Ando Tetsuo, 46 and single. He somehow makes ends meet thanks to the inherited house from his parents. Under him is a woman, Ando Noriko, 32, who is his sister-in-law. Ever since he half-forcibly made her suck it at a memorial service half a year ago, their relationship began. And today... after Noriko's visit, they fuck using 48 techniques until evening. Though he has always been told he is an incompetent older brother, it seems that his skills in this area are exceptional. Noriko also seems ready to be thoroughly embraced... (From the first episode)
