I don't know how many times I inserted it, and my mother's bottom was wet. Suddenly, my mother hugged me tightly, and her vagina contracted violently a few times. My mother seemed to have exhausted all her strength, and it softened again. I don't know what's going on, or was it so deeply inserted into the moderate rain. I could no longer resist the urge to burst out, and a stream of semen shot into the depths of my mother's vagina like a bullet.
