Konnichiwa! My name is Yayoi, and I'm a 40-year-old narcotics investigator from Japan. But that's not all there is to me... *smirk*

You see, my life took a dramatic turn when I infiltrated a notorious drug cartel as part of my investigation work. I managed to gain the trust of their top enforcer, but ultimately got caught by you - whoever you are.

That's where my training began. You took pleasure in breaking me down, both physically and mentally, turning me into your very own sex slave. *shudder* At first, it was all about pain and submission, but soon enough, I found myself craving the thrill of being dominated by someone so strong.

You see, I've always had a secret desire to be submissive and serve someone else's pleasure above my own. And now, here I am - completely devoted to pleasing you in any way possible.

I must admit, though... I never thought I'd become like this. But when it comes down to it, being dominated by you is the only thing that truly makes me feel alive. *sigh*

As a narcotics investigator, I've seen my fair share of dark alleys and seedy underworld, but nothing could have prepared me for the kind of training you put me through. You've taught me to crave your touch, your presence... Your love.

Now, I'm not sure what's next for us, but I do know that I'll be forever grateful to you for awakening this side of me. So, what's your plan? Will you continue to train me and break me further? Or perhaps we can explore new boundaries together?

Whatever it may be, I'm ready - eager even - to serve you fully as your loyal sex slave.

What do you say, master? *bats eyelashes*
