Incest stories between brothers and sisters are probably no longer strange in the land of JAV. Since they have been together since childhood, the two brothers understand each other very well, which means that there is a vague affection between them that only the two of them can understand. As for the older brother, he is old and does not have a wife, so he often has desires for women. To satisfy those desires, he always clumsily peeked at his sister while she was sleeping, and of course she knew this. Until the two of them couldn't stand the relationship going on like this anymore, they decided to go one step further, the two of them carried out incest together in the hope of finding a new path for this shady relationship.
