Naked Sex in the Pool
I started out just as Yeji instructed, gripping a kickboard and practicing how to float.
Since it was my first time swimming, everything felt awkward at the start. My whole body tensed up, and I kept wanting to sink.
“Sihyuk, loosen up. Think of it as surrendering your body to the water.”
Yeji skillfully adjusted my posture. Every time her firm yet soft hands gripped my back and shoulders, a strange feeling stirred through me. Even underwater, everything felt far more sensitive than usual.
“Yes, just like that. You’re doing great.”
Yeji was an excellent swimming teacher. She taught this complete beginner how to float, how to apply just the right amount of tension, how to kick the water, and even the most efficient form. She zeroed in on the essentials and guided me so that I could actually enjoy it. Thanks to her, I gradually started having fun.
The sensation of my body becoming one with the water, slowly but steadily moving forward, was fresh and new.
“You’ve got good athletic sense. You’re picking this up way faster than I expected. Is it because you’ve got so much muscle?”
Her praise made my shoulders lift with pride. Before I knew it I was completely absorbed in swimming. I thrashed through the water without even having the leisure to notice Yeji’s sexy body in her bikini right beside me, helping me the whole time.
Just like that, a full hour flew by.
“Let’s take a short break. If you overdo it, your muscles will seize up.”
At her words I pulled off my swim cap and goggles. The cold water touching my eyes and head felt wonderfully refreshing. That was when it happened.
—Splash!
“Huh?”
Yeji splashed water at me with a face full of mischief. I wiped the sudden spray from my face only to find her already darting away, laughing with a bright little giggle.
“Heh, this is how you’re supposed to play during break time!”
“Oh, so that’s how it is…”
I laughed too and launched my counterattack. Scooping water with both hands, I hurled a powerful splash straight at her.
—Whoosh!
The water column powered by my strength was on a completely different level from what she had thrown. She let out a cute scream and nimbly dove underwater to escape.
And so the first water fight of my life began.
At first Yeji had the upper hand. She knew how to splash efficiently and moved far more freely in the water. But I didn’t know any technique, so I just pushed with raw power.
—Bam! Bam! Whoosh!
I unleashed massive streams of water at her one after another like I was firing artillery shells. Yeji laughed and swam underwater to dodge my attacks, but the space she could move in kept shrinking.
“Stop right there!”
I finally cornered her against the pool wall. With nowhere left to run, Yeji’s face was filled with pure delight. I didn’t miss the opening and lunged at her.
“Got you!”
I pinned her between the wall and my body, playfully sprinkling water on her face. Yeji gasped for breath between bursts of laughter.
“I surrender, I surrender! You win!”
“You have to take a punishment.”
“What kind of punishment?”
“Hmm…”
We stayed like that for a long while, laughing as we looked at each other. The noisy splashing died away, leaving only our ragged breathing and the soft lapping of water echoing through the pool.
The laughter faded from Yeji’s face. Beneath her wet lashes, her brown eyes glistened moistly. Hot breaths slipped from her slightly parted lips and brushed against me.
The mood shifted in an instant. Through the clear water, the sexy curves her bikini barely covered were laid bare—the dizzying valley of her cleavage, her slim waist, even the faint outline of her pubic hair swaying with the ripples.
I couldn’t hold back any longer and crushed my lips against Yeji’s.
—Mmnh!
“Nngh…!”
Yeji seemed startled for a second, then immediately welcomed my kiss with joy. Kissing in a swimming pool was a first for both of us. Our body heat mixed with the coolness of the water, creating a strange, intoxicating sensation.
Normally the height difference would have forced me to lean down, but here in the water I wrapped both arms around her firm waist and lifted her lightly. Thanks to the buoyancy she floated up as if she weighed nothing at all.
Our eyes met at the same level. Gazing steadily into hers, I kissed her even deeper, more thoroughly. Yeji, just as worked up as I was, tangled her tongue with mine eagerly.
I don’t know how much time passed. When our lips finally parted, Yeji panted and whispered,
“Chuu… hah… We’re probably the first people to ever kiss here.”
I grinned and answered,
“We’re probably the first to have sex here too.”
My bold words made Yeji’s face flush slightly. She pressed herself even closer and breathed hotly into my ear.
“I… my pussy is soaking wet right now.”
