They Thought Their Little Brother Was Gay

Carla and Mariela were the pride and the headache of the house. Carla, the older one, was tall, with a mane of brown hair that always smelled of expensive shampoo; she had a smile that could be sweet or sharp depending on the day. Mariela, the younger one, was more curvy, with copper-highlighted hair and an energy that never let her sit still for a second. They shared everything: clothes, secrets, and an absolute conviction about their brother.

Tomás, whom they had called Tomi when they were little, had always been categorized. Quiet, skinny, he preferred the computer and books to anything else. They’d never known him to have a girlfriend, he spoke softly, and according to his sisters’ infallible diagnosis, his gestures were “too delicate.” For them the conclusion was crystal clear, and they repeated it with laughter in the next room.

“Tomi’s a fag,” they said, like they were commenting on the weather.

That certainty became, without them fully planning it, the basis of a dangerous game. Since they believed their brother had absolutely no interest in their bodies, they grew careless. Or rather, deliberately provocative. With their parents working late, the house was theirs and Tomás’s, and that was all the permission they needed.

***

It started subtly. They’d come out of the shower and cross the hallway wrapped in tiny towels, pretending to fumble with them right in front of Tomás’s half-open bedroom door.

“Tomi, close the door, we’re coming through!” Mariela would shout, while her towel slipped a little more than it should, revealing the curve of her ass or the beginning of a breast, the nipple still hard from the cold water.

He, from his desk, would murmur an “sorry” and keep his eyes glued to the screen.

Then they escalated. They would change in the living room under the excuse that their bedroom was a mess. Carla would stand in front of the big mirror in lace underwear, spin around, and ask her brother, who was trying to watch TV:

“Does this set make me look fat, Tomi?”

He’d shake his head quickly, eyes fixed on the screen, but his ears would be tomato red. They chalked it up to his usual embarrassment.

The big leap came with the underwear. After a hot day, Mariela, instead of throwing it in the hamper, let a used pair of panties fall “by accident” onto the arm of the couch where Tomás was sitting. The fabric still had the damp mark of her crotch, and the smell of a sweaty girl hit him straight in the nose.

“Oops, sorry, Tomi,” she said without an ounce of remorse, picking them up slowly and brushing his forearm with her fingers.

He went stiff as a board. From then on it became a habit. They’d leave pieces of clothing on his bed, on the back of his chair, once even inside the empty mug he had on his desk.

“So you’ll wash your plate, lazy ass,” Carla said with a little laugh.

They expected disgust, total discomfort. But Tomás would only stay quiet, serious-faced, and get rid of the garment without saying a word. What they didn’t know was that as soon as he closed the door, he’d bring those panties to his face, breathe in his sisters’ cunt smell, and jerk off until he came in ropes against his stomach, imagining how he was fucking them both.

***

Over time they stopped settling for provoking him from afar. They treated him openly like a doll with no desires of his own, someone they could use as a prop with no consequences. And that made them crueler.

It started on the sofa. Mariela, in tiny shorts, would throw herself on top of him, pretending they were little kids wrestling. Her sweaty body pressed against Tomás’s, high-pitched laughter, hands trying to tickle him. But soon she stopped pretending and sat directly on his lap, grinding against him under the excuse that he “didn’t even notice.” The crack of her ass, barely covered by the shorts, pressed right above his zipper.

“Look, Tomi, you’re not even flinching,” she’d say, moving in slow circles. “You’re a log. Do you like your little sister’s perfume or does it do nothing for you, little faggot? Don’t you like how your sister’s cunt smells when she’s sweating?”

He’d stay motionless, but his fists would clamp down on the edge of the sofa until his knuckles turned white. Under his pants, his cock would swell painfully against the zipper, and Mariela, even if she wouldn’t have admitted it in front of a mirror, felt that hard bulge rising beneath her ass and kept moving a little more.

Carla was no slouch. She’d walk behind his desk chair, lean down, and massage his shoulders hard, letting her loose breasts under her baggy T-shirt brush against the back of his neck. Her nipples, hardened by the friction, left two clear points through the cotton, and she’d lower them right beside his ear so he could feel them well.

“Your neck is so tense, Tomi. If you were a real man you’d have already turned around to look at my tits. But since you’re the way you are, this doesn’t even turn you on, does it?”

One afternoon Carla climbed barefoot onto the arm of the sofa and rested a foot on his lap, playing.

“Massage it, little brother. I’ve been in sandals all day.”

He obeyed in silence, his fingers firm on the top of his sister’s foot, jaw clenched. Mariela, sitting on top of him, burst out laughing.

