My aunt and I are the same age, were in the same grade, and went to school together. We lived close by so that my mom and grandma could drop one of us off and have a babysitter down the street. We spent a lot of time with each other because we each didn’t have any siblings or cousins close to our age.
Middle school comes around and our hormones start kicking in. We practiced kissing each other. That led us to sneak around to make out with each other. We spent so much time together and no one gave it a second thought because we were always hanging out with each other. Eventually we started groping each other and figuring out how our bodies worked together. It never got to the point of s** although there was a time it almost happened. She started to feel guilty about it and we had to stop doing this s*** with each other.
To this day we have never talked about it, never acknowledged it. In high school we started to grow apart. We got dared to kiss each other at a party with 7-minutes-in-heaven and she got so embarrassed that she ran out crying (we did not kiss, we were just pressured to by a****** kids).
Our family never found out and I don’t think either of us told anyone for fear of embarrassment.
