The protagonist has 2 sisters, who are working as a model and an idol. In order to help them lessen the burden of supporting the family, he takes care of the housework—e.g., cooking, laundry, cleaning... However, he is still a growing boy and so holds some desires for his alluring sisters. One time, while engrossed in masturbating using their swimsuit poster, he is discovered by his older sister. Unexpectedly, she only smiles and says that she will help him with it. And so, they cross the siblings line. Furthermore, even his younger sister, who notices something going on, starts to make advances to him. [Translated from Official site]