“Look at what we’ve got him doing, Carla. Our Tomi is the best piece of furniture in the house. He probably doesn’t even notice us.”

The details they were missing were still there, more intense every day: the clenched fist, the held breath, the dark gleam in his eyes when he thought no one was looking, fixed on the curve of a hip or the mocking mouth of Carla. It was no longer just repressed desire. It was patient rage, a pressure building under constant humiliation. A bomb his sisters kept bringing the fuse closer to, convinced it would never blow.

***

A stifling Saturday came. Their parents went to a family gathering far away and wouldn’t be back until dawn. Carla and Mariela decided to cool off in the backyard pool. Tomás stayed in his room, as always. They, believing themselves the absolute owners of the house and of the “truth” about him, raised the stakes. They came in dripping wet, not drying off, in tiny bikinis, droplets running down their skin, the fabric stuck to their bodies, outlining their nipples and the line of their sex.

“Tomi! Aren’t you hot? Get out of that cave!” Mariela shouted, pushing the door open.

He was sitting on the bed with a book, posture rigid, a pillow over his lap.

“I’m fine,” he said, his voice lower than usual.

“Look how you’re sweating,” Mariela said, shamelessly approaching, sitting on the edge of the bed and putting a hand to his forehead. “You’re burning up, Tomi.”

Her chest, barely covered by the triangle of her bikini top, was inches from his face. Carla came in behind her.

“Yeah, you’re always locked up in here. You look like a vampire.”

Tomás didn’t answer. He just stared, jaw tight, breathing through his nose. Mariela, still playing, ran a hand through his hair.

“Poor little brother, all heated up by summer.”

Then Carla made the fatal mistake. Following the game of touching and provoking, she slid her hand from his neck to his chest “to check his heartbeat.” And as she did, with her forearm she pushed the pillow aside.

What was exposed left no room for doubt. His shorts were stretched in a way impossible to ignore, clearly showing the size and hardness of a cock that was anything but delicate. You could even see the swollen head pushing against the fabric, and a dark stain of pre-cum at the tip.

The silence turned thick, electric. Mariela’s mocking smile froze. Carla’s hand stayed in the air. Tomás slowly lifted his gaze. There was no shyness left. His dark eyes, loaded with an intensity they had never seen in him, swept over them from top to bottom, almost naked, wet, and suddenly vulnerable.

“Fag, you said?” he asked, in a low, rough voice that raised goosebumps on their skin. “You think this cock belongs to a fag?”

Neither of them could speak. The game was over. All at once they understood they hadn’t been provoking an harmless brother. For weeks they’d been lighting the fuse on a bomb.

***

Tomás didn’t wait. With a speed that startled them, he grabbed Carla by the wrist, still hovering near his chest. The force made her gasp.

“You girls like touching so much,” he said, pulling her in. “You like showing your ass and tits all over the house so much.”

Carla fell seated beside him and felt the hardness pressing against her hip through the fabric. A shiver of fear and something much less decent ran down her back. Her brother’s cock was huge, much bigger and thicker than she could ever have imagined, and it throbbed against her skin like a trapped animal.

Mariela tried to back away, but he stretched out the other arm and caught her by the waist.

“Where do you think you’re going? You were the one playing the most. The one who sat on top of me thinking I couldn’t feel it when all you were doing was rubbing your ass on my cock.”

“We were wrong, Tomi…” Carla stammered.

“Of course you were wrong,” he cut in. He let go of her wrist and put a hand on her naked thigh, slowly moving up toward the edge of her bikini bottom. “But now you’re going to fix it. Both of you.”

“Stop! We’re your sisters!” Mariela blurted out.

Tomás looked at her with cold calm.

“And did that matter to you when you were grinding on me? No. Because to you I didn’t count as a man. I was furniture. Well, now the furniture is going to show you otherwise, and he’s going to fuck you both until you can’t walk.”

The hand that had been stroking Carla’s thigh slipped under the bikini fabric. Tomás’s fingers found his older sister’s soaked cunt, dripping, with the damp hairs stuck to her skin. She stifled a cry that turned into a moan when he parted her lips with two fingers and ran his thumb over her swollen clit. The humiliation of weeks, the built-up tension, had left her like that without even her understanding it fully.

“Look at this,” Tomás said, looking at Mariela while his fingers played between his older sister’s folds and buried themselves one, two, three knuckles deep. “So much mocking and the slut is wetter than the pool. Listen to how it sounds.”

