My Aunt Asked Me for Help in the Fitting Room That Afternoon

Summer was dying slowly and, with it, the date I had spent months waiting for was approaching: my exchange year in Lisbon. I had only a few days left in the city, days split between parties, farewell hugs, and that sweet melancholy that comes before every great change. So when the phone rang that morning and I recognized my Aunt Carla’s voice, something in my chest stirred with a mix of joy and a nervousness that was already far too familiar.

—Mateo, my love —she said in that cheerful, slightly affectionate tone she always reserved for me—. Are you very busy today? Your uncle didn’t want to come with me to the shopping center, as usual. I need a dress for my niece’s fifteenth birthday. Will you take me, please?

I smiled into the receiver, already feeling my pulse quicken.

—Of course, Aunt. I’ll pick you up in an hour.

—I’m not going to steal your whole day, I promise. I know you’ve got plenty of goodbyes pending.

—I’ll be there.

What we had had always been different, closer than any other relationship between an aunt and her nephew. Ever since my mother, Renata, announced she was pregnant, Carla had felt a special affection for that child who had not yet been born. Over the years, that affection had become physical in a natural way: hugs that lasted an extra second, cheek kisses that brushed the corners of the lips, caresses on the hair or back that lingered. We were confidants, accomplices. She found in me the attention her husband had stopped giving her, and I, at twenty years old, saw in her the most desirable woman I knew.

When Carla got into the car, her warm, sweet perfume, with notes of vanilla and jasmine, filled the whole cabin. During the drive we talked about anything and everything: the trip, the classes I would be leaving unfinished, how fast time had gone by. But I couldn’t stop my eyes from drifting to the neckline of her blouse, where her generous breasts moved softly with each bump in the road, heavy and tempting.

We arrived at the first boutique. Carla disappeared into the fitting room and came out a little later wearing a tight black dress that looked like a second skin. The stretchy fabric clung to every curve: it marked the fullness of her breasts, the firm contour of her waist, the roundness of her hips. Under the lights, her nipples could be seen standing hard, pressing brazenly against the fabric.

—Well? —she asked, slowly turning in front of the full-length mirror. Her hands slid down her sides, stroking the fabric as if she wanted to make sure I would touch her with my eyes, too.

I swallowed. My cock started to harden at once, pressing against the fabric of my pants. I tried to hide it by crossing my legs, but it was useless.

She noticed immediately. Her eyes dropped slowly to my groin and stayed there, watching the bulge grow and become unmistakable. For a second a playful smile appeared on her lips; then something deeper and forbidden flared in her belly.

—It’s very tight on the chest… —I muttered hoarsely.

—Does it bother you that they show so much? —she asked with feigned innocence, though her eyes sparkled with mischief.

—No… it’s just that they’re very noticeable —I stammered, unable to look away.

Carla laughed softly, a velvety sound, and went back into the fitting room. Inside, a strange tingling spread between her legs. It’s just a dress, she told herself. But she was already enjoying my reaction more than she dared admit.

Every dress she tried on was more provocative than the last. The second, silver-gray, sank between her firm buttocks like an obscene caress. The third, an emerald-green strapless number, barely contained her breasts and showed the lower curve of her ass. I was visibly nervous, unable to hide my erection, shifting in the chair with burning cheeks.

She hesitated for a moment. She knew she should stop. But the delicious tension floating between us, that forbidden electricity, was too addictive. She had never planned it. It was simply happening.

Then, as she tried to take off the green dress, the zipper got stuck. She pulled once, twice, but the fabric was so tight she couldn’t get it off either over her head or down below without risking tearing it.

—Mateo… —she called from inside, her voice a little shaky—. Can you come here for a second? The zipper’s stuck.

The fitting room was tiny. I stepped in and pulled the curtain closed behind me. I pressed myself against her back to help her, and as soon as I did, my hard, hot erection pressed right between her buttocks, separated only by the thin fabric of the dress and thong. She let out a broken sigh. A liquid heat ran through her belly and her sex suddenly grew wet.

Without either of us deciding it, our bodies began to move. Her hips traced slow circles, rubbing against the hardness pressing into her. I answered by pushing gently, letting my cock slide between her buttocks in an electric brush of friction.

—Mateo… are you okay, love? —she whispered, her voice trembling with arousal.

I swallowed, embarrassed but unable to lie.

—It’s just… I’m sorry, Aunt. It’s because you’re so close.

Carla felt a shiver run down her spine. She turned slowly until she was facing me. The movement made my erection glide along her thigh and end up pressed against her pubis. Her generous breasts flattened against my torso, her hardened nipples brushing the fabric of my shirt.

Our faces drew closer by the millimeter. Our breathing mixed, hot and uneven. My lips almost brushed hers, but at the last instant she turned her face away, breaking the contact we both wanted with dangerous intensity.

