The Family Pact I Inherited on My Birthday

My grandfather Ernesto built up a business group that turns over figures I’d rather not write here. I won’t say the company’s name for obvious reasons, but suffice it to say that having the same surname as us opened doors in half the city.

My mother, Adriana, is his only daughter. When she finished university, she went to work in the group’s administration, which was what she had trained for, because since childhood everyone had taken it for granted that she would inherit the empire. She married my father, Daniel, whom she met at university, and he also ended up working in the company, under the direct orders of his wife, the boss’s daughter.

A year later I was born. And from my very first cry it was decided that I would be the next in line, in every sense.

My grandfather built two adjoining houses on a huge plot, with every imaginable comfort, one for my grandparents and one for my parents. He wanted the family to live together but independently, each couple under its own roof and all of them just a step away from one another. The property was registered in the group’s name, just like the cars my parents drove, so they didn’t have to pay a single expense.

All of this was explained to me in due course, and I received, as you can imagine, an education befitting my family’s standard of living.

But there was a hidden part. One I didn’t learn about until I turned eighteen, when my mother sat down in front of me and closed the study door.

—I knew that one day I’d have this conversation with you —she began—. What I’m going to tell you, I’m telling you because of an agreement your father and I made with your grandparents on the very day you were born.

The tone she used had already given me goose bumps.

She explained that everything I was about to hear was absolutely confidential. That under no circumstances could I repeat it to anyone, without facing the consequences that betraying that secret would have for me and for everyone. By then I was already frightened, so I promised her I would keep quiet, no matter what.

And then she told me everything, from beginning to end.

***

She started with the part that was hardest for me to digest: she had been fucking her own father, my grandfather Ernesto, since she reached the age of majority. In fact, he had been the first man to stick it in her, the one who had burst her virgin cunt. My grandmother had always known and had always been fine with it.

A month before getting married, my mother confessed it to Daniel so he’d know what he was getting into, and what he would gain if he accepted. My father spoke with my grandfather and the two men struck a pact: each of them could keep fucking the other man’s wife. My grandfather would keep his daughter’s cunt; my father would have access to my grandmother’s.

And then she reminded me of something I already knew, because it was public. My grandmother, when she was young, had won a beauty contest, and despite being close to fifty she was still a spectacular woman, with tits gravity itself didn’t dare touch. My mother admitted, half laughing, that she and I had inherited the same genes. That neither of us had entered a pageant, but that we wouldn’t have needed to.

—When I got pregnant with you —she went on, more seriously— I didn’t know which one of the two had knocked me up. In those months they fucked me almost every day, without condoms, always finishing inside, because I wanted to get pregnant. Some days I’d wake up with your grandfather’s semen dripping between my thighs and that same night your father would fill me over whatever was left. Neither of them ever pulled out before emptying me completely.

She paused to look at me. And then came the part that concerned me.

—When you were born a girl, everyone agreed to the same thing you’re hearing now. That on the day you came of age I’d tell you, and that if you gave your consent completely voluntarily, you would become part of the group as one more. With your father and with your grandfather, without distinction. And that, if you were still a virgin, it would be your father’s turn to be the first to burst your cunt, just as his father did with me.

No need to explain how I felt. A girl who had just turned eighteen hearing that from her own mother’s mouth, in the study of her house, on an ordinary afternoon.

My mother, already expecting the blow, gave me a few minutes to take it in and then told me I could ask her whatever I wanted.

***

The questions were piling up inside me, but the most urgent was the obvious one.

—And what exactly do I have to do?

—The only important thing —she answered— is that you agree to join voluntarily. With the same rights and the same obligations as everyone else. From that point on, your father and your grandfather could start fucking you as soon as you gave your consent.

I asked for time to think. She said that was fine, but that I couldn’t talk about it with anyone and that I had to make a decision that very night, because the next day we would continue talking.

And that was that.

