Please Call Me Teacher Xu

After a long day at work, Teacher Xu returned home. Seeing his beautiful wife set the meal on the table, he smiled with satisfaction.

At the table, his sister-in-law stretched out a shapely, pale leg and quietly kicked Xu Xian. Leaning close to his ear, she whispered:

"Brother-in-law, come to my room again tonight." Teacher Xu looked a little troubled. Doing this every night was exhausting.

Late that night, with everything quiet, the light in his sister-in-law's room was still on. Teacher Xu pushed the door open and walked over to the girl. As he smelled the fragrance of her body wash, he fell into deep thought. After a long moment, he pointed at the failing test paper beneath her hand and said irritably, "You're so dumb! You can't even solve a question this simple!"
