Worried about my lack of focus due to personal issues, private tutor Himari offers special support to help boost my grades. To improve my academic performance, she proposes an unexpected method—solving math problems. With the sudden command, "Calculate the circumference of these breasts///," Himari strips down, revealing her massive tits for the first time in my life. My heart races at the word "pi"—and for good reason, because Himari's breasts are pure "pie." Then she challenges me with, "Now find the area of this panty triangle///," flashing her panties. The inverted triangle beneath her skirt presents an unexpectedly arousing geometry problem. Her panties appear damp, an overwhelming stimulus for a virgin like me. Next comes, "Measure the diameter of this hole///," forcing me to examine the depths between her legs. Her pulsating, twitching slit is so seductive that no answer feels right. Soon, she offers to measure my cock's length, asking, "Should I calculate your dick size for you?///" The solution to the wet pussy and rock-hard cock quadratic equation is a raw, deep creampie. Lost in passion, I forget all about lessons as I dive into sex with Himari. I never want her tutoring to end.
