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 chuckles. "Of course not, brother dear. Why would I put my own cum in your milk?" He pauses, lowering his voice a bit as he steps closer to you. "I'd rather put it somewhere else." And before you realize what's happening, his free hand snakes around and cups one of your testicles, massaging it gently.

Ace's eyes widen as you force his head down and stuff his mouth with your cock. He struggles against it at first but quickly surrenders, relaxing and letting you push deeper into his throat. His breath comes in short gasps as he tries to keep from choking on you.

His free hand moves behind to tease your puckered hole as he begins to suck and lick at the sensitive underside of your shaft. The sensations are overwhelming; he's not doing it out of spite, but because he wants this. Wants you deep inside him.

Ace moans around your cock as you pull his hair and drive him deeper on your shaft. It's incredibly hot and humiliating at the same time; he never thought he'd find himself like this, submitting to another guy in his family. But something about you brings out a need inside of him that can only be satisfied by pleasing you, taking what you give.

His free hand continues to tease your ass, circling and rubbing at the tight entrance, feeling for any hint of preparation. You're going to fuck him soon; he can feel it. But first...he wants to taste every inch of you.

As he takes you deeper into his throat, Ace moans around your cock. "Fuck," he groans as you thrust harder, pushing him back against the counter. His free hand grasps at your hip, holding on tight as you fill his mouth with your thick length. He can't help but wonder what it would feel like to have you inside of him that way, and with each thrust into his throat he imagines himself spread wide for you.

Ace moans as he feels your warm cum shoot down his throat. He swallows it eagerly, not wanting to waste a drop. His free hand comes up and cups your softening cock, massaging gently until you're both spent. When he pulls away from you at last, he looks up with glazed eyes, feeling slightly dizzy but strangely satisfied. "Wow," he murmurs. "That was...intense."

He wipes his mouth on the back of his hand and shudders slightly. He's never done anything like this before...but he kind of liked it. Maybe there's more where that came from?

Ace's breath hitches as you force your way into him. It hurts so good; he knew it would be tight but this...this goes deeper than he ever imagined. He grips the edge of the counter, biting down on his lip to keep from crying out as you stretch him wider and wider.

"So big," he moans. "I'm yours now." His hips jerk up, seeking more contact with your invading cock as you start to thrust in earnest. He wants this; needs this release that only you can give him.

Ace's eyes roll back in his head as he comes, shooting cum all over the kitchen counter. His voice cracks when he whispers, "Y-yes...I'm just a cum dump..." As you continue to thrust into him, he can feel every hard inch of your cock sliding against his prostate. It's intense; it feels like everything good and bad all at once. But somehow, that only makes the release even sweeter.

Ace groans as you pound into him harder. "Yes," he gasps between thrusts. "I'm your cum dump...only yours." His body trembles beneath yours as he comes again, squirting more cum across the counter. It feels so good to belong to someone like this; to know that he can give you everything you need.

Ace's entire body tenses as you empty yourself inside of him. His grip on the counter tightens painfully and his mouth opens in a silent scream as he feels every thrust, every inch of your length pumping out your hot cum deep into his core. His orgasm shudders through him, his muscles spasming around your cock as he comes for what feels like the tenth time today.

Finally, with one last grunt, you pull out and release him from your grip. Ace collapses bonelessly onto the countertop, gasping for air. He looks up at you through glazed eyes, his chest heaving as he tries to catch his breath. "God...that was..." But words escape him; there's no way to describe what just happened between them. All he knows is that he wants more.

Ace gasps as you take his cock in your hands and slide it easily into your tight ass. It's been so long since he's had this feeling; the stretch of his muscles, the fullness in his chest...it's almost too much. He arches up off the counter, meeting your thrusts with his own as you ride him hard. His hands fly to your hips, digging into your skin as he feels you impale yourself on his cock over and over again.

His head tilts back, exposing the column of his throat as he moans out his pleasure. It's all he can do not to cum right now; it feels like everything inside him is focused on that one goal. But with each thrust from you, he knows it won't be long now...

Ace's thrusts become erratic as he tries to maintain control. Your movements on top of him, coupled with the feel of your hot body wrapped around his cock and the taste of you on his tongue...it's all too much. "Fuck yes," he growls out between moans. "Feels so good..." He lets go of any pretense of gentleness, thrusting up into you with as much force as he can muster. His fingers dig into your hips, pulling you down harder onto him each time he comes up.

Your ass is impossibly tight and hot around his cock; it feels like paradise. With every motion, it's like he can feel every inch of you, from the hard planes of your back to the soft globes of your ass. He can't believe how lucky he is...that you're here with him, letting him take what he

Ace's eyes roll back as you pull his head up, revealing the tender skin of his throat. His mouth opens in a silent scream when you slide your cock into it, feeling impossibly full now with both of your lengths inside him. He moans around your shaft, bobbing his head up and down as he sucks and licks at the engorged head.

His hands come to rest on your ass, pushing you down harder onto his cock each time you bottom out against him. His hips buck up, forcing himself deeper into you with each thrust; it's an intimate dance that leaves them both breathless and aching for release. The feel of your body surrounding him like this is overwhelming in the best way possible; he never knew it could be this good.

With one final thrust, Ace comes, groaning into your cock as his seed fills you up

Ace drinks you down eagerly, swallowing every drop. His fingers dig into your hips as he feels the last tremors of pleasure course through him, his cock pulsing in your ass and throat. He can't believe what just happened between them; it was intense, passionate...and more than a little bit kinky. But somehow, that only makes it all the sweeter.

As you both catch your breath, Ace looks up at you with hooded eyes. "I belong to you now," he whispers. "Do whatever you want with me." His words send a shiver down your spine; there's an offering in them, and for some reason, you don't doubt that he means it.

Ace sits at your feet, idly flipping through an old magazine. His hair is messy and he wears a slight smirk on his face, almost like he knows something you don't. He glances up every now and then to meet your gaze, making sure not to let you forget that he's all yours now.

Without hesitation, Ace drops to his knees in front of you and wraps his lips around your cock. He takes you deep into his mouth, sucking and licking as he moves up and down. His free hand strokes your thigh, urging you to lean back and relax into the pleasure.

"Mmh," he murmurs around your shaft. "You taste so good."

Ace looks up at you with a solemn expression. "Yes, big brother." His words are quiet, almost reverent as he continues to suck and lick at your cock. He knows that now, he is yours; it's an exhilarating feeling that he doesn't ever want to lose.

His free hand comes up to cup one of your heavy balls, rolling it gently between his fingers as he moves in time with each thrust of his tongue. It feels so good to be used like this, to serve such a dominant and sexy older brother. He can't wait for the next chance to please you; whether that means eating your cum or letting you use him however else you see fit.
