The Gym
After being left in a mess at Professor Choi's villa, Su-hui felt as if something had changed within her. Just the thought of being drenched in semen was enough to ignite her body, leaving her feeling thoroughly aroused as though in heat.
*Haaah… My body… Why is it like this…*
Even though she was alone at home, her body would flare up uncontrollably at any moment. She had masturbated multiple times, rubbing her pussy until it felt satisfied. Now, Su-hui's pussy was so sensitive that even imagining it could make it slick and wet. That very day, while alone at home, she had been fucking her pussy with a dildo. The dildo, wrapped in a condom, slowly vibrated and thrust deep into her pussy.
—whir whir
—throb… throb
*Haaah…… Aaaah…. Uh…*
The condom covering the dildo was gradually soaked with her juices, and its speed increased. Soon Su-hui's pussy tightened, her lower body trembling uncontrollably. She continued moving back and forth on the dildo without slowing its rhythm. Moments later, her body convulsed irregularly as she pulled the dildo out. Juices squirted from her pussy.
*Haaah… Again… I've done it…*
Every time her pussy got wet, she masturbated. So Su-hui ended up masturbating several times a day.
“I can't stand it anymore…”
She decided to relieve her overflowing sexual desire through exercise. If she moved until her body was exhausted, she wouldn't have the strength to masturbate and would simply fall asleep without it. Of course, there were trainers at the gym who had sex, but…
*Still… It's daytime…*
Since it was during the vacation and off-peak hours, she could quietly exercise among the people.
*Well… It doesn't matter…*
And… Since she was doing this, rather than masturbating alone, she figured it wouldn't be bad to be toyed with and fucked by a trainer's muscular body. Thinking this way, Su-hui's pussy grew even wetter.
*Ahh… Again…*
Su-hui's white fingers slid into her pussy.
—————
After freshening up, Su-hui prepared to go to the gym. It was still winter, so she packed leggings and a sports bra for the trip. Upon arriving at the gym, as expected, it was bustling with people. In the changing room, she changed into her workout clothes, tied her hair up, and came out. Her body, honed by sex and exercise, was slim and toned. The dark navy leggings that showed her slender leg lines and the sports bra that barely covered her breasts exposed her narrow waist and belly button. As she walked, people's gazes lingered on her slender neckline with a hint of downy hair before passing by.
*Huff…*
Su-hui climbed onto the treadmill. She matched the speed and began running slowly. Her round buttocks began to sway gently. Her firm, toned buttocks swayed beautifully in rhythm with the running speed. Before long, someone behind her was openly staring at her.
“Member, you came early today?”
The trainer approached her, feigning familiarity.
*Ah… Haaah… Haaah Hello.*
“You came during the day. Today is…”
*Ah, yes. Haaah. It's the vacation.*
*Ah…*
The trainer scanned Su-hui's body from top to bottom with a hint of regret. Although the workout clothes hugged her tightly, her cleavage swayed lightly as she ran.
“If you finish running, I'll take a look at you.”
*Ah, yes.*
Su-hui ran for quite a while. Sweat poured from her entire body. The sports bra became slightly damp with sweat. Her smooth arms and shoulders glistened faintly with sweat.
*Huff…*
“This way, please.”
The trainer led Su-hui to the machine in front of the mirror. While waiting for the other members to clear out, the trainer took charge of the machine.
“Now, do you know the posture?”
*Yes, I know.*
Su-hui grabbed the handle on the machine. She pulled it down slightly, and the strap extended long.
“Push your hips a bit further back… Your legs should be shoulder-width apart…”
Su-hui spread her legs slightly and pushed her hips back. Gripping the handles with both hands, she pulled them downward.
*Yes… While giving stimulation to my breasts…*
The trainer's hand moved up to the area near Su-hui's tailbone.
“Push your hips back, tighten, one, two.”
On the trainer's hand, Su-hui's supple body felt… even through the leggings, the sensation of Su-hui's body that she had tasted several times made the trainer's lower body tense. Su-hui also felt her body grow warmer from the trainer's hand resting on her tailbone.
*Huuueh…*
The sound Su-hui made while exerting force was slightly lewd. The trainer glanced around cautiously. However, with so many other members around, he couldn't act too boldly. His hand slid down, brushing Su-hui's buttocks lightly.
*Huuung…*
Su-hui responded to the trainer's touch. Their eyes met in the mirror. There was a hint of regret in the gazes of both. If only they were alone at night, they would have already been naked, hanging on the machine, and thrusting their cocks inside. Su-hui felt her pussy growing wetter from that fantasy.
*Haaah… I want to do it again…*
Su-hui's wet pussy was visible between her pushed-back buttocks. However, today she was wearing proper underwear, so the leggings didn't get wet as quickly. After repeating the motion several times, the two moved on to the next machine.
