Emi-chan, a pure and innocent younger sister who has a straight line of love for her brother. As soon as I got home from school, I went to my brother's room and played with him on the bed. Suddenly, Emi-chan, who looked as if she had decided something, lifted up her skirt and shyly showed her striped bread to her brother, saying, "I think this striped bread old man will be pleased." The delighted brother pushes Emi-chan down vigorously and rubs the erected lower body! Emi-chan becomes bold as she is delighted that her brother is excited about herself. A heart-pounding youth love story for my brother and sister.
