Rihanna Black has geometry problems, so she takes private lessons. The teacher tries to explain the 18 cm segment to her, but she doesnt understand. Finally, he realizes there is only one way out, and that is taking his dick out of his pants and showing her the 18 cm in practice. Rihanna Black feels amazed at first but then agrees this is the best way of studying and teaching.
