In this steamy video, we see Zhang Asahis latest work at Taiwan University, where he plays the role of a Calculus teacher with big tits and a blockboard erasing girl. The scene opens with the teacher standing in front of a classroom, wearing a tight black dress and heels, and looking at her students with a seductive gaze. Suddenly, a girl in a short skirt and a top that barely covers her ample cleavage approaches her and asks for help with a difficult calculus problem. The teacher, who is clearly flattered by the attention, agrees to help the girl, but only if she can return the favor by showing her gratitude in a more intimate way. The girl agrees, and the two move to a more private area of the classroom where they can be more comfortable. As they start to get down to business, the teacher's big tits bounce and jiggle with each thrust of her hand, and the girl can't help but be mesmerized by their beauty.
