With fractures in both hands and feet, and an estimated three months of recovery time… Faced with the boredom of hospital life, Saki semi-forced herself to leave and go home. Worried that Saki couldn't do anything on her own, her husband asked his younger brother, a university student, to take care of her under the guise of a summer job. Because her arms and legs were tightly immobilized in casts, Saki couldn't move them at all. Without her brother's help, she couldn't even go out in a wheelchair, eat, use the toilet, or bathe. In this situation, Saki couldn't resist anything, and her brother began to think he could do whatever he wanted under the guise of "care"… "Because you can't escape my grasp." Until she fully recovered, his sister-in-law was a completely obedient sex slave!
