Spanish teacher in junior high school. She was in her mid twenties. She wasn't very pretty, but OMG that ass.

Kids from other classes would stand outside our classroom door and peek through the little rectangle window just to catch a glimpse of that ass.
One day when she was mad at the class she stood next to my desk and I swear her ass poked out so much that it was sitting on my desk. Instant woody.

Another time she was walking around the classroom in these skintight black pants. I was laying down with my arm hanging off the edge of my desk and when she walked by her ass brushed up against my hand. That shit was like jello son. She didn't even look back at me or say anything. She just kept walking. I couldn't get her out of my head for the rest of the day.
About a week before we graduated, we found out that she got pregnant. :'(
