My sister, who is sleeping with her buttocks exposed, does not wake up at all! I was just playing a prank on her, but she couldn't take it anymore and decided to give me a butt-job! She was so happy that she shot her load right away! When I tried to penetrate my sister in her sleep, she woke up and noticed that I was still asleep, but she got excited and said, "I can't help it, I'll just rub it..." She let me give her a butt-job, but I couldn't hold back anymore and penetrated her! She was so excited that she let me give her a butt-job, but I couldn't hold back any longer! She was so flustered that she couldn't help but cum inside of me three times in bed!
