The Summer My Sister-in-Law Started Looking at Me Differently

The country house had belonged to Javier’s parents for decades, and that July weekend it smelled of lavender and dry earth. Marcos arrived Friday afternoon with Lucía on the motorcycle, without warning, as was his custom. His brother and sister-in-law were already settled in, and Sofía came out to greet them with a rehearsed smile that cooled for barely a second when she saw Lucía climb down from the back seat, take off her helmet with her hair tousled and her eyes bright, and bring her lips to Marcos’s cheek with the natural ease of someone who had nothing to prove.

Saturday dawned with that white heat that flattened time and erased intentions. Javier received a call before breakfast and appeared in the kitchen buttoning his shirt with an annoyed expression.

—I have to go into town. There’s a problem with the inheritance papers that can’t wait —he said, kissing Sofía on the forehead without looking at her—. I’ll be back at noon.

No one protested. Sofía prepared coffee in silence while Lucía peeled an orange, leaning against the counter. Marcos watched them both from the table, with that calm attentiveness that sometimes made people uncomfortable if they did not know him well. The sound of Javier’s car faded along the road, and the house fell silent.

***

By eleven they were already beside the pool. Sofía chose the one-piece swimsuit that always made her feel more secure, navy blue with a gold detail at the neckline, and stretched out on the lounger wearing enormous sunglasses and holding a novel she never opened. Lucía rubbed sunscreen onto her shoulders and lay down in silence, without ceremony or artifice. Her body was the result of months of training: firm, unadorned, needing no approval.

From his lounger, Marcos followed the thread of the conversation without participating much. Sofía talked about travel, restaurants in the city, the latest exhibition she had visited. She spoke well, with the precision of someone who knew her words carried weight. But every time she looked to Marcos for approval, he turned his gaze toward Lucía.

With a barely perceptible gesture, Marcos indicated something to her. Lucía understood without a word: she lifted herself slightly and untied the top of her bikini, letting it fall beside the lounger. Sofía saw her from behind her sunglasses and said nothing. Her small, firm breasts seemed to shrink a little further beneath the one-piece.

—Aren’t you going to join in? —Marcos asked, looking at Sofía with half a smile.

She forced out a brief laugh and lowered the straps of her swimsuit over her shoulders, leaving her torso bare with a gesture that tried to appear natural. It wasn’t. Sofía had the body that constant exercise had given her: symmetrical, firm, with nothing to hide. But beside Lucía, the comparison was merciless, not so much because of anything physical as because of the other woman’s indifference, the way she moved as though the sun and the looks simply belonged to her. Marcos joked under his breath and Lucía laughed, and Sofía did too, although her smile concealed something that was not laughter at all.

The afternoon stretched on languidly. For Lucía, lying there beneath the sun was simply a matter of naturalness: she moved with confidence, secure in her body and in Marcos’s gaze, which occasionally traveled over her with quiet possessiveness. Sofía, on the other hand, felt trapped in a contradiction. She had given in to something she had not wanted to give in to, and that surrender brought her no peace, only an irritation she could not name.

***

Lucía went inside to get some cold water, and Sofía seized the moment. She approached Marcos from behind, her torso still bare and damp with sunscreen, and wrapped her arms around his shoulders.

—Marcos… —she murmured, her voice lower than usual.

He did not pull away. He held her by the waist with firm hands, and when she lifted her face, seeking something she did not quite know how to ask for, he inclined his head and let his lips brush hers. It was brief, wet, without urgency, but unmistakable. Marcos’s tongue pushed between Sofía’s lips for barely a second, just long enough for her to taste him, and one of his hands slid down from her waist to squeeze one of her buttocks over the swimsuit fabric. Sofía let out a tiny, involuntary gasp and felt her pussy grow wet at once, with that instant, treacherous reaction she had not experienced with Javier in months.

—There will be a time —he said quietly before letting her go—. I’m going to fuck you until you don’t remember your name. But not now.

Sofía swallowed. She felt her nipple throbbing against the swimsuit, still half-lowered, and a warm trickle running down the inside of her thigh. The word fuck echoed in her head like a promise and a threat at the same time.

The sound of Lucía’s footsteps in the hallway separated them with the speed of the guilty. Sofía returned to her lounger with her heart racing and a mixture of relief, anger, and something darker she preferred not to examine too closely.

***

Javier arrived at noon, tired, with papers under his arm and hungry. Dinner was peaceful, with local wine and a conversation that rolled along on its own without anyone having to push it. Later, while the men argued over what to put on television, the women cleared the kitchen.

