Lilly looked down at me as I teased her clit with my circling tongue. She held tight to the shelves and begged me to let her down so I could be inside...of her. I licked her clit fast with the tip of my tongue randomly running the length of my tongue against it hard. Lilly wanted me inside of her but I wanted to taste her cum first. I licked faster pressing my lips against her pussy, my hands pulling her tight against my mouth. Her orgasm shook the rack and filled the empty store. The cold slab. . things like this just didn't happen.Like doing a pushup on the stairs, I was determined to throw him off of me. That's when his bared teeth appeared from behind and along side my face, and his growl coming from somewhere deep inside of him.Once again I froze, and once again I felt more of his cock go up inside of me. And it was beginning to feel thicker, and for a minute I caught myself comparing it to a mans cock. I quickly returned to the reality of the situation... a dog was trying to fuck. I knew she had a boyfriend, but I was naive enough to believe that they were just "friends". I had never even seen them hold hands, but when I came home unexpectedly early on Tuesday, I thought I had the house to myself until I saw a man's jeans on the floor of the sala, and my sister's bra and panties on the settee. I felt confused. Surely this couldn't be my sister upstairs with a man! But I could definitely hear her voice, husky and strange now, and I could hear the sound of her bed. Before I go into the story a brief introduction of Bhanu mommy. She is 43 years old now and works for an MNC as the marketing manager. Her body size is 36DD-30-38. She is the hottest, horniest and dirtiest and a loving mommy I’ve ever seen. She breast fed me till the age of 8 for which I’m very thankful to her. After returning from school, I used to unhook her blouse, hold her big milky boobs with both my hand and suck milk from the brown hard nipple. Since I’m her only son, she has shown all.
