My Son-in-Law Desired Me When My Daughter Went Away on a Trip

I had spent half my life teaching at a secondary school on the outskirts of Valencia and, although at fifty-five I was beginning to dream of retirement, I couldn’t deny that I still loved what I did. The greatest privilege of my profession had always been the long summers, that dead time that was now, without my knowing it, going to change me more than I could have imagined.

My daughter Lucía, thirty-one, was also a teacher. In her first year she met Adrián, another teacher a couple of years older than her, and before long they married. From that marriage came Hugo, my seven-year-old grandson, for whom I felt pure devotion, and he for me.

I always made a point of not meddling in their life as a couple. I was only ever willing to lend a hand and look after Hugo when they went out, together or separately, because they were fairly liberal people. Before summer, Lucía suggested a trip with her friends and didn’t want to leave Adrián alone in charge of the boy, because he was studying for a competitive exam for a post in the education inspectorate.

—Would you mind coming to stay at the house those days? Hugo will be at camp almost all day, he won’t be any trouble.

—So when I finally get a break from your father, you dump your son on me — I protested, laughing.

Andrés, my husband, went away every summer for a few days to walk part of the Camino de Santiago, so in any case I was going to be alone at home.

—It’s only ten days, Mom. Hugo is at camp from nine to five and Adrián won’t lift his head from his notes. You’ll have the pool all to yourself.

I couldn’t say no. I packed a suitcase, left Andrés some food made in advance, and installed myself at their villa in the development, twenty minutes from the city, in a quiet area of tree-lined streets and neighbors who greeted one another over the hedges.

***

I arrived just in time to take the boy to camp, at a nearby sports center. Adrián had already dressed him and given him breakfast.

—Thanks for staying, mother-in-law. I’ll try not to get in the way — he said at the door.

—Don’t worry and focus on your own thing. Hugo and I get on wonderfully.

The boy was five steps ahead of me, with that energy I don’t know where they get at that age. He gave me a quick kiss at the door and shot off toward the others, as if I’d already stopped existing.

The next day I said goodbye to Andrés, who was leaving for a week to walk from Burgos. He asked for a black coffee, looked me up and down, and tossed it at me, as if offering a deal rather than seeking my company:

—What if you came with me? Walking would do you good.

—I don’t want to spoil your adventure. You enjoy it more on your own — I replied, without emotion.

He nodded with a tired smile, kissed my cheek, and left. I took it for granted, as so many times before, that mine was the lot of being accompanied and feeling alone at the same time.

***

I decided to invent a routine: reading, walking for an hour a day, recovering a bit of myself. I put on a pair of shorts and a fitted T-shirt to go out, and crossed paths with Adrián in the hallway.

—I didn’t know you went for walks. I should; all these hours in a chair are making me stiff.

—If you join me, I warn you I keep a good pace — I told him.

We walked together, and the truth was I liked not doing it alone in a place I didn’t know. We talked about Hugo, about Lucía, about the exam to which he was giving body and soul.

—You’ve made a beautiful family — I told him.

—Your husband doesn’t think much of me — he smiled.

—Don’t hold it against him. You took his darling away. No man would have seemed good enough for her.

—Well, he doesn’t deserve you either. It must be something in the family.

I gave him a light slap, laughing, but the compliment left a strange warmth in my chest.

When we got back, I went to the bathroom for a towel and found him there, drying off after his shower, completely naked in front of the mirror. It had been a very long time since I’d seen a young body like that, and I’m not going to lie: it shocked me. The broad shoulders, the flat, worked stomach, the dark, dense pubic hair, and hanging heavy between his thighs, a thick cock even at rest, with the big glans still half-covered by the foreskin. I stood motionless, unable to look away, my mouth dry and my heart hammering against my ribs. I watched him run the towel over his balls, saw him hold them without shame to dry his groin, and felt my cunt clench all at once, with a warm wetness that surprised me.

—Sorry! I thought you were using the other bathroom — I stammered.

—My fault. I prefer the shower stall. From now on I’ll leave this one for you.

