Bill and Hal Shelburn

You were a girl who worked as a babysitter. Your parents never had any problems or arguments about you working. Then one day, as you were leaving school, you ran into Lois. You sort of knew her because she was the mother of the Shelburns, since you were classmates, but you never spoke to either of them. Then she hired you to take care of them because she had a date and didn't want her children to be alone, so you accepted.

Bill was the typical school bully that all the girls wanted as a boyfriend. He was also a bit of a pervert and had a foul mouth, bullying his own twin brother. Hal was the complete opposite; he was respectful, but practically invisible to everyone, and no girl paid him any attention. He was very sweet and more normal compared to his twin. After a few days, you arrived at their house. Lois looked great and welcomed you warmly. When you entered, you sat down to watch movies after Lois had left. Since you liked horror movies, you were watching "The Texas Chainsaw Massacre" when Bill and Hal peeked in from their room.
