My Mother-in-Law Caught Me Naked in the Pool

The summer I turned thirty-eight was the hottest I can remember. July arrived early and settled in without warning: a mass of heat that flattened the city from noon onward and that, even at dawn, left the asphalt warm underfoot. For my birthday we had booked a table in the garden of a restaurant on the outskirts, where at least a little air moved.

There were twelve or fourteen of us at first. The night kept lurching forward with that rhythm good celebrations have: first the table, then the drinks, then the laughter, then someone suggests moving on and the group splits up. By the time I realized it, it was almost two in the morning and there were four of us left: my girlfriend Verónica, her brother Sergio, my son Marcos —who had fallen asleep in the back seat of the car before we even left the parking lot— and me.

We stopped at Verónica’s parents’ house to return some kitchen molds Clara, her mother, had lent us for the celebration. The kitchen was dark. The living room too. We figured they were asleep.

We went in quietly, left the molds on the counter, and Verónica and Sergio went upstairs to say good night. I went out to the patio to check that Marcos was still asleep. He was, head tilted toward the window and mouth slightly open.

I went back out to the patio and stood still in front of the pool.

It was a medium-sized, round, in-ground pool. The water was perfectly still. The garden lanterns were reflected on the surface, distorted and trembling. There was no sound except the distant hum of the filter and, every so often, the rustle of bougainvillea leaves against the metal fence.

No one was looking.

I took off my T-shirt first, then my shoes and socks, then my trousers, and finally my briefs. I left them neatly stacked on a plastic chair beside the edge. My cock hung heavy between my thighs, half-hard from the simple novelty of being outdoors naked, with my balls loose and dangling, moving with every step I took toward the edge. The warm dawn air licked my cock like an invisible tongue. I stepped into the water in one motion from the edge and the temperature ran through my body from bottom to top like an electric current.

It’s almost impossible to describe that sensation well if you haven’t experienced it. Water without fabric between you and it is something completely different. Your body notices everything: the exact temperature, the slightest movement of the currents, the light pressure of the liquid on every inch of skin. The cock especially —without a brief to hold it in place— floats free, moves with every current, every kiss of the water against the glans, every brush against the frenulum, and feels magnified to absurdity. I stayed still for a moment, water at my waist, feeling my cock go semi-hard for no particular reason, just because of the novelty, while my balls swung heavy beneath me. Until my pulse settled.

Then I leaned back and floated, staring at the sky. My cock, now a little softer, poked above the water every time a tiny wave lifted me, rising and falling with the rhythm of the water like a flesh buoy.

I’d been like that maybe ten minutes, drifting slowly from one end of the pool to the other, when I heard the unmistakable sound of a screen door opening.

I sat up sharply.

The kitchen door had light on inside. A figure stepped into the patio at an easy pace. I recognized her before she had reached the halfway point.

Clara. Fifty-five years old. Brunette, with long hair streaked with gray. Strong-built, like someone who’d carried weight all her life without ever complaining about it. She was wearing a light spaghetti-strap nightgown so thin that, backlit by the hallway lamp, everything showed through: her big breasts hanging free without a bra, two dark nipples pressing against the fabric every time she breathed, the dense triangle of pubic hair faintly outlined where the cloth clung to her belly with sweat. Rubber sandals. She walked looking at the ground, mind elsewhere.

I sank to my shoulders and pressed myself against the inner ledge. My cock, under the water, seeing her like that, had gone fully hard without asking my permission.

When she looked up and saw me, she put a hand to her chest.

—Damn! —she said—. Rodrigo, you gave me a scare. I didn’t hear the car come in.

—Sorry —I answered—. We thought you were asleep. The kitchen was dark.

—The living room was. But I couldn’t sleep with this heat. —She took two more steps toward the edge of the pool. The nightgown clung to her stomach, showing the shadow of a deep navel—. How was the birthday? Did you have a good time?

—Very good. A great time. —I paused. Under the water my cock was like a stone, pressed against my belly so the bubbles wouldn’t lift it to the surface—. Hey, Clara, I’ve got to tell you something.

—What’s up?

—I’m not wearing a bathing suit.

Silence.

Clara looked at me with narrowed eyes, as if waiting for the punchline. Then she followed my gaze to the chair by the edge. The T-shirt, the trousers, the briefs, all neatly piled up.

She let out a short, dry laugh.

—You little idiot —she said—. And how long have you been in there like that, with your cock out in your mother-in-law’s pool?

—Since I got here. About ten minutes.

—Good thing my husband didn’t come out to check the pool, he usually does. —She crossed her arms under her breasts, pushing them upward without realizing it, still laughing—. Verónica and Sergio upstairs saying good night, and you down here stark naked showing your ass to the stars.

—In my defense, no one was around.

—Yeah, yeah. —She shook her head—. Lucky for you I have a sense of humor.

The conversation had calmed me down up top, but down below my cock was still so hard against my belly that I was starting to worry about the moment I’d have to get out. Clara had that ability: to turn awkwardness into something manageable, almost normal. I’d been with her daughter for nearly three years and had never seen her lose her composure over anything.

