My Mother-in-Law Asked Me to Come Up to Her Office That Afternoon

It had been a few days since the fight with Camila. She was furious because I refused her proposal to have children with her and her cousin, to set up a stable threesome, to live together under the same roof raising the kids as if it were the most natural thing in the world. She said it was a chance to smooth over old tensions with her cousin, that this would finally bring them closer. I couldn’t see the logic in it.

Lucía, the cousin, called me every night. She promised me that if the three of us moved in together, she’d quit her job at the cabaret and devote herself only to nursing. I listened in silence and hung up with my stomach in a knot.

On Wednesday my mother-in-law called me. She wanted to know what had happened, to hear it from my mouth and not through crossed-up versions. We arranged for me to pick her up from the office late in the day, grab a coffee nearby, and talk calmly.

When I got off work, I drove the fifteen minutes to her building. I parked, texted her, and she replied that I should come up, that she was delayed with a report and didn’t want me freezing downstairs.

The elevator took me to the fifth floor. Susana was sitting in front of her monitor, finishing a spreadsheet, with the white fluorescent light falling over her tied-back hair. At the adjoining desk, separated by a glass panel that ran from floor to ceiling, was Damián. The married guy she’d been involved with for two or three years. The office was empty at that hour except for the two of them.

—Come in, come on —she said without lifting her gaze—. Give me two minutes and we’ll go.

I stood behind her chair, put a hand on the backrest, and leaned in to read the screen. There was a column with a total that didn’t match the manual sum. I pointed out the inconsistency and started explaining where the error was.

Then I felt her hand.

It went over the pants first, a brush, then a firm pressure searching for the bulge and squeezing it with her open palm. I went hard instantly. Susana didn’t even turn her head.

—Stop, mother-in-law —I said, lowering my voice.

—I don’t want to.

—Damián is right next to us. He could see us.

—I want him to see us. I want him to see how you fuck me, son-in-law. I want him to die of jealousy watching this bitch swallow another man’s cock.

—Let me finish with the spreadsheet.

—Forget it. The report is done already. I asked you to come up for this, so you’d fill my mouth and my cunt.

—You’re terrible.

—Yes. I am.

With one hand she lowered my zipper like someone doing something she’d practiced a thousand times. She slipped her fingers into the opening of my boxers, grabbed my cock from the base, and slowly pulled it out, weighing it in her hand. It was already hard as iron, the tip shining. She spat on the head and started stroking me with her wrist turned, squeezing the glans and easing at the base, setting a slow rhythm that made me brace one hand against the wall so I wouldn’t lose my balance.

—Look how hard you get, little one —she murmured, never stopping the pumping—. It’s dripping all on its own. Come on, give it to me.

I sat on the edge of the desk and she turned the chair until she was at the perfect height. She tucked her hair behind her ears with the professional gesture I’d seen a thousand times at family gatherings, and then she opened her mouth. She ran her tongue from bottom to top, following the thick vein that runs under the head, with a slowness that seemed calculated to drive anyone watching insane. She sucked my balls one by one, took them into her mouth, and let them go with a plop that echoed in the empty office. She went back up. When she got to the top, she opened wider and swallowed me whole, all the way to the root, until I felt her nose flattened against my stomach and her throat squeezing the tip. She stayed there for a few seconds, eyes watery, then slowly withdrew, leaving a long strand of saliva hanging from her chin.

And someone was watching.

Through the glass I saw Damián. He had his chair turned toward our side, his pants loosened, his cock out, and his hand moving over his erection without hiding it at all. He held my gaze for a second and then went right back to staring at Susana’s mouth, which was now going up and down in an obscene rhythm, making noise on purpose, sucking hard every time she got to the tip.

I didn’t let her keep going. I lifted her by the hair gently, laid her against the desk facing the glass panel, pulled down her dress pants and panties in one yank. She had a white, round ass, still firm for her age. I spread her cheeks with both hands and saw her cunt, swollen, wet, with the lips parted. I spat between her cheeks, let a thick string fall that ran down to her ass, and drove into her from behind with one hard thrust. She stifled a moan against her forearm and her knees buckled. I grabbed her by the waist and started fucking her hard, pulling almost all the way out and burying back to the hilt, while her breasts shook loose inside her blouse. Damián, on the other side, sped up the rhythm of his hand.

—Like that, like that, like that —Susana gasped, biting the edge of the desk—. Break me, son-in-law. Fuck me like a bitch. Let Damián see how you fill me up.

