My big sister is so damn hot. She has the biggest ass I have ever seen. I try to get a look every time I can. She is always catching me though. Today I found her humping her pillows. Wow! I wish I could be that pillow. Damn, she caught me again. What? You want to practice with me. Sure, I laid down, and she sat on top of me and started grinding on my cock. I got a raging hard on and she felt it. She liked it though. I suggested we try without our underwear and she did. Lets try just the tip. Wow! She was so hot and wet and tight. This was so much better than watching it on my computer. She thrust her hips and I pounded her pussy until her pussy creamed all over my cock. She started to say I had the best cock and she belonged to me now! Wow! I cant believe I am my sexy sisters first!
