My sister used to sleep in my bed, and we used to touch ourselves

I'm a 28M and my sister is 23F. So back in the day we used to have our parents buy us into those funhouses at the mall, you know the kind made of playballs? I remember one time my sister and i were about 5 and 3 respectively, and we got scared since we couldnt see each other, and we thought we lost each other. so we both screamed each others names and found each other, and since we couldnt see each other, we started holding each other by the waist, and we were just floating in the sea of playballs holding each other tight for comfort. I dont remember what happened next, but my sister remembers and she told me that when we got home, she used to ask mom if she could sleep with me, and mom said it was fine. so i'm guessing it went on for a couple of days. <br> Fast forward a few more years, to when we were around 10 and 8 years old, we used to sleep together again in my bed, and this time, i remember that we used to touch each others privates, i used to put my finger in her pussy, and she used to jack me off for a bit, sometimes i'd rub my dick on her pussy, but we never actually had sex. I dont know how we stopped, or why we even stopped, but we just did. back then i had no clue that i was doing anything wrong, and it felt like the most natural thing to do, i used to feel very comfortable with her, and we could talk about anything. <br><br>It's only later on that i found out what we were doing was wrong, it was very confusing for me, but in a way i'm glad that it happened, because we became so close, and we still are. I dont know if she remembers all this, and i surely dont want to bring it up, i dont know what she'll think, but it was definitely fun, and i'll miss it for the rest of my life.
