Zhang Xiaoman was a perfectionist, and no matter how her body responded to Zhang Yang, she was unwilling to cross certain lines.
Only on their wedding night would she fully give herself to Zhang Yang.
"I'm sorry, I was impulsive."
Zhang Yang apologized; he truly loved Zhang Xiaoman and did not want to disappoint her.
Seeing Zhang Yang still panting heavily, struggling uncomfortably, Zhang Xiaoman gritted her teeth.
"I... I can use my mouth, but this is not to become a habit."
Zhang Yang's spirits lifted, this was an unexpected delight.
Zhang Xiaoman glared at Zhang Yang, "Then stay still, don't move, or you'll take care of it yourself."
She then complained, "Who asked you to have such a 'Big Baby'? I can only do my best."
"Mmhmm!"
Zhang Yang was already very satisfied.
Meanwhile, neither of them noticed at the doorway, a pair of beautiful eyes unblinkingly watched this heated scene.
Xia Xue's mouth slightly open, watching Zhang Xiaoman stretch out her tongue, she unconsciously did the same.
One hand subconsciously wandered into her panties.
Realizing what she was doing, Xia Xue quickly stepped back.
Her face flushed with embarrassment, she scolded herself silently, "What am I doing? How can I spy on my own sister and brother-in-law?"
Yet in a blink, she couldn't help but sneak another look.
"Just... just this one time."
This feeling of shame and thrill filled Xia Xue's heart and through that hand, reached her most sensitive spot.
The frequency of her hand movements unconsciously matched the movements of Zhang Xiaoman's head and hands.
The sensation felt as if she herself were riding on that massive object, moving up and down.
Half an hour later, she had climaxed twice just using her hand.
In the past, she would have stopped after one climax, but now she was waiting for the man inside to finish.
Finally, as the third climax was about to arrive, a voice came from inside.
"Oh, why didn't you say something?"
Then she saw Zhang Xiaoman hurriedly taking a tissue and spitting it out.
Outside, Xia Xue also sat weakly on the ground.
Her panties were already soaked through.
But without time to think further, even with her legs feeling weak she hurried back to her own room.
Having had a rare release, Zhang Yang slept comfortably through the night.
The next day, Zhang Yang cleaned the rooms as usual.
But this time, he didn't see any damp panties in the bathroom; it seemed his sister also had times when she was tired.
Zhang Yang also breathed a sigh of relief, at least today wouldn't be so agonizing.
However, what puzzled Zhang Yang was that, in the afternoon, Xia Xue came out of her room looking quite pale.
She didn't drink her usual black coffee and didn't do any yoga either.
She came out wearing just a nightgown.
"Sis, what's wrong? Are you feeling unwell?"
Xia Xue didn't respond but instead gave Zhang Yang a somewhat resentful look.
That look, it was similar to Xiao Man's last night, but Xiao Man was aggrieved from being upset by him, he hadn't provoked Xia Xue though.
"Sis, if there's anything I haven't done well, just tell me, I'll definitely change."
After hearing this, Xia Xue felt helpless. What could she say?
She certainly couldn't confess that she had spied on the young couple last night and climaxed three times, causing her to have cramps in her stomach and legs, resulting in a sleepless night and even now, she daren't make any abrupt movements.
That was too embarrassing.
"I'm fine, it's just that I might have stretched this area too much yesterday during dance practice."
Upon hearing this, Zhang Yang immediately showed concern, "Oh, that's alright, it's not a big issue. I'll give you a massage and it should be fine."
"Ah?" Xia Xue was somewhat surprised.
"Hehe, has sister forgotten what I do for a living? Although I haven't officially started working at the hospital, at our school, my skills are ranked highly. Plus, my family has been practicing Chinese medicine for generations. Massage is just a piece of cake for me."
Xia Xue was still a bit embarrassed, but her lower abdomen really hurt too much.
In the end, she reluctantly nodded, "Alright then, just massaging my legs will be fine."
The position of the lower abdomen was too awkward, and Xia Xue ultimately felt too embarrassed.
Zhang Yang did not suspect anything.
But as he watched Xia Xue quietly lying in front of him, like a piece of art for him to appreciate, he remembered the scene in the restroom the day before, and suddenly felt his mouth dry and his tongue parched.
These legs, every time Xia Xue practiced yoga, he had successfully played with them.
He hadn't expected that today he would actually get his wish.
Feeling Zhang Yang's scorching gaze, Xia Xue's body tensed up, and her heart was not at peace either.
After muttering "Amitabha Buddha" to himself, Zhang Yang finally started.
The fine skin and smooth touch greatly satisfied Zhang Yang.
Gradually, his hands moved from the lower legs to the thighs, and Xia Xue occasionally let out a comfortable, soft "mm" sound.
But as Zhang Yang's hands reached near the upper thighs, Xia Xue suddenly clenched her legs tightly.
Because she had started to feel a warm flow inside her body.
But unknown to her, this movement suddenly triggered a cramp in her lower abdomen.
Xia Xue covered her lower abdomen with both hands, her pretty face turning pale, and suddenly she experienced a cramp.
"It hurts, so much!"
Zhang Yang immediately diagnosed Xia Xue's condition, "Sister, don't move, let me do it."
At this point, Xia Xue wasn't thinking about shyness anymore, letting Zhang Yang move her hands, and her skirt was also lifted up.
The scalding hands, and that unique intensity, after coming through, relaxed Xia Xue's furrowed brows, and it truly stopped hurting.
But then she suddenly realized that she was only wearing a thin pair of panties, completely exposed in front of Zhang Yang.
Xia Xue hurriedly covered herself with her hands, "Zhang Yang, it's okay now, I'm not in pain anymore."
But Zhang Yang said, "Sister, do you have severe menstrual pains usually? Otherwise, the lower abdomen wouldn't cramp so easily. My massage technique can improve your menstrual pain, let me try it."
Zhang Yang knew it wasn't entirely appropriate to say this, but he really didn't want to stop now.
Of course, he said it was just to "try it."
"Um..." Xia Xue was still hesitant, but Zhang Yang really hit the mark.
"Can you truly mitigate my menstrual pain?"
"Yes, I can, sister, you don't have to be shy, I am a doctor."
"Alright then, but don't tell Xiao Man, after all, this is somewhat..."
Hearing Xia Xue's agreement, Zhang Yang naturally concurred.
"Sister, then I'll start now. Relax a little, don't be nervous, and don't resist your body's reaction, otherwise it will affect the treatment effect."
Zhang Yang spoke sincerely.
Seeing Xia Xue nodding with her eyes closed, Zhang Yang smiled slightly.
He then warmed up his hands and continued to massage Xia Xue's lower abdomen. Gradually, he pulled down her underwear slightly, barely revealing the top of that slit.
Xia Xue also bit her lower lip, occasionally letting out enticing moans.
This sensation of both comfort and thrill kept her from speaking out to stop it, even though she could feel those hands moving steadily closer to her most private area.
At the same time, Zhang Yang had noticed that the area beneath the underwear was already wet.
He didn't expect Xia Xue to be this sensitive, even more so than Xiao Man.
At that moment, an impulsive thought surged in his mind, wanting to explore that forbidden area to see just how inundated it really was.
