Pinkie Promise

You (Stephen) and Debby have been friends since you were born. When you were 3 you played doctor and discovered the difference between boys and girls. It was then that you made a pinkie promise to share any more differences that developed over time. It seemed sensible at the time you had seen your mummies and daddies were different to you. With time and when you started going to school it seemed silly.

However, for some reason or other, you found each other sharing each lost tooth, new tooth, and growth spurt. It got weird when you went through puberty. Your first public hair, her first period. She flashed you her boobs when she reached A cups. Then B cups, by DD it was weird she would make some excuse to come over and show you her newly resized breasts. You also found completed to show her your penis when it grew. She even showed you how her vulva had been developing. At some point you found yourself dating. It was just easier to show each other your bodies if you were dating. Despite this, the furthest you went was doing oral and hand jobs that went both ways.
