You're Really Pretty Right Now
An Seo-ra had an extremely strong libido, though she hadn't realized it herself. There was only one reason she'd never noticed until now.
She'd been so busy she couldn't even think about guys. She'd been releasing her sexual urges through high-intensity workouts that left her too exhausted to move.
'A boyfriend is just a hassle.'
Of course, she was in the bloom of her twenties, so it wasn't that she had zero interest in dating. When she saw her friends dating one or two guys and flaunting their affection, she sometimes considered accepting one of the guys who confessed to her. To be blunt, she was also curious about what sex would be like.
But no matter how she thought about it, the downsides of having a boyfriend far outweighed the benefits. She was already leading a busy daily life and had no time to devote to a relationship. More than anything, dating someone she didn't even like just because she was curious about romance or sex would be a shitty thing to do to the other person.
So she'd tried to convince herself that a boyfriend was just a hassle, and not having sex was perfectly fine.
'I fucking love sex!'
Jjyubop jjyubop jjyubop jjyubop!
Every time she bounced her hips, a tingling sensation rose from deep in her belly. It felt like the sexual desire that had been smoldering inside her was finally erupting. When his cock stirred inside her and touched a sensitive spot, moans burst out of their own accord, completely beyond her control.
"Ha-euht! Ha-ahng!"
Such embarrassing noises coming from her own mouth. She didn't even let out sloppy groans like this when she was straining to beat a lifting record.
"Ha-aht. The time we did it really was... hik!"
Quite some time had passed since she'd had sex with Kang Cheol-jin. Whether the intense sensations from that night had been real or a dream had grown increasingly hazy.
The feeling that it had been incredibly good lingered, but she sometimes questioned whether it had really been that good.
But today, she was certain.
A boyfriend, maybe not—but sex was a necessity. It was well worth carving time out of her busy schedule for.
Releasing sexual urges through exercise?
Maybe it was possible in the moment. But over time, her superior stamina only amplified her libido. If she'd never experienced sex, maybe exercise would have been enough—but now that she had, it could never fully replace the real thing.
"W-wait. I'm coming right now, nuna— uheok!"
"Heu-uhk! J-just a little more!"
An Seo-ra looked at Kang Cheol-jin's flustered face and moved her hips even harder. A ticklish sensation was spreading inside her belly. She wanted to feel that orgasm she'd experienced before, just one more time.
"Hueok!"
Kang Cheol-jin's groin jerked upward. Watching him moan and tremble gave her a strange sense of pleasure.
At that moment, the something that had been building up inside An Seo-ra burst.
"Ah, ah, a-hak! Heu-uuht! Eu-heuk...!"
The electric feeling that started in her lower belly shot up along her spine. Her vision went white and she collapsed onto Kang Cheol-jin's body, trembling all over.
'So fucking good...!'
It was almost unfair that she'd lived her whole life not knowing this feeling. She thought she finally understood why her friends cycled through boyfriends so fast or went to clubs for one-night stands.
"Haa, haa...."
An Seo-ra lifted her head, panting. Then she saw Kang Cheol-jin groaning like a soul-drained zombie: euu-euh.
"...Pfft."
She let out a soft laugh.
'This feels kind of satisfying. Makes me feel like I won, somehow.'
When they'd done it before, she'd been completely helpless against Kang Cheol-jin. His face had stayed composed the whole time, and even though that smug look annoyed her, it was her first time so she'd just been swept along by his movements.
But now the tables were turned, and Kang Cheol-jin was the one rendered helpless. Seeing him this wrecked because of her brought an immense sense of satisfaction.
'Heh-heung. That time it was just because it was my first time. Who am I? I'm confident my stamina's better than most guys'.'
It was well-founded confidence. She'd been doing weight training, running, and boxing for years. Pure strength aside, women could produce better endurance performance than men.
'Honestly, my pride was a little hurt last time....'
And yet the situation had changed after just two times. Just look at this spaced-out face. She smirked and pinched Kang Cheol-jin's cheek as if he were cute.
"Was it that good? To the point you can't come to your senses? Cheol-jin's a pushover, huh?"
"......?"
"Sheesh, how cute. No need to take it personally. You know how much I work out."
An Seo-ra chattered away, reveling in the joy of victory. Then she took out one more condom and said,
"You're not already worn out, are you? We did cheating too, so put some more effort in. Nuna will get you ha—"
Bulkkeun-bulkkeun.
"...Huh? What's this, why is it up?"
An Seo-ra, who'd been about to change the condom, widened her eyes. Despite having just come moments ago, his cock was rock-hard and erect. It hadn't subsided and then gotten hard again—the erection simply hadn't gone down to begin with.
Kang Cheol-jin spoke with a sulky expression.
"What do you mean, why? Nuna didn't stop and just kept going."
"...It stays up if you don't stop?"
"I don't know either. Supposedly there's a refractory period or whatever, but I've never really felt one. Gimme the condom."
"Uh, uh-huh."
Kang Cheol-jin pulled off the used condom and put on a new one.
