The Training That Changed Everything Between Father and Daughter

The house pool was silent except for the rhythmic splashing of water. It was five in the afternoon and the sun slanted across the patio, igniting the surface in bands of gold. Mariana cut through those bands with each stroke, long and precise, the body of someone who had spent half her life swimming and no longer thought about what she was doing.

At twenty-four, she moved through the water as if she had been born in it. The long muscles of her back tightened and released in a choreography only constant training could give. Her brown hair, tucked under her cap, had escaped in a strand that floated behind her like a wake.

Esteban watched her from the edge, seated on one of the loungers with a folded towel over his knees. He was still a strong man, broad-shouldered and big-handed, and for months he had begun to look at his daughter in a way he did not know how to name.

At first he had told himself it was pride. She swam well, she worked hard, and a father has the right to look with admiration at what he helped build. But admiration had slowly drifted somewhere else, to a dark place he did not dare put into words.

Mariana touched the wall and stopped, panting. She took off her goggles and searched for him with her eyes.

—What time did I make? —she asked, still breathing hard.

—I wasn’t with the stopwatch —he lied—. I was watching you.

She smiled, unaware of everything, and pushed herself out of the water. The swimsuit clung to her body, outlining every curve, the shape of her nipples hardened by the cold, the slit of her cunt perfectly drawn beneath the taut Lycra. Water ran down her shoulders, down the line of her back, down her legs. Esteban felt the blood rush to his cock, a thick hot throb that had been showing up for months every time he watched her come out of the water. He stood up with the towel open and held it out to her, making sure she did not see his pants.

—Here. You’ll get cold.

When she reached out, their fingers brushed. It was only a second, barely a touch of wet skin against dry skin, but Esteban felt something run up his arm like an electric current. Mariana didn’t seem to notice. She wrapped herself in the towel and sat on the edge of the lounger, wringing the water from her hair.

—You did really well today —he said, and his voice came out rougher than he expected—. Your technique is flawless.

—I work every day, Dad. —She looked up—. Are you okay? You have a weird face.

—I’m fine —he answered too quickly—. I’m just proud of you.

It wasn’t pride. It hadn’t been just pride for a long time. He wanted to fuck her. Plain and simple, like that, with the swimsuit still on.

That night, after dinner, Esteban stayed awake for a long time. He heard the shower water in Mariana’s room, the squeak of the old pipes, and imagined her lathering herself, her hands sliding over her tits, between her legs, the hot stream falling over her shaved cunt. He slipped his hand into his pants and gripped his hard, swollen cock, stroking it slowly, biting his lip so as not to make a sound. He came thinking about her, about his daughter’s mouth opening to take his dick down to the throat, and when his semen stained his belly he hated himself with a force that did not last five minutes. By morning the desire was still there, intact, waiting for him at the foot of the bed with his cock hard again.

During the following days, the workouts became a ritual charged with something neither of them named. Mariana had started noticing the intensity of her father’s stares. She wasn’t stupid. She felt those eyes pinned to her ass, her tits, the little triangle of fabric sticking to her between her legs every time she got out of the water. And instead of making her uncomfortable, her cunt would grow wet in a way that shamed her, a thick flow that mixed with the chlorine and ran down the insides of her thighs when she took off her swimsuit in the changing room.

She wondered how he would fuck her. What her father’s cock would be like, whether it would be thick, whether it would hurt, whether he would talk dirty in her ear. And she was frightened by the question itself while she sank two fingers beneath her panties.

***

It was a Thursday afternoon, with the patio empty and the whole house to themselves. Mariana finished her lap and touched the wall, and when she lifted her head she found her father standing there, right at the edge, waiting for her. This time he wasn’t carrying the towel.

—Get out —he said, in a low voice.

She pushed herself out and stood before him, dripping, her chest rising and falling from the effort. For an instant neither of them said anything. The only sound was water running off her body onto the hot tiles.

—Dad —she began, and didn’t know how to go on.

Esteban lifted a hand and moved the wet lock of hair away from her face. The gesture was slow, deliberate, and lingered longer than any paternal gesture should have lingered.

