Possibly, but how would a friend know? I’m making an assumption that it would have to be an adult to make the discovery and then make it’s way down to the kids. Not impossible for that to happen, but it’s probably as likely that the son would never find out. Or not find out until he’s an adult and maybe the discussion is had at that time. While it’s not impossible for other kids to get access to this, it’s less likely than if this was a situation where Mom has an only fans or does porn or something that can be accessed on the Internet.
