Her Trainer Offered Him an Off-Menu Class

It was Tuesday, half past six in the morning, and the gym in the new neighborhood still smelled of fresh wax and citrus disinfectant. The LED lights in the ceiling hummed softly over the empty machines. On the mirrored wall at the back, the motivational posters reflected in duplicate, and a round clock marked off the seconds with a ticking that sounded louder at that hour than at any other.

Yarisa Beltrán, twenty-eight years old, was the personal trainer with the longest waiting list at the center. Caribbean, dark skin shining under the white lighting, a mane of long braids pulled back into a ponytail so tight it sharpened her cheekbones. She wore a black sports top stretched over her breasts, plum leggings that sculpted her hips, and pristine white Adidas sneakers. On her side, just below the last rib, she had a tiny tattoo that read “Without Permission.” When she moved, the gold hoops in her ears chimed against her braids.

Her Tuesday client was Adrián, thirty-five, an executive at a pharmaceutical company, single after a long breakup that had left him with more pounds and more anger than he admitted. He had come back to the gym to get something back, without really knowing what. He always arrived on time in a gray T-shirt, blue shorts, and headphones around his neck that he never used. Since the third session, Yarisa had noticed what happened under those shorts when she put her hands on his hips to correct a squat, or when she pressed her chest to his back to adjust the glute bridge.

That morning, Adrián came in five minutes earlier than usual. She smiled at him from the leg press and pointed to the mat with a gesture of her chin.

—Warm-up. Twenty minutes today. I want to see muscles awake.

She worked him in silence. He watched her in the mirror when he thought she wasn’t noticing. The truth was that she always noticed.

When they got to the leg press, Yarisa leaned in to adjust the position of his feet on the platform. Her hip ended up a hand’s breadth from his face. The silence of the empty gym amplified everything: the rustle of fabric, Adrián’s broken breathing, his pulse, which she could guess from the vein in his neck. When she straightened, her gaze dropped without meaning to to her client’s lap and found exactly what she expected.

—Ay, papi —she said softly, with that Caribbean cadence that dragged the s’s—, what is that? So early on a Tuesday and you’re already like this?

Adrián blushed to the ears. He groped for the small towel awkwardly.

—Sorry, Yarisa, really… I don’t know what…

—Don’t apologize —she cut in. She straightened fully, took a step, then another, until her top brushed his T-shirt—. It doesn’t bother me. On the contrary.

She lowered her voice until it became a whisper almost in his ear.

—You know what? Today I’m going to give you a different class. One that isn’t on the price list. I only give it to students who behave very well… or very badly. You decide which of the two you are.

She ran the back of her hand over the top of his shorts, slowly, as if measuring him. Adrián closed his eyes.

—Do you want the class, papi?

—Yes —he answered, his voice rough—. I want the class.

Yarisa grabbed his wrist and pulled him toward the locker-room corridor. At that hour the women’s room was always empty, and she had the owner’s key copy just in case. She pushed the door open, hauled him in with a yank, and shot the bolt.

Dim lights. The smell of vanilla from the air freshener. Long wooden benches, gray lockers, and, at the back, a row of showers separated by opaque partitions.

—Take everything off —she ordered—. We’re not in a hurry, but we’re not going to waste time either.

Adrián obeyed with clumsy fingers. T-shirt, shorts, briefs. When he was naked, she raked him from top to bottom without hiding it. His cock pointed at the ceiling, the tip shining.

Yarisa pulled off her top in one motion. Her breasts, large and firm, swayed freely. She tugged down the leggings and the black undergarment in one pull and kicked them aside with her sneaker. Her shaved pussy was already shining with its own wetness.

—First lesson —she said—. Learning how to eat.

She pushed his shoulder until he sat on the bench. She lifted one foot beside him, presented her open sex a few inches from his mouth, and grabbed the back of his neck.

—Tongue. Slow at first. I want to feel you learning.

Adrián slipped his tongue between her parted lips, licked from bottom to top, slow, gathered the moisture, and kept going up to the swollen clit. Yarisa grabbed his braids with one hand and his head with the other; she set the pace. He sped up, sucked, circled her clit with his tongue in smaller and smaller loops.

—Like that —she panted—. Get your fingers in. Two. Curve them forward. Where the wall feels spongy, there. That’s it. Stay there.

Adrián curved two fingers inside her, found the spot, pressed. Yarisa’s hips began moving against his face, against the fingers, without stopping.

—Three fingers. Open me. Keep licking. Don’t stop even if you hear me scream.

He slipped the third finger in. Her sex contracted around him, hot, tight, alive. Yarisa clenched her jaw and let out a deep grunt that started in her chest. One long spasm. Another. Hot liquid wet Adrián’s chin and neck. She held his head pressed to her body until the last shudder, and only then did she let him go.

