What My Mother-in-Law Discovered in the Pool That Night

The summer I turned thirty-nine fell in one of those July weeks when the air doesn’t move, not even at night. We had celebrated my birthday at home with a big crowd: my oldest friends and a few of my partner’s. Laughter, a table that ended up stained with wine, an inflatable pool for the kids, and conversations that dragged on until the sky began to lighten in the east.

Around two in the morning, the last four of us were still awake. Carolina, my girlfriend, suggested we stop by her parents’ house to return some utensils her mother had lent for the barbecue. Her brother Esteban came with us, and my son Bruno was sleeping soundly in the back seat of the car, his head tilted against the seatbelt.

—Five minutes —said Carolina—. We drop this off and go.

We parked in front of the house. It was a village house with an inner courtyard, a small pool at the back, and a hedge that blocked the neighbors’ view. From the street, there was no light in any of the windows, so we figured her parents were already in bed. Carolina and Esteban went in with the things, in silence, and went upstairs to say good night to their in-laws. I stayed outside, by the car, checking whether Bruno was still asleep. He was.

I went back to the patio and leaned against the wall. The pool, lit only by a yellow porch bulb, looked like a black mirror. The water was still. It was that hour when getting in doesn’t feel like a choice, but a natural consequence of the heat.

***

I don’t know exactly when I decided to undress. I remember doing it quickly, almost without thinking, piling my clothes on a plastic chair. I got into the water without making a sound and let myself float on my back, looking up at a patch of sky between the rooftops. The feeling of being naked in someone else’s pool, with everyone asleep and no one expecting anything from me, was a small freedom, but a real one. That was enough for me to forget where I was.

I’d been there about five minutes when I heard the kitchen door opening. Shit. The kitchen opened directly onto the patio. I saw a silhouette moving unhurriedly toward where I was. It was my mother-in-law. Beatriz.

The first thing I thought about was my clothes, which were far away. The second, that the light was weak but not nonexistent. And the third, that something about the situation, instead of making me feel completely ashamed, was starting to turn me on in a way I hadn’t expected. I felt my cock move on its own under the water, swell up all at once at the idea of being caught naked by my girlfriend’s mother.

I slid toward the nearest edge, trying to keep the water covering me at least to the waist. Beatriz came up to the rim with the easy confidence of someone who was at home and didn’t want to wake anyone.

—Well, well, my son-in-law —she said softly—. Good evening. How’s the swim? I see you’ve ended up alone, like me. My husband fell asleep on the sofa and went upstairs without telling me.

—The water’s great —I replied, trying not to sound as nervous as I was—. We thought nobody was awake in the kitchen anymore, there was no light. Carolina and Esteban went up to say good night to you. Since Bruno’s asleep, I came in for a minute.

—You make me envious —she said, fanning herself with her hand—. I don’t have my swimsuit handy, and if I go back inside, I won’t be coming out again.

I’d only known her for the two years I’d been with her daughter. Beatriz was fifty-six, with long hair tied up in a loose bun, some gray at her temples, a strong build, and the brown skin of summer. A little on the full side, with generous breasts and a wide waist. Her house T-shirt clung to her body, and it was obvious she wasn’t wearing a bra either: her large, heavy tits showed through, with hard nipples pressing into the thin fabric. I was thirty-nine, short-haired, normally built, and my cock was getting harder and harder, hanging heavy between my legs and half-floating, forcing me to hide it under the water.

—Don’t just stand there —I heard myself say, surprising myself—. If you feel like it, just get in. I won’t stare.

She gave a restrained laugh.

—Oh, come on, birthday boy —she said—. The drink’s given you courage. Do you really think I’m going to take my clothes off in front of my son-in-law and get into the pool like nothing’s happening? I’m not up for that kind of outing anymore.

—That’s the best way to do it —I insisted, turning around to face the fence and give her some chance to escape the conversation.

—Maybe another day —she answered—. For now, help me with something, will you? Since you’re already in there, you can save me the trouble.

She opened a little built-in cabinet next to the shower and took out two one-liter bottles and a few tablets. She brought them to the edge without really looking at me.

—Do a lap around the pool with the bottle, pouring the liquid along the wall. Put the tablets into those two floats and another into the filter. When you’re done, go to the switchboard, press the red button, and the pump will start. Understand?

—Perfectly.

