Pretty little Linda Preston hotly jerked her dog’s erect prick on her bed as she listened to her mother getting fucked in the next room. A bathroom separated the bedrooms, but Linda could hear everything going on in her mother’s room. It was after midnight and Myra Preston had brought home another man.

Linda’s mom often brought men home from the bars she frequented. Sometimes, the man would be gone before Linda awoke the next morning. Sometimes the man would stay for days, drinking and laughing with Myra by day and fucking her by night. Ever since Linda’s dad had run off with a cocktail waitress, her mom had become a gorgeous, shapely cock-hound.

Now that she was a teenager, Linda patterned herself after her beautiful mom. What Myra like, Linda liked. And she often got very horny as she listened to some guy fucking her mother’s hungry pussy. She usually jerked off her dog, Rex, as she listened to the raunchy, lewd and exciting noises coming from the next room.

Just six months earlier Linda had discovered the joys of sex with the family mutt. After her father’s disappearance, the emotionally disturbed child began taking Rex to bed with her for comfort and solace.

Under the covers, she soon learned that the dog had a cock and that it got very large if she played with it. With her mom fucking hotly in the next room, bouncing wildly on her bed wit some guy, Linda enjoyed jacking her pet’s cock and making it squirt jism.

Rex’s big, stiff cock became important to the girl. Something to hold on to. Something to cling to in her loneliness and despair.

Without her dad around anymore, Linda turned to her mother as a model. When her mom found comfort in a bit, stiff prick, Linda found the same thing in her dog’s cock. When her mom finger-fucked herself for comfort, so did Linda.

The real fun of whacking Rex’s thick, red prick was only increased for Linda when she started fucking her middle finger in and out of her horny your pussy. The sexually disturbed girl found the combination exhilarating. She could jerk Rex’s big cock with one hand and still finger-fuck herself with the other.

Myra Preston was neglecting her little girl these days, but that was just fine with Linda. She liked the freedom suddenly thrust upon her because she could spend more time in bed with her best friend, Rex, a shaggy mongrel who had been good for nothing until Linda discovered his cock.

Recently, Rex started licking Linda’s hot little cunt, and she went wild with this new development in her sex life.

At first, she had be horrified and had tried to stop him from doing that. But being a sensitive girl, made extremely horny by her mom’s insatiable sex-hunger, she spread her pretty legs and found out just how wonderful it felt to have a big, wet doggie-tongue lap her cunt.
