My husband's younger brother, Masashi-kun, who was living with me because he was a ronin, protected me when I dropped a pot. - While both arms were injured... - I was filled with guilt and wanted to do anything for him, but Masashi-kun asked me to have sex with him in the mouth. - The words ``If it's just the mouth, it's not cheating.'' I wanted to escape from the guilt and my mind went blank with the sight of his magnificent cock, and before I knew it, I had it in my mouth and became addicted to Masashi-kun's cock.