—You like being watched?

—I love it. It makes me even sluttier. More, more.

—I’m not going to let you leave the family —Susana whispered, her voice breaking—. I’m not losing this cock, not for anything. Keep going, son-in-law. Keep fucking me here, in my office, because I’m burning up.

I pulled out of her, turned her around, sat her on the desk and pushed her gently so she would kneel. I grabbed her head with both hands and shoved my cock, wet with her own juices, into her mouth. She took it hungrily, tasting herself off of it. I looked at Damián over my mother-in-law’s shoulder and motioned with my chin. Come here.

He came out of his office as best he could, walking awkwardly with his pants halfway down his legs. He shut the door behind him. He had his hard cock in his hand, thick and curved, already glossy from all the stroking.

—Nice to meet you, Damián —I said.

—A-and likewise —he stammered.

—Mother-in-law, get up. Damián’s going to fuck you from behind while you keep going here.

She obeyed without a word. She leaned over the desk, took my cock into her mouth again and spread her legs. Damián stood behind her, grabbed her hips, and buried his cock in her cunt with one thrust that made her moan against me, mouth full, sending a vibration all the way up my back. I grabbed her hair, set the pace, pushing her head all the way down each time Damián slammed her hips against her ass. Damián looked me in the eyes while he fucked her. There was rage there, and something darker too. His jaw was clenched and the veins in his neck stood out.

—You’re never this much of a whore with me —he told her, speaking into her ear without stopping his thrusts.

—Today I’m collecting everything —she answered, pulling my cock from her mouth for a second to speak, her chin covered in saliva.

He came out of her cunt and drove in without warning from the other side, in her ass, all the way in. Susana threw her head up and let out a scream that bounced off the glass.

—Ah, animal, warn me! You split me open!

—You’ve had me dry as a bone for two weeks —he answered, breathing hard, never stopping his fucking from behind—. Your son-in-law comes in and you fuck him in front of me, without asking me anything. Now you take it.

—You got turned on, didn’t you? —Susana smiled again, panting, tears running her mascara—. I saw you masturbating while you watched me suck him. I saw you get hard when he was inside me. Go hard now, daddy. Tear my ass apart. I’ve wanted this for a long time, both of you at once, both holes occupied.

Damián sat in the leather chair behind the desk, his cock standing straight and pointing at the ceiling. Susana settled on top of him facing away, grabbed his cock with her hand, positioned it at the entrance to her ass and lowered herself slowly, her mouth open in a silent O, until she sat all the way down on him. She ended up facing me, legs spread and cunt on display, throbbing, shining. The idea was obvious. I went over, held her thighs, and fucked her from the front, driving my whole cock into her in one shot. I felt Damián’s pressure through that thin membrane that separated everything, the skin of both our cocks rubbing inside her, and for a second my vision blurred. Susana closed her eyes, threw her head back against Damián’s shoulder, and started moving between the two of us with a desperation I’d never seen in her.

—Ah… ah… what pleasure, both of you, both at once, I can’t take it, fill me, please, fill me.

We started moving in sync, one rising while the other went down, alternating inside that body trembling between us like a taut rope. I grabbed her tits, squeezed them, pinched her hard nipples until she moaned. Damián bit her neck from behind, called her a whore in her ear, told her to take it well. Susana lost the thread of words and just kept repeating yes, yes, yes, yes, faster and faster, until her voice broke into a muffled scream.

She clenched everything. She closed around both cocks at once, with a spasm that shook her whole body. Damián growled something I didn’t understand and I felt him cum inside her ass, pushing hard, emptying himself. I clenched my teeth until my jaw hurt, held on for two more thrusts, and shot inside her too, mixing my load with his through that thin skin. The three of us finished almost at the same time, in a tangle of breathing and hands groping for something to hold onto.

Susana stayed impaled between the two of us for a few seconds, head hanging, panting. When she got up, a thick strand of semen ran down the inside of her thigh. She wiped it off with the back of her hand and brought it to her mouth, looking me in the eyes.

I went to the bathroom to pull myself together. Susana went to the women’s room. Damián stayed in the office, answering the phone that wouldn’t stop vibrating on the desk: his wife’s name flashing on the screen.

I washed up well, adjusted my shirt, ran my fingers through my hair in front of the mirror. When I came out, Damián had already hurried off. My mother-in-law was in the hallway, looking at herself in the reflection of the window.

