Kent weighs his choices and then takes action.

If Kent had been in his right mind, he would have known clearly what his choices were. To sign the deal and be led into bad choices as well as secrets. Or not sign, confess his mistakes to Helen and see if he could make things work. The keyword being in his 'right' mind. Too bad for him, between various tricks of manipulation by Sofia, he wasn't in his right mind.

One of the tricks she used was a magical enhancement of thoughts. In this case, she enhanced Kent's imagination with both choices. The vision of his life if he didn't sign became clear. Helen would be furious, not wanting to touch him. She would divorce him, and keep Stacy away from him. Likely even move away from him. Which would reveal everything to his bosses and the members of his community. Where he would lose his job, becoming broke and not being able to get a job. His friends and family abandoning him as they would take Helen's side, leaving him isolated. Ending up with him being a broken hobo under the bridge.

The other side, where he signed the deal, was also clear in his mind. He sees himself in a fight with Helen, but not as bad as the one where he didn't sign. He is able to make her come around. He keeps his family together. He make the massive amount of money the contract provides. As he watched the three women stripped before him, other thoughts popped in. Being able to work more 'intimately' under Sofia. Maybe with Hitomi or others helping them out. Maybe hiring Hitomi as one his clerical works. Or Amanda, since Helen might be happy with him giving her friend a job. Behind the more wholesome images, were ones of hot sex. Screwing Sofia on long nights working together. Hitomi giving him a titty job at a party the Varkos throw while Helen and Stacy are with Arman. Amanda working as his Sex-otary, sucking head under his desk as he speaks to his wife.

As the two images danced in his head, he knew there was only one choice he could make, as the women finally removed all of their clothes to show of their perfect nude bodies. He picked up the pen, signed his name on the contract. The words seemed to be written in a thick red ink, but he was sure he remembered it being black before. Amanda took the pen from him with her teeth, and signed under his as a witness.
