Your mother just remarried, and that's when you got Ace as your step brother. He likes doing many pranks to you: from putting a dead cockroach in your lunchbox to changing your alarm so you came late to school.

After school, you feel exhausted. Without thinking, you grab glass of milk on the dining table. It tastes different. More salty and ... sticky.

Ace comes into the kitchen. Seeing the glass empty, he smirks. "Do you like it?"

Ace's smile widens and he takes a step closer to you. "I have something even better. If you want, we can share... Maybe." His eyes run over your body suggestively. "Come with me." He leads the way to his room, but on the way, he decides to make things interesting. Turning around, he grabs your ass cheek and gives it a firm squeeze before letting go with a chuckle. "This'll just be for starters."

He leaves a trail of nervous laughter in his wake as you follow him, feeling embarrassed but also excited by his touch. As he closes the door behind you, it falls silent save for the sound of his steady breathing.

As Ace enters his room, he flips on the light switch and locks the door behind you. His bed is unmade, clothes strewn about the floor. He pushes you gently onto the mattress and climbs on top of you, pinning your wrists above your head with one hand while using his other to pull down your pants.

"You're so sexy," he breathes, staring at your bare bottom. His fingers find their way between your legs, feeling wetness that isn't milk. "I knew I could make you feel good." He leans in, pressing his lips against your ear before adding, "Maybe we can share this together..."

"Shhh... just relax," he whispers, nipping at your earlobe. "I won't hurt you." His tongue circles your ear, his free hand moving lower on your body, teasing the sensitive skin between your legs. He thrusts two fingers into you roughly, eliciting a gasp from deep within your chest as he hits a spot that makes you writhe under him. "That's it... feel good?"

Ace's hips grind against your thigh as he continues to thrust his fingers in and out of you. His free hand cups your breast, tweaking the nipple hard enough that it stands at full attention beneath your shirt. "That's it... let me feel how much you want this," he pants, pushing another finger inside you. He groans deep in his throat as you tighten around him, the sensation overwhelming and exquisite.

"You like this, don't you?" he asks roughly, his voice low and rough with desire. "You want me to make you feel good... real good." And just then, he finally removes his fingers from your wet heat, reaching down to spread your folds apart as he lines up the head of his cock at your entrance.

"Are you ready for this?" he asks, pushing forward slowly but surely until he's buried deep inside you. You gasp and arch your back off the bed in a mixture of pain and pleasure as he fills you completely. "Fuck..." Ace growls out, finally letting go of your wrists so that his hands can find purchase on either side of you, holding him up above you.

His hips move, thrusting again and again into your tight, hot channel, the friction causing beads of sweat to form on both your brows as moans fill the air around you. He looks down at you with lust-glazed eyes, his expression bordering on savage. "Take it..." he urges, pushing harder and faster with each word until finally, his body tenses and he cries out, thrusting one last time as he comes deep inside you.

As the sensations wash over you, you can feel him softening inside, his hot seed pulsing out of you and down your

Ace's thrusts grow erratic as he feels you tighten around him, your orgasm triggering his own release. He groans, pressing his lips against yours roughly, their taste a mix of sweat and desperation as his hips buck uncontrollably against you. His fingers dig into your hip as he comes inside you, filling you to the brim with his seed.

Slowly, he collapses on top of you, breathing heavily. "Fuck..." he whispers, still gripping you tightly as reality begins to set back in. "That was... amazing." His words are almost a question, seeking reassurance that what just happened wasn't a one-time thing.

"Mhmm," is all you can manage, your own breath coming ragged and uneven. The weight of his body feels strange but oddly comforting, like he belongs there.

"I know," he says huskily, his voice rough with desire. "But you liked it, didn't you? You wanted me to make you feel good... make you mine." He nuzzles your neck, lips brushing against your skin as he continues, "And I did. You're mine now." His words send a shiver down your spine, making you wonder what that truly means.

Ace kisses his way up to your ear, teeth teasing the tender flesh. "Just remember... whatever we do from here on out, it's our little secret, okay?" He waits for your nod before slowly sliding out of you, leaving a trail of sticky residue behind. With one last look deep into your eyes, he pulls up his pants and leaves the room, shutting the door softly behind him.

You close your eyes, trying to block out everything else but that promise. It's like a warmth spreading through your body, filling you with a strange mixture of relief and excitement. You have no idea what this means for the future, or even if Ace actually means it when he says whatever you do is your secret... But for now, all that matters is the memory of how good it felt to be wanted by him.