—Fucking assholes —she said, with a tired smile—. Look what you did to me. I had to wash myself three times. Both of you had me dripping inside.

—Damián left. They called him home.

—Even better.

—Are we going?

—You in a hurry?

—You got something in mind?

—Mmm. Nothing in particular.

The intercom buzzed. Susana answered, frowned, and pressed the button to open. A minute later the elevator opened and Antonella appeared, my sister-in-law. She had just turned eighteen and still had that sweet clumsiness of a young adult learning to move in a woman’s body.

—Hi, Mom! —Antonella took off her backpack and dropped it on the floor—. What was that urgent thing you wanted to show me?

—Come into the meeting room —Susana replied, already composed—. I need your help with something.

Antonella saw me and ran to hug me. She squeezed me hard, burying her face in my chest.

—I don’t want you to leave the family —she murmured—. I’m going to miss you so much, brother-in-law.

She started kissing my cheek, my jaw, my neck. She kept repeating the same sentence through tears, don’t go, don’t go, please. I didn’t know how to stop her. I didn’t really try all that hard either. I felt her pressing against my bulge, rubbing slowly, and her nipples hardening through the thin sweatshirt.

Susana opened the meeting room door and motioned for us to go in. Inside there was a large worn leather couch and a long table for ten people. Antonella climbed on top of me as soon as I shut the door. We kissed like we were fifteen, with that clumsy urgency, biting each other’s lips by accident, tongues knotting together. She kept reaching for my hand and taking it between her legs, pressing it against her mound over her skirt.

I lifted her sweatshirt. Underneath she had a plain white cotton bra. Her breasts were small, perky, with pink nipples that stood out hard under the fabric. I thought about her age and for a moment I stopped. She didn’t let me keep thinking. She took my hands and put them on her breasts, pressing my fingers down over her nipples.

—I love you, brother-in-law.

—How am I supposed to stop seeing you?

—We all love you —Susana said from the doorway, watching us without coming in—. We’re not going to let you go because of one crazy idea from your sister.

Antonella wore a short pleated skirt. I started lifting it until her panties, the same color as the bra, came into view. I pulled those down too and tangled them around one ankle. She had almost no hair on her cunt, just a faint blond shadow, pink lips already shining with wetness. Susana, who had finally closed the door and knelt between my legs, pulled my pants off with the familiarity of someone who’d done it a hundred times. She grabbed my cock, still coated with our previous encounter, and without disgust took it back into her mouth to clean it and make it hard again. Antonella, in an awkward, enthusiastic movement, settled on the other side, kissing my mouth while her mother sucked me below.

I was still sitting on the couch. I moved Susana away with my hand, grabbed Antonella by the waist, and lifted her until I had her cunt against my face. I ran my tongue between her lips from top to bottom, searching for her clit, taking it between my lips and sucking it slowly. Antonella let out a sharp little moan every time I brushed her with the tip of my tongue. She was so young, everything worked for her at the first touch, and even so she got desperate as if nothing were enough. I slid in one finger, then two, looking for the spot inside, and she pressed my head with her thighs, moving her pelvis against my mouth. Susana, meanwhile, had never stopped sucking me, and every now and then she took my balls into her mouth, wetting everything.

—Oh, brother-in-law, like that, there, there, don’t stop.

After a while Susana got up without saying anything, took her pants off again, and settled over me from behind to pick up where we’d left off in the office. She sat down on me slowly, letting her used, still dripping cunt swallow my cock centimeter by centimeter, all the way in. She started moving up and down with a slow, expert rhythm. Antonella sat on my face, rubbing herself without really knowing what she was doing but with more instinct than enough, and there we were, stacked in three layers, daughter over my face, mother over my cock, both of them moving. It was hard to breathe and I didn’t care. Susana stretched out her arms and grabbed her daughter’s tits from behind, pinching her nipples. Antonella let out a little yelp and sank down harder against my mouth.

—Mom, what are you doing?

—Shut up and enjoy it, baby.

I felt Susana cum on me, clenching everything, with a long shiver that started in her legs and climbed up to her neck. When she was done, she got up, fixed her clothes with trembling fingers, and left the room without looking back. I guess she needed air. Antonella took her place. She knelt between my legs for a moment, grabbed my cock with both hands, and gave the tip a few clumsy licks, sucking it with more eagerness than technique. Then she lay down on the carpet and stretched her arms toward me.

—Make love to me, brother-in-law.

