saeki nana, the miserable older brother and wife.

When he went to Tokyo on a business trip, Hideyuki came to stay with his newly married brother and wife four years older than him. What I saw in the love nest of my brother and wife who visited for the first time .... A sister-in-law who is drunk as if jealous of Hideyuki's existence, a newlywed couple who hears apart from the wall. They were too cruel for Hideyuki, who had not tasted the woman's body for a long time. A brother-in-law who loses reason while feeling blood flowing into the lower body. The existence of nana was no longer a subject of sex.
