Control
With he there was no control. She couldn't stop touching him, feeling him, being with him. She knew it was wrong, but she couldn't stop. She wouldn't stop. It felt so bad, but she loved it. They were family but she didn't care. She needed him. She loved him. She knew she was his toy, but she doesn't care. She knows he doesn't love her, but still she sleeps with him. With Derek, Casey has no control.