I turned it over and over in my head. But I came to an uncomfortable conclusion: I had no choice but to accept. If I refused, living with them, knowing what I now knew, would become impossible. And there was the matter of the inheritance: I was the group’s natural successor, but that arrangement could be changed if I stepped away from what they expected of me.

Although, if I’m honest, what weighed most wasn’t the money. It was the thrill. Knowing that my mother had been fucked by her father for half her life. Knowing that my grandfather could be mine. And realizing that, whichever of the two was my biological father, by joining in I would end up with his cock inside me anyway.

I didn’t dislike the idea. Not at all. My cunt got wet just imagining it.

Because both Daniel and Ernesto were very attractive men. My grandfather, despite his age, was still in excellent shape from all the use he got out of the gym he had set up in the basement of his house, the same one we all used, and more than once, without meaning to, I had noticed the bulge in his shorts when he worked out.

So the next day, when we resumed the conversation, I told her yes. That I was in.

***

My mother asked me if I was still a virgin. She already knew damn well, but she wanted to be sure, because according to the agreement it was my father’s turn to be first. Before anything else, she took me to her gynecologist, who examined me and fitted me with a contraceptive implant in my arm, the same method she used herself, convenient and reliable for three years. The doctor said my hymen was slightly open, probably from the years of riding horses, and that my first time might be less painful than usual.

A week later, after my period was over and with the implant taking effect, we set the night. After dinner, my mother said goodbye to us, wished us a good time, and went off to my grandparents’ house, leaving us alone.

—Have fun —she said from the doorway, winking at me—. And you, sweetheart, let him do you. He knows exactly what he’s doing.

Daniel and I went upstairs to the bedroom. We both knew what we were there for, so there was no awkwardness or excuses. We undressed in silence, with that mix of nerves and desire that makes your hands shake a little. When I saw his cock, already hard just from looking at me, my mouth went dry. It was thick, with prominent veins and the head swollen and shiny, pointing upward as if it had been waiting for this moment for years. And it probably had.

—Come here —he murmured, sitting on the edge of the bed—. Let me have a proper look at you.

I came closer naked, my nipples already hard, and he ran his hands over me without rushing. He cupped my tits, weighed them in his hands, pinched my nipples until I let out a moan. Then he lowered one hand between my legs and slid his fingers through my cunt, which was already soaked.

—Fuck, daughter —he whispered—. You’re dripping.

He laid me on my back on the bed and knelt on the floor, spreading my thighs. He slipped his tongue between the lips of my cunt and started licking my clit with a slowness that made my back arch. He licked, sucked, thrust two fingers into me and curled them inside while he kept eating me out. I clutched the sheets and screamed, unable to control myself. In a few minutes he ripped the first orgasm of my life from me, one given by a man, and I felt his fingers tighten in rhythm with my contractions while he kept licking, swallowing everything that moistened his chin.

—Now you —he said, straightening up.

I knelt on the rug in front of him and took his cock in my hand. It was heavy, hot, and a bead of fluid gleamed at the tip. I brought it to my mouth not really knowing how to do it, letting myself go with what seemed to please him. At first just the head, sucking it like candy, running my tongue over the crown and the slit on top, tasting the salty fluid that leaked out. Then I went lower, taking him in until halfway down, until I started to choke and had to pull back coughing, strings of saliva hanging from my lips.

—Easy, my girl —he panted, grabbing my hair—. Tongue down below, like that… that’s it. Look at me while you suck me.

I obeyed, lifting my gaze and locking eyes with him while I sucked him off. I ran my tongue over the whole shaft, licked his balls one by one while I kept stroking him with my hand, and took him back into my mouth. To my surprise, it was turning me on more than anything else. I could feel my cunt throbbing, soaking my thighs, and I knew that if I kept sucking him for one more minute I’d come again without even touching myself.

—Are you ready? —he asked at last, gently pulling me away—. I don’t want to come in your mouth the first time. That will be another day.

—Yes, Dad. Mom already told me what the doctor said.

