Ohohoh that possessive growl. Oh that gave him shivers indeed. Natsu made sure to not let her have any easier time pulling back from him. After all that was his only way to fight back if not by using his hands.

Another heated groan was her reward for those purrs against his ear. Oh she was playing with very wild fire right now and the biting and grinding only made it harder for him to stay still. "Ngh dammit Lucy you're not makin this any easier on me." he managed to growl out his warning as he tried raising his hips up to meet her motions to hopefully tease her at least half as much as she was doing to him.
