When I was an 18-year old senior in high school, my girlfriend Anne Marie who was also eighteen, was struggling to get her math credits so she could graduate from high school and go on to college. Numbers came easy to me so it was hard for me to understand what she was struggling with and help her. It just seemed like she got easily frustrated and gave up.
One afternoon after her latest non-passing grade, we were hanging out and talking. She was again expressing her worry that she would never get it and be able to graduate. I thought about ways to help motivate Anne Marie and after she had dismissed every idea she came up with, I finally said, "What do your parents use to motivate you?"
Anne Marie paused and turned a little red as she struggled to answer. Finally, she said, "they spank me." She continued, "But that won't work in this situation."
My interest was piqued by this revelation. I said, "How do they do it?" Anne Marie clearly did not want to talk about it, but with her head down so she could avoid eye contact, mumbled, "they put me over my Dad's lap and he paddles me." I immediately blurted out, "Does he pull down your panties too?" She didn't say anything but just nodded yes.
My cock immediately began to harden as I pictured my girlfriend laying over her Dad's lap with her panties pulled down. She had a nice ass and my imagination ran wild at how much nicer it would be if it was bare.
I could think of nothing else as I worked on my homework that night.
The next day, I suggested to Anne Marie that we take a walk down a trail through a nearby park. We used this trail when we wanted a little privacy to make out, although due to her relatively conservative upbringing, we never did much more than kissing.
I took us to our usual spot and sat on a rock formation that was just like a stool. I looked at Anne Marie and said, "How badly to you want to pass math?"
Anne Marie immediately said, "I will do anything" That was the answer I was looking for.
"I have an idea that may seem a little unusual, but it seem worth consideration. I think your problem with math is that you get frustrated to quickly and you do not stick with it long enough to absorb the pieces you need to be able to solve a problem. My solution is that I will motivate you like your parents by spanking you."
Anne Marie looked at me like I was crazy but after a moment, said, "How would you do that?"
I answered, "You need to average 85 points per test for the rest of the semester to earn a passing grade. There are 5 quizzes and 2 tests that remain. Your typical score has been a little below 70 points. I propose to spank you for every point you are below the targeted level."
