Oh yes - love that too. Love to make 'pillow' bodies of my old lady 'loves' - love to imagine tyhey are there in their undies as I 'hump'. and it is even better if you have a pic of them beside you to look at as well.
you should print out her face and put that on top. would give a very personal look and sense of her being there toether with her smell from the used underwear!
