Both arms and legs broken, with a full recovery time of three months... Saki decides to leave the hospital halfway through her boring hospital life and return home. Worried about Saki, who still can't do anything on her own, her husband asks his college student younger brother to take care of her as a summer job. Saki, whose arms and legs are tightly fixed in casts, can't do anything without her brother-in-law's help, such as going out in a wheelchair, eating, going to the toilet, and taking a bath. In such a situation, Saki can't resist anything, and her brother-in-law begins to think that he can do whatever he wants under the guise of "taking care of her"... "You can't escape from me," until she fully recovers, her sister-in-law is a flesh masturbation tool that does whatever he wants!!!
