Single Photo Edit

Hi I have some photo's from a dinner recently and my lipstick has come off leaving only traces on my lip line! I have no photo editing programmes and need someone to basically just fill in my lips as though I had just applied it freshly on.. This should not take long as I don't require any other sort of retouching or editing to the rest of the photo. It was take with a Cannon SLR D1000 camera so if you could help it would be great!