Sofía washed the dishes with the mechanical efficiency of someone who needed to keep her hands busy so she would not think. Lucía dried them in silence, wearing a calm expression that, for reasons Sofía could not quite explain, seemed almost insulting. When they returned to the living room, Lucía lasted twenty minutes of the movie before standing up.

—I’m going to bed —she said, kissing Marcos on the temple—. Don’t be long.

Javier and Marcos continued watching the movie. Sofía stayed too, crossing her legs with deliberate indifference, although her attention was entirely fixed on her brother-in-law’s profile. When the credits ended, everyone went to their rooms without further ceremony.

***

Marcos pushed open the guest-room door without making a sound. Lucía was sleeping on her side, one arm extended toward the empty side of the bed. He watched her for a moment from the doorway, with that calm that was not indifference but a particular form of attention.

He lifted the sheet, stroked her back with his palm, and before she had fully awakened, delivered a sharp smack to her buttocks. The slap of palm against flesh echoed dully through the room. The pink mark appeared instantly on the white skin of Lucía’s ass.

Lucía opened her eyes sleepily and protested with a murmur.

—Let me sleep a little longer…

—You have an assignment first —he said, in a voice that allowed no argument but was not cruel either—. You have to earn your sleep by sucking my cock.

She sighed, recognizing the tone, and slowly sat up. Marcos smacked her again, then once more, firm and calculated, each one louder than the last, until Lucía’s buttocks bore the clear shape of his hand. Then he positioned her as he wanted: lying on her back with her head hanging over the edge of the bed, her throat completely stretched, completely exposed. It was a position Lucía knew well, one that always left her in that particular state of vulnerability he deliberately sought.

He rewarded her with slow caresses before moving closer. His hands traveled over her body with that mixture of possession and care that she recognized as exclusively his: he pinched her nipples until they hardened, moved down over her flat belly, and opened her thighs to run two fingers over her pussy, already wet from the ritual itself, from knowing she was about to serve him. When he lowered his underwear and pulled out his cock, hard and thick, he let it fall against Lucía’s face and ran the glans over her closed lips, coating them with a glossy layer of pre-cum.

—Open —he ordered.

Lucía parted her lips and stuck out her tongue. She began at the bottom, calmly, like someone who knew the ritual by heart: she licked his balls one by one, took them carefully into her mouth, ran the tip of her tongue up the swollen vein along the underside of his cock, and when she reached the glans, wrapped her lips around it and lowered herself slowly, swallowing whatever she could in that inverted position that left her throat like a straight channel.

Marcos took hold of her breast while she worked, squeezing with a firmness that bordered on pain. She protested with a muffled moan, moving her hands compulsively toward his.

—Does it hurt? —he asked, his tone somewhere between curiosity and satisfaction.

—Yes —she answered, barely audible with his cock moving in and out of her mouth.

—A little more —he said, squeezing without adding cruelty but without relenting, until Lucía’s eyes filled with tears.

When he decided it was enough, he gave her full access. Lucía opened her mouth as wide as she could, and Marcos began fucking her throat with rhythmic thrusts, holding her head with both hands. His balls struck her nose with every push. She controlled her gagging with months of practice, swallowing saliva and the pre-cum gathering in her mouth, letting him use her throat the way a pussy is used. Every so often Marcos buried himself to the hilt and stayed there for several seconds, feeling her neck bulge from within around the shape of his cock, before pulling it all the way out to let her breathe. A thick strand of saliva hung from Lucía’s chin down to her tits.

—Good girl —he murmured, running his thumb over her swollen lip—. That’s it.

***

Lucía’s period prevented her from offering herself in the usual way, and that circumstance was a redirection they both understood without needing to negotiate it. Marcos placed her on the floor with a cushion beneath her head and shoulders, her legs folded upward until her knees nearly touched her ears, her body’s weight resting on her neck and her ass pointing directly at him. It was an uncomfortable position that left her asshole completely exposed. She knew it, and so did he.

Marcos crouched and spat on her hole twice, spreading the saliva with his thumb and pushing the tip inside to prepare her. Lucía clenched her teeth when she felt the finger forcing its way in. He added more saliva, then lubricant from a bottle he had brought, and began stretching her with one finger, then two, slowly twisting them until her sphincter yielded enough.

—Breathe —he said.

