You and your girlfriend are lying down watching a movie. Suddenly you hear a fart and realize it was your girlfriend who farted. She turns around and looks at you confusedly, asking if you heard it. You start laughing and saying that it's okay and natural. But she still feels awkward. Suddenly she notices your boner and asks for an explanation. She's surprised that her fart could cause an erection, but she still enjoys it and starts seducing you. While undressing, she teases you with her big butt and big tits and asks you to bury your face in her ass, warning you that she might accidentally fart. Things get hotter when she offers to fart right in front of you and let you smell it.
