What I Saw Behind the Tinted Glass That Night

Some time ago, my wife and I discovered something new: the idea of bringing a third person into bed turned us on, without him knowing the real game. The first time was almost by accident, without planning it. The second time we arranged step by step, down to the last detail. This is that second time, the one that ruined any attempt at marital boredom for us forever.

Carolina works part-time in her parents’ family business, a grocery warehouse that supplies half the neighborhood. She helps out when she can, receives the suppliers, signs purchase orders. One night, while we were having breakfast in reverse —she in a robe, me naked, both of us messy-haired after fucking until three in the morning, my semen still running down between her thighs— she confessed that one of those suppliers had been openly flirting with her for months.

—What’s his name? —I asked.

—Damián. The one with the cookies and the sweet bread.

—And what do you tell him?

She bit her lip. That was all the answer I needed.

That very night, while I had her underneath me and was kissing her neck, I whispered the idea to her. To give him her number. To let him be the one who worked up the nerve to propose it. To let the story write itself. Carolina didn’t say yes, but she didn’t say no either. She clamped her legs around my waist, dug her heels into my ass, and begged me in a broken voice to split her cunt open, to fill it to the bottom. I drove my whole cock into her in one thrust and she screamed against my shoulder. Each thrust tore a louder, harder “more, deeper” from her, blending with the wet sloshing of her soaking cunt. When I came inside her, I felt her pussy tighten in spasms, milking me dry to the last drop while she whispered in my ear: “I want you to do me while you’re thinking about him, I want you to fill me up imagining how another man is going to fuck me.”

***

Damián’s first message arrived three days later. Innocent, formal, using a price-list change as a pretext. The second was a joke about how tired she looked on his last visit. The third, a question a supplier should never ask: «Does your husband treat you the way you deserve?». And there I knew we were already in.

Carolina and I wrote his character together, lying in bed with the phone between us. We invented him a story: she was a forgotten woman, a husband distracted and swallowed up by work, a routine that had made her invisible even to herself. Damián swallowed the bait whole. He answered with things like «he doesn’t know what he has» and «I’d look at you every day if you were mine», lines lifted from a clumsy seduction manual he thought he had invented.

The conversations became daily. Almost always at night. I read every message in real time, lying next to Carolina, my breathing shorter and shorter, my hard cock pressed against her hip. There were nights we ended up fucking twice, imagining what the real encounter would be like. I repeated in her ear what she was going to do to him, what she was going to let him do, what she was going to allow him to believe. “You’re going to suck his cock until he comes in your mouth,” I whispered as I sank two fingers into her soaking cunt. “He’s going to get here thinking he’s the one who’s going to fuck you, and he’s going to end up making you swallow every drop of cum he gives you.” Carolina writhed, bit my neck, asked me to put in a third finger. “And you’re going to be there, seeing all of it, watching another man spread my legs open.” She climbed on top of me, took my cock in her and rode me while her tits bounced until she came three times in a row, moaning Damián’s name without realizing it.

After four weeks, Carolina invited him to our house. A Thursday at nine at night, when supposedly I’d be out with my friends playing dominoes.

We had to prepare ourselves. Our bedroom faces a side corridor that years ago was part of the patio: we roofed it over to gain space, but it remained separated from the room by a large floor-to-ceiling window. We had never given it any special use until that idea that changed everything. A week before the encounter, I called an installer to tint the glass the opposite way: opaque from inside to outside, transparent from outside to inside. The guy asked me what I wanted something like that for. I told him it was for the office. He didn’t ask again.

On Thursday I got home at seven. Carolina was getting ready. She was wearing a white silk blouse, a short black skirt that left half her thigh bare, and heels that made her ten centimeters taller. Underneath, a nearly transparent black lace set she’d shown me half an hour earlier, with a thong so tiny it barely covered the slit of her cunt. Soft makeup, lips just lightly painted. She smelled like something new, a perfume I had never seen on her before.

—Are you sure? —she asked, looking at herself in the mirror.

—I’m sure. But if you want to stop, we stop. There’s still time.