—And shower afterward with soap —she added—. The chlorine will leave your skin a mess. The shower’s right there.

I opened the first bottle and started moving along the edge, spilling the liquid as I went. My mistake was not thinking that, as I moved away from my corner, I was getting closer to the area where the porch light fell more strongly. When I emptied half the bottle into the pool and leaned forward a little, I heard a click of the tongue behind me.

—Well, man —said Beatriz, with a mix of reproach and amusement in her voice—. I can see your ass, kid. Are you naked? Honestly…

I froze, bottle in hand and body half out of the water.

—Sorry —I said—. I thought nobody was around. I got in without thinking.

—I don’t mind —she answered—. But if my daughter shows up right now, she’ll kill you and she’ll kill me for not warning her. Hurry up, will you?

I gave another awkward laugh and kept going around. As I set the empty bottle down and picked up the second, her gaze reached me head-on. Even though the water covered me up to mid-thigh, there was no way to hide it completely. She saw it. I saw her see it. I saw her eyes stop right between my legs, on the half-hard cock hanging heavy, wet and shining, impossible to conceal. And I saw that, against all odds, she didn’t look away quickly. She licked her upper lip without even noticing, and only then did she lift her eyes again.

—You just showed me a lot more than I expected to see tonight —she said. Her voice wasn’t angry. It was… different. Lower, slower—. You’ve gotten carried away.

—Sorry, really. The light, the water, I didn’t judge it right.

—No, if anything, you judged wrong —she said, and gave a small laugh—. I’m going to get a towel, because if you stay like that you’ll catch a chill you can’t imagine.

She went into the kitchen. I hurried through the rest of the chlorine, the tablets, and the pump controls. I pressed the red button. The pump started with a low hum and, after a few seconds, tripped. I pressed it again. It tripped again. I got out of the water, still naked, and went straight to the shower, trying to focus on the chlorine and not on what had just happened. My cock hung hard between my legs, and there was no human way to bring it down.

Beatriz came back with a towel folded over her arm. I was soaped from head to toe, deliberately turned away, while I ran the sponge over my ass and my balls, unable to stop thinking about her look from two minutes earlier.

—I’m leaving the towel here —she said, but she didn’t move. She stayed there, leaning on the frame, watching me. I felt her eyes travel over my wet back, down my spine, settling on my ass—. Your girl’s coming down in five minutes.

—Okay, thanks. By the way, the pump tripped twice.

—That’s nothing new —she replied—. We changed it in the fall and sometimes it acts up. We’ll look at it tomorrow.

I turned around to reach for the towel. By then I didn’t care anymore. Or I wanted to convince myself I didn’t care. I met her gaze, this time with no water between us, no shadow hiding anything. Beatriz didn’t blink. She lowered her eyes slowly to my groin and stayed there for a long moment, looking at my hard cock, thick, pointing upward, its swollen red tip begging for trouble. Her lips parted a little. She swallowed. Then she slowly lifted her eyes again, as if she had all the time in the world.

—In the end, I’m going to stop caring about seeing you naked —she said, while extending the towel to me, not quite letting go of it, forcing me to take a step closer to her—. I thought you were shy, but now I see you’re not that shy with me. And, look, I don’t mean to offend my daughter, but that body doesn’t belong just anywhere. And that thing you’ve got hanging there… what a gift my girl got, damn.

—Beatriz…

—And on top of that, hard as a rock —she whispered, almost to herself—. What a son-in-law I brought home.

She extended the towel and, when I took it, her fingers brushed mine and then deliberately brushed my thigh, very close to my groin. It wasn’t accidental. I didn’t pull away either.

—Good night, son-in-law —she cut in—. We’ll talk another day, calmly. About the pump and… the other thing.

She went into the kitchen and closed the door slowly. I stayed for a moment under the warm shower water, with the towel half tied around me and my heart racing at a speed I hadn’t felt in years. My cock was still hard as stone. I dried off quickly, got dressed, and checked on Bruno for the umpteenth time. He was still asleep like a log.

***

—Darling! —said Carolina behind me, appearing in the patio—. How was the bath?

—Spectacular —I answered, slipping an arm around her waist—. Like new.

—It’s almost three —she said, looking at the clock—. Pablo and Sofía called me. They were having a last drink at Sofía’s brother’s place and suggest coming back to ours for a while. What do we do? Since Bruno’s asleep, better at home than here, right?