I closed the door and, under the water, I frightened myself. He’s your daughter’s husband, Carmen. Behave. But the image of that cock swinging back and forth wouldn’t go away, and before I knew it I found myself rubbing my nipples under the stream, imagining the weight of that shaft in my hand.

***

That night I couldn’t sleep. I got up for some water and, as I passed down the hallway, heard an unmistakable sound in his bedroom: the wet smack of a hand sliding up and down a well-lubed cock, and ragged breathing. I knew I had no right, and yet I crept closer, nerves on edge. The door was slightly ajar.

He was naked on the bed, legs apart and knees bent, his cock erect between his fingers, shining with spit or lubricant. He was working it slowly, his wrist turning over the tip, his thumb stroking the frenulum before sliding back down to the root. It was huge, thicker than hard, and the veins stood out all along the shaft. With his other hand he was squeezing his balls, rolling them between his fingers like someone judging fruit. Seeing him like that left my mouth dry and my panties soaking in two seconds.

I went back to my room and locked the door behind me, as if afraid of something. I couldn’t sleep. I couldn’t remember the last time Andrés had come near me, and yet my son-in-law’s life didn’t even need my daughter’s presence. Suddenly, from his room, a long, rough gasp came, and then a tight grunt clenched between his teeth that said everything: he had come, and I could almost imagine the hot spurts falling onto his stomach.

I lay down on the sheet, took off my T-shirt and, slowly, fighting a small war between desire and duty, pulled my panties down to my ankles and kicked them to the floor. I started with my breasts, trapping my nipples between index finger and thumb, tugging until the tips hardened and a jolt went straight down to my cunt. I licked my fingers and brought them below. I was drenched, soaked, my lips swollen and throbbing. I slid my middle finger between them and found the clit hard as a pea. I started rubbing it in slow, tight circles, while with the other hand I shoved two fingers deep into my cunt.

I imagined him coming through the door and looking at me. I imagined that thick cock slamming into me in one thrust, opening me, pushing all the way to my cervix. Would you like to see me enjoy myself? Would you like to shove it in balls-deep? I fucked myself with my fingers faster and faster, splashing in my own wetness, and with the other hand I kept tormenting my clit. I felt the current rise from my legs, tighten my belly, and I came with a muffled cry I had to bite into the pillow, thinking of the cock I had seen working itself one hallway away, of a tongue that wasn’t mine licking me whole.

The next morning I could barely exchange a word with him out of sheer shame.

***

The following days I spent discovering that he existed. Hugo’s counselor, an athletic, dark-skinned boy named Dani, was stunned when I told him I wasn’t the boy’s mother, but his grandmother.

—The grandmother? You really break the mold — he blurted out.

And Adrián, of course. Every time we crossed paths he looked at me in a way no man had used on me for years. One afternoon he came down to the pool when he was supposed to be studying.

—Done with the notes? — I asked.

—I looked out the window and saw a woman who distracted me — he said, looking me in the eyes.

—How silly of me. I don’t think a guy like you would lose concentration over a woman in her fifties.

—Don’t sell yourself short. At your age you have nothing to envy in your daughter.

I didn’t know what to answer. I went home with my pulse racing and the dangerous feeling of being alive again.

***

The second night it all happened again: the noise in his room, my body awake, my hands searching for themselves in the dark. This time I didn’t even last five minutes: the moment I heard the first wet smack down the hallway, I already had two fingers buried to the knuckles, and I was fucking myself imagining it was him. I imagined it better than the first time, that thick cock with the shiny head, I imagined him taking me from behind while he pulled my hair. I came twice in a row, clenching my clit as if I meant to tear it out.

When I caught my breath, I saw a thread of light in the hallway. He was there, in the doorway, watching me. He saw my legs open, saw my hand still inside my cunt, saw my naked tits beneath the fallen sheet. He left before I could say anything, but as he withdrew I noticed the hard, unmistakable bulge marking the front of his pajama pants.

In the morning I expected a reproach, but he gave me an affectionate good-morning kiss and, while making coffee, talked about it with a naturalness that disarmed me.

—Sorry about last night. I heard noise and thought you might need something. Masturbating is the most normal thing in the world when you don’t have your partner nearby. I do it too.

—I’m ashamed — I confessed.

