Just go slow, the build up will be worth it, when you meet this lover, you both should feel comfortable with him. Have him over for dinner, and them soft play, working towards the build up. One thing to make sure that you get all your kinks out in the open so they do not surprise her, if you want to eat her out after she has sex, or watching them play, this way if you want to to something its not a surprise.!!!! Good Luck!!!!
