for me, it is about that direct contact with those feet with nothing in the way, but occasionally i do like to have a well worn nylon and sometimes start out fj where I tear a hole in them and her toes with the nylon blanketing my dick help hold it in place, LOL
kinda freaky but imagine what a person looks like with a sheet over their head when trying to dress up as a ghost and you can picture how I like to have my dick look with a stretched nylon over it