An Seo-ra looked at the used condom and stuck out her tongue in amazement.
"Holy shit. This is only the second time—why's it so much?"
"What's new about that? We did it last time too, didn't we?"
"No, I was out of it then... Do you always come this much?"
An Seo-ra made an appalled face. That much semen had gone inside her? No wonder it kept trickling out even after she'd taken a long time getting it out.
"Probably. Well, some of it might be extra because nuna squeezed it out of me."
"Squeezed it out of you. Yah."
"...I told you to stop for a sec but you didn't. Even though I said I was coming. That's squeezing, right?"
Was it just her imagination, or did his tone sound a little sharp?
An Seo-ra flinched and tried to gauge his mood, a sudden unease washing over her.
"...You're not mad, are you? I was right about to go too, that's why."
"Nope. Why would I get mad over something like this? I'm not that petty a guy."
"R-right?"
Then why did he look mad?
An Seo-ra instinctively sensed something was off.
Just then, Kang Cheol-jin smiled brightly and said,
"Instead, I'm going to do the same thing."
"D-do what?"
"Just, you know—I won't stop until I come."
The condom change was complete.
Kang Cheol-jin twitched his rigidly erect cock and approached An Seo-ra.
"Even if nuna cries and begs me to stop."
"...Uh, Cheol-jin-ah?"
Flinch.
"Spread your legs for me."
"Nu-nuna's sorry, okay? Yah. Yah. Wait a sec. Hueok?!"
Jjeureureureureut!
His cock plunged all the way to the root in a single thrust.
An Seo-ra's mouth fell open—huk. The sensation was completely different from when she'd inserted it herself and moved.
"We did it once already, so we don't need foreplay, right?"
"N-no. I think we might need... it...!"
"No. We don't."
"Then why'd you ask... heo-eok!?"
Jjugeok jjugeok jjugeok jjugeok!
The intense thrusting began.
Kang Cheol-jin caressed her defined abs as he drove his hips hard. Cheolsseok—flesh smacked against flesh. Her body, honed by exercise, had a uniquely firm springiness.
"Heu-euk! Ah, ah! Too hard! A little slower...!"
Due to anatomical structure, men and women inevitably had different ways of exerting force. In sex, most positions favored the man's ability to apply force. It was only natural, since men were the ones with the tool—the club—to begin with.
An Seo-ra gasped for breath at an intensity that couldn't even be compared to when she'd moved on her own. Before she knew it, both of her hands were caught by Kang Cheol-jin. It looked like tenderly interlocked fingers at first glance.
But in reality, those interlocked fingers were like handcuffs. No matter how many years she'd trained, she couldn't match Kang Cheol-jin's strength. Despite his relatively short training history, his natural strength was excessively powerful.
Cheolsseok cheolsseok cheolsseok cheolsseok!
Kang Cheol-jin kept up the piston motion without pause, just as she'd done to him earlier. He didn't control the tempo at all—just slammed his flesh against hers.
Of course, sex didn't necessarily feel better just because it was harder and faster. Especially for someone as hung as Kang Cheol-jin, the pain could outweigh the pleasure.
But An Seo-ra, conditioned by years of exercise, was accustomed to a certain degree of pain, and her trained muscles were sturdy enough to absorb the impact and endure the rough treatment.
Besides, they'd already finished one bout of intense sex.
She was fully warmed up, her body primed and ready. The rough thrusting registered as pleasure first, before pain.
"Heu-eu-eu-euk! A-hik!"
Pleasure you can't control is inherently more stimulating—by the same principle that being tickled by someone else is more sensitive than tickling yourself.
"Eu-heo-eok! Heut, heu-o-ok-!"
There were no pretty, pleasant-sounding moans. Bestial cries erupted from An Seo-ra's mouth.
"Ah, it's so fucking good. Nuna's pussy is clamping down like crazy. Seems like the deeper I put it in, the more it does that."
Moments later, the tip of his cock reached all the way inside and rubbed against her cervix.
"......?!"
An Seo-ra opened her mouth wide. No moan came out. At the immense pressure, far beyond anything she'd imagined, all she could do was gasp for air—heuk.
Kku-uk. Kkuk. Kkuu-uk-!
At the sensation of being persistently pressed deep inside, An Seo-ra remembered something she'd completely forgotten. The feeling from that time she'd been utterly helpless against Kang Cheol-jin finally came flooding back.
'Th-then too, it was like this, ah... I'm coming....'
A sensation welled up that was similar to when she'd bounced her hips earlier, yet different. It was the moment she realized that even orgasms had degrees. Her vision went white.
Deol-deol-deol-deol.
An Seo-ra's body trembled violently. Her hips bucked and spasmed involuntarily, snapping forward and back.
Uleok— kkul-reok kkul-reok. Byureureureurut.
Even as Kang Cheol-jin came, he kept the tip pressed inside. Big movements were difficult, but simply pressing down wasn't hard even mid-ejaculation.
"Seo-ra nuna, you're really pretty right now."
He smiled with satisfaction as he looked at An Seo-ra, whose eyes had rolled back, showing white.
