When I was in the 4th grade my class had a Teacher's assistant who was a Senior at a nearby High School. She would come by everyday for an hour or so and help the teacher with tutoring us and grading papers. Every now and then the teacher would let her teach a lesson and as a rowdy 4th grade boy I made sure to give our young assistant a hard time. The next year she became a lunch time proctor at my school so for 1 more year I gave her a hard time during lunch.
Fast forward I am now 20 years old and I'm hanging out in my apartment complex when this woman recognizes me, it was the teacher's assistant from 4th grade. I was shocked that she recognized me and she said she could never forget me because I gave her such a hard time. Well it turns out that she likes to party and for a while was hanging out with my friends and I. I would always say to her 'I bet you didn't think you'd be hanging out with me when I was in 4th grade' and she'd say something like 'that's how sad my life is I'm hanging out with the 18-20 year old crowd'.
Fast forward again and her and I end up in a sexual situation where she gave me a hand job and I ejaculated on her face. It's so crazy to think about because there is no way she would have looked at me in fourth or fifth grade, this short, skinny, annoying kid with messy hair that seemed to never be combed and thought 'one day I'm going have my hand around his 'you know what' and I'll be jacking him off' but that's what happened. I will always think about that short 15 minute encounter as the most unlikely scenario that ever came true.
