Is It Normal For A Boy To See His Mom Nude? Part 2

This is the 2nd part of my confession. Please read my earlier confession to know the beginning.

After all the incident occurred, I decided to talk to mom as I was really feeling guilty about it. I explained to her about the incident for the last few nights. She was sorry for it as she doesn't remember anything because of her deep sleep. Also, she mentioned that as she has the habit of carelessly sleeping with my dad, she just got into the habit of deep sleep. And as he is away now for work issues, mom is just insecure about the new place and asked me to sleep with her.
When I asked her, why she didn't wear panties while sleeping then she told that its uncomfortable for her to sleep with inners(and its totally understandable due to the summer season)
Later she reassured me that it's completely normal for children to see their mom nude and there is nothing wrong with it. Also, she jokingly said that she knows the details of every part of mine as she grew up since childhood.

Lastly, she said that if I see her in that semi-nude condition again at night then I can cover her by pulling her clothes back.

The only thing I hide from her(to not make the situation awkward) is the fact that my dick rises the moment I see her in that condition. Although erection is normal in that situation still I dont wanna mention it to her.

One thing I realized after the conversation is that the feeling of guilt is gone as mom reassured me about this. And most importantly I dont have any sexual thoughts for my mom and am happy with it.
