The Night I Got Revenge on My Ex with a Stranger

Carolina had always attracted attention without trying. Since high school, her blonde hair and light eyes were enough to make people’s gazes linger on her a second too long. She wasn’t tall, and back then she had a slender body with no pronounced curves, but she never cared much. She didn’t live at the gym or in front of a mirror, and even so, she had more compliments than she knew what to do with.

It was during those years that she met Rubén, two grades above her, athletic and with that cocky, likable swagger that pulled his whole group of friends along with him. He was the one who gave the orders, the one who decided, and Carolina let herself be swept along almost without realizing they were already together.

The relationship grew in the most natural way. Rubén was her first and only experience, and over time they learned how to work together in bed. She liked sex, enjoyed it, but it was never anything extraordinary. It was fine, nothing more. He had a dominant streak that attracted her, though he wasn’t exactly an expert either. They did what they were supposed to do, finished, and that was that.

There was only one thing she never gave him: her ass.

Rubén tried many times, with caresses, with hints, with lines like, “Let me try, even just a little.” Carolina always refused, sometimes with a mocking smile, other times with a sharper “not a fucking chance.” It was her boundary, and no matter how much he disliked it, he never pushed beyond complaining.

Over the years, Rubén became obsessed with iron. His body swelled until he became a mass of muscle, and with every new kilo his ego grew too. He liked feeling strong, feeling superior. Carolina had no complaints about that, but she began to notice that he looked at himself more than he looked at her. Even so, when high school ended and she went to Seville to study nursing, they moved in together.

It was he who insisted that Carolina join a gym, repeating that “she had to take care of herself.” She resisted; she didn’t see herself lifting weights, but she ended up trying CrossFit, the only thing he was really interested in. And to her surprise, she loved it.

The changes came slowly. Her legs hardened, her waist narrowed, her abs started to show, and her ass rounded out until it took on a firm shape she had never even dreamed of before. When she went out, men looked at her without hiding it, and women noticed too.

Rubén noticed it too, of course. First he bragged about having “gotten her into the fitness world.” Then he became possessive: he couldn’t stand other people looking at her, or a trainer talking to her for too long. And in bed he started asking for the same thing again.

—Come on, with that ass you’ve got now, you can’t keep telling me no.

—Forget it, Rubén.

Carolina still wouldn’t budge. Anal sex had never appealed to her, and no matter how much he tried, he always got the same answer. What she couldn’t imagine was how close she was to everything falling apart.

***

She had never considered herself jealous. She trusted him. She didn’t check his phone or ask who he was talking to; they had been together too long to doubt each other.

But one night everything changed. She was on the sofa going over some notes from her practicum when Rubén’s phone, on the table, vibrated with an Instagram notification. She wasn’t planning to look, but her eyes went there on their own.

A private message: “When are we seeing each other again? I loved last night,” with an emoji that left no room for doubt.

She froze. She picked up the phone almost without realizing it. The profile was of a brunette girl, the kind who go to the gym just to take photos afterward. It’s probably some crazy woman messaging for no reason, she thought. But something in her stomach told her otherwise.

She slid into the conversation, her pulse racing. Messages from weeks, months. Shameless flirting, photos, meetups. There was no possible doubt. And when she opened other chats, she found the worst part: she wasn’t the first. Several names, different faces, the same story. It wasn’t a slip. It was a habit.

The rage rose through her chest like fire just as he walked through the door, careless, with his usual cocky attitude. Carolina didn’t scream. She stood up, phone in hand, and shoved the screen in his face.

—Who’s this?

Rubén barely flinched. He shrugged.

—It’s not what you think.

—Oh, really? Because I see photos, messages, I see when you met up with her… and I see there are more.

—Look, don’t exaggerate. It’s things that happened, that’s all. It doesn’t mean anything.

—You’re fucking this one and God knows how many others and you tell me it doesn’t mean anything?

—What do you want me to say? That I regret it? I’m not going to lie to you.

That was the final blow. Not one apology, not one attempt to fix it. For the first time in all those years, she saw him clearly: a gym meathead convinced he could do whatever he wanted without consequences.

—Go to hell, Rubén.

She grabbed her bag, her jacket, and her phone, and left without looking back.

***

The following weeks were horrible. She moved in with two friends from college, the only ones who knew the whole story. For days she felt stupid, used, replaced. It wasn’t just the cheating; it was that he had betrayed her while she gave him everything.

And the strangest thing of all was that she didn’t miss him. Not his presence, not his attitude, not the sex. When she thought about it calmly, she realized she had never felt the kind of madness other girls described. It had been normal, functional, and nothing more.

Her friends pushed her to go out, to move on.

—Are you seriously going to keep walking around looking miserable because of some guy who betrayed you? You’ve got an amazing body now. If you don’t take advantage of it, you’re an idiot.

