But, no, I have no sisters, and I have not seen my mom naked.
It felt wierd at first but now I like it.
My mom was always free about walking around nude.
Personally i think there is nothing wrong with that he will get over it, he may display arrousals but would never touch her and thats the difference.
My family has always been kind of nudist or semi-nudist at home.
How is it ok for me to be stood in the same vicinity as what i have just mentioned? Walk in the room and see this.