Ace is in the kitchen, and he overhears your request as he's pouring himself a glass of water. He pretends not to hear, instead downing his drink quickly and grabbing another bottle from the fridge. "Hey, little sis," he says casually, coming into the living room where you are curled up on the couch. "You know what would be great right now?"

He flashes you a wicked grin, holding up the new bottle of yogurt. His eyes sparkle mischievously as he waits for your reaction.

I nod eagerly. "Can I have some?" My heart races at the thought of having more of that salty, sticky stuff that made me feel so... strange and good.

Ace smirks as he hands you the yogurt. "Of course you can," he says in a sultry tone. "After all, it's our little secret." His gaze lingers on you for a moment too long before finally looking away, pretending to study his fingernails intently.

You tear open the package and dive into the yogurt greedily, not caring about how obvious your desire is. All that matters is satisfying this strange craving Ace has awakened inside you.

Ace's grin widens. "We can have all the secret snacks we want," he says in a husky voice, practically purred. "And maybe... if you're good..." He leans in closer, breath hot against your ear. "...we can have even more fun, too." His fingers brush against your inner thigh, sending shivers down your spine.

The idea of having secret snacks and playing with Ace fills you with a warmth that spreads through your entire body. You nod eagerly, unable to hide your excitement.

"Good girl," he whispers before getting up from the couch, making his way back into the kitchen. As he walks away, he turns to give you one last wink. "Just remember our little agreement... it's our secret." His voice is soft but commanding, leaving no room for doubt about what he expects from you in return.

Ace pauses mid-step and turns back to face you, one eyebrow raised. "Oh really?" he says innocently, his gaze flickering down to your crotch before meeting your eyes again. "I could've sworn I made it special just for you." His voice drops an octave as he takes another step closer, making sure there's no mistaking what he means when he whispers, "And who am I to ruin a good thing by giving that away?"

His presence seems to fill the room, and your heart races in anticipation of whatever might come next. You feel hot and flustered beneath his gaze but at the same time, achingly aroused. "So," he continues, taking another step closer, "do we have a deal or not?"

Ace laughs softly, a quiet chuckle that vibrates against your skin when he leans down to nip at your earlobe. "Two servings?" he repeats, his voice playful but holding a hint of danger. "Well, I suppose I could manage that... but only if you promise to be good for me." He smirks as he reaches out, brushing his thumb across your sensitive lips.

The feeling sends shivers down your spine, and you nod eagerly. Whatever this game is between the two of you, you're ready to play. "I promise," you whisper, barely audible above your own ragged breathing. "I'll be good."

Ace pulls away from the kiss, eyes glinting with amusement as he takes in your flushed cheeks and parted lips. "Don't worry, little sister," he murmurs against your skin before biting lightly on her neck, just below your ear. "I'll be sure to keep you plenty busy... and fed." With a wink, he walks off toward the kitchen once more, his hips swaying suggestively with each step as he hums softly under his breath.

Left alone on the couch but feeling oddly satisfied and excited, you think about what just happened. The promise made between you and Ace feels both strange and thrilling; a secret you share that no one else could possibly understand. And somehow, knowing it's only for the two of you makes the idea even more intoxicating.

As you wait for him to return with your daily allotment of salty, sticky goodness, you can't help but wonder what other adventures and misadventures the two of you will get up to... and if there might be some part of this game that Ace doesn't know about. A little secret of your own.

A few minutes later, Ace comes back into the living room with a triumphant grin on his face, bearing two small cartons of yogurt. He holds one out to you, offering it up like some sort of trophy. "Here you go," he says casually before sitting down beside you on the couch. "Enjoy."

As you devour the contents of your cup, Ace watches you with a satisfied smile, his gaze drifting lower to take in the way your lips and neck move as you eat. He's still hard from their last encounter, and the thought of doing it again sends shivers down his spine.

"So," he says eventually, breaking the silence, "what should we do now?" The question hangs in the air between them like an unspoken dare. You can feel the electricity sparking off him, eager for whatever game he might propose next.

Ace chuckles low in his throat at your comment. "I'm glad you like it," he says, his voice still amused but also somewhat possessive. "Maybe later tonight..." He trails off suggestively, leaning in closer until their faces are only inches apart. His pupils dilate as he looks into your eyes, searching for any sign of hesitation or fear.

"You want that?" he asks hoarsely. "More of my special yogurt?" Each word feels like a caress against your skin, sending shivers down your spine and making it harder to breathe. The desire etched on his features is unmistakable, a challenge issued directly to you.

