HND-990 A horny niece (my brother's daughter) who insists on having kids and getting married based on a childhood promise.

"Let's get married in ten years." My niece Rika, whom I hadn't seen in a long time, had been believing in that 'promise' all along... I never thought that my niece's confession from ten years ago was serious... Her cuteness hasn't changed, but now an adult, Rika has an abnormally strong sex drive... She repeatedly demanded sex for the purpose of making children. Her feelings for me and her lust exploded! How many times did she milk me dry while my brother was away...? I've already surpassed the limits of my dick, repeating internal ejaculations and orgasms.
