You probably had an experience like this way back in puberty. I know I had one, that's for sure. I was getting it on with my girlfriend in the bedroom and there wasn't anyone around. Everyone was out working, mom and dad too. I ain't had any brothers and sisters so this home was all safe. Though gramps lived here and he usually wasn't around home, but this one day the dude actually decided to visit without telling anyone, which obviously was a bad idea. However, I locked the doors before doing anything with my girl, so I got to put my clothes on and the old man didn't see my dong. However, some people don't lock their doors and shit like that. They don't think this shit through. And that's why they get caught fucking hard but their significant other while cheating, or by their unfortunate friends or family.
