The swap I planned with my cousin in Mazatlán

The trip where we were finally going to take the next step was planned with suspicious ease, as if everything simply fit together on its own. The Airbnb was the same one where Camila and I had first slept together two summers earlier, when we were still telling each other that it wasn’t going to happen again. When we arrived in Mazatlán, we stopped at a supermarket to load up on beer, meat, and everything we needed for a barbecue by the pool. I parked the car, we unloaded the luggage, and each couple went into their room to get comfortable. We agreed to meet in the living room in five minutes.

I opened the door for Lorena and, when she walked past me, I smacked her ass. I left the bedroom door slightly ajar on purpose; I wanted to hear any noise coming from Camila’s room. Lorena took her bikini out of the suitcase and started changing without an ounce of modesty. When she took off her blouse and those huge breasts fell, soft and heavy, I already had a rock-hard dick. I watched her take off the rest of her clothes and pull on a violet bikini that barely managed to hold anything in. A tiny triangle of fabric covered her shaved pussy.

I came up behind her, slipped my arm around her neck, and started rubbing my cock between her ass cheeks.

“What are you doing, handsome?” she protested with a smile.

“I couldn’t help myself,” I answered. “You’re insanely hot, baby.”

“Yeah, but they’re waiting for us downstairs.”

I didn’t answer. I turned her around, picked her up, and laid her on the bed on her back. I spread her legs and went in without hesitation, even though she wasn’t wet yet. It was something she herself had asked me to start doing. The friction of my head against her dry walls hurt her and, at the same time, sped up her pleasure. In a matter of seconds she was already wet.

She let out a muffled moan against my shoulder.

“You’re an asshole,” she whispered in my ear.

“And you’re a slut who loves getting fucked dry,” I replied, playing along.

I managed two thrusts before her fluids finished letting everything go. Her skin burned. So did mine.

“I love you, Lorena,” I told her, licking her earlobe, and I started emptying myself inside her. Her only response was to close her legs around my waist.

By the time I pulled out of her body, I hadn’t even had time to take her bikini off. I pulled the violet fabric back over her sex, still soaked. Just then Camila’s voice came from the hallway.

“Cousin, are you ready?”

I’m sure she did it on purpose.

“Yes, we’re coming down!” Lorena answered.

I put on my swimsuit in seconds and we went out holding hands.

The women settled onto the loungers by the pool while Diego and I set up the charcoal. I offered to bring beers and no one said no. I handed the bottle to Lorena and she thanked me with a soft kiss on the lips. When I passed Camila hers, she kissed me on the cheek. Up close, I noticed something: she had dry traces of semen between her breasts and she smelled like cum. The little slut had smeared Diego’s semen on herself to make me jealous.

“Well, cousin, you came dirty, you need a bath,” I said, and I lifted her up laughing.

“Mateo, what are you doing? Put me down.”

She couldn’t do a thing. We both fell into the pool, with the bottle still in her hand.

When we surfaced, Camila clung to me as if she were trying to drown me.

“You’re an idiot!” she complained, but she was laughing. Lorena was laughing too from the lounger, hidden behind huge sunglasses that covered half her face. We started wrestling and splashing around; Diego tried to smile without showing how uncomfortable he felt with the familiarity with which his girlfriend kept pressing herself against me.

“Hey, Camila, Camila, your…!” Diego stammered from the edge, pointing his finger. The three of us looked his way and then back at my cousin. One of her breasts had come out of the bikini during the scuffle.

Far from being embarrassed, Camila burst out laughing and, without stopping looking at him, took off her top with total naturalness.

“I think the sun is perfect for going topless, baby. Do you like my tits out?” she asked, directing herself to Diego. I had to bite my tongue not to answer myself.

“Uh, yes, of course, they’re beautiful, but, baby, we’re not alone…” he replied, caught between embarrassment and jealousy.

“There’s nothing wrong with it,” Lorena chimed in. “Actually, I think I’m going to take mine off too,” and she freed her enormous breasts from the violet bikini.

The look on Diego’s face would have deserved a painting.

Lorena got up from the lounger and dove into the pool with a clean plunge that betrayed her years as a swimmer. Having my two women half-naked around me had my dick at the limit, but there was still one detail left.

“Baby, leave the grill alone for a while, the charcoal still hasn’t caught,” Camila asked, swimming toward Diego’s side and stretching out her hand. “Get in with us.”

