I am so old and still I keep learning new stuff.  Last week I had some quality time with a girl who was a true 10/10.  

After we had played for a bunch, I rolled her on her back, raised her leg, rested my head on the inside of her thigh and began (again) playing with her vagina.  This time I slipped my thumb in and pressed upward.  I kept my fingers out on top but pressing down.  With in a few seconds, she blurted out, "oh my god, you found my g-spot."  With in a few minutes she had her third orgasm of the night.  After she came, she pulled my head up to her level, said, "I just have to kiss you," and put her tongue down my throat.  Using my hand like that was totally instinctual.  I had never done it that way before.  The reaction was amazing.

Has any one else discovered that technique???
