During the summer vacation, my cousin Nishinomiya Konomi came from Tokyo to visit my family. Seeing my teenage sister having many physiological curiosities that no one could answer, only knowing how to masturbate at night made me feel very sorry for her. With all the responsibility of an older brother, I decided to teach my cousin the basic lessons about sex, helping her to be truly satisfied with my pussy and magical hands. With her lust and excitement, my cousin learned the lessons very quickly, we fucked each other many times during the 3 days she visited, being able to fuck my cousin's pussy made me extremely excited and passionate. I will always remember the wonderful summer days with my cousin.