Diego hesitated for a moment and agreed. He jumped into the pool. Camila, in her official role as girlfriend, stuck to his body right away, rubbing her wet breasts against his chest. I felt a stab of jealousy that Lorena soothed by stroking my cock under the water. We spent a good while like that, playing, drinking beer, laughing nonstop. The men went to the kitchen for more beers and the women took advantage of every turn to heat up whoever stayed with them. Watching Lorena move closer to Diego and let her nipples brush his skin made me feel a kind of jealousy I didn’t remember.

I already had plenty to deal with, sharing Camila, my own blood, with that guy. But my official girlfriend, a woman with monumental breasts who at that very moment still had my semen running inside her and dissolving in the chlorinated water, was another story. Even so, it all had a purpose. In the end we grilled, ate, and moved to the living room when the sun went down behind the Pacific. The women were still topless. It was the best day of my life. There were no beers left, so I opened a bottle of wine. The two of them read the signal perfectly.

After the first toast, Camila started kissing Diego calmly and, after a few minutes, pulled down his swimsuit and left him in the same situation she was in. Meanwhile, Lorena the slut knelt in front of me and took my cock into her mouth. We stayed like that for several minutes, until I couldn’t take it anymore, lifted her up, turned her around, and sat her on top of me. She started riding me almost silently, with short, broken moans. The position was perfect for two things: while I penetrated her I could masturbate her with my hand, and the two of us had a direct view of the couch beside us.

I watched Camila flop Diego onto his back on the sofa and climb on top of him. At that moment, both couples stopped pretending we were trying to hide anything. We fucked like that for several minutes, Lorena and I watching Camila and Diego, my cousin turning to look at us with lust every so often, and Diego, who was going through something like this for the first time, his eyes closed as if he were praying. It was Camila who took the initiative: she got off him, took his hand, led him to our couch, and lay back with her legs open, drawing him in so he could enter her again.

***

It was happening. Diego started fucking Camila standing in front of the sofa, so my cousin was within reach of my hand and Diego was within reach of Lorena. I couldn’t hold back: I reached over and stroked Camila’s nipples. Diego was about to protest, but Lorena stepped in again. She took his hand, placed it on her own breast, and sealed the deal with a long kiss. Something inside Diego broke, because he started pounding my cousin harder. Lorena, remembering her wild days in college, rode me with huge bucks, soaking wet; my cock slid into her with no effort.

What came next happened with almost choreographed naturalness. Lorena lifted off me in one motion, grabbed Diego by the arm, and separated him from Camila to take him to the other couch. In the same flow, with no girlfriend of my own, it was enough for me to turn 180 degrees to bury my cock inside my cousin in one thrust, without warning. Lorena pushed Diego to sit down and, before he could say a word, sat on top of him. We kept fucking like mad until the inevitable happened.

“I love you, Mateo, I love you, cousin, I love you, I love you,” Camila shouted with every thrust.

Those words always melted me. I loved her too with a madness that knew nothing of conventions, and I considered her my woman. But in that context, with Diego unaware of our incestuous relationship, the alarms went off immediately. Lorena must have noticed that he was losing rhythm, because for the third time she saved the situation.

“Do you like my tits, daddy? Eat them, asshole,” she ordered, slamming her breasts into his face. Diego focused on his own business. I focused on mine.

We spent another good while like that. Lorena moaned at the top of her lungs and I took advantage of it to whisper all kinds of obscenities in my cousin’s ear.

“I love you more, cousin, you’re my woman, my slut, and my goddess. Do you want me to fill you with milk?”

“Yes, daddy, yes, fill me with your seed. I want to have your children, I want to marry you,” Camila answered on the edge of orgasm.

I’m sure Lorena and Diego heard it, but they were also too busy enjoying themselves. Diego soon understood that the kind of woman he was fucking, without a condom, was something he wasn’t going to get to enjoy many more times in his life. I adored Camila, just the memory of her smell got me hard, but, being honest, Lorena was a woman anyone would kill for.

Huge breasts, a round ass, honey eyes, full lips, brown skin, a tight pussy, and tons of experience. Diego was also having the best day of his life fucking my girlfriend. He’d better keep his mouth shut while I enjoyed my cousin as I felt I had every right to by birth.

I started feeling myself about to cum. I warned Camila with a dull growl that also reached the other couch. Camila dug her nails into my ass to keep me from pulling out; she didn’t care that her boyfriend was three meters away, my load belonged to her. Lorena, for her part, worked her magic on Diego: she tightened her vaginal walls around his cock to speed up his finish. I don’t know how many times she had done that before; in college she was known for a reason. When he was about to ejaculate, Lorena pulled his cock out, jerked him off with her hand, and made him finish on her own belly, avoiding any risk.