That single sentence made my cock surge to full hardness. Without a moment’s hesitation I stripped off my swim trunks and tossed them aside. Yeji, as if she’d been waiting, untied the strings of her bikini bottoms.
A suddenly arousing idea hit me, so I snatched the bottoms from her hand and flung them toward the center of the pool.
“Hey!”
Yeji laughed in disbelief, then grabbed my trunks and threw them just as far.
I leaned my back against the pool wall first. Movement was unstable underwater, so I needed solid support. Yeji came to me without hesitation. The sight of her smooth lower body gliding through the water’s resistance was pure sensuality.
She wrapped her legs around my waist and pressed the entrance of her pussy against my cock. When that hot, soft flesh rubbed against my glans, a shiver ran through my entire body.
Yeji gripped my shoulders and slowly lowered her hips.
—Splash.
Instead of the usual sound of penetration, only the clear lapping of water could be heard. Right after, Yeji’s sweet moan echoed through the pool.
“Ahn… it’s… going in…”
The pleasure must have been intense; she bit her lip hard and looked up at me. Those wet eyes were ridiculously sexy. Even underwater her pussy didn’t feel much different from usual. All that Kegel training she’d been doing paid off—her vaginal walls squeezed me with far more springy elasticity than last time.
Underwater sex was a first, so moving felt a little awkward. It was hard for the man to thrust, which meant Yeji had to take the lead completely. Realizing that herself, she gripped my shoulders firmly and began rocking her hips on her own.
—Slap, slap.
“Haah, hnn…!”
Up and down, forward and back. Her movements were clumsy but passionate. True to her track-and-field background, her stamina and strength were exceptional. I showered her with kisses while groping her wet body.
Yeji’s pace gradually picked up. I had expected her juices to wash away in the water and leave her pussy dry, but that barely happened. Hot love juices kept welling up from inside her in proportion to her pleasure.
“Haa, haa, aahng…! Hnnngh…!”
She thrashed her hips wildly, then suddenly shuddered and reached her first climax. Her pussy clenched and milked my cock in rhythmic pulses. I helped the piston motion by firmly kneading her soft ass.
Even after coming once, Yeji didn’t stop. If anything she grew bolder.
“Sihyuk, it feels so good…! Your cock… I love it so much!”
She didn’t hold back her moans, openly crying out her pleasure. We kept fucking for a long while, and Yeji came again and again.
Maybe it was the tension of being underwater, or maybe Yeji’s body was just especially hot, but the urge to cum built faster than usual for me as well.
—Spurt, spurt, spurt!
I poured hot semen deep into Yeji’s pussy. As always, it was an extremely satisfying orgasm. Watching the milky white fluid disperse into the water brought a slight twinge of guilt. I felt a little sorry for whoever had reserved the pool for the afternoon.
The instant I finished cumming, Yeji dunked her head underwater. Holding her breath, she latched onto my cock and began a cleaning fellatio.
She’s going to run out of air…
I marveled at her dedication while savoring the sensation of her tongue thoroughly licking my glans clean.
Once the cleaning fellatio was finished, Yeji stripped off the last remaining piece—her bikini top—and tossed it away. Completely naked, she locked eyes with me for a moment, then swam through the water as elegantly as a mermaid who had finally found her element. Watching her, I went blank.
A woman swimming naked. It was the first time I’d ever seen it, and it was dizzyingly beautiful. Entranced, I followed her, cutting slowly through the water with the strokes I’d just learned.
In the middle of the pool we collected the swimsuits Yeji had thrown earlier. She headed for the shallow end so it would be easier to get dressed. Handing me my trunks, she said shyly,
“Thank you… for asking me to teach you how to swim today.”
Maybe it was because I’d just watched her swim naked, but I couldn’t answer as lightly as I normally would.
“Thanks for showing me something amazing.”
Yeji laughed, asking what I meant by that. Just as she was about to put her bikini back on, I grabbed her hand a little urgently.
“Until swimming is over… don’t put it on.”
Her eyes sparkled with mischief.
“Really?”
She obediently let go of the bikini. Then she leaned her back lightly against me, fully aware of what I wanted. Unable to hold back, I wrapped my arms around her naked body. And without a second’s hesitation, I sank my cock into her wet pussy once more from behind.
“Haaahng…! I love it when you thrust from behind, hnnn…!”

It looked like I wasn’t going to be leaving this pool anytime soon today.
