The other day I got home from work early to find my mom doing the dishes. She looked at me and said 'Your home early', and I didn't answer. Then she said to go to her room in five minutes because she was having trouble with her computer and needed my help.
So I went up there and she was in the bathroom and said she would be out in a minute. So I sat on her bed and waited. We were the only ones home. She came out of the bathroom in a robe, nothing unusual, and shut her door, and said she had a serious question to ask me and that her computer was fine. I said, 'Ok go ahead', and she said 'Do you masturbate'. I wasn't sure what this was all about, but I figured there was no use in lying, so I said yes. She asked how often and I said about twice a day.
Then she said if I wanted, and was comfortable with it, she could show me a great way to do it. So I said I guess so. Then she said to get naked, I hesitated, but I did. I wasn't embarassed about my cock size, about seven and a half inches erect, (which it was), but more just about being naked in front of my mom. Then she took off the robe to show a sexy black bra, and matching thong, and said if I wanted she would take those off too. I just nodded and she did.
She also had a great body for her age. I had seen her naked before, once in some pictures my dad had taken, that were in his porn box, which I used a lot.(The porn in the box, not the pictures), and once on a video that my dad had shot, of her lying on the bed using a vibrator. She showed me how to hold my cock, and then said to try, which I did, I came faster than I ever have before, and my cum shot onto her bed, and a little on her leg. I apologised but she said not to worry, and she would clean it up. I thanked her and left, and we have never acknowledged this since.