—Wait for me outside, please… —she whispered, cheeks blazing.

When I came out, Carla stayed leaning against the wall, her heart racing. She was soaked. With trembling hands she removed her thong and bra, put them in her purse, fixed her blouse as best she could, and came out of the fitting room with a serene smile, as if nothing had happened.

***

We were walking toward the next store when I noticed the change in a shop window reflection: her breasts moved freely beneath the blouse, heavy, soft, with the nipples marked and erect. My cock throbbed painfully.

She noticed my gaze. Without saying a word, she unbuttoned one more button on her blouse, revealing a little more of the deep valley between her breasts. She gave me a naughty smile and hung on my arm, pressing her breasts against me as we walked.

—Let’s go to another boutique —she murmured—. This time wait for me near the fitting room.

In the new store, more elegant and with private fitting rooms, Carla chose short dresses that had nothing to do with a fifteenth birthday. She wanted to provoke me. She wanted to see how far I would go.

She went into the fitting room and, after a few minutes, called me.

—Mateo, come here for a second.

I went in and shut the heavy door behind me. The magnetic click echoed in the small space. Carla was wearing an extremely short, tight black dress. Her bare breasts pushed against the fabric, the nipples about to show. When she moved, the skirt rose enough to hint at her pubis, with its soft, trimmed hair.

—How do I look? —she asked in a sweet voice, swaying her hips in a slow dance.

I couldn’t answer. I stepped forward and, just as my hands settled on her hips, the fitting room lights went out with a metallic hum. The darkness was absolute. Not even the hallway light filtered in beneath the door.

—They’ll be back —Carla said, though her voice held a nervous, excited edge—. I don’t think they’re going to leave us locked in here.

We tried to open the door, but the magnetic lock seemed stuck. We knocked, made noise, but no one answered. The shopping center floor seemed strangely silent.

In the total darkness, the space became even more intimate. Every breath could be heard. The heat of our bodies filled the cubicle.

I took a step toward her. My hands groped and found her arms. Slowly, I slid them downward, tracing the warm skin of her thighs.

—What are you doing…? —she asked in a teasing voice, though she did not pull away.

My hands moved up her belly and my thumbs brushed the lower part of her breasts. Carla held her breath. She looked at me in the blackness—though she could not see me, she felt my presence intensely—and smiled, giving me permission without words.

—Should I take it off instead? Nobody can see us —she whispered, her voice rough with desire.

—Do you want to take it off? —I asked, pressing my erection against her belly.

—I asked first… —she replied with a smile I couldn’t see, but could hear in her tone.

I didn’t wait any longer. My trembling hands took hold of the hem of the dress and slowly pulled it up her body, brushing every curve. The fabric slid over her breasts, freeing them, and at last passed over her head. Carla was left completely naked in the dark.

The faint light from my cell phone, which I had left on the bench, barely managed to outline her shape: the large, heavy breasts, crowned by dark, erect nipples; the waist that widened into generous hips; the round, firm buttocks; and her swollen sex, glistening with wetness, with the soft triangle of trimmed hair.

Carla took a step and pressed her naked body against mine, still clothed.

—And now how do you think I look? —she whispered against my lips before kissing me with voracious hunger.

The kiss was immediate and fierce. Our tongues met urgently, tangling, exploring. She moaned into my mouth while her hands slid down my chest and tugged at my T-shirt to take it off. I helped her, breaking the kiss for only a second. Then my hands went back to her: one sank into her thick hair, gripping her by the nape; the other slid down her back to squeeze one of her buttocks hard, my fingers digging into that soft, hot flesh.

Carla felt my erection pressing against her naked belly and smiled against my lips.

—Oh, love… you’re rock hard —she murmured, biting my lower lip—. Is all this because of me?

She lowered her hand and opened the button of my pants with expert fingers. She pulled down the zipper and slipped her hand inside, wrapping around my thick, throbbing cock over my underwear. She took it out carefully, feeling its heat, its weight, the swollen veins pulsing beneath her fingers. It was bigger than she had imagined, and that drew a deep moan from her throat.

—God, you’ve got such a nice one… —she whispered, looking into my eyes though she could barely make me out, while she began stroking me slowly. Her hand moved up and down in a deliberate rhythm, squeezing just under the glans. Moisture glistened on the tip; she spread it with her thumb, lubricating the skin.

I lowered my head and sought one of her nipples in the dark. I caught it with my mouth and sucked hard, rolling my tongue around the hardened bud, nibbling it lightly. My free hand slid up her thigh until it reached her soaked sex. I parted her lips with my fingers and slid two inside, feeling the hot, slippery walls welcome me. I curved them inward, searching for that sensitive spot that made her arch and let out a muffled moan.

—God… you’re soaked —I panted against her breast.

—That’s how you leave me, shameless thing… —she confessed, speeding up the movement of her hand on me.

