It was a slow summer day and I decided to leave work early and surprise my wife Bonnie at home. Since it was summer she was out of school. The kids were off to a camp with the neighbor's kid so this would be a great time for a little afternoon fun. I drove into the garage and quietly slipped into the house. I had expected to catch her on the couch watching TV, but she wasn't. In fact, the TV was off and the house seemed empty.
As I continued to walk through the house I noticed that our bedroom door was partially closed and I thought I could hear some sort of sound. Standing outside the door I heard her moaning with pleasure. I had bought some vibrators to spice up our love making but she said she would not use them without me there. Maybe she had changed her mind. The anticipation was already causing my dick to harden. Whatever she was doing she sure sounded like she was enjoying it.
Wanting to surprise her I stripped out of my clothing and stepped closer. As I peered through the door I could see her on our bed, lying on her back. Her eyes were closed tight and her hands alternated from her large breast to somewhere beneath the covers. The lower half of her body was covered by a sheet but her knees were pointed up. I stood in amazement watching as she got herself off and I wasn't doing too bad myself either as I had begun to slowly stroke my dick.
