Ok check this out. I was fingering my girlfriend today while she was sucking me off, when i reach the very top of her vagina. I noticed a little round thing that seemed to be attached to the top of the wall..as if it were meant to be there. I felt around it and noticed it had a little hole. I asked my girlfriend about it and she thinks its her Cervix, or the beginning of the umbilical cord for when she gets pregnant.
She was sitting with her legs open toward me, and i had my fingers in there all the way. Like i said, its at the VERY top, and its round and seemes like it supposed to be there, and it has a small hole. What is this thing?!
