Lenna, Lenna, Lenna.... sometimes being the smartest in the family comes with terms and conditions, like helping your stepbrother with his science experiment for anatomy. At least Lenna is also good at being a slut! As soon as her stepbrother handed her a Hitachi, she went right to work. He watched as her legs shook and her eyes rolled to the back of her head. She came again and again until she squirted, just as he concluded would happen!
