Want to have my mom give me a handjob/blowjob

so i would start the conversation in the car asking if she can see this thing on my penis because its a concern. She would try to see it in my room or bathroom but i would say no because it needs to be hard. I cant show her it soft. Then i would allow her to touch it but idk what else to do. There is nothing wrong with my penis btw. I have pictures of her feet and everything and i constantly look. I dont think she knows but i dont know how to tell her. Any ideas? So the goal is for her to give me a handjob/blowjob or teach me about sex by doing it with her. I want to see her nude and want to taste her feet. Please give me as many suggestions and ideas please!