—I can’t stop thinking about you —he confessed—. About fucking you. About putting it in you. I know it’s wrong. I know everything that is wrong about this.

Mariana should have stepped back. Instead, she stayed still, feeling her pulse hammer in her throat and her cunt tightening beneath the swimsuit.

—I think about it too —she murmured, almost voiceless—. I touch myself thinking about you, Dad. Every night.

He lowered his head and kissed her. It was not a father’s kiss. It was a long, deep kiss, tongue sliding all the way in, seeking hers, biting her lower lip. Esteban’s hand went straight down her wet back and closed over one ass cheek, squeezing it over the swimsuit, sinking his fingers into the firm flesh of her ass. Mariana moaned into his mouth and pressed herself against him, and against her belly she felt the hard bulge of her father’s cock pushing through his pants.

—You’re hard —she whispered, surprised by her own words.

—For you. For months. Every day.

Right there, beside the pool, he pulled down the straps of her swimsuit and freed her tits into the afternoon air. He bent down and sucked one nipple, tugging it with his teeth, while his other hand slid under the fabric and found her wet cunt, wet not from water but from something else. He pushed two fingers in and she opened herself on her own, panting against his shoulder.

—Inside —he said against her mouth, his fingers still inside her—. Not here. Inside I’ll put it all the way in.

***

He half-carried her into the house, his cock outlined under his pants, her swimsuit pulled down to her waist and her tits bare. They crossed the living room without saying anything, breath coming in broken gasps, and in the hallway he pinned her to the wall again to suck her mouth and slide his hand back between her legs. Mariana fumbled for the zipper of his pants and pulled it down, and when she took out his cock and wrapped her hand around it she let out a gasp.

—God, Dad, your cock is so big.

—All for you.

The bedroom was dim, with the blinds half-drawn and the still air of the afternoon. He finished tearing the swimsuit off her in one yank, stripping her completely naked, and pushed her onto the bed on her back. He stood there for a moment looking at her, cock hard in his hand, running his eyes over her as if he wanted to memorize every inch: the round tits with their pink, stiff nipples, the flat swimmer’s belly, the shaved cunt with its lips already swollen and glossy with moisture.

—Spread yourself —he asked, his voice thick—. Show it to me properly.

She swallowed, bit her lip, and slowly parted her legs, letting him see everything. Esteban licked his lips.

—I’m not really sure what I’m supposed to do —she admitted, trembling.

—You don’t have to do anything. Let me do it.

He knelt at the foot of the bed, grabbed her thighs, and dragged her toward the edge. He put one leg over each shoulder and buried his face between her legs without ceremony. The first lick was long, from her asshole to her clit, and Mariana screamed and clutched the sheets. He pried her cunt lips open with his fingers and licked inside, searching for her clit with the tip of his tongue, sucking it, teasing it with his lips. He pushed in one finger, then two, curling them against the front wall, and kept sucking her clit while he finger-fucked her.

—Dad, Dad, don’t stop, don’t stop —she panted, moving her hips against his face, her hands locked in his gray hair.

He ate her for long minutes without mercy, until he felt her cunt tighten in pulses around his fingers and she came with a hoarse cry, her legs closing around his head, her whole body shaking on the mattress. Esteban pulled back, his face soaked and a dirty smile on his mouth, and wiped the back of his hand over his lips.

—You’ve got a sweet cunt, baby. Now you suck my dick for me.

Mariana, still trembling, let herself drop to her knees on the carpet while he sat on the edge of the bed. She took his cock with both hands and looked at it for a second, swollen, the head purple and a clear drop on the glans. She stuck out her tongue and licked it, shyly, and he growled.

—Put it all the way in. In your mouth. Don’t be afraid.

She opened her mouth and slowly took it in, awkwardly, until the tip touched the back of her throat and made her gag. She withdrew, took a breath, and went back down. Esteban placed a hand on her nape and guided her, setting the rhythm, fucking her mouth with slow thrusts at first and then faster, watching her tears spill and the saliva run down her chin and drip onto her tits.

