Oops. It was super thoughtful of your stepmother Mandy Rhea to cook your favorite dinner when it was just the two of you, and the scene starts with her giving you a taste of your favorite dish. She knows that you like it super spicy, which is what this scene becomes when she accidentally spills some of it on you! You just want to slip away and change your clothes, but your stepmother insist on taking care of everything herself... and when she finds that bulge in your shorts, she insists on taking care of that, too!
