My Friend’s Sister Was My First Time on the Beach

My first full sexual experience came when I was nineteen, in a way I could never have imagined.

At university I shared an apartment with my cousin Andrés and with Mateo, a classmate who moved into the third bedroom when we needed to cut costs. Mateo was from Mazatlán and had that easy energy of someone who grew up near the sea. When summer came, the two of them invited me to spend three weeks in their city.

The first week was quiet. Mateo had to leave on a trip and my cousin and I stayed at his family’s house with no real plans. But when Mateo came back the second weekend, things shifted right away.

On Friday night he suggested going out with his sister Valeria and her best friend, Sofía. The idea was simple: beer and pizza on the beach.

Valeria surprised me from the very first moment. She was slim, brown-skinned, with a waist that seemed impossibly narrow above perfectly proportioned hips. She had on a fitted T-shirt and cream-colored stretchy shorts, and every time she walked her round ass showed through the fabric, two firm tits pushing against the cotton without a bra, her nipples just barely outlined when the coastal air brushed over her. I later learned she was twenty-four, though she looked quite a bit younger. What I didn’t expect was for her to be so serious with me. She hardly looked at me. She answered in monosyllables when I spoke to her.

We bought the beers while they picked up the pizzas. On the way back to the car, Mateo told me in a low voice that he had unfinished business with Sofía from years ago, that Valeria had told him Sofía still liked him, and that as far as he was concerned there was no problem with me getting close to Valeria. He was about to finish the sentence when they came running up with the boxes and he shut up.

We got to the beach and looked for the emptiest spot we could find, even though there were several groups scattered along the shore. The moon was full and lit the water so clearly that no other light was needed.

We opened the beers before the pizzas. Valeria, who had been quiet during the ride, suddenly started talking to me. She asked about my studies, the city where I lived, my family. I was starting medical school that year and she seemed genuinely interested, or at least it looked that way. She told me that at fifteen she had had an emergency surgery that left her with damage that would probably keep her from having children. She said it with a calmness that felt heavier than any sadness.

Mateo and Sofía went barefoot toward the water. They said they were going to see how the sea was doing.

Valeria and I were left alone. I told her I hadn’t seen the ocean in three years.

“That can be fixed,” she said, and started taking off her sandals.

I pulled my pants up to my knees and followed her.

We walked along the wet shoreline, where the sand changes texture with every wave. The moon was still up, very white, lighting everything. Mateo and Sofía had disappeared somewhere down the beach. The people left near the cars were talking less and less.

“People start doing their thing,” Valeria said softly.

Hearing that, with cold water between my fingers and her walking half a step ahead of me, gave me a shiver that had nothing to do with the temperature. I started getting hard inside my pants without being able to do anything about it.

We went into the water up to our ankles. Then to our shins. At some point a bigger wave caught us by surprise and I took her hand so she wouldn’t lose her balance. And then she didn’t let go.

We went on like that for a while, feet in the water and hands intertwined, talking about nothing in particular. Then a wave came and soaked us up to the waist all at once. We both moved at the same time looking for support and ended up with her face just inches from mine.

She stayed there. Not moving. Looking at me.

I leaned in to kiss her. But she was faster: she pulled me toward her with the hand she had free and slid her tongue into my mouth before I got there. She drove it in, thick and hot, searching for mine with real hunger, and while she did it she pressed her wet cunt against the bulge in my pants with an urgency that left no room for doubt. I felt her hard tits flatten against my chest, her nipples rigid through the wet fabric, and her free hand yanked down to grab my cock over my pants and squeeze it.

“You’re rock hard,” she whispered into my mouth, never stopping her grinding.

We stayed like that for maybe a minute, water up to our waists and the moon above us, her moving her hips against my dick as if we were already fucking with our clothes on. Then Valeria pulled away and said, with a naturalness that threw me off, that we’d better go get another beer.

As soon as we reached dry sand we kissed again. This time without water or waves. Just her against me, her slim body pressing into mine and her breathing getting faster and faster. I slipped my hands under her wet shirt and grabbed her bare tits right away. They were small, firm, with nipples so hard they dug into my palms. I pinched one and she let out a short moan that made me squeeze her tighter against me.

Little by little she started moving. A slow, rhythmic motion, as if she were dancing with my leg. I realized too late what was happening: Valeria was rubbing her cunt against my right thigh, eyes closed and mouth slightly open, oblivious to everything except that motion. Her stretchy shorts had clung to her crotch and I could feel the wet mound grinding against my leg harder and harder each time.

I focused on holding her up, on feeling the pressure of her hands on my shoulders, on that soft sound she made between her lips when the friction got more intense. My pants were far too tight for what my body wanted to do; my cock had gotten so hard it hurt against the fabric, but I didn’t move.

By force of moving, we ended up on our knees in the sand. She didn’t stop. She sat astride my thigh and rubbed her cunt up and down with her eyes half closed, leaving a wet stain on my pants that kept growing. Every now and then she looked at me as if asking whether I felt it too. I grabbed her ass with both hands, under the shorts, her skin hot and firm, and helped her move faster by pressing her cheeks against my leg.

I felt it. Of course I felt it.

“Suck my tits,” she asked me in a husky voice, pulling her shirt up to her neck.

I bent down and sucked one dark nipple, then the other, latching on hard, biting them gently with my teeth while she kept moving her hips. A gasp escaped her every time I ran my tongue over a nipple. She pulled my hair back and smashed her mouth to mine in a kiss dripping with saliva, her whole tongue inside.

She let herself fall back onto the sand with her knees bent. She pulled me toward her with one hand and with the other started hiking her shirt up over her waist. Then she made the gesture of pulling down her shorts.

I looked around. The moon was still lighting the beach from the water side. We were perfectly visible to anyone who looked.

