One thing I can say for S, is that he always appreciated my underthings. He always admired my lingerie, he liked lacy things, he liked sheer things.
He would get this look on his face when he saw me dressed up. When I dressed in lingerie for him, he would be more tender with me, he would take his time.
He liked all my underwear, and claimed he could guess which one I wore just by touching them - he would feel the texture and shape and know exactly which one I was wearing. He paid attention, he even noticed when I wore something new.
And although I mostly wore thongs everyday, he would be a little disappointed on the rare days I wore "full back" underwear. Unless it was sheer.
J on the other hand, he hasn't really ever commented on my under things. Not that I've worn the big guns for him, but I've worn some lacy, sheer things for him. Not a word from him. Oh well. I guess he does put my underwear away carefully once he's taken them off. 8:16 PM
