My stocking fetish idea would be that in a scene where the girl wears nice sheer stockings, like Ria Sunn in SZ2956 for example, towards the end of the scene the guys could take her stockings off and put it on their dicks and get a blowjob like that, or fuck the girl while "wearing" the stockings on the dick, and maybe cum inside, the girls could lick it off, or put on back the cummed stockings maybe. Some illustrations in the pictures below.
What do you think?
