The Night My Sister-in-Law Got Into My Shower

That night there was something strange hanging in the air, a current that never quite landed. Lucía arrived from Montevideo to spend fifteen days with us in Quito, where I had settled for work. I run several companies and my routine is tied to the diplomatic circuit. My wife, Marina, had caught the eye of a Central American embassy official and had been working as his assistant for months. That night, when Lucía left her suitcase in the guest room of our apartment in La Floresta — facing the park, with the mountain range peeking over the rooftops — Marina asked me to go buy her a few things she was missing for a work trip as well with that official we’ll call Esteban.

While I grabbed the car keys, Marina asked her sister to come with me, to take the chance to get to know the neighborhood a little. Lucía came down with me in the elevator with that quiet tension we had already felt before, on visits to Montevideo and on a couple of cruises we shared years ago. When I started the car I told her she was more beautiful than ever. Her face was tired from the flight, but the smile that slipped out betrayed her. She brought her index finger to her lips, smiled at me, and I drove toward the lights of the avenue without saying anything else.

When we got back to the apartment, Marina was already ready. It was almost time for her to leave for the airport with Esteban, on an embassy plane bound for Santo Domingo. I didn’t catch the murmur between the sisters in the room, but as I passed by I saw Marina putting something away in the drawer of the bedside table. While they got distracted looking for something in the closet, I leaned in. They were birth control pills, hidden under a book. It surprised me, but I said nothing.

We took her to the airport, the three of us. Marina was wearing a neckline that left exposed the shower of freckles that falls between her breasts, still firm at fifty. Her bare back made it obvious she wasn’t wearing a bra either. When Esteban appeared in the international area, he took her by the waist and whispered something in her ear. Marina looked at me, smiled, and exchanged a conspiratorial glance with her sister. I didn’t fully understand what was happening, but I felt — with an unsettling clarity — that that night I was going to end up being a cuckold.

We drove back to La Floresta in silence. The BMW felt small, filled with things neither of us dared to say. My wife was surely already settling into her first-class seat beside Esteban. Lucía adjusted her neckline as if she knew every movement of hers was sticking a pin into me. Her nipples pressed against her blouse, and my bulge against my pants. We were conjugating a passion in silence. No doubt about it.

We got there. As soon as I walked through the door, I locked myself in the shower. It hadn’t been five minutes when, with my eyes closed under the water, I felt the bathroom door open just a crack. It was her. She was spying on me without making a sound. As if inviting her, I started masturbating slowly with my soapy hand until I got hard. It didn’t take long. Lucía came in, almost naked — just a thong and the sandals she hadn’t taken off — and pressed her nipples against my back.

—Stay still and let me take you —she ordered.

I closed my eyes again.

She started by kissing my back while her mouth moved down my spine. Her hands followed the path with slow caresses. I rested my palms on the wet marble when I felt her fingers spread my ass cheeks and her tongue begin to trace my sphincter. The sensation was electric. I felt my cock, already fully erect, taken in her other hand and stroked slowly. In one move, Lucía slipped under my legs. I spread them wider so she could kneel, and she started sucking me off with an aggressiveness I hadn’t expected.

—Don’t you dare come —she ordered.

The water fell over her shoulders and lit up her breasts. Her nipples gave away how turned on she was, hard as stones.

—Were you going to leave me hot all night, Tomás, or did you expect me to masturbate myself?

I threw my head back under the spray, grabbed the back of her neck, and shoved her to the back of her throat. I made her gag and let go. She straightened up against my body, and my glans brushed the wet satin of her thong. We kissed with an old, contained fire. I wrapped my hands in her blond hair and kissed her with rage.

—At last you’re mine —she said against my lips.

I held her face and looked into her green eyes. We confirmed the sin there, in the shower, while I —with or without guilt— thought about Marina.

Soaking wet, without breaking our mouths apart, we threw ourselves onto the bed. A game of filthy kisses began, of clumsy hickeys. I ended up on my back, my erection pointing at the ceiling, and Lucía started dragging her nipples along my legs from my feet upward. When she reached my cock, she began to suck me again, with a calmer rhythm than in the shower. More calculated. She stroked me with her free hand, hard, while holding my gaze.

—I want all your cum in my throat —she told me.

She didn’t even finish the sentence. I started coming in spurts while she, without letting go, kept sucking and swallowing. She looked at me from below and let a mixture of saliva and semen fall onto my stomach. She still had the thong on, soaked through, dripping over my legs.

Now it was me who needed to strip her. To eat that cunt I had imagined so many times while fucking her sister. Every time I was with Marina, somewhere in my head Lucía appeared.

—Are you going to fuck me? —she seduced me, looking at me.

—What other option do I have?

—Your wife is fucking her guy right now too.

