Like Mommy And Daddy

I was very young when I began pleasuring myself. I would guess the age to be about 3 or 4. I have distinct memories of grinding on and humping my stuffed animal Tigger till I felt that familiar heat in my *****. Gradually as time passed I moved on to piling pillows and blankets under me. I would straddle them butt naked and just go to town.
I shared a room with my younger sister and I would always wait till she fell asleep. Then I would remove my pajamas and shove a pillow under neath my groin. Sometimes my I would get too into it and forget to keep my breathing quiet or not moan out loud. On this particular evening I was going at it quite hard and was shaking my bed pretty intensely. So intense that it woke up my sister. My heart stopped when I heard her voice ask what I was doing. I pulled my blanket up around my naked body, and told her to go back to sleep. My sister then turned on her lamp and asked if I was naked. I remember being bright red and telling her no I wasn't naked. My sister gave me a strange look and shut her lamp off and I assumed she went back to sleep. I waited for what felt like an hour till I began grinding again. I was still horny believe it or not.
The next evening my sister shut off her lamp and we were laying in the darkness. I heard her sit up and she asked me why I pretend to be mommy and daddy. I asked her what she meant by that, and she said that she saw mommy and daddy get naked and rub their privates too. Now I was completely mortified and embarrassed by this point. Then she asked me if it felt good to be naked and rub. I told her it did, it felt amazing. And then she asked me if I could teach her how.
Maybe there is something seriously wrong with me, I dont know, but for some reason this really turned me on. So I told my sister I would teach her how to grind on things like a mommy and a daddy.
I made her come to my bed and take off her bottoms. We sat facing each other in the darkness each straddling a pillow. I began gyrating my hips and squeezing the pillow tightly between my thighs. She watched me closely and carefully began doing the same. I remember she seemed to have trouble at first, not sure how to make it feel good. But after a few moments I could tell she got the hang of it. Her breathing got shakier and deeper and her finger nails dug into my sheets. And then she leaned forward, laying on her stomach, her young ***** humping my pillow.
Her little face was buried in my mattress as I heard her begin yelping softly. I humped harder my skin raw against the material, my eyes watching her little *** clench as she dug her pelvis into the pillow.
I came at the thought of being that pillow and my sister came quickly after too.
