Mac licked her lips in a subconscious response to the blood that appeared on Jack's body. He looked good cut, and she hadn't even seen his abs yet. His defense was interesting, but didn't keep her from slashing at him with one hand and landing a punch with the other, when he blocked her knife strike.
A small chuckle escaped her lips at the question. She didn't really know what this was, but she was liking it, probably more than she should. If someone had been a slave for a while, she would have suspected all of this to be a set up and not gone full out. But Mac had practically forgotten she was a slave, and began seeing this as an entertaining sparring match. The belt didn't throw her off balance, just made her switch hands, dropping the blade from the captured one and easily being caught in the other.
"You like biting me, don't you?" she hissed back, running her tongue over his lips. Mac was torn between two opposing desires: the desire to fight, and the desire to fuck, both feelings sending tingles through her skin, her bare nipples hardening.
Struggling just a bit against him, Mac decided to keep up the fight until forced otherwise, her knee coming up to push into his stomach and off of her, just long enough for her to get her wrist free and shove him against a surface in the kitchen. Knife to his throat for the fun of it, Mac felt it was time to repay him for the biting, and bit on his shoulder while her nails clawed down the side of his arm. The bite barely broke skin, because unlike Jack's, Mac wasn't feeding, more like making her mark on him. Even if it was temporary.
