Have you ever had those painstakingly dirty thoughts whilst masturbating or cumming. They are so naughty that you are almost ashamed? You try put them to the back of your mind but every single time you reach the point of climax, those same dirty desires pop into your head.  Your Mom has been fighting these desires too long, she pushes them away and they come back stronger. Now she cant even have a conversation with you without imagining touching you, or feeling you. In a way which Mom and Son should not. The desires are so strong, she is starting to act differently. She is wearing lingerie around the house, she is suggesting you both spend alot of time together when normally she is always stressed with work. Your Mom has given in and she is giving up fighting whatever little voice or conscious inside her. She wants you. When she comes clean and tells you what has been happening, you try to find a solution. Perhaps mutual masturbation would work? No it only intensifies her desires. She says she will go and get help, but now she has awakened something in you. I suppose, it just depends who can show restraint and who will give in to their desires first.