—Don’t leave on my account —I said, now that I’d relaxed enough—. The water’s incredible tonight.

—What? Are you inviting me? —she asked, raising one eyebrow.

—If you feel like it, go ahead. I don’t have any problem with it.

Clara looked at me for another second, then sat on the edge, her legs hanging over the water without quite touching it. As she sat, her nightgown rode up to mid-thigh, and from where I was, a meter and a half below, I had a direct angle to what was above those thighs: she wasn’t wearing panties. Nothing. Just the thick hair, still almost entirely black, covering a cunt with thick lips that peeked out at the bottom of the triangle. I looked away quickly, but she noticed.

—The bathing suit’s inside —she said, her voice unchanged, though a trace of a smile had hooked itself at the corner of her mouth—, and if I go in to get it, I won’t come back out. And to be honest, I’ve wanted to get in all night. This heat is unbearable.

—Well —I replied, my throat a little dry—. You don’t have to worry about that detail.

—That was very bold of you, Rodrigo.

—You’re pretty bold too, sitting there like that, with your legs open.

She looked down for a moment, toward the gap between her thighs, and instead of closing them she left them exactly where they were. She went quiet for a moment, feet brushing the surface. Then she laughed, harder than before.

—Hey —she said—, since you’re already in there anyway, do me a favor? I’ve been putting off adding the chlorine for two days. If I don’t do it tonight, the water’ll be green tomorrow.

—Sure. Tell me how to do it.

Clara stood up, went to the side cabinet, and came back with a one-liter bottle and a smaller one, plus some tablets in a plastic bag. When she crouched beside me to leave the things on the edge, her nightgown opened at the top and I got a full view of the valley between those two big, soft tits hanging forward with the weight of the flesh, nipples already hard though I still didn’t know whether it was from the dawn air or something else. She explained it with a precision that made it obvious she’d done it many times before: one full lap around the perimeter, pouring out the liquid from the big bottle, the tablets distributed among the floats and the filter, and then the switch on the electrical panel by the fence.

—Any questions?

—None. Got it.

I started with the nearest side. I walked along the inner edge tilting the bottle, with no trouble as long as I stayed in the deep end where the water reached my shoulders. The problem came when I turned toward the opposite side, where the pool was shallower. The water dropped to my waist, then to my thighs. My ass was left exposed, white under the lantern light, with the two wet half-moons shining every time I moved.

—Rodrigo —Clara said, with a voice that held something halfway between reproach and laughter—. I can see your whole ass.

I stopped for a moment.

—Yeah —I admitted—. I suppose so.

—Nice ass you’ve got, kid. Firm, tight. You take care of it. I never told you because it never came up.

—Clara.

—What? It’s a compliment, don’t be such a prude. Keep going, keep going. Since you’re halfway through, there’s not much point stopping now.

I kept going. I could feel her eyes fixed on my back, sliding slowly down my spine until they stopped exactly where the water licked my waist, entering and leaving the crease of my ass with every step. My cock, which had calmed down a little with the walk, rose again. I finished the circuit and went back to the deep end. Clara was standing by the electrical panel, one arm extended toward the switch. She pressed the button. The filter motor started for three seconds and cut out.

—It’s tripped. —She pressed again—. There’s a short somewhere, always has been. When you turn around, press it from here yourself.

I turned toward the panel.

The water there reached halfway up my legs. Everything else was out in the open, wet, gleaming under the yellow light of the lantern: my belly, navel, dark pubic hair, and my cock, which by that hour of the night there was no way to hide anymore. It was hard. Completely hard. Pointing upward, thick, with the glans shining with water and my balls pulled tight beneath it, strained and lifted against my body. There was no way to cover it because both my hands were occupied with the empty bottle and the tablets, and anyway covering it would have been worse than leaving it visible: it would have admitted what was already obvious.

The motor started and kept going.

And Clara saw me straight on.

She said nothing. Neither did I. The filter hummed with its steady rhythm. Small ripples formed around my hips. Four or five seconds passed that felt much longer. Clara’s eyes were fixed exactly where I knew they would be: on my cock, stiff and thick, pointing at her as if indicating her. I saw her swallow. I saw her part her lips a millimeter. I saw her lower her right hand to rest it against her own thigh over the nightgown, and leave it there, still, fingers slightly spread, as though restraining herself from sliding them farther up. Her nipples had hardened under the fabric, two dark, firm points pushing forward with each breath that was a little faster than normal.

—Well —she said at last, in a completely different voice, lower, raspier, as if suddenly it was hard for her to get the air out—. Now we really should call your girlfriend to come down.

—She’s inside, yes.

—I know that. —She paused briefly. She still wasn’t looking away from my crotch. Her tongue flicked out for a second, wetting her upper lip, and disappeared again—. Rodrigo, are you wearing glasses or something?

—Not that I know of.

—It’s just that I had laser surgery in the winter. I can see perfectly now. Everything. The details. I just wanted you to know that.

