The Serendipitous Fitness Elastic Pants

Workout clothes come in many varieties, and according to Xia Lin's basic understanding, they mainly serve two purposes: "practical training" and "showing off."

Xia Lin had always held a disdainful attitude toward the latter because she had no one to show off to. She had already graduated from university without ever meeting a boy who made her heart flutter.

Su Bai was the first.

That's why she had impulsively bought this outfit, yet even now, just taking it out to look at made her blush with innocence, and she was still hesitating at the last moment.

A light blue tank top with a midriff-baring design, paired with extremely short compression shorts.

To be fair, this outfit was actually quite practical—hugging her figure perfectly, with the shorts providing some support for muscles and ligaments.

The real reason it felt so daring to Xia Lin was—

These workout shorts didn’t require anything underneath.

She could go commando!

It was a strangely bold selling point.

Xia Lin had secretly tried them on once in her dorm. And indeed, just as the seller advertised, even without anything underneath, they remained comfortable during movement—even lighter than a conventional outfit.

But with just a glance in the mirror, the faint outline was unmistakable.

So the other advertised feature, "anti-embarrassment," didn’t seem to work as intended.

She wasn’t sure if it was her problem or the designer’s.

Curious, she scrolled through the online store’s reviews and discovered something outrageous.

Many buyers actually praised this "subtly revealing" effect!

At first, Xia Lin was baffled, but after putting herself in their shoes, she quickly understood.

Those girls were probably wearing them privately for someone they liked—and who knew what kind of "workout" they were really doing with their boyfriends afterward.

As a gentle older sister, Xia Lin was good at empathizing, and she instantly got it.

So then…

Should she wear them for Su Bai?

Honestly, today Xia Lin did want something to happen with Su Bai. Lately, she had been feeling so pent-up that it even kept her awake at night, her mind filled with all sorts of wild thoughts. This couldn’t go on.

"Little brother, will you be my cure?"

Muttering to herself, Xia Lin bit her lip and made her final decision.

Her upbringing as a refined young lady made it impossible for her to pursue him outright, and since Su Bai was so composed, she had to resort to some seductive tactics.

So, a few minutes later…

"Little brother, what do you think? Do you like the vibe of this place?"

"It’s great, really great. No weird smells, and the equipment is better than most—almost like…"

Su Bai was mid-sentence when he casually set down the dumbbell and turned around, only to freeze at the sight of Xia Lin walking toward him.

The light blue midriff-baring tank top accentuated her slender yet curvaceous waist to perfection.

This wasn’t the kind of slimness achieved through dieting alone, but the result of years of discipline and training—a truly devilish figure.

The faint muscle definition, paired with her soft skin and the way it caught the light, was utterly mesmerizing.

But what really made Su Bai’s heart race was Xia Lin’s shorts… well…

"What are you staring at?"

"Big sis, you look amazing," Su Bai praised sincerely. "I don’t think there’s a more captivating personal trainer in the world than you."

"Oh, stop it. Personal trainer? How could I possibly train you? Look at those muscles—so solid, more natural than those bodybuilders, yet just as strong…"

Xia Lin pretended to chat casually about fitness, but inwardly, she was thrilled.

Tsk, tsk. Just as expected, Su Bai couldn’t take his eyes off that spot.

She took the opportunity to reach out and squeeze his muscles, stealing a little touch.

Even though they hadn’t started working out yet, both of them were already breathing a little faster.

"Big sis, you should warm up first. Later, whatever you’re training, I’ll spot you."

"Sure."

Xia Lin snapped out of her daze and shook her head helplessly. She was getting too eager—she should at least focus on the workout first and not let her mind wander in that direction.

Stretching, jogging… once her body was properly warmed up, she began her first exercise.

The bench press.

For most girls who frequent the gym, the most common workout isn’t the bench press.

It’s taking photos… just kidding, photos don’t count as exercise.

Treadmills and yoga mats are the usual destinations for the majority of gym-going girls.

Fewer girls do bench presses—it’s heavy strength training and comes with some risks.

For example, if two girls work out together without a personal trainer, their strength might not even be enough to safely spot each other during bench presses.

But with Su Bai here, Xia Lin felt completely at ease.

She loved bench presses. Proper training strengthened her shoulder and neck muscles, preventing issues from long hours of desk work or studying.

It also helped her maintain a more upright posture when standing or walking, giving her a more vibrant energy.

From Xia Lin’s observations, most young women these days had poor lifestyle habits, and their vitality faded rapidly after their twenties.

She couldn’t let that happen—she still had to compete with girls several years younger than her!

Chen Yusheng, the Wan sisters—they were all still green.

Meanwhile, Su Bai’s thoughts had already jumped to another level.

"No wonder Lin-jie’s chest is so perky—she does bench presses regularly."

"Why is your mind always in the gutter?!" Xia Lin laughed in exasperation. "Have you been staring at me this whole time?"

"Of course. Actually, the first time I saw Lin-jie on campus, I noticed right away—your figure is hands-down the best I’ve ever seen on any girl."

"Oh? And now? Still your number one?"

The moment she asked, Xia Lin realized something was off—ugh, that sounded way too jealous.

What was wrong with her? She was supposed to be the mature older sister, yet around Su Bai, she sometimes acted like a bashful little girl.

"Of course. Lin-jie will always be number one."

"But what about that girlfriend of yours? The one from the ‘Goddess Dorm,’ the Zhou girl? I’ve heard from classmates that her figure is insane too."

"Lin-jie, you’ve been asking around about me?"

"I didn’t ask! I just overheard it."

"Uh-huh. Sure, I believe you."

"…Enough nonsense. Come spot me—I’m starting."

Xia Lin lay back on the bench press, the high-quality leather providing a reassuring support.

Yet her mind was slightly restless. It suddenly occurred to her that when Su Bai stood at the head of the bench to spot her, he’d have a perfect view of the cleavage her tank top accentuated…

Just thinking about it made her shy again.

Xia Lin was, after all, a girl who embarrassed easily.
