I was never punished for masturbating but I did have an interesting experience. When I was about 11 not too long after I started menstruating I started to use my mothers vibrator fairly frequently. One day She walked in on me using it in her bathroom shower, I hadn't turned the water on so you couldn't miss it.
Later in the day we had a conversation. She was matter-of-fact about the whole thing. The only thing that bothered her was she wasn't into sharing her sex toys. She was very fastidious and always put fresh condom on the vibrator every time before she used it. Catching me in the shower was really an accident but she had suspected I was using the vibrator for a while she noticed the condom supply was going down faster and then she noticed the knot was tighter than the condom was looser on the dildo then when she put it on, she really stretched it a lot more than I did when I put a fresh condom on it and put it back in her bedside drawer.
She bought a gross i.e. 144 Ramses condoms just for use with her dildo. We ended up looking at a couple of sex toy catalogs together and I picked out a straight vibrator/dildo more or less just like hers but smaller in diameter. I also wanted a rabbit type as well. She went into New York the next day and came home with the vibrator/dildo I wanted and also a rabbit.
A couple of days later she dragged me to our local pharmacy. It was kind of an old-fashioned place, a holdover from the days in Connecticut where all contraceptives were behind the counter thing. My mom knew the woman that worked there but primarily handled rubber goods and contraceptives. I swear we spent while more than an hour in there with my mom in the saleslady looking at different brands of diaphragms and spermicides. My mom ended up buying a new diaphragm and a couple of tubes of spermicide along with condoms for me to use with my new dildo.
It was my first time that my mom bought contraceptives at the drugstore when it I was with her. We had bought menstrual sanitary supplies like napkins and tampons together but never contraceptives. I do recall a couple of times when we would go to the drugstore and she would get everything we needed, get back to the car and say she "forgot something". Invariably she would come back with a couple of tubes of Koromex or Ortho vaginal cream. At the time that seem kind of odd to me that she would not buy it in with me present. Perhaps she didn't want to be embarrassed buying it or maybe didn't want me to be embarrassed.
When we are home she made no attempt whatsoever to hide what she bought and often would ask my sister or my self to carry it upstairs and put it away in the bathroom.
