I came home early from work one day and heard some noise in the bedroom. I walked down the hall and saw my wife riding some stud's cock. I stayed in the hall and watched. She kept telling him how good his big cock felt in her pussy and that she wanted him to cum inside her. This went on for twenty minutes then he started to cum inside her. When he did and she felt his load shooting inside her pussy, she went into an intense orgasm. When she finished she got off his cock and went to suck him off. That is when I saw how big he was. He was as thick as her wrist and at least 10". I left and came back at my normal time. When I got home, she went on as if nothing had happened. I fucked her later that night and her pussy was still loose and his cum was still inside her.
