I think that you girl friend should insist that not only you see her naked, but insist that you help her prepare for you ex step *******. Bath her, shave her. Make their meal. Clean up the dishes.What Kenneth have mentioned is correct i have not even seen her pussy and only time i even came close to it I spoiled my chance before i could even remove her bra.
When the time comes taste her before. Perhaps lay in the floor as they fuck on the bed. Taste her in between him cumming in her and clean up up after a night of fucking. All the while jerking off as much as you can. Perhaps even taking some viagra to help keep you hard for the entire time.
