first tell her to wear looser pants. because wearing tight pants will not do anything. so you unbutton, and slowly work your way down, rubbing the outside and such. though most guys have no idea where to rub, and the girl is just faking it the whole time, but then you use your middle finger and go in slowly, then go in and out a couple times, and then as your finger is inside of her, move it up and down. nooo, not in and out, up and down, and it will feel like a sponge sort of. that would be her g spot. and go slow, and then get fast, she will like it. seriously. i am a girl, i know what i like.
