The reaction Mac's body was starting to have to the feeding was a reason why sex and violence tended to go hand-in-hand for her. After the initial shock of pain, things blurred together for Mac, so naturally, this would follow that same course. She was relieved, actually, when he pulled away, not wanting her body to betray her murderous thoughts. She was glaring at him, watching for sudden movements, on edge because he had caught her off guard once already.
But Mac did hesitate when Jack offered her the chance to fight. Was it a trick? Would he only punish her for it? What the fuck could she do to him anyways? But then he slapped her, and her eyes came back to their alpha red color, pissed off that he had gotten the drop on her. Again.
Even though she knew shouldn't actually win against a vampire his age, at the same time, he was demanding her to fight him. So if she died in the process, at least people could say she didn't go down without a fight. She struck at him, making as if she'd hit with her right but actually struck with her left then her right. She wasn't holding back like she had at the bar. Those guys were human, Jack was not. She punched at him, clawed and kicked, while taking glances to look for something she could use as a weapon. The shirt she was wearing stayed on her shoulders, but with the buttons no longer intact, it was open in the front, not that Mac even noticed at the present moment. She wanted to get some hits in while she thought she had the chance.
