First time kicking a guy in his balls (true story)

I used to have this boyfriend who I liked to playfight with, and sometimes things would get pretty rough but I'd play dirty so I'd win. Then one day we were in his moms new house, they hadn't moved in the furniture yet and we were bored so we began wrestling. At first we were laughing but then he managed to pin me down and started to boast like he was so big and bad for it. It was a first, he didn't usually get that far to be able to pin me down, but him laughing and boasting while keeping me pinned down made me a little ticked off so I lifted my leg up and donkey kicked him and all I heard was an "AAAHHHWWWWW!!!!" and he dropped to the ground holding himself. I started laughing and asked him "whats wrong? I thought you were all tough?" It was kinda funny, I couldn't help but to laugh at him. He was curled up and breathing hard while I stood over him shaking my head saying "well, now you know not to pin me down dont you." After like 5 minutes he sat up and told me I got lucky with landing that kick right in the balls
