All right, let's see if I get it right.
A woman is driving home through some backwoods country several states away from where she lives. As she's passing a house, her car breaks down. 2 guys are sitting on the porch in thier chairs, so she says to them, "Do you mind if I use your phone? My car broke down." They don't mind, so she calls a wrecker to get the vehicle towed to a repair shop. Once it gets there they let her know that they can fix the car, but it will take about a day. The 2 guys let her know she can stay there for the night since the nearest hotel is about 50 miles away. While she is there, they serve her a nice dinner and give her a nice place to sleep.
After dinner, she gets to thinking about a way to reward their hospitality, and thinks of something. She says, "I'll tell you what, since you are being nice to me, I figure I can repay you by letting you sleep with me tonight, but you are both going to have to wear condoms so I don't get pregnant." They agree, and have a night of passion. The next day, they drive her to the shop and her car is repaired, and she is back on her way home.
Several months have passed. We are looking at the 2 guys sitting on the porch. One says to the other, "Hey, do you remember that woman who stayed here months ago, cause her car broke down?" "Yeah, I do." "Do you care if she gets pregnant or not?" "Not really." "Good, let's take these condoms off then, they are starting to itch."
