The Tuan Tuan Agreement

Bai Jingjing paused, a flicker of surprise in her eyes.

She had originally intended to wear pajamas, but Xia Chu had specifically instructed her to wear only her underwear.

‘Did that mean pajamas were forbidden?’

Although a faint unease stirred within her, she agreed, as it was a request from her employer, the esteemed ‘big sister.’

Conveniently, Luo Xuan had helped her buy several sets of underwear yesterday, so she had options.

****

Xia Chu’s bedroom, in contrast to Luo Xuan’s, was notably simpler and brighter, entirely lacking the plush teddy bears that adorned Luo Xuan’s.

However, her nightstand was adorned with several anime girl figurines.

Among them were Kagura Nana, Pecorine, Saren…

Xia Chu lay supine on the bed, her hands cupping her ‘tuan tuan’ (TL Note: A playful term for breasts), her heart thrumming with a delicate nervousness.

She wished to press down on her rapidly beating heart, but her generous ‘tuan tuan’ stood in the way, forcing her to press in this peculiar manner.

Having lived alone for such a long time, usually feeling awkward even sharing a house with others, she had, tonight, actively invited another girl to share her bed.

Even among medical treatments for social anxiety, this could undeniably be categorized as shock therapy.

Still, since Bai Jingjing was her girlfriend, sharing a bed seemed perfectly reasonable, didn’t it?

Just as Xia Chu entertained this thought, she looked up to find the young girl standing, exquisitely poised, at the doorway.

“How are you dressed…”

‘So alluring!’

Bai Jingjing blinked her innocent eyes, remarking with an air of pure innocence: “Sister Xia told me to come in wearing underwear.”

While the pink and white color scheme suited her perfectly, the style of the underwear verged on the audacious for a purportedly girlish aesthetic.

A mere strip of fabric, barely a third the size of her ‘tuan tuan,’ spanned across them.

The fabled ‘equatorial’ style underwear.

Several delicate, light-colored strings connected the fabric, fastened around her smooth back and alabaster neck.

The panties were a similarly minimalist arrangement of fabric and ties, and even with two small bows fastened on either side of her thighs, they failed to imbue it with even a hint of additional innocence.

It was quite cute, yet it possessed a distinctly alluring charm.

“I asked you to wear underwear, not to wear, to wear,” Xia Chu stuttered, her gaze flitting wildly, “to wear *this* kind of underwear.”

‘I know I told you to come in wearing underwear, and you did, but is this really what you should wear?’

‘Wearing this type of underwear like this, are you truly doing justice to the advantages of your figure?’

‘Oh, you *are* doing it justice, but you’re overdoing it to an alarming degree!’

“Is there a problem with this one?” Bai Jingjing blinked with a bewildered expression. “There shouldn’t be, right? Sister Luo helped me buy it.”

‘If she had bought it herself, there might be an issue, as it was her first time being a girl, so she wasn’t familiar.’

‘But Luo Xuan was a veteran beauty; the underwear she helped buy surely couldn’t possibly be problematic?’

“What? Luo Xuan bought this for you?”

Xia Chu suddenly understood, cursing inwardly at having been outmaneuvered by her best friend.

‘Luo Xuan just wanted her to be alluring!’

Bai Jingjing had been standing there for a while, and a soft shiver coursed through her frame.

She was only in her underwear, and the air conditioning was on in the bedroom.

“You, you come in first,” Xia Chu gritted her teeth, pulling back the duvet. “But no fidgeting.”

“Okay.”

Despite these words, even with Bai Jingjing being perfectly well-behaved, two people sharing a single blanket inevitably led to the softest of brushes, regardless of whether they ‘fidgeted.’

‘Her skin is truly exquisite.’

The thought instinctively flickered through Xia Chu’s mind.

‘Soft, smooth, and fragrant.’

Indeed, Bai Jingjing found herself entertaining similar thoughts.

Moreover, due to their generous endowments, when compared to other girls, their shared blanket led not just to touches, but to more significant, delightful collisions.

Xia Chu’s face flushed a deeper crimson; this was truly becoming shock therapy.