She didn’t let me answer. I looked at her hard and shut her up with a biting kiss, as if wanting to erase what she had just said. She lay back on top of me and I stroked her back. The thought of Marina naked on top of Esteban, in a Caribbean hotel room, turned me on more than I was willing to admit. I yanked off her thong and saw that she was completely shaved, just like her sister. She settled over me, parted her lips with two fingers, and took all my heat inside her in one single motion. She moaned long and muffled.

Lucía rode my stomach, rubbing her clit against me, crying out a jagged orgasm. I had to clench my teeth not to come too. I wanted to fuck her the way I had dreamed so many times, for years.

—Turn around, bitch —I told her.

She offered me her ass, put a pillow under her waist, and turned her face to look at me. The thong was gone, but the elastic mark was still visible on her skin. She bit her lips.

—Fuck me in the ass —she asked.

I pressed the tip against her sphincter, with the last bit of soap still on our skin, and penetrated her to the hilt. She opened herself with her hands to receive me and started moaning with her mouth open, without restraint. I fucked her with years of stored-up hunger. At last I was fucking Lucía. Or she was fucking me. I wasn’t sure anymore.

We sat up without my cock leaving her ass. We kissed again. I held her breasts with both hands and felt the caramel-colored nipples between my fingers. We passed saliva from one mouth to the other.

—Fuck me harder, stud —she told me.

I pumped into her with more force, slamming against her buttocks, while lifting her from the waist to go deeper. But I didn’t want to come yet. I let her fall onto the wet sheets. Her cunt was drawn like a perfect line between her thighs, shining. I rested the glans lightly between her lips and slowly separated them.

—Fuck me, Tomás, make me yours too —she said, and the phrase sounded like she was asking me for the same thing her sister was asking Esteban for in another bed.

—Fuck me and leave your cum inside me. I want you for myself tonight. I want to feel your heat in my insides.

—Are you sure? —I asked her in a whisper.

I kissed her forehead, her cheeks, her eyelids. I felt absurdly in love with my sister-in-law at that moment.

—Yes —she answered.

We closed our eyes, held each other, and melted into a slow, long orgasm, without the urgency of before. We were no longer fucking madly. Something had changed in the look in our eyes. I let everything spill inside her, without pulling out. Her hands held my face and she kissed me with a tenderness she hadn’t used all night.

—I’m coming, I’m all yours —she told me, and kissed me again.

When I woke up, Lucía was wearing my wife’s electric-blue nightgown, the one that barely covered half her thighs. She was serving me breakfast in bed. I couldn’t quite believe it. She looked me in the eye.

—I love you, Tomás. I can’t hide it anymore.

—So what do we do now? —I asked, pulling back the sheets and showing her that I was hard again.

—I’m going to share you with my sister. We’re going to be three in this madness. It’s already decided.

She started again with soft kisses, going down over my pubis until she swallowed me whole. She settled into a perfect sixty-nine on top of me and the morning passed in that. I don’t know how many times I came inside her, or how many orgasms she cried out, while she scratched my back until it was covered in red marks.

—Every scratch is so my sister can see you were mine these days —she said, breathless.

I kissed her, biting her lips, already swollen from so much filth, so Marina would see the marks too. I held her from the waist and pinned her against the bed until she cried out the last orgasms as if wanting her sister, thousands of kilometers away, to hear them.

The week passed quickly and at the same time with the weight of eternity. We behaved like a newly in love couple, like two lovers without a past. Lucía slept every night naked in the marriage bed, with me, her legs tangled in mine, our scents mixed, our embraces confused between two tired bodies.

Every night we left new traces on the sheets. Lucía, meanwhile, kept taking the birth control pills Marina had left hidden for her in the bedside table drawer. That was where the game came together: two sisters who had decided to share me. One went off with her lover to Santo Domingo, the other stayed with me in Quito. And the pills had been the only silent instruction between them.

When we went back to the airport to pick up Marina a few days later, I saw them before they saw us. Marina threw her arms around Esteban’s neck in the international departures area and they kissed with open mouths, not even trying to hide it. As Lucía and I approached, I also saw my wife stroking her lover’s bulge over his pants, and he stroking her Caribbean-tanned back.

Lucía looked at me conspiratorially. She gave me a little kiss on the lips and showed me her phone. She had photos. Marina naked on some beach, her breasts pink in the sun, her nipples between Esteban’s lips. And a video too. Marina fucking in a hotel room with the same guy she was now saying goodbye to with kisses in front of me.

—It’s all done —Lucía whispered in my ear.

Marina, clearly, had also been cheating on me. But when she saw me, she smiled. She blew me a kiss from far away. And when she noticed that her sister and I were holding hands, she wasn’t surprised. She returned Lucía’s greeting with a wink, as if to say thank you.
