Shhh! Extremely Blatant Action! I've Never Done Anything Like That!

Extremely blatant action by me. I've never done anything like this! But I just wanted to see how my bare cunt was received by my stepsister's husband. The three of us sit in the living room and watch TV. My stepsister was very engrossed in a phone call and I was lying on the couch bored and playing around with my bare cunt a bit. My husband was sitting right next to me. I smiled at him invitingly. It should only be a game. But then I saw the huge bulge in his pants. But then something incredible happens!
