This is kind of in response to the mom who wrote Nudist Family.
Regarding the Nudist mom who would like to watch her daughter masturbate...
I am a single mom of a 15 year old daughter and I too would love to see my daughter masturbate. We have always been comfortable around each other naked and so I have had plenty of glimpses of her young body. I think back when I was that age and how I must have looked. I would love to be able to watch her and have thought about bringing up the subject of us doing it together but I've never had the nerve to go through with it.
Until recently I didn't even know for sure if she masturbated or not, although I was certainly quite active by age 15. I happen to walk in her room a couple of months ago unannounced and quite by accident. I found her completely naked on her bed humping a pillow. She was so embarrassed and I quickly shut the door and excused myself. Later we talked briefly and I just reassured her that it is perfectly normal, and apologized for not knocking. I could tell she was still quite embarrassed and all she said was, 'well now you know'. I even went so far as to share with her that I still masturbate for relief and that it is a lifelong need.
She did ask me if I did it as a teen and I said yes, quite a bit actually. I kind of hinted and said 'why are you worried you're doing it too much'? She said 'geez mom that's embarrassing'. I told her we could talk about it if she wanted and that I'm not judging her I just want her to feel comfortable to talk to me about anything. We had a brief talk and both did a little sharing. She finally hinted that she does it a few times a week.
Based on our talk I dont think she would ever be open to the idea, but having briefly seen her the way I did has given me plenty of good fantasy material when I masturbate.
