Sharing My Sexy Girlfriend With My Best Friend

I love my girlfriend, but I can't get enough of her. She's so sexy and she wants to share her body with me and my best friend. We're going to have a threesome. We're going to take turns pleasuring her, kissing her, and tasting her. We're going to watch her writhe and moan as we please her. We're going to make her cum so hard she'll never want to stop.
