He didn't know it quite yet but she had found his hidden messages on skype, email, facebook and even had seen his deleted messages on his phone. She then started to check phone records and saw that he had been talking to numerous women while they were dating and even as soon as the last week. She started to count up the time and noticed that it equaled many hours on occasion and sometimes text messages were sent for close to two and three consecutive hours when he was at work.
She then looked at his website history and saw that he liked to read sex stories on various websites (probably a reason for his lack of endurance in bed) and noticed his favorite kind to be incest/taboo and BDSM so she started to look into torturing him and ways that would hurt him but pleasure her.
After many hours of looking at various websites she found chastity belts and started pricing them. She wasn't worried about price as it wasn't like he was going to be taking it off anytime soon but she also didn't want to hurt him too badly.
Now Cheryl wasn't a evil woman so she called a few girlfriends who had problems with their significant others cheating and let them draw up a contract for him to sign and also shown the details of some of her plan so they could add to it.
Her friends were very meticulous in thinking up the contract and added many things that would basically protect Cheryl but hurt Cory if Cory was to try and take it to the police or to court.
One of the major things Cheryl wanted to do was punish him for his time talking and texting other women so she came up with a time for every detail.