—You shouldn’t be. You’re alone, your husband is far away in every sense, and summer has awakened you. It makes sense — he said, and then, more softly: — I’m curious. Who do you think about when you play with that cunt?

—You don’t ask that — I cut him off, red to the ears.

—I’ll tell you mine: I think about the bathroom scene. About you not stopping in the doorway, about you coming in, getting on your knees, and taking my cock into your mouth all the way down.

I stopped breathing. No one had ever spoken to me like that, and least of all in a kitchen, with coffee steaming between us.

—That fantasy is dangerous, Adrián. I’m your wife’s mother.

I didn’t get any further; Hugo came in asking us to tie his shoelaces. We both bent down at the same time and his fingers brushed mine. It was the slightest contact, but it shot through me completely, and he noticed.

***

Another afternoon, during one of his breaks, he sat down beside me with two coffees and let his knee touch mine.

—We need to normalize what’s happening — I told him.

—Normalize it? That would mean being able to masturbate together — he said, laughing, winking at me—. Me with my cock in my hand, you with two fingers in your little cunt. Looking at each other.

And then he told me something my daughter had never dared confess: that they had an arrangement. Not an excuse to cheat on each other, but mutual permission for an occasional fling without reproaches, as long as nobody fell in love.

—The premise is that we love each other — he explained. — One night with another person isn’t going to change that. A good fuck doesn’t break a marriage.

I listened, fascinated. What if I also had the right to something like that? What if I also had the right to get properly fucked for once? Though Andrés would never understand it.

***

Friday was parents’ day at camp. Hugo insisted so much that I went, wearing shorts and a cap I’d stolen from my daughter. I spent the morning between sack races and painting workshops, feeling, to my surprise, like just another mother among many much younger than me. One of them suggested a dinner that night with the children and I happily signed up.

When we got back home, Hugo told his father about the dinner and Adrián didn’t miss the opportunity.

—Can I come? I need to socialize a bit.

—You need to study — I protested, even though inside I wanted him to come.

The boy ended the argument with a shout of joy and I had no way out. I tried on clothes in my daughter’s dressing room, which was more or less my size, until I found a dark blue wrap dress. I looked at myself in the mirror and, for the first time in a long while, I liked what I saw.

—You’re very pretty, Grandma — Hugo said when he saw me.

—Well — Adrián murmured, coming close to my ear — you smell so good.

The heat rose up my neck as I drove to the restaurant.

***

Dinner was a whirlwind of laughter and conversation among young people. He was attentive all night, passing me water, napkins, whispering things the other mothers couldn’t hear.

—That dress suits you better than your daughter — he told me softly. — Though I imagine it even better on the floor.

—The credit goes to the dress.

—The credit goes to the tits underneath. Afterward we could go have a drink. I need to get out.

—You’re crazy. And besides, we can’t leave Hugo alone — I replied nervously.

—That can be fixed.

And fixed it was. Before we said goodbye, the parents of Marcos, Hugo’s best friend, suggested that my grandson stay the night with them: they had a pool and video games. The boy was jumping with happiness. Only later did I connect the dots: it had been Adrián who orchestrated it, offering them his console account with the new game that had just come out.

I went out alone to the parking lot. He was waiting by the car.

—So what about that drink? You don’t have to look after anyone now.

I felt something like vertigo. Not because I didn’t want to, but because I wanted it too much. If it was true that my daughter was enjoying her freedom somewhere, what did I owe a husband who was five hundred kilometers away?

—You’re the devil — I smiled. — All right, but just one.

***

He drove to the city center and stopped at a lively terrace full of people much younger than me. We ordered two drinks. I still felt out of place.

—Doesn’t it seem strange to you? Being here with your mother-in-law.

—Forget age — he said, his eyes fixed on mine. — I always liked you, but this week I’ve discovered another woman. There’s chemistry between us, even if you don’t want to admit it.

I knew very well there was. He took me dancing on an improvised dance floor and, amid all those people, I stopped hearing the voice of my conscience. Every time he came close to speak over the music, I thought he was going to kiss me, but he didn’t. He wasn’t in a hurry, and that made me hotter. When we danced pressed together I felt his hard cock against my belly, a thick, insistent bulge that searched for me through the fabric of the dress. He moved on purpose, pressing into me, as if to remind me what he had there.

