Okay so I did my girlfriends sister once before I did her and their vaginas were like the same. I have a friend with twin sisters and their vaginas are basically the same. Finally I played a truth or dare game as a kid with sisters who were 2 years apart and they had the same kind of vagina too. I mean can one sister be an innie and the other be an outie? Or are sisters genetically set up to have similar vaginas.