The splashing of his fingers going in and out of Carla’s cunt filled the room. She moaned, ashamed, but her hips moved on their own, seeking those fingers, choreographing the motion, impaling herself on the rhythm her brother imposed. Mariela watched him with parted lips and something ignited in her gut, forbidden and electric. Without realizing it, she pressed her thighs together too.

“You, Mariela,” he ordered, without stopping fingering Carla. “Lock the door. And come back here.”

Hypnotized, she obeyed. When she returned, Tomás nodded at her bikini top with his chin.

“Take it off. All of it. I want to see you naked.”

With trembling hands, Mariela undid the ties. The top fell away, leaving her breasts bare, round, with brown nipples standing up like stones. Then the little bikini bottoms slid down her hips and exposed a neatly shaved cunt, with a narrow strip of hair on the pubis and the lips already swollen and shiny.

“Good,” he approved. “Now kneel. And show me your tongue.”

While he kept his fingers inside Carla, who was already pushing her hips against his hand and panting open-legged on the bed, Mariela knelt between her brother’s legs. Tomás yanked his shorts down in one motion and his cock sprang out, thick, hard, veined, the head purple from holding it in. A thread of pre-cum hung from the tip. The last remnant of his sisters’ theory shattered right there.

“Suck it,” he ordered. “Down to the base. And if you choke, you’ll take it.”

Without needing to be told twice, Mariela lowered her head, stuck out her tongue, and licked the entire shaft from the balls to the tip, gathering the sticky thread. Then she took it into her mouth and started sucking, first fearfully and then hungrily, using both hands, pulling her hair back so he could see how his little sister was swallowing his cock. Tomás let out a deep, satisfied growl and planted a hand on the back of her neck to push her deeper.

“That’s it, slut. Quite different from what you imagined, huh? Suck it good, because this log is yours from today on.”

Carla came under his fingers. A violent climax shook her: the walls of her cunt clenched around her brother’s hand, her body arched against the mattress, and a hot gush of fluid soaked his wrist and ran down his forearm. She screamed, not caring about anything, biting her lip until it hurt, while Mariela kept sucking him on her knees, eyes wet and a strand of spit hanging from her chin.

***

What followed that afternoon was nothing like anything they had imagined. Tomás used them in turns and together, changing positions and roles, directing everything with a confidence they had never seen in him.

After Carla came, he grabbed her hair and put her beside Mariela, both of them kneeling in front of him on the rug.

“Now both of you. Take turns. And whoever isn’t sucking licks my balls.”

The sisters looked at each other for a second, blushing, and obeyed. Mariela kept sucking the tip while Carla licked his sack, sucking one and then the other. Tomás watched them from above with a master’s calm, guiding their heads with both hands, switching his cock from one mouth to the other.

“Look at the sisters taking turns sucking the fag’s cock. Do you realize how good you are at it?”

Then he made them stand. He bent Carla over the desk, face down, ass up. With one tug he ripped off her bikini bottom and threw it to Mariela.

“Smell it. And don’t let go.”

Mariela buried her nose in the soaked fabric of her sister’s cunt while Tomás positioned himself behind Carla, spread her cheeks open with both hands, and rested the head of his cock between her dripping lips. He thrust into her in one shot, all the way to the hilt, and Carla let out a howl that bounced off the walls.

“Oh, Tomi, fuck! You’re splitting me open!”

“Take it, bitch, we’re just getting started.”

He started fucking her with long, deep strokes, gripping her by the waist, making her slam against the desk with every thrust. Carla’s ass jolted against his pelvis with a wet, heavy sound, slap, slap, slap, and the papers on the desk flew everywhere. He grabbed her hair at the nape and yanked her back to arch her spine, driving deeper still. Mariela, with the panties pressed to her face, shoved a hand between her legs and started touching herself, unable to take it, watching her brother tear her sister’s cunt apart.

“You, Mariela,” he said without stopping, “get on the desk. Open your legs and put your cunt in your sister’s mouth.”

Mariela climbed up, sat on the papers, and spread her thighs right in front of Carla’s face. Tomás grabbed the older one’s head and pushed it against her sister’s sex.

“Eat it. Eat your little sister’s cunt the same way you eat your own when you think about me.”

Carla, with Tomás’s cock hammering her cunt from behind, stuck out her tongue and started licking Mariela, who immediately squirmed and began moaning, clutching her sister’s hair. The image was brutal: the two sisters linked by the mouth, and him behind, fucking one while making them eat each other.

“That’s it, little sluts. I want you nice and close. Nice and sisterly.”

