I would like to begin by saying I love this site, and after the experience, showed it to my mom and she loves it too!
Well I live alone with my mom since I was five. She just turned 39 and is in my mind great for her age. We have always been close, so it wasn't that big a deal when the incident happened.
I thought I was alone one afternoon while my mom went to the gym as she always does Saturday afternoons. I wanted to try something different that would really get me off. So I put on one of my moms many porno videos she has hidden on the tv in her bedroom, and got the idea that I would try wearing some of her sexy thongs and bras while jerking off, since I knew she would not be home for a couple of hours. I had the volume turned up to get into the mood, danced around a bit feeling myself in her panties. I guess I got so wrapped up in the moment, moaning and jerking hard lying on her bed, that I did not hear her come back early.
I heard her suddenly clear her throat, and asked just what I thought I was doing? I was like a deer in headlights! Shockingly she smiled and said that she enjoyed that video a lot and it works well for her. She told me to enjoy and finish up and she had something for us to do afterwards and smiled. She had turned to leave, so I just kept going since I was so turned on still. All it took was a few minutes and I cummed so hard.
After I came downstairs to the kitchen, she was waiting, smiled and said she hoped she didn't ruin it and smiled. She said lets go to the mall, she wanted to buy me my own set of panties and bra so I wasn't using hers!
We looked around the store, buying a few pairs herself. She was excited to get back home. When we got home she said let's have some fun, go try them on for me and she wanted to see how they fit me and she was the same.
We ended up having some fun with the whole thing dancing around in her bedroom to some dance music, even grinding each other. We put on another video got out her dildo (life-like) and told me to get going. We watched each other get off, I ended up cummimg on her tits! wow, it was a blast.
I am glad she was cool with it. We still do it with each other time to time. I hope she reads this.
