Natalie Brooks is having a great time at college, and she wants to share all the fun she has been having with her loving bro. He picks her up in his car, and she tells him all about it. It turns out, her favorite part of the whole thing has been the flashing! Of course, when Natalie gets home, she tells her stepmom a whole different story. But when she and her bro finally get a minute alone, Natalie assures him he has nothing to be nervous about when it comes to college. She shows him all he needs to know by offering him a helping hand like she used to. She pulls out his cock, and boy has it grown! She spits on it and goes down for a sloppy, slobbery blowjob. Then he admits his cock right into her tight collegiate slit for some rough cramming before the cum test. Finally, he makes the grade by cumming all over his sisters face. Too bad stepmom found out in the end!
