My girlfriend's younger sister, who I met for the first time, was a sickly cute JK. When she was gone, she came out and told me about her special fetish for feeling something deep in her throat, and seduced me by licking her fingers. She took off my pants to tease me, and took my dick in her mouth! She suddenly took my dick deep in her throat! I couldn't resist the self-deep throating that I had never experienced before, and when I ejaculated deep in her throat, she swallowed it with a gurgle! It seems that my dick-addicted, mentally unstable younger sister liked my big dick. From that day on, I had her swallow my self-deep throating many times in secret.
