I'm 5'3', thin build, 34 A, Jess (16) is 5'5', slightly bigger build, 36C. We both have light blonde hair.
I was at home one day, and I was feeling kind of horny. I happened to notice my sister's door was open a crack. I glanced inside, and saw her facing away from me with her pyjama bottoms and no shirt on. I was curious, and figured now was my chance. She was kinda surprised to see me there, but she was not mad when she turned around with her hands over her breasts. I told her I wanted to know what a more mature woman's body looked like, and I didn't want to ask mom. She understood, and she was happy to show me her body, but I had to show her mine. Fine with me.
She told me to take my PJ shirt off, so I slid it off, revealing my boobs. She took her hands off her boobs and let me feel them. She had nice pink nipples, already rock hard. Her tits were really firm, mine are kind of soft yet. We then took off our PJ bottoms and panties. We spread our legs facing each other. She had a nice bush, I just had a few hairs up top, and a lot of fuzz. We were both pretty wet, our pink pussy's were started to swell. She then offered to give me an orgasm.
I sat on her computer chair, legs spread, with her on her knees in front of me. She touched my thighs, and I could feel myself getting hornier. She wasted no time rubbing my clit and shoving her fingers up my screw hole. I started rubbing my hoots, and soon my orgasm came on. My legs tensed, I started to moan as best I could, and it hit my body like a wave. It was the most incredible feeling. She then let me watch her play with her dildo. I rubbed her boobs as the big pink toy penetrated her. When she came, she said it was her best orgasm ever.
Have fun out there!