She shook her head. Her eyes were bright, her cheeks flushed. It wasn’t fear. It was something more like hunger. She lifted her skirt, took my hand, and put it between her legs. She was already wet. The thong was soaked through. She sucked my fingers after I’d wet them in her and smiled.

—I’ve never been more sure —she said.

At eight-thirty I went out the front door, walked around the block, came in through the back gate, and slipped into the side corridor. I turned off the light, sat down in a garden chair I’d left ready, and stayed there staring at the window. Inside, the bedroom was lit. Carolina had turned on a table lamp and another one from the ceiling. The bed was freshly made. The air conditioner was on low.

***

Damián texted at five to nine: «I’m outside». My heart sped up as if I were the one about to commit the infidelity. I heard the front door, the greetings, the first laughs. Carolina had let him into the living room. They talked for almost forty minutes. I couldn’t make out the words, only the tone: him low, nervous, her controlled, amused. Like a cat playing with a wounded bird.

Then I heard heels. Slowly, unhurried, crossing the hallway. Behind them came the dry sound of men’s shoes. Carolina entered the bedroom first, turned on the other lamp, and turned toward him. Damián came in behind her, with his shirt untucked, sleeves rolled up, looking around as if he were searching for an exit he couldn’t find.

He was a man in his forties. Not handsome, but careful with himself: trimmed beard, hair combed back, strong cologne. He had the nerves of a boy. Twice in those first minutes he asked Carolina about me. Where was I. What time was I coming back. My wife answered with a smile I knew well, the smile she used to win arguments.

—Don’t worry —she said—. He’s not going to show up. On Thursdays he comes back at dawn and goes straight to the bathroom.

Damián nodded, still unsure. Carolina moved closer. She put a hand on his chest, straightened his collar like a wife would, and kissed him. A deep kiss, tongue, both hands on the back of his neck. Damián froze for a second, incredulous, and then kissed her back with months of delayed hunger. He grabbed her ass over the skirt, squeezed it with both hands, lifted it against his bulge. I watched my wife rub her pelvis against another man’s erection, saw her move her hips in slow circles to feel it growing.

***

There, on the other side of the glass, with my breath held and my throat dry, I watched my wife kiss another man for the first time. It wasn’t what I had expected to feel. There was no jealousy. There was something hotter, deeper, closer to vertigo. Like watching water fall from a very high bridge and wanting to jump after it.

Damián broke the kiss. He kissed her neck, slid his hand down her back, grabbed her waist. He put his tongue in her ear and bit her earlobe. Carolina took his face in both hands and guided him to the bed. She sat him on the edge, stood in front of him, and began unbuttoning her blouse button by button, without hurry, looking him in the eyes. Damián watched her as if he didn’t know where to put his hands, his mouth slightly open and a dark stain growing in the crotch of his pants.

When the blouse fell to the floor, he leaned forward and kissed her breasts over the lace bra. He bit her nipples through the fabric until they stood hard, and Carolina let out a low, rough moan, one I knew well, one she only lets out when she’s really hot. He fumbled with the bra clasp, tossing it to the floor, and stood frozen for a second staring at her tits. Then he threw himself on them: he sucked one nipple until he had it all the way in his mouth, licked the other, squeezed them with his hands until Carolina threw her head back, closed her eyes, and buried her fingers in his hair. I could see the back of her neck, the long line of her throat, the shine of the little chain I had given her for our anniversary swaying against her chest.

I reached down to my pants without even realizing it. My cock was already hard as a rock, leaking precum against the fabric of my briefs. I pulled it out. Gripped it firmly. I started jerking off while watching another man eat my wife’s tits.

***

Damián started breathing like he’d been running. He hiked her skirt up to her waist, stroked her thighs, knelt in front of her. He kissed her belly, bit her hip bone, and shoved his head between her legs over the lace thong. I watched him run his tongue over Carolina through the fabric, watched my wife spread her legs to let him in better. Then he hooked the thong with his teeth and slowly pulled it down to her ankles. Carolina kicked it off elegantly, never taking her eyes off him. She stood there, skirt wrinkled at the waist, her shaved pussy shining in the light of the lamp, waiting.