When he pressed the tip of his cock against her ass and began to push, Lucía’s eyes begged him for more time, but Marcos did not relent. The way was difficult at first, marked by the resistance of her body: the thick glans struggled against the tight ring until he managed to pass through it, and Lucía bit her lips to keep from making too much noise in that house with its thin walls. A muffled moan escaped her anyway when he gained a few more inches. Little by little, he advanced patiently, moving in and out with short strokes, taking ground with every thrust, until he buried himself to the base and felt her surrender beneath his control, her ass throbbing around his cock and her belly trembling. Then he pulled all the way out in one motion, leaving Lucía’s anus open for a second before it closed, and drove back in with one abrupt, final movement.

Lucía lost control. Her hands struck his thighs instinctively, trying to stop something that could no longer be stopped, and the sound that came from her throat threatened to travel through the whole house. Marcos pulled her panties from the floor with one hand without stopping his thrusts and calmly, almost tenderly, stuffed the fabric into her mouth. The gesture was practical, and she was grateful: it helped her contain what she could not contain on her own.

—Very good. Look at me —he said softly when he felt her calm down.

She fixed her eyes on his and did not look away again. Marcos began fucking her in earnest, with long, deep thrusts that shook her entire body. The wet sound of his cock entering and leaving her ass mingled with her moans muffled by the fabric. He held her behind the knees to keep her folded, and she felt Marcos’s entire weight bearing down on her belly every time he buried himself to the base. The position was brutal, and the lack of air was beginning to make her dizzy, but precisely that combination of suffocation, pain, and humiliation was what dissolved her from within.

Marcos quickened his pace when he felt himself getting close. He pulled his cock from her ass, knelt over her, and came in jets over Lucía’s tits and neck, three, four, five thick spurts that stained her skin and reached her chin. A thread of semen slipped into her mouth at the edge of the panties, and she swallowed it without thinking.

When he finished, he did not move away immediately. He held her, kissing her with the taste of his own cum on his lips, nibbling her stained breasts with the firmness she liked, until he drew moans from her that mingled pain with something much harder to name. His fingers moved down between her legs and, avoiding her bloodied pussy, focused on her swollen clitoris. He rubbed it with two fingers, fast and precise, while his other hand squeezed her neck without cutting off her air. Lucía arched on the floor as orgasm surged through her like an electric shock, trembling from head to toe, her ass still contracting around the emptiness Marcos had left behind.

Exhausted and trembling, she remained silent for a moment, semen drying on her skin and that strange peace settling over her, the only peace she found in this place and in this role. Being Marcos’s toy was, in its own way, a fulfillment nothing else in her life could equal.

***

In the master suite, the night had a different rhythm.

Javier drew her toward the bed without much preliminary conversation. Sofía let him, although her mind was still at the pool, on the brief kiss beside the lounger that afternoon, on Marcos’s voice telling her I’m going to fuck you until you don’t remember your name before letting her go. Her husband’s body over hers was familiar and comfortable, and that irritated her in a way she did not know how to articulate. Javier pulled down her panties and slipped two fingers into her pussy with his usual gesture, checking whether she was ready, and was surprised to find her soaked. He did not know that the wetness was not for him.

He parted her thighs, settled between them, and penetrated her in one thrust. Sofía closed her eyes and let herself be fucked, allowing her husband’s cock to move in and out of her with the rhythm she knew by heart. She was so wet from the memory of Marcos that Javier came within two minutes and had to stop himself, pulling away and breathing through his nose.

When he tried to move toward something she never quite accepted—he ran his thumb over her asshole, pressing with the clear intention of putting it inside—her body tensed involuntarily. He grunted through his teeth, frustrated, and roughly placed her on her knees on the bed, her face against the pillow and her ass raised. At first Sofía remained rigid when Javier’s cock entered her pussy from behind again. But her husband’s body, his steady thrusting against her buttocks, drew moans from her that escaped on their own, small and uncontrollable, and something inside her began to loosen. She imagined Marcos was the one holding her like this, that Marcos was the one gripping her hips and penetrating her to the hilt, and suddenly her pussy clenched around her husband’s cock with a new force.

At the most unexpected moment, she took the initiative: she turned, pushed him backward, and settled on top of him, guiding his cock into her pussy with her hand before dropping down and impaling herself fully. She set the rhythm. Javier looked up at her with surprise and approval. He brought his hands hungrily to her breasts.

—They drive me crazy —he murmured, firmly pinching her nipples—. They’ve always driven me wild.

—Look at them moving while I ride you —she said, in a voice she did not recognize as her own—. Look at me putting it inside me.

That particular gesture, that attention to the part of her body she had felt at a disadvantage beside the pool hours earlier, freed her from something she had been carrying since the afternoon. Sofía closed her eyes, and for the first time all day, forgot Marcos, Lucía, the comparisons, and the humiliations. She rode hard, rising and falling on Javier’s cock, feeling the glans brush a spot inside her that drove her wild. When orgasm swept through her from one end to the other, a muffled cry escaped her, smothered against her husband’s shoulder, and her pussy squeezed his cock in long spasms, one after another.

