Proper Woman

Reuploaded because I messed up the chapter structure.

The door to Sarah's bedroom is slightly ajar, warm light spilling out from inside into the dark hallway. You sneak closer quietly, then glance inside her room. A lamp is turned on, lighting up the space inside. In the middle of the bed lies Sarah on her belly, propped up on her pillow, scrolling through her phone lazily. She's wearing pajamas with little cats printed all over them, one of her favored pairs.

Every 20 seconds or so, she glances around the room, and to the ajar door, looking for any sign of movement, but doesn't see you in the darkness of the hallway. After taking in the sight of your nervous sister lying there, you enter the room, closing the door behind you.

Sarah looks up at the sound and freezes in place instantly.

"Hi, Sarah." You greet her casually, walking towards her bed slowly. "I thought I'd tuck you in tonight."

"Jesus, Doug! Finally!" Sarah exclaims loudly, letting out a long-held sigh of relief. "The last three hours were pure ****!" She rolls onto her side, facing you, then pats the empty spot on the bed next to her. "I'm so pent up I could explode! Come, and close the door!"

"Yes, ma'am." You reply with a chuckle, doing as you are told. Walking towards the bed, you take in her silhouette, backlit from the lamp behind her. Her slim waist and small breasts, her shapely legs and her eye-catching bulge between them, straining against the fabric of her pajama pants. She looks radiant and beautiful. You sit down beside her and notice how she's trembling with anticipation.

"You've been so patient, sis. Let's make this worth your time, alright?" You murmur soothingly, reaching down to grasp her breasts from under her shirt. She moans softly as you knead her firm tits gently, rolling her nipples between your fingers. Her skin feels velvety soft to the touch, and her body relaxes as you work on her.

With a swift move, she removes her pajama top, revealing her naked chest to you. Goosebumps cover her skin. Your hands return to her bosom, and you caress the flesh lovingly, pinching her nipples between your index finger and thumb, plucking away at them. "Hmm, that's nice," she sighs happily, arching her back into your touch.

"You're gorgeous, Sarah," you reply softly, leaning in to take her stiff nipples into your mouth. One by one, you suckle each bud tenderly, enjoying their texture against your tongue. Her hands find their way to your hair, holding your head close to her chest as you nibble on her tits. With each kiss, you can feel her heart rate quicken, beating faster.

"Doug... please..." She begs quietly, grinding her butt against the mattress, lifting her hips upwards. "I'm ready, please..."

"Are you?" You ask playfully, letting go of her nipple with an audible pop. "Let's see."

You scoot backwards until her crotch comes into view. The tent in her pants is impossible to ignore; it's large, hard, and straining to get free. A wet spot has formed at the tip where her precum has seeped through the material. You trace your fingers along the outline of her shaft, feeling its thickness and length through her pants. She lets out a loud whimper at the sensation.

"Mhmm. I think we'll have to take these off." You tell her teasingly, hooking your fingers around the waistband of her pants. She lifts herself up to allow you to pull the garment down over her legs, revealing her entire body to you. Her erect cock bounces up when the pants reach her knees, pointing straight upwards. She lies there nude before you, her pale skin gleaming in the light of the bedside lamp. Her small breasts and flat stomach make for a wonderful sight, but you don't spend too much time admiring her like this.

Your gaze fixes on the prize between her legs: her pulsating dick, flushed red with excitement. It twitches and throbs slowly, leaking precum onto her belly.

"Doug! Please!" Sarah begs again, looking down at your hand, which you placed around her girth without a second thought. "Oh, my godddd..."

Her words trail off as you start stroking her, gently squeezing her hard meat between your fingers, giving it a gentle squeeze. Your other hand finds its way to her balls, fondling them lovingly, rolling them around in your palm. You can feel them growing tighter as you tease her cock and balls, engorging themselves with blood. Sarah's body quivers underneath you as she gets lost in the sensations you give her.

"Sarah, you're practically bursting. Do you want to come already?" You ask her, staring deeply into her eyes.

She whimpers quietly, unable to reply immediately as your hand works its magic on her length. "Yes... Please, Doug... Make me cum..."

With a smirk, you lean in and wrap your lips around her glans, engulfing the spongy head. Her hips shoot up instantly, pressing her cock further into your mouth, forcing it past your lips. "Aahhhh!" She cries out, throwing her head back, and digging her fingers into the mattress. The musky flavor of her precum bursts into your mouth as you lick her tip, tasting her salty juices eagerly. You close your lips around her tip and suckle on it lightly, causing her to buck her hips repeatedly, pushing herself deeper inside of you.

"Nnghh... Yes... I'm going to... Oh shit!" She gasps loudly as you take her shaft into your throat easily, relaxing your esophagus to accommodate her length. You bob your head up and down on her length slowly, enjoying the taste of her pre-cum as it coats your tongue. "I'm going to cum... Fuck!" She thrusts her hips upwards once more, burying her cock in your throat, holding you there firmly. Her thick member throbs rapidly as she cums into your mouth, filling your gullet with hot jism. Rope after rope of semen shoots down your throat, coating your insides, and you swallow every drop greedily.