“You, you sleep properly, let me make this clear,” she declared, each word carefully enunciated. “You sleep your way, I’ll sleep mine. No overstepping.”

This was an agreement between two ‘big tuan tuan’ girls, concisely termed the ‘Tuan Tuan Agreement.’

“Okay,” Bai Jingjing closed her eyes. “Good night.”

With the lights off, the bedroom grew quiet, and the girl beside her, true to her name, was docile and still, her breathing a barely perceptible whisper.

The room seemed no different from usual, save for, well… a subtle, inviting aroma of coconut milk.

The sweet, comforting aroma lulled Xia Chu into a peaceful slumber as well.

Halfway through the night, she stirred, half-awake and hazy, feeling a slight stuffiness in her chest and a soft, delicate form pressed intimately against hers.

It turned out that, even in their sleep, the two girls had, without realizing it, gravitated into an embrace.

Perhaps it was due to their ample curves; according to the law of universal gravitation, they had simply nestled into each other in their sleep.

A slight constriction settled in her chest because, with their ‘tuan tuan’ being similarly positioned, embracing meant their soft forms pressed intimately together.

‘Now they were ‘tuan tuan yuan yuan’ (TL Note: A playful phrase combining ‘tuan tuan’ (breasts) with ‘yuan yuan’ (round/complete), implying a snug, harmonious fit).’

Half-asleep, Xia Chu found the sensation incredibly comforting, so she merely shifted back a fraction, then peacefully drifted back to sleep.

Zzzz

Sunday morning crept in unnoticed while she was still deep in slumber.

It was the first time she had gone to sleep without using her phone, yet Xia Chu had slept a full ten and a half hours, only stirring past nine in the morning.

Primarily, the sleep had been so exquisitely sweet, leaving her entire body suffused with a profound comfort.

“Mmm…”

Xia Chu stretched a pair of pale arms from beneath the duvet, indulging in a luxuriant stretch.

It had been a long time since she had such a good night’s sleep, perhaps, truly, never before.

The girl beside her was long gone, leaving behind only a faint, lingering warmth, though soft sounds emanated from the kitchen, suggesting the preparation of breakfast.

Xia Chu lay back down, pondering the extraordinary depth of her sleep the previous night.

Aside from the inherently delightful coconut milk scent, the primary reason lay in the exceptional ‘girl pillow.’

She recalled that, seemingly, as they slept, they had naturally embraced, which had been wonderfully soft and yielding.

The way their ‘tuan tuan’ had pressed together was particularly comforting.

Bai Jingjing’s ‘tuan tuan’ was comfortable, and Xia Chu’s ‘tuan tuan’ was equally so.

‘Don’t even ask; if you do, the answer is simply double the pleasure.’

Xia Chu couldn’t help but recall what her best friend Luo Xuan had told her on QQ last night, fervently urging her to try it—claiming that even without any ‘seductive’ intent, the simple act of cuddling and closeness was wonderfully beneficial.

Indeed, it had been quite delightful.

However, as Xia Chu slowly returned to full consciousness and prepared to dress, she suddenly noticed a problem.

Perhaps their nocturnal embrace had been too fervent, leading to a minor incident, the undeniable consequence of which was—

She required a fresh pair of panties.

*Thump-thump-thump, thump-thump-thump.*

Her ample ‘tuan tuan’ remained utterly unperturbed, yet the small heart beneath them pounded like a startled rabbit, feeling as though it might burst from her chest.

‘They had slept so close; had Bai Jingjing noticed anything when she had risen?’

Xia Chu was several years older than Bai Jingjing, and her appearance projected the image of a cool, sophisticated older sister, but now…

‘What was she to do!’

Before she could devise a solution, the girl’s soft voice drifted in from beyond the door: “Sister Xia, are you awake? Breakfast is ready.”

“I-I’m coming right away!”

There was simply no other recourse; she had to swiftly change into a fresh pair, discreetly tuck the soiled panties beneath the duvet, then get dressed and make her way to the living room for breakfast.

‘For now, they must remain hidden. Once Bai Jingjing departs for groceries, I will swiftly retrieve and scrub them clean,’ the ‘big sister’ Xia Chu meticulously strategized for herself.
