Cupcake Needs To Cum!!!

My best friend 'Cupcake' recently told me that she has never had an orgasm. When I heard this I was shocked, I tried telling her a few of the techniques on this site but she had either tried them or they wouldn't work when she did try. She's done everything from pillow humping to fingering, rubbing, using the bathtub etc. I just assumed that she gave up to quickly or she wasn't trying hard enough, but the other night she told me she was fingering herself I was talking to her the whole time and after 30 minutes she finally gave up and again stopped before she came. She really wants to have an orgasm but can't find the right way to so it. So if anybody here knows an uncommon masturbation technique that could possibly help please comment on this story. Thank you so much.
