Since the "ice" had been broken with my little sister, when we would get home from school in the afternoons, we knew that we had about 3 hours before our parents would be home from work.  She would often strip naked in her bedroom, with the door open.  When I would notice her, she would run around the house naked, teasing me to catch her.  

At my best friend's house, a couple of days earlier, I was helping my buddy clean out their basement.  I had seen a huge black dildo in some boxes that they were throwing out, and I knew instantly that I wanted it...and my friend never saw it. (apparently, his mom was hiding it in the trash boxes???)  Pretending to throw the boxes away, I slipped the very large dong into my backpack.

I was thrilled to get it home and inspect it.  First off, it was used, and it smelled very sweet of pussy juice.  Mental note*, friend's mom has a sweet pussy that likes big toys......  anyhow, so I washed it very thoroughly.  It had a big suction cup base which was nice to hold on to.  It was probably 12" long, and 2-1/2 to 2-3/4" in diameter.  HUGE.  Next, I hid it in my bedroom in a place that only my sister and I knew about.  I knew that my friend's mom didn't mean for it to be gone, but I knew that she could get another one easier than I could!!

Back to the afterschool education... So after catching my nude little sister, I told her to go get on her bed, on her hands and knees, with her ass in the air and her legs spread.  (it was amazing to watch her obey my sex commands!! Ooohhh my!)  So I got the big dildo, lubed it up really good with baby oil (our new sex lube) and walked into her room with it.  "Oh my gosh, where did you get THAT???" I told her the story, and she put her face down onto her pillow while I gently worked the head of the enormous cock around her pussy hole.  I fingered her gently, and kept up the pressure with the big cock until it finally slipped in.  "Ooohh yesssss!!" she squirmed.  "Be gentle, but go deeper!"  I watched the monster cock as it pulled and stretched her cunt hole skin with every stroke in and out.  As I would pull it out, her labia would stretch out, wrapped around the big cock, and inch or so.  Then I would push it back in, and the skin folds would go in with it.  It was mesmerizing to watch.  "Push it all the way in and leave it there, and lick my asshole until I cum..." was her next command.  I was more than happy to oblige!!!

As I got my face to her asshole and stuck my tongue on it, she pushed harder on the dildo with her hands, impaling her cunt with it.  I licked and tongued her ass for only a few minutes when I felt her body start to shake and tremble.  We were all alone, and she let it out!  Screaming and squealing, shaking, and flailing about, she rocked that orgasm for what seemed like forever.

"Suck it clean.  I want to watch you suck it clean from me.  Suck my pussy juice off that dildo."  Her pussy juice was sweet as honey.  I licked and sucked it off of the big cock toy until it was clean.  I loved it when she was "bossy" in our sex-episodes.  "Have you ever really licked a penis?" she asked.  "Of course not!" I said.  "We're not that way - my friends and I." I answered her thoughts.  "What if you didn't know them? Would you suck on a penis if you didn't know them?  Like in the porn movies?" she queried.  "Who knows?" I said. "Well someday, I want to watch that!" she squealed.  "Boys cum you know.? Right?  You do know that?" I replied back to her.  "I'm not stupid! I know that. The white, sticky, gooey stuff! I want to watch you suck it out of a cock like in the porn movies!" she smiled at me.  "I'll do that the day that you french-kiss me and make-out with me like I'm your lover." I said, matter-of-fact-ly.  (my sister is gorgeous!!!  : )