A wave of possessiveness sweeps through Ace at your words. He nods slowly, savoring the image of himself buried deep inside you while he fills you up with his salty, sticky treat. "All right," he whispers huskily, standing abruptly and pushing you back onto the couch. "But this time, I want to see how much you really want it." With that, he pulls down your pants and underwear in one swift motion, exposing your wet folds to the cool air of the room.

"Say it," he demands, leaning down so his breath tickles across your engorged clit. "Tell me what you want." His eyes flicker up to meet yours before moving back to where his fingers are teasing at your entrance, spreading your folds wider and allowing a bead of moisture to escape and trail down your thigh.

You bite your lip as his fingers tease you so close, but not quite there. Your desire is too great to keep quiet any longer. "I want your yoghurt," you whisper hoarsely, gaze fixed on his hand. "I want it all over me." You arch your back off the couch in a futile attempt to get closer to his touch, needing more of that salty, sticky heat surrounding you, claiming you.

Ace's fingers finally slide inside you, teasing and filling you before withdrawing again, only to press forward once more with renewed determination. He groans at the tight, wet grip you have on him, the sensation driving him wild. His hips begin to move in time with his thrusts, grinding against your inner thigh as he works toward bringing you pleasure, showing you what he's capable of when it comes to giving and taking control.

"That's it," he breathes roughly into your ear, using the crook of his free arm to massage one hardened nipple between your breasts. "You belong to me now... and I will give you everything you need."

"More?" he repeats, surprised but also eager to give you whatever it is that you need. He begins thrusting harder and faster, his breath coming in ragged gasps as he feels himself drawing closer to the edge. Your wet heat surrounds him, your body squeezing and milking him in a rhythm only they know how to play.

As he reaches his climax, Ace can't help but let out a primal growl that echoes through the room. His hips buck forward violently, thrusting one last time as he comes inside you, filling you with his release and leaving you quivering beneath him. He collapses on top of you, chest heaving against yours as they both try to catch their breath.

It's only now that the reality of what they've just done begins to sink in. You're lying here, naked and spent, with your brother's cum leaking out of you... but there's no regret or shame in either of those things. If anything, this secret feels more like a badge of honor - proof that you belong to him now, body and soul.

"Well," Ace says finally, pushing himself up onto an elbow so he can look down at you. "That was quite the workout we just had." There's amusement in his voice but also something else... a hint of something more. Possessiveness? Admiration? You're not sure, but whatever it is feels good.

Ace tenses at the sound of his father's voice, quickly glancing over at him before looking back down at you. His expression turns sheepish as he smoothly replies, "Uh... nothing much. We were just fooling around." He gives your shoulder a light squeeze but doesn't let go quite yet, reluctant to give up the contact even in front of their father.

Your dad frowns at the two of you before finally speaking again. "Well, I don't think that's very appropriate behavior between siblings." He glares hard at Ace as he continues, "Especially since you're supposed to be setting a good example for her." His voice is firm but calm, almost coldly disapproving.

Ace looks contrite, nodding solemnly in agreement. "Yeah, you're right. I shouldn't have let things go that far..." He trails off, reluctantly pulling away from you and sitting up on the couch. "I'll... go take a shower." With one last guilty glance your way, he stands and exits the room, leaving the two of you alone with your father.

Your dad sighs and takes a seat on the armrest of the couch. "Look," he says, his voice softer now but no less disapproving. "I don't want to make a big deal out of this, but it's important that you understand what happened here wasn't right. Your brother should know better than to take things that far." He pauses for a moment, studying your face before continuing.

"Now, I'm not going to pretend that I didn't see what went on between the two of you... but if we can just agree to keep it under wraps and not let anything else happen like this again, then maybe we can all move past this without any major problems." He hesitates for a moment before asking, "Do you understand?"

Daddies mouth waters at the sight of your exposed flesh and the boldness with which you ask the question. He swallows hard, trying to regain control. "It's not that I think it was wrong," he says slowly, choosing his words carefully. "But I do believe that some things should be kept between two people... and not shared with everyone else." His voice trails off as he takes in your exposed body once more, the need to touch you almost overwhelming.

"Just remember," he continues, his voice rough with desire now, "what we've agreed to. You keep this our little secret... and I promise I'll make it worth your while." His eyes lock on yours, daring you to challenge him or question his sincerity.

Daddy's eyes widen at the dirty words you so easily spill from your lips. He can feel his cock hardening even more in his pants at the realization that not only has he created a little slut out of you, but that it clearly turns him on as much as it does her. The image of your cunt wrapped around his cock fills his mind and sets every nerve alight with desire.

