"Today we are discussing the application of trigonometric functions. Please listen carefully, Xiong Xue."
Xiong Lili bit her lip, trying hard to suppress her smile, and nodded in a serious manner:
"Damn it, teacher."
She tried her best to look obedient, but the slightly raised corners of her mouth revealed her inner joy.
She really loves cosplay, even to the point of obsession. Now that the man in front of her can possess her without any care, but is willing to play these childish role-playing games with her, a warm current surges in her heart.
Ye Lang opened the textbook and said in a serious tone:
“First, let’s look at this question.
An isosceles triangle has a base of one meter, two sides of equal length, and an included angle of ninety degrees. What is the area of the isosceles triangle?
Xiong Lili was slightly stunned, not knowing why Ye Lang took the cosplay so seriously, but she still cooperated and thought about it, pretending to think about the question.
But Ye Lang interrupted her thoughts and tapped her head lightly with his pointer:
"Please come to the table and demonstrate the steps to solve the problem."
Xiong Lili was stunned, and her cheeks flushed instantly. She finally understood what this man was up to.
But she did not refuse and climbed onto the table obediently. Her tender little feet stepped on the smooth wooden table. Her heart beat faster involuntarily. Then she slowly spread her legs and formed an isosceles right triangle as required by the question.
Ye Lang looked at her serious expression, a smile flashed in his eyes, then he frowned, took out the pointer and gently stroked her slightly trembling legs.
Xiong Lili couldn't help but let out a soft hum, her body trembling slightly, but she still tried hard to endure the numbness and tried her best to maintain her posture.
"Very good. Next, let's calculate the area of the triangle."
Ye Lang whispered, and as he spoke, he gently slid the pointer across her tense knees.
"Your legs are the two sides of this triangle. Now, tell me how tall are you?"
Xiong Lili's cheeks were already red to her ears. She could feel Ye Lang's gaze and the slight touch of the pointer intertwined together, and it was not just the problem itself that made her heart beat faster.
She bit her lips and whispered as softly as a mosquito:
"Height... Height is half a meter."
"Really? Teacher, I don't believe it. I have to measure it myself to be sure."
As he spoke, Ye Lang slowly leaned over and pointed his pointer upwards from the tabletop, as if he were really measuring a value that didn't exist.
Xiong Lili's body trembled slightly, and her breathing became rapid. She almost forgot that she was still maintaining that embarrassing posture.
Finally, Ye Lang stopped at... holding the teaching stick, staring at her with burning eyes:
"Xiong Xue's answer is correct. It is indeed half a meter."
He whispered, his pointer trembling slightly, and his eyes were filled with a hint of teasing and tenderness.
Xiong Lili couldn't hold it in any longer and let out a soft cry, nearly collapsing. But Ye Lang held her up and chuckled softly, "This is just the beginning. Next, let's calculate the circumference."
His voice seemed to have magic, making her shy and irresistible, and she could only sink into the sweet game he set.
Xiong Lili's breathing became increasingly rapid, her legs trembling slightly, beads of sweat forming on her forehead, yet she bit her lip to prevent herself from making a sound. She tried to match his movements, as if at this moment she had truly solved the triangle in the puzzle, and he was the only one who could solve it.
In this way, the math teacher and the little succubus had an unconventional math class in the classroom.
They not only calculated the perimeter of the triangle, but also studied the aesthetic proportions of geometric shapes on the human body.
Ye Lang's teaching stick seemed to have come to life, gently moving across the little succubus's moving curves. Every touch seemed to be sketching a touching picture.