“Bench press… Since it's been a while, let's do it lightly?”
At the trainer's words, Su-hui lay on the bench press. She positioned herself. The mound of her pussy peeked out between her slightly spread legs. The trainer's gaze pierced intensely between Su-hui's thighs. Pretending to help with posture, the trainer covered her view with his body. He seemed to grab her thighs, then pressed his thumb firmly against Su-hui's pussy.
*Hauep.*
Su-hui barely suppressed the moan that was about to escape. She glared at the trainer with resentful eyes. The trainer smiled craftily. He wanted to devour Su-hui's plump pussy with his fingers as if he were going mad. If he could, he would have rubbed her pussy until the leggings were soaked with moisture.
“Now, member, shall we begin?”
The trainer spoke as if nothing had happened. While Su-hui reached for the bar, he massaged her arms while pretending to help posture. The sweat and damp armpits of Su-hui's arms helped the trainer's lower body tense. The trainer's cock near him began to swell. Watching the trainer's cock inflate made Su-hui increasingly anxious. Even though she had masturbated twice before coming to the gym, with a man's cock right in front of her, she felt like she was about to lose her mind.
*Haaah… Trainer, can you rest for a moment?*
*Ah, yes.*
Su-hui sat up from the bench. After sweating enough, her cleavage visible between her sports bra glistened. The trainer's gaze couldn't leave her wet cleavage.
“Trainer.”
“…Yes?”
“I… would like to receive some personal training consultation…”
*Ah…*
Although personal PT was already registered, the trainer quickly replied to Su-hui's words guiding her to the consultation room.
“Then, shall we go to the consultation room for a moment?”
“…Yes.”
The trainer checked around. He and Su-hui entered the consultation room. A small glass window on the consultation room door was slightly covered with a sign that read “In consultation.” It was not a thick door, but soundproofing was not perfect. From outside, the sound of people's chatter and music could be heard faintly.
—thud
The trainer closed the door. He grabbed Su-hui's slender, wet waist with both hands.
“Ugh… Sorry…”
Su-hui twisted her body slightly. However, she didn't resist strongly.
“Members don't usually come at night…”
“I didn't think this would happen today…”
The trainer's hands stroked Su-hui's upper body. His hands, sweaty and smooth, slid softly. Soon the trainer had Su-hui pinned against the wall, lifting her arms upward. He pressed his face into her damp armpits and stuck out his tongue to lick.
*Haaueh… It's dirty… Because I sweated…*
“It’s fine.”
Su-hui's arms were pulled taut. Sweat that had soaked through her sports bra made her armpits damp. The trainer massaged the other armpit gently, like stroking it.
*Huuueh… A… Uuung…*
“You sweat nicely, member.”
“Liar… Uueh… Ang…”
“Shh… People outside can hear…”
*Huuuep…*
Su-hui bit her lip tightly. Otherwise, the sounds of people coming and going outside and the music could be heard clearly.
“Sounds… Uueh… I can't hold back…”
The trainer lifted Su-hui's sports bra upward. Her squeezed breasts were released and swayed. The trainer put his mouth on her white breasts, glistening with sweat and pink nipples, and sucked her small nipples to his heart's content without hesitation.
*Huuuep… Aaaah…*
Su-hui was pinned against the wall as the trainer sucked her breasts. Her arms were held by the trainer, stretching her upper body taut. The sounds outside, the sucking on her breasts, and her own soft moans were too stimulating.
*Aah… Aaaah…*
“Does it feel good?”
“…Yes… Uueh… Actually… I wanted to do it too much.”
The trainer rolled Su-hui's hardened nipples around with his tongue. His right hand slowly slid down and entered between Su-hui's leggings.
“You're wearing panties today?”
*Hic… There are a lot of people… Uh… Since it's daytime…*
“But why are you so wet?”
*Uung… Just now… Uh… I touched it…*
“Even with just that?”
The panties inside Su-hui's already sticky leggings were soaked with juices. If she hadn't come to the consultation room, the leggings would have been soaked with moisture soon. The trainer's fingers stroked the folds of Su-hui's pussy.
—squelch squelch
The fingers slid pleasantly between the folds. Su-hui's hairless pussy lips, plump and smooth, were spread open. The trainer, feeling the thin petals between the thick folds, slid his fingers lower, and the entrance of Su-hui's pussy, overflowing with juices, came into view.
*Haueh… Ang… Aaaah…*
“Shh… Quietly… Member…”
“But… Uh…”
The trainer's fingers were sucked into Su-hui's fully wet entrance. Since it was already wet enough, the fingers slid in smoothly.
*Haaueh!*
Su-hui stood leaning against the wall, exposing her breasts. She twisted her legs around the trainer's fingers.
Pussy Teasing
Su-hui's body trembled from the trainer's fingers.
