I went back to my daughters house about a week later. I was actually thinking of not going, but my thoughts of her were too strong. When I got there she was wearing tight little jeans and a short half shirt. She asked me if I was in the mood to build something, It's not what I had in mind, but I told her sure. She told me she wanted a small stool that she could mount her dildo on so when she needed a good fuck, she could take care of business herself.
I built her one in about 45 minutes and made it look like a sitting stool, just in case her husband asked what it was. I told her I would finish it so she could use it in her bedroom as a new vanity chair. (Minus the dildo).
I brought it up to her room to make sure it fit under the vanity. Perfect!
When she came into the room she smiled and said, "that looks perfect, I guess I should try it to make sure it works."
She walked over to her drawer, pulled out her dildo, licked the bottom and stuck it to the seat. After nodding her head in approval, she unzipped her pants and wiggled out of her jeans. She was standing there in her little tight panties and a half shirt. She straddled the stool, pulled her panties to the side and gently sat down. All I heard was, "Mmmmm." She was facing the vanity and was looking right at me through the mirror.
I asked her how it was working and she said, "perfect, now when I'm horny, I can ride this and think of my daddy." I told her I was glad I could help. She must have had a new spot for her toys because she reached into the drawer of the vanity and pulled out her vibrator. She put it on her clit and just enjoyed herself while I watched. She turned to me and with a smile said, "I hope this bench is waterproof." Then about 10 seconds later, she came.
