Is it normal that young sisters experimented as kids?
A girl I am dating confided in me that she used to experiment sexually with her younger sister. Her sister was around 6 and she was around 11. They shared the same bed and they would grind their vaginas against each other at night until they climaxed. Apparently this occurred somewhat regularly (although not every night) for a few years. The girl I am dating said that she was usually the one who would take the lead. This was many many years ago and she is an adult now. Is this very common among sisters at that age?
