What Her Husband Discovered About Her Brother That Night

The party was celebrating nothing in particular, just the urge to go out on an ordinary Saturday. After twenty-eight years of marriage, Rubén still looked at Carmen with the same devotion as on the first day, though for some time that devotion had taken on a new edge: he liked to imagine her desired by other eyes, to imagine other cocks hardening at the sight of her passing by, other fingers brushing that round ass he knew by heart.

At the nightclub they ran into Dani, her younger brother. The boy was many years younger than them; for the couple, he was almost like a son. Carmen spoiled him and Rubén advised him with the quiet authority of someone who acts as a father without actually being one.

The hours passed amid drinks and laughter. The music got louder and so did their confidence. From the table, Rubén watched his wife dancing with Dani. Carmen moved with overflowing looseness, her generous body swaying to the rhythm of the bass.

The dress, clinging to her skin with sweat, outlined the contour of her broad tits, heated to a warm pink by the heat and alcohol, with her nipples standing hard beneath the fabric every time she turned. Rubén went over to her on the dance floor and wrapped an arm around her waist while his brother-in-law laughed, a little drunk.

—Are you having a good time, my love? —he whispered in her ear.

—Wonderful —Carmen replied, radiant, hugging her brother with that same old affection—. It’s been ages since we went out like this, just the three of us.

But Rubén sensed something else. He saw how the tipsy boy could not help letting his gaze slip to his sister’s cleavage, to those tits bouncing with every step. Her innocence contrasted with the tension her husband was beginning to feed on purpose.

By closing time, Dani could barely stand.

—We can’t let him go back alone in this state —Rubén declared, exchanging a loaded look with his wife—. He’s coming home to sleep.

***

When they got back to the apartment, the atmosphere mixed exhaustion with the euphoria of the early hours. Dani was barely coordinating, so Carmen, with her usual protective instinct, asked her husband for help.

—You take him to the bathroom, get him under a cold shower and it’ll pass a bit. I’ll make some coffee —she said, adjusting the dress that still showed the blush of her cleavage.

Rubén took the young man to the bathroom. As he helped him undress, he was stunned. He hadn’t expected to find something like that in someone from his own family. Hanging between the boy’s legs was a colossal cock, thick even at rest, with heavy balls to match, a size he had trouble processing. The glans, broad as a small fist, peeked from under the foreskin with brutal fullness.

He left him under the stream of water and came out of the bathroom almost out of breath, with a grin of pure disbelief and his own cock starting to stir inside his pants. He went straight to the kitchen, where Carmen was pouring the cups. He came up behind her, wrapped his arms around her hips, and spoke into her ear in a tone halfway between joking and filthy, pressing his budding erection against his wife’s ass.

—You won’t believe what I just saw in there. Your little brother is hiding an animal between his legs. A cock that’s terrifying.

Carmen let out a nervous laugh, convinced he was exaggerating.

—Don’t be silly. He’s still just a kid —she replied, though her cheeks began to flush.

—Nothing about him is a kid, I assure you —he insisted, laughing—. Your brother got lucky in the genetic lottery. He’s got a cock that would make more than one woman cry. Way better than either of us could have imagined.

She covered her face with her hands, feeling the heat rise up her neck to her ears and, without meaning to, a wet tingle beginning to settle between her thighs. She remembered the jokes they sometimes shared in bed about size when they watched some porn video, when she admitted that imagining a monstrous cock opening her up turned her on, but having the subject be her own brother left her in an almost comic state of shame.

—I can’t believe you’re telling me this —she exclaimed between muffled laughs—. He’s my brother, shut up already!

—You should have seen my face —Rubén persisted, amused by her reaction—. I was speechless. Mouth hanging open like an idiot.

***

The kitchen became the stage for a comparison as absurd as it was exciting. Rubén, the image burned into his retinas, would not stop gesturing while she tried to serve the coffee with her hands trembling from laughter.

—Listen, I’m not exaggerating —he said, pushing a cup aside and picking up a pepper grinder, one of those thick, sturdy ones—. See this? Well, it’s about this wide, or more. It’s a solid cock, I swear. A log.

Carmen stifled a laugh with her hand over her mouth. Her broad tits rose and fell with her laughter, shaking the rosy neckline under the kitchen light, and beneath the dress she could feel her panties getting wetter and wetter.

—Stop it, for God’s sake! —she begged, though her eyes gleamed with a curiosity she could not hide.

—And in length… —her husband rummaged in a drawer and pulled out a rolling pin—. Let’s say it’s not far off this. I had it a handspan away while helping him with his pants. And that was soft; imagine it hard.

