水下颜面骑乘，女性studen在浴缸里用磨砂刷擦洗导师，她用阴户和屁股淹没了导师

The female student is wearing only panties, puts a collar and leash on the tutor, and puts the tutor in the bathtub filled with water. The Student says to the tutor, "Teacher, I'll wash your body for you, hehehe," and scrubs the tutor's face with a deck brush, "hahaha." The Student tells the tutor, "I'll wash you better," and laughs as she submerges the tutor underwater with the deck brush. The Student asks the tutor, "How many seconds can you stay underwater, teacher? hehehe," and counts as she submerges the tutor's face with her feet, pussy, and facesitting. The Student makes the tutor hold a short hose in her mouth and says, "You can stay underwater forever with this, right, hahaha," and submerges the tutor. However, the Student teases the tutor by blocking the opening of the hose with her hand and pouring water into the hose.
