When me and my sister were together, she would get on top of me, we were both clothed and grind. Kissing me and hugging me. I didn't know what we were doing, on top of my bed, but I was pretty damn scared. I remember knowing this should not be happening, but she would always comfort me and tell me it was ok. So as things progressed years later, things started happening at bed time. We would be put to sleep, me and her shared a room, my other sister had her own room. The first time it happened, we always did pretty innocent things never anything to crazy, but one night she got naked and came over to my bed and took off my clothes. We were both naked, I was really scared, at this time I was school aged. She would get on top of me and force me to open up my private area, expose my clitoris and she would do the same, she would rub them together. I didn't like this, I was not producing any wetness. I was pretty uncomfortable. I tried to make it stop but she persisted... her vagina obviously produced wetness and it started to rub on me, this made it very enjoyable. I knew it was wrong but it felt so good I didn't want to stop anymore! This went on sometimes every night for a long time. So wrong, but so right, as they say (((kek)))