Pablo and Sofía are two friends who don’t live in the village. They had come to the birthday and were spending the night at her brother’s place, five minutes away on foot.

—Tell them to come over —I replied—. One last one and then bed.

We kissed in the darkness of the patio. Carolina’s hand slid over my pants and grabbed my cock, which was still half-hard from everything that had happened. She stopped abruptly.

—You’re weird —she murmured, squeezing it without letting go—. And you’re hard. Did something happen in my pool?

—Nothing —I said—. I’ll tell you when they get here.

—Oh, no —she said, lowering my fly with two fingers and slipping her hand inside—. You tell me now.

She took my cock out right there, in her parents’ patio, and looked at it for a second as if she needed to check it was real. Then she dropped to her knees without saying another word, gripping the base with her right hand and taking the tip into her mouth without warning. I felt her hot tongue circle my glans and go down, then back up, and down again, deeper, until her mouth was full of my cock.

—Fuck, Carolina —I gasped, bracing myself on the car hood—. Not here.

She didn’t answer. She kept sucking me in her parents’ patio, her tongue circling under the glans, hollowing her cheeks to create more suction, swallowing as my cock sank into her throat. She pulled it out for a second, shiny and dripping.

—You’ll tell me at home —she said softly, with that half smile I knew by heart—. But something happened. You never get this hard after a bath.

She took it back into her mouth, this time all the way to the back, and slowly pulled it out, her tight lips sliding along its entire length. She stood up, carefully tucked it back into my pants, and pulled up the zipper as if she had just sewn on a button.

—Home —she said—. We’ll continue there.

We put Bruno to bed in his crib at our place. Carolina put on a short pajama set, shorts and a T-shirt without a bra, and everything showed: her nipples standing out like stones against the white fabric, her medium, firm breasts moving freely with every step, the shorts so short you could see the curve of her ass when she bent over. Pablo arrived, thirty-three, dark-skinned, with curly hair and broad shoulders, already pretty wrecked by the night. Sofía came in behind him, twenty-seven, blonde and curvy, wearing a neckline she kept glancing down at whenever she drank. We poured four drinks and sat on the living-room sofa.

Pablo, who was the drunkest of the four, started with his usual nonsense.

—You got a woman’s pajama I can borrow? —he asked Carolina—. I’m going to change, because my clothes are stuck to my body. Let’s see if I can have a laugh.

—I’ll lend you one of my short bottoms —she replied, laughing—. And one of Diego’s old T-shirts. Let’s see how it fits you.

When he came back, Pablo had put on Carolina’s shorts, which fit him ridiculously tight, and he was strutting around the living room like it was a runway. The girls were laughing their heads off. I couldn’t focus. My mind kept drifting to Beatriz, to that long look in the shower, to her fingers brushing my thigh when she handed me the towel, to that final sentence. My cock kept swelling on its own inside my pants every time I remembered.

—Tell us, tell us —said Sofía, noticing my distraction—. You look like you’re in on something.

—Something happened in my mother’s pool —said Carolina, looking at me with a smile that had me caught—. My mother said something as she was leaving, but she wouldn’t tell me what. And this one showed up with a hard-on. So something happened.

I had no choice. I told them. I told them about the swim, the chlorine bottle, going around the pool naked, how she saw my ass and then my half-hard cock, the pump, the shower with her watching me from the doorframe, how she pinned me with her eyes between the legs and how she brushed my thigh when she handed me the towel. I told it more calmly than I felt. Pablo was laughing his ass off. Sofía watched me without blinking, biting down on her smile, and without much effort at hiding it, letting her gaze drop every now and then to my groin.

—Fuck —said Pablo—. What a birthday debut. She saw you all the way, hard as a rock, and on top of that your cock was dripping on you in the shower. And you there, like some model.

—My mother has no idea what she saw —said Carolina—. Or rather, my mother doesn’t believe what she saw. I didn’t get any more out of her, so I’ll talk to her tomorrow.

—And does that bother you? —I asked, looking straight at her.

—It would bother me if you’d hidden something from me —she replied, not blinking—. It doesn’t bother me that my mother saw your cock. It’s strange what I’m about to say. But hearing it turned me on a bit. In fact, it got me hot. Look.

She grabbed her T-shirt and lifted it for a second, showing the three of us her hard tits, with nipples so stiff they looked painful. Then she dropped it back down, laughing.

