Chapter 8: Demonstrating Expansion and Contraction Abilities (Part 1) 

Liu Yong's chin was lifted by the man's shoe tip, directing him to look forward. Number Sixteen immediately changed his posture upon hearing the man's words. He spread his kneeling knees apart, his testicles the size of a child's fist and his penis as thick as a water pipe and as long as a forearm hung heavily between his legs. The duck egg-sized glans gently brushed the ground as his penis swayed. 

Number Sixteen then lowered his upper body, supporting himself only with his shoulders and forehead. His hands grabbed his thick, full buttocks and spread them apart forcefully, completely exposing the hidden anus. 

Although Liu Yong had never been with a man before being brought here, he knew a bit about these things. Out of curiosity, he had even watched some gay porn, where most of the men being penetrated had loose anuses that seemed to prolapse during intercourse. 

However, Number Sixteen's anus, though clearly well-trained, had only a slight circular protrusion at the opening. It was tightly contracted to the size of a pinpoint, looking as if even a finger couldn't penetrate it. 

The color of the anus was somewhat dark, but it was unclear if this was natural or the result of training. 

Liu Yong watched as that small flower of flesh moved ever so slightly, and he found himself becoming aroused. 

The man, of course, observed all of Liu Yong's reactions but didn't address them for now. He tapped his heel on the floor tiles a few times, and surprisingly, the four tiles where Number Sixteen was kneeling rose to form a waist-high platform. Number Sixteen's raised buttocks were now conveniently at the man's hand level. 

The man slapped Number Sixteen's buttocks, and Number Sixteen immediately relaxed obediently. His light brown anus twitched twice, revealing a small gap from which the lubricant inside began to leak out slowly. 

The man placed two fingers at the anal opening and, without hesitation, inserted them directly and began to stir. 

"The lubrication is acceptable. How much did you use today?" the man asked, moving his fingers around. 

"In response to Master, this slave currently has 200 milliliters of lubricant in his belly." 

Number Sixteen's voice remained calm, but his anus kept twitching with the master's movements. More and more lubricant flowed out, leaving his entire lower body wet and slick. 

"From tomorrow on, you'll need to do this too. Understood?" the man said while manipulating Number Sixteen's anus and explaining to Liu Yong. 

"This lowly slave understands!" This time, Liu Yong's response was finally quick and accurate, clearly intimidated by the whip's threat. 

The next step was to test the anus's contraction strength. 

This time, instead of using his fingers, the man adjusted Number Sixteen's position, tilting his buttocks over the edge of the platform. He then took out a glass rod less than two centimeters in diameter, inserted it into Number Sixteen's anus, simply said "hold it," and let go. 

The glass rod was very smooth, with a counterweight attached to the lower end. Number Sixteen now relied solely on his anal muscle contraction to keep the glass rod balanced. 

Although the glass rod was still sliding down very slowly, the fact that he could hold such a smooth rod steadily showed that handling a man's penis would be no problem at all. 

Having tested contraction, it was time to examine expansion ability. 

By now, Liu Yong was almost mesmerized by Number Sixteen's anus. His own anus was constantly opening and closing, and his penis was fully erect and hard, with precum slowly leaking from the urethra. 

Liu Yong thought this was leftover lubricant from the earlier enema, unaware that the club's training lubricants were specially formulated. Besides excellent lubrication, they also stimulated the growth of internal mucosal nerves and blood vessels, increasing sensitivity. 

In other words, without realizing it, Liu Yong's intestines, urethra, and bladder had already been modified. This modification would continue with each enema and bladder wash until Liu Yong became a complete slut who would orgasm just from someone blowing air on his anus. 

To give Liu Yong a clearer view, the man stood beside Number Sixteen throughout. He removed the half-fallen glass rod and added another 200 milliliters of lubricant for Number Sixteen. Then he coated his own hand and forearm with a thick layer of lubricant. 

Liu Yong watched nervously from his kneeling position nearby. Based on the man's actions and previous explanations, he could guess that fisting training was about to begin. 

The man rotated half his hand inside Number Sixteen's intestines a few times. Number Sixteen immediately began moaning "Ah... ah..." His voice was full of excitement without any pain, clearly showing that this level of training was routine for him. 

The man used his other hand to strike Number Sixteen's buttocks hard several times, signaling him to spread his ass even wider. These slaps were forceful, immediately causing Number Sixteen's buttocks to redden with blood rush, looking very enticing. Liu Yong, kneeling not far away, somehow found himself wishing those slaps were landing on his own ass.