She froze, the coffee pot suspended in midair. The mental image of her little brother, whom she had always looked after, compared with the tools in her own kitchen, left her speechless. The contrast between her usual modest nature and those graphic descriptions was creating an electric atmosphere that was soaking her cunt without permission.

—It can’t be… You’re exaggerating because of the drinks —she managed to say, her face red as a poppy—. Nobody has that, especially not him.

—I promise you it’s more impressive than any cock we’ve ever seen in a video —he insisted, moving closer and noticing her breathing quicken—. And we’ve got him right there next door, in the shower. With that monster hanging down to mid-thigh.

Carmen lowered her gaze to the floor, unable to meet his eyes, feeling an unfamiliar tingle travel from her stomach down to her clit. The laughter was beginning to turn into a tense silence, while the sound of water in the bathroom took on absolute prominence and she found herself wondering, against her will, how her brother might look right now, with that huge cock hanging between his legs while the water ran over him.

***

Possessed by the kind of teasing they had cultivated for years in private, Rubén set the rolling pin on the counter and pulled out his phone with a conspiratorial smile.

—You don’t believe me? Then I’m going to take him a clean towel and snap a sneaky picture —he whispered, so close she felt his breath—. So you can see I’m not exaggerating a single millimeter of that cock.

Carmen froze, her heart galloping against her chest.

—You’re crazy! You can’t do that —she protested in a murmur, though she did not lift a finger to stop him—. It’s disrespectful… and he’s my brother!

—It’s just for us, love. A secret between you and me, like always —he replied with a wink, already heading toward the hallway.

She remained leaning on the counter, clutching an empty cup in both hands, feeling how the dress stuck to her sweat-soaked ass and something more. She heard her husband’s footsteps, the click of the bathroom door. The water kept falling, and the image of the pepper grinder and the rolling pin would not stop spinning in her head, mixed with an impossible fantasy: her brother’s cock opening her wide open.

This is wrong, he’s my little brother, she thought. But the curiosity Rubén was infecting her with was stronger than her usual shyness. Without even noticing, she slipped her hand under her dress and confirmed what she already suspected: the panties were soaked, the cunt swollen and throbbing. She stayed there, in utter silence, waiting for proof that that “animal” was real.

***

When Rubén came back, he had a triumphant smile and his phone screen turned against his chest. He walked up to her, still leaning on the counter with her face flushed.

—Get ready, because you won’t believe this —he said, turning the phone around.

Carmen covered her mouth with one hand, but her eyes locked onto the image. Reality surpassed any comparison with the kitchen tools. It was a tremendous cock, of a thickness that seemed impossible, powerful even at rest, with fat balls hanging beneath it like two ripe fruits. The glans, even relaxed, had an obscene size.

—My God… it’s an animal! —she whispered, breaking into laughter from sheer embarrassment as she felt a jolt between her legs—. It can’t be. How can he have that cock tucked away and we never noticed in all these years?

Her shyness was crumbling in the face of the photo’s filth. She leaned closer to the screen, forgetting for a moment who it belonged to, seeing only a colossal cock that made her mouth water.

—I told you —her husband laughed, enjoying her reaction and discreetly rubbing the bulge he could no longer hide—. That blood runs strong.

She could not stop staring, alternating between nervous laughter and a fascination that made her wet her lips and squeeze her thighs tightly together.

—It’s too thick… —she murmured, now more serious, her breathing ragged—. If that cock gets hard, it has to be outrageous. I don’t know how he fucks with that without splitting someone in half.

Rubén noticed how his wife licked her lips and decided it was time. He grabbed her ass with both hands, squeezing her thick cheeks over the dress, and bit her neck.

—Let’s go to bed —he growled in her ear—. I won’t last another minute.

***

The tension from the kitchen carried into the bedroom like a fire. Dani was already snoring in the guest room, oblivious to the whirlwind he had unleashed, but the image of his enormous cock was still burned into Carmen’s mind.

As soon as they closed the door, Rubén took her with an urgency they hadn’t felt in years. He yanked the dress off her in one pull, exposing those broad tits he adored, the nipples so hard they looked ready to burst. He pulled down her soaked panties and brought them to his nose, breathing deeply.

—You’re dripping, slut —he told her, voice rough—. Dripping for your little brother’s cock.

Carmen tried to protest, but he had already thrown her face down onto the bed, ass up. He spread her cheeks and drove his tongue between them, licking from her asshole to her clit, tasting all the wetness running down the insides of her thighs. She clung to the sheets and moaned into the pillow, biting it so she wouldn’t scream.

—Shh… your brother will hear you getting off like this because of him —he whispered between licks, sinking two thick fingers into her soaked cunt while he kept licking her ass.

