My husband Darren's voice made me jump. He laughed as he watched me wanking, and immediately stopped me from my pleasure. I was so embarrassed. "Don't stop now. I know where you were and I wanted to watch you cum. You'd never do it for me would you? So I have to get off on watching you secretly. Its not the first time I seen this you know?" He was laughing to himself, and looked so damned pleased with my discomfort.