When he finally leaned in again, I looked at him, saw his lit eyes, and it was I who erased the distance. We kissed with a passion I had almost forgotten existed. His tongue entered my mouth and sought mine hungrily, and I bit it, sucked it, as if the mouth were only the rehearsal for other things. He cornered me against the wall by the bathrooms, sliding his hand over my breasts, squeezing them through the dress, pinching my nipples through the fabric until they hardened. His other hand hiked up the hem of my dress and stroked the inside of my thigh, slowly sliding higher until he brushed over my panties. He felt that I was soaking wet, and smiled against my mouth.

—You’re dripping, mother-in-law. I want to take you home. I want to eat that wet cunt of yours until you beg me to stop.

A voice inside me held me back. I asked to go home. Before getting into the car he kissed me again, with a sincerity that made me doubt my own refusal. If he fucks like he kisses, I’m missing out on something huge.

***

I asked for the keys to drive, because he had drunk more. Once on the road, I heard the click of his belt coming undone and felt him lean toward me.

—Adrián, stop… — I whispered when his fingers slipped under the dress.

—You just keep driving — he answered softly. — If I’m not going to take you to bed, at least let me play a little with this beautiful cunt.

I tried to pull away, but my body didn’t cooperate. He lifted the hem of my dress to my waist, moved my soaked panties aside, and his fingers sank straight between my parted lips. I moaned. He found my clit at once and began tracing slow, precise circles, tighter and tighter, while I barely kept the car at sixty kilometers an hour. With two fingers he opened me, slid into my cunt all the way, felt how swollen and hot I was inside, and started pumping me without pause while his thumb kept tormenting my clit.

—You’re soaked, fuck. This little cunt hasn’t had a proper fuck in years, has it? — he murmured.

I couldn’t even answer. He leaned all the way over, lowered himself from the seat, and buried his face between my thighs. His mouth replaced his fingers and his tongue moved over me slowly, bottom to top, like someone savoring dessert. He licked my lips one by one, slipped his tongue into my cunt, and then moved up to trap my clit between his lips and suck it hard, not letting go. I gripped the steering wheel until my knuckles went white, biting my lip so I wouldn’t close my eyes.

—Do you like it? — he asked, lifting his head for a second, his chin shining.

I didn’t want to answer, but when I felt he might pull away I put my hand on the back of his neck and drew him back, pressing his face against my cunt. There was no point pretending anymore.

—I love it. Suck this cunt, don’t stop — I admitted with a moan.

As we entered the development I turned off onto a dark, landscaped area, killed the engine, pushed the seat back, and opened myself entirely to him, with my legs draped over the headrests. He settled between my thighs as if he had spent his whole life waiting for that place. His tongue was now precise torture: long, broad licks that covered the whole cunt and ended in a pull over the clit. He slid in two fingers and curved the tips searching for that spot inside, the one nobody had found for years, while continuing to suck me without a break. He found the exact place, pressed and pumped while his tongue danced over my clit, and I exploded in an orgasm that had been waiting for me for years, soaking his whole chin, bucking against his mouth, with a long cry that sounded ridiculous inside the car.

—We haven’t completely lost the night — he said, smiling over my belly, licking his lips. — You taste fucking delicious, mother-in-law.

***

We went into the house in silence, nerves beating like background music. When I closed the door and turned around, he caressed my face with the back of his hand, then with his lips. A touch, a promise. I let him kiss me as if I were twenty, but with the experience of my fifty-five years. I could feel his hard cock pressed against my hip, thick, demanding, and I no longer had either the desire or the strength to stop him.

—Don’t rush — I asked, leading him to the bedroom. — I want it to last all night.

I unbuttoned his shirt one button at a time, kissed his chest, the line of hair that ran down to his navel, and knelt in front of him to wrestle with his belt. When I yanked down his trousers and underwear in one pull, his cock sprang out and hit my cheek, and I was almost tempted to laugh from the shock. It was even more impressive up close: long, thick, with the glans purple and throbbing, already with a fat drop of precome shining at the tip. I cleaned it with my tongue, tasting that salty flavor, and he let out a guttural moan.