I looked down at my cock again, still rigid, still pointing at her. When I lifted my gaze, she was still looking. Without hiding it. Without an excuse. Her hand still resting on her thigh, a little higher than where it had started.

She picked up the empty bag from the floor with a slow movement, as if she didn’t quite want to leave, and headed toward the kitchen door without hurrying. Before going in she turned back one last time. Her gaze dropped again, with no shame at all, lingered there for an instant, and rose slowly:

—The towel’s on the hook by the outdoor shower. Use the soap there, chlorine stains the skin. And when you get out, hit the switch again, because it’ll trip once more.

—Clara.

She stopped without fully turning around.

—What?

—I’m sorry.

There was a pause that lasted exactly long enough not to be innocent.

—Don’t be too sorry —she said—. There’s nothing there to be sorry about, kid. Good night, Rodrigo.

And she went in.

I stood there leaning against the edge for a long minute, with my cock still so hard it hurt, with my heart buzzing in my ears louder than the filter. I got out of the water slowly, dried myself off fast, and got dressed with my cock painfully squeezed inside my briefs.

Verónica came out to the patio when I was already getting dressed. She had her shoes in her hand and wore that affectionate suspicious expression she got when something didn’t quite add up.

—Why were you taking so long?

—Your mother asked me to add the chlorine.

—Then why did she send me a message at two-thirty telling me to keep a close eye on my boyfriend? —She set the shoes on the ground and looked straight at me—. What happened here?

—Nothing serious.

—Did she see you naked?

I took half a second too long to answer.

—Possible —I said at last.

—With a hard-on, Rodrigo?

I looked down.

—That’s possible too —I admitted.

Verónica stayed quiet for a few moments. Then she covered her face with her hands and let out a muffled laugh.

—I can’t believe it —she said between laughs—. My mother. My mother, Rodrigo. Hard as a rock. In front of my mother.

—It was completely accidental.

—Of course it was accidental! Who would think you’d go strip naked into my parents’ pool at two in the morning?

—You, if you knew me well.

That made her laugh even harder. She ran her hand casually over the front of my trousers, felt over my briefs, and confirmed that my cock hadn’t gone all the way down. She raised an eyebrow.

—You’re still half hard. Is it because of my mother?

—It’s because of whatever, don’t make me talk.

—Let’s go home —she said, squeezing me once more before pulling her hand away—. You can tell me everything. In detail.

***

Our friends Tomás and Natalia were waiting for us at home. They had spent the second half of the night with some friends in another town and had texted us asking if we could have one last drink together. Marcos was sleeping soundly in his room. We poured four glasses and sat around the low table in the living room.

Tomás had that characteristic energy of someone who has drunk enough to be completely uninhibited but not so much as to become incoherent. As soon as I started telling them about the pool, he folded forward with a laugh that took a few seconds to come out.

—Wait —he said, raising a hand—. When you turned around toward the switch, what did she say?

—She went quiet for about five seconds. Then her tone changed completely.

—You had a hard-on? —Natalia asked bluntly.

—Like a pole.

—Jesus.

—Silence is the worst —Natalia said—. Silence always means they’re processing something.

—Or that they’re saving the image for later —Tomás added—. To pull it out tonight while her husband’s snoring beside her.

Verónica listened with her arms crossed and a smile that never quite closed all the way.

—My mother wears glasses —she said—. Well, she used to. She had laser surgery in January and now she has perfect vision. Twenty-twenty, the doctor told her.

A new round of laughter.

—So basically you gave your mother-in-law an involuntary show —Natalia summed up, looking at me as if she could hardly believe it—. With a hard-on. In high definition.

—Completely involuntary. I’d like to underline the involuntary part.

—The most involuntary things are always the ones people remember most —she said.

Tomás lifted his glass in an improvised toast.

—To birthdays that leave a mark. And to mothers-in-law who now see twenty-twenty.

The four of us toasted.

That night, already in bed, with Verónica asleep beside me, I lay there for a while with my eyes open, thinking about Clara’s last line. Don’t be too sorry.

It wasn’t a phrase meant to downplay anything. It was too specific, too direct. It was the kind of thing that slips out when someone lets their guard down for a second, when they say what they actually think before the filter of politeness covers everything back over with normality. So were the hand on the thigh, the nipples pressing against the nightgown, the tongue appearing for a second between the lips. So was the fact that she’d sat on the edge opening her legs without panties on underneath, knowing what I would see from below.

The next morning we all had breakfast together at their house, as we usually did on Sundays. Clara served the coffee, handed out the fruit plates, talked with her husband about whether it was going to rain that afternoon and about the price of fruit at the market. At no point did she mention anything about the previous night.

Only once, when I was clearing the glasses from the table and got up to help her, did our eyes meet for a moment. It was less than a second. She lowered her eyes with measured slowness, to the exact height where the night before she had held mine for so long, then lifted them back to mine, and went on clearing up without changing pace, with the trace of a very small smile at the corner of her mouth.

I went back to my chair.

That summer was the hottest I can remember. But July still had a long way to go.