Carmen came almost instantly, squeezing her husband’s fingers with the walls of her pussy, biting the pillow to muffle a cry. But he gave her no respite. He flipped her onto her back, spread her legs wide, and took out his cock, harder than ever.

—Suck me first —he ordered—. Pretend it’s his.

She did not hesitate. She knelt on the edge of the bed, grabbed her husband’s cock with both hands, and took the whole thing down her throat. Rubén watched her through half-closed eyes, seeing how his wife, always so modest, was sucking his cock with a hunger he had never known. He took her by the hair and began to fuck her mouth, driving in and out hard, while she drooled in streams over her tits.

—That’s it, my little slut… imagine it’s your brother’s monster cock opening your throat.

Carmen moaned around a mouthful of cock, choking on pleasure. When he felt himself about to cum, he yanked out and threw her back down. He grabbed her legs by the ankles, lifted them until they were pressed to her ears, and slammed his cock into her in one single thrust.

—Ah, fuck! —she moaned, biting her lip to keep from screaming.

He started fucking her hard, the wet sound of her soaked pussy echoing through the room. Every time Carmen tried to cry out in pleasure, he covered her mouth with his hand or with a deep kiss. Her tits bounced with each thrust, and he bent his head to suck her nipples hungrily, biting them until he made her tremble.

—Tell me you want it —he whispered between strokes—. Tell me you want your brother’s huge cock buried all the way inside you.

—Yes… yes, I want it —she confessed between gasps, unable to hold back anymore—. I want that monster cock inside… I want it to split me in two.

Rubén almost came right then and there at hearing her. He flipped her over again, put her on all fours, and gripped her wide hips with both hands. He buried his cock in her from behind, with brutal thrusts that made her big ass slam against his pelvis with an obscene sound. He gave her a couple of loud slaps that left her cheek marked red.

—Look at that ass you’ve got, whore… made for a cock like his to fuck.

Carmen came again, trembling from head to toe, her cunt dripping onto the sheets. And again. And again. She lost count of how many times her body shuddered while the forbidden fantasy seeped into every moan. When Rubén could take no more, he flipped her onto her back, straddled her tits, and shot ropes of cum over her face and cleavage, splashing her open lips. She stuck out her tongue and licked up the thick semen while looking at him with glassy eyes.

Hours later, soaked and catching their breath, they lay embraced in the dark.

—Admit it, today you were on another level —he laughed quietly, giving her a little nudge—. Are you going to tell me it wasn’t because of the photo?

Carmen hid her face in the pillow, dying of laughter and embarrassment.

—You’re impossible… —she managed—. But fine, I confess. I couldn’t get it out of my head. Every time you fucked me, I imagined his. Tomorrow I won’t be able to look at him without thinking of that rolling pin between his legs.

***

The next morning, Dani said goodbye with a quick coffee and a hurried farewell, barely remembering anything from the night before. As soon as the door closed, Rubén turned to his wife with a loaded look.

—Come on, get dressed. We’ve got a mission —he said—. We’re going to find a toy that looks like the cock your brother has. I want to see whether that cunt of yours can really swallow it whole.

Carmen covered her face, letting out a laugh of disbelief.

—You’re out of your mind! There’s no way that would fit me, not in three lifetimes. Haven’t you seen the thickness? It would split my cunt in half.

But he did not back down. He stroked her broad hips and those firm thighs that had always been his downfall, sliding his hand down until he brushed her sex through her pants.

—Look at you, darling. You’ve got a body made for fucking, a huge ass, tits that ask for trouble, a cunt that swallows whatever is given to it. You’re an imposing woman, not a girl. If any cunt can take that cock, it’s yours.

She fell silent for a moment, biting her lip while feeling the heat run down her legs at the challenge and her cunt beginning to wet again. The idea was starting to beat common sense.

—I don’t think I can, really… —she murmured, now less certain—. But fine, if you insist so much, we can go look. Just look, okay?

Rubén let out a triumphant laugh, knowing he had her convinced.

***

They arrived at the shop with their hearts racing. Carmen walked with her head down, hiding her blush, while he pulled out his phone with complete naturalness. In the special sizes section began the most surreal game of their marriage: rows and rows of silicone cocks, some more monstrous than others, hanging from hooks like trophies.

Rubén would pick up a model, hold it next to the photo on the screen, and compare the angle.

—No, this one’s long but it lacks girth. Your brother’s cock is more substantial —he commented in a low voice, while she wanted the ground to swallow her and at the same time felt her clit throbbing inside her panties.

—Put that away, please! —Carmen whispered, looking around, though she could not help noticing the dimensions of what was in front of her, imagining each one going all the way inside her.