At first she didn’t even want to listen to them. But the idea sank in. Why should she keep playing the faithful girlfriend when he never was?

—Fine —she said at last—. Let’s go out.

—But you’re going out looking good, not like you’re headed to a funeral. Put on that dress that shows off your ass and we’re going to own the club.

She knew exactly which dress they meant. A tight, pale-colored one that clung to every curve like a second skin and made her waist look even smaller. The kind you wear when you want people to look at you. That night she decided it was time to stop being the good girl.

***

Carolina knew she looked spectacular. It wasn’t vanity, it was the certainty that her body was at its best. The makeup, subtle, gave intensity to her gaze. She took a deep breath: she wasn’t nervous, she was expectant. When she came out into the living room, her friends whistled.

—My God, you’re going to make guys kill each other tonight.

The nightclub was packed, music vibrating through the walls and colored lights sweeping over the bodies. As soon as she walked in, eyes locked onto her. Murmurs, gazes traveling over her from head to toe. She had always attracted attention, but that night was something else.

The first guy took less than ten minutes. A tall brunette with a fitted shirt showing off his arms and a smug grin.

—With that body, tell me you don’t have a boyfriend, because that would be a crime.

—I did, but he turned out to be an asshole. So I’m free.

—Then today is your lucky night, gorgeous.

—Nah. I think I’m staying with my friends.

The guy blinked, baffled, and walked off snorting. Less than a minute later he was hitting on someone else. There were more attempts, all the same: inflated bodies, superior smiles, canned lines. Carolina turned them down one after another without hesitation.

—You look like the judge at a casting —her friends laughed—. None of them convince you?

—If it’s just for fucking, it should at least not gross me out five minutes later.

And then he appeared. Just like that, beside her at the bar, ordering a drink. A guy in his thirties, with glasses, a black shirt, and a completely normal body. Nothing muscular, nothing flashy. He wasn’t showing off, and that was already a plus.

—You don’t look like you’re having much fun —he said, glancing at her with half a smile.

—Oh, really?

—No. You’ve got the same face I make when I try to socialize with people I’m not remotely interested in.

Carolina let out a small laugh. Something about his natural ease relaxed her.

—Have people hit on you with shitty lines? —he went on.

—Plenty of times.

—Makes sense. You’re the most beautiful woman in this club.

He said it without trying to impress her, as if stating a fact. And for some reason, she liked that more than any pickup line.

—What’s your name?

—Mateo. And you?

—Carolina. I’m finishing nursing school.

—Interesting. I’m a doctor —he said, and that made her smile—. My friends dragged me here. I’m not really into this sort of thing, but look, it was worth it in the end.

He wasn’t the hottest man in the room or packed with impossible muscles, but the way he talked, his confidence without arrogance, attracted her more than she expected. When their hands brushed by accident at the bar, a shiver ran over her skin.

—You know what, doctor? —she said with a naughty smile—. I think I’m going to let you give me a more thorough checkup.

Mateo burst out laughing.

—I love my job.

She said goodbye to her friends amid jokes and promises of details, gave them the hotel address “just in case,” and left with him into the night. The breeze cooled her hot skin. They had been drinking, but not enough to be drunk. She was fully aware, fully awake.

***

The hotel was elegant without being ostentatious. The elevator rose in silence, with her leaning against the wall and him glancing at her from the side. Mateo brushed a strand of hair out of her face, letting his fingers glide just barely over her cheek, and a shiver ran down her back. Her body was more receptive than usual, more sensitive, and he noticed.

Carolina walked down the hallway, and that was when he really saw that ass moving with each step, perfectly outlined by the fabric. He turned with a smile.

—Do you always look at the girls you’re going to bed with like that?

—Only when they’ve got an ass like yours —he answered, without a hint of shame, taking a step until his breath hit hers—. And I can think of several things, but I’ll start by taking off that dress.

He swiped the card, the door opened, and she went in first. Leaning against the wall, she looked at him.

—Are you always this calm, or just with me?

—I don’t like rushing. But I don’t like wasting time either.

And he kissed her. It was the most intense kiss she had ever felt: pure hunger, pure accumulated need. Mateo’s hands went straight to her ass, squeezing it as if he wanted to memorize its shape, while he pressed her against the wall.

—What a crazy body you’ve got… —he growled against her mouth.

—Shut up and get it off me already.

He pulled the zipper down slowly. The dress slid over her breasts, her stomach, her hips, until it fell to the floor in a puddle of fabric. There she stood, in a tiny thong and heels. Mateo looked her over, asked her to turn around to see her fully.

—You’re the kind of woman who shouldn’t leave this room all night.

He took off his shirt and belt, letting her see the bulge straining against his pants. Then he turned her against the wall, pressing his chest to Carolina’s back, his hands kneading her hips and ass.