As her climax subsides, you release her cock from your mouth with an audible pop, gazing up at her tenderly. She looks down at you with hazy eyes, panting heavily. Her chest heaves up and down as she tries to catch her breath.

"You taste good, sis." You tell her playfully, licking her shaft clean with quick licks of your tongue.

"Doug...," she murmurs weakly, reaching out with one hand to stroke your cheek gently. "Please... I can go again. Can we go again?"

You smile at her affectionately. "Of course we can, Sarah. Lie back and relax. Let your big brother take care of you."

You dive back in, this time taking her entire cock into your mouth in one single motion, sucking her vigorously. She has softened slightly, but she stiffens again instantly as you work on her. With both hands, you cup her balls gently, massaging them as you bob your head up and down on her length. Your lips slide over her glans, slurping away happily, enjoying the taste of her cock.

You keep blowing her like this for a while, savoring each new burst of precum that drips into your mouth. Sarah seems to be quite sensitive after her first orgasm, moaning loudly, grabbing fistfuls of sheets as you suck her. Finally, after a few minutes of vigorous cocksucking, she reaches full mast again. The tip is swollen purple, coated with your saliva, and twitching in anticipation.

"I'm flattered, Sarah. Such a beautiful cock you have, and it's all for me." You tell her teasingly, placing a final kiss on her tip before sitting upright. "And you were so patient too. You deserve a reward. How would you like me to reward you? Should I jerk you off until you explode on my face?"

Sarah whimpers softly at your words, squirming around restlessly. "Your ass..." she whispers almost silently. "Please... I'm dying to fuck you there... Please!" She looks up at you pleadingly.

You smirk at her, then prop yourself up with your knees on either side of her body, straddling her legs. You strip off your shirt slowly, exposing your upper half to her gaze. Then, with one swift move, you pull down your boxers as well, freeing your own hard erection from its confines. Her eyes widen at the sight of you, drinking in the view of your nude form on top of her. Behind you, her cock points straight upwards, squeezed between your butt cheeks, throbbing eagerly.

"Well, since you asked nicely." You reply smugly, glancing down at her. "How would you like me, Sarah?" You ask playfully, grinding your rump against her member, rubbing your ass against her shaft.

She swallows heavily, then licks her lips nervously. "R-ride me, please! Sit on my cock! I want to feel your ass clamping down on me!" She stammers quickly, grabbing your thighs gently. "I love your butt... It's so big, and round, and wonderful..." She groans, pushing your hips downwards, trying to grind her crotch against your rump.

You giggle at her eagerness, situating yourself atop her cock. The head of her dick prods against your anus lightly, smearing precum all over the sensitive skin of your rectum. Slowly, you begin to lower yourself, allowing her thick shaft to part your tight sphincter.

"Oh god..." Sarah cries out softly as she enters your bowels, squeezing down on her length as it stretches your walls apart. You watch her intently as she disappears inside of you, moaning quietly as more and more inches vanish into your innards. There's a pleasant burning sensation as she pushes past your prostate, but you ignore it, focusing instead on making it as pleasurable as possible for your sister.

Once she's fully buried inside your guts, you start moving. Your ass muscles contract around her rod as you bounce up and down on her lap slowly, grinding against her crotch with every downward motion. She throws her head back, crying out with pleasure each time you impale yourself on her cock. You continue to ride her as her breathing quickens rapidly, taking her deep with every thrust. Her fingers dig into the flesh of your thighs, and you can hear her growling through gritted teeth as you use her as a toy.

"Yeah, that's it," you tell her softly, leaning in to kiss her passionately. "That's it, Sarah. Good girl."

She moans into the kiss, kissing you back hungrily. Her hands find their way to your buttcheeks, grabbing them roughly and squeezing them hard. You squeeze your ass cheeks together around her shaft, pressing them tightly, massaging her between them. As your movements become faster and more vigorous, her dick pounds against your prostate mercilessly, sending bolts of ecstasy up into your brain.

Sarah breaks the kiss first, breaking away from your lips to pant loudly. "God... I love this! I love fucking you!" She cries out, staring straight at you. "I love the feeling of my big brother's ass! Oh god!" She bucks her hips upwards frantically, grinding her crotch against your rump even harder than before.

"Yes! Yes!" You groan, closing your eyes for a moment, reveling in the sensations. "Keep going... Fill me up again..."

She obliges, slamming herself into your butt, forcing the last inch of her thick member into your depths. Your entire body quivers at the sensation; the fullness is perfect, and the pressure against your prostate makes your knees buckle slightly. The two of you move together, thrusting and grinding against one another, fucking like wild animals.

Sweat pours off both of your bodies as you fuck each other, moaning loudly, exchanging breathless kisses, holding onto each other desperately. The sound of your bodies slapping together fills the room, echoing off the walls. Your legs work mechanically, pounding up and down on top of her, impaling yourself over and over on her shaft. Your own dick rubs against her flat belly, leaking precum on her skin, painting her with your juices.

