both are very nice. fingers sliding in and out of hole and across clit will definitely get me off, esp if he knows the clit and focuses on it. But, with that said, cumming with a dick inside me is the number one preference. If that does work, fingers or mouth....
My man does amazing things with his fingers in ways his dick can't vice versa... so it's a win win situation for me
I wonder if you mean fingers being inserted to the vagina or fingers rubbing the clitoris or both. I have to say that fingering is quite nice and makes me come quite hard. A penis in my vagina is an altogether different sensation, but also absolutely amazing. I would have to say that coming with a dick thrusting in and out of my vagina is almost an out of body experience it is so pleasurable.
