By the time I was 14, my best friend and I were jerking off together a couple times a day. One day in the summer I went over at about 9 AM to see if he wanted to go find somewhere to stroke it together. When his mom answered the door, I was surprised to be told that he and his dad had gone camping for the week. I couldn't help notice that his mom was in a night shirt and her nipples were hard. She was plain looking, and a bit fat but I'd often told my friend I'd love to play with his mom's tits. She asked me to come in; that there was something she wanted to talk to me about. I sat down at the kitchen table while she reached into a drawer. To my surprise she threw out my buddy's collection of porn magazines we jerk off to. She asked me if I knew about them. I said that we had found them. She said she knew what we were doing with them as the pages were cum stained.
So here I was being confronted by my best friend's mom, her nipples staring at me and she looked mad. She was yelling that we could hurt ourselves. She said I would either have to go to my doctor or have my own mom check my penis for injuries. She went to the phone to call my mom and I begged her not to. She said I would have to show my doctor. Suddenly she noticed I was rock hard. She screamed at me. HOW CAN YOU STAND HERE INFRONT OF ME WITH YOUR PENIS LIKE THAT! I just had on gym shorts and a precum stain was showing already.
Again she screamed at me and called me a pervert. But she then said that she might as well check it for me, but cautioned me not to think sexually as she did.
Well by this time I wasn't sure I could even pull it out without cumming. She made me stand in front of her and turn side to side, lift it up to see my balls. Then she told me to stroke it. As soon as I touched it I exploded all over her tits and face. She started to laugh. She said I guess it's working ok. I turned beat red. She told me not to tell anyone. This went on the whole time my friend was away and I slept over 3 nights as well.
Later on that month my friend got the same treatment from both of us, but that's another story.
