This happened on Monday morning. We have a friend staying with us on the weekends. After everybody left for work, she and I were the only ones in the house. She has been sleeping late in the mornings so I wasn't worried about her walking in on me. I thought I had plenty of time as I sat at the kitchen table. I had removed my rope and was sitting there nude stroking my cock.
She woke up earlier than I expected and walked into the kitchen, there I sat pumping away. She took one look and said 'Oh My' with a big smile on her face, walked into the room reaching down and stroked my dick a couple of times then poured a cup of coffee and sat down.
As we talked I could see how excited she was getting moving around in her chair. I said that there is a vibrating wand in the bedroom if she wanted to use it. We got up and went to the bedroom then she asked if I had a tape she could be watching. I slipped in a hot one, turned it on, and started to leave so she could have some privacy. Then I thought, why not stay and join in on the fun? we were laying on the bed side by side watching each other. Her with the vibrator on her clit and a finger deep in her bare pussy at the same time. Me stroking my cock and pulling on my nipples with the other hand trying not to get too carried away and cum too soon.
After about an hour, she started moaning and shaking, then I could hold back no longer and started shooting cum all over my chest. After laughing and relaxing a few minutes we cleaned ourselves up and started our day. What a great way to start off the week, I can't wait until this Monday to see what kind of week this will be.
