How can mom get their sons to be naked in front of her friends and her daughter friends?

It really depends on how old her son is,if he is a 6-10 year old it's very easy!,put a hidden camera in his bathroom and just tell him to change his clothes or take a shower but make sure the water is all drained before he takes a shower or bath and that you have the key to the bathroom,and by that your son will be naked in front of you and dont forget to take a pic!!
