My extremely filthy friend www.reddit.com/u/red370 wrote this for me a couple years ago, so it's not new, but this audio series is one of my favorites that I have done. My current work is done in my studio and has SFX, and this is lacking that, but it's still fantastic.
The original title of the series (I don't have enough characters to type it all in the title field) is "How the Alpha Made Me His Submissive Whore."
Synopsis: This is my whorigin story. I have been cheating on my husband during our whole relationship, because right before our first date, my brother's best friend got jealous of me seeing someone, and his primal instincts took over. I got the hardest fucking of my life, and he made me his submissive whore. He claimed me before my husband could.