Damián couldn’t hold back. He opened her legs with his hands, put one over his shoulder to get better access, and buried his tongue in her cunt. I watched him lick her slit from top to bottom, suck her clit with his lips, shove his whole tongue inside and shake it. Carolina gripped his head with both hands and started riding his face. “That’s it, that’s it, don’t stop, suck me like that.” Her thighs trembled. I saw the look she gets when she’s about to come: mouth open, brows drawn together, chin lifted. She came standing up, soaking Damián’s face, with a long moan that could be heard all the way to my side of the glass.

Still trembling, she knelt in front of him, unbuttoned his pants, and pulled them down with his briefs. Damián’s cock sprang free, rigid, thick, shorter than mine but broader, with a swollen purple head and a visible vein running down the left side. Carolina smiled. She licked her lips. She spit on it and spread the spit with her hand over the whole length. I saw everything through the glass as if I were watching a movie whose heroine looked a lot like my wife.

What came next was the hardest thing to watch and the most impossible to stop watching. Carolina gave him oral sex with a calm I had never seen in her. It wasn’t urgency, it was almost a ceremony. She licked the tip first, circling the head with her tongue. Then she sucked his balls one by one, taking them whole into her mouth, while she held his cock in her hand and stroked it slowly. Damián held her head with both hands, eyes closed, mouth open. When she took him all the way in, down to her throat, he let out a roar that even raised the hair on my skin. I watched the whole cock disappear into my wife’s mouth, watched the bulge form in her throat, watched the man’s pubic hair flatten against her nose. She stayed like that, swallowing him whole, holding her breath, until he tugged her hair for her to pull back. She came out with a string of saliva hanging from her mouth and smiled.

Now and then he tried to speed her up, pushing her head. She let him set the pace for a few seconds, letting him fuck her mouth, her cheeks hollowed by the suction, and then she went back to her own rhythm. She took him all the way down, brought him back up slowly, brushed him with her lips. Every so often she stopped to look up at him from below with his cock resting against her cheek, and smile at him as if she were telling him a secret. She licked the vein from bottom to top, from the balls to the tip, and took him all the way back in. Her other hand never stopped fondling his testicles, squeezing them in rhythm.

I jerked myself off in silence, holding my breath, trying not to bump anything with my elbow. My cock was smeared with precum, my hand sliding over it, and still I held back from coming. It was almost impossible. The chair creaked, the wood of the corridor answered every movement I made. But they couldn’t hear me. The double glass of the bedroom was sealed. I was invisible. I was a ghost with permission.

***

At some point, Damián lifted her from the floor. He took off her skirt, laid her on the bed, and climbed on top of her. He kissed her everywhere. He gently bit one nipple, licked her belly button, spread her legs wide open. He spit on her pussy and spread the saliva with two fingers, pushing them in up to the knuckles. Carolina arched her back. Then he settled himself upside down over her, in sixty-nine, and began to lick her while Carolina kept his mouth full of him.

I watched my wife enjoy herself like I had rarely seen her do. I watched her close her eyes, arch her back, let out a muffled moan that died against his body. I watched Damián grab her ass with both hands and squeeze it as if he wanted to leave marks, watched him pull her butt cheeks apart and run his thumb over the tight little hole. Carolina jumped, and he took it as permission. He started licking there too, alternating between cunt and ass, sucking everything, soaking her in saliva. My wife wasn’t controlling anything anymore. She was surrendered. With his cock buried down her throat and his tongue in two holes at once. She came again, her legs closed around his head, with a cry muffled by the cock blocking her mouth. And I, on the other side of the glass, had to let go of my cock to keep from coming too soon.

Damián started shaking. He tried to hold out. He clenched his eyes shut, bit his lip, tried to pull away. But my wife wouldn’t let him. She sped up, wrapped him with her legs, pulled him against her. She dug her nails into his ass cheeks so he wouldn’t move. I saw his jaw loosen, his whole body tense, his ass tighten in a spasm. I heard it even through the glass: a rough, masculine, defeated groan. He came into her mouth in spurts I could see at the corners of her lips. Carolina didn’t let go. She kept sucking while he emptied himself, swallowing every shot, moaning with his cock still in her mouth. She licked every inch of him, cleaned him, swallowed it all with that calm elegance that makes her my wife. When she finally let him out, she opened her mouth to show him that nothing was left, and closed it again slowly, licking her lips.

