I thought this was just going to be a step-Mom and step-son weekend! You know how I feel about your girlfriend, and I am definitely not thrilled that you invited her yourself! You come with some exciting news...YOU'RE GETTING MARRIED. How on Earth could my step-son do this to me?? You knew I never liked her, now she's going to officially steal you from me! Not if I can help it.
step-Mom's been saving this potion for a long time now, and now is the perfect time to see if it works. Sure, you might still end up going through with the wedding. But I am going to swap our bodies so I can be closer to you than ever before. Her hot body could never replace a step-Mother's love.
