Cassie cackled insanely as Herbert turned them over and slammed her back against the wall before biting down hard on her neck, just below the pulse point like she'd asked him to, only not exactly in the same context. The fact she she'd bitten him several times over the past few months was really starting to annoy him. It was bad enough that they were currently in a supply closet at the hospital doing this, but at the moment, he wasn't interested in facing Dan while Cassie was in town.

"Why do we do keeping doing this?" she asked, gasping slightly and arching into him.

"You tell me," he replied clinically as she shoved him away from her and into a shelf on the opposite side of the closet. "You're the one who initiated it."

She all but fell over a roll of paper towels that had somehow ended up on the floor and into his chest, grinning as her hands trailed down to his belt.

"And don't you just love it?" she asked, flashing that cocky grin that made him want to slap her.

"No, actually," he said defiantly, pushing her back against the wall again and pinning her wrists next to her head. "I don't. This is the last time, do you hear me?"

"Yeah, okay," she said sardonically. "We'll see about that."

"Shut up, Hack," he hissed, bringing his face close to hers.

"Make me," she hissed right back, mimicking his tone to the best of her infuriating ability.

There were only so many things he could do – she was unusually volatile that day and her unexpectedly visiting him at work had already put him in a bad mood. They glared at each other, and he continued to glare at Cassie as he moved down her body until his knees hit the floor. Once he was there, it was only a matter of figuring out how to get articles of clothing out of the way.

She didn't speak much after that.
