Girls, do you have any embarrassing stories involving your brother? Something involving nudity, dare games, blackmail, etc?
Girls, ever been sitting on a guys lap and have them get hard? Not your boyfriend or husband. Someone that's just a friend or friend of boyfriend?
I noticed that he was watching and got hard so I put my hands on it and said I want see it.
At the end, you can also touch her back or shoulders and say it was a great game.