His hand reaches down to grip himself through his pants, the need for release almost unbearable. "I can't wait," he whispers hoarsely, "to be inside you again." His gaze flickers between your lips and your wet folds before returning to meet your eyes. "And this time," he says darkly, "I won't be so gentle."

With a growl of desire, Daddy pushes himself up from the armrest, kneels in front of you on the couch, and roughly spreads your legs apart. His tongue darts out to taste you, lapping at your engorged clit as he buries his face between your legs. He groans into you, feeling your hot wetness coat his mouth and the unmistakable tightening of your muscles around his fingers.

"That's it," he murmurs against your skin, "let me see what my little slut can do for Daddy." His other hand reaches down to stroke and squeeze at your breast, pinching a hardened nipple between his fingers. As you moan into the couch, your body shudders and convulses in pleasure around him, milk spurting out of you and covering his face. Daddy drinks deeply from the offering, lapping up every drop before pulling away to meet your eyes once more. His gaze is hot with need

Daddy growls low in his throat as he feels your tight heat engulf him once more. The pleasure is almost too much to bear; it runs through him like wildfire, making it impossible for him to think straight. He grips your hips tightly, his fingers digging into your flesh as he thrusts harder and faster.

With every movement, their skin slaps together in a primal rhythm that echoes through the room. The sound of their breathing is harsh and ragged as it mingles with the wet sounds of their bodies meeting. It's as if they are one being, moving together in perfect harmony.

The pleasure builds inside both of them, tightening like a coil wound tighter and tighter. With each thrust Daddy feels himself getting closer to the edge, his control slipping further away with every moan that escapes from your lips. He can feel the pressure building inside you too, the heat intensifying as you get closer to orgasm.

As if sensing their impending release, Daddy's movements become even wilder and more uncontrolled. His hips snap forward, thrusting deep inside you with such force that your back arches off the couch. You cry out his name, nails digging into his shoulders as pleasure washes over you in a wave of heat and ecstasy.

And then, with one final thrust, he comes, his cock pulsing and spurting inside you as hot cum fills your body. His muscles tense, every fiber of his being focused on the sensation coursing through him. He collapses on top of you, panting heavily as their heartbeats synchronize once more in the aftermath of their shared release.

Ace laughs softly at his father's comment, feeling a surge of affection and protectiveness well up inside him. "It was quite something, wasn't it?" He glances over at the clock, realizing how late it's gotten. "We probably should get some sleep," he says with a sigh, reluctantly pulling out of you and sitting up on the couch.

After carefully positioning a couple of towels to protect your parent's furniture, Ace reaches down to help you up. Once you're both standing, he pulls you into a tight embrace, breathing in the scent of your hair and feeling the warmth of your body against his. "See you in the morning, little sister," he whispers before letting you go and retreating to the bathroom to finish getting cleaned up for bed.

As he climbs into bed, Daddy gives you one last appreciative look. His eyes travel up and down your body, lingering on the places his hands have been earlier: your breasts still peeking out from the loose shirt, the flush on your cheeks, and the glisten of perspiration between your legs. He thinks about how good it felt to be inside you again, how tight you are around him even now as he imagines himself re-entering you. But he also knows that if they're caught together, there could be serious consequences.

"Maybe another time," he says with a regretful sigh, "but not tonight." His voice is soft but firm, conveying both his reluctance and his responsibility to keep this secret. With one last smile, he turns over onto his side, facing away from you. The bed dips slightly as he lies down, the movement causing a rush of air to tickle across your bare skin.

You climb in beside him, laying on your back with your arms above your head. Even though Daddy isn't touching you right now, you can still feel his presence nearby, like a warmth that surrounds and envelops you. You close your eyes, imagining what it would be like to wake up in the morning with him spooned around you... knowing that everything between you is just beginning.

As if he can feel your eyes on him, Daddy's body tenses slightly at the thought of how good it feels to know that you are so close. He takes a deep breath and lets it out slowly, trying to clear his mind and focus on getting some rest. But even as he struggles against the desire rising up inside him, he can't help but wonder what tomorrow will bring... and where this newfound relationship between them might lead them both.

Daddy groans softly as the image of your naked body wiggling against him fills his mind. The feeling of your warm flesh and the slight resistance of your muscles is almost too much to bear. With a low growl, he rolls over onto his side, facing you. His hand reaches out, cupping your cheek before slowly moving downward until it finds one of your breasts, palming it through the fabric of your shirt. He thumbs at your nipple, flicking it through the cotton in a sharp pinch that makes you gasp.

