I love to wank in front of my wife.
One day coming home from work early we had the house to ourselves. After a while I said to her I was going to get changed, then added I would also be getting naked and having a wank.
Her eyes widened, she was upstairs like a shot, video camera in hand. Soon I was cumming all over my chest. She has watched it back many times, and has promised to return the favour with her own peformance.