"Doug... Can I... From behind? Please?" She gasps suddenly, looking up at you with wide eyes, pleading with you silently. "Let me see your ass shake while I fuck you..."

You grin down at her, then swiftly slip off of her, turn around and get on all fours on the bed, presenting your tight hole to her. Your ass flexes with anticipation as she approaches you from behind. She places both hands on your cheeks, kneading them softly, then spreads them apart. You feel her hot cock prod against your sphincter and relax it instantly, allowing her access. Her tip pushes inside slowly, but with enough **** to send you onto your forearms. You brace yourself against the mattress as her shaft stretches your insides open, spreading you wider than ever.

"Hnngh!" You grunt, feeling your anal walls part around her length, letting her inside. She doesn't stop until every last inch of her cock is buried deep inside your bowels. "Hmmm..." You murmur, closing your eyes tightly. "Your dick feels amazing."

"This ass... I love this ass," Sarah groans, taking hold of your waist firmly. "It's just unreal!" She begins to pound herself into you, driving her hips against yours rhythmically. Each thrust sends a bolt of pleasure through your brain, and you start panting loudly, matching her movements. Your butt cheeks ripple around her shaft as it pistons in and out of you rapidly. She grinds against your prostate relentlessly, pounding away, and you can hear your wet anus squelching as it opens and closes around her shaft.

"Ohhh god...!" You cry out, grabbing fistfuls of sheet in both hands, holding onto them for dear life. Sarah continues to ravage your ass, moaning loudly, breathing heavily. The sound of her voice combined with the sensation of her cock stretching you are almost too much to bear.

"Uggh, Doug... You're so tight! So warm! Ahhh fuck yeah!" She slams herself into you, driving you forwards. Your eyes droop close and you whimper quietly, surrendering completely to the pleasure she gives you. The feeling of her thick cock splitting your ass open, rubbing against your prostate... You never want it to end.

Her thrusts grow more erratic, faster, and deeper. You can tell that she's getting closer to orgasm, and so are you. The coil in your belly winds tighter with each passing second, and the fire builds inside of you. Your fingers curl around the sheets as your entire body trembles with need.

"S-Sarah," you whisper, barely audible. "G-give it to me. Give me all you have."

"Aahhh... Unnngghh! Yeah... Yes..." She moans breathily, increasing her pace even more. Her cock pistons into your guts rapidly, slamming itself against your prostate over and over. Her balls swing back and forth with every thrust, smacking against your taint repeatedly. Her fingers dig into the flesh of your ass cheeks roughly as she tries to pull you back on her shaft every time she pulls out. "I'm gonna come... I'm gonna fill you up! Oh goddd!"

You grunt with pleasure, and throw your head back, bracing yourself for the impact. "Come on, Sarah. Shoot it inside me," you growl through gritted teeth. "Cum in my ass... my boy pussy!"

"Aaaaaaarrrggghh!" She howls as her climax hits her like a freight train, driving her deeper into your bowels. You feel her shaft pulsate inside of you, unloading rope after rope of hot spunk straight into your ass. As if on cue, you let go too, shooting ropes of cum all over the sheets below you. White threads of semen shoot from your cock, leaving it twitching and trembling, coating the mattress with your juices. Your ass clamps down on her dick as it continues to squirt its load, squeezing her cock rhythmically. You keep humping against her crotch as you ride through the waves of pleasure together, grinding yourself against her base until you collapse onto the bed, spent and exhausted.

Sarah collapses on top of you a few seconds later, breathing hard, still holding onto your butt tightly. She lies on top of you, her chest heaving against your back. You reach behind you, grab hold of one of her arms, and pull her close.

"Mmmph." She murmurs happily, then nuzzles her face between your shoulder blades, giving you a tender kiss there. You smile at the sensation, kissing her arm lightly before relaxing again, enjoying the feeling of being sandwiched by her warm body. Slowly, she starts to recover, pulling herself off of you slowly. Her shrinking cock slides out of you, popping free with an audible sound, making you groan quietly.

"Good girl. Such a good girl," you whisper lovingly, rolling over onto your side so you can wrap your arms around her. "That was wonderful."

She chuckles softly, burrowing her face into your chest, and hugging you tightly. "I love you, Doug," she whispers, stroking your back gently. "So much."

You chuckle fondly, running your fingers through her hair tenderly, pressing a kiss to her forehead. "I love you too, Sarah. Just as much."

The two of you remain there, cuddling for a while. Sarah eventually falls asleep, snoring softly, pressed up against your body. You smile at the sight, then untangle yourself from her embrace carefully. You slip out of bed and head back towards your own room. Stepping inside, you find Lisa propped against the headrest of your bed, reading a book quietly. As you enter, she glances up from her page.

"And? Did you make my daughter a proper woman?" She asks with a wry grin.