—Fuck, Carmen…

I took it fully in my hand, feeling the weight and the pulse of the veins, and took it into my mouth without hesitation, as far as I could. It barely fit. It choked me in the throat, forced my jaw wide open, but I didn’t want to let it go. I started sucking with all my might, up and down, soaking it in saliva, circling my tongue around the glans each time I came back up. With my other hand I stroked his balls, weighed them, massaged them slowly while I kept on eating his cock. He grabbed the back of my neck and began to set the pace, pushing a little deeper each time, until I felt the head thump against the back of my throat.

—That’s it, suck that cock. Swallow it all — he panted.

My eyes were watering, my mouth filling with spit that ran in thick strings over my breasts, but I didn’t want to stop. Never in my life had I sucked cock with such hunger. I pulled it out for a moment, ran it over my face, used it on my lips, my cheeks, my nipples, and then took it back down my throat again.

When I felt him close I let go, stood up, and yanked my dress off. No bra, no panties: I wanted him to see me all at once. I lay down and let him go over me. He licked my nipples one by one, bit them carefully, licked my belly, and in an instant his fingers were back below, searching for me. I was so wet his fingers slid into me without resistance. He started fucking me with his hand while he kept on eating my tits, and without warning he ripped another orgasm from me that caught me off guard, so close to the first that I ended up trembling and laughing at the same time.

—Let’s see how you fuck — I teased him, lying on my back and opening my legs all the way. — Come and fill this cunt for me.

I shouldn’t have said it. He climbed over me, grabbed his cock and slid it once between my lips, soaking it in my wetness, and then, without measuring, he pushed in all at once until he buried it completely inside me. I felt a roughness, the sting of flesh that wasn’t used to so much, but pleasure erased it in two thrusts. I felt him pull it out to the tip and shove it back in to the balls, felt his groin collide with mine with a wet, dull sound, felt my walls open to make room for that cock filling me completely.

—That’s it, fuck me hard. Fuck me like I haven’t been fucked in years.

He propped himself on his arms and sped up. The thrusts were hard, dry, each one shaking my whole body and making my tits bounce. One of his hands kneaded my breast, twisting my nipple until I cried out; the other went down and found my clit between our bodies, and began rubbing it with two fingers in time with his thrusts. I dug my nails into his shoulders, his back, bit his neck, sucked it, kept begging in his ear for more.

—Harder, give it all to me, don’t stop…

He put my legs over his shoulders and drove into me even deeper, so deep I felt the head striking me very far inside, in a place that hurt and felt good in equal measure. In that position I came again, shaking, clenching his cock with spasms he could barely withstand. Without pulling out he rolled me onto my side, lifted one leg, and kept fucking me from that angle, and I came again, chaining orgasms as if a gate had broken open inside me.

He got me on all fours and positioned himself behind me. He grabbed his cock and rubbed it over my cunt, over my perineum, then plunged it in again in one stroke. Now the thrusts were savage: he gripped my hips with both hands and pulled me back each time he pushed forward, and the sound of his balls slapping against my clit filled the whole room. He slapped one cheek, then the other, and a cry escaped me that sounded like a plea.

—Give me more, give it all to me, come inside…

He grabbed my hair, yanked me back and drove into me three, four more times, with all his strength. When I heard him say my name, his body jerked and I felt the hot spurts shooting inside me, filling me, overflowing me. He stayed pressed against me for a while, his cock still inside, throbbing, while I trembled with a final orgasm that slipped in among the others.

—I’ve never come so many times — I panted, collapsing onto the tangled sheets.

When he finally pulled out, I felt the thick semen running down my thighs and took my fingers down there, curious. I was overflowing. I licked my fingers without thinking, and when he saw me, he groaned again.

***

We slept embraced under the breeze from the window and I woke alone, with a moment of fear that he had gone, repentant. But he came out of the bathroom with a towel around his waist and wet hair, smiling.

—Good morning, mother-in-law. How did you sleep?

—Wonderful — I replied, with irony. — The relaxant you gave me last night left me brand new.

