I like the idea. This happened to me in high school except it was a boy girl thing. She had a huge oral fixation and loved having a penis in her mouth. The longer I could hold out the better she liked it. I had my license and a car and drove her home every day. She would go down on me before we left the school parking lot. We would go to her house to have sex nearly every day as her parents had full time jobs. One day however her mother came home early and made it into the house without us hearing her. I was sitting on the couch and her daughter was on her knees in front of me performing. I think her mother snuck in on purpose to see what was going on but I noticed her and was to scared to do anything, so I just sat there pretending not to see her. After about 4 or 5 seconds I realized she was not going to stop us. I donít know how long she watched but it must have been about 30 seconds before she left. I can tell you it was wild sitting there with mom watching her daughter suck me off and loving the dick in her mouth. After the mom left it took me about 30 seconds to get off with my hand fastned tight to the back of her head. I still remember that, on the second go around, if I could not get off she would start to remove her cloths for my viewing pleasure. First her shirt and bra, then her pants and undies.
We quit seeing each other shortly after that.