When I started emptying myself inside Camila, she covered my mouth with her hand so there would be no audible evidence that I was filling her cunt with cum. I didn’t stop thrusting until I was sure everything had stayed inside. I collapsed on top of her and whispered a shy “I love you” in her ear. Both couples stayed there for a minute, enjoying the afterglow.

After that, Diego’s embarrassment over having sprayed Lorena took over, and he ran to the bathroom to get paper to clean her off. Camila took advantage of the distraction to cup her palm under her sex, collect the excess cum, and put it in her mouth before he came back. Diego returned, wiped the naked belly of my girlfriend clean, and sat down confused on the couch. Camila, going back to her role as the good girlfriend, went over to hug him. Lorena came back to my side.

The four of us put on our shorts and bikinis, but the women left their breasts uncovered. I opened another bottle of wine and poured four glasses. Each couple very close together. The living room smelled like sex: semen, sweat, and secrets that no one was hiding anymore.

After the second glass, the mood loosened up. We started talking about the encounter as if we were analyzing a movie. I described to Diego what Camila’s nipples tasted like, and he, in turn, described in almost technical detail the pressure of Lorena’s vaginal walls. Camila talked about the texture of my head, and Lorena was very precise in narrating Diego’s ejaculation. We celebrated every conclusion by clinking our glasses together.

***

It was time to sleep. We said goodbye in the living room before each couple went into their room. I gave Camila a soft kiss on the lips. Lorena and Diego said goodbye with an apparently friendly hug, with my girlfriend’s hand brushing his cock in a subtle movement.

In the room, Lorena went in for a quick shower. When she came out, I was waiting naked and with a monumental erection. I didn’t give her time to react. I threw myself at her full of lust and something more. Even though I had allowed another man to touch her, I was infinitely grateful that she hadn’t let him finish inside her. I had to mark my territory. I threw her on the bed and went into her again before she could get wet, brushing her dry walls a couple of times with my swollen head.

“I love you, Lorena, you’re mine, you’re my woman, my slut, and my goddess,” I repeated without whispering. “I don’t want anyone else inside you, only me. I want to fill you with milk, knock you up, and marry you.”

I said it knowing that Camila had let Diego finish inside her several times “to keep up appearances,” while Lorena, the girl no one at the university had ever known how to appreciate, had shown, even under those circumstances, ironclad loyalty to me. Camila had been years of madness, happiness, and heat. But the love of my life, now that we were about to graduate, was that brown-skinned woman with the huge breasts.

“I love you, asshole, that was all I wanted to hear. Today I didn’t take the pill thinking about you. I wasn’t going to let anyone else get me pregnant. You know what to do.”

That sentence gave me a new clarity. I came so much inside Lorena that I think I lost track for a few seconds. When I came back to myself, I was wrapped around her breasts, my cum slowly leaking out of her sex, and she was stroking my head with an almost maternal tenderness.

“I’m ovulating, Mateo. It all depends on you.”

We fell asleep wrapped around each other. In the middle of the night I woke up hard again, fucked her dry again, and poured the remains inside her, which in her sleep she received with the same love.

***

The next day we went back to the city. The trip back was cordial and conspiratorial. We returned to our routine for a few weeks, until I got two identical and, at the same time, opposite pieces of news. Lorena and Camila were pregnant, and I was responsible for both of them.

Lorena’s baby was unquestionably mine. I had witnessed how she prevented Diego from finishing inside her. As for Camila, she explained it to me later: that night Diego didn’t completely hold out, and a few weeks later, when the test came back positive, she looked for him and made sure he came inside her “to keep up appearances.” Her baby was mine too. My wildest fantasy had become truth: I had gotten both women in my life pregnant.

Lorena and I got married a month later, before she started showing and could still wear a dress in front of her family. Her father took years to forgive me; in the end, seeing my devotion, he made room for me at his table. Camila married Diego a few months before giving birth, in an elegant wedding paid for by his family. Lorena and I attended as just another young married couple and no one suspected a thing.

My children were born two weeks apart. With Lorena I had a boy. With Camila, a girl. My mother, who is paranoid by nature, suspects the paternity of her second cousin, but keeps her theories to herself: on paper everything is in order. Camila and Diego are godparents to my firstborn and we returned the gesture by sponsoring the girl who has my eyes.

Every year we go back to Mazatlán to relive that weekend. Lorena is a loyal woman and doesn’t let anyone else finish inside her. As for Camila, my adored cousin, my first love and the mother of my second daughter, she will never be able to deny me filling her with semen. That’s why I love her, and I’m going to love her for the rest of my days.