She picked one up with trembling hands, feeling the weight and thickness. She had to spread her fingers as far as they would go to wrap around it. The silicone balls hung heavy and realistic. A sigh escaped her, and Rubén caught it instantly.

—You like that one, huh, slut? —he whispered in her ear, pressing himself against her ass—. You’re already imagining how it’s going to split you open.

After several comparisons, they found the winner: a medical-grade silicone cock, heavy, in a very realistic color, with marked veins, a swollen glans, and a thickness that was frightening. Balls hanging and everything. They spared no expense; they bought the best one, so she could feel every centimeter without hurting her cunt. They left with the bag hidden away, but their minds were already racing toward what would happen at home.

***

Before leaving for work, Rubén set the box on the bed, imposing with its size and that finish that inevitably recalled Dani’s cock.

—Today you have a sacred mission —he told her, winking—. I want you to take it all the way in. That cunt of yours to open up and swallow it up to the balls. And I want a photo as proof that that animal has entered your body.

Carmen, sitting on the edge of the bed, let out a nervous laugh while glancing at the toy.

—You’re crazy! I don’t know if I’ll be able to… it’s too much! It’s going to wreck me.

He laughed and, just before closing the door, added in a mocking tone:

—Check your phone in a minute. I’m sending you a visual aid.

A few seconds later, the phone vibrated on the nightstand. It was once again the photo of her brother’s huge cock. Carmen let out a choked cry and then a hysterical laugh.

—Do you really want me to do it with that cock in my head? —she texted back, dying of embarrassment but with her pulse racing and her cunt already starting to wet.

—I’ve known you for nearly thirty years —he replied instantly—. I know damn well that seeing that cock is going to get you so horny the toy will go in on its own. Enjoy your little brother’s silicone cock.

She was alone, looking alternately at the screen and the piece lying beside her. Her heart beat hard as filth and curiosity began to beat her shyness completely.

She undressed slowly, standing before the mirror, seeing herself reflected: her big tits hanging with desirable weight, the nipples already hard as stones, the soft belly, the shaved pubis and the cunt lips swollen, wet, shining with her own lubrication. She slipped two fingers between the folds and confirmed she was soaked just from thinking about it.

She lay on the bed, spread her legs, and looked again at the photo on the screen. Dani’s cock, hanging thick and heavy under the shower water. Her little brother. A jolt of guilty pleasure shook her whole body. She picked up the toy, still cold, and began rubbing it over her clit, drawing slow circles, while with her other hand she squeezed one breast and tugged at her nipple.

—Fuck… —she whispered to herself—. I’m so filthy.

She licked the silicone glans, imagining it was his, sucking it hungrily, covering it in saliva. She ran down the veiny shaft, put the fake balls in her mouth, one at a time, as she had seen done in videos. When the cock was soaked with spit, she brought it back to her cunt.

***

Rubén’s phone vibrated at the office, and the image left him breathless. Carmen, from the dimness of the bedroom, had captured a scene drenched in filth: reclined, with her thighs open in the effortless way that only comes from years of trust, her pale skin framing the dark, enormous toy resting on the swollen, soaked lips of her cunt.

The afternoon light emphasized the blush of her cleavage, and one breast spilled over the lace of her lingerie, her nipple stiff.

—Look what you’ve done… I can’t believe this cock will fit in my cunt —she wrote under the photo.

—You’re gorgeous, slut —he replied, his heart racing—. Don’t pressure yourself. Spit on your clit, soak it well with spit and your juices, and let it go in little by little. That cunt was made to swallow cock; you’ll see it surrender.

Carmen put the phone aside. She looked again at the real image and then at the toy. The suggestion was so strong that the fear of size was beginning to turn into a physical need to feel full, to feel wrecked, opened by that monstrous cock.

She did what he told her. She brought two fingers to her mouth, wetted them well, and ran them over her clit, drawing faster and faster circles. With her other hand she grabbed the toy and began rubbing her lips with the glans, soaking it in her own slick, which was already running down to her asshole. She pushed slowly, feeling the crown of the glans forcing its way in, stretching the entrance of her cunt in a way she had never felt before. It burned, it hurt, but it was a delicious pain that made her moan to herself in bed.

—Ah, fuck, fuck… —she moaned, biting her lip—. It won’t fit, it won’t fit…

But it did fit. Little by little. With her mouth open and her eyes closed, she felt the whole glans disappear inside her, and the walls of her cunt closing around that thick head. She stayed still, panting, letting herself adjust.

