Although you wouldn't think so, months went by with my sister and I playing with the dildo, and me performing oral sex on her, almost on a daily basis. 

I could notice her tits getting bigger, as we got older. She grew bolder all the time, requesting what she wanted of me! I learned her body intimately, and knew her habit, wants, and desires well. Some days she just wanted me to lick her clit, or finger her butthole, or even fist her pussy.

"I never get to make you cum!" she said.  "Why not?"  "I don't know." I said.  "Come here," she said, and she went into the bathroom.  Went I went in, she was naked, and sitting on the edge of the counter of the sink.  Her perfect pussy was exactly at the right height for my cock to rub on it.  She had turned out the light, but the door was open, and I could see her bald pussy in the light that shone in through the doorway.  

"Rub it on me!" she pleaded.  I was already so hard that I thought my penis might break off if the angle was wrong. As I began to stroke her slit with my cock, she was already deep in space, her eyes closed, her head back, and her little tiny nipples budding out at me, which I would suck on occasionally.  From the bottom, I would slide my cock up from her soaking wet hole, up through her slit, and across her clitoris.  She was loving it and in another world.  Soft moans escaped her breath. I could feel her cunt hole sucking the head of my cock ever closer to penetrating her with each stroke. Soon I got lost in my own little world of pleasure, and just kept going and going.  

I lost track of time until I realized something, which suddenly jolted me back into utter awareness - I was starting to cum.  "I, uhhh..." I stammered.  "Oh my."  I realized that my cock was prisoner to her loins.  Her pussy had a grip on me that was holding on like the linebacker who just caught an interception. "You don't want me to..." I couldn't think very fast in my hazy mental state. I was deep in her cunt with my throbbing cock, it was starting to spray her depths with what was going to be an absurd amount of cum.  As I was pulling out, I felt the first spurt let loose inside of her pussy. The next gush came just inside her, and the next few, right on her clit. 

I just stood there in awe, watching cum spurt out of my cock onto her bald cunt, covering her clit. I let my cock rest on her hairless mound as the last sticky globs stuck to her pussy lips. As she was leaned well back, the thinner cum ran back down into her open vagina. But I could see that her pussy was a huge mess on the outside. Now my throbbing cock was hanging down as she surveyed what I had done to her.

"Please lick my clit!" she said.  "I'm so horny looking at your cum!" "Lick me and then kiss me!" she plead with me. 

I had seen hundreds of porn movies in our parents room, in their collection, as had my little sister.  We had both watched huge cocks cumming in hot little porn stars, cute girls with cum in their pussies, cum on their tits, cum in their mouths;  over and over we watched them. I knew it wasn't going to hurt me any to taste it, feel it on my tongue and in my mouth, and to swallow it.  

As I looked at my cute little sister, sitting there with a huge creampie, and all of her glory hanging out everywhere for me, I got down on my knees and started licking the cum from her hot little body. It was thick and hot, and I didn't know exactly how to do it, so I sucked it into my mouth as if through a straw, then licked her clit and labia until she was clean on the outside. The salty taste was fine, and the thick globs stayed on the back of my tongue. My sister then spread over my face by putting one foot on the toilet and her other knee still on the sink counter.  I put my mouth over her cunt hole opening, and the cum poured out of her and into my mouth.  I had to swallow so many times that I lost count. To finish her off, I licked her clit until she came, and she was completely satisfied. I held her briefly, and we french-kissed for a few minutes, and her eyes twinkled when she said that she could taste my cum, and that it was really good! I knew there was going to be more.