—I got my panties wet imagining my mother looking at it —she said—. There. I said it.

Pablo, true to form, decided that could not be left there. He grabbed my arm.

—Let’s go to the kitchen —he said—. We need to see whether what your mother-in-law saw is really that much or if she was exaggerating.

I let him lead me. In the kitchen, Pablo pulled down Carolina’s shorts without any drama, revealing an ordinary cock, on the short side, half-hard. He looked at me, expecting me to do the same. I did, almost by force of habit. I had already made up my mind that night’s shame had stayed somewhere else. I dropped my pants to my knees and my cock sprang out, thick, long, half-hard again from all the time I’d spent telling the story.

—Jesus Christ —said Pablo, staring openly—. Okay, she wasn’t exaggerating. Damn, man, this is another league.

The girls appeared in the doorway like two judges arriving to deliberate. Sofía gave a short laugh, and then the laugh stuck halfway when she lowered her eyes to my cock. Her gaze stayed there. She didn’t look away.

—Baby —she said to Pablo, never taking her eyes off my cock—, if he’s bigger than you. Twice as big. But I don’t care.

—Yeah, yeah —said Pablo—. Thanks for the support.

Carolina came toward me slowly, with that way of walking she had when she’d already decided something. She moved my hand off my thigh, leaned in, and kissed me with a calm that had nothing innocent about it. Her hand went straight down to my cock and took it fully, squeezing my base with all five fingers while she looked me in the eyes in front of the other two.

—It’s rock hard —she said softly, but not so softly that they couldn’t hear—. Still hard from my mother, right?

—Yes —I confessed.

She started jerking me slowly, with her hand closed, sliding up and down my entire length, while Pablo and Sofía watched from the doorway without moving. She squeezed back my foreskin, worked her fist around my glans, rubbed her thumb over the tip, and gathered a thick drop that had formed there. She took it into her mouth without taking her eyes off me.

—Suck it —she told Sofía, never looking away from my eyes—. I’ll watch. And then we’ll continue on the sofa.

Sofía looked at Pablo. Pablo shrugged with a half smile and a drink in his hand.

—I’m not getting involved —he said—. But I’m not leaving either.

Sofía came over and knelt in front of me, her dress skirt riding up her thighs. She took my cock in her right hand, weighed it for a moment, then stuck out her tongue to run it under the glans, very slowly, from bottom to top. She took it all in one go, to the back, and I felt her throat tighten around me as she swallowed me. She pulled back, spat saliva on the tip, and wrapped her lips around it again.

Carolina stood behind me, bit my shoulder, and whispered in my ear while watching my cock disappear into her friend’s mouth.

—Think about my mother —she said—. Think about the way she looked at you. Think about how she would have gotten if, instead of handing you the towel, she’d knelt the way Sofía is doing. Think about my mother’s mouth, my love.

—Fuck, Carolina —I gasped.

—Think about it —she insisted, squeezing my jaw with her hand—. And come thinking about it. In Sofía’s face. So we can all see what you would have done to my mother.

Sofía sucked me like she was hungry, hollowing her cheeks, taking my cock all the way in and pulling it out again, strings of saliva hanging from her chin. She grabbed my balls with her other hand and squeezed them gently, and that was when I couldn’t hold back anymore. I grabbed her head with both hands, pulled her off for a second, and came with the first load hitting her open mouth and outstretched tongue, the second on her cheek, the third falling between her breasts, while Carolina panted against my back, pressing herself to my ass and whispering her mother’s name.

Sofía shook her head, laughing, licked her lips, and used her hand to wipe the thread of semen hanging from Carolina’s chin. Pablo, true to form, raised his glass toward the ceiling, toasted the air, and said nothing for a long while.

—The truth is —said Carolina, looking me in the eyes, still breathing hard—, the last thing I imagined tonight was my mother seeing you naked. And even less like that. So maybe… since we’re here… I don’t exactly rule out it happening again. With me there, of course.

I didn’t know what to answer. I just nodded. Sofía pinched Carolina’s thigh and stayed on her knees a little longer, playing with what was left of me on her tongue. And the night became something else. Something that no longer fits in this story.

But that first look from Beatriz, the one that lasted a second too long at the edge of the pool, was what opened everything. And to that look, we’re going to have to come back.
