulls out of her and spurts dollops of thick, warm cum on her navel and stomach, while still squeezing inside his groin and steeling himself to hold on for longer. Wendy’s face is instantly tinged with a shade of scarlet, which Ryan can tell is not from embarrassment but from excitement. He just about stops himself from orgasming full tilt, so that when he slides his somewhat smaller but cum glazed cock inside of her again she purrs audibly with a surprised look on her face.

Her hands tug at his and he is instantly leaning close in on her. She kisses him more passionately than she has the entire afternoon. Her lips on his, her hands caressing his sides, it is a message of love and affection that resonates sharply inside him. He is slippery and swift inside her, and the more she hugs him and loves him the broader he grows, beginning to stretch her again.

Wendy starts moaning and squirming in Ryan’s arms like she never has before. Is it the distance from the sexual life they used to share that makes this afternoon so enchanting? Maybe she has missed him so all these years and now she is letting it all out? Or is it that she is merely louder in lovemaking now? Ryan cannot tell but the sound of her voice moaning to his needy thrusts inside her, inspire in him emotions he does not remember ever feeling before.

He hugs her tight while fucking her harder. The fresh cum on her tummy rubs against his skin as their bodies grind together, further smearing his cum across both their bodies in conjunction with their movement, and they relish in the feeling shamelessly. He can see beads of sweat on her face when he kisses her next. As their lips touch, his tongue enters her mouth, and at the instant when the tips of their tongues touch, a shivering tingle leads her to what feels like an eternity of glorious squirming and writhing in pleasure in her brother’s arms. Feeling Wendy beginning to cum underneath him, Ryan too lets go and a sensation of a beautiful immersion brings him to orgasm, the tip of his throbbing cock spurting thick loads of cum deep inside his sister’s pussy.

Both of them are too stunned to speak for several seconds afterward. When finally Wendy makes to say, “thank you”, she is interrupted by the sensation of someone’s hand flowing through her hair in an affectionate gesture. She looks up to find Don, her husband behind her. Neither of the siblings would have heard or noticed when the handsome young host had come back from work, turned the key, and entered the apartment. To each of them now he smiles and nods, before leaning down to kiss his wife.

“You two seem to have had a fun time,” he says to her, “Guess I missed the party.”
