The August boardwalk was a sultry wall of heat and chaos. We walked at a snail’s pace, trapped in the flow of a summer-loving crowd, while the bass from the beach clubs made the air vibrate. Amid all that brazen, exposed skin, Alexandra—twenty-seven, with an almost girlish appearance—seemed to almost want to hide.
She had chosen to leave her long, dark hair down and wore a light, ivory cotton sundress with a tiny blue floral print. The dress had delicate spaghetti straps and flared just above the knee, something she hoped would let her blend in. The bodice hugged a petite torso, with small shoulders, a delicate neck, and firm breasts that barely filled an A-cup. Beneath it, though, the thin fabric couldn’t hide her hips and a beautiful, rounded backside: a lush contrast to her frame, with long, shapely thighs that I loved watching move with her every step.
I squeezed her hand twice, catching her attention with our usual signal. She looked around, searching for the target I had spotted, the one I knew would catch her eye. She spotted her instantly, about thirty feet ahead of us.
She seemed a few years younger than Alexandra, with pitch-black hair tied high in a sleek ponytail. She wore a black bodycon micro-dress, so short and tight that with every stride in her high heels, it rode up, exposing her tanned skin. She walked with a deliberate confidence, swaying her hips as if the street were her personal runway. She knew perfectly well that every eye was on her.
“Look at that slut,” Alex whispered in my ear, letting out a soft laugh. The words tumbled out, with the irreverent tone of teenage boys hanging out and checking out girls.
I played along, enjoying her boldness. “Quite a view. Look at those legs,” I replied in a low voice.
“And that ass!” she chimed in, her eyes locked onto the tight black dress. “Look at the way those heels make it sway ... I really want to see her face.”
We fell into step behind her, moving discreetly and blending into the crowd, taking our time. Every now and then, we whispered another comment about the girl, noticing how her curves shifted under the dress, and how she was chatting away with her small group of friends. We wondered what she liked to do in bed, and when the last time she’d done it was. Alex elbowed me, giving me a knowing laugh.
“How often do you think she does it?” she asked me, but foot by foot, the dynamic was shifting: the jokes were thinning out, her tone becoming less playful and much warmer.
“I wonder how she moves when she comes...” she told me after a rather long silence, her voice a little raspy.
Then, as if remembering to keep up the playful facade, she let out a quick chuckle, but it was short, forced: a mechanical reflex that was becoming harder and harder to produce. She was literally devouring her prey with her eyes, pouring every ounce of her energy into it.
Then, the group of friends stopped and turned around. We kept walking straight ahead, moving toward them through the flow of the sidewalk, until we crossed paths just inches apart. Alexandra’s stride broke rhythm for a fraction of a second, slowing down imperceptibly.

The girl walked on, laughing and winking at her friends, with a playful, deliberately sexy confidence. The low-cut, tight black dress showcased her plush breasts—probably a full B or C cup—evidently braless, clearly showing her cleavage and the way her underbust bounced with every step. I felt Alex stiffen as her gaze, in those brief moments, shifted from the girl’s face straight to that specific detail, before lingering on the smooth skin of her legs as they passed us, leaving a trail of sweet perfume in their wake.
Alexandra waited a moment before turning back with me, keeping a low profile. But the laughter was completely gone now. Her shield of irony had shattered after taking in those final details: the exposed breasts, the heavy makeup, the voluptuous lips.
“I knew she had the face of a hooker, too,” Alex muttered.
All the playfulness had drained from her voice. It was now heavy with a new urgency, almost trembling from the sheer intensity of the attraction. As always, she retreated into cruder language the stronger the attraction grew, as if to prove to herself that a carnal urge had nothing to do with who she really was.
We kept following her from behind, but the laughter was completely gone now. Silence had fallen between us. I could feel the tension in Alex’s arm, the feverish grip of her fingers. We weren’t playing anymore: we were feeding the obsession.
“Look at that slut...” Alex repeated after a long silence.
I noticed it was the exact same phrase from the beginning, but this time uttered without any ironic safety net, dropped into the dim light with absolute seriousness, a hint of desire in her voice that died out with a soft sigh.
Suddenly, the girl and her friends veered sharply toward the brightly lit entrance of a noisy club, vanishing into the crowd. The prey had slipped away. Alexandra froze on the sidewalk, motionless, her wide eyes staring into the void past the people swarming in and out of the venue. I stopped right beside her, while the flow of the crowd kept streaming past us, indifferent. Alex stepped closer to me. Her breathing was shallow, her gaze fixed, still lost in that tight black dress.
She pressed herself against me, her shoulder tight against mine, and whispered in my ear in a barely audible voice: “She left me so horny ... I can’t take it anymore. I need to come.”
