Kotone-chan, the cute sister who recently started working at a men's esthetician, seems to be secretly practicing, and today she's having her real brother become a practice subject for a full-fledged training session! When the brother is massaged with her smile, he naturally gets excited and erects, and he won't calm down unless he ejaculates. The brother begs Kotone-chan for something he shouldn't, and somehow he thrusts his cock into the depths of her vagina and creampies her.
