A fascinating girl, Hibiki-chan, who seems to sprinkle intense pheromones wherever she is. After returning to her parents' house after a long time, she seems to have more sex appeal and libido than before, and the spearhead of her surplus libido goes to her adolescent brother, and she is a bottomless nymphomaniac who lusts for her brother's virgin dick. My sister's runaway will not stop until it feels good. Free trial points for the first time!
