This is why I'm always prepared ahead of time. It's not like I don't know it'll be shooting out of my penis like an erupting volcano, causing a real mess as you put it your comments.
I used to do this for my sister in law, she was on the opposite end of the age scale. When we would watch TV together, I would start tugging at my shorts with my cock hard. She knew what I was about to do. I would work my cock out of my shorts and start to stroke it. She enjoyed watching me while I stroked and cum. We would be sitting next to one another on the couch. I loved doing that.
There are 3 or 4 of this guy doing this while she sits close by.I think she's his mother in law.I wonder about her eye sight.Maybe she can't see clearly.He should be prepared with something to clean up with.He's got cum all over his hand and driipping down his cock
