I was about 12 years old at the time. I lived in a small three-bedroom house with my divorced mother, and my older sister.
I got home from school late one afternoon after having played football with my friends. I was all hot and sweaty, so my mom insisted that I take a bath in our only bathroom, before dinner. I went upstairs and proceeded to take a bath. I had been sitting in the bath tub for about 15 minutes, when there was a quick knock on the door and my mom came walking in to use the bathroom. That was pretty normal for our family, especially in the mornings. I quickly covered myself with a wash cloth.
After she finished going to the bathroom and was getting ready to leave, she looked down at me and said, 'You can't get clean just sitting there, you have to use soap.'
With that, she got down on her knees, grabbed the wash cloth and soap, and asked, 'Do I have to show you how to take a bath?'
I was totally embarrassed. My cock was now completely exposed, but she didn't seem to notice. She had me turn around as she washed my neck and back. Scrubbing very hard to make her point.
'Okay, let me get the front,' she said. I reluctantly turned toward her as my cock was bobbing up and down in the water. She finished washing my neck and chest.
I'm thinking this bathing lesson is over when she says, 'Standup, I want to get your legs too.' I started to protest when she assured me she had seen me naked many times before. So, I stood up, facing her totally naked except for some soap suds.
She took the wash cloth, got it all soapy and then rubbed it up and down my legs. This felt so good. The next thing I knew, I had a raging hard-on in front of my mother! It was standing straight up. I could have poked her eye out. I just looked straight up at the ceiling trying not to notice.
She continued washing my legs each time moving higher up my thigh. And then, just like she must have done it when I was a baby, she began washing my cock and balls. All she said was, 'You have to get this clean too.' She let the wash cloth drop in the water and grabbed my cock with her soapy fingers. She proceeded to stroke my throbbing cock. My knees were shaking. I was ready to explode, as she stroked faster and faster. This went on for minutes.
I was just on the edge, when all of a sudden she stopped.
She looked up at me, smiled, and said, 'There, now you're clean. Dinner will be ready in ten minutes.' She got up off of her knees, dried her hands and left me standing there with my bulging cock dripping with soap.
There was never another bathing lesson. Now that I think about it, I shouldn't have been such a good student.
