It was still dark outside, and she tried to roll over and go back to sleep for another half-hour, but her mind drifted into dangerous thoughts, thoughts that wouldn’t allow her to sleep. She kept imagining having sex with Nick again four days from now. The four times they’d had sex so far had been amazing. On Tuesday of this week, it had been exactly a week since they’d had sex the previous week, so Jenn had come home from work, excited about the possibility of having it again—assuming Nick was in the mood. He’d been in the kitchen, and they’d made stilted conversation for a few minutes. Then Nick had said out of the blue, “I’m ready for sex any time you are.” Jenn had almost groaned in relief as she’d told him she was ready right then. They’d had sex on the couch and then against the wall in the hallway and then again in her bed. It had been a very good night. But it was only Friday today, and she’d have to wait until next Tuesday before they had sex again. It was written in their contract, and she had been the one to insist on it.
