It is a wonderful life having my very attractive 13 year old sister who is my lover. I used her mouth again while she was sleeping. She suckled the tip of the head of my d*** and swallowed most of my c**. I did it just for a thrilling reminder of when I used to do it before we came together s*******. She was a complete 12 year old virgin then. I pulled off her sleep shorts and she woke up slowly. I went down on her small, still nearly hairless, very tasty p****. She enjoyed trying to smother me as she came quietly. Mom was home, but asleep down the hall. I entered her having gotten hard again and loved her until I came again. Kissed her goodnight, then went back to my own bed.
