Teaching my Sister

I had always had a very open relationship with my sister, she was three years younger than me and would come to me for advice or help about sex or dating. When she was 16 I began to notice that she was turning out to be quite hot, she has long brown hair, big round boobs and sexy tan legs. Boys flocked around her all the time; but she turned most of them down. 

One day she was in my room sitting on my bed talking to me about some guys who tried to pay her to give them a blowjob. She was wearing a tight black t-shirt which you could practically see her nipples from, and short gray shorts.

“So, I actually considered it for a second” she continued “it sounded kind of, ya’ know sexy, but I didn’t really know what to do.”

“What do you mean?”

“Well, I don’t know how to give head, besides I don’t think I’m gonna suck on some random guy.”

I laughed a little, “Well was the guy cute?”

She looked a little embarrassed “Sort of, I don’t want people to think I’m a slut though.”

I pointed out the way she was dressed as a sign of teeny bopperness, she was a little annoyed and gave me a light punch in the arm, I grabbed her arm and pulled it behind her back, we wrestled like this pretty often, as I pulled her in her ass touched my hip area and I started getting a hard on. She felt it and giggled a little, “What?” I asked, “Nothing… Hey, try that pulling my arm back thing again…” I did so and this time she put her ass on my hips and rubbed up and down against my cock a little. Then I let her go and she turned around.

“Hey, can you show me how to give head?” she asked.

“What? What do you mean?”

“Like, let me try it on you, just for practice and stuff.”

I thought it over, she was my sister, but I was also pretty horny and the thought was pretty arousing, so I got off the bed and standing up, I dropped my pants and boxers. She was a bit surprised by my cock; she sat there looking at it for a few seconds. So I took advantage of my situation and began instructing her.

“Come on, alright now get on your knees and try sucking on it.” 

She got up and then settling down on her knees she hesitated for a second, then putting it in her mouth she began moving up and down my shaft. She looked up at me, I put my hand on her head and pressed it down. After about 30 seconds she took it out of her mouth, “Now’ I said “ rub and lick it.” My sister caressed and licked my head , she then started massaging my balls, then I felt a huge surge go through my body and my cum sprayed out onto her face. 

“Good job” I said. She laughed a little, I lay down on the bed, she wiped the mess off of her face. “Try tasting some” I said, she took a bit and licked it off her finger, “Salty, but pretty good!”

But I was still horny, and she apparently was too because then she took off her shirt and bra, I was surprised by the size of her tits, they were a fully developed set, I had had sex with older girls that were smaller. She pulled my pants off and crawled over my legs up to my cock. Then she rubbed against me, she moaned I could see the light gray material of her shorts getting damp and wet. Then she pulled them off entirely and it turned out she wasn’t wearing any panties.

“dirty girl” I said. She smiled and then got off the bed and started walking away, she made a finger motion for me to follow, then we went into the bathroom, she started the water in the tub and as it began to fill up she bent over and held onto the side of the tub. I knew what she wanted and getting up behind her I put by cock into her pussy.

It was so soft and tight, it grabbed at my cock as wet juices leaked from it, my sister moaned as I slid into her. Then I began pounding into her beating my heavy balls against her ass. She moaned loudly enough for the neighbors to hear and started gasping for air. I kept on fucking her though. “Yes!” She screamed, urging me on as the loud roar of water from the tub continued. Then I felt another bigger surge in my body and I took my dick out to have my cum spray on her ass.

We were both out of breath and sweaty, the tub was full by now and we both got in. 

“God, that was good” she said. “Yeah, I haven’t fucked like that for a while” I said as I relaxed into the warm water.

A few minutes passed, we talked a little and caught our breath.

“Wanna go at it again now?” she asked. Then, not giving me much of a choice, she got up and sat on the edge of the tub. Then she spread her legs and I moved over and put my head near her pussy. I began licking her clit and the outside of her hole, she moaned and more wetness began to dribble down from her. Then I put my finger up her hole and moved it back and forth simultaneously rubbing and licking her, until she had her orgasm. 

I though she would be tired by now, but she said “One last thing… can you try putting it up my ass?” I was surprised, I had never tried anal sex before, the thought was a turn on and doing it with my sister made it even better. So I got out of the tub and so did she, then she got down on all fours on the floor and I got down on my knees. I pulled her butt cheeks aside and looked at the hole, it was tighter and smaller than a pussy, I spread it a little and she looked back to see what I was doing, then I slid my cock in.

At first she screamed, almost painfully, I began to go slowly back and forth. “Oh God! Its too big! Take it out!” she yelled, but I told her to relax, she did and I began to go faster, she moaned more and I went faster and harder. Her arms dropped and her head was on the ground moving back and forth as I fucked her. Then I took my cock out, she turned over and sucked on my cock until I cummed again on her face and in her hair.

We sat together for a little while, “Was it good for you?” I asked. “Well it hurt a little but I liked it.” She gave me a kiss on the cheek and got up to clean up and get her clothes.
