About a week later, on a Monday evening, Mark Hollings sat down at a table at a diner nearby the school. It was just after basketball practice and he was very hungry. It was the usual routine for him on Mondays. His mom usually worked late on Mondays and he would have dinner by himself at the diner and his mom would usually pick him up later. His teammates would sometimes go out for a burger or pizza but Marc was very strict about eating healthy, preferring a salad or a tuna sandwich instead. He was in a good mood. Practice went very well and he had a good time on the weekend. His girlfriend, Brittney Lisle hosted a party which all of his teammates attended. He was feeling very lucky having such a cool girlfriend. She hosted a huge party a dared not to invite Kathryn Merteuil, the unquestionable leader of their class. Her step brother Sebastian Valmont was there and told him and Brittney how relieved he was to be having a good time without his evil step sister around. A minute after he started eating a beautiful blond showed up asking if she could seat next to him. She told she saw him at a basketball game and remembered how good and handsome he was. Mark was somewhat bewildered but allowed her to sit next to him. She introduced herself as Michelle Blair. They talked for a while and parted when Mark's mom arrived to pick him up.

Several days after their encounter, Michelle called Mark. He was surprised to receive a call from her and she explained she looked him up and wanted to get together. Mark said he had a girlfriend but eventually was persuaded. After that, things progressed quickly, and in a couple of days a rumor started to surface over the school saying that Mark was seeing someone behind Brittney's back.

"Now what?" Sebastian asked Kathryn after they got home from school.

"Trust me, I know what I'm doing idiot!" She replied.

"Why go through all this trouble? Hiring a call girl to seduce him? You know, people will actually suspect that you did this!"

"And here comes the brilliant part of plan. Starting tomorrow, a rumor is going to go around the school saying Kathryn was so pissed she wasn't invited to Brittney's party that she hired a call girl to seduce her boyfriend."

"So you really want people to know that you are behind this?"

"No…God you're an idiot! Just a couple of days after that everyone will find out that Michelle was also seeing Brian Chase and Shane McCollum who are with Mark on the basketball team! And people will also find out she was seeing a couple of guys from Northwest Prep School's basketball team."

"Geez sis, you paid her to have sex with all those guys?"

"Wrong again, idiot. I want a fuck him, I don't want him having sex with call girls before I get to him! She's not sleeping with them, just being seen with them."

To Sebastian's amazement everything went according to Kathryn's plan and after a week it was known to everyone that Mark Hollings cheated on Brittney Lisle with some basketball groupie. Brian Chase and Shane McCollum were also seeing her but they did not have girlfriends so that was not an issue. However everyone also found out that Northwest Prep School's point guard who did have a girlfriend also was seeing that Michelle girl, but Kathryn didn't care about that. The final stage of her plan was about to take place.

Kathryn and Sebastian's parents were due to be away for the weekend and that's when it was all supposed to happen. Kathryn called Mark Hollings and asked him to come over for a talk that Saturday night. Mark was depressed about being dumped by Brittney and was reluctant but Kathryn insisted she had to see him and asked him to be at her house at 7 o'clock. Sebastian called Brittney and said he wanted to talk to her. He said they could swim around in the pool and she could bring a bathing suit if she wanted. He asked her to come at six thirty so there would be no chance she would run into Mark. On Friday, Kathryn and Sebastian had their usual Friday session but they were both nervous Sebastian didn't even mind finishing well before 9 o'clock.
