Watano Yui, the wife of a man who greedies with wet body on rainy days

"Please... Don't tell your husband that you are..." Yui, the wives who suffered from sexlessness, was seen by his brother-in-law as a lonely son-in-law and had a relationship with him. Even if you know that it is a bad thing, your body will be exposed to the need as a woman, and instincts will ask for meat bars. Yui, who can't get out of the muddy waters of adultery and incest, is finally able to take his brother-in-law's sperm into a hot barrel.