—I hope it doesn’t hurt —he murmured—. The important thing is that you have a good memory of tonight. If at any point you want me to stop, you tell me.

I lay back and he settled between my legs. He gripped his cock with his hand and ran it along the slit of my cunt from top to bottom, soaking the head in my juices, brushing my clit with the tip too. I lifted my hips toward him, unable to wait. Then he set it at the entrance and pushed slowly, almost fearfully, and I felt myself opening, felt him filling me centimeter by centimeter, felt a wave of heat run through my whole body. There was no pain. Only a sensation of being full, of belonging, that rose through my chest and left me breathless.

—It doesn’t hurt at all —I panted—. I like it. Put it all the way in, Dad.

—Then I’m going to go faster, my girl. Slowly at first.

He sank all the way in until I felt his balls against my ass, and he stayed inside for a second, letting me feel every beat of his cock. Then he started moving in a slow rhythm that gradually picked up pace, pulling nearly all the way out and slamming back in, and that drove me crazy right away. I wrapped my legs around his waist to hold him there, to keep him from ever slipping out. He grabbed my hips, drove into me harder, and my tits started bouncing with every thrust.

—Like that, Dad, like that, don’t stop —I moaned into his ear—. Fuck me harder.

—You’re so tight, fuck —he growled, sucking one of my nipples while he kept fucking me—. I’ve been waiting eighteen years for this cunt.

I didn’t take long to explode into an orgasm I couldn’t control; I heard myself moan as if I couldn’t get enough air, clinging to his arms, digging my nails into his back. My cunt closed around his cock in violent spasms that almost threw him out. Feeling my contractions, he sped up, and a little later he emptied himself inside me with a rough groan, pushing in to the hilt, stream after stream of hot semen flooding me from within.

Feeling his heat inside me ripped a second orgasm from me, chained to the first. My thighs were trembling, a thin thread of his cum mixed with my juices was leaking out of me, and he was still inside, moving slowly to squeeze out the last drop. We stayed still for a moment, sweaty, looking at each other as if we had just crossed a border with no way back.

We stayed like that for hours. He taught me positions I’d never even imagined. He got me on all fours and drove into me from behind, gripping my hair, making my back arch until I came again with his cock slamming inside me. He sat me on top of him astride and made me ride him, grabbing my tits while I went up and down at my own pace. He laid me on my side, lifted one leg, and took me again, more slowly, kissing my neck while he whispered dirty things in my ear. I liked them all, though deep down what I liked was having him inside me, feeling how he filled me, how he opened me. When he had no semen left and I had no strength left, we ended up asleep from sheer exhaustion, with his cock still inside me and his dried cum inside my thighs.

The next morning I told my mother everything, glowing, without leaving out a single detail. I was already a member of the group in every sense. She congratulated me and reminded me that I still had my grandfather to go, and that she hoped things would go just as well with him. She advised me to rest for a couple of days, because Ernesto was, in her words, “a real beast who fucks like a bull,” and it was best to arrive at that first date in top condition.

—And be careful —she warned me, laughing—. He’s got a bigger cock than your father. The first time he put it in me, girl, I thought he was splitting me in two. The next day I could barely sit down.

Three days later my grandmother came to our house and I went to dinner with my grandfather. There had always been a special complicity between us; I had always seen him as a kind of hero, and I suppose he had been looking at me differently for years, waiting for his moment.

That moment came that night. As soon as we finished dinner, we went upstairs to the bedroom.

—Lie down, sweetheart —he told me, taking off his shirt and revealing a torso more defined than I had ever imagined in a man his age—. I’ve wanted this for far too long.

He undressed me himself, unhurriedly, kissing every piece of skin he uncovered. When he finally took off his pants and I saw that my mother hadn’t exaggerated. He was longer than my father and quite a bit thicker, with two huge balls hanging underneath, and he was already pointing at me from the groin without even being touched.

