A blush crept across Zhao Zhiran's face. She straddled the sofa, her rounded, white legs parted, revealing her plump, slightly swollen vulva, which slowly swallowed the erect penis once more.
Unlike her sister Tang Lanyan, Zhao Zhiran wasn't particularly fond of exercise, but her precise control made her workouts extremely efficient.
She could deeply train those deep muscle groups, so Zhao Zhiran's core strength was quite ample.
Furthermore, her skillful control allowed her to work muscles rarely touched in normal exercise, her calorie control was exquisite, always keeping her figure perfectly proportioned, neither gaining nor losing an inch, perfectly embodying the meaning of slender yet full, slim and well-proportioned.
Her lower abdomen was plump and rounded, and between her thighs was a rounded, full mons pubis,
covered in soft, sparse downy hair, forming a small, neat inverted triangle on the cleft of her vulva, its area narrow.
Like lush grass adorning a plump vulva, it made her inner thighs appear even whiter and more supple.
Her two plump labia were already wide open, pushed back by the penis, resembling a small, overeaten mouth.
Her pink flesh, faintly visible, clung to the shaft, delicate and tender like pink algae leaves. After panting for a while with her head tilted back, Zhao Ziran, relying solely on the strength of her waist, abdomen, and thighs, began to rise and fall gracefully.
Her beautifully shaped thighs slowly rose and fell, quickly making the long, curved penis glisten with moisture, as if coated with oil.
Soon, it was covered with a thin layer of sticky white fluid.
Her pair of full, firm breasts rose and fell, her sensitive body seemingly responding to the desire within, her pale areolas swelling and protruding slightly, pink and smooth.
A small, diamond-shaped opening appeared where the nipple had been hidden, revealing the delicate, pale cherry-colored bud, its beauty enhanced by the trembling.
"Mmm, ah~ ah~"
Luo Shaowen reached out and kneaded Zhao Zhiran's beautiful breasts. The touch was like the finest, softest silk soaked in smooth milk, filled with semi-solid, tender, and bouncy flesh, combining smoothness and suppleness.
The nipples were even more delicate, like cherries peeled but with only a thin membrane of moisture remaining—fresh and smooth, yet possessing a firmness different from the flesh, like an indescribably tender cherry pit rolling in the palm of his hand.
"Ah... ah ah!"
Zhao Zhiran's cry suddenly became rapid and sharp, her slender waist tightened, and her two round, long legs trembled, unable to support her weight, causing her to sink deeply into the ground.
The breasts in his hands were full and plump. His fingers, unable to fully grasp the edges, plunged deep into the smooth, snowy flesh. Each pinch brought him to the nipple, the silky, white flesh sliding between his fingers and palm.
The breasts trembled alluringly, deforming and being kneaded and rounded at will. Suddenly, when released, they bounced back to their full, rounded, plump shape, like little rabbits.
Their beauty almost surpassed imagination.
Luo Shaowen was also excited. Since their first night together, he hadn't really touched Zhao Zhirano.
Stimulated by the beautiful sight before him, his gaze deepened, and his large penis swelled even more, stretching and stimulating Zhao Zhirano's tight, moist vagina.
He thrust his hips forward, the impact making Zhao Ziran tremble. His large, burning hot penis pounded into her vagina, the soft, tender flesh of her flower instantly aching and sore.
"Ah...ah...ahhh...woo~"
Zhao Ziran's moans were tinged with sobs. Her slender waist straightened abruptly, highlighting the beautiful lines of her abdomen. A delicate sheen appeared on her ivory-like skin, glistening with fine beads of sweat.
Luo Shaowen's large penis thrust dozens of times, the sturdy sofa creaking and swaying precariously. The symphony of slapping buttocks, the sounds of thick fluids, grew louder and louder, like a minor melody.
As Zhao Ziran arched her snow-white neck, her swan-like neck trembling as if unable to bear the pressure, her small mouth opened wide, emitting a soft, mournful cry.
Her slender waist trembled uncontrollably, as if she were in a frozen wasteland, and a sudden surge of fluids welled up.
Luo Shaowen squinted, savoring the hot, wet, and slippery sensation of her honeyed orgasm, feeling the constant squeezing and kneading, as if a thousand invisible hands were pressing and massaging.
His large penis grew even harder, lifting Zhao Zhiran's still dripping, snow-white buttocks, suspending her delicate body in mid-air.
Between the two plump, peach-petal-like buttocks, his thick, long penis, as if just pulled from water, was slicked with a thin layer of white fluid, like a pillar drawing forth flower nectar.
"Smack!"
His large penis suddenly thrust upwards, causing her beautiful flesh to tremble, and white fluid to splatter everywhere.
One thrust after another, fast and deep, intense thrusts, stepping on the tail end of Zhao Zhiran's orgasm, pushed her to a new climax of desire.
Her labia majora, swollen and parted, were moist and red, resembling two plump, swollen orchid petals.
The two engorged labia minora inside curled and rolled, turning a deep, vibrant crimson. White fluid coated the penis, and with each thrust, it pushed the thick, white, viscous fluid onto the shaft, soaking Luo Shaowen's pubic hair and the sofa beneath him.
But each time it withdrew, it brought out another thick, sticky fluid.
The lewd sounds echoed in the room, while on the other side, several researchers in protective suits restrained Tang Lanyan back onto the table.
Only a continuous release of high-concentration anesthetic gas could temporarily render Tang Lanyan unconscious.
An ordinary person exposed to such an environment would have their nervous system completely anesthetized within seconds, almost never to wake up again.
But for Tang Lanyan, the time she remained unconscious was dwindling. While an elephant couldn't last even a minute, Tang Lanyan could continue to be submerged beneath it, regaining consciousness within minutes once the release stopped.
For ordinary researchers, it was essentially no different from dealing with dangerous tigers, leopards, or elephants.
By the time they finished, the other side was nearing completion.
