My sister is a 19 year old brunette. She’s about 5’10 with legs that don’t stop, a perfect ass and a medium set of tits. She didn’t hide her body from me at all and I think she knew I liked looking at her. My sister and I weren’t really close when she hit 14, she didn’t like when I was watching her, admiring her budding body. She did like teasing me though. She’d always bend over in a low cut tank top giving me a view of her milky white tits or short shorts giving me a view of her panties. Each time I had to run to the bathroom to jerk off and she knew it.
One day she caught me jerking off in the bathroom, I didn’t think anyone was home so I left the door unlocked. I was standing there stroking my cock thinking about cumming on her and she stood there with a look of shock on her face when I started blowing my load and said her name. I heard her gasp and I turned to her and blushed and she ran from the doorway. I cleaned up and pulled up my pants then went to her door. I knocked and she said “come in” so I did. She was sitting on her bed and wouldn’t look at me. I told her I was sorry and she said she wouldn’t say anything. I said thanks and left her alone. A few weeks later I was taking a shower and she was home. She knocked on the door and said it was an emergency, so I opened the door. She ran over to the toilet and pissed so loud I could hear it over the shower. I heard it flush and thought she would leave. I kept showering and didn’t think of her still being in there until I heard the curtain open and felt two tits on my back. My cock started growing and she whispered in my ear “I see my big brother is getting a hard on for me.” She kissed my neck and gripped my cock. She started stroking it until it was completely hard. She told me I had a beautiful cock and came around my front and kissed me deep and hard. I felt her tongue slip into my mouth and she sucked on mine. I squeezed her ass and felt her bare pussy on my cock. I didn’t know she shaved her pussy but what a great surprise! She told me we should get out of the shower and I quickly agreed, we dried each other off and she led me to her bedroom by my very hard cock.