He switched holes without warning. He pulled his dripping cock out of Carla and shoved it into Mariela’s mouth, so she could taste her sister’s cunt. Mariela sucked desperately, and he took the opportunity to throw Carla onto the bed, turn her on her back, and lift her legs to her shoulders. He drove into her again, this time face to face, looking her in the eyes while he split her cunt apart.

“Tell me I’m the man of the house. Tell me you’re your brother’s slut.”

“Yes, Tomi, yes… you’re the man… I’m your slut, my brother’s slut… keep going, don’t stop, fuck me harder,” Carla panted, her tits bouncing with every thrust, her nails digging into his back.

While he fucked Carla, he motioned to Mariela to sit on the older sister’s face. The two sisters ended up stacked like that: Carla underneath, fucked and eating cunt; Mariela on top, riding Carla’s mouth and kissing Tomás over her. The three bodies moved to the same rhythm, sweaty, the room thick with the smell of sex, cunt, and cum.

After a while, Tomás pulled his soaked cock out of Carla, stood on the bed, and grabbed himself while the two sisters knelt before him again, this time cheek to cheek, looking up with mouths open and tongues out, the way they had seen it done. He came with a deep roar, long thick ropes of semen that fell across both faces, on Mariela’s forehead, in Carla’s mouth, on their breasts, hanging in strings between their lips.

“Swallow it. All of it. And then pass it mouth to mouth. I want to see.”

Carla and Mariela, without hesitation, joined their tongues and passed the cum from one mouth to the other in a deep, dirty kiss while Tomás watched from above, his cock still hard and dripping semen on them.

Afternoon turned to night. When Tomás finally collapsed onto the bed, exhausted, his sisters stayed beside him, their bodies shining with sweat, the air heavy with the smell of sex and something none of the three would ever be able to name out loud. Their tits and cheeks were marked with dry semen stains, their cunts swollen and red, their throats raw from all the sucking and moaning.

“Still think I’m gay?” he asked, one hand resting on each of their stomachs, his fingers idly playing with the pubic hairs.

They shook their heads, too weak to speak. There was no mockery left in their eyes. There was respect, a little fear, and a dangerous attraction to the power their brother had just shown.

“Good,” Tomás said, closing his eyes. “From now on, when you show yourselves, when you touch me, when you spread your legs, it’ll be because I say so. Understood?”

A whispered yes, doubled, was all the answer he got.

***

The following week was a whirlwind of secrets. At first dazed, Carla and Mariela quickly discovered that the forbidden was hotter than any guilt. With their parents always absent, the house became the stage for a new routine.

Tomás no longer hid. He gave orders with a calm that made them tremble. The first rule was to dress the way he wanted when the three of them were alone: in a thong and no bra, or completely naked, depending on his mood. At first they protested with nervous little laughs, but one dark look silenced them and they obeyed.

One afternoon he called them into the living room and made them kneel in front of the sofa, on all fours, ass up and face to the floor. He sat down, unzipped his pants, and pulled out the cock that was already hard from just seeing them humiliated.

“Come here. Both of you. Work my cock.”

Carla and Mariela crawled over, hurried, jostling each other without really fighting to get there first. They took turns with mouth and hands: while one had him all the way down her throat, the other licked his balls or sucked his perineum. Then they switched without being told, already coordinated, as if they had always done this.

“Who’s in charge here?” he asked, grabbing their hair in turns and forcing himself down their throats until they choked and their eyes filled with tears.

“You, Tomás,” they answered in chorus, voices hoarse, saliva hanging, cum already dripping down their chins.

“And what are you?”

“Your sluts. Our brother’s sluts.”

“Louder.”

“Our brother’s sluts!” the two shouted, and he came all over both faces at once, marking them again.

Verbal humiliation put them on edge as much as the sex itself. They liked being put in their place, being forced to admit out loud how far they’d gone because they’d gotten turned on by their own brother. Afterward he made them eat each other out, or fuck one while the other watched and touched herself, or fuck them both one after the other without pulling out, passing his cock from one cunt to the other until the three of them collapsed on the rug, wrecked and happy.

***

The double life began the next day, at the family dinner. Carla and Mariela sat across from each other, an acted-out normality. Their parents talked about work, about bills. Tomás ate quietly. But under the table he slid a foot first to one thigh, then to the other, stroking them over their pants until he found their pubis and pressed there firmly. Both of them tensed, exchanged a quick look of complicity, and lowered their eyes to hide their smiles, feeling their panties grow wet right there at the table, in front of their parents.

Outside, everything stayed the same: three ordinary siblings, one more family. Inside, behind the closed door, a secret none of the three intended to give up. The one they had spent years treating like furniture had become the center of everything, and the fuse they themselves had lit was never going to go out.