***

The phone vibrated again with an insistence that nearly knocked it off the table. Carmen had left behind any trace of shyness. In the new photo, her thighs strained as they opened the way for the toy, which was already sinking a third of the way into her swollen, gleaming cunt. You could see the lips stretching around the shaft, whitened by tension.

Along with the photo came a voice note, a broken whisper between moans:

—You have no idea how turned on I am looking at this cock… my brother’s… I feel like I’m going to tear my cunt, but I’m so soaked the toy wants to go in on its own. I’ve got it halfway in already, love. I’m embarrassed to say it, but imagining whose cock this is has me totally out of control. I’m doing things I never thought I’d do… I’m sucking my fingers full of my juices, I’m pinching my nipples until it hurts…

Rubén, breathing hard in the middle of the office, had to go into the bathroom. He locked himself in a stall, unzipped, and pulled out his cock, already rock hard and dripping. He started jerking off while listening to the voice note over and over, imagining his wife, always so modest, impaling herself on that monstrous cock while thinking of her own brother’s.

***

The video he received afterward was the culmination of so many years of complicity. The image was crystal clear: Carmen reclined, her body trembling in a way he had never seen, tits bare and bouncing slightly, and her cunt opened impossibly wide around the toy.

With one hand she held the phone showing the photo of her brother; with the other she guided the silicone cock, pumping it in short thrusts, pulling it out glossy with slick and driving it back in. Guttural moans escaped her, mouth open, eyes half-closed. The tension was unbearable, her thighs trembling in spasms. Suddenly her body arched with animal force and a gush of wetness shook her, spraying liquid around the toy under pressure, soaking the sheets in the first squirt orgasm of her life.

—Ah, fuck! Fuck, fuck! —she screamed, unable to keep quiet, her cunt convulsing around the silicone.

Still panting, she did not stop. Taking advantage of that abundant lubrication and the filth of the forbidden image, she began pushing the toy inward with both hands. Rubén watched, hypnotized, with his own cock in hand, as the piece disappeared centimeter by centimeter. Carmen’s cunt lips stretched obscenely, whitish, swallowing inch after inch of that monstrous cock while she let out a deep moan, half effort and half release.

The toy went all the way in. Clear down to the silicone balls resting against her ass. Carmen stayed still for a second, eyes wide, feeling the cock reach a depth no one had ever touched before. Then she started moving, rocking her hips, pulling it out to the glans and shoving it back in, fucking herself with a shamelessness that left her husband cumming in the office bathroom stall, splattering the door.

Carmen looked at the camera with misty eyes and a smile of absolute satisfaction, the toy still buried in her cunt, proving that her mature woman’s body was capable of swallowing such a cock.

—Look, love… it all went in. I took it all the way to the balls. I feel so full I can barely breathe. Come soon and pull it out with your mouth —said the message accompanying the video—. I want you to lick up the last drop that’s leaking out of me.

Rubén, his pulse racing and his mind locked on the image of his wife impaled, cleaned himself as best he could and gathered his things. He couldn’t wait another second.

***

The impact had been so devastating that he came without being able to stop it, barely touching his cock. With a smile of defeat and pleasure, he took a photo of the evidence of his involuntary climax: his hand full of thick semen, the bathroom floor splattered.

—Look what you did to me. I came in the office bathroom just from seeing you. My hand’s full of cum because of you —he texted.

Carmen, from the bed, still with the toy inside her, let out a triumphant laugh when she saw the photo of her husband defeated by his own excitement.

—Come over and bring it to me hot —she replied—. This cunt wants real cock now.

But then the phone rang in a different way. It wasn’t a message; it was a call. It was Dani.

—Hey, sorry to bother you at work —the boy said, his voice somewhat flat—. I’m a bit down in the dumps over some girl trouble. Want to shoot some pool this afternoon, just the two of us?

Rubén looked at the photo on the screen and then at his wife’s message. The filth closed the circle perfectly. The owner of that cock that had turned their marriage upside down wanted to meet him alone.

—Of course, kid —he replied—. Swing by the house in an hour and we’ll go.

When Dani arrived, Carmen was already dressed, hiding beneath her clothes the secret of that afternoon: the soaked panties, the cunt still throbbing and slightly swollen, the marks of her own fingers on her nipples. Rubén greeted him with a paternal hug, but as he looked at him he could not stop thinking about the cock the boy was carrying and how his wife had imitated it hours earlier until she came in streams.

—Behave yourselves —she said with a modest, angelic smile, seeing them off at the door, squeezing her thighs discreetly because just looking at him made everything between them wet again.

The two men walked off toward the bar, leaving her alone with her fantasies and the toy still warm on the bed, while Rubén prepared to spend the afternoon with the owner of the cock that had changed their marriage forever.
