Her Daddy had whisked her off to bed and Kayley smiled at me with those big China blue eyes. Kayley is a lovley 9 year old girl who is as petite and lithe as a porcelin doll. About 15 minutes later, Kayley's Mom, Sharolynn, whispered in my ear "Uncle Mark, come upstairs, I want to show you something" We both got up off the sofa and I followed her upstairs. Sharolynn cracked the bedroom door open and we tiptoed in. We tiptoed up to the head of the bed where Barry, Kayley's Dad, was sleeping. Sharolynn said "Ohhhh, Uncle Mark, I think we are too late" she furrowed her brow to make the point valid. She slowly and gently peeled back the quilt. The image was riveting! Kayley's head lay on her Daddy's chest while her petite hand was resting about 1/2 way down the most massive cock I had ever seen. It was at least a foot long! Her full lips were somewhat parted and a thick strand of sperm looped out of her mouth and connected with the slit of an enormous cockhead the size of an apple. Her silk "jammys' were wet with great spots of sperm. The sight was obscene! Kayley began to stir as if from a deep sleep. She raised her head and looked up at us somewhat disoriented. Sharolynn gently reached down and picked up the tiny child. A copious amount of sperm was in the child's hair. Sharolynn wispered "Uncle Mark, could you go to the bathroom and get a clean towel please?" I came back with the towel and tried to give it to Sharolynn. But Sharolynn shook her head no. "Place the towel on YOUR shoulder, uncle Mark, and try to take responsibilty for your neice!" she whispered in a commanding tone. "You have to burp her, Uncle Mark, she has a lot of her Daddy's semen in her stomach and I need for you to help around the house!" Sharolynn quipped. I placed the towel on my shouler and Sharolynn gently passed Kayley to me. I held the lovely little angel's ass in my left hand and cradled her close to my chest. She was so light warm and soft. She snuggled into my neck with her semen soaked face and neck. "Uncle Mark is going to burp you, give you a bath and then put you to bed baby..." whipered Sharolynn. She then leaned over and kissed Kayley on her sperm laden lips and then tip-toed to the door and held it open for us. I almost fainted! My cock twitched and jerked violently! I walked through the bedroom door, passing by Sharolynn, when suddenly Kayley lifted up her lovely head, looked into my eyes, and "burped up" a wad of her daddy's semen right in my face! Before I could get angry, Sharolynn snapped "Uncle Mark! If you would have burped her like I asked this would never have happened!" Kayley leaned back looking chipper and awake and exclaimed "Oh Uncle Mark, I feel better now!" She then looked at me in a very impish way and said "Are you going to give me a bath now?"