“Here?” I said in her ear.

She nodded without speaking. She was only panting.

I helped her take off her shorts. Her underwear came off with them. Valeria’s cunt was exposed under the moonlight: shaved, shining from how wet it was, lips swollen and parted with excitement. I placed my palm over it, feeling the damp heat stick to my skin, and slid my middle finger in slowly, all the way to the bottom. She was so slick it sank in with one motion.

“Ah, like that,” she panted, arching her back.

I slipped in a second finger and started moving them inside while I rubbed my thumb over her swollen clit. She clutched the sand with both hands, opening her legs wider, pushing her hips against my hand. I kissed her mouth without stopping fingering her.

Then I heard voices.

Mateo and Sofía were coming back from the water.

Valeria sat up abruptly and yanked her shorts up over her thighs, which was all she managed before they arrived. They greeted us normally, without commenting on anything, and kept walking toward the sea.

We stood up in silence and went to the car.

Without saying a word, we climbed into the back seat.

Valeria threw herself on top of me as soon as I closed the door. I kissed her more calmly than before, but she didn’t want calm. She pulled down her shorts and underwear in one jerk while I did the same with my pants, which I only managed to get off down to my knees. My cock shot out, hard and throbbing, the tip already wet from having been held in so long.

She looked at me. Looked down. Stayed there for a few seconds staring at it and licked her lips.

“You have such a delicious cock,” she said, grabbing it with her hand and squeezing it in her fist.

She jerked it two, three times, pulling the foreskin up and down, spreading the fluid from the tip all over the head. Then, without preamble, she settled astride me, parted the lips of her cunt with two fingers and guided my cock to her entrance. I felt it slide against her wet flesh for a moment and then she dropped onto me suddenly, sinking it all the way in with a single sit.

I felt the heat first. Then the pressure. Then a burning, tight sensation I couldn’t describe because I had nothing to compare it to. Valeria’s cunt squeezed my dick from all sides at once, hot, slippery, as if she were sucking it inside her.

This is really happening.

Valeria braced her hands on my shoulders and started moving. Slowly at first, rising until only the tip stayed buried and lowering back down to the hilt, then harder, riding me with her whole hips. I tried to take her blouse off, unhook her bra, but she ignored my hands or pulled away before I got anywhere, focused on her own rhythm, on fucking my cock as if it were the only thing that existed.

I enjoyed touching her breasts over the fabric and then slipping my hands underneath to grab them bare while she moved on top of me with her eyes closed and her head tipped back slightly. I kissed her neck, licked her collarbone, sucked her nipples when she bent low enough to give them to me. Every now and then she leaned down and kissed me on the mouth, quick, as if to confirm I was still there. Every time she rode me all the way down, I felt the tip of my cock hit something inside her and it drew a long gasp from her.

I wasn’t going anywhere.

“Fuck me harder,” she asked, grabbing my neck.

I grabbed her ass with both hands and started thrusting from below, driving into her with my whole hips every time she came down. The wet sound of her cunt swallowing my cock filled the car. The seat springs creaked. The car windows began to fog. Valeria breathed harder and harder, with little sounds that stuck in my memory more than anything else from the whole night.

“I’m about to come, don’t stop,” she moaned against my ear. “Don’t stop, don’t stop, like that, there, there...”

Suddenly she collapsed onto me with all her weight, pushing down hard, and stayed completely still while something moved through her body in waves I could feel from inside. Her cunt pulsed around my cock in spasms, squeezing and releasing me rhythmically, gushing so much that it ran down my balls and onto the seat.

Then she pulled away.

She sat beside me, adjusted her shorts, and rested on my shoulder with a lightness that contrasted with everything that had happened thirty seconds earlier.

“Did you finish?” she asked.

“No.”

“Poor thing,” she said, and without further preamble she took my cock in her hand and started moving, pumping it up and down in her fist, squeezing hard, making a wet sound from everything that had been left on it from her own cunt.

She leaned down, licked the tip once with her flat tongue, and then took it all the way into her mouth. I felt the heat of her throat, her tongue circling it, her lips closing tight around the base. She sucked me hard, bobbing her head up and down, one hand keeping pace along the shaft and the other massaging my balls.

I pulled her off for a moment and she looked up at me from below, my cock resting on her cheek, and asked in a low voice:

“Do you want to cum on my face?”

It was automatic. There was no time to process the question or answer it. I grabbed her head and put it back in her mouth two or three more times, and when I felt I couldn’t hold on any longer I pulled it out and started jerking myself over her face with my fist clenched. The first rope of semen landed across her forehead and cheekbone. The second hit her open mouth and the tongue she stuck out to catch it. The rest spilled over her chin, her tits, the neckline of her T-shirt. She didn’t close her eyes even once, with more intensity than anything I had ever imagined before.

When I finished, she ran two fingers over her face, collecting my cum, and put them in her mouth, sucking them clean without taking her eyes off me.

We cleaned ourselves up with whatever we found in the car. I got dressed as fast as I could because Valeria said Mateo and Sofía must be close by now. She wanted us to get out before they arrived. She didn’t want her brother to have to confirm what he probably already knew.

We got out of the car. They arrived two minutes later.

No one said anything.

***

Back at my cousin’s house, in the middle of the night, I took a long shower. That’s when I found it: sand. In the folds of my clothes, between my fingers, in places where there should not have been sand in any possible way.

I laughed to myself under the water.

I’d been taken for a first ride without being asked, on a beach lit by the full moon, with no plan and no protocol. Valeria took what she wanted, gave me more than I expected, and the next day she had breakfast with the whole family as if nothing had happened.

Mateo never brought it up. Not that week or in the semesters we still had left sharing the apartment.

Some things sort themselves out when no one names them.
