Movie description: Stella Banxxx is Professor De Sergio's number one student in his environmental science course. So much so that he compliments her on the river samples she's been collecting, and he even goes as far as to offer her an internship next year. There's only one catch: he wants her to catch one more sample for him, but it's not anything she'll find within the local habitat. All she has to do is accept his hard cock between her big tits and inside her aching wet pussy, and she's as right as rain.