—Good student —she murmured. She brushed her thumb over his wet chin and brought it to her own mouth—. Second lesson.

She pulled him up from the bench, turned him around, and pressed him against the row of cold lockers. Then she bent over herself, hands on the metal, spread her legs, arched her back, and offered him her sweat-slicked ass and back.

—Now you’re going to put it in my cunt. All of it. In one go. And you push like you want to leave a mark on me.

Adrián took her by the hips, lined himself up, and drove into her all at once to the hilt. Yarisa gave a long, hoarse, open moan. She rested her forehead against the locker metal.

—Hard. Hard, papi. Don’t be shy.

He fucked into her hard, his hands dug into those wide hips, the sound of thighs slapping echoing between the tiled walls. Yarisa’s breasts pressed against the metal with each thrust, her nipples grazing the cold iron. She pushed back to meet him, shouted instructions at him —faster, deeper, let me feel everything— and then, suddenly, grabbed his hand and brought it to her clit.

—Now rub. Small circles. Don’t stop while you keep fucking me.

Adrián rubbed with two fingers, his thumb following the rhythm of the thrusts. Fifteen, twenty seconds were enough. Yarisa came apart completely, the inner walls clamping down on him in a way that was almost unbearable, and she let out a cry she had to smother against her forearm so as not to alert the sleeping gym.

—Keep going —she panted when she caught her breath—. Don’t come yet. Third lesson.

She pulled away. Then she got down on her own knees on the locker-room floor, over a folded towel, hands on the bench, ass in the air, and turned her head to look at him over her shoulder.

—Spit on me and put it in slowly. In my ass. I want to remember you all week.

Adrián spat on the back of her hand and rubbed it over the tight hole. He lined up the tip. He pushed millimeter by millimeter, holding his breath. Yarisa’s body opened little by little, resisting, giving way, resisting again. When the head went all the way in, she exhaled, long and slow, and pushed back to take the rest.

—Stay —she said—. Let me get used to it.

He stayed buried all the way in, his hands trembling on her narrow waist. When he felt her hips start to sway, he moved. Slowly at first, then with confidence, then with everything he had left. His left hand yanked her ponytail back to arch her spine. His right hand went back to her clit.

—Fuck —she groaned—. Fuck, fuck, fuck. Don’t stop. Make me come again.

She came against the bench, her legs trembling so hard that he had to hold her by the waist so she wouldn’t collapse. Yarisa’s whole body pulsed around him, swallowing him, milking him. Adrián held out as long as he could and, when he knew he couldn’t hold back anymore, she felt it before he did.

—Pull out. Come here.

She let him go, turned quickly, sat back on her heels in front of him, and opened her mouth. Tongue out, black eyes lifted.

—Paint my face, papi. Finish the lesson the way it’s supposed to end.

Two wrist flicks were enough. Adrián came in long spurts over her cheeks, her nose, her lips, and her braids. She stayed still, taking it all, and only then did she run her tongue along the corner of her mouth and swallow what had fallen inside.

—So good —she murmured—. You came so good.

She stood up calmly. She gestured toward the row of showers.

—Come on. You clean up, get dressed, and go to work like nothing happened. And next week, same day, same time, you come to your normal session, behave yourself, and if you convince me, we’ll do it again.

Adrián nodded wordlessly. They went into the first shower together. Hot water fell over both of them at once, steam filling the enclosed space, washing the remnants of the last hour down the drain. Yarisa soaped him with a small towel, ran her thumb over his lower lip, and smiled slyly.

—Admit it, papi —she said softly—. Tell me you didn’t expect it.

He let out a short laugh, rough, almost disbelieving.

—I didn’t expect it.

She kissed his forehead, stepped out of the shower first, dried off without haste, got dressed, and gathered up her wet braids. Before opening the bolt, she looked at him from the doorway.

—One more thing. This doesn’t get told. Not to your best friend. Not to the mirror. What happens in my locker room stays in my locker room. Understood?

—Understood.

When she stepped out into the corridor, the gym was beginning to fill up: two guys from the eight o’clock shift, an old woman with a cane, the cleaner dragging the bucket. Adrián took his bag, crossed the room with his eyes down, and pushed open the street door. Outside, Tuesday morning had already turned on the traffic lights, the cafés were serving breakfast, and buses were growling uphill.

He walked up to his office, his muscles still vibrating and a taste of vanilla and salt stuck somewhere on his tongue. In the reflection of a shop window, without meaning to, he looked at his face to see whether anything showed. Nothing showed. And yet, something had changed forever that morning. Three months later, he still hadn’t been able to tell anyone.
