Misora, who is about to take university entrance exams, goes to Tokyo for her exams. She decides to live in the apartment where her older sister and her husband live for a while. Her older sister, who is still working after her marriage, has a hard time getting along with her husband. Seeing her brother-in-law like that, Misora decided to use her brother-in-law as revenge for being disappointed by her boyfriend. You can do whatever you want, such as a night crawling blowjob right next to her sister sleeping, or pressing H with a buckwheat as soon as her sister is drunk. At some point, the two of them start to feel the excitement of stealing her sister's (her wife's) eyes and doing naughty things...