—Do you want to feel it better? —he whispered against her neck.

—I want you to stop talking and start doing it.

Mateo turned her around again and started downward: her neck, her collarbone, her breasts, catching one nipple between his lips. He kept going down her stomach until he knelt between her legs, parting them without hesitation.

—You’re soaking wet already…

She threw her head back against the wall, feeling his hot tongue move over her, suck, and glide with unhurried patience. He held her by the thighs, pinning her in place, until he felt her nearing the edge. Then he stopped abruptly.

—Why did you stop? —she complained, frustrated.

—Easy. I want your legs shaking when you come for real.

Carolina pushed him toward the bed.

—If you want to play like that, fine. Now it’s your turn.

She knelt and ran her tongue over his erection, from base to tip, before taking him all the way into her mouth. Mateo groaned, gripping her hair, guiding her. She looked up at him from below, enjoying the power she had over him in that moment.

After a while, he lifted her by the shoulders, pushed her onto the mattress, and positioned himself between her legs. He slid his fingers through her sex and found her already undone.

—You’ve been getting me worked up all night —she whispered—. You’d better do this properly.

Mateo didn’t answer. He drove into her in one go, all the way, and Carolina moaned, feeling completely full. He started pounding into her hard, lifting her legs, setting the pace. The sound of bodies crashing together filled the room.

—Let me on top —she asked.

They switched positions. Carolina climbed on top, guiding him inside her again, and started moving in circles, bouncing without restraint while he kneaded her ass and slapped her now and then, making her shiver. Then he turned her face down and lay over her, dominating her completely.

***

At some point he slowed down. He pulled almost all the way out, leaving only the tip inside, and slid a hand to her ass, stroking it brazenly.

—We’re not done yet. I want more.

Carolina understood instantly, and her body reacted before her mind did. Rubén had asked a thousand times, had tried everything, and she had never given in. But this was different. Mateo wasn’t begging or trying to convince her like a spoiled child: he was stating it, as if he knew she wanted it as much as he did. And the worst part was that he was right.

—No one’s ever been in there —she murmured—. Are you really going to do it, doctor?

—If you let me, yes. And you’re going to love it.

She arched against the bed, giving him access, yielding without words. Mateo slid his fingers in slowly, massaging, lubricating, playing with just enough pressure to make her tremble. Every time he pressed a little harder, she shuddered all over.

—Good girl… —he whispered, settling behind her, placing the tip against her entrance. And in her ear, with half a smile—: To make sure you’re a good nurse, I’m going to teach you how to give injections.

He pushed in firmly, controlled, sinking into her. Carolina let out a moan of surprise and a new kind of pleasure, her fingers digging into the sheets. It wasn’t pain: it was a different pressure, an invasion that made her tremble from head to toe.

—Easy —he said, not moving all the way—. It’s in now.

Her body adjusted little by little, her breathing getting deeper and deeper. Mateo started moving slowly, and the first thrust made her cry out.

—Feel that? I knew you’d like it.

She couldn’t deny it. The arousal, the intensity, the way he had her completely under him… it was driving her insane.

—More —she begged, her voice broken—. Give me all of it.

Mateo growled and started fucking her for real, his hands gripping her hips, going deeper and deeper. Carolina no longer worried about whether anyone could hear them or whether it sounded too dirty. She only wanted more.

—And to think you’d never given your ass to anyone —he panted, tugging her hair.

—I guess I was waiting for someone who knew how to use it right.

He laughed and drove into her harder. The pleasure carried her farther than she had ever gone. When she felt the orgasm building without restraint, Mateo slid his hand underneath and rubbed her clit, pushing her over the edge.

—Come already.

Those words were the trigger. The orgasm hit her with a force that left her breathless, her body tense, a muffled cry escaping her lips. Her ass clenched around him, and that was enough for Mateo to lose control too and spill into her with a rough groan.

Carolina collapsed onto the bed, breathing in broken bursts, washed through with absolute satisfaction. Her first time like that had been insane. And the worst part of all was that she already wanted to do it again.

***

Afterward, while he stepped into the shower, she stayed lying there, body heavy and sated, without a trace of guilt. She had never let a man take her like that, never felt so free, so uninhibited. And she had loved it.

She showered too, got dressed in the same clothes she had arrived in, though now everything felt different. When she came out, Mateo was almost ready. They looked at each other with silent complicity.

—It was a good night —she said.

—Yeah. And it might not be the last —he replied, sliding his fingers along her waist.

—You that sure?

—Let’s just say I think you still have a lot to learn.

Carolina let out a low laugh before stepping away.

—We’ll see, doctor.

She gave him one last look and left the room. No promises or complicated goodbyes were necessary. She only knew that, after that night, something in her had changed forever. And the best part of all was that she wanted to keep discovering it.
