The zipper of Letícia's dress went up with a soft hiss, but the sound felt deafening inside the muggy cubicle. The three of us were trying to catch our breath, the air still thick with the blended scent of sweat, sex, and her expensive perfume. Sophia adjusted her gym top with trembling hands, her eyes gleaming with the electricity of what we had just done, while I pulled up my fleece shorts, feeling my skin still sticky from the heat.
Before reaching for the curtain to leave, Letícia paused, looking at the two of us through the mirror. A slow, decadent smile still played on her lips. She pulled her phone from her purse with striking confidence, extending it toward me.
"Put your number in here, little brother," Letícia whispered, her voice husky and loaded with second intentions. "I won't be forgetting what happened here today anytime soon. And I don't think you two will either."
Sophia looked at me, biting her lower lip with a hint of possessive jealousy mixed with pure arousal. I took the device from Letícia's hand, quickly punched in my number, and handed it back. She gave us both a slow wink, adjusted her long brown hair, and stepped through the curtain first, walking out as if she had just finished trying on an outfit.
We waited two minutes before stepping out together. Sophia held just one pair of the shorts she had chosen, leaving the other set hanging in the stall. But the moment our feet hit the corridor, the atmosphere shifted drastically.
The same sales assistant from before was standing just a few yards away, arms crossed, wearing an expression of extreme suspicion. Her eyes darted from Letícia—who was elegantly walking toward the exit—straight to Sophia and me. She took in our messy hair, our flushed faces, and our visibly heavy breathing.
"Are you finished?" the employee asked, her voice icy, dripping with sarcasm.
"Yes, we're just taking these shorts," Sophia replied, trying to keep her voice steady, but her pitch came out a bit too high from the nervousness.
The assistant took a step forward, entering the stall we had just vacated to clear out any unwanted items. My stomach plummeted. The very instant she crossed the threshold, the woman stopped dead in her tracks. The scent emanating from that tiny cubicle was undeniable: a thick, warm, heavy cloud of sweat mixed with the unmistakable, raw odor of fresh semen.
She backed out into the corridor immediately, her face flushed red with indignation, her eyes wide as she stared at us like we were criminals. Two other customers browsing a nearby rack paused to watch the scene unfold.
"Are you completely out of your minds?" the assistant raised her voice, her tone shaking with anger. "You used the store's changing room for that? You can smell it from all the way out here! This is a total lack of respect, it's strictly against store policy! I am calling management and mall security right this second!"
Panic threatened to take over. The imagery of our mother and Bia finding out about something like this made my blood run cold. I had to act fast, or our lives would be utterly ruined.
I stepped forward, completely blocking Sophia from the assistant's line of sight, and adopted the firmest, most intimidating tone I could muster, projecting a calculated coldness I didn't even know I was capable of.
"You are not calling anyone," I said, lowering my voice, locking eyes with her in a piercing stare. "My sister had a terrible drop in blood pressure in there because of the heat and our heavy workout this morning. I only went inside to keep her from collapsing onto the floor. If you make a scene or try to expose us over an accusation as disgusting as that based entirely on a 'smell,' I will be the one contacting management and a legal team for defamation. Do you really want to risk your job over a baseless assumption with zero proof?"
The assistant blinked, completely caught off guard by my aggressive, authoritative pivot. The mention of a lawsuit and losing her job made her posture of authority visibly crumble. She swallowed hard, glancing at my post-workout build, and took a step back.
"Just... go. Now," she muttered, her voice much softer as she averted her eyes.
I didn't wait for her to change her mind. I gripped Sophia's arm firmly and we walked quickly toward the exit, leaving the shorts behind. We practically broke into a run down the mall corridor all the way to the parking lot.
The moment we got into the car and I slammed the doors shut, isolating us from the world, the persona I had just put on shattered instantly. I collapsed against the steering wheel. My breath hitched, cold sweat broke out on my forehead, and my hands shook so violently I couldn't even steer the key into the ignition. The weight of that intimidating stance hit me all at once; I had never spoken to anyone like that in my life, and the realization of how close we came to being ruined left me completely unstable.
Sophia noticed the state I was in. She leaned across the console, holding my shoulder gently, her expression a mix of concern and deep admiration.
"Lucas... hey, breathe. It's over," she whispered, stroking my arm. "My God, you were incredible in there. You looked like a completely different man defending us... It was the sexiest thing I've ever seen you do."
Before I could answer to try and steady myself, my phone buzzed intensely on the center console. I looked down at the screen, my vision still a bit blurred. It was a text from an unknown number.
When I opened the app, the air left my lungs for an entirely different reason. The message was from Letícia. Beneath a short text, there was an explicit, high-definition photo, likely taken inside the store's restroom: the image zoomed in close on her shaved, flushed intimacy, with a generous amount of my thick semen slowly oozing out of her vaginal lips and dripping down toward her thigh.
The text read:
"You guys made it out just in time. That sales girl looked like she was about to explode. I can't wait to see what else you can do under pressure, little brother. Let me know when you can sneak out of the house again to fill me up like this. — Letícia."
Sophia leaned over, reading the text and fixing her eyes on the photo over my shoulder. The shock of the near-catch and my trembling were entirely swallowed by the heat that reignited the car in that exact second. We looked at each other, knowing that this stranger was now part of our darkest secret.