Carla knelt with feline grace on the cold tiles. Her face was inches from my cock. She looked up at me, her eyes full of desire. She stuck out her tongue and licked the base slowly, going up the entire length, tasting every inch of hot skin. She wrapped her lips around the glans, sucking first softly, then more intensely. She took me deep, centimeter by centimeter, until the head touched the back of her throat. She began to suck with a slow, wet rhythm: lips sliding up and down, tongue circling, one hand massaging my testicles and the other between her own thighs, rubbing her clit in circles.

The sounds were obscene and intimate: the wet slurping of her mouth, the vibrating moans transmitted through my cock, my broken breathing. I held her hair gently, fighting the urge to thrust hard, but she looked at me hungrily and took me deeper, until her nose brushed my belly.

—I’m going to come, Aunt… —I growled, tensing my muscles.

—Not yet —Carla whispered, taking me out of her mouth with a wet sound and standing up.

She pushed me against the wall and lifted one leg onto the little bench, opening herself completely for me. Her sex was exposed, swollen, dripping. I knelt at once and buried my face between her thighs. I licked her lips eagerly, parting them with my tongue to reach the inner ones, softer and soaked. I sucked her clit, drawing it between my lips while my tongue beat against it in quick motions. I slid in two fingers, then three, fucking her with them at a steady pace, curling them to rub that spongy spot inside her.

—Like that… suck me like that… finger me faster, love —she begged between gasps, moving her hips against my face while her juices ran down my chin.

Carla trembled, her thighs closing around my head, trapping me in her heat. Suddenly she hauled me up by the hair. She kissed me desperately, tasting her own flavor on my tongue.

—Do it —she begged against my lips—. Do it now, Mateo…

I turned her urgently, pressing her back against the wall. I lifted one leg and rested it on the bench, then placed the head of my cock at the entrance of her soaked sex. I pushed slowly, centimeter by centimeter, feeling the hot, tight walls wrap around me like a glove of burning velvet. When I was completely inside, both of us let out a long, deep moan.

—You’re so tight… —I panted, staying still for a moment to enjoy the sensation.

I started moving: slow, deep pullouts, controlled thrusts, brushing that sensitive spot with every push. The wet, fleshy sound filled the fitting room. Carla pushed back, fucking me with her hips, making her ass slap against my belly with a dry, erotic sound.

—Harder… all the way in —she asked, her voice broken with pleasure.

I quickened the pace, driving into her harder. Her breasts bounced against the cold wall. Then I turned her, sat her on the edge of the bench, and opened her legs. I entered her from the front, looking into her eyes in the dim light as I thrust in and out without mercy. She wrapped her legs around my waist, digging her heels into my ass to make me go deeper. Our sweat-slick bodies stuck together in a delicious friction; the smell of sex and desire filled the air.

Carla bit my neck, whispering in my ear in a breathless voice:

—You do it to me like no one else, Mateo… harder, love.

I lowered one hand and rubbed her clit in quick, firm circles while my cock moved in and out without rest. She trembled violently.

—Oh, love! I’m going to come! Don’t stop, please!

Her sex tightened hard around me: long, powerful spasms milking me from within. She screamed against her own arm to muffle the sound while the orgasm shook her whole body, making her juices spill around my cock, which kept moving inside her.

That pushed me to the edge. I pulled out of her with a hoarse groan, made her kneel, and came hard over her breasts and face, in hot streams that splashed across her soft skin. Carla opened her mouth, stuck out her tongue, gathering everything she could, moaning while she rubbed her clit to prolong her own pleasure.

We stood there gasping, leaning against the fitting room wall. Carla smiled, satisfied and dangerous, licking a drop that ran from the corner of her lips.

—Why did you pull out, love? —she whispered, squeezing my still half-hard cock with her hand—. I didn’t tell you to pull out…

—I didn’t think you wanted me to come inside —I replied, still catching my breath, unable to tear my eyes from her breasts.

—I’m too old to get pregnant… I don’t think that’ll happen —she said, running her tongue over her lips—. Next time, come inside me. It’s been a long time since I’ve felt truly full.

—Next time…? —I asked, surprised.

—Don’t you want to? —she smiled wickedly—. Because if not, I’ll find someone else.

I helped her stand and kissed her hard, my hands already playing with her naked buttocks.

—I want to come with you to the birthday —I said suddenly—. I’ll have to find something to wear. I don’t have a suit.

—What a good idea, my love —Carla replied, kissing me again.

A few minutes later, the lights came back with a flicker. We dressed hurriedly, trying to put our clothes and expressions back in order. Carla tucked her thong and bra into my bag, looking at me with a conspiratorial smile. We left the fitting room as if nothing had happened: she with her hair slightly mussed, me with my cheeks still burning. No one seemed to notice anything. And as we walked toward the exit, I knew my trip to Lisbon had just become much harder to keep.