On the other side of the glass I came too, almost at the same time, covering my mouth with my forearm so I wouldn’t shout. The semen shot out in thick, long spurts against the tinted glass, and I was left panting with my cock in my hand, my forehead pressed to the window, watching my wife clean the last drop of another man’s load with her tongue.

***

I thought they would take a break. That he would settle on the pillow and they’d talk, smoke something, wait for a second round. It didn’t happen. Three minutes later, Damián looked at the clock on the nightstand and started getting dressed in a hurry. He said sweet, clumsy things to Carolina, the things you say to a woman when you want to feel better about leaving fast. “No one had ever sucked my cock like that.” “You’re a goddess.” “I’m going to dream about you every night.”

I guess in his head I was going to show up at any moment. That it was better not to push his luck. Carolina understood and didn’t insist. She fixed her hair, put on a robe, and walked him to the bedroom door. Before leaving, Damián picked up the thong that had been left on the rug, smelled it without any shame, buried his nose in the wet part, and slipped it into his pants pocket. He asked if they could do it again another day. Somewhere else, he said. A hotel. Whatever she wanted. And next time he wanted to fuck her properly, bury himself all the way in, fill her up.

—I’ll let you know —Carolina answered, without promising anything.

***

I waited for the front door to close. Counted to twenty. Then I came in through the back door, crossed the corridor, opened the bedroom door. Carolina was still there with her robe half open. Her cheeks were red, her hair tousled, her eyes bright, a glossy trace of another man’s cum still at the corner of her mouth. His mouth smelled was on her breath, his cologne on her neck.

—Did you see everything? —she asked me softly.

—Everything.

—And?

I didn’t answer with words. I grabbed her hair, kissed her hungrily, shoved my tongue deep into her mouth tasting the salty flavor of another man in it. I pushed her against the window, tore off her robe, let it fall to her feet. I kicked her legs apart, bent her torso against the cold glass, grabbed her hands and pinned them up against the pane. She held on with both palms open, her tits flattened against the tinted window.

I ran two fingers through her cunt and she was drenched, swollen, still throbbing from what the other man had done to her. I pushed my fingers all the way in and she let out a long moan. I pulled out my cock, hard again already, and rubbed it between her ass cheeks before thrusting it into her in one shot, all the way to the balls. Carolina screamed. I grabbed her waist with both hands and started fucking her like I never had before, with furious thrusts that lifted her off the floor, with her ass cheeks slapping against my pelvis in an obscene slosh.

—You sucked it all, slut —I told her in her ear, never stopping my thrusts—. You swallowed the last drop of another man.

—Yes —she gasped, her cheek smashed against the glass—. I swallowed everything. And I came on his face. Twice.

I gave her an ass slap that sounded like a gunshot. I grabbed her by the hair and yanked her head back. I bit her shoulder. I fucked her faster, deeper, watching our double reflection in the tinted glass: hers, panting with her tits smashed and her mouth open, and mine behind her, setting the rhythm, teeth sunk into her neck. I shoved a thumb in her ass while I kept fucking her cunt, and she came screaming, clenching my cock with spasms so strong they almost pulled me out. I didn’t last much longer. I emptied everything I had left into her, shot after shot, my forehead pressed to her nape, moaning her name. We stayed like that for a long while, her against the glass, me against her, my semen running down between her thighs and dripping to the floor. It was impossible to last after something like that.

***

Later in bed, sweaty, the lights off, with my semen and hers mixed together drying on the sheets, I asked her if she would do it again. She said yes. She said maybe with Damián again, maybe with Sebastián, the bottled-water guy, who was also sending more and more daring messages. That she would decide. That maybe next time she would let them fuck her for real, with the whole cock inside, while I watched from the corridor as another man filled her cunt with cum. I kissed her shoulder with my cock already waking up again against her thigh and stayed staring at the window, now dark, now complicit.

What happened that night lit up something we had spent years trying to name. I don’t know where it’s going to take us. I only know that that tinted window stopped being an architectural whim and became the most important place in the house. And that, for the first time in a long while, neither of us is afraid to want a little more.
