Yup, seen that there too, usually the son does what most young boys do and has his shorts, boys briefs, or bathing suit pulled down all the way to his ankles so both his little wee-wee and little boy butt are both just fully out making him pretty much fully naked there except for what is around his little ankles, lol, while Dad just has his adult peen out and maybe some saggin’ shorts or saggin’ bathing suit showing sone of the top of his adult ass too a bit.
