Tang Tan was so drunk that he couldn't even see the faces clearly. He just felt that he was being dragged here by a huge force in a daze.

There was a familiar smell of various reagents mixed in the air.

Opening his eyes wide in unconscious struggle, his slightly cloudy pupils shrank suddenly.

He saw Xia Qu's eyes sparkling with deep eyes.

Suddenly, a strange excitement came to my heart.

Tang Qin achieved his goal. He finally managed to make Xia Qu endure until the fake mask showed expressions other than seriousness and calmness.

This is indeed the first time in Xia Qu's life, and no one has ever made him break his skills like this.

But Tang Qin didn't realize the heavy price.

"Let me tell you why you were brought here by me now. First, you ran to drink without telling me. Second, you were drunk after drinking. Third——"

Xia Qu dragged out the ending, took a deep breath to calm his rapid heartbeat, and then continued with a vicious voice.

"You are still going to call the hostess!"

The loud voice woke Tang Qin up completely. He didn't expect Xia Qu to be so aggressive towards him.

His eyes widened, and he struggled with his hands and feet. Tang Tan realized that this time, not only his hands were tied behind the chair, but his feet were tied to the chair legs.

And Xia Qu moved a chair and sat directly opposite him, with his hands on his knees, so he turned into a posture with his feet wide open and his chest open facing Xia Qu.

"It's none of your business if I drink! It's none of your business if I'm going to call Miss!"

Tang Tan yelled at Xia Qu with a hoarse voice without admitting defeat.

The remaining half of reason in Xia Qu's eyes disappeared at once, replaced by a dangerous character with his eyes narrowed into two slits.

Reaching forward, he quickly untied Tang Tan's tie, strangled it around Tang Tan's mouth, and tied it tightly around his head.

"Get lost—" Tang Tan yelled indistinctly.

How could he let Xia Qu succeed so easily? He kept shaking his head violently, as if he was about to throw off his tie, but Tang Tan was as limp as a puddle of water when he was drunk, so Xia Qu couldn't help it. He did it easily.

Looking at Tang Tan who was blushing and blocked from speaking, Xia Qu nodded slightly.

"Tonight I was going to teach you how to identify and use these chemical experiment supplies, it seems that we can only entertain and teach."

Xia Qu's smile looked a little scary after the tenderness had completely faded away.

With cold fingers, he unbuttoned Tang Tan's white shirt little by little, revealing a chest that was reddened by drunkenness, and the two cherries on it were much redder than usual, looking extremely attractive.

Xia Qu got up and took out two T-shaped clips from the neatly arranged test equipment, put them in front of Tang Qin's wide-open eyes, and opened his palms so that he could see clearly.

"The water-stop clamp is used to clamp the rubber tube so that the two devices are no longer connected, and neither liquid nor gas can pass through."

After he finished speaking, he took a rubber tube to demonstrate, and only heard a snap, and the water-stop clamp firmly bit the rubber tube under the action of the spring.

When Xia Qu took off the spring clip and approached him with the rubber tube together, Tang Qin's expression was mixed with a trace of undetectable fear in the doubt.

"You come to feel it, um, considering that you can't move your hands, why not use other places..."

Xia Qu's smile was a bit cloudy, and his hands were merciless, and the two Zhishui caught Tang Tan's nipples with two slaps.

Then he kept unbuttoning his pants, pulling down his underwear, and tightly wrapped the rubber tube around the root of Tang Tan's dick.

"No woo... hiss... um... um..."

Tang Tan struggled again, the redness on his face spread to his neck.

But this time it was obviously reduced a lot, he only felt that the nipples on his chest were inconceivably painful, and the root of his dick was even more painful and numb.

So the original cry gradually turned into a cry of pain.

Sensibility was controlled by the pain, and Tang Qin didn't notice at all that Xia Qu had already stretched out his hand in the air, and was about to caress his pitiful cock that was trembling due to being restrained.
