After graduating from university, my older brother got a job at a large company and lived alone. However, after a year passed, he spent his days working hard and became a so-called "company slave". Seeing such a changed brother, the girl's younger sister encouraged her with her breasts, saying, "I don't want to be like this brother." A brother and sister story for only 3 days where the mother's love of the sister and the big breasts of the H cup gently wrap the useless brother.
