I like to my wife when I see her wearing my stepdaughter's panties

I already feel an unusual lust for my wife, even because even though she is mature, she is still a true spectacle of a woman and I end up feeling hornier and wanting to eat her more when I see her wearing my stepdaughter's thong panties. Seeing her like this makes me feel even more like putting my dick in this greasy pussy of hers and in this greedy and warm ass she has.
