On the occasion of the summer break, my cousin Yuna Ogura came from Tokyo to visit my family. Seeing her at the age of puberty, she had many curiosities about physiology that no one answered, only knowing to masturbate at night, which made me feel sorry for her. With all the responsibility of an older brother, I decided to teach her some very basic lessons about making love, helping her truly satisfy herself with my magical hands and penis. With her lasciviousness and excitement, my cousin quickly absorbed the lessons, and we had sex many times during the 3 days she visited, fucking her pussy made me extremely delighted and passionate. I will always remember those wonderful summer days with my cousin.