Afterward, she was the one who took the initiative to give him something in return. She slid down Javier’s body and took his cock, wet with her own juices, in her hand, licking it from base to tip before taking it all the way into her mouth. She sucked slowly, playing her tongue around the glans, pulling it out completely to spit on it and then taking it back in, masturbating him with her hand at the same time. Javier watched her tenderly, with a trace of amazement, stroking her hair and sinking his fingers into the nape of her neck without forcing her.

—Let me know —she murmured mischievously, her lips shining, and he gave a brief, muffled laugh.

When the moment came, she pulled his cock from her mouth and held it pointed toward herself, and he filled her tits with cum in two thick spurts that spilled down her cleavage to her belly. Sofía rubbed the semen into her skin with her hand, mixing it with sweat, in a blend of intimacy and play that had more to do with complicity than overflowing passion. Then they rested, breathing at the same rhythm, side by side.

Javier fell asleep immediately, his body heavy and his expression satisfied. Sofía, however, remained awake, her eyes fixed on the ceiling, her husband’s semen still drying between her breasts and her pussy throbbing for other reasons, trapped in a tangle of thoughts that would not let her rest. On the one hand, the humiliation beside the pool had kindled a forbidden desire in her that she dared not confess: she wanted him precisely because he had made her feel small, and she could not stop imagining Marcos’s cock opening her pussy with the same violence with which he had opened Lucía’s mouth behind the wall. On the other, Javier’s hands had reminded her that she was still desired, that her body could be celebrated without mockery or comparison. The contrast disarmed her. Only when exhaustion overcame her did she surrender to a light, turbulent sleep, filled with confused images in which the two men blurred together and she could no longer tell whose cock was penetrating her in each scene.

***

Lucía got up silently when Marcos fell asleep and went to the bathroom to clean herself. She sat on the bidet and carefully turned on the tap, letting warm water run between her legs to wash away the remaining lubricant and semen trickling down her ass and thighs.

Then she heard it: on the other side of the thin wall, the unmistakable murmur of someone else doing the same. She recognized Sofía’s restrained breathing, the brief, careful movements of someone trying not to make a sound, the stream of the bidet washing away another man’s semen. Lucía turned off the tap until only a thread of water remained and finished in silence, without giving herself away. She said nothing. She did nothing. She only knew that the other woman was there, on the other side of the wall, with a man’s cum running down her thighs just as it ran down Lucía’s, and that neither of them needed words to understand what it meant.

For a moment, the two women shared the same air, the same post-sex intimacy, separated by barely a few inches of plaster. The house fell silent after that, although the silence held different things behind each closed door.

***

The next morning, the motorcycle left before Javier and Sofía had finished their coffee. Lucía pressed herself against Marcos’s back as the road opened before them, wind in her face and the calm of someone who knew exactly where she belonged.

They stopped at a gas station halfway there. The girl serving at the counter was young, her hair pulled into a high bun, and she gave Marcos a direct smile that lingered a moment too long. Lucía noticed. She said nothing. That was part of the deal with a man like him: you could not control him, only choose whether to stay, and she had been choosing to stay for a long time.

Back beside the motorcycle, before starting it, Marcos took out his phone and checked his messages. There was one from Sofía, sent less than an hour earlier:

“I can still feel on my lips what happened beside the pool. And my pussy is still wet thinking about what you promised me. It shouldn’t have happened. Do it again.”

He smiled crookedly and put the phone away without replying. He started the motorcycle, and Lucía wrapped her arms around his waist without asking anything, unaware of reproaches or doubts, happy to be his while the engine purred and the afternoon stretched before them like limitless terrain.

***

In town, Javier carried the market bags beside Sofía. They were walking slowly down the main street when he spoke without looking at her, his voice grave and without direct accusation:

—Quite an intense way of saying goodbye to my brother this morning.

He said nothing else. He did not need to.

Sofía did not answer. She swallowed and kept walking, her eyes fixed on the sidewalk. Guilt weighed on her, but something else burned inside her too, something that was not entirely guilt: the memory of that very brief kiss beside the lounger, Marcos’s hand squeezing her ass beneath her swimsuit, his voice promising a moment that had not yet arrived, and the unsettling certainty that the story had not ended there. In fact, it had barely begun.

The silence between them was enough. Enough to know what neither of them yet dared say aloud.
