As a young boy my mom would fill the tub and I would get in and she would use a wash cloth and wash me all over. She would make comments like when you are older make sure you pay attention to these areas, which were behind the ears, back of the neck, crack between fanny and penis.
As I got older I would assume washing but she would come in at the last and make double sure I was clean in the areas she worried about. This lead to a stiff penis in her hands which drove me to ask the question 'why does it get hard' to which she replied 'its part of growing older' later the birds and bees story which went over my head about making seeds and female eggs.
Anyway, at 13 years I was taking my own shower and answering the question, am I clean all over? I was then having wet dreams but not yet masturbating. Again being told, part of growing older. A really bad flu season and I came down hard, doctor and pills, lots of liquid and rest. Chills and fever, damp PJs and mom says I have run the tub for you, get up, hop in, I will clean you.
The old method kicked in and behind my ears, neck, crack and penis got a good scrubbing. Only this time the penis got hard as before but a few seconds of cleaning with her hand caused spurt after spurt of cum. Oh she turned red, said oh I am so sorry, It felt great to me. anyway she never washed me again, no words were said, but I learned about masturbating soon after and no more wet dreams,
