A story about a married woman with injuries to both hands and legs who is cared for by her husband's younger brother who reveals his ulterior motives.

After three months of complete recovery after breaking both arms and legs, Saki is forced to leave the hospital and return home due to the boring hospital stay. Worried about Saki, who can't do anything by herself yet, her husband asks her younger brother, a college student, to take care of her as a part-time job during summer vacation. Saki is unable to use her arms or legs because she is firmly in a cast, and cannot do anything without the help of her brother-in-law, such as going out in a wheelchair, eating, going to the toilet, and taking a bath. In such a situation, Saki's brother-in-law begins to think that no matter what he does, he can't resist and does whatever he wants in the name of "taking care of her." ``You can't run away from me.'' Until the sister-in-law is completely healed, she will masturbate! ! !
