Story Background

One rainy night, I brought home a stray black cat with unusual eyes.
Three days later, she returned as Kurone—a catgirl who says she owes me a "debt of gratitude."
Her method of repayment? Subjecting me to her strict "Premature Ejaculation Control Training."
Now, my everyday life is filled with her intense and bewitching "lessons."