He laid me on my back, spread my legs and buried his head between them. He started with his mouth, and he did it with such mastery that he gave me an orgasm within minutes. He licked me all over, from my asshole to my clit, lingering on the head until I howled, thrusting his tongue inside my cunt and moving it as if he were fucking me with it. When I came, he held my hips with both hands so I wouldn’t get away and kept eating me out until my legs were shaking.

Then he climbed onto the bed, made me kneel, and shoved his cock into my mouth without asking. He drove it all the way down my throat, until my eyes watered, and I choked on it but didn’t pull it out. He gripped my head with both hands and started fucking my mouth with short thrusts, whispering things that made my thighs clench.

—Look at you sucking it off, granddaughter. Just like your mother. Just like your grandmother. It’s yours, isn’t it?

—Yes, Grandpa —I managed to say, my voice broken, my chin covered in saliva—. Put it wherever you want.

He laid me on my back again, positioned himself over me and penetrated me while kissing me at the same time, letting me taste my own flavor on his tongue. The first thrust made me scream into his mouth; he was thicker than I was used to and stretched my cunt to the limit. But he fit inside quickly, and then he started fucking me for real. My mother had been right: he was tireless. He held me as if I weighed nothing, changed positions every little while, and lasted much longer than my father before finishing.

He put me on all fours and drove into me with a force that made his hips slam against my ass with a sound that was wet and dry at the same time. He stretched one cheek with his thumb, looked at my little hole and moistened it with his own saliva, warning me that that hole would be his too, though not that night yet. Then he put me on top of him and made me ride him while looking into my eyes, his hands squeezing my tits and pinching my nipples until I was panting. He finished by bending me over the edge of the bed, feet on the floor, fucking me from behind with long, deep thrusts while I clung to the sheets and asked for more.

He didn’t treat me like the spoiled granddaughter I had always been. He treated me like a female, like the dominant male he was, and I discovered that I liked being possessed that way more than I was willing to admit. When he had his way with me without mercy, I encouraged him in a low voice —“more, Grandpa, break me, fill me”— and that inflamed him even more, as if it reinforced some idea of possession he had over every woman in the family.

When he finally came, he did so with a roar that echoed through the bedroom, emptying himself inside me in spasms I could clearly feel against the walls of my cunt. He must have filled my entire womb, because when he withdrew slowly I felt a hot stream escaping me and dripping onto the sheets. Feeling his heat inside me, I couldn’t help thinking that with that same semen he had conceived my mother, and now I had it leaking between my thighs.

We didn’t stop there. He kept me awake until dawn, and by the time I fell asleep curled against his chest he had emptied himself inside my cunt three times and once in my mouth, forcing me to swallow every last drop. That early morning I finally understood what my mother had been trying to explain to me: in this family, sex was the true bond, without taboos and without impositions, each encounter agreed in advance by those taking part.

***

Over time I became the most in-demand, especially by my father, while my grandfather gradually refocused on his daughter without ever entirely leaving me aside. Once a month, almost always on Saturday night, the threesomes began, the two men with one of us in turn.

The first time I had both of them at once was something I can’t put into words. They started by undressing me together, each one with a tit in his mouth, while four hands roamed over my body leaving not a single inch untouched. I knelt on the floor and took both cocks into my mouth at the same time, sucking their heads alternately, switching from one to the other while they stroked my hair. Then my father lay on his back and I mounted him, his cock buried in my cunt, and my grandfather positioned himself behind me and put his into my ass, slowly, patiently, until I felt both of them inside me at once. They began moving in sync, one going up while the other came down, filling me on both sides, and there was a moment when pleasure overwhelmed me until it blurred my head, trapped between the two bodies that knew me best. I came once, twice, three times, screaming things I don’t remember, and they finished at the same time, one in each hole, leaving me dripping semen from front and back. Absolute madness.

My grandmother, now well into old age, gradually withdrew. My grandfather, on the other hand, kept the same vigor as ever. And I learned, before I turned twenty, that the secret my mother had confided to me that afternoon was not a burden. It was the most intimate inheritance of my family, and I still keep it, just as I promised.