—Of course, little sister-in-law.

I settled over her slowly, measuring every inch. I took my cock in my hand and ran the tip over her cunt, up and down, soaking it well in her juice. When I placed it at the entrance, she let out a long sigh. I pushed in little by little, feeling how she opened by millimeters, until I was all the way inside. She was incredibly tight, squeezed, hot. She wrapped her legs around my hips and pulled me deep. Her eyes were open, looking at me like she wanted to memorize my face for later.

—Make me feel like a real woman, little brother-in-law.

I started moving without going wild. I came out almost all the way, went back in slowly, played with the head at the entrance, pulling it out completely and sliding it back in so I could see her face every time. She was trembling.

—Oh… oh… I love feeling you like this. You’re huge inside me.

—You’re so beautiful, Toni. You’re so tight.

—Now fuck me hard. Fuck me hard, don’t hold back.

She grabbed the back of my neck and kissed me deeply, biting my lower lip. I sped up. Our hips slammed together in a dry rhythm that filled the whole room, with that wet skin-on-skin sound and the sloshing of her soaked cunt swallowing my cock. I grabbed one leg, lifted it, rested it on my shoulder to get in deeper. Antonella was laughing and moaning at the same time, a strange mix of pleasure and something like victory.

—Am I behaving myself, baby?

—You’re behaving beautifully. You’re an incredible little female.

—Give me your cum, brother-in-law. Give it to me inside.

Then she herself pushed me gently to pull me out, led me to a chair, and sat on top of me facing me, hugging my neck. She grabbed my cock, positioned it at the entrance, and lowered herself slowly until she buried it all the way, throwing her head back with her mouth open. She started moving up and down, first to her own rhythm, then to mine. I grabbed her ass with both hands, lifting and lowering her, setting the pace. She squeezed my jaw with one hand, kissed me with her mouth open, told me things in my ear I’m not going to repeat, things from a little slut wanting to learn how to be one.

—Cum inside, brother-in-law, I want to feel you, I want you to fill me, don’t pull out.

When I couldn’t hold back anymore, I gripped her ass hard, pushed her down to the hilt and shot inside her, with long spasms that filled her cunt with my load. She moved only slightly on top of me, milking me dry to the last drop, and stayed there seated, impaled, trembling. When it was over, she was crying a little. She took my face in her hands and looked at me with a seriousness I’d never seen in her.

—Thank you, brother-in-law. Thank you, my love.

If Camila was crazy, this one didn’t have all her ducks in a row either. I was starting to understand that the whole family ran on different wiring than the rest of the world.

I straightened my clothes. Susana was waiting at reception, ready to go, as if nothing had happened. I kissed each of them, and we went down in silence. The visits to Camila’s house continued, but less often. I no longer stayed every weekend.

***

A month later, I got a call from my father-in-law. He wanted to see me in his office. He’s a lawyer, with a downtown practice and walls lined with books nobody reads.

I arrived on time. Inside were Camila, Antonella, Susana, the girls’ uncle with a sour face, his wife, and two other lawyers I didn’t know. Something didn’t add up.

—We had you come —Fernando began— because when the girls’ grandfather died, he left a testamentary clause. The first grandchild to be born would inherit the ranch, the livestock, and two houses that are now rented out. The rent accumulates in an account we brothers manage.

—Great. But what the hell does that have to do with me?

—Didn’t they tell you? I thought you knew.

Camila had red eyes. Susana was holding her hand. Antonella stood up, came over to me with a wooden envelope and rested it on my thigh.

—Love, I’m pregnant. We’re going to have a baby.

The office floor seemed to shift under me a little. Someone brought me a glass of water.

—No water. Whiskey, please.

—Bring my son-in-law one of the ones I’ve got put away —Fernando ordered.

Antonella sat down beside me and took my hand. She was gripping it hard.

—We’re going to be very happy.

—There’s a condition in the will —Fernando continued, without emotion—. For the kid to inherit, the parents have to be married.

I looked at Camila. She shrugged and gave a broken smile.

—You’re free. You’re still family anyway.

Two months later I had a wedding date with Antonella. Everything arranged, everything signed.

—Fernando —Susana said one afternoon, pouring herself a drink—. This young man deserves a bachelor party God intended, doesn’t he?

—Obviously. We’ll do it this weekend at the country house. And tell your boyfriend to come too.

I raised my glass, not knowing whether to laugh or run.

Welcome to the family, dear son-in-law.
