By the time I was 14, my little sister was 11, and she was already a sex pro with the dildo collection that our parents had.  We had progressed from fondling to everything but fucking.

We came home from school one hot summer day, all alone, as usual.  After a little while, I didn't see her, and knew that she must be in her bedroom.  She was always happy to see me, when I peeked in on her.  The big dildo she was using was sloppy wet, making the sucking sounds that it did as it penetrated her tight little cunt.  I smiled and said, "I'd be happy to run that for you!"  With a cute smile, she obliged, and rolled onto her stomach and spread her legs as wide as she could.  After a bit, I could tell that she was feeling really good, and she wanted to lift her ass in the air, and get on her knees.  That gave me really good access, putting her hot little wet cunt right in my face!  The slurping and sucking sound that dildo was making, got me hard as a rock instantly.  I said to her, "hold on, I've got something good for you!" and I got off the bed and undressed.  My cock was huge, and ready for her.  

Wanting to enjoy the moment,  I put just the tip of my penis into her vagina.  She started to buck and push against it, trying to drive it home, but I wanted to slide it into her just an inch at a time until I was balls-deep home into her dripping pussy.  Finally, she won, and begged me to fuck her really hard and fast!  I felt like a machine, like a piston, at home in its cylinder, lubed up, and running a thousand rpms.  We fucked and fucked, and then fucked some more!  I fucked her in the scissors position, doggy-style, missionary.  

Neither one of us knew much about birth-control at that point in our lives, but we had seen so many porn movies where the woman gets a facial, or cum on her tits, or a creampie, occasionally.  I was going to ask her where she wanted me to cum, and I think, reading my mind, she said, "cum inside me!"  "What?" "You heard me.  Cum in my pussy, like they do in the movies, where it runs out afterward! I want to feel hot cum in my pussy!"  I told her I would think about it, and rolled her back onto her knees, with her ass in the air.  The sight of that beautiful, bald, gaping pussy was incredible.  My cock went straight in, and we went back to fucking hard and fast. I was just about to cum, and told her to get on top of me.  Her budding little nipples now had some breast to them, and seeing her tits, with her pussy impaled on my cock was too much to resist any longer, and I told her that I was going to cum, and to push down with her cunt as hard as she could, if she wanted a cum-load deep inside her loins.  

She rode out my orgasm like a champ, and we didn't even move for a couple of minutes, my cock pulsating inside her.  She broke the silence by saying, "Will you lick my pussy clean? That would feel really good right now....?"  I didn't really know if that was taboo or not, and I wanted to please her, too, so I said, "Sure!" She moved toward my face, still on top of me, and I slid down underneath her until my nose was at her clit, and my tongue at her steaming hot hole, that was now dripping hot cum into my mouth.  She loved my nose on her clit, and began working it, rubbing herself off on my face.  My tongue licked and sucked her cunt hole, which leaked cum the whole time.  After probably ten minutes, she was done, and collapsed, exhausted, on the bed.  I chuckled at the sight of her, and went to take a hot shower.  She went to bed early that night, taking a dildo with her, to reminise about the afternoon.
