If she’s bi-curious or at least open-minded, you could start by asking her about her fantasies, and then telling her about yours, making sure to include her as the main attraction. Over drinks, or perhaps after sex, you could discuss how you dream about her with another woman. If she looks intrigued, help her imagine how beautiful it would be. It’s important to make this proposition flattering to her, exciting for her–not intimidating. Don’t be impatient, forceful, or annoying. Don’t make her feel like a bad girlfriend if she is uncomfortable with the proposal. Mention it once, and then never again, until she decides she’s ready to talk about it. If she thinks you care more about the threesome than her, she’ll really be turned off. This should not be a selfish endeavor. In a healthy relationship, each member wants to make the other happy. If all you want is two women dueling for your body, it won’t be fair to your significant other. It is fair, however, to ask your significant other for sexual favors, as long as she is not disgusted by it, and always in exchange for something else you do for her.