—Like that, daughter, like that, suck my dick all the way —he panted—. You suck it so fucking well, you suck it so well.

When he felt he was about to come in her mouth, he pulled her away by the hair. His cock came out with a wet sound, gleaming with saliva, harder than before.

—Come here. On the bed. On your back.

***

She obeyed, lay down and spread her legs, and he positioned himself between them. He took his cock in his hand and ran the head along the lips of her cunt, rubbing it over her clit, teasing, until Mariana began to beg him.

—Put it in me already, Dad, please.

—Look at me —he asked—. I want you to look at me when I put it in.

She obeyed. And while he pushed, slowly, the cock opening her cunt centimeter by centimeter, she did not look away from his eyes for a single second. There was a moment of discomfort, the feeling of being stretched to the limit, and then her body yielded and she felt him slide all the way in, until her father’s balls hit her ass.

—Fuck, you’re so tight —he groaned through clenched teeth—. You’re choking my cock.

He started moving. At first with slow, deep thrusts, pulling almost all the way out and driving back in to the hilt, watching the slick cock go in and out of his daughter’s cunt. Mariana dug her nails into his back and wrapped her legs around his waist, pulling him in, asking with her body for faster, harder.

—More, Dad, harder, fuck me harder.

He growled and left behind the last shred of control. He grabbed her hips and started fucking her for real, with hard thrusts that made the bed creak and tore a gasp from her with every stroke. Mariana’s tits bounced with each impact, the sound of skin slapping against skin filled the room, and she started saying filthy things she didn’t even know she knew.

—Yes, like that, tear my cunt apart, Dad, it’s yours, your cunt, all yours.

He turned her over. He put her on all fours, ass lifted, and shoved it into her from behind again. He grabbed her hair with one hand, yanking her head back, and with the other gave her ass cheek a slap that left a red mark. Mariana screamed and pressed herself against him, pushing her ass back to receive every thrust.

—This is how I would’ve fucked you for months —he growled in her ear, never stopping—. Every time you came out of the pool with that swimsuit glued to your cunt. Every fucking night, daughter.

—And I let you look at me, Dad —she answered between gasps—. I tightened my swimsuit so you’d stare at me. Ah, ah, yes, like that, like that.

He grabbed her tits from behind, tugging on her nipples, and kept fucking her until he felt her cunt closing around his cock again, squeezing it, milking it. Mariana came with a muffled scream into the pillow, her whole body shaking, her ass pressed hard against his pelvis.

—I’m about to come —Esteban panted—. Where do you want me to put it?

—Inside —she moaned—. Inside, Dad, fill me up completely.

He gave two, three more thrusts, deep, savage, and came with a hoarse groan from the very bottom of him, emptying himself completely inside his daughter’s cunt. He felt his cock pounding out load after load, and he stayed there, buried to the hilt, until the last contraction gave way. Then he collapsed over her back, sweating, his heart racing.

When he pulled out, a thick ribbon of semen ran down Mariana’s inner thighs and stained the sheet. She turned slowly, legs still open, and smiled at him with her mouth still red from sucking him.

***

They stayed like that for a long time, intertwined, their skin wet with sweat and pool water, their breathing gradually finding calm. Esteban kissed her forehead, her temple, the corner of her lips, and ran a finger through her dripping cunt, gathering a little of his own semen and bringing it to her mouth so she could suck it. Mariana licked his finger without looking away.

—This should never have happened —he said, but there was no remorse in his voice, only the weight of what could not be undone.

—I know —she answered, resting against his chest, listening to the beating under his ear—. And still, I don’t regret it. Tomorrow you’ll put it in me again, Dad.

He held her tight against him and felt his cock start moving again. Outside, the sun kept sinking, and the pool, now still, returned the last orange glow of the afternoon. They both knew they had crossed a line they could no longer erase, one that would change forever the way they looked at each other at the table, in the hallway, in every workout to come.

But for that afternoon, at least, neither of them wanted to think about after. Only about the heat of the other body, the smell of sex filling the room, the father’s semen drying between the daughter’s legs, and the secret they would share from then on without ever saying it out loud.