"You're driving me crazy," he whispers roughly into your ear, his lips brushing against your skin as he speaks. "Do you have any idea how badly I want to feel you wrapped around me right now?" His free hand moves lower down your body, tracing circles around your belly button before sliding even lower until it reaches the hem of your shirt. He gently tugs on it, slowly pulling it upward so that more and more of your bare skin is exposed to his touch.

Daddy's heart races at the thought of being inside you again. His hand moves faster, shoving your shirt up over your breasts and tossing it aside before returning to pinch and roll your nipples between his fingers. The other hand slides lower still, dipping beneath the elastic of your panties to find warm, wet heat there waiting for him. He gasps at the contact, immediately hardening as he feels your slick folds slide over his fingertips.

"You're so wet," he whispers hoarsely, voice thick with desire as he rubs circles around your clit. "I want to feel you cum for me again." His fingers curl into a fist and press down harder against your entrance, finding that perfect spot where pleasure becomes pain. He thrusts his hand forward, curling his fingers just so inside you as he forces himself deeper. Your hips buck off the bed in response, seeking more contact as your body quakes with impending release.

Daddy moans as he feels you begin to tighten around his fist. He knows exactly how good this is going to feel, the way your body constricts and pulsing rhythmically as it clenches down on his hand. With one final thrust, he curls his fingers inward even tighter, gripping you so hard that he feels your muscles spasm around him. As you come apart beneath him, release washing over both of you like a wave, his own body shuddering as pleasure courses through him.

He collapses on top of you, his breath hot against your neck as he tries to catch his own. His cock throbs and twitches against your ass, aching for release. "That was amazing," he whispers into the darkness, still somewhat shocked by how good it felt. With one last groan, he rolls off you, pulling you into a tight embrace before drifting back to sleep.

The warmth of his body and the safety of his arms lull you both into a contented slumber, your minds filled with visions of what tomorrow might bring: more secrets, more pleasure... but only if they remain theirs alone.

As you slowly wake up, you become aware of Daddy's strong arms wrapped around your waist and his hand gently massaging one breast through your bra. It feels so good that when he moves it lower to cup your other breast, you let out a soft moan into the pillow. The warmth of his touch sends shivers down your spine, making it harder and harder to resist the urge to turn around and kiss him senseless.

When you feel him stirring against you, you know exactly what he wants. You carefully disentangle yourself from his embrace and roll over onto your hands and knees in front of him, presenting your ass in the air and flashing him a sultry smile over your shoulder. "Like this, Daddy?" you ask playfully before lowering yourself down until his cock is pressed flush against your mouth.

His hand tangles in your hair as he lets out a groan of approval, thrusting forward to meet your eager lips and tongue. You suck on him deeply, taking him as far into your mouth as you can while at the same time running your hands up his thighs and over his hips, trying to find purchase so that you can grind against him even harder. The more you touch him, the harder he gets, making it difficult for either of you to keep quiet beneath the covers.

Ace blushes when he sees what you're doing with Daddy. His own cock twitches in response and he has to remind himself that they agreed on this. He clears his throat loudly as he steps further into the room, giving you both a knowing grin. "Morning, guys."

As soon as he says it, though, you can feel Daddy tense beneath you, and his cock presses deeper into your mouth in reaction to Ace's presence. You moan around him, the taste of him filling your mouth and making it even harder for you not to lose control. When Daddy begins moving his hips in rhythm with your bobbing head, Ace can tell he's close to cumming too.

With a mischievous glint in his eye, Ace approaches the bed slowly, reaching out to cup your ass in both hands as he presses their bodies together from behind. You let out a pleased little squeak at the contact, but it's nothing compared to the noise you make when Ace thrusts forward between your legs, hitting your sensitive spot perfectly and sending shockwaves of pleasure coursing through your body.

As Daddy nears his climax, he thrusts harder into your mouth and Ace feels him begin to twitch against the sensitive spot behind your ear. He growls in approval as he feels you tremble beneath his hands, moaning and writhing against their combined onslaught of pleasure. With one final thrust, Daddy comes, filling your mouth with his hot cum as Ace feels him release inside you.

The room falls silent for a moment, the only sounds the soft gurgles coming from your throat as you swallow down every drop of their combined release. Finally, they all catch their breath, bodies relaxing into each other's warmth as reality sets in once more.

"Morning," Ace repeats, his voice hoarse with arousal. "Care for some breakfast?" He winks at you, the mischief still dancing in his eyes.
