Chapter 1: Physical Examination & Auction - Training a Muscular Fitness Instructor 

When Liu Yong opened his eyes again, he felt confused. He had just moved into the dormitory yesterday, prepared for the next day's classes, and gone to bed. But now he was certain that this room was not his single-person dorm. 

Then, he discovered an even more serious problem. He didn't have a habit of sleeping naked, but now all his clothes had disappeared. He was completely nude, tied up tightly, unable to move except for his head. 

"What's going on?" Liu Yong shouted in panic. After a few shouts, he saw a sliding door appear on the smooth wall, and two muscular men walked in. 

The two men wore black leather hoods on their heads, exposing only their eyes, mouths, and breathing holes at the nose. Their upper bodies were bare, bound with several black leather straps. Their nipples, the size of black grapes, were pierced with nipple rings. On their lower bodies, they wore only white G-string underwear, with their hairy, huge testicles exposed, full and swollen, swaying with their walking steps. 

"Where is this? What are you going to do?!" Liu Yong shouted even more frantically as he saw the naked men approaching. 

But the two men seemed not to hear him. They lifted him up and tied him to a large X-shaped iron frame made of steel pipes nearby. 

After confirming he was secured, they opened another door, revealing a conveyor belt inside. They hung the iron frame with Liu Yong on it like a sausage on the iron hooks of the conveyor belt. Ignoring Liu Yong's pleas for help and curses, they forcibly fixed a gag in his mouth, then closed the door. 

It wasn't completely dark behind the door. Liu Yong could vaguely see several other conveyor belts around, also with thick, sturdy metal hooks, reminding him of the meat processing plant in his hometown. However, at this moment, there was nothing hanging on the other hooks. 

Finally, when it stopped, he didn't know how long he had been moving forward. A bright light appeared above his head, then the iron hook began to lift him up, placing him in an empty room. 

The room wasn't very large, about ten square meters, but three of the walls were mirrors. Liu Yong saw his current state in the mirror and struggled once again, making muffled sounds through his gag. 

"Liu Yong, 28 years old, professional fitness instructor, height 188 cm, weight 86 kg..." A man wearing a white coat and also masked walked into the room, stood in front of Liu Yong, and began speaking, all about Liu Yong's personal information. 

"...Congratulations, you're about to say goodbye to your former life. From now on, you will exist only as a trainee sex slave." 

"F**k you, what the hell..." As soon as the gag was removed, Liu Yong started cursing, but he was gagged again after just one sentence. 

"As a sex slave, you don't need to express opinions. Now I'm going to give you the most basic examination. Behind the mirrors sit your potential buyers. If no one is willing to buy you as an exclusive sex slave, then we can only regretfully send you to the lower levels to be used in public toilets. I hope you can seize this opportunity and perform well." 

What?! Liu Yong was startled, instantly feeling a sense of shame at being ogled. He shook his head desperately in protest, but it was all ignored by the man. 

"As a sex slave, the most important thing is sexual function." The man said while putting on surgical gloves, grabbing Liu Yong's member, examining and measuring it back and forth like inspecting goods. At the same time, he intentionally stood to the side, seemingly to allow the audience behind the mirrors to see more clearly. 

"Length when flaccid is 12 cm, thick and straight, no significant curvature." Then he took a bottle from nearby, squeezed a lot of lubricant into his palm, and began to masturbate Liu Yong. 

The man's technique was very skillful. Even though Liu Yong resisted in his heart, he quickly responded, his member rising up like a giant dragon. 

"Penis sensitivity is above average, glans sensitivity is high, can undergo targeted training." The man pulled back the foreskin, rubbing the urethral opening, immediately hearing Liu Yong's uncontrollable moans. 

"Length when erect is 17.5 cm, belonging to the medium category. Testicles are full, feel above average. This expansion rate is quite good, allowing for more variety in play." 

The man fondled Liu Yong's two large testicles continuously. Just as Liu Yong felt he was about to ejaculate, the man let go of his penis and moved behind Liu Yong. 

The man adjusted the angle of the iron frame, laying Liu Yong's body flat, folding his legs up and apart, exposing the anus hidden between his firm buttocks. 

Liu Yong finally understood what he was facing and struggled desperately. 

But the frame was too sturdy, not even shaking. Instead, the man was annoyed by his movement, grabbed the exposed testicles, and squeezed hard. Liu Yong immediately let out a muffled scream of agony. 

"Since we haven't officially started the training yet, I can forgive this act of defiance. But if you dare to do it again, I'll give you an unforgettable lesson." The man's tone was calm, but it made Liu Yong feel a chill. Combined with the intense pain in his testicles, he had no choice but to calm down temporarily and not dare to move recklessly. 

"This sex slave seems to be very energetic, with a strong sense of shame. Training him will present some challenges and be interesting." The man continued to examine Liu Yong's body. 

"Body hair is quite abundant, with quite a bit of anal hair. Of course, if clients have special requirements, we will preserve it; otherwise, we will uniformly perform permanent hair removal." The man fiddled with the hair around the anus, grabbed the two buttocks with both hands, and spread them forcefully, exposing the tightly wrinkled flower more clearly to the camera. 

"The anus appears undamaged upon visual inspection, light in color, pink, a very good virgin ass." As the man introduced, the earpiece had already transmitted the bidding voices from the outside venue. After all, for a sex slave purely used for play, as long as the ass is good enough, that's sufficient. There's no need for other requirements to be too high. 

The man inserted one finger into Liu Yong's anus, unsurprisingly hearing fearful moans. 

The man added another finger, constantly thrusting while skillfully searching for the position of the prostate. Once found, he immediately pressed down. After a few presses, Liu Yong's moans changed tone, and his penis, which had softened due to the intense pain earlier, showed signs of revival. 

"Rectal temperature is relatively high, tightness is first-class, and sensitivity is also very good. Being able to obtain pleasure through the back from the start, I'm quite optimistic about the potential of this ass." 

"The amount of ejaculation is also an important evaluation criterion." The man didn't remove his fingers from Liu Yong's anus but continued to apply stronger stimulation to the prostate while his other hand began to masturbate him. 

Liu Yong had never experienced the pleasure surging from both front and back simultaneously. For a moment, he couldn't control his loud moans. Soon, his penis was standing tall, hard and dripping. 

The man nodded with satisfaction as he saw Liu Yong's testicles lift and his penis begin to twitch, knowing the time was almost right. He pinched the prostate with two fingers, and Liu Yong felt as if an electric current had transmitted directly from his anus to his penis. He couldn't help but let out a loud roar as semen spurted wildly. 

Seeing him ejaculate, the man immediately took a plastic small bottle that looked like a measuring cup from nearby and put it over Liu Yong's glans, not wasting a single drop. 

Liu Yong hadn't masturbated for a long time due to work stress, so this ejaculation was thick and plentiful. 

The man looked at the scale on the measuring cup and said with satisfaction, "Ejaculation volume 8.5 ml, considered good quality. If the buyer has a preference in this aspect, we can significantly increase the ejaculation volume through training." 

"Overall, this is a trainee sex slave rated above average." The man finished the examination and threw the gloves into the trash can. "You can start bidding now." 

Three minutes later, the bidding ended. The man's tone carried a hint of joy, obviously having received a good price. As Liu Yong's trainer, he would naturally get a considerable commission, though this was all irrelevant to Liu Yong now. 

The man returned Liu Yong to his original posture and sent him back to the conveyor belt. This time, however, he would face a full set of sex slave training.
