When I saw my sister sleeping with her titties visible through her tight little shirt, I had an instant hard on and had to take a peek. My heart started beating faster and faster as my hand got closer to her boobs. I slowly took the edge of her shirt and started pulling it down very slowly, more and more of her boobs became visible and then her nipple just popped out. My heart started beating so fast! The sight as amazing, I had noticed she had been growing but for the first time I was actually looking at my sister with her tits out.
Now my boner had taken over, I wasn’t scared anymore. I took my dick out and just pulled her shirt down and exposed her other tit and just started pinching and playing with her nipples. I made my way down and started playing with her pussy from the side of her tiny shorts. It was so silky smooth, so soft, I couldn’t stop. I started licking her nipples and masturbating her teen pussy and just started cumming bucket loads right on her tits and face without even touching myself. She was covered in my jizz. It was the best orgasm of my life and my dick was still hard.
I had to cum again, I put my dick on her now sloppy tits and started rubbing and fucking my cock with her boobs, using her tits to jerk my self off. It took seconds until I unloaded all over her. I looked at her and she was white from all the jizz I unloaded all over her body. Then I looked down to her waist and saw her hand playing with her cum covered pussy. She stopped a sec after I saw it, but I knew what I saw. She was pretending to sleep the whole time and was so turned on that she had to play with herself with my cum. There was no way I was leaving now, she was mine.
