I'm gonna stay home this weekend with Michelle

One day, I was Vacuuming the hall way for the wife. She always set some chores for me and Michelle when we're not out. She feels it's right to do.

But when I finished and turned off the vacuum, I heard something. It sounded like Michelle and she was in pain. I went over to the door to her room. It's was half opened so I peeked inside. What I saw took me by surprise. It was Michelle on her bed, naked and fingering her pussy. Her eyes were closed and was moaning hard from pleasuring herself. Her juices were pouring out of her pussy.

I didn't know why she was doing this. I also wondered if she was gonna do this then why didn't she close the door all the way. I was wondering if she wanted me to catch her do it. But at that point I was getting real horny and wondered what I should do.
