I never looked at my sister sexually until she turned about 13; when she started developing. This is a true story; I was 16, she was 14 at the time.
My parents weren't really the type of people that would go out much, but it was their 15th anniversary, so they decided to go out to dinner and a movie. My sister and I always fought, but we still got along. She was fun and easy to fuck around with, so we always messed around with each other.
I wasn't afraid of seeing her naked, nor was she. We had both seen each other walk out of the shower before. She even caught me jacking off once or twice, but she always left me alone.
To describe my sister, I'd say she was maybe 5'4"; black hair, bright green eyes. She had a petite body, but beautifully sized tits for her age. And the way she always smiled at me was the cutest thing I'd ever seen..
She was fast asleep in our living room, so I decided to go upstairs to my room. It was around midnight; I figured she wouldn't wake up and I wouldn't get caught. I pulled out my laptop, took off my clothes and got under the covers.
Now I have no reason to lie (like most people on here do), I have an average cock, around 6 inches fully erect. I found something on RedTube and started stroking away. I was just about to cum when I heard my door creak.
I quickly slapped my computer shut and flipped on the light. My sister was standing in the doorway with her hand in her panties and her eyes closed. As soon as I turned on the light, her face turned red and she started to turn away.
"Wait," I said.
She turned back around. I motioned her in and slowly started sliding my covers back off me to reveal my penis. She closed the door behind her and started walking towards the bed. My legs were spread pretty wide, so she climbed up between my legs and sat there, staring at my cock.
There wasn't a gross factor in this at all, like I thought there'd be. There was just a strong, sexual vibe in my room.
She started rubbing her hand over my balls, gently. I could only moan in anticipation. She gripped my dick firmly and started stroking slowly. I told her to put her mouth around the head, so she did. We were both young, so we didn't completely know what we were doing.
She bobbed her head up and down my penis, just an inch or two at a time. After a minute or two, she took her mouth off and spit on my cock. She rubbed it all over my shaft and balls.
She stood up and started taking her clothes off. First her panties, showing a tight, slightly hairy pussy. Then her shirt and bra. All I could stare at was her tits, perfectly rounded and smooth.
She turned around and stuck her pussy in my face while she put my dick back in her mouth. She started riding back and forth across my face. I stuck my tongue out and licked deep inside of her. I never heard her moan before, but she sure moaned now. No one was in the house, so we could make as much noise as we wanted to.
I spread her ass cheeks apart so I could dig in deeper. But just as I did this, she turned back around and started sliding her pussy up and down my shaft. This alone brought me straight to the edge quickly and I started cumming!
I must have been blushing from cumming so early, she started to smile and giggle while still riding her pussy lips on me. I shot maybe 4 or 5 ropes of cum and it was massaging between us.
"I can tell you've wanted this for awhile now," she said, "Wanna keep going?"
I smiled and nodded in approval. She wiped up some of the cum and lubed up my dick again. I was still hard and ready to go, like most teenagers, so she got on her knees above me and pushed my cock into her.
This was the first time I had felt this, so I must have had the weirdest look on my face. She seemed experienced for being 14, she knew how to ride up and down quickly. She moaned louder and her breathing became heavier. She laid down on me and was pushing back on my cock, which almost sent me over the edge again.
I felt almost awkward for a second, but I decided to take charge. I grabbed her by her ass cheeks and stood up while my dick was still in her. I flipped her around and put her in doggystyle on the floor. Immediately, this was my favorite position haha. I fucked away at her tight pussy for what seemed like a half hour. I got up enough courage to grab her hair in a ponytail and pull back.
When I did that I could see she had closed her eyes and was smiling, so I knew she liked it. I was soon about to cum and warned her.
"I want you to cum in my mouth," She softly moaned.
This sent me over. I pulled out quickly and gripped my dick hard. She flipped over on her back and I slid up, kneeling over her tits.
I started jacking quickly over her face. She opened her mouth and I aimed for it. I came about 7 shots straight to the back of her throat. I had never came so hard in my life, I had to grab her shoulder for stability.
She sucked on my head for a little while after. She smiled with that cute face that I remember so fondly. Afterwards, she grabbed her clothes and set off back to her room. I cleaned up with a towel, got back under the covers and fell asleep quickly.
Me and my sister have had a few times like this afterwards, which I might write about later if you guys liked this. I'm now 20, she's 18.
Sorry if it was kind of long! I was trying to remember all the details. Now I'm kind of hard writing this, so I think I'll go take care of myself. ;)
