In Professor De Sergio's environmental science course, Stella Banxxx is by far the best student. He even goes so far as to offer her an internship for the next year after complimenting her on the river samples she has been gathering. The catch is that he only wants her to collect one more sample for him, and it won't be anything she can discover in the surrounding environment. She'll be as right as rain if she just accepts his firm cock between her large tits and inside her throbbing wet pussy.