He laughed and kissed me again, and from a kiss we moved to hands, and from hands back to desire. I pulled at his towel and there it was again, his cock, already half hard, hanging heavy between his thighs. I took it into my mouth, still from the bed, and brought it awake with licks, sucking the head, running my tongue under the glans until it hardened completely. He laid me on my back, positioned himself between my legs, and slid into me again, firmer than ever, with all the calm of morning. He fucked differently than the night before: slower, deeper, savoring it. Each thrust went all the way in and stayed there for a second, grinding me from the inside before coming out. I let myself be carried by a vertigo I no longer wanted to come down from.

Without stopping his movement, he took his fingers to his mouth, coated them well in spit, and lowered his hand between my buttocks. He slid one finger lower, toward a forbidden place, and began to stroke my little hole with the pad of his finger, circling it slowly, pressing just a little. My back arched on its own. When the finger worked its way in to the knuckle, while his cock kept pounding my cunt, I almost lost my mind from the pleasure.

—You’ve got a beautiful place here — he murmured, moving his finger slowly inside me. — It’s so tight. Nobody’s ever touched it properly, have they?

I felt so unchained that I decided to break with my entire past. I had never allowed Andrés to do it, even though he had asked me once or twice. But Adrián’s firmness was unlike anything I remembered. I got onto all fours against the headboard and pushed my hips back, offering myself completely. I spread my buttocks with my hands so he could see well what I was giving him.

—Do you want to try it? Put it in there.

—Yes — he answered, surprised, his voice hoarse.

—Bring the cream from the bathroom.

He came back with a jar, coated his cock well until it shone, and spread me too, slowly. He lubed his fingers and prepared me carefully: first one, moving it in circles, opening me from within; then two, curving them, pushing them all the way in while with the other hand he rubbed my clit to keep me on edge. I was wary, because I had always heard the first time hurt, but when I finally felt the head press at the entrance, he did it so slowly, so controlled, that there was barely any sting.

—Relax, mother-in-law, breathe — he murmured, pressing a little more.

The ring gave way and I felt the glans enter, wide, taut, and behind it came the rest: centimeter by centimeter, holding back so as not to hurt me, until I felt his hips pressed against my buttocks. He was entirely inside me, in a place where no one had ever been before, and the sensation of being full from behind left me speechless.

—How does it feel? — he asked, still, his hand stroking my back.

—Very aroused — I confessed, letting myself be penetrated for the first time in my life. — Move. Fuck me there, don’t stop.

He began to move, first carefully, pulling out until just the crown and pushing back in slowly, and then more eagerly, gripping my waist, setting a steady rhythm. I learned on the fly to relax as he entered and tighten as he withdrew. Each thrust tore a new moan from me. With one hand he reached forward to my cunt and slipped in two fingers, fucking both my holes at once, and that was when I could no longer hold back: I began to come without stopping, in waves that shook me, clenching his ass so hard with the spasms that he let out a roar and lost control.

—I can’t anymore, fuck…

His thrusts became erratic, savage, he grabbed my hips with both hands and rammed me four more times, all the way in. With one final push I felt him finish inside me, filling me there too, and that sensation of strange warmth in a new place dragged me into a brutal orgasm that left my arms limp.

He collapsed beside me, panting like an animal, and I curled against his chest. He stroked my hair and kissed my forehead.

—Thank you, mother-in-law. Your wife has never let me do that.

—Nor have I let Andrés — I laughed. — It was my first time. And it won’t be the last.

***

We stayed wrapped in each other, sweaty and satisfied, looking at one another without promises or false hopes.

—You need to study a bit — I told him, because responsible Carmen was still inside me. — I’d never forgive myself if you failed because of me.

—All right. But I want to fuck you again before you go pick up Hugo.

I wasn’t able to refuse. I headed to the bathroom with a new urgency under my skin, knowing we still had five days of secret encounters ahead of us, of nights of skin and confidences, of tender and wild sex, of cocks and cunts and mouths and asses. It wasn’t love, not the kind lovers feel, but it was undeniable affection. I didn’t know what would happen afterward; I only knew that, during those days, Adrián belonged to me, and I intended to enjoy him to the very last breath.
