Lustful young man fucked his best friend's wife while traveling together

Everything was fine until I went on a hot springs trip with my best friend and his wife, until I saw that scene. Through the slightly opened shoji, I saw Naoya's wife burying her face in his crotch. Even when she noticed me, she kept licking me and just stared at me like: “Look at me, I'm so vulgar.” In the middle of a drunken night, a soft feeling came over me and a sweet scent filled me “Do you want to hug me?” I lost control and over and over again exchanged dirty jokes with my best friend's wife.
