Awful. My little sister has learned how to flash. And without knowing how to control it, she lets her vulva stick out, which honestly, as her brother, I can't stand. She innocently begs, 'Show me you ejaculating♪' while flashing her panties (and sometimes her genitals) and teasing me with cute lewd language... Desperately accepting the limit-pushing, fully erect cock into her vulva while sweating! 'Big Brother♪' is frequently heard in Minami Hatsukawa's debut as a little sister, in a full-force teasing situation!
