Chapter 13 Biology teacher’s punishment: How about slapping your butt with a ruler?

"Bai Yi, 71."

"Ling Er, 94."

"Ke Lin, 44." Zhang Qinghe frowned. The pressure in the classroom dropped. Ke Lin didn't dare to look at Zhang Qinghe, so he buried his head deep.

Ke Lin hadn't been putting his mind on studying recently. He was in heat all day and night. His grades were originally bad, but this time it was especially so. He could only hope that Zhang Qinghe would take their relationship into consideration and let him go.

How could Zhang Qinghe let Ke Lin go? Although he was forced to come to the school and teach, he refused to allow his class to fail!

Unforgivable!

The atmosphere became more and more rigid, and the air classroom seemed to get extremely heavy, making people unable to breathe.

At this moment, the school bell rang. Ke Lin exhaled in relief.

Zhang Qinghe sneered and said, "Ke Lin, follow me to the office."

Ke Lin's mouth dropped in shock. His mouth was open so wide that you could fit an egg in it. People around him showed him sympathy, "Mr. Zhang seldom cares about us, but if you fail the exam, he will become a demon king."

"Of course, only for the last in class."

"I hope you can come back before lunch."

"Good luck."

Ke Lin could only flatten his mouth, looking as if he had eaten a bittergourd. His legs trembled as he stiffly followed Zhang Qinghe back to his office.

As soon as he entered the door, Zhang Qinghe took off his suit jacket, wearing only a shirt. His eyes were turbulent like thunder and his stare made Ke Lin's legs soften.

"Go and lock the door." Zhang Qinghe leaned on the desk, his bangs covering his gaze, and ordered him.

All the hair on Ke Lin's body stood up and he felt that Zhang Qinghe was thinking about something terrible. He moved slowly to close the door, feeling a scorching gaze behind him. It blatantly sweeped his body, as if it could pass through his clothes and caress his body.

Undoubtedly, Ke Lin's lust was ignited and the delicate and small cock stood tremblingly, pitching a small tent in his trousers.

As a veteran that had plenty of experience, Zhang Qinghe knew that this originally innocent young boy had been trained by others ever since that day. He stretched out his tongue and licked the corner of his mouth. He was very curious how the current Ke Lin tasted.

"Why don't you explain this to me?" Zhang Qinghe raised the paper in his hand with a rascally smile on his face. The most unfair thing was that even Zhang Qinghe's smile looked damn handsome.

Ke Lin was fascinated by Zhang Qinghe at the moment. He looked at the other party, only to feel that his legs were weak. He slowly moved over, letting himself lean on Zhang Qinghe's body. One leg grinded against Zhang Qinghe's thigh and even inserted itself between Zhang Qinghe's legs, using his thigh to arouse Zhang Qinghe's cock.

Under this kind of teasing, Zhang Qinghe's cock became more scorching hot and swelled a bit.

Zhang Qinghe hugged Ke Lin and made him lie on the table with his hips cocked high. Ke Lin thought he wanted to eat his back hole, so he blushed and shook his ass, his holes watering.

Zhang Qinghe squinted his eyes, restrained the desire in his heart and took the ruler instead. Then, he continuously slapped Ke Lin's ass.

"Ah!" Zhang Qinghe didn't hit hard. Ke Lin just felt a little uncomfortable because the other party kept hitting that unspeakable place again and again. Gradually, apart from shame, a feeling of pain mixed with numbness swept across Ke Lin.

Zhang Qinghe wasn't just hitting Ke Lin's butt, his other hand was pumping Ke Lin's meat stick back and forth. His nails played with the hole on the tip of Ke Lin's penis and the licentious fluid flowed down his fingers.

"Uncomfortable, let me go, teacher, don't hit me anymore..." Ke Lin couldn't tell whether he was happy or uncomfortable, as if a cat was scratching in his heart. It was uncomfortable if it scratched, but it was also itchy if it didn't.

"Teacher, ah, please, it's so uncomfortable, ha, no more, I'm going to shoot..."

Zhang Qinghe chuckled and deliberately spoke by Ke Lin's ear, "I have never seen such a licentious person like you, saying that it is uncomfortable, while you actually like me treating you like this."

"Or did you deliberately score so badly on the test, wanting me to punish you? 44 points, I'll only stop after it hits 56." Zhang Qinghe raised the last syllable, making Ke Lin's go soft. He liked it very much.

Before Ke Lin could answer, Zhang Qinghe squeezed his cock lightly and it immediately shot. Ke Lin's whole body went numb and soft, "No more, I've already shot, teacher, my back hole wants it, help me, teacher, don't hit me anymore, it hurts….."

Zhang Qinghe turned a deaf ear, but the ruler in his hand shifted its direction and started hitting Ke Lin's back hole. The delicate back hole softened from being hit repeatedly and the mouth of the hole squirmed and gaped open and closed.

"Ah, it hurts, teacher, don't hit that place, it will break..."

"Does it hurt or does it feel good?" The deliberately lowered voice made Ke Lin feel like he couldn't have enough. He rocked his hips and greeted the ruler, tears uncontrollably flowing down his eyes.

"It hurts but it feels good too, ah, so hot, it's like my butt's on fire, so uncomfortable..."

Zhang Qinghe took a pen and applied lubricant on it. Ke Lin turned around in confusion because he couldn't see what Zhang Qinghe was doing. He didn't know why the other party stopped moving.

Zhang Qinghe slammed the pen into that little mouth and thrusted, causing a lot of water to splash out. Ke Lin sighed contentedly. When the back hole got used to the pen's movement, he began to dislike the small pen and twisted his body in dissatisfaction and ate the whole pen.

"I want Teacher's big cock, it's so uncomfortable, come in, Teacher….." He perked his ass and invited the man in, kneading and pulling on his nipples with his hands, the accumulated pleasure coursed through his body.

Zhang Qinghe didn't seem to see this. He stuffed the second, third, and even the fourth pen in, took out another test paper, then handed it to Ke Lin along with a pen and said, "I'll fuck you after you finish. If you fail, then I'll get you another paper."

Ke Lin was stunned. He thought that Zhang Qinghe had asked him to come for a booty call, but he didn't expect it to be to answer exam questions. But when he thought of Zhang Qinghe holding a ruler just now, he revealed a longing expression. Now that the arrow has been nocked, will it be shot?
